Core of the Earth

Intraterrestrial, the interior of the earth. This can also be said to be the world inside the earth. From the ground down, people on the earth may never have imagined that the inside of the earth should be full of magma. Such a scene, a giant artificial sun suspended in the sky, artificial weather here, and natural scenery that is the same as on the earth, but the land area is only half that of the earth. Magic and technology coexist here. The true technological level of the earth lies within the earth. The ground is just an ecological box in which the earth observes itself.
