Lin Ansheng is on the verge of death after a car accident when he is reborn in the body of his seven-year-old self on the night of a great flood. Gradually, he discovers that he isn't the chosen one, but a "born vessel." Someone has been using "contracts" and anchors to shift misfortune onto him in exchange for the prosperity of their family. Gu Xuanzhou, the public face of the scheme, poses as a philanthropist while maintaining a century-old industry built on transferring calamity. Lin Ansheng has no cheat ability. His only advantages are that he can "take a beating" and "calculate accurately": he saves people to lessen the backlash, records and verifies patterns, and plants undercover agents in the enemy camp. Su Wanqing has a memory anchor implanted in her, making her an unwitting channel for information. Zhao Lei goes from jealous betrayal to atoning through martyrdom. Lin Ansheng gathers the contract artifacts and uses the Gu bloodline's sincere repentance to sever the contract and return all tribulations to their rightful place. But just as he thinks everything has settled, unfamiliar handwriting appears on the last page of an old diary: "Do you think I'm the only one?" It turns out Gu Xuanzhou was merely an operative, with contract overseers and hidden agents above him. Lin Ansheng investigates the Contract Oversight Hall and devises a formation to sever all contracts, ultimately forcing the hidden agents to retreat by exposing the truth. Ten years later, the lights on the top floor of the building across the street come on again. Standing by the window, he writes: "Whatever you are, come. I'll be here." The story draws to a close amid a warm new beginning and unsettling questions left unanswered.
