Beginning from the Waste Elixir Room to Reverse the Path and Become an Immortal

When Lin Fan opened his eyes and traveled through time, he was still a white-haired old man, but a fairy like a flower came to his door! "It's such a great thing, but if you don't take advantage of it, you'd be a bastard!" Afterwards, Lin Fan discovered that he had traveled through time with a golden finger and could turn waste into treasure! Waste elixir? What a joke! That is my best elixir! From then on, a gray-haired old man rose from the ruined alchemy room and became an immortal by going against the grain!
