[Cool, aloof top x obsessive, rabid bottom]
When Ling Xuan was brought back to the sect by his master, he was still a baby who hadn't been weaned.
His master taught him to read and practice swordsmanship, indulged him unconditionally, and gave him the very best of everything.
And Ling Xuan often told his master, "I'm never going to take a Dao companion. I'll never leave Jade Clarity Peak. I want to stay by your side forever."
Later, those words became, "Master, you taught me so much and gave me so much. Why can't you give me your heart too?"
He was lovesick and crazed, lost in this one-sided love. "I don't want anyone else to take your attention away from me. I want you to be mine alone, forever!"
So he wanted to have a child with his master, to keep his gaze fixed on him forever.
Yun Yi could never understand why the most obedient, brilliant, and talented disciple he had raised with his own hands was so intent on getting into his bed.
That year, in the inner hall of Jade Clarity Palace, Ling Xuan climbed down from the bed of Venerable Huayang, his clothes in disarray. His beloved disciple knelt on the cold floor. "Master, I love you. Please..."
The disciple used force to take his master.
In answer, he received nothing but icy snowflakes and a resounding slap.
"Stop saying those crazy things!"
Ling Xuan knew that he would never get his master's love. There was no way he could.
If that was the case, then he would leave behind more hatred. That was what he had in mind when he climbed onto his master's bed.
The senior disciple of Jade Clarity Peak was expelled from the sect for defying his master and fled to the Demon Realm, where he became the dreaded Northern Yin Demon Lord.
The world thought that Ling Xuan's descent into depravity was an act of desperation, the last thing he could do when he had no way out. But he knew the truth: only by becoming a demon cultivator could he make his master look at him again.
Many years later, Ling Xuan was locked away by his master in the prison of the Nine Heavens Exquisite Pagoda. As before, he pleaded humbly for his master to open his eyes and look at his wounds, and at their child.
But Yun Yi was unwilling to look, and afraid to look. In his life, he had killed many people and committed many wrongs. The one he regretted and blamed himself for most was raising a disciple like Ling Xuan.
He often sat alone in solitude, recalling every little moment of Ling Xuan's childhood. Which step had gone wrong? When had it happened? What had he done to make his beloved disciple develop such feelings?
As expected, he was not a worthy master.
