[Probably a short story]
1.
Bai You and Bai Mo are fraternal twins.
When they were twelve, an immortal took Bai You to the cultivation world, leaving Bai Mo to wait for him to fulfill his promise to return.
Bai You was a liar. He was never coming back.
From being a young lady of the General's residence to becoming a beggar among the refugees, Bai Mo kept reminding herself of this.
Amid the turmoil of war, corpses littered the land, and Bai Mo eventually caught the plague.
There was no cure. She had little time left.
At death's door, Bai Mo's blurred vision fell upon a young man who looked strangely familiar.
Bai... You.
"Save her."
A sneer, full of contempt and derision, answered her: "She's only a low-level cultivator. What makes you think you can order me around?"
"I can trade my body for it."
"That'll do." A man's voice agreed to the bargain.
Trade her body? What kind of deal was that?
It wasn't until Bai Mo reached the cultivation world that she learned from others:
Her own brother, Bai You, was the cultivation world's most sought-after bottom.
He was a furnace cauldron, regarded by cultivators as the lowest of the low.
Anyone could humiliate him.
2.
The Immortal Venerable's new female disciple was a genius, and no one could wield the Yanjing Sword better than she could!
Her brilliance drew a crowd of disciples to watch her initiation ceremony.
But as soon as she received her sect token, she left her newly accepted master behind and headed straight for another Venerable's abode.
With one sword strike, she split Mount Juyu open.
Before the other spectators could even see what was happening, Bai Mo used a spell to dress Bai You and pulled him away from the Venerable.
"Junior Brother, how did your new disciple become so ill-mannered?"
"Nephew, you can accept a master, but you can't steal your martial uncle's things..."
Before the Immortal Venerable could respond, the Yanjing Sword had already pierced the Venerable's chest. Blood sprayed everywhere, cutting off the rest of his words.
"Bai You."
"He is my brother, Bai Mo's."
"He's not your plaything."
"The newly ascended Demon Venerable, Bai Mo. Remember that name."
"You will die by my hand."
3.
This is a brainless cultivation-world story about a universally sought-after bottom.
The protagonist, Bai You, is abused by all kinds of tops until the scum tops come to their senses and try to make amends. By then, Bai You has lost himself and sunk into the mire, so he forgives them all with ease.
The ending is happy.
He never sees the light again.
But the story takes a turn when a demon from another world is reincarnated into it and refuses to let things unfold that way.
She will change this world.
If she succeeds, the cultivation world remains.
If she fails, the cultivation world can start over.
Content warning: There are too many things that may be upsetting to list them all.
