Lin Yun is an ordinary high school student. In an accident, he accidentally traveled to the Blue Star in the parallel world. He found that in this world, he was also named Lin Yun, but he was an orphan whose parents died young. On the first seven days of his parents' life, a meteorite fell from the sky, followed by a rain of blood. After the blood rain, 80% of the world's humans turned into zombies, but Lin Yun discovered that he was immune to the zombie virus, and that after killing zombies, he would improve his physical fitness and obtain random materials. So when others were hiding from the zombies, Lin Yun kept silent and just kept killing them.
Intention: Doomsday disaster is coming, and human nature is tested in desperate situations. The protagonist, Lin Yun, did not give in to fear and relied on his own strength to fight against the zombies. He stuck to his heart in the cruel apocalypse, kept his kindness and bottom line on the road to becoming stronger through fighting, protected those who deserved to be cherished, and found the hope of survival and the value of life in a collapsing world.
