The notorious imperial court lackey and the meritorious military general were well-known for their mutual dislike, a pair of arch-enemies set in stone. Who could have foreseen the unexpected change in the winds of heaven: the general injured on the battlefield, both legs disabled, and even forced by the emperor to marry his nemesis.With one marriage edict, two people with mutual hostility are forced to marry and live under the same roof. Yet after these long days together, they come to the realization that this fellow is not truly devoid of any saving grace/unattainable and high out of reach.

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.

Every drop of this family bloodline is stained with sin. They are the embodiment of contradiction; calm yet maniacal, with great memories yet often forgetful. They pledge themselves to their dreams yet often compromise, are angels that are also devils… It’s why I hate them. And also love them.
