The world in 2056 is not as bright and beautiful as imagined, but full of violence and chaos everywhere. All because of a large-scale plague that broke out not long ago, this plague has caused great harm to almost all human beings, and countless people have died as a result. People have to spend a lot of money to buy organs to replace them in order to prolong their lives. There is a market when there is demand, and merchants can always sensitively find the location of their business. In such a big environment, a biotech company named Gene co has begun to emerge. The main business of this company is organ buying and selling. People can buy the organs they need in installments. But such a company is naturally supported by powerful underworld forces behind the scenes, and the company has nurtured a large number of professional killers. The mission of these professional killers is similar to that of a dunning person, but the dunning action is accompanied by splashes of blood and death. Because once buyers stop paying for their organs, the company will send these professional killers mercilessly to find these "customers" to take back the organ tissues they bought, and the lives of these "customers" are completely absent. Within consideration.
