When a few people entered the room, there was a breeze on their faces, and looking at the ventilation door that had been opened, a few people knew it. There were so many zombies at the door before, and I knew that someone had already thought of leaving here. And from a certain point of view, those who can survive until now are more or less powerful people, and the more such survivors go out, the more hope there is.

Among the group, only Lin Ben stared at the vent with a strange expression.

Several people quickly climbed into the main ventilation tunnel and climbed down the straight ladder.

When the grenade exploded, Mo Xiaoxian and Zhang Zimo had already climbed very low, and Mo Xiaoxian felt that he had climbed at least 100 meters, that is, according to four meters per floor, a total of 50% of himself should have climbed more than half. Keeping the same posture and crawling down, Mo Xiaoxian felt that his body was a little stiff, and he felt a fluctuation from above, and heard the sound of explosion. Mo Xiaoxian frowned, looked at Zhang Zimo, and saw that Zhang Zimo was also looking at him, obviously noticing the movement above.

The two of them both sped up their downward climb because they were both abilities now, and they could use their abilities against zombies, but they didn't work well with the others, so they didn't want to run into other survivors.

Although the further down the road you are, the more likely you are to run into survivors, it is clear that the people you meet are from this experimental base, and they don't want anyone to know about their existence, or if both of them have gained abilities.

The security guards Lin Ting and Zhao Qi were the first to climb down, Lin Ben was the first to go down, and the man from Nasven went down, but Wang Wen, who was a woman, followed last, still expressionless, as if she didn't care about all the changes and was not afraid.

Soon after the five people went down, a light red monster walked through, and the horizontal pupils flashed, and the zombies who were blocking the door seemed to sense some danger, and automatically retreated, making room for the monster. The monster came to the door and sniffed lightly, sensing the breath of the prey and immediately crashed towards the alloy gate, but the monster was bounced back, and the special gate was thick enough for the monster to break.

The monster who didn't break the door shrank his horizontal pupils, and paced at the door with a sound of crawling, even though there was movement here, but the zombie door was aware of the monster's coercion, and swayed away.

The monster seemed unwilling, but it suddenly left, and jumped down the stairway without stopping, trying to go to the lowest level and catch its prey

Zhang Zimo and Mo Xiaoxian had already climbed to the near low level, but when they were about to reach the low level, Zhang Zimo stopped and motioned for Mo Xiaoxian to stop as well. Zhang Zimo took out a screwdriver from his bag, poured it on the passage wall next to the straight ladder, and pry off a board after a while, Mo Xiaoxian only noticed that there were some small screws with the same color as the passage wall on the passage wall, they fixed these metal plates, and there was a small hole in the metal plate if you looked carefully, but the hole was too small to be seen if you didn't look carefully.

Zhang Zimo opened a branch of a ventilation pipe on the ground floor, which could avoid a lot of trouble. The two of them weren't worried about something in the ventilation duct, and if there were, they should have seen it a long time ago.

When the two of them entered the ventilation duct on the ground floor, they put the removed metal plate back, although there was no screw fixation, because of the shape of the metal plate at that time, the metal plate would not fall under normal circumstances. This will also avoid the wave of people behind.

The two shuttled quickly through the pipeline, and with Zhang Zimo's familiar structure, the two moved smoothly, getting closer and closer to the exit. Zhang Zimo did not hide that he had obtained the structural diagram of this underground laboratory before he came, but they also sacrificed a lot of people.
