Looking at the direction indicated by the compass, it clearly pointed to the source of the vibrations.
Out of caution, Li Fan donned a Taoist robe, performed an invisibility charm, and secretly made his way over to investigate.
Then he saw it.
It was an open-pit mine, the typical spiral-shaped diamond drill hole, at least a thousand zhang in diameter, reaching five hundred zhang deep into the earth's veins. It was clearly man-made, with smooth and even cut marks visible on the pit walls. Such a large-scale transformation of the surface had started to affect the planet's internal magnetic field, creating a powerful vortex with the atmospheric pressure above the ground. If birds or even small flying machines passed by, they could be sucked into the cavern by this whirlwind.
With just a guess, Li Fan knew what was going on.
