I Asked You to Be an Alchemy Apprentice, but I Didn't Ask You to Become an Alchemy God.

Chu Yan, who was reborn in another world, became the apprentice of a mysterious alchemist in order to save his brothers. Because he had no talent and was judged as useless, he could only learn to make alchemy, collect herbs, and help his master with odd jobs. Little did he know that the medicinal materials he collected were all rare and genius treasures. The first time he made an elixir, he made a high-grade elixir. His blood can also improve the level of elixirs. The little pets I collected before have become the demon kings in the restricted area. The apprentice he took in casually became the greatest animal trainer. Chu Yan himself also became a peerless alchemy god.
