After all, they are all people who have studied in college, and more than 20 people quickly recognize the form, even if they don't understand it, they will figure it out when they look at the big pit on the cement floor of the laboratory.

Regardless of whether it is sincere or for another purpose, everyone chooses to give in for the time being.

Seeing that the result was similar to what he expected, he nodded and Yu Bai said:

"Since everyone has a choice, then from now on we are divided into two groups, each time we go out in two groups of 10 people Wang Lele and Deng Weiguo are the team leader of each group of 10 people, and one more person is assigned to Wang Lele's group, and everyone is gathered together, Chen Chusheng and I only lead one team out each time, and the remaining team is responsible for preparing food. Do you have any opinions? If you don't have an opinion, you can divide yourself into groups. ”

"Now Wang Lele Group brought his novice wooden stick and followed me out, and I didn't ask another group to borrow it. ”

Seeing that no one spoke and consciously divided into groups, Yu Bai was not surprised, looked at the next two groups of people, and glanced at Wang Lele's group, which had the least number of girls, and Yu Bai greeted Chen Chusheng and walked outside the laboratory.

The laboratory is surrounded by a teaching area, Yu Bai took Wang Lele and others, carefully walked through the grass and did not encounter any danger, Yu Bai didn't know how much the zombies had changed in one night?

When he came to Building 53 and heard a slight noise upstairs, Yu Bai stopped, signaled to everyone, and Yu Bai went up the stairs alone. Upstairs is almost no different from before the end of the world except that it is a little darker, and his ears moved, Yu Bai's expression tightened, and he quietly walked to 203 to look inside.

"Identification"

"Level 3 Low-Level Zombies"

"Level 5 Low-Level Zombies"

"Level 4 Low-Level Zombies"

"What's different?"

Three prompts in succession, Yu Bai looked at the zombies in 203, frowned a little suspiciously, and walked in.

Roar roar roar ~~!

The sound of pushing the door woke up the three zombies, and the zombies roared. Yu Bai felt the red line on his forehead hot.

I saw that the zombies with blood-red eyes suddenly became more irritable, a black light appeared in the blood-red eyes, and the tables and chairs in front of him were directly knocked into the air, Yu Bai saw the appearance of the zombie riot and smiled bitterly with a somewhat ugly face, it is really not fun to be cursed.

Fortunately, these zombies are not strong, and the flying tables and chairs that they dodged by mistake, the dragon slaying knife directly eliminated the fifth-level zombies in front of Yu Bai, and Yu Bai's face was happy after a golden light. It's worthy of being an upgraded zombie, I paid attention to this fifth-level low-level zombie, but I didn't expect to contribute 100 experience, and I can upgrade myself by killing 12 fifth-level zombies.

After mutilating the remaining two zombies, Yu Bai didn't pay attention to it anymore. Follow the aisle, once there is a sound in that classroom, walk over and identify the zombies inside!

The fifth-level ones were solved.,The fourth-level and the fourth-level are all disabled.,Although there is no equipment, but the crystal coin is also good.,Yu Bai found that ordinary low-level zombies basically won't burst out of the crystal coins above the intermediate level.,Only elite-level monsters and mutated zombies will burst out.。

However, with the idea that no matter how small the mosquito is, it is also meat, Yu Bai did not miss the fallen crystal coin, although he has not yet found out how to use the crystal coin, but Yu Bai believes that as the only currency that is recognized in the last days, the more the merrier, no one will dislike the money!

After solving the second floor, he called Chen Chusheng and the others up, but Yu Bai himself went up to the third floor, and after waiting for a while, he felt that his experience was slowly increasing, and the corners of Yu Bai's mouth curled.

It seems that these people are not bad. They all dare to kill zombies, the low level is not terrible, I am afraid that these people will not even dare to kill zombies! Yu Bai smiled and began to clean up the third floor, and there was no accident in the same way.

Looking at the experience that has risen to 1780/2000, Yu Bai can't help but get excited in his heart, it seems that he is about to upgrade again. Although he was tired, the thought of becoming stronger made Yu Bai feel that everything was very good.

Looking at those gray and disgusting zombies, I also felt a lot more pleasing to the eye! Thinking about Yu Bai, he prepared to go up to the fourth floor!

"Brother Yu, it's not good!

Looking at Wang Lele, who hurriedly ran up to the third floor, Yu Bai's face changed, and he instantly thought of his title of monarch killer.

didn't bother to answer Wang Lele, Yu Bai ran downstairs. If you don't hold the stairs below, once the zombies rush up, it is estimated that more than half of these people who have just begun to level up will die.

"This ~~ is a guinea pig?"

Looking at the group of big rats blocking the stairs from the first floor to the second floor, the corners of Yu Bai's mouth twitched and he was speechless.

"Brother Yu, we seem to have forgotten about the first floor, these small~uh~ rats should be a total of 50 of them used by the school for experiments"

Chen Chusheng held a Mo knife and explained with a wry smile.

Because he heard the movement on the second floor, Yu Bai went upstairs directly with the dragon slaying knife, ignoring the first floor, but he didn't expect the school to raise the guinea pig to the teaching building.

Yu Bai didn't know what to say. But fortunately, it's not a zombie, otherwise Yu Bai would have scolded his mother!

Because these rats are too big to fit a single mouse up at the staircase, these rats can only roar around the staircase to vent their anger!

"Identification"

"Level 5 ordinary Warcraft ~ Demon Mouse, they are very irritable after demonization. ”

"Ordinary Warcraft?"

Yu Bai's face was strange, since the end of the world, Yu Bai had never encountered ordinary magical beasts, and Yu Bai thought that the lowest level were all elite magical beasts!

Now thinking about it, Yu Bai estimated that the mosquitoes that Chen Chusheng and the others encountered should also be ordinary demonic beasts, otherwise a group of elite demonic beasts would not have the ability to escape so many people from their attacks, even if they were first-level.

Now that I think about it, I understand, looking at the more than 50 mice in front of him, Yu Bai's eyes lit up, killing these mice may not be able to rise to the ninth level, but it won't be too bad!

The corners of his mouth curled, and Yu Bai turned over the dragon slaying knife in his hand and walked down the stairs, Yu Bai's movements completely made the rats riot, and one kept squeezing his body into the stairs.

"Look for death. ”

Yu Bai glanced disdainfully at the rat head that was one size bigger than the table in front of him along the passage, and slashed the dragon slaying knife in his hand without hesitation, and the knife light slashed through, extremely dazzling.

Looking at the rat head broken in half in front of him, Yu Bai kicked the dead rat out with his right foot, turned around and signaled to the scholar to let him get a monster, but he followed the gap where the rat flew out and rushed into the rat group.

With the dead mice, the rat swarm was silent in an instant, and then the rat swarm that had been quiet for a moment like water into an oil pot suddenly rioted violently, and more than a dozen rats directly surrounded Yu Bai in the middle from the four doughs, and the red mouse eyes rushed towards Yu Bai frantically as if they had seen a sea of blood.

Holding the dragon slaying knife, Yu Bai didn't panic when he looked at the rats rushing up around him, these low-level things with no intelligence, in Yu Bai's eyes, were all experience sent to the door, his toes were a little on the ground, and the whole person flew up directly from the rat group.

Looking at the dozen mice that collided together, Yu Bai's body turned, and he slashed out four knives in an instant. Accompanied by four golden rays of light, Yu Bai's body and mind are comfortable!
