Thousands of years ago, land civilization collapsed, and humans sank into the deep blue sea and evolved into a sea-dwelling race that lives in water all their lives.
The sea became the only home for mankind, and the dry land was designated as an eternal forbidden land by history books. Generations of undersea people have lived in ocean currents, grown up in blue waves, breathed sea water, traveled on the seabed, and built cities among coral sea rocks. Everyone has been taught since childhood: land is a barren and dead land, and you will die if you step on it. A world without water never belongs to humans.
Young Lin Yan grew up in a stable and peaceful floating city on the shallow sea. He lived a regular underwater life, but he was born with curiosity that went against the world. He does not believe in the taboo commandments passed down from generation to generation, and is obsessed with the "terrestrial legends" that have been sealed away by the people.
With repeated ocean explorations and deep-sea explorations, ancient ruins have appeared one by one. The mottled murals and broken historical materials have slowly revealed the cruel truth that has been buried for thousands of years.
Human beings were never born to belong to the sea.
The deep sea is the salvation after despair, and the land is the original home of civilization.
When ten thousand years of faith suddenly collapses, and when the understanding of the entire underwater civilization is completely overturned, Lin Yan will go against the current with the truth, cross the endless waves, and lead the ethnic group to find the way back that has been lost for thousands of years.
