When Chen Yingying returned to the gathering place, it was almost dark, and when he walked outside the valley, he saw the already high wall and the people waiting anxiously under the wall. Pen, fun, pavilion www. biquge。 info

"Uncle!" The little girl threw herself into his arms.

"The progress of this wall is very fast, Lao Wang, it seems that you have contributed a lot." Chen Yingying tapped it with his hand. The labor is very solid, and it is all concrete mixed with stones.

"Boss, these girls work very hard, the cement is enough, and Lao Fu helped get a lot of explosives to blow up stones, so they can do it so quickly."

"Not bad, not bad." Chen Yingying looked around the wall.

Wang Fugui did put a lot of thought into it. The wall is 15 meters high and more than two meters thick, and except for a doorway for trucks to enter and exit, all the other places have blocked the gap in front of the valley more than 100 meters.

This is no longer called a wall, and it is not an exaggeration to call it a city wall.

"Actually, I originally meant to blow up the mountains on both sides of the valley, and the earthwork pushed down directly blocked the gap in front of the valley, leaving only a tunnel in and out. But Lao Fu didn't do it and refused to make too much explosives. Wang Fugui complained.

"Damn! This idea is really fanciful enough, but the amount of work is too large, even if there are so many explosives, where can there be so many manpower and time? Chen Yingying thought to himself.

"By the way, what about Lao Fu?"

"Lao Fu? When he saw the mutated zombies you brought back, he went headlong into the lab, and said that whoever wanted to disturb him, he would blow them up to the sky. Wang Fugui pursed his lips and said.

Chen Yingying raised his feet and rushed to the laboratory, he had a lot of questions that he wanted to figure out as soon as possible, and the shock that those two mutant giant beasts brought him today was too great.

When he walked to the front of the laboratory and pushed the door, the door was locked from the inside, Chen Yingying knocked a few times, but no one answered at all.

Chen Yingying lifted it with a kick, and there was a loud "boom", and the entire gate was torn apart.

"Momfuck! Who! Who is it! Fu Tiantian, who was busy on the workbench, was startled and rushed out brandishing a scalpel.

After seeing that the person outside the door was Chen Yingying, Lao Fu's face suddenly wilted: "Hero, why don't you knock on the door?" ”

"I knocked it, but no one answered."

"This is? What you got from today's mutants? Show me! Fu Tiantian's eyes were very poisonous, and at a glance, he saw the sickle that Chen Yingying was carrying on his shoulder, and as soon as he rushed over, he was ready to rob it.

"Don't worry, Lao Fu, I'll give it to you, but I have something to ask you, let's go into the house and say."

Walk inside the house。。。。。。。

"Lao Fu, judging from your research during this time, is it normal to evolve such a big mutant beast?"

"Recently I found another interesting phenomenon, do you know what it is?" Fu Yitian sold a pass, said.

"What phenomenon? Does it have anything to do with mutants? ”

"Don't you notice that the air is cleaner now than it used to be?"

"Well, there is, isn't this because the factories have been shut down in the last days, and there is no pollution?"

"That's one thing, but not the main reason. The most important reason is - the amount of oxygen in the air has increased. ”

"Does the amount of oxygen have anything to do with the mutant beast?" Chen Yingying was puzzled.

"Of course!"

As soon as Fu Yitian mentioned his research, he immediately became excited: "Because only when the oxygen content is high, organisms do not need to increase the volume of the respiratory system to provide more oxygen for the enlarged body size, and the limiting influence of the respiratory system on body size is reduced, and organisms will naturally be allowed to develop towards a larger body size!" ”

"This... This one... Lao Fu, can you put it simply? You know I used to be a scumbag, I don't understand these things. ”

Chen Yingying's face was dull, and his eyes were full of Teletubbies-like blankness.

"Well, I'll keep it simple, you know the Carboniferous and Jurassic. The creatures that lived in these two epochs were huge, such as dragonflies that were 3 meters long, centipedes that were more than 10 meters long, and dinosaurs, which people were most familiar with. ”

"You're saying it all has to do with the amount of oxygen in the air?"

"Of course! Do you know what the amount of oxygen in the air was in these two epochs? That's 30 percent in the air right now! Or even higher! ”

"Does that mean it won't be long before the Earth returns to the Jurassic era? Will there be a dinosaur Luo? ”

"Of course not, extinct species will never reappear, but existing animals will begin to evolve, just like the giant mutants you see today."

"I'll be a good girl!" The thought of living in a world full of giant beasts in the future, Chen Yingying's heart trembled.

"Of course, some things are not necessarily absolute, the evolution of super life is very complex, some can be, and some will be gradually phased out. I need to study these again. Fu Tiantian pushed his glasses and said.

"Are those two mutant beasts coming to attack us today?" Chen Yingying asked the question he was most worried about.

"Absolutely not, a creature of this size requires a huge amount of energy to hunt every time, and if the food caught is too small, it is not cost-effective for them. Have you ever seen a lion eat a sheep and a cow, but have you ever seen a lion eat worms? For them, we are bugs, not on its recipe at all. ”

"Oh, that's it, then I'm relieved, but what happened to the army last time? How did you get involved with the mutant beasts? ”

"It's possible that you took the initiative to provoke it, or it could be that the mutant beast has just evolved and is not so huge. One or two sparrows can only be stuffed between their teeth, but if there are a few more, they can barely eat. ”

"I know, I will tell them that if they encounter it in the future, they can't take the initiative to do it, they can only walk around."

"Alright, give me the materials, I'm going to get to work." After Fu Yitian finished speaking, he wanted to take the sickle in Chen Yingying's hand.

"Wait!" Chen Yingying turned around and carried the scythe behind his back.

"What's wrong?"

"Lao Fu, don't take you like this, you haven't paid it last time, you can't play blank this time."

"And what do you want?" Fu Yitian frowned.

"Give me another 500 of your bombs, give me 50 pounds of explosives, what materials do you need, you say, I'll help you find them!" Chen Yingying opened his mouth widely, and a lion opened his mouth.

"No! Where do I have the time to waste on these boring things! Hearing Chen Yingying's price, Fu Yitian almost jumped up.

"How can this be considered boring? Lao Fu, think about it, if our strength can't be improved, how can we help you find more advanced materials and mutant zombies? You're doing yourself a favor! Do you understand? "Chen Yingying is like a bad boy who is ready to abduct an ignorant girl, and he is kind and seducing.

"Well, I'll take some time out in the next few days. Forget about explosives and bombs, it's too time-consuming, anyway, you have a lot of arms now, it's not bad for me, I'll get you something else. Fu Tiantian thought for a moment and said.

"Well, that's it. Hello, this is for you. Chen Yingying took out a bottle of white giant tiger blood from his bag and handed it to Fu Tiantian.

"What is this? I want that arthropod in your hand, what are you giving me a bottle of blood for? ”

"I can't give you this arthropod for the time being, I need this as a weapon. This vial of blood was obtained from another giant beast, so it should be more valuable for research. ”

"Really?" Fu Yitian's eyes lit up immediately.
