In order to save Taoist lover Lin Wanyi, Qingchi took his own innate Taoist bones in the Valley of Burial Love, and his cultivation was completely ruined.
On the day of her ascension, she cut open the bones with her own hands and presented them to the prince of the immortal world, Yun Ye, laughing at him for being a human being and derailing her century-long journey to immortality.
When he fell into the devil's abyss, he used his soul to carve a counterattack blood curse: "When I come back, I will use everything you cherish most to sacrifice my hundred years of insanity."
Three thousand years later, the demon king "Fen Qing" sits in the abyss.
In order to seek peace in the fairy world, they sent the prince and his wife as envoys to offer a contract.
He lifted his hood and smiled at his former love:
"I'll sign the contract—but I'll add three clauses."
"One, the fate of immortals and demons is reversed for three thousand years."
"Two, the contracting party uses his own soul as security."
"Third, those who betray their hearts and oaths... Will remain in the devil's abyss forever and suffer the punishment of being burned by the fire of karma."
When the contract is established, the immortal bones return to their places, and the demonic flames burn the sky.
Only then did he slowly tell the truth:
"Lin Wanyi, do you know that I have carved a century-old love spell on this bone?"
"Every time you use its power—"
"They are all igniting the flames of revenge for me..."
