Everything in the world has "legacies" - unfinished obsessions, forgotten emotions, and dissipated memories. These invisible things will condense into "demon". They feed on human beings' "regrets". They will induce humans to indulge in past regrets and form a resentment around them. What the monster catcher needs to do is not only catch monsters, but also make up for it. Cheng Ange, a young master from a wealthy family, unexpectedly breaks into the world of "Relic Catchers". Together with a group of sincere people, he travels through the world's visions, catching demons and resolving obsessions.
Intention: to overcome all regrets and have happiness in the world
