By the warm bonfire, light emerged from the dead branches of reeds and scales, and the stones in the fire cave were burning and crackling.

With the continuous shaking light source, Wu Jin took out the small characters on the exchanger under the attention of his three teammates.

Evolution point: 1 point.

"The Red Queen hypothesis - under the established ecological environment, all species are competitors in the evolutionary game."

"Before entering the arena, my guess was that the 'contenders' were Panlong, the Terror Head Beast, and dinosaurs that had not yet appeared on the field: species evolved in the environment, chose the direction of evolution, created evolutionary advantages, and surpassed the opponent and squeezed out the niche to win."

"Compress this model at the limit," Wu Jin turned the cube in his hand, with a slight calluse, and his slender fingers gently rubbed each side in turn: "The Red Queen hypothesis is the rule of the game, and each population is a single player. Functional mutations under low probability are evolution points. The way for population development is to use evolution points to light up the talent tree."

Ming Yao and Sora reacted first and looked at the exchanger at the same time.

Ming Yao: "Based on the meaning of the materials... are you saying that the competitors under the Red Queen Game - also include the players?"

Wu Jin nodded and pressed the virtual projection on the exchanger.

The light hit the middle of the team sitting around, and the flames of the bonfire gathered together. Wu Jin stood up, half of his body was shrouded in bright light, and half of it was immersed in the cold and humid night of the Permian:

"The supply method of the fourth knockout match is different from before, because the rules of the Red Queen need to include players in it. The only difference between players and natural species is that the evolution points of natural species are given by time, and the evolution points of players come from the program team's materials."

"And the conditions for winning are completely consistent - if you want to win, you must choose the right direction of evolution."

"There is only one evolutionary tree. Each branch grabs the evolution point and chooses to add points to different branches - corresponding to species that evolve into different advantages to cope with environmental selection and species confrontation."

Several people looked at the projection screen in unison.

“Several redemption categories.”

"Respiratory equipment is used to exchange for high-adaptive and high-pressure-resistant respiratory systems, similar to the evolutionary direction of birds in the Jurassic period of the Mesozoic. The dual respiratory system in the birds can ensure that two gas exchanges occur during the same breath, thereby drawing a large amount of oxygen in the flight direction."

Wu Jin continued to analyze: "Armor category, corresponding to biological armor."

Lin Ke's mind flashed and raised his hand without thinking: "Stebra Dragon! I know this!"

Wu Jin nodded: "The evolution direction of armor and stegosaurus is similar. Stegosaurus resists predators' attacks through the spine-like plates, tail spikes, and highly keratinized epidermis."

"Weapons, predator direction."

"Speed, organs, illustrations..."

Wu Jin's voice is light, but stable and clear.

The fire gradually weakened, and Mingyao volunteered to continue to add firewood. The rotation of the upper and lower middle of the night had passed, and the other two teammates fell asleep, leaving Wu Jin and Mingyao on duty.

"In the long run, competitors' victory has predictable evolutionary potential. So, if we add points to the evolutionary tree, we must focus on the long-term direction. For example, dealing with the mass extinction?" Ming Yao rubbed his hands beside the fire and asked in a low voice.

Wu Jin agrees.

While they were fine, the two began to explore the extinction mode that ended the Permian.

Every contestant was allowed to bring some irrelevant small items when entering the venue, such as the eyeliner of Thunder Chuanhuo. Wu Jin chose the most basic paper and pen. Two hours later, the draft paper was full of speculations.

In the middle is a simple evolutionary tree, and species before and after the Permian are classified in sequence—

Ming Yao threw away his pen with a bang and breathed a sigh of relief.

Wu Jin rubbed his arms, but it looked much easier than before.

A vein in the evolutionary tree was tracing several times by the pen tip.

The guess is finally finalized.

"A gamble?" Wu Jin spoke.

Ming Yao nodded fiercely.

Unlike Wu Jin who had been squinting for a while, Ming Yao really didn't sleep all night, but he looked very excited. He lay on the ground in a large font, putting the draft on his head, and his eyes were full of emotion and respectful: "400 million years, how small is this probability to evolve at the peak of genes to us..."

Wu Jin nodded, showing a respectful expression: "Primary, human family, Homo genus Homo sapiens. It's really not easy-"

Ming Yao continued to finish his words: "...it can only be possible to evolve our captain at the peak of his genes!"

Wu Jin choked: "..."

Ming Yao took the draft paper off his face, his face full of excitement, and he would pull Wu Jin to join the pyramid scheme in minutes: "Our captain is amazing, no one can defeat the sniper and rifle of two thousand meters! His five senses are still keen. When I sleep, I gently turn over the captain--"

Wu Jin suddenly realized: "You Jing Yi is really like the rumor. In order to cultivate a tacit understanding, you have to sleep together with the two C..."

Ming Yao immediately retorted: "How is that possible! I was talking about my childhood, when I was a child! When I first joined the team, I was young, and the captain took me to sleep like a baby. Hey, don't say that many babies want to sleep with our captain. I moved a small pillow at night and rushed over. The captain's door was not locked yet, so I secretly bought a lock online and locked it when I went in! No one except me would think about coming in!"

Wu Jin was dumbfounded, and his pupils widened and looked at the in-service contestant and retired baby in front of him.

Ming Yao said, touching his head again, feeling a little embarrassed: "I really want to review it with the captain after saying this... Hey, you said there is any way to climb the bed again? Hey, don't get me wrong about our captain being a straight man! The kind who has a girlfriend! Hey, I want to go back to marry her after winning the championship!"

The "straight man" was underestimated by Ming Yao, but Wu Jin's soft curly hair suddenly became nervous and raised as if he was a sheet of paper. He saw that there was no movement and quietly recovered.

However, Ming Yao refused to let go of this word: "I learned from the captain, so I am also a straight man! But I am quite happy to make a CP," while the camera position was adjusted at night, Ming Yao had already let himself go, and looked at Wu Jin with pity: "Of course, you can't understand it. Our Jingyi CP is essentially different from the soulless scarf CP-"

Wu Jin finally couldn't help but speak: "I have a soul! I, I'm actually a little happy to fry..."

Ming Yao was happy and raised a finger and shook it: "I admire the captain very much. Do you have any respect for the guard player?"

Wu Jin didn't even think about it: "Yes!"

Ming Yao: "The captain is very caring for me. Does the guard player treat you?"

Wu Jin replied in seconds: "Yes!"

Ming Yao didn't expect that Wu Jin was still an invisible lever, so he used his last move: "If I suddenly became a girl - of course, if I were a woman, I would definitely not be the face I am now. I think I might have a crush on our captain! A crush on you! Do you know how to do it? "

Wu Jin: "…will."

It will now.

Ming Yao obviously disbelief and shrugged at Wu Jin, a gang spirit, saying that he could not fight and turned around and went to add firewood.

Of course, Wu Jin could not perform a secret love for him on the spot, so he stuffed the draft into his backpack and continued to watch.

The night breeze in the Permian period was slightly cool, but it was not a stinging muscle under the warm surface temperature. The fern wood forest has not yet evolved from the woody fragrance of millions of years later, with fishy and sweet moisture. The bright night sky of the galaxy and two crescent moons separated by a distance.

Wu Jin turned his back to Mingyao, wrapped in a parachute cloth, and his mind was Wei Shi's battle with the terrifying beast.

It's like a person secretly replaying a cartoon. After the playback, he looked up happily. He raised his mouth among the thousands of stars, flattened, and raised it again. His pupils were clear, and he printed out the vast sea of ​​meteors passing by.

There was just a missing guitar.

Wu Jin has already begun to lose control of the composition of the music!

Let me accompany my elder brother to watch the meteor shower fall on this planet~ Let the little pterodactyl fly around us...

Wu Jin beat him up.

He suddenly stood up and called Ming Yao, his expression suddenly changed: "Meteor, it's a meteor shower!"

It was getting darker and the four-person team was ready again, and the atmosphere was much calmer than last night.

Wu Jin briefly mentioned the strangeness of meteors and his own and Ming Yao's speculation. Lin Ke agreed unconditionally, and Sora nodded after briefly thinking.

Before leaving, Ming Yao took the time to fill in half an hour, and Sora helped Wu Jin to check it out: "There are two branches in the respiratory equipment. Class A provides 30 minutes of high-concentration oxygen supply without burden, suitable for high-explosion combat and team first aid. Class B provides 24-hour normal oxygen supply, and can be extracted and operated at a minimum of 12% oxygen. The above are all exchanged at a rate of 1:1 for evolution points."

"In addition, the basic oxygen supply equipment 1 evolution point can be exchanged for 2 units - the operation requirement is that the surrounding oxygen concentration must exceed 21%.

"If you exchange 4 Class B and 4 basic oxygen supply equipment, there is still the last 1 evolution point left." Sora's review was completed: "You can leave emergency response, or exchange 1 Class A equipment to prevent suffocation."

At this moment, Lin Ke caught two more lizards and looked at Wu Jin and Sora: "What does it mean? What Class A and B? What respiratory equipment?"

Ming Yao, who had just woken up from sleep, stretched his waist and went over to take off Lin Ke's shirt: "Hey, did I poke your waist yesterday? It's not green, I'm quite strong."

Lin Ke quickly covered his waist: "Big brother, don't, don't! The camera is watching--"

In the faint morning light, the rearranged camera position was turned around the four people.

Wu Jin yawned, raised his head in a sleepy way, and suddenly stared at the camera that flew straight to the front of him with big eyes.

The amber pupils were faintly damp, and the eyes were confused.

Wu Jin suddenly reacted, smiled and showed his white teeth, turned the camera away, and helped it fly towards his teammates.

One night passed.

The giant fern forest changed again, and the reed trees were even more lush than last night's heavy rain, and they could not even see the top at first sight. As for the vertebrates, the group of dragons originally wandering in front of the cave, have disappeared without a trace.

Wu Jin and his teammates exchanged their eyes silently.

Panlong is extinct.

The timeline moves forward again.

Several people trek back to the valley. The musk-footed beast, which became a prey of a terror beast last night, still fell by the water. A small, primitive crocodile was picking meat on the corpse.

"Crocodile-shaped, the main dragon, and the consuming rot." Wu Jin explained: "One of the species that survived smoothly to the Triassic."

Lin Ke thought: "Master Dragon? Why does it sound familiar?"

Wu Jin smiled and said, "The main dragons have divided into four most well-known species from the Triassic to the Jurassic, dinosaurs, pterosaurs, and crocodiles with strong vitality and birds."

Lin Ke grew up and was shocked for a long time. He didn't mention the male god dinosaur again for the first time: "Bird...bird! Can we catch an Archaeoptera bird and roast it? You can't always eat lizards!" The other teammates quickly raised their hands to echo.

After a while, Lin Ke asked again: "Brother Wu, Brother Ming, what other animals are there that have lived to the Triassic period?"

Ming Yao and Wu Jin discussed it all night and spoke lazyly: "The water dragon beast, the sea creature with the least calcified tissue, small herbivores, lizards, and snakes. They all have one common characteristic..."

The four of them searched the valley but did not find a second supply box. At noon, the sky shook again, as if something was roaring and flying past the atmosphere. Everyone who was about to track the musk-footed beast tribe again was shocked.
To be continued...
