Doomsday Restart: I Know Three Days in Advance

The global 'Black Rain' event will completely rewrite human civilization. After the black rain falls, all organic matter begins to mutate—animals go berserk, plants grow wildly, and humans split into 'Awakened Ones' and 'Zombies.' The protagonist, Xia Dan, survived two years in the apocalypse in his previous life, only to die from betrayal by his companions. Waking up, he finds himself back three days before the apocalypse begins. This time, everything will be different. — Description from novelcodex.org
