Qianting Zongdongyuan 3: Caihong Baozang

Synopsis

300 years ago, coastal residents could not bear the oppression and raid of foreign colonial invaders and formed pirates to fight against colonists. The pirates snatched the treasures of the colonists and buried them in a mysterious sea. Legend has it that the mountain of treasures shines and turns into a beautiful rainbow. From then on, the pirates and their treasures are known as rainbows. Bobo, a beaver who claims to be a descendant of the rainbow pirate (voiced by Xie Yuanzhen), weaves the legend into a story and tells the inhabitants of the sea. As a result, it attracts the seahorse family who cannot find treasure and the vicious and mysterious one-eyed shark (voiced by Tan Mantang). In a critical moment, Bobo was rescued by the small submarine Ali (voiced by Fan Churong). They brought the small submarine Beibei (voiced by Hong Haitian) and the Seahorse family on a journey to find the treasure of the rainbow. 　　 At the end of the vast sea, what will be waiting for these adventurers?(translated from douban)
