Invincible, Starting from the Time When I Became an Immortal in the Abandoned Elixir Room

Traveling through the world of immortality, Xu Tian became a handyman in Fanshan Sect's abandoned alchemy room. The beginning is hell mode: poor spiritual roots and riddled with erysipelas. What's even more terrifying is that in this sect, no matter what your status is, your life is nothing. Fortunately, I got a mysterious black cauldron, which can refine all things and turn waste into treasure! Relying on the treasure, Xu Tian became an immortal as he clung on. A highly toxic waste elixir? Purify it and turn it into the best elixir! Scrapped spiritual treasure? Repair it and turn it into a peerless fairy weapon! Incomplete Kung Fu? Deduction and completion, pointing straight to the road. Many years later, at the top of the avenue. Xu Tian pointed at the enlightened powers and said with a smile: "Don't mess with me, I'm just a rag collector." "But if you block the way for me to collect waste, then you are non-recyclable garbage."
