In Different World with Naruto System (WN) - Chapter 123: Demon clan

In a world where power is marked by glowing runes and monsters bleed through the fabric of reality, **Ryu** is nothing—an orphan with no name, no status, and no hope. Beaten down by nobles who wield their divine-given strength like a whip, he survives on scraps and stubborn defiance.But when a black rift—an anomaly unlike any ever recorded—appears in the dead of night, Ryu faces a choice: die a beggar, or risk everything by stepping into the unknown.Inside, he finds a nightmare. Kolasis, a legendary predator, hunts him through a twisted forest. The rules here are simple: kill or be killed. To survive, Ryu must forge himself into something sharper than the claws of monsters and crueler than the nobles who cast him aside.Yet the rift has its own secrets. The same power that could make him a legend might also break him—if the monsters don’t tear him apart first.

The black dragon that rose from the depths of the South Sea unleashed an apocalyptic tsunami... Flame demons destroyed city after city made of steel and concrete, calmly departing from the center of nuclear explosions... Alien gods attempted to rule the entire galaxy...This is a future world where human technology is highly advanced.It is also an era that sparked a frenzy of Life Evolution in the Martial Path.Li Yuan, a Martial Path student on the verge of taking his college entrance exams, struggled to advance in this world while harboring the peculiar Divine Palace capable of envisioning the galaxy.Years later.“My current flying speed is 122,682 meters per second, and my power burst is...” Li Yuan flew at extreme speeds through the atmosphere about 180 kilometers above the surface of Blue Star, his cold eyes fixed on the massive creature at the dark void's edge, resembling the mythological dragon: “You, must be the strongest among all the invading Demigod life forms.”“It's just unfortunate that I can now be called... Martial God!”

Eren Idril died as an old, decrepit, and piss-poor adventurer by the maws of a D-Rank monster. He had a lot of unfulfilled dreams and desires that couldn't see the light of the day after the light in his own eyes died down.

But fortunately for him and unfortunately for the world, that wasn't his end. Eren was somehow dived back in time when he was a mere teen, attending Lionheart Academy for adventurers.

When life gives him a second chance, Eren decides to exploit it to its fullest. Experience his vile deeds as he partakes in them without feeling the slightest bit of hesitation.

Swordmaster Karyl MacGovern.

He returned to the past, wanting to rewrite the future he was unable to change with his sword alone. And this time, he would acquire the power that once eluded him—magic.

This time, he would master both sword and magic, and stand on the peak.
