After Xu Tutu asked, he saw Su Yu on the side in a blink of an eye.

"Why are you here at this time?" He turned to Su Yu again and asked.

Su Yu explained to him with a smile: "I went to the camp of the Hunting Detachment and stopped by to have a look." These are my friends. ”

Xu Tutu nodded, didn't ask anything more, but opened the door behind him a little, turned around and entered the monitoring room.

Seeing that he meant to let the four of them go inside, Su Yu beckoned several other people to walk in together.

Zhao Dacheng, Hao Tian and Zheng Wang came to the monitoring room for the first time, and they were both strange and curious about everything, and they looked around.

There are only two chairs here, and Xu Tutu is sitting in front of a computer monitor writing an observation log.

Su Yu didn't bother him, and simply observed the zombie ugly with the other three people from the monitoring room.

When she looked at it, she found the yellow circle on the ugly ankle.

When Su Yu went to find Wu Xu that time, he bought a special skin care oil for zombies from the black market, and he had already put it on the table in the monitoring room for Xu Tutu when he came to feed Ugly Ugly. After all, she has no experience and can't directly drug Ugly.

Seeing that there is now a yellow amber-like coating on the ugly ankle, it is estimated that Xu Tutu has applied skin oil to it.

"This oil is really exactly the same as the layer on the pile of corpses outside Canterlot." Su Yu said.

Zheng Wang and Hao Tian also leaned over to look.

"That's not." Xu Tutu turned his head, "I haven't started using the bottle you bought." ”

He swiped his hand twice on the computer screen, as if to dig out the observation log from the previous days.

"A week ago, this yellow fluid began to flow from Ugly Ugly's ankle, and then it gradually wrapped the tear." He said, looking at the record in the log.

"You mean, it secretes this protective fluid on its own?" Su Yu was a little surprised, after all, she had heard Chen Yiqian say that this kind of phenomenon only existed in the corpse piles of Central City, and it also happened to the dead zombies.

Xu Tutu nodded: "I always feel that some changes in Chougu are going in a direction that adapts to survival." ”

"It's probably called ...... Evolve? Zhao Dacheng suddenly spoke up and joined the conversation between the two.

"You can say that. It is a favorable change from the appearance of vision to the current outflow of protective fluid from the wound. Xu Tutu nodded.

Su Yu looked at Ugly, she had recently encountered unusual zombies one after another, and she also agreed with Xu Tutu and Zhao Dacheng's statements.

"Have you ever seen that zombie from the other side of the dissection team?" Su Yu suddenly asked Xu Tutu.

"No," Xu Tutu replied inexplicably, "the autopsy team is always secretive, and I don't bother to snoop on them. ”

The five of them stayed in the monitoring room for a while, Xu Tutu planned to go back to the dormitory after writing the observation log, and Su Yu and the others also left the domestication base together.

It was getting late, and the four of them still had to wait for the campus bus in the cold wind.

Xu Tutu always had to transport some ingredients and tools for domesticating zombies, so he had already bought a small tricycle with a half-bucket, and he was always used to driving back when he stayed late at the taming base and missed the bus.

When Xu Tutu drove the tricycle out of the domestication base, he saw four poor people waiting for the campus bus in the cold wind.

Su Yu watched Xu Tutu drive a tricycle past in front of him, and waved his hand to say goodbye to him.

But Xu Tutu drove the car far away, then turned around and drove back.

He parked the car in front of the four of them and hesitated: "If you don't dislike ......"

He gestured to the body.

"Don't dislike it, don't dislike it, brother, you're such a good person." Zheng Wang climbed up first.

Seeing this, the other three also hurriedly thanked them and followed into the car.

The moon is sparse, and the cold wind at night becomes a blow to the bones under the blessing of the speed of the tricycle.

Xu Tutu's eyes were squinted by the wind in front, and the hair of the four people in the car body was also blown high by the wind.

Zheng Wang patted Xu Tutu on the shoulder, and shouted loudly with the sound of the wind: "Brother, your car is simply the most stylish car in our college." ”

After he finished speaking, he turned his head and shouted to the three people in the car, "Wait until we buy one too!" ”

Hao Tian smiled and gave him a thumbs up, and Zhao Dacheng and Su Yu also laughed.

Xu Tutu didn't respond, and the four people in the car couldn't see his expression, but he himself felt the corners of his lips unconsciously hook slightly.

……

Su Yu and Hao Tian returned to the girls' dormitory, washed up and turned off the lights and went to bed.

On the opposite bed, Hao Tian's even breathing gradually sounded, but Su Yu still didn't feel any sleep.

All she thought about was the ugly thing about the amber layer growing on her ankle.

After thinking about it, Su Yu opened the hand screen and found Chen Yiqian's avatar on Call Me. I don't know why such a sassy human head is so simple, it is actually a silver-white bow and arrow.

Su Yu clicked on the dialog box, described the change of the ugly, and sent it over.

Chen Yiqian didn't reply to the message immediately, Su Yu looked at the hand screen, and the message sent in the past had been unread.

Su Yu looked at the time, it was already one o'clock in the morning. Maybe Chen Yiqian was already asleep, she no longer waited for a reply, turned over and tried to sleep.

*

At the same time, outside the center city.

Countless zombies swayed around the pile of corpses in the moonlight, and two heavy armored vehicles quietly stopped in the middle of a group of zombies.

Suddenly, a gunshot broke the silence.

A zombie not far from the armored car staggered, and then limped forward as if nothing had happened.

Immediately after, three more gunshots rang out, and the lame zombie was shot again in the knees and ankles of both legs, and the flesh and bones that had been blasted were not enough to support it to stand, and it fell to the ground on its back with a thud.

The zombies around them did not react to such a sudden situation, and still wandered around aimlessly.

The door of the armored car parked in front opened, and a man in a protective suit and helmet stepped down. He walked over to the fallen zombie and crouched down slightly.

The zombie who was hit in the joints of the lower limbs stared at the sky with a blank gaze, without any pain on his face, and his hands were still swinging unconsciously.

The man in the hazmat suit lowered his head and carefully examined the wound on the zombie's leg, and found that there was nothing extra except the flying flesh and the carrion that was about to fester.

He sighed heavily.

But then, reflecting the bright moonlight, he suddenly saw that a trace of viscous liquid was slowly flowing out of the crack in the bone where the zombie had shot the ankle first.

It was a mucus-like substance that was close to golden yellow, and the man in the hazmat suit immediately pulled out a glass test tube from the box he was carrying. There is an unknown pink substance at the bottom of this tube that is used to prevent the liquid from solidifying quickly.

He held the test tube against the zombie's wound to pick up the liquid.

Because the liquid is very viscous and flows slowly, the process lasted half an hour, and only a third of the test tube was connected.

And the crack in that bone was almost healing.
