The Junior Heavenly Demon, Yeon Woon-hwi, was born without a dantian.

However, through dark arts and his shitty personality— er, preternatural ability, he became the junior lord of the Heavenly Demon Cult.

He was a man of many epithets:

‘Great Sorcerer of the Dark Arts’

'King of the Wandering Lost Souls’

But the people’s assessment of him was simple:

“If he smiles, run as fast as you can. His smile is a death sentence.”

“Catch his eye, for he shall provide you with lifelong protection. That is, if you can.”

He was living the good life when he was suddenly betrayed in a coup led by the vice-lord and elders of his cult.

“You seem to have forgotten what kind of person I am, Uncle. So die. All of you."

Using the holy relic of the first Heavenly Demon, he self-destructed, taking the traitors with him. And then, he opened his eyes to the most unexpected of places…

"I'm in the Tang Clan? And a branch family at that?"

He awoke as Tang Woon-Hwi, an illegitimate son of the Nine Dragon Branch Family, a subset of the Sichuan Tang Clan.

Will Woon-Hwi be able to find his master, bring together his scattered followers, and rebuild the Heavenly Demon Cult?
