Duan hope was a killer in his last life, and he will be in this life too. As a hard-working killer with no quirks or psychopathy, he only cares about making money. He just has a weak sense of presence, and he is also a paralyzed person who is easily stubborn. [The sense of existence can be compared to the seventh person in a certain fantasy] It cannot be found in three lifetimes. The little killer has been asking himself a question. Why do you exist? Why does it exist? The author doesn't know this question. However, in the new world, there will always be someone to tell him the answer. I hope so. To put it simply, this is a story about a killer brother with a weak sense of existence who travels through the martial arts.
