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.

Could this weightlessness be caused by the "stack effect"?

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.
409Please respect copyright.ＰＥＮＡＮＡHTdDQBtcb6
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.
409Please respect copyright.ＰＥＮＡＮＡdWRcXXHgV6
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!
409Please respect copyright.ＰＥＮＡＮＡVtM2fTdXGV
I was tumbling in mid-air!
409Please respect copyright.ＰＥＮＡＮＡUC0IOcxFkb
No matter how hard I tried to maintain my balance, I had completely lost control of my direction!
409Please respect copyright.ＰＥＮＡＮＡ75bAgzM7w8
Was I flying toward heaven? Or plunging into hell?
409Please respect copyright.ＰＥＮＡＮＡg4flxszq6p
I had no idea how long I had been tumbling.

I seemed to see a "halo" hanging at the end of this dark tunnel.
409Please respect copyright.ＰＥＮＡＮＡ17xu2E995W
Quickly! I burst through that halo!
409Please respect copyright.ＰＥＮＡＮＡpAzsVvVfRX
Then… in the haze, I saw a series of numbers counting down…
