I Was Already Invincible, Only Then Did Terror Come.

What, a zombie wave breaks out? Don't panic. I'll gather my strength first and it'll be just a matter of time. Aren't they just a few fierce ghosts? I slapped Chu Renmei to death, so don't make a fuss. Met a pervert? Then you have found the right person, I am their ancestor! From the National Security Agency? I'm forced to be an instructor. Sorry, I'm not interested. But if you want to give me money, then I won't be sleepy! This novel and its characters are purely fictitious.
