The villain who rules the world

My name is Ammons. I am a villain. I can modify common sense and exchange various villain abilities as my own demon power through the demon system.
The holy wizard protagonist who was reincarnated from ancient times into a useless prince. Your magic is unmatched, but your fiancée is too shy~ Your master is very smooth~
And you are born invincible, a genius prodigy of the Duke's family, your swordsman maid is very fragrant! What, you are actually a little loli? Then take it all!
Like these reincarnations of Lao Deng, Long Aotian, the brave ones, etc., as long as I, Ammons, am around, you will suffer!
