Chapter 264: First Day of Underground Reconnaissance

An ordinary demon monarch would find it much more difficult to advance underground than me. They can only go up to 50 kilometers deep. Any further and the rocks are too hard for them; they will be too slow. To an ordinary demon monarch, going 50 kilometers deep underground is equivalent to traveling thousands of kilometers on the surface. Therefore, third Firmament demon monarchs are typically within 50 kilometers of the surface.

Fourth Firmament demon monarchs will usually be about 50 to 100 kilometers from the surface because of King White Treasure's constant reconnaissance. Meng Chuan nodded slightly. Earth Net also searches for demon monarch lairs. Although they can't be compared to King White Treasure, they can roughly figure out the unspoken rules of where demon monarch lairs are located.
