After half a day of assembling machinery, the prospecting equipment was finally set up and began detecting the crystal ore veins underground.
Yang Xiao realized that it was time to invite the geology expert, Old Nine, to observe the advanced technology of Witch Star.
When the prospecting equipment was activated, the ultrasonic waves penetrated one hundred meters into the ground, directly displaying the underground information in the form of images for everyone to see.
"Indeed advanced!"
Yang Xiao sighed internally; he remembered that on Earth, using sonic waves for prospecting could never reach a depth of one hundred meters, and it could not display images directly, only some professional parameters which required experts to analyze before yielding results.
The only regret about this prospecting equipment is that it has a very limited detection range, only about 5-6 meters nearby, and it needs to be constantly repositioned to collect information from an area.
