"Immortal Emperor" is a harem-oriented, overpowered cultivation power fantasy. In the book, Long Aotian has his spiritual roots crippled by the demon clan and is dumped by his fiancee, only to awaken an ancient inheritance. He rises through the ranks, slays demons, wins beautiful women, and ultimately crushes the demon clan's invasion plot, becoming an Immortal Emperor with countless beauties at his side.
After dying, interstellar fugitive Pei Huaiyu transmigrates into a book at the moment Long Aotian is dumped by his fiancee, and becomes bound to the Villain System.
The System demands that he play a series of doomed female villains, including Long Aotian's wicked fiancee, and help Long Aotian follow the plot to atone for his sins. Otherwise, the Heavenly Dao, the will of the world, will punish him.
Pei Huaiyu, who has always done as he pleased: ?
Why should he atone? He'll just cut Long Aotian down right now.
Pei Huaiyu was about to draw his sword when he met Long Aotian's fierce, wolf-like gaze.
He stopped, his eyes lingering on Long Aotian's excessively handsome face, and gradually grew intrigued.
That night, Long Aotian, a straight man from a harem story who had never made a sound despite being covered in wounds, watched in horror as his fiancee lifted her skirt.
The System let out a shrill scream: "This is wrong! Why are you a man?!"
.
The next morning, Long Aotian ran off with a limp. Pei Huaiyu lowered his eyes and bandaged the wounds he'd gotten fighting Long Aotian, while the Villain System, which had bound itself to the wrong person, fell apart.
System: "Just you wait! Long Aotian is the son of the Heavenly Dao! He'll repay today's grudge a hundredfold one day, and if you stray from the plot, the Heavenly Dao won't let you off either!"
Pei Huaiyu raised an eyebrow and watched the heavenly lightning streaking toward him from the horizon.
Son of the Heavenly Dao? Repay him a hundredfold?
He'd like to see just how high the heavens reached.
Pei Huaiyu simply made use of every villain secret identity in the System. Braving the lightning tribulations, he took on aliases and stayed by Long Aotian's side, following the plot and leveling up with him to save himself, while also giving Long Aotian and the Heavenly Dao a taste of how cruel the world could be.
Long Aotian was plunged into a nightmare of cross-dressing powerhouses.
First he met a gentle, understanding beauty, then a seductive demon-cult enchantress, then a cold and ethereal goddess... Each of these female cultivators was beautiful in her own way and treated him wonderfully, accompanying him through one crisis after another. Yet every single one lifted her skirt just as his heart began to flutter, then used her overwhelming strength to forcefully take him when his worldview shattered.
How dare they humiliate him like this!
Long Aotian went from refusing to back down and fighting Pei Huaiyu, to discovering by sheer coincidence, in terror, that every cross-dressing powerhouse was the same person, to dreaming of Pei Huaiyu dressed as a woman and having erotic dreams about a cross-dresser lifting her skirt and bending him over.
Forget building a harem, even his straight-man identity was on the verge of collapse.
Now it was the Heavenly Dao's turn to fall apart.
.
After battling Long Aotian and the Heavenly Dao back and forth for countless rounds, dressing as a woman and accompanying Long Aotian from being hunted to becoming the greatest under heaven, Pei Huaiyu fell for him and softened toward him before the decisive battle with the demon clan.
He still didn't know that Long Aotian had figured out his secret identities. He only felt that forcing a straight man to turn gay all the time was pretty unethical.
On top of that, the System and the Heavenly Dao had finally been beaten into submission. They begged and pleaded, promising him a chance to come back to life if he would log off. Pei Huaiyu decided to turn over a new leaf, tell Long Aotian his final wishes, leave him an inheritance, and then depart.
Long Aotian seemed to sense something.
The straight man who always ran away whenever he saw Pei Huaiyu began awkwardly approaching him, trying to find ways to make him stay and tossing and turning over him at night.
In the end, Long Aotian confessed to one of his secret identities, swearing he would make a name for himself and come marry him, then stammering that he shouldn't leave.
Pei Huaiyu was a little moved.
If Long Aotian hadn't also confessed to his second secret identity, swearing he would come marry him.
Then there was the third, the fourth...
Long Aotian had come to terms with himself and admitted he was gay, so he confessed to every one of Pei Huaiyu's secret identities, without even changing his lines.
Pei Huaiyu was surrounded by black fumes.
--This lecher's gone gay and he still wants a harem!
Log off, my ass! He's not getting away with this!
.
The plot had just reached the point where Long Aotian took revenge on his fiancee.
According to the original story, Long Aotian would discover that his fiancee's family had colluded with the demon clan, sever their ties with a single strike of his sword, and become the undisputed leader of the righteous path, leading the immortal sects into battle.
Pei Huaiyu had prepared for a long time. He was just waiting for the moment to confess to Long Aotian that the cross-dressing powerhouses who had tormented him all these years had always been him, then fight this scumbag to the death.
But to his surprise, Long Aotian abandoned his revenge and gave up fighting the demon clan. He took Pei Huaiyu's hand and earnestly said that now that he had made a name for himself, he had come to marry him.
He wants to add even the wicked fiancee he's met only once to his harem?!
Pei Huaiyu could take no more. He tied Long Aotian up on the spot and beat him in bed for three days and three nights.
After locking him up, Pei Huaiyu removed all his makeup and pointed his sword at the scumbag's heart, his gaze turning cold. "Everyone you confessed to was me. What do you have to say for yourself now?"
Long Aotian stared at him, back in men's clothes, for a long moment, then said softly, his ears red: "I knew they were all you. You're the one I want to marry."
"Clang--"
Pei Huaiyu dropped his sword in shock.
The System and the Heavenly Dao both shattered.

A wicked, fiercely protective beauty who is a powerful cross-dresser as the gong x a straight-laced, instinct-driven, pure-love Long Aotian who is turned gay as the shou
Cross-dressing powerhouse means a powerful gong who dresses as a woman.
In the shou's straight-man universe, anyone wearing a skirt is definitely a woman, so he gets shocked by the gong again and again. He can't recognize that "this female cultivator is a man," but once the skirt is lifted, he realizes that "this man is the gong."
It basically goes: A female cultivator must be a girl, no way she's that pervert -> What gender is this person in a skirt? -> This person is Pei Huaiyu again!!
A one-on-one story with both leads' first times. Beautiful gong, handsome shou, half a year apart in age, younger gong. These are the author's preferences, so if they're not yours, proceed at your own risk. Posts that split the pairing, reverse it, dream up alternatives, pick fights, or provoke will be deleted. Thanks for understanding.
