The Hero Uncle Has Returned

Heo Hun, who had fallen into an unconscious state and crossed into the other world of Midland, underwent four reincarnations and lived as a hero there. After defeating the fourth demon king and returning to Earth, he finds that Midland has become connected to Earth, allowing monsters to invade.

Because of that, his parents have died, and all that remains are his older sister and her husband, his two nephews, and the debts caused by his unconscious condition. The returned hero Heo Hun decides to pay off the debts and restore his family, together with that damn hero's sword.
