After Lin Ce died unexpectedly, he inexplicably returned to the day before the accident and obtained a mysterious rebirth system. From then on, he can only move towards the "real future" by constantly completing system tasks and solving the crises of people around him. However, rebirth is not a panacea. The system's "return to zero" mechanism allows him to return to the starting point of his life once he fails or dies. Every time he returns to zero, he has to face new challenges and unknown evil hands. As he gradually breaks through reincarnation, he uncovers the truth about the world - it turns out that the world he lives in is just an endless experiment of fate. He must unite like-minded partners, battle wits with opponents who also have systems, and find the key to breaking the shackles of cause and effect. In the end, can Lin Ce break away from reincarnation and complete self-salvation and world salvation?
