Immortal of Quick Transmigration, why are you blackened again?

As the only nightmare beast in the Three Realms, Lingyao was bestowed with immortality, but in order to atone for her sins, she chose to erase her memory in order to risk herself. Attack the heaven.
She went through one dream after another, and found the impoverished Yueheng Xianjun: she saved a certain president who should have been subjected to violence, but in exchange for a sentence: "Yaoyao, you saved me, I am yours, so—— You should be mine too."
Lingyao: What logic?
He is especially concerned about the prince who is pretending to be crazy and acting stupid. After accompanying him in the "fool seizing power" scene, he actually won't allow him to leave?But what about out-of-this-world quests?
It was agreed to help the prince heal his leg disease and then go his separate ways, but what does it mean that a certain prince finally regretted it?
……
In the end, Lingyao finally escaped death and returned to the fairyland, but... Yueheng didn't wake up? !
Later, what the Immortal Emperor was most worried about happened. Mozun led troops to capture Nantianmen.
Lingyao: What's going on?!
Nothing happened, it's just that Xianjun has turned black...
(Quick text, there is sweetness in the abuse)
