"King, Trap sent word. The reinforcement convoy has entered the canyon and linked up with the enemy there."
Alpha Wolf looked at Yu Yuan.
"I saw it too. Tell Trap to stay hidden. If things get dangerous, he should retreat rather than take risks!"
"I already warned him."
A map lay before Yu Yuan—or rather, a map of the mine tunnels.
The geologist Xu Ke and his student Es were studying it.
The mine map had come from Kuis.
He had only found it in the former mayor's home after occupying Dead Mine Town.
It contained detailed tunnel maps and mineral deposit information for the Dead Mine.
Of course, the information on this map dated back to before the Wasteland's arrival and was already outdated.
Xu Ke and Es were now updating and refining the map, filling in the newly discovered tunnels below.
Xu Ke leaned halfway across the table, carefully sketching from memory with a pencil on a sheet of blank paper attached to the map.
For a geologist like him, this work was not particularly difficult.
It was one of their fundamental skills.
After finishing the final stroke, Xu Ke let out a long breath. A faint smile appeared on his face as he pointed to the area he had just drawn and looked at Yu Yuan.
"Leader, this is the area where we found the rare earth deposit. It lies in the deepest part of the mine. Based on what I already know about the mine, this is very likely a rare 'mineral concentration zone,' characterized by multiple periods and stages of mineral formation.
"There are generally two models of mineral formation in these zones. One is vertical stacking, like floors in a building. The veins are divided into shallow, middle, deep, and extremely deep layers, with
