After Ten Millennia in Hell

Here's the improved synopsis, incorporating your requirements: After falling into Hell with nothing but his will to survive and predatory instincts, Oh Kangwoo devoured countless demons across a thousand hells, ultimately bending even the seven archdukes to his will. But after ten thousand agonizing years, he's finally had enough. "Why return? Your Highness already possesses everything in Hell!" they plead. "Everything, my foot! There's nothing but desolate land and hideous demons! I'm going back!" And so, Oh Kangwoo, the Demon King, returns to Earth, only to find his powers sealed and the world transformed into a sprawling MMORPG battlefield. Dimensional gates have appeared, and humanity survives by hunting monsters within them. "Players" level up and carve out a living in this new, dangerous reality. Now, to survive, Kangwoo must also level up, and quickly. But for this exiled Demon King, Earth, with its players and its gates, might just be worse than Hell itself!
