What's Wrong with a Paladin Knowing a Few Necromancy Skills?

Reborn + dark transformation + invincible protagonist + no saintly do-gooding

An age of universal class advancement, where monsters run rampant and order has been overturned.

In his previous life, Zhou Hao missed too many opportunities while trying to help the “moonlight of his heart” reach the top of the “Top 100 Mages” list.

In the end, the woman he adored betrayed him, and he died a gruesome death in the Abyss.

Reborn at the start of the class-advancement era, Zhou Hao no longer lives for anyone else. He uses his SSS-rank talent, [Undead Calamity], to build the strongest army.

And he hasn’t lost his original Knight class, either.

A mighty Holy Knight whose every attack is an undead skill!

He builds the ultimate dual-class character: a high-ranking knight wielding holy judgment in one hand, and an undead mage commanding vast armies in the other.

Endless reinforcements, blades pointed forward, a million soldiers, an endless tide of corpses. I am holy judgment, I am calamity!
