Return of the Legendary Runesmith - Chapter 13 - 12- Repay

Where there is light there shall be darkness

Hero? Nahh I'm the demon.

In a world where the demons are looked on as the incarnation of evil, the human-demon war raged on across the whole continent.

The Seraphims, protector of humanity, and the Demon lords who rule across all demonkind. Amidst all the chaos, Simon was reincarnated as the lowest ranking demon noble.

A brutal world where the strong feeds on the weak, eat or be eaten, kill or be killed. A demon far off from humanity….a dream unfulfilled in his previous life will be achieved in this life. Taking on the moniker of Laplace, he destroys all his enemies and rise over them.

A hero must be compassionate, selfless and courageous.But that isn't all. Because a hero must also be powerful.In this world, power is everything. Strength decides who gets to save lives and who's left with community service. That’s why I was nothing — a rank 50 E-Class reject, skating through the streets, saving what little I could while the real heroes battled gods and monsters.Then one day, I died. Almost.Dragged into the abyss, I was given a second chance: the Forever Core. An armor that evolves. A system that never stops adapting. Every battle, every hit, every mistake, I come back stronger.Now, the monsters that once crushed me can’t kill me the same way twice.I must adapt. Evolve. I must grow stronger and fight harder. Because humanity is worth fighting for.Even if I have to burn every villain alive to prove it.

System, “You have a sickness. Moreover, you’ll have one in every world.”

Hao Ritian, “…”

System, “What’s wrong? Is there a problem?”

Hao Ritian smiled, “No, there’s no problem. I was just a bit excited.”

System, “…”

That smile intensified the system’s feeling of ominous foreboding. It has had this premonition since it learned the name of its host. Now it only prays that this is all its imagination!

Ps: Protagonist shou 1v1, the gong is always the same person.

Transmigrated Become Sukuna, but the host is Yukinoshita Yukino?“Ryomen Sukuna? The strongest sorcerer in history? He’s just an ordinary person born in a time without me.”Hayashizaki stood in front of Ryomen Sukuna, looking at him with a playful expression.“On my left is the 'Little Yukinoshita,' a possessor of multiple techniques, easily wielding both the Limitless Cursed Technique and the Ten Shadows Technique; on my right is the 'Big Yukinoshita,' who has awakened a unique modern technique, no less powerful than me. As for slashing techniques, those are just our basic attacks.”“So, tell me, how do you, Sukuna with 15 fingers, plan to deal with this?”Ryomen Sukuna stared at the black-haired young man in front of him, whose cursed energy was identical to his own, dumbfounded.
