The 'land' beneath our feet is overwhelmingly enormous compared to an ordinary human's size, stretching over thirty thousand meters from the 'sea surface' to the ground, capable of covering the surface area of three master planes. Yet, it is merely a remnant of the Tree of Ten Thousand Realms floating on the Sun's surface.
Similar remnants can be found all over the Sun's surface, varying in size, most of which are carbonized, crystallized, and transformed into a new type of matter.
This substance has floated on the Sun's surface for who knows how many years, yet now, the calm surface of the Sun has begun to boil, temperatures suddenly surged, causing these land masses to start slowly sinking.
Under Ange's measurement, the land beneath our feet has sunken at least two meters. Relative to the thirty thousand meters height it floats above the surface, two meters is almost negligible. If Ange weren't equipped with the Libra that measures all things, he might not even have noticed.
