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.
121Please respect copyright.PENANAdPfp2ZlXsT
Could this weightlessness be caused by the "stack effect"?
121Please respect copyright.PENANA6Qpl3XoAQy
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.
121Please respect copyright.PENANAqRDEnr06Li
Could it be that this cavern was once a simulated weightlessness chamber?
121Please respect copyright.PENANA2g7h6maJEk
Regardless, I only knew that if I was lucky, I should be able to return to my original location.
121Please respect copyright.PENANAEPQdSp58f2
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.
121Please respect copyright.PENANA0D6wjhQZkz
Suddenly, a gust of wind pushed me chaotically!
121Please respect copyright.PENANAnGiyvnS1li
I was tumbling in mid-air!
121Please respect copyright.PENANAYIzbsEh8DV
No matter how hard I tried to maintain my balance, I had completely lost control of my direction!
121Please respect copyright.PENANARTj69PIiz3
Was I flying toward heaven? Or plunging into hell?
121Please respect copyright.PENANAxyIImUREHB
I had no idea how long I had been tumbling.

I seemed to see a "halo" hanging at the end of this dark tunnel.
121Please respect copyright.PENANAFdTze77Kum
Quickly! I burst through that halo!
121Please respect copyright.PENANAByl7Yop05P
Then… in the haze, I saw a series of numbers counting down…
