This miniature secret realm probably had nothing of value left.
After multiple iterations of digging, Duo Lai could only sigh with regret.
It could be the destructive effects of someone's excavation efforts, or perhaps because the secret realm was of small scale, its defensive strength of limited stability, it surprisingly started to hum with vibrations.
All around, the stone walls creaked and cracked open, with a faint view of drifting pale fog seen outside the crevices.
The grey mist was seeping in.
In the secret realm, strands of pitch-black fissures suddenly surfaced.
"Th- the secret realm is collapsing!"
The ceiling was also cracking apart, with dust rustling down followed by chunks of crushed rocks. This was a dire situation that even Duo Lai realised.
If it were a normal building collapse, no one present would be afraid; it would be nothing more than an inconvenience.
However, this was a collapse of a secret realm, something that would cause spatial turbulence.
