In the shop, the old man watched Chu Yuntian pick up the wing bone and said, "Do you know anything about paleontology?" ”

Chu Yuntian looked at it for a moment, put down his bones, shook his head and said, "I'm sorry, I used to study medicine and didn't have much research on biology. ”

The old man smiled, sat on a chair next to him, and said, "Young man, what do you think is the difference between the current earth and the ancient earth?" ”

Chu Yuntian thought for a moment and said, "There should still be a big difference, the current air and the natural environment are different." ”

The old man looked at him and said, "Then why do you think the current creatures are all growing so big?" ”

Chu Yuntian shook his head and guessed: "Maybe it's a change in the environment, or it's related to that fog." ”

The old man nodded appreciatively and said, "That's right, it's not right." In fact, about 200 million years ago, between the Carboniferous and Jurassic periods, there was a period of time when organisms also grew particularly huge, and after previous scientific identification, the environment at that time was all tropical climate, and the oxygen content in the air was about 1.5 times that of now, so the size of the organisms became so large. ”

Chu Yuntian said suspiciously: "You mean that the oxygen content of the earth's air is also increasing sharply now?" ”

The old man smiled and said, "Although the oxygen content in the air has increased a lot now, it is still far from the Carboniferous and Jurassic periods. I had suspected one thing before, and that was that such a large size was a little unjustifiable simply because of the increased oxygen levels, until I found this bone, which was a bone, not a fossil. ”

Chu Yuntian was shocked and picked up the wing bone again and said, "You said that at this time, a bone of the Wind God Pterodactyl is not a fossil?" ”

The old man nodded and said: "I suspect that ancient creatures have appeared again in some places on the earth, I don't know if they are atavistic creatures, or they ran out of somewhere, but what is certain is that they are also advancing, and the speed of advancement is much faster than the current creatures." ”

"And where did you get this bone from?" Chu Yuntian asked puzzled.

The old man touched the bone and said: "This is when the fog in the sky has just dissipated, I took the plane of the army, went to the beach to patrol, and saw it on a cliff, but there is only this one left, I don't know if I fell off the cliff, or was eaten by something." ”

Chu Yuntian became more and more puzzled, what did these have to do with him, and what did they have to do with his pets, and immediately asked, "Old man, what do these have to do with me?" What does it have to do with my pet? ”

The old man smiled and didn't answer, but instead said, "If my guess is correct, the wing bones should be left behind after the death of a sixth-order pterosaur, don't you want to?" ”

Chu Yuntian was surprised: "Sixth Order? But what's the use of that? ”

The old man patted Chu Yuntian and said, "The bones of the sixth-order creatures, you can go to Fat Chen to give you an imaginary way to make a biological weapon, and when you know its power, you will understand what it is for." ”

"Do you know Fat Chen?" This old man's shock to Chu Yuntian became more and more, and he couldn't help but use honorifics.

The old man smiled and said, "I recruited him from Stone City. ”

Chu Yuntian was shocked: "You are the dean of the scientific research academy?" ”

The old man nodded and said, "The fat man told me about you, if you want, I can give you a spare job, here, as long as you don't want to, no one can force you." ”

"Then why are you here? And why did you give me this Aeolian pterosaur wing bone? Chu Yuntian asked one after another.

The old man smiled and said, "This place is mine, is it strange to appear here?" As for this wing bone, I want you to do me a favor. ”

Chu Yuntian nodded and said, "What do you want me to help with?" ”

The old man stood up and said, "When your pet can carry people, help me go to the beach to see if there are indeed ancient creatures over there." ”

"Okay, if I can, I'll help you take a look." Chu Yuntian nodded and said.

The old man smiled and said, "Okay, tomorrow let Fat Chen bring you a document, sign it, and then you will be a researcher of the scientific research institute." ”

"Thank you, Dean, I don't know what you call it?" Chu Yuntian said politely.

The old man stood up and said, "Just call me Dean Lu, just take this wing bone and go back if it's okay" After speaking, he walked back to the back of the counter, sat on the chair and continued to look at the yellowed book.

Chu Yuntian stepped forward and picked up the thick wing bone, and said respectfully, "Okay, then the junior will go first." After a while, seeing that the old man didn't mean to speak, he turned around and walked out of the bioenergy exchange office with the second daughter.

As soon as she walked out, Xiao Ya hurriedly said: "This is the dean that the fat man said, he is quite polite, and he will give us a big bone as soon as we meet." After speaking, he took Chu Yuntian's injured wing bone.

Chu Yuntian said with some concern: "I'm afraid this is not a good thing." ”

Duo'er asked suspiciously, "What's wrong?" Isn't that good, I gave things before I did anything. ”

Chu Yuntian sighed and said: "Hey, the more he is like this, it proves that the more important Xiao Hei is, the more important he is, the more people he covets, and the more people he covets, the more troubles he has." With that, he walked towards home.

The two girls looked at each other suspiciously, and then followed.

As soon as he walked downstairs, he met the fat man who had just come back from outside, and when the fat man saw Chu Yuntian and the three of them, he immediately walked a few steps quickly and said hello: "Brother Chu, what are you doing?" ”

Chu Yuntian smiled and said, "It's nothing, I went to exchange some first-order energy beads, and I met your dean." ”

The fat man was slightly surprised: "You have met our dean?" What did he say? ”

Chu Yuntian took the wing bone and said, "I didn't say anything, he gave me a bone, and said that I would do me a favor." ”

The fat man took the bone, looked at it and said, "What is this?" Bone? ”

"Your dean said that the bones of the sixth-order wind god pterosaur at this time, and also said that you have a way to make it into a biological weapon." Chu Yuntian said.

The fat man widened his eyes and said, "What? Sixth-order? Also, I've studied the modification of biological weapons, but I haven't made them yet. ”

Chu Yuntian said thoughtfully: "That may be what your dean wants you to study more deeply." ”

The fat man thought for a while and nodded, "Well, it should be possible, but it will take some time, let's go back and talk about it first." After saying that, he took the lead and walked towards the building.

Chu Yuntian and the three of them also walked in, and when they went up to the third floor, the fat man opened the door and walked in. Chu Yuntian and the three of them also followed, and as soon as they entered the room, the fat man took out a document bag from his clothes and said, "This is the latest information of the researcher, let's take a closer look at it if you have time." ”

Chu Yuntian took the document bag and nodded, "Thank you, brother." After speaking, the document was handed to Xiaoya and said, "You two go back first, I'll talk to the fat man for a while." ”

The second daughter nodded obediently, and walked out of the room with the papers.

Watching the second daughter walk out, Chu Yuntian turned his head to the fat man and said, "Have you studied paleontology now?" ”

The fat man nodded and said, "Yes, we have been studying the phenomenon of biological atavism, and whether ancient biology will also advance, how do you know?" ”

Chu Yuntian said thoughtfully, "What is the origin of your dean?" ”

The fat man sat on the sofa and said: "Our dean used to be a paleontologist, and he was also the first batch of natural evolutionists, and now he is a fourth-order evolutionary. ”

Chu Yuntian walked over and said in surprise, "What? Are your deans all fourth-order? ”

The fat man nodded and said, "That's right, the heads of the major forces in the capital are all fourth-order. ”

Chu Yuntian calmed down and said, "So powerful, what are the most powerful steps in the capital?" ”

"The highest should be the colonel of the army, Situ Kong, who is already the fifth order," the fat man thought for a while and said.

Chu Yuntian was shocked again: "Fifth Order, how did he advance so quickly?" Isn't it true that you can't use energy beads to advance after the fourth order? ”

"It's all in the information I gave you." The fat man whispered.

Chu Yuntian nodded and said, "Well, when I go back and see, have you caught any living ancient creatures?" ”

The fat man shook his head and said, "No, but I have found some signs of paleontological activity, presumably there should not be many of those paleontists, otherwise it is impossible to find none of them." ”

Chu Yuntian walked next to the fat man and said, "Fat man, do you have any plans for the future?" ”

The fat man sighed and said: "What can I plan, in the current situation, if humans can't quickly find ways to become stronger and use more bioenergy, they won't last long at all, those individuals are strong, but the most worrying thing is the wolf pack, and the situation like the stone mongoose, the race reproduces quickly and has strong cooperation ability." ”

Chu Yuntian said puzzledly: "Aren't all human thermal weapons usable?" ”

The fat man sneered and said, "Humans don't have so much energy, do you know how much energy it takes to build this city?" In fact, the power was cut off a month ago, and if it weren't for the discovery of a way to convert bioenergy into electricity, food would have been a problem. ”

"What about nuclear weapons and missiles?" Chu Yuntian asked again.

The fat man said helplessly: "You can use it at the beginning, but where to fight?" The whole world has become like this. Now there is no energy to power those weapons, and it has all turned into a pile of scrap metal, and now humans have to evolve faster than these creatures if they want to survive. ”

"Then you haven't studied why the earth is like this?" Chu Yuntian asked all the thoughts in his heart.

"I have studied that our original world is composed of a variety of substances, but there is no such thing as biological energy, but since that fog, this kind of energy has appeared on the earth, but this energy does not only exist now, it also existed in the paleontological period, otherwise the animals and plants at that time would not be so powerful, but why did this energy appear, we now have no ability to explore the entire earth, so there is no way to know." The fat man said helplessly.

"So there is no other way for humans to evolve than to evolve faster than all living creatures?" Chu Yuntian said with a frown.

The fat man nodded, but without answering, the two fell silent......
