In the 1970s, human physics made significant progress. Human beings no longer explored space, but instead explored the interior of the earth.

The level of technology inside the ruins was far beyond what humans knew. Even the theory did not apply here. As we went deeper and deeper, it became more and more confirmed that the earth was far more than the surface.
