The crystal ball is a treasure corresponding to the Dragon Path on all Hailong ships sailing across the four seas.

Whenever someone appears on the Dragon Path, the crystal ball will naturally be triggered, drawing the attention of the Dragon Clan's higher-ups responsible for such matters.

Originally, this matter was not under the responsibility of Long Douhai and Long Sha.

Not long ago, Long Yanran had the two come over to personally oversee it because she had disclosed the secret of the Dragon Path to the Monarch of the Northwater Kingdom, Shui Meiren Liu Hongyan, which inevitably meant Luo Lie was coming.
