In a post-apocalyptic wasteland, neon lights still flicker faintly. Ye Chuan takes over a dilapidated hotel and becomes bound to the Doomsday Hotel System, launching an outrageous business venture: recruiting supernatural beings as employees. A Mist Demon, a Frost Wraith, the Silver Moon Wolf King, and lord-level supernatural beings successively join the staff. Guests are protected by hotel regulations, while troublemakers are immediately expelled or eliminated. With supplies, cultivation, hot springs, and forced recruitment, he expands his hotel while navigating the forces of Haichuan, Yunhao, the Chenxi Base, and various adventurer groups. He must also face supernatural tides and the malice of King-level entities. As the world teeters on the brink of collapse, can the Doomsday Hotel become humanity's last safe haven?
