I Rule Beneath the Abyss

Gu Chen transmigrates to a world where everyone changes class.

His father is a Holy Sword Warrior, the War King of the Northern Border;

his younger brother is a Dragon Battle Knight, a rare class.

As for Gu Chen, he was abandoned for eighteen years, suffered a life of poverty, and was treated as utterly insignificant.

When he finally makes it back to his family, his father sees him as a disgrace, his stepmother berates and insults him, and even the household servants look down on him.

After severing ties with his family, he successfully changes class to Summoner and gains a god-tier talent: Primordial Blood of the Darkborn.

[Primordial Blood of the Darkborn: Gain dark bloodline and the power of the Abyss]

Once his summoned beasts fuse with the dark bloodline, they can evolve into dark creatures!

[Bloodthirsty Bat] + [Dark Bloodline] = [Dracula]

[Incubus] + [Dark Bloodline] = [Nightmare Sovereign]

[Gargoyle] + [Dark Bloodline] = [Corpse Golem]

From then on, Gu Chen becomes an army unto himself, leading his dark legion to sweep through every obstacle and crush countless geniuses.

When the Abyss invades and a Demon God leads an army of foreign races into the world, his dark legion easily slaughters them.

Facing the trembling Demon God, Gu Chen smiles and says:

"You know Nidhogg, the Black Dragon of Despair? The one even the God King Odin couldn't defeat? Right, it's a dark creature too."
