The Ultimate Skill System: Absorb, Upgrade, Create, Transfer

I thought the MC will day after developing mana suffocation technique and use his powers in  another world. Disappointment.

The story's a simple one. Maybe even predictable. But it doesn't need to be a literary masterpiece. The story's simple nature is what keeps me coming back for more. MC's modus operandi is that if he can brute force it, he won't need to scheme, so he gets stronger, until he is strong enough to literally crush any and all opposition he faces.
