implication [end times]

The iron gate outside the courtyard was knocked loudly, and the two chickens in the fence in the courtyard puffed up their feathers and clucked in fright, stretched their necks and raised their paws and ran back to the nest.

"Ran Yu, Ran Yu, are you there? I'm on my way to find you! Cook me something delicious for my last meal!"

Ran Yu put down the thick "City Entrance Examination Ideological and Moral Class Intensive Lectures" in his hand, stood up and walked to the courtyard: "He Rongsheng, you scared my chicken like this, don't even think about eating eggs tonight."

The courtyard wall is made of reinforced concrete, about [-] meters high, and dense grids are stretched on the wall, which is upside down on the entire courtyard like a big bowl.Occasionally, a half-meter-long sparrow flaps its wings covered with slippery scales, dances its slender and soft tail fin like a streamer, and when it stretches out its sharp claws to try to rest on it, it will suddenly arouse violent flames accompanied by sparks. There was a stinging sound, leaving a long-lasting burnt smell in the air.

Just under 100 years ago, finfish was just the name for a creature that lived in water.In other words, all fish, algae, animals and plants are just creatures that exist in rivers, lakes and seas, and will not invade the land and sky in various mutated forms as they do now—not to mention extremely dry places with an average altitude of more than 4000 meters. Mountains of the Qinghai-Tibet Plateau.

Of course, it was difficult for domesticated chickens to survive at that time.Therefore, the drastic ecological changes in the past hundred years have brought some benefits, such as increasing the types of food.

At noon in early June, the sun was at its peak.Ultraviolet rays pass through the thin atmosphere and pierce human skin like fine needles.He Rongsheng, who was busy outside the door, wrapped his sunscreen hat tightly, felt that the small wound on his face was itchy from the sweat, so he raised his hand and wiped his face.

He Rongsheng obviously forgot how many tragic battles he had experienced along the way, and only after wiping his face did he realize that his hands were all stained with blood.Just then, the door opened.

The young man who opened the door was tall and straight, with a handsome face, and his loose gray-blue cotton and linen short sleeves set off his exposed skin with a cold and moist jade white.It may be because he seldom goes out, but the scorching sun on the plateau did not tan his skin into the ocher red common to people outside the city.

What a good-looking person, He Rongsheng thought to himself, if appearances were included in the city entrance examination, Ran Yu would definitely be able to increase the scores that were dropped by the ideological and moral courses by a large margin.

This thought was fleeting, because in the next second He Rongsheng pulled out a dagger from his waist like a conditioned reflex, blocking Ran Yu's sudden dagger.

The blades collided, making an extremely harsh scratching sound.The two chickens in the nest trembled even more.

He Rongsheng held Ran Yu's wrist with the other hand, and said helplessly, "It's not my blood, it's not infected, it hasn't been transformed."

Ran Yu's strength remained unabated, and his voice remained calm, as if discussing business matters: "If you fail the entrance exam, let's go to the post office and apply for a different route. We're tired of walking. Both of us have worked for five years, Lao Wang You should agree, and you apply with me."

As he said that, Ran Yu pressed down the dagger in his hand, as if he was a bandit leader who said "I'll kill you if you don't agree".

He Rongsheng rolled his eyes: "First, wake up, I have worked for five years, but you have only worked for two years. Second, you are a part-time job, and you have no seniority at all. What conditions are you talking about?"

Ran Yu withdrew the dagger, straightened his unwrinkled clothes, acted like a refined and courteous host, and welcomed He Rongsheng into the door: "Come on, come on, why are you still carrying something, it's too polite."

The heavy iron gate closed behind them with a muffled sound.

He Rongsheng only felt a lightness on his shoulders, and the tactical bag full of weapons and guns arrived in Ran Yu's hands at some point.

He Rongsheng's alert value was immediately full, and he wailed, "This is all my belongings, brother, save some for me!"

Ran Yu had already hugged the bag like a baby, turned around and walked into the yard, and said without looking back: "I'll just take a look, if I don't take yours... I won't finish it. Look at your dirty body. Go to boil water for a bath. Ran Qiu—”

A boy in suspenders came out of the room slowly, stretched his waist and asked, "What's wrong, brother?"

For a moment, He Rongsheng forgot that his tactical bag had fallen into the hands of the thief.

The boy in front of him was about fourteen or fifteen years old, with short curly hair curled up fluffy, white lips and big eyes. At first glance, he looked like an enlarged version of a beautiful doll.

There are three people in the courtyard now, two of them are clean and tidy, and they are of great ornamental value.There was also a bloody, gray face, and a disgusting smell of fermented blood, sweat and minced meat.

The person involved, He Rongsheng, didn't care about complaining about himself, and quickly grabbed the corner of Ran Yu's clothes in front of him and asked in a low voice, "Do you have a younger brother?"

"That's right." Ran Yu's hand quietly touched the dagger at his waist, "You don't know?"

He Rongsheng hurriedly raised his hands: "You never talked about your own family affairs at the post office, who would know about this? Besides, you haven't come to work for more than three months, we didn't hear from you, and we thought you had been eaten long ago. "

"Didn't I ask for leave?"

"It's easy to ask for leave and it's hard to sell it. How many of our colleagues said they asked for a few days off and never showed up again?"

Ran Qiu leaned on the door frame and interrupted their conversation: "Hi uncle, do you want to take a bath?"

"Okay, okay, the child is really sensible... Oh, no, I'm as old as your brother, I'm only 20 years old, and the kid's eyes are not very good."

Ran Yu waved at Ran Qiu: "His name is He Rongsheng, my colleague at the post office, let's call him brother, you take him to the woodshed to bring some firewood to boil water. Just give directions, and let him do the work."

He Rongsheng waved his hand politely: "There's no need to boil water, it's summer, I just take a cold shower."

Ran Yu patted him on the back: "You look very tired. I have no medicine for you when you catch a cold after taking a shower. You have to go to the examination room tomorrow."

Ran Qiu shrugged, scratched his curly hair and said, "Brother Rong Sheng, come with me."

He Rongsheng was indeed exhausted.He lives near the post office, more than 100 kilometers away from here.Halfway through his drive, the old car was besieged by five or six mutant wolves and completely scrapped.Fortunately, those wolves seemed to have not eaten for a long time, and they were exhausted. He Rongsheng fought with them for nearly half an hour, and finally escaped after exhausting two magazines and hacking a hatchet.

Fortunately, there were no swarms of ferocious beasts on the rest of the road, just some mutated birds and snake rats making a fuss.He Rongsheng walked for a day and arrived at the gate of Ran Yu's house. He was going to rest here for the night. The next day, he went to the main city with his examiners to confirm the examination room.

The closest to He Rongsheng and Ran Yu is the main city of Aibo, which is [-] kilometers away, and it is also the largest main city in the Asia-Pacific region.

The population of the main city of Aibo has exceeded 3000 million, and the offspring born in the city will automatically be eligible to live in the city.If retail investors living outside the city want to live in the city, they must pass the entrance examination that is only once a year.

Ran Yu's residence was on the only way He Rongsheng went to the main city. The two of them discussed it when they were working at the post office more than three months ago, and they went together before the exam.

He Rongsheng was no longer polite to Ran Yu, and just sighed: "It would be great if we could really pass the city entrance exam. Then we can take a hot bath every day, throw away dry food and eat soup noodles every day, and use water and electricity as we want , and don’t have to fight monsters every day, don’t have to worry about survival issues… Just thinking about it makes me feel happy.”

"How is your review of the ideological and moral class?"

"It's not bad, the correct rate is barely 90.00% or more, how about you?"

Ran Yu, who had just approached the firewood room with He Rongsheng, paused, turned around and was about to leave: "You go take a shower, I'm off to review."

Ran Qiu, who was scratching his curly hair, stepped into the firewood room first, and saw a sparse pile of firewood, so he tilted his head and called Ran Yu: "Brother, the firewood is almost gone. We don't have any firewood after he takes a bath." Let's cook."

Ran Yu carefully selected two short knives that fit the eyes from the tactical bag he just got, and took a pistol and put it behind his waist, and said: "Let him wash it first, and I will go to the mountain to cut firewood. You are at home Wait for me later, and eat two boiled eggs first when you’re hungry. By the way, didn’t the generator always make strange noises yesterday, let him fix it while the water is boiling, and he’s idle anyway.”

Ran Qiu nodded, sent Ran Yu to change his clothes and get his equipment to go out, then went back to the woodshed and asked He Rongsheng to fetch water from the well in the yard first, and then repair the generator. The arrangements were clearly made for him.

Ran Yu's home is at the foot of a barren mountain, and there is no other family within a radius of [-] kilometers.

This low hill is bare and composed of fine sandy soil and stones, with a few clumps of salt firewood semi-shrubs scattered among them, most of which are taupe wormwood and brown red sand.The bark of these desert plants is mostly cracked, and the leaves are pointed and thin. They stubbornly reduce water evaporation in the arid environment in order to survive for a few more days.And as long as you climb over this small hill, you will see another slightly higher mountain after walking for three to five minutes. The vegetation on the top of the mountain is various and dense, the leaves are stretched and wide, and there is even a shallow stream flowing between the mountains.

The dryness and the wetness are extremes here.Gray-yellow gravel barren hills live next to lush woods and streams, and coniferous and semi-shrubs and deciduous broad-leaved forests face each other across the mountain, just like people outside the city and people inside the city.

Since the era of the main city, resources have been infinitely concentrated in the city, and infrastructure such as water and electricity outside the city has long been unable to supply.A post office set up every four to five hundred kilometers is a way for the main city to communicate with retail investors outside the city. Working at the post office to deliver goods can receive diesel and medicine as wages, which is also the main reason why Ran Yu works there part-time.His parents died early, and he lived in a mountain den with his younger brother.In recent years, the lack of resources and the deterioration of the environment have become more and more serious, and the lives of retail investors have become increasingly difficult. Ran Yu must seize the opportunity of this city entrance exam—he just turned 20 this year, and he meets the requirements of 20-22 years old for the exam—his parents What he was most worried about before he died was the exam that was about to determine his fate.

The difficulty of the city entrance examination is getting higher and higher year by year, and the number of participants is increasing year by year, but the number of admitted places is always ten.According to many retail investors outside the city who failed the exam three times, although 20-22 years old have three chances to take the exam, these three chances are not completely equal.In addition to the reasons of competitors, the main city will also take the age factor into comprehensive consideration. The age of 20 is the most favorable time for candidates to go ashore.

Ran Yu walked quickly past the swaying ferns, and at the same time imitated the real questions from previous years to give himself a self-test in his heart.

Question: According to the relevant knowledge of biology, chemistry, history and geography in the "General Course for Entrance Examination", explain why the plateau mountain climate, temperate marine climate, and temperate continental climate coexist in the current Qinghai-Tibet Plateau region, and from the Analysis of the variation process of the species of pikefish and the law of the spread of "sea ghost virus". (30 points)

answer:……

Before Ran Yu had time to list one, two, three, and four points in his mind, he had already reached his destination.

In this season, the vegetation on the mountain seems to have gone crazy, and the weeds in the crevices of the stones wish they could grow taller than a person.As you get closer to the foot of the mountain, you will be greeted with the smell of soil and leaves steaming and mixing together. Looking up, you will see a lush dark green and brown, against the blue sky, the color is bright and eye-catching.

When summer comes, the dense forest blocks the sight, and it is difficult to escape when encountering danger.Ran Yu seldom went to the top of the mountain anymore, and only picked up branches, chopped bamboo and trees in the lower places, and sometimes came to dig some wild vegetables.

While thinking about the answer to the question in his mind, Ran Yu swung his ax vigorously to chop down the tree, but did not notice that there were two pairs of greedy eyes staring at him unblinkingly in the bushes in the distance.

"This man has no equipment on him, and he doesn't even have a communicator on his wrist. He looks like someone from outside the city."

"That's right, and he's chopping firewood and digging wild vegetables. He probably lives nearby and came out for supplies."

Sun Da looked at the thin figure in the distance from the gap between the leaves, and was about to go out with a knife in his hand, but was stopped by his brother Sun Er.

"Brother, people outside the city usually live in groups. That person dares to go to the mountain to chop firewood alone. No matter how you think about it, he is a ruthless character."

Sun Da frowned, and the scar on his forehead twisted accordingly: "Yeah, look at you, do you understand that this is an opportunity? How many days have we been out of the city? If we can't complete the task quota, the guy in the city will treat us badly." Ruthless?"

Sun Er shivered, gritted his teeth and said, "Then let's go together."

Sun Da suddenly showed a smile of unknown meaning: "Don't worry, you can't lose money on this deal. That man looks very handsome, with delicate skin and tender flesh. We can play around before handing it over."

After Sun Er thought about it like this, his heart itched, and his worry and caution were immediately forgotten.

Ran Yu was throwing the bundled firewood into the big bamboo basket when he suddenly heard the sound of a small branch being trampled off behind him.He didn't look back, and dodged a heavy punch with a dodge.Suddenly, another person jumped out with a knife and slashed at him. Ran Yu elbowed the person behind him until his nose bleeds, and then flew straight to kick another person.The whole series of movements are fast, precise and ruthless, so smooth that people can't catch the slightest loopholes that can be attacked.

Sun Da stretched out his hand to wipe the nosebleed, and felt that the bridge of his nose was almost broken.At this time, Sun Er had already got up from the ground, and swiped a short knife to chop at Ran Yu's body.Ran Yu waved his ax unceremoniously, and he made the heavy woodcutter like a light fire stick.

After a few rounds, seeing Sun Er was at a disadvantage.

Sun Da wanted to catch it alive, but this prey was really tricky, so he wiped his nosebleed and took a few steps back, took out a gun from his waist and said sharply to Sun Er: "It doesn't matter if it's disabled, this thing is really difficult to deal with. You stay away."

At this time, Sun Er was wrestling with Ran Yu, and before Sun Da had time to aim, Ran Yu had already broken away from Sun Er, and with a sharp roundabout kick, Sun Erzhong was kicked back to the tree trunk.Sun Er spat out a mouthful of blood and passed out on the spot.

Ran Yu didn't stop at all, grabbed the vines hanging from the tree with his hands, kicked the trunk a few times with his arms and long legs as if walking on the ground, and disappeared into the thick green canopy in two or three strokes. Apes in the mountains.

In just the blink of an eye, the person in front of him disappeared.

Alarm bells rang in Sun Da's heart, but it was too late.There was a sudden sharp pain in the back of his neck, and he passed out.

Ran Yu tied up two unconscious big men with firewood rope, searched them, and seized three field knives and two guns with satisfaction.The handle of the knife was painted dark green and engraved with a simple and exquisite V-shaped pattern. Ran Yu didn't have a knife of this color, so he happily put the spoils in his bag.

These two people didn't wear any conspicuous electronic equipment, and they seemed to be deliberately pretending to be outsiders.However, Ran Yu worked in the post office for two years and met many people in and out of the city. He keenly noticed that although it was difficult to distinguish from the appearance, there was a subtle difference in temperament between the two.

Based on Ran Yu's limited literary level and life experience, if you have to make an analogy, this may be the difference between a domesticated chicken and a pheasant. The former shrinks its neck and runs away when it hears any movement, while the latter even has a wild vigor on the comb. Son.

In the vast land outside the city, it is not uncommon for people outside the city to kill each other in order to plunder living materials.Ran Yu has also met several times, and if the other party does not leave him a way to survive, he will naturally not show mercy.

Ran Yu walked around the two of them a few times, not quite understanding why city people with abundant resources and enviable resources would come out to find trouble.

So he impatiently held a person in one hand and roughly pressed their heads into the nearby stream.It didn't take long for the two people who were tightly bound to wake up, coughing and writhing crazily.Ran Yu lifted the heads of the two out of the water, but heard the two utter wild words one after another:

"Be more sensible, let us go, or you will look good!"

"Do you know who we are? Don't be ignorant!"

Ran Yu thought they were noisy, and glanced at their necks impatiently. Just as he was about to test whether the newly snatched knife was sharp, he caught a glimpse of the electronic watch on one of them's wrists out of the corner of his eye.

"It's twelve o'clock now?" Ran Yu asked.

Sun Er didn't know why, but when he saw Ran Yu acting like a bandit robbing, his attitude suddenly turned around: "Yes, you like this watch, right? You can take it, as long as you let us go, the electronic watch We will give you all kinds of equipment."

Ran Yu didn't answer, he tore two pieces of cloth from Sun Da's body, knelt down and wrapped two large piles of soil with the cloth, and then stuffed them into their mouths.The mouths of the two were tightly blocked, and an unknown sound came out of their throats. Ran Yu played with the saber in his hand, and his eyes suddenly became fierce: "Don't make a sound!"

Even during the fierce fight just now, Sun Da and Sun Er never saw the young man in front of him show such a severe and terrifying expression.They both froze, not daring to whine anymore.

The world is finally quieter.Ran Yu took out a small radio with whitish edges from his pants pocket, wiped it carefully with the corner of his clothes, turned on the switch, and then sat cross-legged.

A soft and pleasant female voice sounded on the radio: "Dear candidates and friends, good noon, welcome to listen to "Sprint Class for Ideological and Moral Courses for Entrance Examination" on time in the new week. I am your teacher Peier. I will be there tomorrow. Registered, I believe that many friends have fallen into pre-exam anxiety, can't memorize books, knowledge just doesn't enter their brains. It doesn't matter, Teacher Peier will take you to recite the formulas! First of all, let's review the formulas we memorized last week: Human beings are human beings. In a big family, it is not advisable to kill each other. Labor is glorious, robbing and shameful, and building a homeland with the enemy..."

Sun Da and Sun Er looked at each other, covered in cold sweat.The situation in front of them was far beyond their comprehension, but the two of them could not speak or move, so they could only accompany this strange young man to listen to the ideological and moral lessons on the radio.

This listening is a full half an hour.

During this period, the young man nodded thoughtfully while listening to the class, and looked at the two of them from time to time with intriguing eyes.

Sun Da and Sun Er went out of the city to carry out a secret mission, and they were cautious along the way, trying to pretend to be barbaric outsiders who robbed the city as much as possible.The young man probably regarded them as road robbers.

But looking at this young man's skill and behavior, he does not seem to be a soft-hearted person.He chose to tie up the unconscious robber instead of killing them directly, which made them suspicious, worried that the young man must have seen something and was planning some cruel methods.

Sun Da and Sun Er had never experienced this kind of spiritual grievance.This kind of silent moral judgment and vague contempt coercion slowly grind people's nerves like a blunt knife.Coupled with the fact that they couldn't predict what the young man would do next, this feeling of not knowing when death would come made Sun Da extremely annoyed, and he whimpered again.

After listening to Teacher Pei'er's concluding remarks, Ran Yu politely waved to the radio and said, "Goodbye, thank you, Teacher Pei'er." Then, he stabbed Sun Da in the abdomen with the back of a knife, and asked impatiently, "What's the matter?"

Sun Da was almost stabbed and vomited, trying his best to wriggle to show that he had something to say.

Ran Yu pulled out the dirt bag in his mouth, and Sun Da slightly moved his jaw which was nearly dislocated, and said bitterly: "You can kill or cut it up as you like! Don't use such indecent torture on us again. To extract a confession, we would rather die than surrender!"

"What kind of torture method? This is a sprint class from a famous teacher that I finally found. It's cheap for you." Ran Yu carefully put away the radio, stood up, patted the dust on his pants and said, "I've changed my mind and I won't kill you guys." .”

Sun Da's heart fell to the bottom, and he shouted, "Why? What do you want to do?"

Ran Yu raised his head, and the dazzling sunlight that leaked from the forest leaves sprinkled his head and face, adding some noble and holy colors to his originally gentle face.

He said solemnly: "Because I need an immersive test preparation environment to be a moral person."
