Su Li was once the youngest medical immortal in the immortal world. Because she refused to remain silent about an unjust case, her immortal power was sealed away and she was cast down into the mortal world. Hundreds of years later, she hid in a small mountain village at the foot of Qingyin Mountain, pretending to be mute and practicing medicine without caring about worldly affairs. Until a hunter covered in blood was carried into her yard - he was carrying a domino engraved with ancient animal patterns, and traces of long-lost forbidden arts remained in the wound.
At the same time, a nine-tailed fox demon who had been practicing for thousands of years found the reincarnation of his benefactor - a down-and-out demon slayer who was too poor to even buy talisman paper to repay the favor of saving his life five hundred years ago. The four met because of an ancient forbidden weapon called the "Demon Refining Furnace" that can refine all things, and they were involved in a huge conspiracy that spanned the three realms of immortals, demons and humans.
From the mountain village to the heaven, from Kunlun to the Northern Territory, the two women, with their own bonds and beliefs, uncovered the truth layer by layer that had been concealed for thousands of years. Underneath Suli's gentleness is a sharp edge that has been sealed for hundreds of years, while behind Feiyu's publicity is the blood feud of the nine-tailed fox clan being exterminated. They are not sisters, but they are the only ones who dare to give each other their backs; they appreciate and like each other, but they will not become lovers - some deep feelings do not need to be defined.
When the mastermind behind the scenes finally surfaced, and when the source of the forbidden technique pointed to the highest point in heaven, Suli placed the celadon vial with the master's name engraved on it in the courtroom, and said what she had not had time to say back then: "I am here to collect debts. Not with hatred, but with the truth."
Intention: Protection is more powerful than destruction, healing lasts longer than hatred - the real power is not suppression and refining, but protection and healing.
