Ten million Netherworld Stones is not a small amount!
The Netherworld Sect, being a sect that can dominate a star system, has only about eight million Netherworld Stones in storage after plundering. Of course, some of the Netherworld Stones are used for cultivation or creating Corpse Masters.
It shows that Netherworld Stones are extremely precious and can only be obtained in some special Secret Realms, by killing Beasts, discovering Netherworld Stone veins, or from the tombs of some Great Powers from the Netherworld Era, where such rare resources can be found.
However, this is the Dark Demon Sea, where talents from various sects in major star domains and Princes of the Dynasties practice. With such a strong background, ten million Netherworld Stones, though many, is not an impossible number to produce. Only a few can come up with such a large amount of Netherworld Stones.
