Andre continued, "The more important feature about Flame Rocks is it increases the concentration of energy. This is a natural energy fragment. Moreover, the more the energy is active, the higher the absorption efficiency. Therefore, Fire Dragon City is constantly increasing the mining of Flame Rocks, which brings about a series of problems.
After a long period of mining, the difficulty of mining Flame Rocks became greater, so the time needed to mine also became longer. Although Lava World is not like our training ground, where it was impossible to stay for a few hours, it would still be uncomfortable to stay inside for a long time.
