The strongest esper Lin Chen is betrayed by his cousin Zhao Tianyu, binding with the hotel butler system on the verge of death. Half a year later, he builds the Peach Blossom Spring Hotel in the ruins of the doomsday, domesticating high-order monsters that make the outside world tremble into chefs, security guards, and butlers. With an absolute safe environment and doomsday-scarce food supplies, the hotel becomes a paradise for survivors. Zhao Tianyu discovers that Lin Chen is not dead, uniting the Black Crow Legion and Shadow Pavilion to repeatedly invade. Lin Chen leads the monster employees and allies to fight bloody battles, gradually expanding the alliance, and ultimately clearing out the dark forces to open a new era of coexistence between humans and monsters.
