Enemy in the Narrow Pathway 2

After Jian Gang left, Xueming stood up and brushed off the dust before walking deep into the destination. He quietly disappeared from the spot where everyone was digging. The other miners were not suspicious as they thought that Xueming was hurt and scared of Jian Gang, so he fled to another place.

...The Silver Vein

Xueming followed the traces of the mineral veins as Zi Hui suggested. Until finally, he reached a dead end. Xueming used his hand to feel and follow the texture of the stone for a moment. He then took out some sort of liquid and poured it onto the stone wall. The black liquid rushed into the silver vein before instantly sinking into the wall.

…It’s definitely inside. Zi Hui said that this liquid was extremely sensitive to the Qi Core. The closer it got, the faster it got as well, as it was used to find the center of the mine to determine mining directions.
