I have no pheromones, you smelled wrong

In the interstellar era, landers are often used to explore new planets. According to Lin Xu’s estimation, the size of a lander is close to the size of a large civil aviation airliner before the end of the world. In addition to meeting the functions of normal life, the military lander is also equipped with an arsenal , Aircraft parking library and corresponding defense system.

The No. 309 lander left the Victoria and flew to the earth carrying Lin Xu and others.

The background of the universe is like a thick ink, and the earth illuminated by the sun is interlaced with three colors of blue, white, and emerald green. Through the porthole, the mottled moon floats silently beside the earth.

The upper part of the moon is missing a piece, which is said to have been crashed by the Ark Fleet that fled the earth that year. Countless moon fragments were scattered in the universe, and under the action of the earth's gravity, a ring of small celestial bodies was formed around the earth.

The landers and spaceships flying towards the earth all carefully avoided this ring, and countless flying devices headed towards the earth with tail flames, like thousands of arrows, announcing the arrival of human beings to the earth.

Lin Xu also saw several sturdy spaceships approaching the debris belt cautiously, using their robotic arms to grab debris from the moon and man-made space junk mixed with moon rocks.

They are also precious historical relics.

Looking into the distance, the junction of the earth's curved outline and the universe is wrapped in a layer of quiet blue light arc.

But soon, the space fleet and the debris belt disappeared from the field of vision, the lander entered the atmosphere, accompanied by the sunlight refracted and scattered by the earth's atmosphere, the dark and endless universe was replaced by clouds and blue sky, and human beings seemed to fall into a gentle world at this moment. embrace.

When you look farther away, what you see is the green horizon that is still curved.

The lander is falling at a steady speed, and the AI ​​prompts that the gravity control system in the lander cabin is adjusting the gravity state in the cabin according to the gravity of the earth.

Ryan was left alone in the rest area of ​​the lander. He stuck his nose to the porthole glass and fixed his eyes on the surface. There was unspeakable shock and joy in his eyes, and even his bones were trembling.

In the cab, Arnold and Cassandra were in charge of operating the lander, while Heinrich and Lin Xu stood behind the driver's seat. From the moment the lander was immersed in the earth's atmosphere, no one spoke and looked out the window quietly everything of.

This is the home planet of mankind...

"309 has reached the scheduled cruising altitude." The AI's electronic voice sounded in the cab, and a transparent blue three-dimensional terrain projection appeared above the console, "Currently 6.213 kilometers from the ground, the location is the troposphere, high-precision radar terrain projection Ready, please proceed to the next step."

"Marshal, where are we landing?" Arnold asked.Before entering the earth, Heinrich only gave a rough mountain marker, without further confirming the specific marker location.

Heinrich looked at Lin Xu.

Lin Xu blinked and came back to his senses from the blue. He stepped forward and approached the front window. For Lin Xu, the mountains and rivers of the ancient earth are more familiar than the accurate topographic projection.

The lander is hovering above a piece of verdant land at this moment, the clouds are left behind, looking down, the outline of the land is clearly visible, and the mountains rise and fall like a dragon.

"Southeast, land at the starting point of this mountain range."

The general base of the Doomsday East Region was built on the foothill plain at the southeastern starting point of Kunling Mountains. If this is the earth he once lived on, after 3000 years of human beings’ departure, there should always be some broken walls of old buildings. ruins.

But the lower the height of the lander and the clearer the surface shape, the more Lin Xu felt something was wrong.

The overall outline of the Kunling Mountains is complete, and it is the same as the mountains in Lin Xu's memory, but the topographical outline at the end of the mountains has changed.

"Wait." Lin Xu called to stop the two drivers, and stopped their descent. "I need to remove the terrain contour map of the vegetation on the ground."

Cassandra entered relevant parameters according to Lin Xu's request to change the shape of the terrain projection.Marshal Chu's operation was private. Cassandra didn't know what Heinrich wanted to come to Earth to find, and he didn't understand why he brought Lin Xu with him and asked Lin Xu to guide him.

But she knows how to obey all the instructions of her boss.

Four seconds later, a new projection map appeared, and Lin Xu's brows gradually frowned as he glanced over the projection.

...The topographic outline at the end of the mountain range has indeed changed, and a large sunken pit appeared at the location of the base in memory, with an estimated diameter of about [-] kilometers.

Lin Xu pointed out the location of the huge crater, "Land down here."

"Dr. Lin, this is a lake." Cassandra called up the infrared temperature-sensing imaging topographic map, and the temperature where the giant crater is located is significantly lower than the surrounding area. "The impact force of the lander's jet may affect the water balance of the lake. , leading to the destruction of lake organisms."

But there has never been such a large lake at the end of Kunling Mountains.

Lin Xu was a little confused. Could it be that the marker of the general base that Heinrich picked up in the Kuiper belt was really just a coincidence?

"Land down nearby." Heinrich supported Lin Xu's shoulder and added for him, "After landing, drive another aircraft closer."

Cassandra and Arnold found an open and geologically stable area in the nearby mid-mountain to land the aircraft. With a burst of metal tremors and billowing smoke and dust, they finally set foot on the land of the earth.

Before leaving the cabin, you need to put on an isolation suit and a powered exoskeleton.

The cutting system of the black isolation suit is basically the same as that of the combat uniform, except that the combat uniform with separate clothes and pants is changed to a one-piece style, the gloves are also connected to the cuffs, and the trousers are tightly bound in the boots.

Among the two non-professionals, although Ryan has not been to a military academy, he has been with his general father for so many years and has been trained to be able to wear various uniforms in the army.

Only Lin Xu had never been in contact with military uniforms before—not counting the military uniforms he used to build his nest. Heinrich worried that he would not know how to operate the isolation suit and powered exoskeleton, so he took the initiative to knock on Lin Xu's changing clothes room to help.

Lin Xu seemed to see that Heinrich had ulterior motives, so he smiled, but did not refuse.

The buckle of the isolation suit was on the back. Heinrich helped Lin Xu close the isolation suit bit by bit. The pale back with scars was covered by the black isolation suit until the nape of the neck.

Heinrich lifted Lin Xu's long hair, and pressed the hidden button at the last moment. Lin Xu turned around, but was pushed back to the seat by Heinrich's shoulders. He was a little puzzled, and Heinrich went around Behind Lin Xu, five fingers inserted into Lin Xu's black hair, and he combed it slowly.

After combing the long hair, Heinrich unskillfully divided the long hair into three locks, and braided them into a braid behind Lin Xu's back.

Lin Xu touched it with his backhand, and saw Heinrich squatting down in front of him, taking the combat boots and preparing to put them on for Lin Xu.

"I'll do it myself." He wasn't spoiled enough to need someone to help him put on his shoes.

But Heinrich held Lin Xu's ankles silently, put on combat boots for him, tucked all the trousers into the boots, and finally tied the shoelaces.

After finishing all this, Heinrich did not get up in a hurry, but looked up at Lin Xu. Lin Xu raised his eyes, and his scattered eyes focused, meeting Heinrich's eyes.

Heinrich put his hands on Lin Xu's knees, and when he raised his head, his high eyebrows no longer hindered the light, and his sharp golden eyes were fully presented in front of Lin Xu, "What are you worried about. "

Heinrich used a declarative sentence.

This gradually dissipated the remaining smile on Lin Xu's face.

Heinrich knew that Lin Xu didn't smile often, and even if he made this expression occasionally, it was usually for others to see. For example, when Heinrich walked into the locker room just now, his slightly teasing chuckle, But the inner thoughts are always hidden.

"I..." Lin Xu hesitated again when he spoke.

He never told anyone about his past, not even Heinrich.It's not just that he didn't say it, but when his consciousness was connected, Lin Xu was very sober and tenaciously closed his spiritual domain, not revealing a single trace.

But when they came to the ancient earth, what they were looking for was the past.

Now, the giant pit is like Schrödinger's cat. There may or may not be a doomsday base there.If not, Lin Xu would be as empty as duckweed in this world, but if there was, he would have to think about what happened in the end-time base after he tore apart time and space and left.

After all, it is impossible for the Ark fleet that set sail to find a new home to take away all the survivors on the ancient earth.

Lin Xu twitched the corner of his mouth, "I will tell you when I have the answer."

Heinrich respected Lin Xu's opinion as usual, and did not pursue further questions. He reached out and touched the back of Lin Xu's hand in the isolation glove, pulled him to stand up, and pressed the button on the side of the stand-up collar of the isolation suit.

A light-transmitting film extends upwards from the stand-up collar, outlines along the bones, skin and hair, and covers all exposed parts of the human body.

Isolation suits are used to prevent direct contact between landing humans and the earth's environment. After all, no one can tell whether humans returning to Earth after 3000 years will carry deadly space germs, or whether the earth has evolved some kind of virus that can easily kill humans. Super virus, this suit also has a certain temperature control function.

But on the issue of isolating radiation, this isolation suit is lackluster.

Measurements by the advance unmanned probe show that the current radiation level in the earth's environment is [-] millisieverts per hour, which is one-tenth of the normal radiation value of Capital Star, and no special protective procedures are required for people leaving the cabin.

Only Lin Xu knew that this was almost [-] times the amount of radiation in the earth's environment before the end of the world.

However, the quality of human beings entering the interstellar era has been strengthened in all aspects, including the ability to withstand various radiations, and they can live and dance in this radiation environment that can kill humans on the ancient earth.

Otherwise, Ika, who ran into the scene of the black hole explosion, would not be as simple as having radiation damage on the skin of his body.

The outer layer of the isolation suit is a powered exoskeleton to assist the lander in high-intensity exercise.

After putting on everything, Heinrich and Lin Xu will drive the aircraft to the location of the lake. Cassandra and Arnold stay on the lander and check the surrounding environment. Ryan is allowed to go out of the cabin and walk around the lander.

Taking off from the middle of the mountain, the sky is blue and the eyes are green. The tall and various trees are gently swaying their branches in the mountain wind. The birds in the mountains are startled by the noise of the aircraft and flap their wings to escape.

Heinrich even saw a horned four-hoofed animal scurrying through the jungle, hiding behind a stone, watching the strangely shaped monster in the sky with moist innocent brown eyes.

"what is that?"

Lin Xu took a look, "Deer, sika deer."

In the past, the environment near the doomsday base was not so good.

The surrounding fields of the base have been completely emptied, and the cement or asphalt roads extending in all directions are covered with roadblocks to isolate the zombies from approaching. The checkpoints will only be opened when the action team enters and exits.

A large number of trees were cut down for fuel, scattered in the wilderness, and humans who were unwilling to enter the base for control had to rely on hunting for food after exhausting the supplies left over from the civilization era, but this strategy did not last long .

Pollution, mutation, and long winter have killed a large number of animals and plants, and human beings have to huddle alone in reinforced concrete.

But the last days were not natural disasters from the beginning.

Otherwise, if what you need to face is only body-enhanced, contagious, and human-eating zombies, the thermal weapon technology of modern civilization can easily kill all disasters at the time of birth.

Lin Xu also vaguely mentioned that at the beginning of the end of the world, various rumors about the zombie virus were rampant, such as the theory of divine descent, the theory of aliens, and the theory of evolution... He listened to these rumors, but he couldn't determine the real source.

Until he walked up step by step and opened the secret information that all those who knew the inside were silent about.
