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 living creature was digitized and awaited the endless slaughter and torture of the players from other worlds.Yi Zheng, who had become a mob rabbit in the Beginner's Village, decided to lead a group of rabbits. They sprinted across the grasslands, did crunches, bench-presses, rowing, and swimming etc.A year later, when the players descended, they saw more than just a group of small monsters.They saw an army of terrifying, demonic, muscular rabbits!The Rabbit King sitting on the throne high above waved a carrot as he threatened, “From this day forth, don’t even think of leaving Beginner's Village!”

10 billion people in the world traveled through the apocalypse to survive, but the protagonist directly turned into a zombie after crossing…

In order to survive, he opened the novice gift bag.

Got the trash skill: ?Xingchang?br>“?Xing Changhe? After eating alien creatures, you can get additional experience points. If the ingredients are fresh enough, there is a chance to get this biological skill.”

…

Um.

Really useless.

Alien creatures are full of poison, and the taste… is extremely unpalatable!

Eat alien creatures to gain skills?

That is courting death!

Such rubbish skills, after all…

Etc., etc? !

“Ding, you ate the Lion of Ice and Fire, gained 5800 experience points, and the skill Flame Body.”

“Ding, you ate the Wetland Poison Dragon and gained 180,000 experience points and skill dragon scale skin.”

“Ding, you ate the true ancestor of vampires…”
