I don't remember many details since it has been a long time. But I hope it is enough, thanks in advance. It is about a guy that is transported into a body in another world where they practice martial arts/ cultivation and I think they have beast as pets. He has a golden finger, I don't remember if it is a system, but it is like another dimension. This system transports powerful people inside this dimension, where the mc helps these people get even more powerful in exchange of treasures that he needs. The system allows him to know what is necessary for someone to evolve into the next stage, or how to cure poison/ mistakes of cultivation. The mc wears a mask and calls himself Curator. He will meet these powerful people in reality and pass of as the disciple of the Curator.
