When Mu Yan woke up, he found that he had lost most of his memory, leaving only a name and an uncontrollable possessiveness. He lives in a reality that combines countless anime worlds, and everyone may awaken powers, summon heroic spirits, or enter a copy. And in his mind, a strange system kept issuing orders, trying to control the trajectory of his life. In an accident, Mu Yan recovered a key memory from a near-death experience - he was once the creator of the entire system, but his memory was tampered with and deprived of authority by someone behind the scenes. That controller is now disguised as an ordinary player, secretly harvesting the power of all awakened ones. With the remaining "god-level possession" golden finger, Mu Yan can seize other people's abilities and use them for his own use. And the crazier he becomes with his obsession, the more unprecedented power he can generate. He embarks on a journey to retrieve all memories and regain system authority, leaving his domineering footprints in countless worlds such as Naruto, Death, Pirates, and Dragon Ball. Possessiveness drives him to become stronger, but the real enemy is hiding in the deepest part of the system, sneering and waiting for him to fall into his trap.
