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.
235Please respect copyright.PENANAtxmu3qC6W5
Could this weightlessness be caused by the "stack effect"?
235Please respect copyright.PENANAjwaA7UHDvf
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.
235Please respect copyright.PENANAOWxWeQS5K9
Could it be that this cavern was once a simulated weightlessness chamber?
235Please respect copyright.PENANAQOKhm0nmKY
Regardless, I only knew that if I was lucky, I should be able to return to my original location.
235Please respect copyright.PENANAk7qX9XR4Ba
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.
235Please respect copyright.PENANAgK9IJYhX78
Suddenly, a gust of wind pushed me chaotically!
235Please respect copyright.PENANA3WcZTmRY5I
I was tumbling in mid-air!
235Please respect copyright.PENANAz781u3r2sJ
No matter how hard I tried to maintain my balance, I had completely lost control of my direction!
235Please respect copyright.PENANAEKW25mWy8e
Was I flying toward heaven? Or plunging into hell?
235Please respect copyright.PENANARMITbZN4cj
I had no idea how long I had been tumbling.

I seemed to see a "halo" hanging at the end of this dark tunnel.
235Please respect copyright.PENANAYk83JPKBuN
Quickly! I burst through that halo!
235Please respect copyright.PENANAs3c1O8LPgs
Then… in the haze, I saw a series of numbers counting down…
