Jiang Ji died of betrayal, accidentally obtained the world's "rebirth system", and was constantly reborn with memories in the world of reincarnation. Under the guidance of the system, he gradually became aware of the hubs of the world, organizational struggles, and tests of human nature hidden behind the surface. After experiencing conflicts between family, friendship, love and desire for power, Jiang Ji continues to break through limits and explore his own potential. He met like-minded partners, but also encountered old enemies and despair. Every time he is reborn, Jiang Ji is exploring the truth about himself and the origin of the system. In the end, he understands the meaning of reincarnation and makes a choice - to become the master or to break the system and make the world truly free.
