I, the Owner of the Mysterious Island

The arrival of a faded letter leads the unemployed Su Yan to the island that has never been marked on the map. The letter said that he was the new owner of the island. It wasn't until he set foot on this island filled with thick fog that he discovered that the so-called island owner was just the caretaker of this asylum - the conch that could create illusions, the mermaid that could cry out pearls, and the shadow that fed on fear. It was the island owner's job to understand their habits, take them in, and use the resources they generated to create weapons.
