Those years of engaging with the system for animal insurance

"Hey! Xueba, how about eating alone?"

Han Yunxi sat down next to Li Cixin familiarly.

Li Cixin ignored him, still eating slowly.

"Hey, do you know how to fight? You held my hand with great strength."

"Are you so cheap about this time, that Jiang-believing one?"

"Do you want me to help you teach him a lesson?"

………………

Li Cixin never thought that a person could be so noisy.

He put down his chopsticks:

"Do you know that you are annoying!"

Han Yunxi: "Don't be like this, make friends, many friends have many paths."

"I'm not interested in anything other than study." Li Cixin finished his last bite of food, took out a tissue to wipe his mouth, got up and left.

"Eh……"

"Brother Xi, why are you sticking your face to someone's cold ass? What's the use of this fat man besides studying well." A younger brother said dissatisfied.

Han Yunxi shook his head pretentiously:

"He is not an ordinary person, his eyes revealed a trace of evil spirit!

The key is that he has great strength, and beating someone will definitely hurt. "

Li Cixin is still studying next, and after returning home from evening self-study, he finally heard the long-lost voice of the system:

"Drip! System task release:

Save the Yangtze River Spirit, the Baiji Dolphin, and go back 30 years.The mission is about to begin, please prepare the host. "

Li Cixin hurriedly washed up, lay down on the bed and started the task.

When he opened his eyes again, all he could see was a vast expanse of water.He himself lay on a sandbar in the middle of a lake.

Looking at his body again, he turned into a creature with fur and sharp claws.

"The host's current body is a mammal - Carnivora - Mustelidae - Otter - Eurasian otter. The location is the Dongting Lake area in the south of China. Is the host undergoing genetic modification?"

It turned out to be an otter, but after looking at his current small body, thinking of the densely populated Yangtze River Basin, Li Cixin opened the panel for safety reasons.

Unexpectedly, after the completion of the last mission, genetic modification unlocked two more, one is giantization and the other is speedization.he asked:

"With the previous power transformation, can the three be used together?"

"Yes, but there are many overlaps between strength transformation and gigantic transformation, and the body weight may exceed expectations."

Li Cixin thought about the power transformation of the green peacock before, which also made the green peacock nearly three times longer and six times heavier.

The Eurasian otter is less than one meter in size, only 60 to 80 centimeters, and the largest is no more than 5 kilograms.Except for the giant otter in South America, which is relatively large, the others are all small.

After thinking about it, it shouldn't have much impact, so the genetic modification started.

The three transformations were carried out together, and Li Cixin passed out before he felt the pain.

When he woke up, it was already the next morning. He looked around and found many small fishes dead on the lake, with white belly, looking very scary.

His first reaction was: Is someone coming to poison the fish?

At this time, the system will say:

"This is the fish killed by the energy of the host's transformation."

Li Cixin "... By the way, how is my current situation, I feel that the surrounding area is quite small."

System: "The three-stage genetic modification of the otter has been completed, with a body length of ten meters and a weight of 2.2 tons!"

Hearing this, Li Cixin gasped, what kind of monster is this?The otter, which was less than one meter long, has been transformed into a ten-meter-long otter, and its weight has changed from 5 kilograms to an astonishing 2.2 tons!

"This genetic change is simply not to the extent that 1 plus 1 equals two. It's too scary. It turns out that these are not small fish. Even the 1.5m to 2.5m baiji dolphin weighing 230 kg is a small fish. It is estimated that the entire Yangtze River Basin He's the biggest."

Li Cixin: "It's okay, it's better to be bigger, it can save my life."

He looked at the clear lake water, moved his body and got into it.

When his whole body was submerged in the lake, he suddenly felt the gravity lighten. It is no wonder that many large animals that live on the water like to stay in the water for many years. Not having to work hard to support their huge size is also one of the reasons.

Especially large reptiles, such as pythons, anacondas, and crocodiles, once out of the water environment for a long time, firstly they are prone to dehydration, and secondly, if the water is too shallow, it is easy to cause huge body weight to oppress the internal organs, which will lead to death in the long run.

Therefore, the survival of organisms is closely related to the environment.

Fortunately, his otter is a mammal, and the evolutionary history of entering the water is not too long, so he will not be crushed to death like a giant crawler, which means that he has considerable freedom of movement in the water and on the shore.This also provided him with excellent conditions to save the baiji dolphin.

At the same time, the system also passed some information to him by the way.

The Dongting Lake where he is now was once the largest freshwater lake in China.In ancient times, there was a saying that Dongting was [-] miles away. Later, in the Qing Dynasty, the rulers encouraged the reclamation of fields around the lake and the reclamation of wasteland.The saying at that time also changed from Su Changshu, Tianxiazu, to Huguangshu, Tianxiazu.

In addition, the over-development of the upper reaches of the Yangtze River and the four river basins in Hunan Province has resulted in serious soil erosion, and a large amount of silt has entered the lake area.Gradually, it retreated to become the second largest freshwater lake.

By the 80s, Dongting Lake had been divided into many lake groups, and it was only later that the farmland was gradually returned to the lake and the silt was treated to improve it.

Dongting Lake used to be one of the main habitats for Baiji dolphins.

Baiji as a cetacean Artiodactyla – under the order of Cetaceans, the genus Baiji in the beaked dolphin family.It's a real mammal.

Because he lives in muddy water all year round, his eyesight and hearing are seriously degraded, and he mainly relies on echolocation to perceive the surrounding environment.

Because of the reduction of habitat; environmental pollution; food reduction due to overfishing; or direct killing of baiji dolphins; and the establishment of various dams on the Yangtze River have blocked their migration.

In the 80s, the number of baiji dolphins was observed to be only about 300.In 1979, Huaxia designated it as an endangered species, and in 83 it was legislated for protection.

In 2002, Qiqi, a baiji raised in captivity, died. In 2004, a dead baiji was found stranded on the banks of the Yangtze River in Jinling. Since then, no one has found a baiji.This creature that has existed in the Yangtze River Basin for 2500 million years also bid farewell to the stage of history.

Baiji dolphins are as intelligent as apes, and they're pretty smart, really.

But no one knows what kind of lonely fear the baiji found in Jinling died of.Although it may have exhausted its strength and used echolocation to find its companions, it is destined to find nothing in the muddy river water mixed with garbage.

There are always people on the Internet expecting that, like other animals that have been declared extinct, they will quietly appear in people's sight one day inadvertently, appearing on the clean and clear river, floating in the waves.

Is this possible?It's unlikely. In fact, we all know that the meeting of such a large aquatic mammal in 04 may be the last time.

Li Cixin felt a little heavy. He also knew a little about the story of this animal population before. Since the task this time is to save them, let's do it.

The reservoir blocks the migration. Even if it is so huge, it is impossible to solve the problem of reinforced concrete. What's more, these dams are related to the safety of hundreds of millions of people in the middle and lower reaches of the Yangtze River. Even according to the conditions of the system, they cannot be moved.

Then we can only start with habitat and food.

Li Cixin wandered at the bottom of the lake, looking at the underwater world, he couldn't help but sigh with emotion at the severe silt accumulation in Dongting Lake.

The depth in many places is less than five or six meters. If there is more silt, he may not be able to hide it.

There are still many schools of fish in these lake areas, most of which are common fish such as grass carp, carp and bream.

Li Cixin slammed his oar-like tail violently, and he fainted, and began to fill his stomach.

He was floating on the water to eat fish, and found that he was already close to the shallows. There was a small house not far away, and there were many ducks in a fence next to it.

Out of curiosity, he walked up to the shore with short legs to see, an old man was sleeping in the house.

So he sneaked along a few duck eggs, causing the ducks to quack.Waking up the duck herder, he quickly got into the water.

After being woken up, the old man stared at the rippling lake surface for a while, then went back to sleep.

At this time, it was already a summer morning, and not far away, many people were breaking bamboo shoots.Li Cixin poked his head out to look at it for a while, then swam north.

All the way north, he felt what the word "broken" meant. He saw a roadblock in front of him. Silt separated the lake into two halves. The 100-meter-long mud embankment in the middle was completely filled with rice. The rice was being pumped for grouting When it was time, it was a piece of green.

If you want to continue north, you must either pass through here or make a detour.

Considering that it takes time to make a detour, if you meet someone in broad daylight, it will probably make a big fuss.After all, no one will be calm when they see such a big thing coming out of the water.

If you walk at night, it is precisely when poisonous snakes come and go, especially in rice fields, and you are not immune to poison.Don't die before leaving the teacher.

However, Li Cixin did not hesitate too much. He stood up with his powerful tail, a full three meters high, and clearly understood the situation around him.

After confirming that no one is there, sprint over as fast as possible.

After diving into the water, he asked the system:

"System, how much time did I just spend?"

System: "165 meters, the host took 9 seconds to complete the crossing."

Li Cixin: "I didn't expect the speed on land to be so fast, what a surprise."

However, looking back at the rice field he just passed, an indentation more than three meters wide made the rice fall down.Like an oversized tire going straight through it.

Li Cixin didn't feel that he had to compensate others. After all, he was just a two-ton otter. How could a little otter be evil?I didn't build fields around lakes either.

Thinking of this, Li Cixin swam his tail up and down and swam north.

It should be in the northern part of Dongting Lake. The lake is much wider, and you can’t see the edge in several directions. At a glance, it is sparkling, and it has the appearance of the water country.

Suddenly, he seemed to hit something!
