Xuan Zhi descended to the mortal realm by heavenly decree to undergo a trial. The Fate Registrar wrote his destiny into a book titled "The Cultivation Furnace."
As the villain in the book, Xuan Zhi showed no respect for his elders, defied his master, and abused and punished his disciples at will. He even stole other people's cultivation for his own use, becoming a great demon whom every cultivator wanted dead.
In the end, the immortal sects joined forces to kill him and turn him into a cultivation furnace, to be used by those who came after him to cultivate and siphon his power.
Xuan Zhi: ...?
Isn't it better to be alive?
And... what kind of embarrassing destiny is this?
The Fate Registrar: "Just follow the plot in the book, and you can return to the Heavenly Court."
Xuan Zhi: "What if I don't follow the plot?"
The Fate Registrar: "The story will rewind until you fulfill your heavenly mandate."
Xuan Zhi closed his eyes.
He would lie flat.
After becoming the villain in the book, Xuan Zhi completed the tasks in his destiny book one by one.
Destiny book: Humiliate your nemesis.
Xuan Zhi used his sword to demolish his nemesis's demonic hideout, then insulted him. "You'll never find a wife."
The demonic cultivator, standing amid the ruins: "If I don't cut off both your hands one day, may I never be a man again!"
Destiny book: Make advances on your master.
Xuan Zhi snuck into his master's private bath and left a threatening message: "Your disciple Xuan Zhi was here."
His master, furious after emerging from his bath and finding his underwear missing, issued a notice to the entire sect: "From now on, Xuan Zhi is forbidden to come within three feet of me!"
Destiny book: Bully your disciple.
Xuan Zhi replaced his young disciple's cultivation manual with an erotic illustrated book and ordered him, "You can't go to bed until you've finished reading it!"
The obedient, well-behaved young disciple blushed and protested, "I'm not your disciple anymore! I'm going to report you to Grandmaster!"
Thanks to Xuan Zhi's efforts, most of the destiny book was finally complete, and he lay flat, waiting for the ending.
However...
His young disciple, who held a grudge against him, pointed at another disciple and asked, "Didn't Master say I was your favorite disciple?"
His master, who had always been strict and disapproving of Xuan Zhi: "Why haven't you come to ask me for guidance on your cultivation yet, my disciple?"
Even the demonic cultivator who had never got along with Xuan Zhi had started acting strangely. "Whose hand have you held besides mine?"
Xuan Zhi: ...?!
Xuan Zhi summoned the Fate Registrar and angrily slammed the destiny book down. "I want to become a cultivation furnace! No... I want to return to the Heavenly Court!"
