Boom!
The rock face seemed to be shaken by some invisible force, the rocks loosened and cracked.
Large chunks of stone fell from the rock face, raising dust.
Yang Tianxuan and the others looked on curiously.
The original rock face disappeared, a wide tunnel appeared before their eyes.
The tunnel was deep, a faint breeze blew from within, carrying slight chills.
Gazing into the depths of the tunnel, a faint green light emanated.
"Put away the mining robots, let's go inside and take a look," Yang Tianxuan spoke in a deep voice at this moment.
The members of the Doomsday Technology Guild heard this, and swiftly stored the mining robots in their space bags, then followed Yang Tianxuan curiously into the tunnel.
