Xu Mingyuan, a former financial tycoon, was cold-blooded and ruthless throughout his life, and a single thought could determine his life or death. However, after a bizarre car accident, he was reborn with the "Repentance Exchange System". When he opened his eyes, he saw an astonishing negative merit value, and the system forced him to issue an atonement mission: to make up for the families that he had destroyed with his own hands! He used to be aloof, but he was forced to let go of his arrogance, go deep into the bottom, face the victims whose families were destroyed because of him, and experience the suffering of the world. However, the road to atonement is far from easy. When he tried to use money to solve the problem, he was disgusted and rejected by the victim; when he faced the doubts and calculations of his old enemies, his former power had vanished. In a desperate situation, the deeper "Destiny Weaver System" quietly awakens! He has the unique ability to discern cause and effect and intervene in fate. Vague omens, sophisticated causal deductions, and even fine-tuning destiny nodes by consuming "fate fragments"... From the initial clumsy attempt to the combination of the two systems, he skillfully resolved the public opinion crisis, exposed the conspiracy, turned the tide, and brought families on the verge of being broken up one after another back on track. His merits soared and his list of sins gradually cleared. He gradually transformed from a despised "sinner" to a respected "urban hero". However, every intervention in fate is accompanied by the risk of causal backlash. As his abilities improve, he gradually touches the extraordinary world hidden under the city. The ancient causal seal and the sleeping mysterious existence are being inadvertently awakened by his "good deeds". Can Xu Mingyuan truly control his own destiny and become the true guardian of destiny in this torrent of crime and punishment, fate and struggle?
