The fantasy power-progression novel Ascension has two main characters: the male lead, Yan Duoqi, and his master, Sikong Ming.
Both have a grudge against Yiwei Sect.
Yan Duoqi's family was destroyed, while Sikong Ming was once a demon revenant raised through dark arts by Yiwei Sect and subjected to endless torment.
After reaching the height of cultivation, Sikong Ming leads his disciple to exact revenge. Yiwei Sect unleashes its newly raised Demon Revenant Emperor, but Sikong Ming easily subdues him. It's one of the novel's most satisfying moments.
Fei Ruo has just finished her monthly exams and plans to listen to a novel to help her sleep. Before drifting off, she hears:
"Sikong Ming grips the Demon Revenant Emperor by the arm, holding him up as casually as a kitten.
With a faint, knowing smile, he says, 'All demon revenants under the heavens originated with me, born from my flesh and bones. So what if you're the Demon Revenant Emperor...?'"
Fei Ruo wakes up and discovers she's transmigrated into the unfortunate Demon Revenant Emperor.
Someone is holding her as she sways in the clouds, like a dried fish dangling in the breeze.
Beside her, the strikingly handsome and tragic demon revenant, wild and carefree by nature, holds her firmly and gazes nonchalantly at the Yiwei Sect cultivators across from him, who are white with terror. "So what if you're the Demon Revenant Emperor? When you see me, you still have to call me Dad."
As soon as the words leave his mouth, everyone sees the Demon Revenant Emperor, born vicious and bloodthirsty, throw his arms around Sikong Ming and cry passionately, "Daddy!"
Sikong Ming: "..."

A certain mage once met a pair of master and disciple burdened by a blood feud while traveling the world.
Mage: "When will this cycle of revenge end? Why not let it go and avoid creating more karmic burdens?"
Master and disciple: "Then let the karmic burdens come!"
Unable to persuade them, the mage gave up.
Who would have thought that years later, the mage would run into them again, both with tearful eyes: "The karmic burden really came!"
Sikong Ming: "She's spoiled and loves making a fuss. Her temper is awful, and she spends money like water. She doesn't respect her old man's feelings at all."
Yan Duoqi: "She's obsessed with looks, flirtatious and fickle. She's attracted a whole crowd of unwanted admirers and even uses me as a shield, so wherever I go, my rivals pick fights with me."
The mage sighs. "In that case, why don't you two sever this ill-fated bond?"
Sikong Ming and Yan Duoqi: "Impossible! Don't even think about it!"
Theme: A healthy, beneficial relationship takes effort from both sides.
