Such a powerful ghost sprang up from the center of the Mass Grave, and yet, this occurred in a place with such a dense population and strong yang energy—the reasons for this warranted deep thought!
Generally speaking, Mass Graves are not suitable for the construction of residential housing, parks, or roads due to the large number of dead and the overwhelming yin energy.
Because such buildings are scarcely populated, they cannot suppress the intense yin energy, which often brings trouble to the inhabitants.
If it were an apartment building, at best, occupants might fall ill due to the imbalance of yin and yang energies; at worst, they may very well die because of it!
If a road were constructed, it might be okay during the day; however, at night, the powerful yin energy could cause various illusions, leading drivers who are deceived by these phantoms to inevitably have accidents.
The same principle applies to other cases, which need not be repeated here.
