After reaching the eighty floor, Liu Gan was obviously much more cautious than before.

It's not just because it's dark, but more because the previous detection device has explored a mutated zombie on these floors.

Now Liu Gan already knows that mutant zombies are not only one type, but there may be many types. He has only encountered the tank type with thick skin, thick flesh, and the tentacle monster type with two sharp tentacles. But who knows whether this mutant zombie located on the eighty-odd layer will be a new type?

The new type means that the attack method is unknown, which means unknown danger, so you must be more careful.

However, now there is Galaxy exploring the way forward, and he has fog armor to protect his body, so even if an accident happens, with his current strength and Galaxy, he should be able to deal with it calmly.

In addition to being curious about Liu Gan's experience after entering the game, Zhang Shengli and the other two are also very curious about the mysterious woman "Xiao He" around Liu Gan. This person has hardly spoken much along the way, and always has a cold expression of keeping people away from each other, but seeing that her skills are almost no less than Liu Gan, I don't know how she and Liu Gan got together.

Zhang Shengnan once looked for an opportunity to try to approach the Galaxy, but as soon as she approached, the Galaxy immediately dodged. After realizing something, Zhang Shengnan gave up this attempt.

Eighty-seventh floor, eighty-eighth floor...

Liu Gan became more and more cautious.

"The mutated powerful zombies may appear on the eighty-ninth level. When the mutated zombie appears, don't panic, I will entangle it, try to stay away from the battlefield, so as not to be injured by it by accident." Liu Gan explained a few words to Zhang Shengli and the other two in a low voice.

"Mutual zombie?" Zhang Shengli and the other two asked Liu Gan curiously.

"Well, they are different from ordinary zombies. They may have larger sizes, and their combat power is at least dozens of times that of ordinary zombies. They may also hide in the dark and stretch out tentacle spikes to launch a sudden attack on us, with one blow. With your current strength, you are not enough to fight head-on with this mutant zombie, so what you have to do after encountering is to try to stay away from the battlefield and come and meet me after I get it done." Liu Gan said in detail to Zhang Shengli and the other two.

"It's the boss? After killing, there will be more experience points, right? Will you lose the treasure or something?" Hu Rong asked Liu Gan with interest.

"I have killed three of them and do have a lot of experience. If you want to advance to level 5, you must kill a mutant zombie. But this thing doesn't lose your treasure. If you keep following me, I will have the chance to kill the mutant zombie alone in the future. But it won't work tonight." Liu Gan said to the three of them again.

"We can only look at it from a distance, right?" Zhang Shengnan also looked curious. She had almost never encountered any danger before under the protection of Liu Gan and the two men around her, and she had already let go of her vigilance.

"When the first mutant zombie appeared, I followed a team of ten people. In your downstairs square, we were killed. In the end, I was left alone. The life and death of another player who escaped into the underground waterway was unknown; when the second mutant zombie appeared, two players, one man and one woman, who had followed me, were killed on the spot, and the female player almost died; when the third mutant zombie appeared, a very important companion of my chest was pierced by my side, and he vomited blood and died..." Liu Gan added.

"We should listen to Brother Liu's arrangements and try to stay away from the battlefield as much as possible." After hearing Liu Gan's story, Zhang Shengli quickly told his sisters Zhang Shengnan and Hu Rong.

Hu Rong seemed a little unwilling to accept it, but he didn't say anything. When a male player plays a game and encounters such a boss battle, he knows it's dangerous, but he will be inexplicably excited and eager to try it out. He is really disappointed if he can't participate in it himself or even observe it.

The eighty-ninth floor has arrived. After pushing open the iron door of the fire staircase, there is a deep corridor inside...

A zombie wearing a white coat standing by the corridor and wailing against the wall, heard the sound of the iron door opening, immediately rushed towards the iron door with its teeth and claws.

Galaxy reached out her arm and hugged it with its neck. She added some force and broke its neck and threw it to the ground, but did not kill it. After the others came out, they quickly alerted both sides of the corridor. Zhang Shengli swung the fire axe in his hand and shattered the head of the zombie with an axe.

A ball of black mist that was invisible in the dark floated out of the zombie corpse and all penetrated into Zhang Shengli's body. A very familiar burning sensation appeared in his body, and various indicators such as body strength and speed were further improved.

"I'm promoted." Zhang Shengli looked at his watch and said to everyone in a low voice but joyful manner.

"Congratulations." The others congratulated Zhang Shengli one after another. Before that, Hu Rong had already advanced to level 4 before him. Their three-person team had all accelerated to level 4 after following Liu Gan.

"Shh... I smelled the breath of danger..." Milky Way turned around and stopped everyone's words and quickly disappeared into the darkness.

After level 4, hunting ordinary zombies has lost its meaning to Zhang Shengli and the other two, so Galaxy and Liu Gan no longer hold back when they encounter zombies, which makes everyone's exploration and advance much faster than before.

Finally, Yinhe stood in front of a laboratory door and made a dangerous gesture to Liu Gan. Liu Gan and Zhang Shengli followed him to the wall next to the door and stood. Seeing Liu Gan and Yinhe's serious and cold gazes, Zhang Shengli and the other two became nervous inexplicably.

If only Galaxy and Liu Gan were present, Liu Gan would not feel anything about a mutant zombie. A mutant zombie would not pose any threat to him now. But now he is surrounded by three subordinates he trained, and he doesn't want to lose it casually, so it's better to be cautious in everything.

"Is there anyone outside? Save me..." Just as Milky Way was about to push the door and go in, a young child's voice suddenly came out of the laboratory room.

In the darkness of the night, when everyone heard the sudden sound from the laboratory room, everyone's hair stood up. Liu Gan, even felt a little uneasy.

What kind of strange mutant zombie will this be? It can actually simulate the voice of a human child?

"Please, can you save me?" The young boy started crying inside, the crying seemed particularly loud and cunning in the silent building.
