- Description from Novelupdates

Within the Huang Realm, a world where the era of divinities has ended and the era of immortals is nearing its waning years, exists the Buzhou Immortal Sect. And within the Buzhou Immortal Sect on Jade Peak was a disciple of the sect, Xi Tianyi. He was of noble birth, the only child of the Sword Empress who reigned invincible.

But the truth was that Xi Tianyi, was originally an ordinary mortal from Earth who suddenly woke up one day as in another world filled with immortals and demons. Under heavy pressure, knowing that his life is at stake to whoever is strongest, Xi Tianyi quietly cultivates in hopes of one day fearing no one and discovering the circumstances of his transmigration. But…

«You bastard, you stole my fiance!» Said a former genius who had lost all his cultivation.

«Bastard, pay with your life for the death of my entire clan!» Said a cultivator with blood leaking from his hatred filled eyes.

«What the hell?! I’ve been cooped up cultivating quietly so why are you guys suddenly finding trouble with me?! Besides, I’m only ten!» Cried out Tianyi in disbelief.

«Fine, if you want to make me your cannon fodder, I’ll step on your corpses for my ascension!»

The witch, Elonora Asil, has fifteen previous convictions.

And the transmigrator, Noah Park, had no intentions of being involved in the novel’s original plot of the dragon beheading the villainess. With that thought in mind, she abandoned her titles as The Wicked Witch and sought to live a long and peaceful life.

So she heads down to the countryside wrought with deep remorse for all her misdeeds. And all should be happy… or she thought.

“Please raise me!”

And so it would seem that she stumbled upon the heroine’s pet dragon — the black-haired kid that would turn ballistic and obsessive later on — imprinted the villainess as his mother. And to make matters worse, the male lead suspects her as the prime culprit of stealing the dragon.

“How long should I keep up with you?”

She thought he’d arrest her right away, but seems like the male lead was slowly becoming the dragon’s butler.

“Can I hug you?”

“No.”

“Then… can you hold me?”

The villainess believes that the dragon needs a bit of taming.

‘Oh, male lead, won’t you sign a life contract as a real butler?

He became a teacher at the best magic academy in the empire.
….For being mistaken for someone else.
