Ying Xiaoqi is an ordinary fish spirit living in a water house isolated from the world. His favorite daily hobbies are blowing bubbles and escaping to practice. However, the peace was broken by the "Xunlongting", a human organization equipped with high-tech weapons. The tribesmen were taken captive and their homes were destroyed. Forced to embark on an adventure, he discovers that he is the legendary key bloodline with the potential to "transform into a dragon".
On the way to escape, he got acquainted with a series of strange partners such as Ayan, a human technology geek who is obsessed with black history but has always discovered a big fryer, Cangya, a wolf demon with explosive combat power but even worse temper, and a mysterious and wise siren guide. They drive a dilapidated modified ship, shuttle between ancient ruins and future technology bases, explore the truth behind the disappearance of the dragon clan, and fight against the "Dragon Gate Project" of the leader of the Dragon Court, Morpheus, to resurrect the ancient evil.
