Wanting to Surpass the MC with the Greatest Harem.

A man transmigrates as Dominic, an extra in a game. Being chosen my the Lords to defeat the MC of the game, he has to level up to the greatest ever limit. He has to defeat the MC but he needs some women by his side to help him. He needs the greatest harem. Exploiting them he gains not just a harem but also copies their special abilities. Just like a game, he gets to take down every member so as to face the MC. Please read on. I may not be frequent in updating but if I notice a good start I could release frequent chapters. Also support me with power stones.
