With the passage of time, this small team of survivors with only twelve or three people left finally entered the exit corridor of the base from the safety staircase. This tunnel is about seven meters wide and more than thirty meters long. The ground is an automatic conveying rail, but now the conveying rail can no longer move.
The iron gate at the exit of the tunnel is more than ten centimeters thick, which is unusually heavy. Although there is a pulley underneath, it is not easy to push it away.
After the team came out of the safety staircase, the zombies had already noticed the hall on the bottom floor of the base at the other end of the corridor, and began to stumblingly and slowly approached. The area of the ground floor hall is very large, and there are almost hundreds of zombies.
