As the sun set and the people feared that the giant insects would appear again at night, and other problems would arise, the two boats, laden with honeydew and grain, quickly sailed away from the frightening island.

After Zhang Xiaohu returned to the boat, he went to Li Yichen's room again, knocked on the door for a long time, and there was no response inside, he was in a hurry, and he didn't have so many scruples, so he knocked open the wooden door and found that Li Yichen was just sitting on a chair in the room, holding a pen in his hand and not knowing what he was writing. As soon as he saw Zhang Xiaohu breaking in, Yichen's face changed, and he had a somewhat angry expression, and blamed: "Senior, can a girl's room break into such a barbaric way?" ”

Yichen's face is not bad, but at first glance, he hasn't taken care of himself for a long time, and he hasn't seen him for two or three days, his originally beautiful hair is scattered, and his delicate face is a little puffy.

"I've been calling you outside for a long time, and you haven't responded, I'm worried that something will happen to you!" Zhang Xiaohu hurriedly argued, in fact, he hadn't seen Yichen for a few days, and it just so happened that this time he had a reluctant reason to give him the courage to break in.

"What's wrong, why are you worried about me?" It seems that Li Yichen has no idea what is going on outside, not even what happened last night.

"What happened to you last night, you didn't hear the alarm! Don't know what's going on out there? Zhang Xiaohu was a little surprised, he rang the bell for the guard last night, and even the people on the Goddess heard the alarm, Yichen didn't know what was going on, it was too strange.

Seeing Zhang Xiaohu's strange expression, Yichen took out a beautiful glass bottle from his pocket and said, "This is another potion for me, the name is "Sleeping Beauty!" "She knew that I might be preoccupied and not have a good rest after we met, so she gave me this, and when I can't sleep, I can sleep well for the day with a sip, and I won't wake up during that time, no matter what happens around me. I took a sip early yesterday morning and woke up at noon today, and I really don't know what's going on outside! ”

Zhang Xiaohu realized that it was no wonder that Chenyi had rarely gone out recently, and it turned out that there were these reasons. He hesitated for a moment, and told Yichen about the things that happened on Worm Island last night, including everyone's experience in the anthill today, and saw Yichen's nervous and sad appearance for a while, he knew that it seemed that after a few days, it seemed that Yichen's mood had improved a lot. But he was still very strange, why didn't Yichen open the door for himself just now, she woke up early tomorrow, why didn't she ignore herself, it seems that there are other questions here, he must ask to understand. He asked, "Why didn't you open the door for me just now?" ”

Speaking of this, Yichen suddenly realized something, and immediately got up and covered his face with one hand, and pushed Zhang Xiaohu out of the room with the other, and complained in his mouth: "Senior, you are so annoying, I don't want to see you anymore!" ”

Zhang Xiaohu was pushed out of the door with a blank face, completely unaware of what was happening.

Yichen's voice came from the room, "Senior, I'm fine, don't worry about me, I... I don't see you because I'm now... It's ugly now! I've been sleeping a little too much lately and my face is a little swollen, and when I recover, I'll go to you! ”

Zhang Xiaohu was relieved at this time, and he was about to turn around and leave with a smile on his face. At this time, King Peter actually came over, saw Zhang Xiaohu, and hurriedly said: "Boy, I just saw you, come and do me a favor!" ”

King Peter took Zhang Xiaohu to his room, and Zhang Xiaohu saw that there was a corpse of a soldier ant and three insect cocoons in the room, and he really didn't know when King Peter got these things back.

King Peter needs an assistant, when he is dissecting the soldier ants, he needs to hold the lights in his hands, illumination, he has already found a few people, everyone is scared away when they see the corpse of this soldier ants, if he doesn't meet Zhang Xiaohu, he is ready to give up tonight's research, can only wait for tomorrow when the sun is full of light.

Zhang Xiaohu felt that he was fine anyway, so it was better to help him with this, and today in the anthill, thanks to King Peter's expertise, everyone was saved from a lot of danger.

When King Peter was studying, it was as if he had become a different person, his eyes revealed concentration, and his hands skillfully operated in the body of the soldier ants, dividing and sorting out the organs one by one and storing them in good condition. I don't know that he got a lot of glassware there, and there are a lot of clear liquids in them.

After some busyness, King Peter took a long breath, looked at Zhang Xiaohu, and said, "Okay, boy, thank you, you did a good job!" ”

Zhang Xiaohu smiled slightly and replied, "Why don't we go out together to get some air!" ”

At night, the sea is filled with a little phosphorescence, and the moonlight shines on the seawater, which makes the deep sea water a little more mysterious.

Zhang Xiaohu and King Peter sat on the deck, Zhang Xiaohu looked at King Peter, the man who had once advocated giving up on himself, and a tolerant smile appeared on his face, and only then did he really forgive this man. The more he comes into contact with everyone, the more he can feel everyone's wonderful life, and he feels that although the people in front of him are a little too realistic, rational, and even a little selfish, but several times in the face of major rights and wrongs, he shows profound knowledge and rationality, which several of them lack.

Maybe this is the manifestation of human evolution in the future, natural selection, survival of the fittest, in the face of many realities, only rational and scientific enough to analyze the problem, in order to solve the difficulties encountered in life, when everyone can do this, social progress can be reflected.

Now Zhang Xiaohu actually admires King Peter, he has a lot to learn, he is now a core member of the team, constantly providing scientific technical support for everyone, and has also been recognized and trusted by everyone.

He had a question in his heart today, and he took this opportunity to ask King Peter's opinion, and he wondered, "I am thinking about something, I want to ask you, to see if you can help me?" ”

"Let's talk about it, I don't have much contact with other aspects other than this knowledge of biology!" King Peter was honest enough to explain his expertise first.

Zhang Xiaohu smiled: "In this way, this question is really only you can help me answer." Today I recalled, from the time we encountered the storm, and after that we encountered some giant creatures, could it be that there is something different in this sea? Could it be that there are any irritating substances in the seawater? You're a biology expert, so you should know a little bit about that! ”

King Peter laughed, "Haha! Brat! You're thinking too much! Where to go for an extra boost! Many organisms have a process of changing from large to small in the process of evolution, such as the giant dragonfly in ancient times, which can reach two or three meters in length, but after hundreds of millions of years of evolution, the largest of its offspring is only a dozen centimeters long, the key to this is that the oxygen content in the air has changed, and the huge body needs more energy and oxygen, and when the oxygen content cannot meet the demand, it will..."King Peter covered his neck and made a look of not being able to breathe.

"So will there be any effect on our long-term exposure to this high-oxygen environment?" Zhang Xiaohu was most worried about this, he recalled it well, and found that the creatures in this world seemed to be huge. If it is because of the increase in the oxygen content in the air, according to King Peter, whether these people will also be affected and changed unconsciously, it is just that everyone has not yet noticed.

"It's okay for the time being, but if you survive in this environment for a long time, it will definitely have a big impact. I will start with the importance of oxygen to living beings, oxygen is an important part of the internal circulation of the biological body, living organisms need oxygen to regulate the carbon and oxygen balance in the body, if the oxygen content in the atmosphere increases, then the more energy the organism can get from the atmosphere, the size of the organism will begin to slowly become larger, but once the critical value of oxygen content is reached, that is, after the oxygen exceeds 35%, the mammals will die in large numbers, this is because the oxygen concentration in the air is too high, resulting in the carbon and oxygen in the body can not be balanced, So there is oxygen poisoning. But the increase in oxygen has no effect on plants and insects, plants will produce more light and action because of the increase in oxygen, a grass may grow taller than a person, and insects because of the use of trachea to absorb oxygen, and the exoskeleton is strong, so the volume of insects will become larger and larger, maybe a dragonfly is the size of a tiger, in fact, this situation has appeared on the earth, in the Carboniferous period 300 million years ago, it belongs to the era of insects, scientists call it "giant insect age", At that time, insects were at the top of the food chain, and mammals were food for insects! Peter Wang gushed about it, this field is exactly the part that Zhang Xiaohu is very unfamiliar with.

Zhang Xiaohu showed a look of sudden realization and sighed: "No wonder the two islands we passed through only have plants and insects, and we can't see other creatures, maybe they have been digested by these insects, or they can't stand the extinction of this high-oxygen environment." ”

King Peter pondered for a moment and nodded, "I think there is actually another possibility?" ”
