Huo Chi gripped her waist tightly, as taciturn as ever, but he made her feel warm as spring.

Tang Feng and his friends followed one after another. There were few zombies in the primeval forest, but it was a paradise for mutated animals and plants. They had to find the entrance to the laboratory as soon as possible.

After the end of the world, Professor Yang Zhen and his group were the first group to be secretly sent away by the military. They were on vacation at the time, and Shen Shuyi was not in the laboratory so he did not leave with him.

With Chen Shuyi at their side and following the system's prompts and guidance, they quickly found the experimental building.

However, the entrance to the building was too secretive, so they spent quite a while wandering around outside.

Finally, the entrance information was found by a zombie in a white coat wandering outside. Unfortunately, there were iris and fingerprint locks, so the experimenters who turned into zombies naturally couldn't unlock them.

Shen Shuyi took a step forward, “Let me try.”

She couldn't open the lock, but that was child's play for the super intelligent 66.

The specially made metal door slowly opened, revealing a dark passage inside. The secret laboratory was actually built underground.

"Follow me."

Huo Chi was in front, followed by Shen Shuyi, and then Tang Feng and the others. Xiao Hao had the lowest martial arts value so he was left on the ground to watch the car. They squeezed in the narrow passage and headed for the underground laboratory.

There was a smell of rotting zombies in the passage, which made people dizzy.

Walking out of the dark passage, there is an open hall in front. The hall is in a mess, which shows that this secret laboratory that never sees the light of day has also fallen.

At the corner, a dozen zombies came wandering over, their roars were particularly sharp in the enclosed space. Tang Feng and Wei Hang directly used machine guns to knock the zombies to the ground.

Huo Chi warned from the front, "Be careful, there are many killing devices set up outside this laboratory."
