Return to Sea

In the 900th year of the sea calendar, 9 centuries have passed since humans set foot in the ocean. Due to the sharp increase in temperature, the blue color of the earth's surface is gradually eroding the entire sphere. Humanity was forced to re-enter the ocean. Just like millions of years ago, human ancestors struggled out of the ocean and searched for a living space in the unknown. In human history, this large-scale migration activity is called—— Return to sea.
