Fantasy: I'm in a discarded alchemy room, but I can turn trash into treasure!

After being kicked away by his fiancée, the Holy Maiden, Qin Mo awakened the Qiankun Furnace.
Everyone says that a person with mixed spiritual roots of the five elements is a waste, destined to spend their entire life dumping medicine dregs in the alchemy room.
But no one knew that he could turn waste pills into spiritual medicines, refine broken weapons into magical treasures, and complete incomplete cultivation techniques into unparalleled divine arts.
Yunyu Palace treated him like trash and trampled him underfoot, so he turned all the trash in the sect into a ladder to heaven.
Later, Su Qingyi stood before him, her voice trembling, "Qin Mo, let's start over, okay?"
Qin Mo dusted off the cinnabar dust from his sleeves and smiled.
"Saintess Su, have you finished cultivating your Forgetfulness Mantra from back then?"
—You have abandoned me like dust, so I will let you see with your own eyes how this speck of dust can crush your sky.
