This is a map of an abandoned mine, and the so-called "Easter egg" is a special mineral called "Chongming".
This mineral is similar to Ximolai Ore in a way, but compared to the now obscure Ximolai Ore, Chongming Ore has already entered many fields and become the core mineral material for the energy engines of many mechas!
Although this mine has been abandoned, there is still a significant amount of Chongming Ore inside. This mineral itself is also slightly radioactive, but this radiation is not harmful to the human body. However, if stimulated by special spiritual waves, the mineral will emit a field that disrupts the magnetic field, reducing the combat effectiveness of many moderately configured mechas by at least 30-50% under such a magnetic field!
