Manual of Wanfa

It's impossible to become stronger, and no one can beat him in a fight. Fortunately, there are many cute girls with big legs around him to hug, and with the invincible golden fingers, he can barely survive. The people in the other world are very nice.

It's actually just a series of various stories that happened while the protagonist was searching for memories in another world.
