After Master whipped my immortal bones, Demon Lord cried and begged for reconciliation.
I was a proton offered by the demon world to the fairy world, but I became the closed disciple of the supreme being in the fairy world.
When he taught me swordsmanship, he always used a jade ruler three feet away from me, and when he marked my homework, the cinnabar did not stain my rolls.
Until the day of the battle between immortals and demons, I blocked the fatal blow from the demon father for him.
He held me in my blood-stained white clothes and removed my immortal bones in public: "From now on, you and the immortal world will owe nothing to each other."
A hundred years later, the new king of the demon world ascended the throne, and he knelt in front of the palace with a letter from the immortal world.
I stepped on his back with my bare feet and chuckled: "The pain that the Immortal Master suffered from his bones back then will be repaid twice as much today."
But in the middle of the night, I found him kneeling beside my bed, holding the immortal bones that were broken into powder and begging softly:
"Li'er, can you come back and be my little apprentice?"
