National destiny survival: I am weak and rely on luck to fly

Shen Nan expressed his gratitude to Sun Yu, and then Sun Yu sent several messages in succession.

These messages mainly describe a series of recent emergencies:

Many level three and four mutants began to appear frequently and launched fierce attacks on multiple small shelters, resulting in the breach and fall of many shelters.

Even the Chuanzhou Shelter is currently facing a huge threat, as a level five mutant is leading dozens of level three and four mutants to besiege it.

Due to the critical situation, the Chuanzhou Shelter can no longer dispatch personnel to support other small shelters, and they themselves are in a survival crisis.

The only good news is that Sun Yu successfully resolved the crisis facing the Nagasaki shelter again.

At present, Sun Hongbo has completely stepped down and handed over all management rights of the shelter to Sun Yu, who is now fully responsible for the operation and decision-making of the entire shelter.

Sun Hongbo's trust in Sun Yu also reached 100%, and he also received interstellar passes as a system reward, which made Sun Yu very happy.

When Shen Nan heard Sun Yu say that many small shelters had fallen, he suddenly felt nervous.

After congratulating Sun Yu, he quickly opened the light curtain, eager to learn about the current living conditions of the indigenous people of Earth.

[Side Quest: Survival of the Human Race on Earth / (I changed the total population here. It was over 20 million before, but this time it was over billion. The reason is that there are too many words. Please see the author's comments.)

For every 10% decrease in the number of surviving humans on Earth, the number of interstellar passes that survivors can obtain will decrease by 10%]

When they first arrived on Earth, the total surviving indigenous population was more than 23 billion.

After defeating the octopus, Shen Nan checked again and found that the population had dropped to about 22 billion.

What shocked Shen Nan was that in the past two months, the population of Earth had only decreased by 8 million.

It has been less than half a month since they defeated the octopus, and the population has dropped by another 1 million.

Are these mutants crazy?!

For every 10% decrease in the number of survivors on Earth, the number of interstellar passes the survivors receive will decrease by 10%.

Now, the death toll on Earth has decreased by 2.6 million, accounting for about 12% of the total population.

Shen Nan felt heartbroken when he thought that the interstellar pass he had worked so hard to earn would be deducted 10% or even more during settlement.

Xiao Feifei comforted Shen Nan softly: "It's okay, we have tried our best. Facing so many people, we can't do anything. The most important thing now is to complete the task as soon as possible and strive for an early settlement, so that the losses can be reduced."

Shen Nan nodded dejectedly, "Yeah, I understand." There was a hint of helplessness in his voice.

Ren Linhe frowned and said uncertainly: "If there are still people who can come in and out freely here, then it is hard to say whether the virus fluid is still stored here."

His words made the team members realize the seriousness of the situation.

Everyone believes that the original virus liquid is in the Amena Research Institute because this is where the "frozen creatures" were originally stored and it is also the first place to be conquered by the virus.

Therefore, all information and items related to the "frozen creatures" may still be here and have not been transferred.

However, Du Mengyao's appearance suggests that some people can still enter and exit freely here, which means that the virus stock may have been transferred or is still stored in an unknown place.

Xiao Feifei suggested: "Then let's look around first. If we can't find it, we can try to find new clues."

Ren Linhe nodded: "During the search, pay attention to whether there are any hidden passages. If there are, at least we can find other locations through the passages."

They are now on the third floor below ground in the basement. Surrounded by layers of advanced mutants, there are only two possibilities for these people to be able to bring Du Mengyao to the core area for experiments.

The first is that these people can enter the core area quietly while being surrounded by layers of high-level mutants.

The second possibility is that there must be another passage in the core area connecting to the outside of the institute.

Of these two situations, the first one is almost impossible. Even if these people can do it, a large number of survivors enter the periphery of the institute every day. If there is a large-scale in and out activity, it is impossible that no one will notice it.

Therefore, there must be a secret passage here.

Ren Linhe glanced at the light screen and saw messages from Wang Peixiang popping up one after another.

He made a quick decision: "I'll take Nan Nan with me, and you two will act separately and hurry up to search."

They have already wasted half an hour here. Survivors from countries such as the Bald Eagle are gradually approaching the core area. Time is running out.

"it is good."

"understood."

After responding, Shen Wansan and Xiao Feifei went to different laboratories.

This time, Shen Nan did not follow Ren Linhe closely as usual, but chose to walk to the laboratory next to Ren Linhe, preparing to explore there.

Ren Linhe warned seriously: "Be careful and don't go too far."

"I know." Shen Nan replied.

The distance between the two laboratories is not far, only a dozen meters.

Shen Nan believed in himself. Even if he encountered an emergency, with his current abilities, even if he could not defeat his opponent, at least he would have no problem escaping.

He was confident that he could hold on until Ren Linhe came to help.

Shen Nan gently pushed the door open, looked around, and found that this was an experimental space specially used for animal specimens.

There are sixty or seventy different animal specimens on display, with a wide variety of species and sizes.

From tiny insects to giant mammals, both aquatic and terrestrial creatures are represented here.

However, these specimens are not complete. Various parts of their bodies are missing to varying degrees. Some are missing limbs, some are missing some internal organs, and some are even left with only skeletons.

Shen Nan looked carefully one by one to see if there were any limbs of the "frozen creature".

At this moment, the little fur ball suddenly came out from its exclusive space.

The little ball of fur started whimpering as soon as it came out, with its big eyes full of signs of hunger.

Shen Nan immediately understood what the little ball of fur needed. With a helpless look, he took out a bag of biscuits from his space backpack and handed it to the little ball of fur.

The little ball of fur was not picky about food. He happily took the biscuit, jumped onto a laboratory table and started eating it with relish.

Shen Nan continued searching, hoping to find samples related to "frozen creatures" among these specimens.

However, just when the little fur ball was eating happily, a mutant mouse suddenly appeared, jumped over and snatched the biscuit in front of the little fur ball.

The little fur ball, without any guard, stared blankly at the empty biscuit bag in front of him.

“Boo! Boo! Boo!!”

Faced with the little fur ball's anger, the mutant mouse just stared greedily at the snatched biscuits, and then ate them voraciously, completely ignoring the little fur ball's anger.

Shen Nan heard the scream from the little fur ball and quickly turned his head, only to notice a mutant rat of unusually large size.

This mouse is at least ten times larger than an ordinary mouse, and it is chewing on biscuits with its sharp teeth.

Faced with this sudden mutant rat, Shen Nan was not afraid.

His first reaction was that if he killed this mutant rat, he would get a lot of mutant rat meat...

When Shen Nan was hesitating whether to take action to kill the mouse, he looked up and found Ren Linhe standing at the door of the laboratory.

Ren Linhe approached silently, his eyes fell on the mutant mouse, and then he said softly: "Don't disturb it, is there any food? Keep feeding it."

Ren Linhe was curious about the unexpected appearance of non-experimental white mice in such a place. He wanted to know where the cave of this mutant mouse was hidden and whether it could be related to the hidden passage he wanted to find.

Therefore, he instructed Shen Nan to continue feeding the mutant rat, hoping that this method could lead the rat out of its hiding place.

Shen Nan nodded. Although he didn't understand why he had to continue feeding the mutant mouse, Shen Nan was a good and obedient child. He then took out some snacks and biscuits from his space backpack and gently threw them to the location of the mutant mouse.

The mutant mouse initially remained vigilant about the newly appeared food for more than ten seconds, then quickly grabbed the snack with its claws.

And he was extremely smart and used his teeth to tear open the package before starting to enjoy the food.

After a few minutes, the mutant mouse was full.

It noticed that there was still some food left and glanced at Shen Nan and Ren Linhe who were standing not far away, as if assessing whether they posed a threat.

After confirming it was safe, it picked up the remaining snacks with its mouth, quickly ran towards the laboratory door, and disappeared outside.

"Follow him." Ren Linhe said concisely.

Shen Nan and Ren Linhe followed the mutant rat and came to the end of a hidden corridor.

The mutant rat nimbly burrowed into a hole in the ground in front of them and quickly disappeared from sight.

Ren Linhe squatted down beside the hole and carefully examined the surrounding marble floors, tapping gently on each one and listening to the sounds they made.

After noticing that the sound of one marble floor was different from the others, Ren Linhe said slowly, "There might be a hidden passage underneath."

After saying that, Ren Linhe took out a pickaxe from his space backpack and started digging.

This iron pickaxe produced by the system was very strong. Even the thick marble was quickly dug out by him, revealing a big hole.

As the entrance of the cave expanded, Shen Nan saw that there was indeed a narrow tunnel underneath, only wide enough for one person to pass through.

The inside of the tunnel was pitch black. Shen Nan asked worriedly, "This tunnel is so narrow, and we don't know where it leads to. Is there any danger?"

Ren Linhe pondered for a while, and then decided to go down and investigate in person: "You send a message to Shen Wansan and Xiao Feifei, and ask them to come over. I will go down and check the situation first." Before he finished speaking, he had jumped into the tunnel and disappeared from Shen Nan's sight.
