In Lujiazui, the financial heart of Shanghai, the demon bone bracelet inherited by intern Cheng Mo can control other people's behavior through mobile payment, at the cost of enduring the target's severe physical pain at the same time - the suffocation of late-stage cervical cancer, the burning of torn nerves in a robotic arm, and the near-death experience of heart disease, all became bargaining chips for him.
When investment bank witch Su Wanqing's Excel human skin is projected on a skyscraper, mechanical doctor Lin Qianxia's ribs turn into antique materials, and hacker Chu Yao's NFT oozes demon blood, the four of them are forced to be involved in a cyber demon robbery that uses pain to measure love and hate. Every time the bracelet "Seven Emotions Lock" is used, the truth about the fire in the orphanage twenty-five years ago is rewritten: it turns out that Cheng Mo is the ultimate container for the resurrection of the Nine-Tails, and the end of all conspiracies is a Möbius strip-like death ending where he and the three women are mutually responsible.
