A zombie virus broke out in Ai Ye's world. He managed to survive for ten years, but one time he encountered high-level zombies while looking for food. The second before he was about to die after being attacked by the zombies, a thing claiming to be a system said that it could go back in time and that it only needed to complete some tasks for it.
According to the system, as long as we go back in time to the node before the zombie outbreak, it can solve the problem of the meteorite that crashed into the earth and caused the zombie virus to spread.
Aiye agreed.
She was sent to various worlds to obtain points. Without changing the world line, she could complete the request of the small world and obtain points that could go back in time.
Intention: Just being alive is the greatest happiness
