In this chapter, we learn that the ghost of the ship that attacked the Japanese pirates is named "caoding," which means "the ghost of a ship." In other words, the ghost was the one who defeated the Japanese invaders on the sea. This is the same ghost that killed the ship's captain in the opening scene of the previous chapter. The ghost of this ship has been haunting the mountain where the Tong City is located for the past five hundred years. The Tong city has been under the control of the Ghost since then. Now, the Ghost is trying to break free from the prison.
