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.
236Please respect copyright.PENANAv8tFkvZX9G
Could this weightlessness be caused by the "stack effect"?
236Please respect copyright.PENANAWo4gxboHMB
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.
236Please respect copyright.PENANA55NfJ2Gx2K
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.
236Please respect copyright.PENANAJreASKg2BH
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.
236Please respect copyright.PENANANccV2Q6un5
Suddenly, a gust of wind pushed me chaotically!
236Please respect copyright.PENANAzxZ1M5w9bf
I was tumbling in mid-air!
236Please respect copyright.PENANAl8C9lQSJyh
No matter how hard I tried to maintain my balance, I had completely lost control of my direction!
236Please respect copyright.PENANAFIBHzeInGA
Was I flying toward heaven? Or plunging into hell?
236Please respect copyright.PENANAsINzwuP6JO
I had no idea how long I had been tumbling.

I seemed to see a "halo" hanging at the end of this dark tunnel.
236Please respect copyright.PENANAdrLvrKKWm0
Quickly! I burst through that halo!
236Please respect copyright.PENANApwNm5pQd7Q
Then… in the haze, I saw a series of numbers counting down…
