One Piece: King of the World - Chapter 27 - : Shinsō Confronts Rayleigh!

He is high above, the mysterious and terrible King of the Wild. With one glance, he can see people’s romances. He hates women to the extreme, but at his first glance of her, he dotes on her and spoils her.
She is a humble transmigrator, a miracle doctor who doesn’t care for the many handsome men around her. She only wants to become strong, to be worthy of that god-like man. But when she’s finally sure of her feelings, she finds out she’s already been married for years…
……
When wronged：
She uses strength to hit the big handsome iceberg-like man in front of her eyes. “People say that I’m not good enough for you, but it is you who is an old cow eating tender grass!”
A man seizes the main point and laughs like an evildoer. “This husband has to eat the grass to confirm if it is tender or not!” He puts out the red candle……
……
The world says：
The barbarian king has no heart and has no passion.
A pregnant woman very miserably thinks,” If he has no passion, then who is responsible for this big belly?”

He is a threat to her existence.

A hot-blooded dragon of Royal blood, King Malachi is taken hostage by the humans he despises so much. Deprived of his freedom, he is imprisoned in a dark cave, his rage growing with each day of torture and humiliation. The only light he sees comes in the form of a human female, offering her care. A woman who makes him burn with equal fury and desire. A woman who has no place in his heart or mind, for only one thought sustains him.

Vengeance! And even if her kindness softens his heart and her touch sets his body aflame, she will not be spared his wrath. Because once he breaks the chains of slavery, he will burn down her whole world.

She is the key to his freedom.

The cold-hearted princess Ravina is a woman with a mission. Eradicate the dragon race from the face of earth. But when she finds out that the very creatures who killed her parents could also be the ones who kidnapped her sister, she has no choice but to change her plans.

To find her sister, she must get closer to the creature she despises. But things don’t always go as planned and soon Ravina ends up finding more than she bargained for. Caught in a battle between humans and dragons, love and hatred, trust and betrayal, Ravina must make every choice with caution. And with every step she takes closer to the fiery beast, she risks melting the ice surrounding her heart and being consumed by the flames of fury and passion.

Even though Gu Yunxi was created from the accumulation of the resentment of souls, there was not a bit of ruthlessness nor cruelty in his nature, only a desire to cultivate. Just as he achieved his human form, he was sent to reincarnate. Under the control of Heaven, he experienced life after life of suffering, dying a terrible death every single time. After thousands of reincarnations, thousands of terrible deaths, he finally accumulated enough power to escape from the Laws of Heaven. He swore to get revenge on this blind Heaven’s Law that’s unable to differentiate good from evil.

So what if it’s the Heavens? He will stir up the rights and wrong, the good and evil!

You want me to accept this life and die, but I just won’t! I want to live, to rebel against the heavens, to reverse this joke of a destiny!
