Doomsday: I Opened the World's Genetic Lock

[Hoarding + multiple female protagonists + decisive killing (a normal person with feelings) + brain storage] This is a doomsday city where zombies are rampant and mutant beasts are infested. It is also a dead city abandoned by the world. One year! Lin Hao has experienced a hellish life for a whole year, and finally one day! He sacrificed almost everything to escape from this doomsday city with his sister. As a result, he discovered that he had been abandoned by the world. Directly in front of him, countless tanks, helicopters, and soldiers were pointing their guns at him. "Stop, go back!" "You must not leave the city of doomsday!" Someone said. Later, the sister in her arms was shot in the head. Lin Hao, who lost his mind, also followed closely. At the same time, a strange voice sounded in my ears: "Whether to turn on the genetic sequence!" "Yes!" ……….. When he wakes up, Lin Haozhong will meet before the doomsday breaks out. Is it rebirth or meeting the future? Since he was reincarnated, he had to make this last world a little different. "Mr. Lin, the two thousand tons of pork and two thousand tons of beef you ordered have been delivered." "Ms. Lin, here are the 100 servings of ice cream you asked for." [Ding! Congratulations to the host for successfully synthesizing "super-large mutant maggots that are good for nothing but disgusting!"
