At the Beginning of "Hundred Ghosts Walking at Night", I Spent My Life to Strengthen the Door Panel.

Wu Yuan woke up from a ruined temple and encountered hundreds of ghosts walking in the night on the spot. When he was in danger, he discovered that he could strengthen the temple gate and block the invasion of ghosts by spending his lifespan... After walking out of the ruined temple, he discovered that he had traveled to a terrible apocalypse. The place is sparsely populated, dead quiet and cold. Towns are isolated from each other, like the end of the world. The brilliance of technology has been extinguished, leaving only embers. What's even more frightening is that ghosts, demons, evil spirits, and unspeakable foreign objects... Wander in the wilderness forests and abandoned cities all day long. Wu Yuan can only rely on the "Krypton Life" plug-in to survive in this crisis-ridden world.
