무림세가 막내아들로 빙의했습니다

Synopsis

The martial arts book that I discovered in the run down comic store said… "Will you… continue?" When I woke up, I thought I was a noble but… I became dirt poor again. I got the unlucky short end of the stick. The ruined Murim world too, also is a fool for pointing fingers at everyone for being insufficient. I have to take down the faceless demon to get home? Save the original story to yourself! Let's just grow stronger and help the main character. That's how I'll get out of this world!
