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.

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.

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!
202Please respect copyright.ＰＥＮＡＮＡ4p2ubuc5Pl
I was tumbling in mid-air!
202Please respect copyright.ＰＥＮＡＮＡ3QABjaLskY
No matter how hard I tried to maintain my balance, I had completely lost control of my direction!
202Please respect copyright.ＰＥＮＡＮＡvtvwXR0zER
Was I flying toward heaven? Or plunging into hell?
202Please respect copyright.ＰＥＮＡＮＡfFLldw29w7
I had no idea how long I had been tumbling.

I seemed to see a "halo" hanging at the end of this dark tunnel.
202Please respect copyright.ＰＥＮＡＮＡKfjIBO5E9P
Quickly! I burst through that halo!
202Please respect copyright.ＰＥＮＡＮＡhyF4opHxX9
Then… in the haze, I saw a series of numbers counting down…
