MTL - The Twelve Zodiac Guardian Gods - Chapter 354 4 sacred beasts (on)

In the vast and boundless continent Cangtu, there were ancient sects governing the Ten Old Domains, unworldly immortal clans beyond the Blue Sky, and primordial demon gods dominating the dark abyss that together created a great number of brilliant stories over the long course of the history.

Hu Feng, a high school student, accidentally embarked on the road of modifying the world.

Upon meeting the girl who would become her adopted younger sister, the duke’s daughter Christina regained memories of her previous life. Through those memories, she learned that her new sister, Mishuli, was the heroine of a certain story. And though the story depicted a Christina who abused her sister, the real Christina turned into a siscon who spoiled Mishuli to no end.

The game spoilers turned out to be fake. The characters I gathered thinking they were heroes are actually all villains. In other words, I accidentally created a villainous organization.
