MC Necromancer: The Nation Builds Me a Mountain of Corpses

[MC + reporting powers to the nation + genius]

Su Tian transmigrates into a world invaded by demons and beasts from myriad races, awakening the talent of a Necromancer.

When he checks his Source World, he discovers that it is actually the game save from his previous life.

It is the familiar blocky continent, but survival is confined to a border just nine blocks wide.

Fortunately, his talent lets him control the creatures inside, and killing demons can also expand his Source World.

Expanding it by killing demons alone is too slow. He cannot wait, and neither can Huaxia.

So he makes a choice: cooperate with Huaxia.

Using items from his Source World, he gives Huaxia a fighting chance to defy fate.

In return, Huaxia develops paths to strengthen his creatures.

He sets a bed on the ground. A soldier guarding a secret realm lies down on it for just five seconds, and immediately feels refreshed, with his mental energy restored to its peak.

He uses bone meal to speed up plant growth.

Heavenly treasures appear with increasing frequency, and Huaxia develops rapidly.

Huaxia also lives up to his expectations, constantly strengthening his undead creatures.

Su Tian: I want my zombies to have huge muscles, and for some of them to even form sandstorm and frost domains.

Huaxia: No problem. The Biological Research Institute is on it. We'll inject them with Titan genes, as well as earth-element and ice-element beast genes.

Su Tian: I want...

Huaxia: No problem...

Su Tian: I... want to lead Huaxia in a counterattack against the demon realms.

Huaxia: No problem...

With Huaxia's specially enhanced creatures at his command, Su Tian sweeps through the nation's young prodigies.

That is, until he takes the stage at the World University Tournament.

Students from every country look at the undead legion Huaxia has equipped to the teeth and go pale.

Eagle Nation's prodigy: Since when did Huaxia have such a powerful Necromancer?

Sakura Nation's prodigy: Damn it, we can't even stop a single one of his undead!
