In AD 3127, in the interstellar era after a civilizational break, those with awakened blood rule everything at the cost of repaying random "ancestral debts". Shen Yuan, the last descendant of the Shen family, a marginalized person who made a living by live broadcasting challenges, activated the "simulation deduction" system at the moment of death. The system told him: The first step in awakening is to sacrifice all the memories of "mother" in his childhood. He did so and broadcast the deduction live online. The moment the debt was paid off, he gained extraordinary deduction ability, but also forgot why he wanted to awaken. The barrage in the live broadcast room went crazy: [He even forgot why he was working so hard! ] And this is just the beginning. The system prompts that the "fate value" needs to be replenished for the next deduction, and the only way is to execute the "fall option". When the deduction showed that only by sacrificing the luck of his companion Su Wantang could he escape from the family siege, Shen Yuan pressed the deduction button - the entire network watched his choice, his "fall", and the truth he deduced: the identity of the descendant of the Shen family was a lie. His true blood points to the most terrifying taboo in this interstellar era - the ancestral debt that is enough to subvert the family's rule, waiting for him to repay it.
