Descent of the Demon God - Chapter 96: Core Refining Machine (2)

I made a deal with the Devil.Free of Charge.

More than ten years later, this sentence gradually spread in Elbaf Continent:

Never use magic to deal with tyrants, because you will find that he will return your spells to you thousands of times after being strengthened by countless magic specialties.

This is the story of a dragon-shaped self-propelled fort that keeps doing things in another world.

There is nothing that one magic can’t fix. If there is, then there are more. ——Izawa

- Description from novelbuddy

A chilling air swept across the desert as a figure in a black cloak and obsidian crown walked toward the advancing army of House Elyria.With a raise of his hand, the sun turned black, plunging the battlefield into darkness. The wind ripped away the sand, revealing an ocean of skulls, and from it, thousands of undead surged, surrounding the army.Blood spilled, and with each death, the army grew—undead rising even before their bodies hit the ground. The figure stepped onto the shoulder of a massive giant, its molten eyes burning as it crushed entire squads with a single swing.As the black sun set, only the general remained. Kneeling, he glared.“You think this will go unanswered? House Elyria is one of the strongest forces on the continent!”The figure smirked. “Your House will answer soon enough. I’ll be visiting it tonight.”With a wave, the undead surged, swallowing him whole.--After his death in an accident, Roye awakens in the midst of a dark sacrificial ritual, surrounded by hundreds of lifeless corpses inside the body of Roye Valdrin—a disowned noble, the forgotten younger brother of a ruthless villainess, and the discarded ex-fiancé of a destined heroine.Worse yet, he has transmigrated into the world of Valoria, a dark fantasy realm where humanity began reclaiming its place on the surface only eight hundred years ago, after living underground for millennia with no idea why they were forced to hide in the first place.A world where gods and ancient emperors still influence the living from their graves.A world where politics run amok.A world where evil hearts and questionable morality lurk beneath a beautiful facade.Could he even survive in such a brutal world?Core Bloodline Acquired—Special Inheritance Gained: Apostle of Death.(Rank- Unknown)Roye doesn’t know if he will survive, but he knows one thing: he’ll do whatever it takes. Messing with the plot, killing main characters—nothing is off-limits.If the world wants to destroy him, he’ll burn it down first.

To save a doomed fantasy world, I killed the main characters, then destroyed the game world, and fell into another timeline as the academy's top seat and rival to the protagonist.Now, I'm trying to save the world and steer it towards a better ending…But I'm the final boss.
