This is an "ocean" composed of clouds and mist. Dust permeates this environment of weak gravity, neither falling nor drifting away.
This "sea" formed by dust and gases is not deep, merely tens of thousands of feet. However, it is too vast—vast enough for the entire Shenzhou Hou Tu to roll about on it. From the surface of the sea, the eyesight of ordinary life beings cannot even reach the edge of this great ocean. There is no horizon here, the end of the "ocean" is just starlight.
This is Jupiter—known to the Dragon Clan as "Tianhe".
Sunlight slants over the "sea surface", revealing shadowy "wave crests". The distance to the Sun here is originally farther than Shenzhou is from the Sun. Besides, at this distance, the luminous atmosphere of the Sun is barely visible to the naked eye, making the Sun appear more like a shooting star, much brighter than a first-magnitude star.
Still, this faint sunlight can support life beings' activities.
Within "Tianhe", dragons swim leisurely.
