When the end comes, countless anime worlds merge with reality, and the world falls into chaos. Luo Hao, a suave ordinary college student, unexpectedly awakened the "Safe House System" - he can build absolutely safe shelters in different anime worlds and summon anime characters as guardians. However, other survivors are also awakening. Some control the zombie army, some have supernatural powers, and the mysterious "Kaoyanwen" organization attempts to control all safe houses and push human civilization into a new era of slavery. Luo Hao is taciturn on the surface, but in fact he is thoughtful. He used the system to build the first safe house in the world of "School Apocalypse", conquered powerful people such as Busujima Saeko, and gradually expanded his power. But each safe house requires "karma points", and the Kaoyan Wen organization is constantly eating away at his resources. Luo Hao must travel around various animation worlds, compete with powerful enemies, and build his own safe house empire in the apocalypse. He is not a savior, he just wants to protect the people he cares about, but he unknowingly becomes the most deadly variable in the apocalyptic world.
