After a plane crash, flight attendant Xia Yao and teenage girl Li Wei drift to a mysterious island. This island is formed by the canopy of the Fusang Tree from the "Classic of Mountains and Seas," which sank due to a seal, hence the name "Fusang" Island. The island is covered with gigantic exotic flowers and colossal monsters. For tens of thousands of years, the outside world has been unable to discover it, and the creatures on it cannot leave. The two girls are regarded as the Nine Heavens Mystic Maidens by the Ear Rat tribe on the island. The prophet tells them that to leave Fusang Island, they must ascend Tianwei Peak and obtain the Golden Crown to break the seal. The descendants of the island's Four Great Fierce Beasts covet the divine power of the Golden Crown and seek to capture the two girls.

To protect Fusang Island and save the world, Xia Yao and Li Wei unite the Ear Rat tribe and the descendants of the Four Great Fierce Beasts, engaging in a desperate battle against the evil dragon at Tianwei Peak...
