The shadow of the primeval self will hack

Zheng Lei was a transmigrator, but his fate was not very good. Not only did he not reincarnate into a big shot in the Primordial World, but he also did not obtain any powerful Dharma treasures. He only entered a small sect in the Primordial World. Because of his narrow meridians, his cultivation speed was extremely slow.

However, the Shadow Hack System that he had obtained by chance had completely changed his situation. Talent? What were those things? Was it edible?

I don’t have any aptitude or talent, but my shadow can level up in the fantasy world.
