Stealing talents Because I Can

An unconfident but smart and cunning boy reincarnates in a cultivation world where he has the power to steal the talent of anyone weaker than him. Follow him on his journey to conquer the world, using his system which gives him a lot more immoral skills. ---------------------------------------------------------------------------- A bit clearer here. The Mc is unconfident, but also ready to step on anyone to survive and achieve his goal. The skills he will receive will be more immoral, like stealing talents but also others like making someone his slave or using other people to strengthen himself. Basically, he will be a demonic cultivator. On an R18 note, I am not sure if this will have R18 content but I am leaning on no. And if it will have r18 content, it will be like one sentence but never full-out smut scenes. If you have any ideas or constructive criticism, please tell me. I would appreciate it a lot.
