The Guide to the End of the World: Four Sentinels Compete for Favor

Ai Wanxin and Yi Shenshou entered the elevator. She glanced at the light blue display screen again to confirm that the weight part on the screen was really gone. She asked curiously, "Why is this scale not working?"

Yi Shenshou digested the name of the scale for a while before saying, "The rats chewed the power cord of the mainframe of the security center, and now we can't buy a new one for the time being, so the pressure sensor and monitoring system are paralyzed."

Is it such a coincidence?

Ai Wanxin sighed: "What kind of mouse is so powerful? Could it be a mutant mouse?"

She now had a headache when she thought of animals that could dig holes underground, but how come this mouse was so smart that it only bit two systems that were quite inconvenient for her?

This is a good trick. Next time when there is a place that is inconvenient to enter, I will ask someone to chew the power cord first.

"It's not impossible. A mutant mouse in the laboratory just happened to escape. It might have been the one that gnawed it."

Ai Wanxin's eyes twitched slightly: "The mutant rats in the laboratory escaped?"

Could it be that they have bred another large nest underground?

Yi Shenshou didn't seem to be bothered at all by the security system's breakdown and the lab rats' escape. He said with a smile on his face, "Don't worry. They are specially bred cloned lab rats. They are infertile and won't become a large litter."

Ai Wanxin was amused by him: "How do you know what I'm thinking?"

Yi Shenshou's eyes curved slightly. He didn't know why, but he inexplicably felt that her face was a little easier to understand when she wrinkled.

He handed Ai Wanxin a card: "This is a temporary access card. It grants access to all floors of the Institute of Biology, including the underground laboratory. With it, it will be convenient for you to enter and exit in the future."

Ai Wanxin took the access card with a smile and praised: "You are so thoughtful. Xiao Yuandan is right. You are so nice."

Yi Shenshou cleared his throat somewhat embarrassedly. Fortunately, the elevator quickly went down to the tenth floor underground. After getting out of the elevator, Ai Wanxin found that the layout here was exactly the same as that of the laboratory upstairs, with a door access on each side, leading to a circular corridor in opposite directions.

The door on the right side of the elevator was wide open, and soft incandescent lights illuminated the entire corridor. After a while, several people in white coats were walking back and forth between different rooms on both sides of the corridor.

Yi Shenshou said softly, "That's the scientific research team brought by Professor Tan."

Ai Wanxin asked: "Why did they come to your laboratory?"

Yi Shenshou drooped his eyelashes slightly. "Because Professor Tan's research needs the help of me and the teacher, she... seems to be under great pressure, so she is a little anxious. She thinks that deeply participating in my and the teacher's experiments may have a positive effect on the progress."

Ai Wan's eyes turned slightly, and she asked knowingly, "What is she researching?"

Yi Shenshou chuckled and said softly, "It's not important. I'll tell you slowly later."

He looked at the other side of the corridor with a closed door: "Over there are the animal room and the plant room, do you want to take a look?"

"Okay!" Ai Wanxin followed his words and said, "Besides mice, what other animals do you raise?"

"In addition to the jailbroken mice, there are also rats, rabbits and monkeys." Yi Shenshou used his fingerprint to swipe the door open and walked in with Ai Wanxin.

The access control system clicked and automatically locked behind the two of them. The temperature here was obviously lower than outside. Yi Shenshou took out a cleanly washed white coat from the cabinet nearby.

"There are no new white coats in stock here. If you don't mind, you can wear mine."

He shook out his white coat, put it on Ai Wanxin, and put on another one himself.

The sentry had a very sensitive sense of smell. Ai Wanxin could clearly smell a light fragrance on the white coat, exactly the same as the one on Yi Shenshou.

The two left their shoes at the door, washed their hands first, then entered the air shower room, and after a complete set of disinfection procedures, they finally entered the animal and plant room.

On both sides of the corridor are small rooms with locked doors. On the doors, light screens display the status and various parameters of the experimental subjects in real time.

They passed by a room with a vine as thick as an arm. On the light screen, the vine was arching as if trying to break free from some restraints.

Ai Wanxin asked: "What are you doing?"

Yi Shenshou paused and said, "It is shedding its skin."

"Huh?" Ai Wanxin looked at the vine in confusion as it broke free from a dark brown shell. The vine, which was originally as thick as an arm, stretched its muscles and became as thick as a calf.

"Won't it be dangerous if you cultivate this...?" Ai Wanxin asked uncertainly.

"Once they evolve to the point of being out of control, the defense system will automatically inject liquid nitrogen into the room, and everything will stop." Yi Shenshou's gentle and indifferent voice sounded, his eyes calm and deep, and no one knew what he was thinking at this moment.

As they continued walking deeper into the corridor, Yi Shenshou slowly asked, "Do you believe that humans can control the direction and speed of evolution of other species, or even humans themselves, and turn natural selection into autonomous choice?"

Ai Wan thought about it and said, "Theoretically, it's possible."

"Do you think this is the right thing to do?"

Ai Wanxin blinked his eyes. He was asking himself, is the secondary evolution project reasonable?

"Hmm..." Ai Wanxin thought for two seconds and then said, "I think some issues don't need to be argued so clearly. When people make a decision, they can never predict what the result of the decision will be, whether it is in line with their expectations or against their wishes. So generally speaking, you can choose what you want and then pray for good luck."

Seeing Yi Shenshou paused, she made a patch and said, "I'm lucky. You can choose with me."

Yi Shenshou couldn't help but laugh. He nodded gently: "Okay, I'll choose with you."

The two walked through the plant room area and entered the animal room area behind another gate. In the room closest to the door, a UV disinfection lamp was on. Yi Shenshou explained, "The escaped mouse originally lived here. It melted through three layers of tempered glass, melted through the metal steel plate, and made a small hole to escape."

"What modifications have you made to it?" Ai Wanxin asked.

Yi Shenshou was silent for a moment, then said, "I'll take you to see it later."

Walking further, Ai Wanxin found that the temperature of the air conditioner was even lower. It would be more accurate to say that it was like walking in a cold storage rather than air conditioning.

Yi Shenshou tilted his head and asked, "Are you cold?"

Ai Wanxin was certainly not cold, she was just wondering why the temperature here was so low.

But she soon found out why.

"Boom-"

"Boom-"

A strange muffled sound came from the front. Ai Wanxin walked quickly to the front and took a look. In the room on the left which was separated by a whole wall of glass, a rabbit with red flames all over its body was frantically hitting the glass curtain wall.

Yi Shenshou's eyes flashed with pity: "Just slightly increasing the concentration by 0.01%, the experimental group was unable to control this power."

Ai Wanxin's ears twitched slightly, and she felt that she was infinitely close to the truth. She asked tentatively: "What concentration?"

Yi Shenshou walked to the end of the corridor and put his palm and eyes on the access control device. With a "click", the access control device, which was as heavy as a bank vault door, slowly opened inward. He turned around and spoke in a gentle voice, but the words exploded in Ai Wanxin's ears like thunder out of the blue.

"Concentration of extracts in a meteorite encased in organic matter."
