Island for all: I built a home on the back of a giant turtle

The resources in the parallel world are exhausted. After everyone becomes an adult, they can enter a huge ocean world with endless resources and become the owner of an island.
As long as you can build and defend your own island, you can continue to discover the wealth and mysterious energy in the ocean and become a master.
At the age of 18, when others were scrambling to choose the large island first, Chu Chen, who had obtained the infinite evolution system, chose the Turtle Island, which was rarely chosen!
Start with a sea turtle that evolves into a legendary giant tortoise with a length of thousands of miles. There are mountains, rivers, farmland, and cities on the back of the sea turtle...
.
Evolve killer whales, evolve into ancient giant whales with a length of several hundred meters, which can swallow a boat in one bite, and successfully run across the ocean in groups. The fleet is terrified when they see it!
Evolve the seagull, evolve into a seagull fighting gun that is as fast as lightning and has skin like steel. Even fighter jets dare not take the lead!
Evolve a mermaid....One year later, you will get a **Little Mermaid...
