[Setting Party] [Villain] [No heroine]

I am proficient in a hundred arts, and I know everything from refining elixirs, refining weapons, laying out arrays, drawing talismans, and raising spirit plants and beasts. However, to display skills, one must have natural materials and treasures.

Hehehe, I see that you are a treasure, can you let me refine it properly and make sure that everything is used to its full potential, with elixirs, weapons, talismans, and medicines, and everything else is available...

[Chinese Cthulhu + Bizarre Cultivation + No Female Lead + No System + Not Brainless] (Low rating because few people have read it) (Due to its vast world-building and complex settings, the early stages require setup, resulting in a slower-paced plot. Enter at your own risk if you mind this.) When I opened my eyes, I saw a bizarre stone statue I had never seen before. An old woman with yellow teeth, claiming to be my grandmother, was stirring inside my stomach with a strange knife. She was carving my bones. "Child, with spiritual roots, you can become an immortal," she told me. "Become an immortal? Become what kind of immortal?" I cried out in fear, looking at the tentacled monster. "No! I don't want to become that kind of monster!"

[Ding! Host's strong desire for change detected. Defective version of the Groupon System activated!]

[Three "junk" items of the same grade detected: broken animal bone, rotten medicinal residue, and incomplete talisman. Should they be fused?]

"yes!"

[Ding! Fusion successful! Congratulations, host, you have obtained one "Mortal-grade Low-level [Body Tempering Pill]"!]

What? What others see as trash can all be transformed into treasures in my hands?

Then wouldn't this endless mountain of garbage be my supreme treasure trove!
