Humans are just moss living on control panels
Within the ozone layer is human water.
We are born here, breathe here, and regard it as the boundary of life. When the diver looks up, the water surface is a sparkling barrier, isolating the suffocating upper realm. We have never thought that we are also "divers" of another existence - in the eyes of the more ancient masters, this thin gas wrapping the earth is just an insignificant layer of condensate on the surface of the control room console.
Xuan type civilization was born in the furnace of the earth's core.
Their city is rooted in the tumbling silicate mantle, and its neural network runs through the planet's magnetic field. With Gaia-Prime as its cold heart, it drives the energy cycle of the entire solar system. For them, penetrating the thick lithosphere to reach the surface is like diving naked into a 10,000-meter ocean trench. It's not anaerobic, but suffocation - the thin oxygen on the surface, the weak gravity, and the dazzling sunlight are all highly toxic. The "water" that humans rely on for survival is a sea of acid that is strong enough to corrode scales for xanthellae.
The solar system is a sophisticated power matrix.
The sun is the engine, the planets are the conductive orbits, and the earth is the core control room of the matrix. Humans are nothing more than parasitic organisms that accidentally breed in the gaps in the control room panels - in the vast species classification database of the xyloid civilization, we are labeled as Homo sapiens parasiticus (Homo sapiens parasiticus). To the control room owner, it's just biofouling spreading across the panels that needs to be removed.
Does the world outside the solar system really exist, or is it a high-dimensional projection?
