Three years ago, Chen Jin, an S-class superpower, was deactivated by the organization's "Shen Ce" and faked his death to escape during the pursuit. Three years later, he made a comeback by devouring the system and sneaked into the underground world with a new identity. He must swallow the enemy's superpower fragments, strengthen himself in the backlash, and at the same time trace the clues of the betrayer. He formed an alliance with the intelligence dealer Bai Ye and was taken in by the mercenary leader Tieshan. Facing the ruthless enforcer Su Yanluo, he made every move, but found that all the clues pointed to the vice president Wei Wujiu. When the truth was revealed, Liu Ruyan, whom he trusted most, was also involved. The abolished superpower is the game, the devouring system is the key, and revenge is just the beginning.
