Lin Yuan, once known as a genius waterbender, had his dreams shattered after awakening the most useless ornamental fish spirit pet. He became an ordinary model enthusiast, making a living by making ship models. When he was frustrated, he accidentally activated the hidden properties of the ancestral fish tank, turning it into a "cave heaven" that could be carried around - an endless "ancient sea of primordination". This ancient sea can not only accelerate the growth and evolution of spiritual pets, but it is also home to countless ancient ocean beasts that have long been extinct in the outside world.
Lin Yuan started by cultivating a "fluorescent clownfish" in a fish tank that could defeat the betta fish of the old man in the neighborhood. Through continuous exploration of the ancient sea of Taichu, he captured, cultivated, and evolved an invincible fleet composed of legendary beasts such as Leviathan, Kraken, and Mosasaurus. He used his identity as a "model enthusiast" as a cover, starting from anonymous online competitions, pretending to be a pig and eating a tiger, and entered the professional league, shocking the world. When everyone thought he was just lucky, he rode a world-destroying sea monster and announced to everyone at the finish line of the World Series: I have the final say in this ocean!
