Please Give Me Eternal Life a Face

Suddenly obtained the inheritance of eternal life and became an immortal, immortal, immortal and immortal. What? You ask me, in this city where people with superpowers are everywhere and there are many monsters, what is the use of immortality, a ability that can only be beaten but cannot fight back? Well, thinking about it carefully, it seems to be of no use... Ha? No, I will complain. Bah, no, as an immortal, I have... Favors. The person next door owed a favor seven hundred years ago and has not repaid it. Old Liu Gang of the Special Investigation Department accepted a lot of favors when he took office. It seems that the little fox who lives with me also wants to repay her life-saving grace... In short, although I can't fight, those who can fight will give me face. Moreover, I don't mind selling more favors, because one day... You will always pay them back to me. Do you need help?
