The Cloud Dream of the Nine - Zero

What if The Dream of Nine Clouds was just the title—and nothing more?
20-year-old Yang Soyu is an ordinary Korean man… until the day he’s summoned to another world. No status windows, no cheat skills—just guts, grit, and a world full of dragons.
With nothing but his will to survive, Soyu rises through the chaos and hunts down a dragon. But when he finally returns to Earth, nothing is quite the same.
This isn’t the world he left behind—
This is just the beginning of a modern action-fantasy with zero limits.
