I hate being in pain, so I think I'll make a full defense build - Chapter 456

A top hacker was chosen by the Lord God to be reborn into countless worlds, always as an expendable villain.

With no free will, every world became a dead end. Every one of his lives ended tragically.

Finally, after wrestling control of the Villain System, this ace hacker decided to enact revenge. Even if his very bones were rotten, he’d choose to occupy the very heights of morality, if only on the surface.

Thus, he would change his fate as an abused slag.

Yan Sagawa is the top academic master in the world of Conan, known as a national treasure talent.

No one knows that he is actually a time traveler, carrying the most powerful Xueba system.

But he also has troubles recently, and he has awakened a second system — the Great Onmyoji system.

Whether to believe in science and become the father of all mankind or believe in theology to become the god who controls reincarnation, this is a question

. . .

After thinking for a long time, he decided that he wanted them all!

Conan: This is impossible murder! Is there really a ghost?

Sagawa Yan looked at the shikigami flying in the sky and smiled without saying a word.

Kidd: What kind of magic is this, how could you hide it from my eyes.

Sagawa said: This is science, you scumbag

- Description from novelbuddy

Usually when you possess a novel, you start in the city, but I fell into the forest.

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.
