Desert Island King: Starting from Picking up the Facially Paralyzed Mermaid

My name is Li De, I am a fishing blogger, but I accidentally broke into a fog and traveled to a fantasy world of sailing similar to the 17th century. Seven days later, the food and fresh water were completely exhausted. Just as I was writing my last words and waiting for death, a huge sailboat came from afar. Unexpectedly, these people were human traffickers. I was sold to a small sea town and became a slave. At a critical moment, the mermaid army raided the town and took me to the deep sea, saying that the queen wanted to summon me. I was secretly happy, and wondered if I had traveled to an unorthodox world? Being a Neptune seems to be a good idea, right? However, when I saw the so-called mermaid queen with my own eyes... Hiss~ There is something wrong with this place... When I woke up again, I drifted to a desert island. There was a silver-haired mermaid sitting on the rock, her face expressionless and silent. [King Panel is activated] [Territory: The lost country that has been submerged by the ocean] [Industry: Nothing] Population: 1 [Information: In seven days, a group of exiles will pass by your territory. It is extremely dangerous, please prepare as soon as possible] It turns out that I was supposed to be the chosen king of an ancient kingdom, but I was unexpectedly thousands of years late? Now that the kingdom has been swallowed by the sea, I, the king, have become a mere commander. The small island in front of you is the last piece of land that the Kingdom has left above the sea. Fortunately, as long as I develop the island and expand my power, I can get generous rewards. In this way, I started from this desert island where monsters were rampant, and together with the paralyzed mermaid, I reclaimed fields, built towns, freed slaves, and built an ocean-going fleet. Cross the ocean step by step and eventually become the well-deserved king of the ocean.
