The Undefeatable Swordsman

Sung Woo-mun is a weak, sickly boy whose mental abilities deteriorate after he receives a painting from a sage. Growing up as the “village idiot,” he is pitied even by his own parents. When Woo-mun turns twenty, an epiphany marks a change in his life, and an undefeatable martial arts power begins to awaken within the painting. As his destiny shifts, he faces questions about what the painting means and what strange world lies ahead.
