Zhao Hai was studying the ghost-faced ship in the medium. While he was studying the ship, he had to admit that the design of the ship was really good. The entire ship was made of the bones of demonic beasts. Each bone was refined with all the energy of the demonic beast. It could be said that after the refining was completed, the bone would be as powerful as the demonic beast at its peak.
After piecing the bones of these demon beasts together, he would use a type of yin energy thread to connect these bones together and make these bones a whole. This would turn into the ghost Face ship.
