Adventure Through the Emerald Kingdom

Sproutfield City was along the coastline and used water from the ocean to irrigate their fields after removing the salt from it to sell separately.

The entire city was covered in knee-deep water with boats and gondolas floating on top of them at every moment. The houses were built onto the ground, steadied by metal rods that dug deep into the earth. 

They lifted the houses above the water.

The mortals were the ones that used the boats while the cultivators simply flew. Although, they still used a boat from time to time.

Alex sat on a gondola in the center along with the other three while a young guide steered their boat through the water.

The water fields had plants growing throughout most of them, with many only having only sprouted just recently. He could tell where the name of the city came from.
