Dragon King
After a long battle between the two Dragon Kings, the Dragon King of the East Sea retreated deep into the oceans. The Dragon King of the West Sea roared and leaped in joy. As he did so, Wang Janggun shot down the Dragon King of the West Sea with his bow and arrow. The Dragon King of the West Sea's scale was so hard it could not be destroyed even by lightning; however, Wang Janggun pierced the scale with nothing but his strength.
