I've Become the King of Villains in the Game - Chapter 268 - 194: Promotion! Magician Jack!

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!

The flower branch of dreaming to become a rabbit fairy: (/≧▽≦)/Chongchongchong!
But as soon as he wore the book, the flower branch that had not had time to turn into a human shape was picked up by Jinghuai, and the flower branch who wanted to turn back into a human shape had to stay beside Jinghuai every day, being quilted! he! trample! Smash!
After the rebirth, Jing Huai accidentally picked up a little bunny like a marshmallow, with ruby-like eyes, soft and fluffy bunny ears, and a fluffy round tail adorned behind him.
The scenery is cold and ruthless towards everyone, but she gently brushes her hair every day, feeds her scarce carrots, and gives her the sweetest spring water…
Until one day, Jing Huai put the flower branch on the head of the bed, touched her soft rabbit fur, and was about to fall asleep. Suddenly, the fur on his palm disappeared, and he turned into a girl with soft rabbit ears.
Jing Huai: “…”
Jing Huai rubbed her bunny ears, her face flushed with indifference, “Change back.”
Huazhi retracted his head into the quilt: “No, no.”
Carrots really suck!
