Marvel Ultimate Gacha - Chapter 7: Fisk End

Xu Yuan transmigrated to a parallel world where everyone became lords. Initially, he thought he would be a lord too. To his surprise, he became the Dark Demonic Dragon, a starter hero awaiting to be summoned by a lord. He also awakened the Dragon God Cultivation System.

[Transformation of the Dark: You can level up quickly by staying in the dark.]

[Slumber of the Dragon God: For the Dragon God, sleeping means residing in the dark.]

[Rejuvenation of the Demonic Dragon: You can revive using the power of the dark. Your basic attribute points will increase every time you revive.]

[The Blade of the Hidden Wings: This is a dark attribute AoE skill. It can annihilate all enemies within the area of effect.]

[Unlimited Devouring: The skills of your enemy shall be yours now. Unleash this skill to devour your enemy and acquire their skills.]

…

Su Wan, a beautiful lord, had no doubt that she could easily become the most powerful lord in the universe.

She felt her heart beating fast when she first saw her starter hero dazzle amidst the flashing summoning light.

Unbeknownst to her, her nightmare was about to unfold.

While other heroes devoted themselves to training day and night in order to level up, her hero goofed around and showed no effort to improve himself.

While other heroes charged into the enemy’s base and valiantly killed off their foes, her hero hid in their base and slept soundly.

…

As time passed, Su Wan slowly discovered that there was more to her hero than met the eye.

One day, Luo Jian woke up from his sleep and found himself in a locked chamber where the door and window were all sealed. A note with a few lines written on it was tacked to the wall: “Escape from this room within an hour, otherwise, you will die.”

- Description from Novelupdates

Ming Liuyi transmigrated into a novel she had read, and to make matters worse, she was placed into the body of the novel’s antagonist who shares the same name. The original Ming Liuyi, bullied into marrying a cripple, decided to abuse the rich male lead, Yao Zizhou, until he went into a vegetative state. Ming Liuyi knew she had three months of safety before Yao Zizhou woke up and took his revenge. But for some reason, she was drawn to him, and when she touched him, her spiritual energy began to stir.

No one suspected that Yao Zizhou would actually still be perfectly aware of his surroundings, though he couldn’t move. He continued his days in great confusion when his arranged wife from hell was suddenly replaced with a sweet, nice girl, who actually cared for him dutifully and spoke to him with gentle words. It aroused his curiosity, but right before he could wake and see her, she fled. Yao Zizhou huffed in annoyance. There was no way he would let her escape his clutches.

I returned to Earth as the invincible Knight King. But the Gods came with me.
