Doomsday: It Begins with a USP

The apocalypse breaks out, and Ye Tian is reborn ten days earlier. In his previous life, he struggled through three years amid waves of corpses, only to die in the end when his ammunition and food ran out. This time, he sells his home, stockpiles supplies, rents a warehouse, and seizes resources, building himself a safe base before doomsday arrives. Then, on the day the outbreak truly begins, the Umbrella Biochemical System activates. A USP, a retired veteran, and a complete path to weapons, biochemical research, medicine, and epidemic prevention are now within reach. But a gun can be held in your hand, while food won't grow by itself and ammunition won't fall from the sky. If Ye Tian wants to build up his team and keep their firepower going, he'll have to carve out a way to survive, bit by bit, amid the hordes of corpses and the ruins. This time, Ye Tian has to stay alive before he can think about anything else.
