An ordinary young man, Su Ran, died unexpectedly, but received a "rebirth system" and was forced to go back to the past again and again to correct the mistakes and regrets in his life. Every restart will face more difficult tasks, more complex tests of human nature, and increasingly heavy causal dilemmas. Between friendship, love, family affection and self-salvation, he repeatedly chooses and loses. As the reincarnation cycle continues to deepen, Su Ran gradually realizes that there is a huge conspiracy and the ultimate will of the system behind all this. How can he find the truth in the system jungle, break through the siege of fate, and truly gain a new life?
