Under the physical law of gravity, one would expect to fall straight down if one loses their footing.

Just as I began to plummet into the abyss, I was unexpectedly pushed into a weightless state by a force emanating from the unfathomable depths below, causing me to float and sink in mid-air.
163Please respect copyright.ＰＥＮＡＮＡJmBu2fCCxq
Could this weightlessness be caused by the "stack effect"?
163Please respect copyright.ＰＥＮＡＮＡQtDndNEhpN
Astronauts typically train for weightlessness using facilities or devices such as buoyancy tanks, bed laboratories, and cable hangers. There are also mechanical simulation methods like air bearings, universal brackets, and tilting tables.

In addition to these, the most efficient method is to use an air push technology in a simulated weightlessness chamber resembling a chimney.

Could it be that this cavern was once a simulated weightlessness chamber?

Regardless, I only knew that if I was lucky, I should be able to return to my original location.

If not, I would be left a bloody mess...

I struggled to spread my limbs in an attempt to grab onto any protrusions in mid-air, relying on these supports to climb back up.

Suddenly, a gust of wind pushed me chaotically!
163Please respect copyright.ＰＥＮＡＮＡTUDDhRdXaZ
I was tumbling in mid-air!
163Please respect copyright.ＰＥＮＡＮＡddoaUmDREr
No matter how hard I tried to maintain my balance, I had completely lost control of my direction!
163Please respect copyright.ＰＥＮＡＮＡzltXobZDvA
Was I flying toward heaven? Or plunging into hell?
163Please respect copyright.ＰＥＮＡＮＡeGXBa2lUsY
I had no idea how long I had been tumbling.

I seemed to see a "halo" hanging at the end of this dark tunnel.
163Please respect copyright.ＰＥＮＡＮＡeMc88DcJFn
Quickly! I burst through that halo!
163Please respect copyright.ＰＥＮＡＮＡntt7F81Uc9
Then… in the haze, I saw a series of numbers counting down…
