His name is Li Fan, the number one killer on the Tianzihao list, and a top boss worth tens of billions on the global wanted list. In order to find out the cause of his brother's death, he was willing to work as a security guard in an office building. He was yelled at and looked down upon all day long. The boss deducts money, colleagues blame others, and the security captain spits in his face. Until that day, a group of top international killers broke into the building and aimed their guns at everyone. They knelt down and shouted: "Welcome to the palace master!" Li Fan sat on a chair, looked at the people limp on the ground, and lit a cigarette: "I don't want to do this bad job a long time ago."
