Three-Layer Ocean, Horrible Moon

Among the eight planets in the solar system, Jupiter has the most satellites with 79 of them discovered so far.

Among so many satellites, Ganymede was the most special.

What was so special about it?

It was not only the largest—larger than Mercury, one of the eight planets—but it also had oceans and oxygen.

Stepping on the surface of Ganymede is no different from Europa. Its surface temperature is about minus 160°C.

The gray-white surface is full of various stones, ice cubes, and gray dust, looking very dirty.

However, it stunned Ling Jiu when he crossed the surface of the land and came to the ocean below.

Gleaming stars dotted the dark ocean. They were so densely intertwined that together they looked as if the Milky Way, deep and vast, bright and mysterious.

"Is this really an underground ocean?"
