In the year 2399, all of humanity is drawn into a game known as Doomsday Hotel. Every player who enters is given a basic hotel. The higher the level, the larger and more powerful the hotel becomes. In his previous life, Ryan Charles sold his hotel for $30 million. Little did he know that 30 days later, the Earth would descend into a doomsday, and the hotels within the game would manifest in reality as shelters. As a result, Ryan fell into slavery and met a miserable end. Who could have imagined that when he opened his eyes again, he had returned to the very day he was pulled into the game—and this time, he was bound to the strongest system. Trash men and scheming women come to provoke him? They only end up getting slapped in the face. While other players are still trying to figure out the game's mechanics, Ryan has already built a top-tier luxury hotel, gathered four beautiful maidservants, and is comfortably lying back, waiting for Doomsday to arrive.
