Of course, there were those who didn't want to be tied down by a fixed job and preferred to freelance.
One could go up to the city wall to kill zombies, with room and board included, and receive a monthly salary of 1 million, along with a shopping card for the ATM,
valued also at 1 million.
Each person, 10 Energy Water Drops a day.
Hua Mi intended to have them, as long as they didn't collapse, continue killing, killing, killing!
The condition in return was that all the Zombie Crystal Cores they killed would belong to Hua Mi.
The survivors who came to kill zombies didn't see this as a problem at all, because with so many zombies below the city wall, they themselves couldn't possibly go down and get the Crystal Cores.
If they had the capability to go down the wall and retrieve Crystal Cores, they wouldn't be just hanging around on the walls of Xiang City Base.
