I'm Really the Dungeon Master

A young man from Earth was reborn as Ryan Lawrence, and gloriously became a dungeon master. I thought I could enjoy the luxurious life of a city lord. But what the hell is the message "Players enter the dungeon three days after entering" displayed on the dungeon announcement panel? And what the hell is "players attacking the city in three months"? In order not to be killed by these players. In order to survive, the perseverant, brave and wise Ryan Lawrence decisively chose cheating! "I want all players to know that the dungeon world is full of death and danger." Ryan Lawrence said. This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
