MTL - Yu-Gi-Oh!: Underworld Boss, Cancerous Creator God - Chapter 119

In his old life, he was an assassin, invisible, efficient, and utterly alone.His only escape came from the pages of a fantasy novel, Crown of Thorns, and the character no one else seemed to understand: Lady Evelina D’Arclight, the proud and brilliant villainess fated to lose everything.After his death, he wakes up inside that very story, not as a hero, but as Cael Arden, a student at Eryndor Royal Academy. The world is just as he remembers it, right down to the woman destined to fall.But this time, he’s not a bystander.With a lifetime of deadly skills and the knowledge of what’s to come, Cael sets out to rewrite the story itself, to protect Evelina, rise through the academy’s ruthless hierarchy, and change a fate written in stone.As alliances form and secrets surface, the line between fiction and reality starts to blur.And in a world built on power and prophecy, he’ll prove that even a villainess deserves her happy ending.

“He who bears the light of heaven and the rage of hell shall decide the fate of gods and beasts alike.”When the world shattered and stars fell from the heavens in blinding storms, a child was born—cursed with the power to either end the eternal war or bridge the gap between heaven and hell.Now, hunted by gods and worshiped by shadows, he must choose which side of his soul will burn brighter - light of heaven or fury of hell.

Emperor Gabela: Imperial legions are unstoppable on land.

Great Orc Chief: All the warriors of the tribe can count as ten.

Jade Realm Elf King: The forest ranger has never missed a shot.

Chairman of the Horn Bay Alliance: The alliance fleet is the undisputed ruler of the sea.

A mysterious organization: The prophesied era will finally come.

Paul Grayman: I am not targeting anyone. Everyone here is rubbish.

Start the journey of guns and cannons crushing the low-magic plane…

- Description from novelbuddy

He had crossed into the dark, ruthless Wizard World.Lucien found his system somewhat different from the usual golden finger.System upgrade points? Chip activation?None of these, but rather becoming a role model, transforming into a nurturing breeze:Teaching students knowledge, receiving advanced knowledge in return.Caring for and maintaining students, earning generous rewards.[Your student has mastered the Magic Potion “Kuru's Cough,” congratulations on acquiring the improved formula “Kuru's Cough - Enhanced”!][Your student has mastered witchcraft “Fireball,” congratulations on learning witchcraft “Greater Fireball”!][Your student has successfully crafted the wizard's tool “Pale Mask,” congratulations on acquiring the wizard tool’s manual “Revised Pale Mask”!]Initially, Lucien was resistant.But after experiencing what it was like to teach disciples and outdo them, Lucien felt he had completely transformed into the form of the master system.This thing, isn't it much more useful than something called Cheating Device?
