Soon-shin arrives in a small pottery town of Gonyang. Namgoong Du is an old potter and a martial arts master. Soon-shin's persistent pleading moves Namgoong Du to take him in as his disciple. Soon-shin's first lesson is to find clay suitable for pottery. After days trying and failing, Soon-shin seeks help of a local boy named Jang-pyung to find suitable clay. Soon-shin confesses to having sought someone else's help, but Namgoong tells him that there is no shame in asking for help in order to make a right decision. Days pass, but there are no martial arts lessons. Namgoong tells Soon-shin that he will teach him martial arts once he opens his mind's eye. Meanwhile, Yi Hwang tells Sung-ryong that learning is not a true learning without action and tells him to go to Prince Ha-sung in Sajik.
