In his last life, he was a superstar that dominated the entertainment circle. In this life, he is a rebellious second generation wastrel.

Confronting the aunt and uncle who wants to seize the family property and getting rid of those slag friends who only know how to eat and drink…

(A cruel, merciless, inhuman, Prime Minister gong x (previously) a cute, naive, foolish prince shou)

As an alluring beauty, the Ninth Prince Qi Changyi inherited his mother’s looks, but was unfortunately a bit s*upid. Not only did he live in fear, even within palace walls, but he also merely lived as a substitute in his beloved’s eyes. Then, while being used and tormented, his delicate, pure heart finally burned to ashes.

Pei Zheng was the Prime Minister of the Imperial Court, a man of great status; he gained it all through the most ruthless methods. He was known for his cruel nature, but gradually, he became close to the unfavored ninth prince.

“Your Highness, just now, at court, who were you looking at? Huh?” Pei Zheng squeezed the small man’s delicate little chin.

Qi Changyi’s eyes were misty with tears of pain, “I, I wasn’t.”

“Stop trying to seduce others.” Pei Zheng’s voice was frigid. “Otherwise, I’ll make sure that General Zhao, for whom you pine, dies on the battlefield!”

He thought he had a firm grip on this little fool, but he could’ve never imagined that one day, this little fool would leave his side carrying a broken heart.

“Brother Pei, I’m leaving now, you should be happy.”

With scarlet eyes and a heart burning with obsession, he searched everywhere, but found no trace of him.

“I won’t, without you, I’ll never be happy again. Your Highness, where should I go, how can I bring you home?”

1v1, happy ending! But the path leading up to it is laced with sweetness and cruelty.

I have given up power that can make the strongest of men tremble. I bore scars very few can imagine; loved women, very few had the gall to talk; and tread paths with chaosfiends.

“And I'm still standing.”

Gale was summoned into a mysterious world of magic and monsters for no particular reason. Thrown into squabbles of beings vastly higher than him, Gale strived to make a place for himself in the vain dream of immortality and a better world.

That was six years ago.

Beaten and battered from years of brutal war, Gale finally had enough and resolved to start over a new peaceful life in a totally unremarkable town with his trustworthy companion, Vale. Give up the weapon of slaughter and take up a hoe? That seemed like a fine deal to him.

Unfortunately, the valley wasn't as unremarkable as he thought it to be. Dictatorial governing bodies, suspicious practitioners, an exceedingly unwelcoming guest, and a secret that would change the entire world, all impeded his peaceful life. Gale will need all his mental stability to keep his temper in check, lest he brutalises his way out of trouble. Again.
