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.
146Please respect copyright.PENANADZRN3faPdX
Could this weightlessness be caused by the "stack effect"?
146Please respect copyright.PENANAtMZfHe2pEc
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.
146Please respect copyright.PENANAAFZMpkdWT3
Could it be that this cavern was once a simulated weightlessness chamber?
146Please respect copyright.PENANAqSKdcnZux4
Regardless, I only knew that if I was lucky, I should be able to return to my original location.
146Please respect copyright.PENANA1bfrHzMmWA
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.
146Please respect copyright.PENANAkrCmQufZyU
Suddenly, a gust of wind pushed me chaotically!
146Please respect copyright.PENANAzGvwieDOKf
I was tumbling in mid-air!
146Please respect copyright.PENANAMc9h8x87F4
No matter how hard I tried to maintain my balance, I had completely lost control of my direction!
146Please respect copyright.PENANARo9z9X9UDi
Was I flying toward heaven? Or plunging into hell?
146Please respect copyright.PENANAVoH7jJKdhg
I had no idea how long I had been tumbling.

I seemed to see a "halo" hanging at the end of this dark tunnel.
146Please respect copyright.PENANAyJxwLrYbqZ
Quickly! I burst through that halo!
146Please respect copyright.PENANAJF9Hg73Su1
Then… in the haze, I saw a series of numbers counting down…
