I am the god of this land.

A grandfather's archaeological treasure and a mysterious fish tank, sealed away by time, completely rewrite the protagonist's life. This fish tank is no ordinary object, but a self-contained microcosm capable of housing countless creatures of Earth. The protagonist becomes the supreme ruler of this world, wielding the power of time and space, able to manipulate the flow of time and set the rules for all things. He gradually moves Earth's creatures into this space, allowing them to grow wildly, reproduce, and pass on their lineage. As an observer, he witnesses a new ecological evolution and the rise of civilization, personally creating a completely different history and endless opportunities for Earth.
