The high school boy Yin Yongtian suffered from a strong case of OCD. He got on the wrong side of a bully when his OCD caused the bully's proposal to go wrong. He was almost beaten to death, but the trauma activated his Compulsive System! Yin Yongtian wasn't actually all that interested in cultivation, but the System kept tempting him with missions like ”Unanswered Notifications", “Almost Acquired Proficiency," and “Extremely Irregular Hexagonal Panels,” which triggered his compulsion to finish them and become stronger! With skills more than a hundred times more powerful than regular people, he and his friends will venture into the dungeons, and his compulsions will set him on the pathway to becoming the strongest.
