Lin Yuan, a game planner in his previous life, traveled through time and became the core of a dungeon - Leyline Node No. 7743.
Others traveled through time and became a brave man, a demon king, or Long Aotian, but he traveled through time and became an immovable crystal.
It doesn't matter, just farm if you can't move. Setting up non-fatal traps, cooperating with the Adventurer's Guild, engaging in underground trade, developing the population... He just wants to run his own small dungeon quietly.
But trouble always comes: church trials, abyss invasion, secrets of civilization, world crisis... Forced into a corner, Lin Yuan had no choice but to take action again and again. As a result, every time he took action, the whole continent became more convinced that the core of this dungeon was the most terrifying demon king in history!
"I really don't want to be the devil!"
