Shikijiro Nijuichi gripped the ancient compass in one hand, while three other arms lifted the pickaxe, carefully distinguishing their position in the deep, long tunnel.
Once he pinpointed the indicated direction, he swung the pickaxe forcefully once again.
Clang! Clang!
The solid rock, seamless and hard, was effortlessly chiseled open.
This continued for nearly half an hour.
With his rich experience in mining, Shikijiro Niju sensed something slightly off with the feel of the pickaxe in his hands.
Clang!
Another swing of the pickaxe came down.
Several pieces of rock crumbled into the rock wall.
A narrow opening appeared on the rock wall in front of Shikijiro Niju.
And the [Mining Needle]'s pointer was right directed at this spot.
After intuitively assessing that the structure of the mine wouldn't collapse, Shikijiro Niju attempted to break the opening wider.
A few more strokes, and he was met with an incredibly old ancient scent as it wafted over.
