The CP is undecided. It may be no CP, or there may be a CP.
After suffering countless abuses, the villain Yu Zhi finally turns evil and decides to destroy the world. But his sect's elders strike him with all their strength, and he falls off a cliff.
He is reborn in despair, determined to destroy this land, but by a twist of fate, he ends up taking a master.
There's just something strange about this master. She speaks and moves at a snail's pace, and even when she hits him, she does it slowly.
It isn't until much later that Yu Zhi discovers his master is a demon cultivator, and a tortoise demon at that!
And the reason he didn't find out sooner is that his master is too lazy to even transform back into her original form!
A little scene
In the mountains on a summer day, Jiang Yunlan gazes toward the morning light. "Mm, the sun."
Jiang Yunlan stands with her hands behind her back, her pale green skirt swaying in the breeze, her eyes narrowed toward the morning light. "Mm, the sun..."
Yu Zhi puts away his sword, wipes off his sweat, and jogs over to his master, asking with concern, "Master, are you getting too much sun?"
Jiang Yunlan looks toward Yu Zhi, her eyes unfocused, as if looking at him or perhaps at something behind him. "They're coming..."
Yu Zhi is startled and immediately turns around. Several men in black leap out of the grass, and the fight begins at once.
Jiang Yunlan, however, pays no attention at all and makes no move to help her disciple fight.
After Yu Zhi has knocked all the men in black to the ground, he returns to Jiang Yunlan.
He sees that her skirt has been cut by a sword and drops to one knee in remorse. "Master... I'm sorry I didn't kill them quickly enough. I ruined your skirt."
Jiang Yunlan stares coldly at her torn hem. "Pull!"
Yu Zhi's lips tremble as he looks at Jiang Yunlan. "Master, are you calling me trash?"
Jiang Yunlan falls silent, as if confirming it. "..."
Yu Zhi looks at the scene before him and feels even more aggrieved.
The spotted dove senior brother, who watched the whole thing from the sidelines, looks at his nephew disciple, who has let his imagination run wild, and quietly explains the truth. "Don't you think your master was just making an observation? Like, 'Mm, the sun's come out!'"
Yu Zhi: "..."
After Jiang Yunlan and Yu Zhi stare at each other for the time it takes an incense stick to burn, she slowly nods. "Your senior brother is right. Also, disciple, your master has sunburn."
With that, Jiang Yunlan, born a tortoise demon, falls backward.
A benevolent smile still on her face.
Premise: Let the world slow down because of you
