I, the Urban Legend Creator!

The protagonist Yuan Zhenji crossed into the parallel world of Jiang Shi, and found that this world was full of various horrors and that ordinary humans were as fragile as paper before them. He used a book called the "Urban Legend Records" to create urban legends that affect reality, punish criminals, house horrors, absorb their abilities, and "use magic to defeat magic," becoming a watchdog who fights against horrors. With his allies, he'll counter the impending horror that seeks to extinguish the world.
