The World's Number One Killer

This is an extremely complex world. On the surface, it is calm, but in fact, there are undercurrents surging behind the scenes. Is this world really as peaceful as you imagine? When a corrupt powerful person falls, a new corrupt powerful person will stand up. There is no end to the evil people. If, under normal circumstances, ordinary professional killers make money by killing people, then will there be a group of killers who selflessly dedicate themselves to justice? Is the world really as simple as you think? Or is this the world we live in? In other words, there used to be a giant criminal organization in this world, with members all over the world, ranging from street beggars to presidents of a country. These people all have one characteristic, that is, they are powerful. They hide around the world in various identities. They can be ordinary workers, technicians, bosses, painters, etc. What kind of world are you creating? Do you know it yourself? Do the people you protect know? Do your friends know? And I live in such a world.
