Lin Yuwei, the real daughter of the Shen family who has been living in exile for twenty years. On the day of return, the fake daughter Shen Xiyu was using the stolen good luck halo to surround the moon. She sneered and activated the "Kately Silk Silk Technique" in her body - each strand of good luck weaved consumes one year of her own life. The first shot made the fake daughter embarrassed in public at a charity dinner; the second shot made the eccentric adoptive mother's stock fall into pieces; the third shot, she hesitated - there were only three life threads left. At this time, a murder occurred at Jinghai University: the original tapestry copy in the intangible cultural heritage exhibition hall was stolen, and the security guard died suddenly and mysteriously. The police were helpless, but the animals quietly told Lin Yuwei: "The murderer smells like the woodcarver's rosewood." During the investigation, she bumped into Xiao Cheng, a wanderer from the world. This man did not abide by the rules of the Arbitration Association, his fists were faster than his spiritual power, and he handed over a contract without saying a word: "Work together to solve the case, support each other, and fall in love by the way? You weave your luck, and I will protect you. If your life is not enough, I will renew it for you." Lin Yu slightly raised his eyebrows: "Renew your life? What do you want to renew?" Xiao Cheng smiled: "Is my life enough?" After the contract was signed, the world was in turmoil. But what Lin Yuwei doesn't know is that every time he uses the Tianyun Kesi technique, his fate will eventually come back in a more twisted way. And that smiling contracted boyfriend, already out of sight of her, blocked the first causal backlash for her.
