- Description from novelbuddy

Before going to college, an ordinary high school student went to celebrate and got drunk. When he woke up, he found himself in a completely different world. There was a big sect, the approaching sect entrance examination, a slum where his body’s previous owner lived, and a shared memory about a missing young girl.

Lin Fan was transported to another world, into the body of a normal disciple. Given the environment he was in, Lin Fan faced the risk of being killed at any time. However, something was out of place.

Lee Seongjin, the strongest hunter who defeated the demon king.
He possessed the body of the pig tr*sh Third Prince, the Holy Imperial Family’s shame.

But the members of this family… there’s something strange about them?

‘Overpowered’ Holy Emperor.
‘Regressor’ First Princess.
‘Player’ First Prince.

Lots of trouble and lots of words
The story of the Holy Emperor and his children.
