My name is Ammons, I’m a yellow-haired guy. I can modify common sense, and I can also exchange the abilities of various male protagonists in the other world as my own demon power through the demon system.The holy magician protagonist who was reincarnated from ancient times into a good-for-nothing prince. Your magic is unmatched, but your sister is very smooth, your younger sister is also very smooth, your fiancée and master are also very smooth, but now they are all mine!And you are born invincible, a genius prodigy of the Duke’s family, your swordsman maid is very fragrant, awesome! What, you are actually a little loli? That makes you awesome too!Like these reincarnations of Lao Deng, Long Aotian, brave men, etc., they are all awesome!
