Wang Tao came to the door of room 202 and knocked.
"Who is it?"
A low male voice came from inside after a moment.
"I'm from 501 upstairs. I've cleared the zombies in the building, so it's temporarily safe. If you lack food, you can search other rooms, but try not to touch the zombie blood. Also, don't open the unit door. Currently, there are only four of us alive in the whole building: you, me, 302, and 502. If you need anything, you can come to 501 to find me..."
Wang Tao briefly explained and then went upstairs without waiting for a response.
Inside room 202 was the balding uncle, the locksmith. In the previous life, he taught Wang Tao the locksmith skills, which provided Wang Tao great convenience in the early days of the apocalypse. Unfortunately, he was eventually killed by that spectacles man. Wang Tao always felt regret. Now, living again, with his ability, Wang Tao naturally wanted to help.
