[The world has seen the lingering evil in your heart]

[Would you like to be one of the nine demon kings of this world]

[If so what are you willing to sacrifice?]

In the heat of the moment, Damien made a deal with the world, that he would give up everything he owns, or do anything it wants, and in exchange, he shall be reborn as a new Demon King, and what the world required from him as payment was.

[In exchange for power, become a slave of the world, and act as an anti-body for all eternity]

At that moment, Damien agreed, but little did Damien know, that becoming a slave to the world meant he has to be its immune system, what that entail is, that anything that threaten the world must be destroyed even if he has to wipe out humanity, to save it, or assassinate historical figures to bring fort balance or even manipulating events that can potentially end the world, to save the world, this is the story of a necessary evil, not the story of a hero who cares for others.

(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.
