Death was supposed to be the end.

Instead, it became a new beginning.

After dying in his world, a young medical graduate awakens in the body of Ethan Hale, a fifteen-year-old boy in a brutal world of monsters, nobles, and power. When his village is destroyed and his father killed, Ethan is taken by slave traders and sold in a market where human lives have a price.

Purchased by a noblewoman who sees potential in him, Ethan is forced to adapt to a world where the weak are devoured and survival is never guaranteed.

In a land shaped by a mysterious force known as Origin Essence, Ethan must rely on his knowledge, his mind, and his will to survive a world that is cold, cruel, and hollow.

Because in The Hollow World…

only the strong survive.
