Dreaming of Mountains and Seas

The merfolk crown prince, Yi Lan, underwent the ritual to have his tail and gills removed. His body weak with exhaustion, he sat in a sea palanquin on his way to the imperial capital on land, Tide-Song City, to marry for an alliance. Near the shore, a sudden storm swept the prince and his palanquin back into the sea. Having just lost his tail and gills, he drowned in the waters where he had once breathed freely.

The sea and land erupted in uproar. The merfolk factions accused the dynasty of contempt and humiliation, and resentment spread everywhere. War between sea and land seemed imminent. After months of silence, the clan chief made a decision that stunned everyone: he would send the young prince Yi Shan to marry for an alliance in his brother's place.

Yi Shan demanded, "My brother's death was suspicious. Are you going to make your son follow in his footsteps?" His protests came to nothing, and he still set out as scheduled. But no one knew that halfway through the journey, the soul in the young prince's body had been replaced by one from another world: Meng Yishan, a modern vocal coach.

Temple priests guard the border, former court officials and secret agents scheme across the political landscape, a stubborn patriarchal faction watches like a tiger, and the powers of the deep sea wait for their chance... With a modern soul taking up the mantle of the prince of the deep, can he avoid the fate that befell the crown prince and marry the empress of a sea kingdom from another world?

In truth, this is only the simplest of many questions.
