Reborn in Naruto As Madara's Grandson - Chapter 6: Emergency

Joseph Knox, one of the most prolific and well-known serial killers on the planet.A person considered so demented and manic that even trying to reason with him was believed to be a waste of time. A man so far gone that he seemingly didn't deserve any pity even on his deathbed.So why? Why would a man like him receive a second chance? And why did the world around him seem so familiar?Disclaimer: AU when it comes to some parts of Madara's plan(I'll try to make it make sense at least), and aliens don't exist in this world

In a world where 70% of the population possesses powers managed by a LitRPG chip, Kang Ji-Hoon, a timid young man, joins the prestigious Apex Academy to save his sick mother. Ranked last at F with his seemingly useless ability to summon a dagger, he becomes the target of relentless bullying. Pushed to his limit, he unleashes the true power of his weapon, a dark and destructive force. As he transforms into a ruthless anti-hero, a cosmic threat emerges to assimilate humanity. Ji-Hoon then realizes his dark destiny: to save everyone, he must destroy everything.
