The Purple Firmament Sect's foremost Sect's Treasure was the Profound Purple Sword. In addition, it possessed another Sect's secret art—the Purple Flame Lightning Art.
The Purple Flame Lightning Art was an Immortal Realm secret art and the Purple Firmament Sect's closely guarded secret. To cultivate this divine art, one had to be a disciple nurtured by the Purple Firmament Sect, and one's cultivation had to have advanced to the Spirit Severing realm.
Even after meeting these two conditions, one still had to swear a blood oath during cultivation and have the sect's elders place a seal within one's sea of consciousness.
This art was of tremendous importance to the Purple Firmament Sect. It absolutely could not be cultivated by cultivators outside the sect.
Moreover, not every Spirit Severing stage cultivator who advanced their cultivation could successfully cultivate the Purple Flame Lightning Art. This strange-fire art was the most terrifying divine ability in the Cultivation World. Naturally, cultivating it was exceedingly difficult. One wrong step, and the result would be the burning away of one's physical body and the extinction of one's soul.
Although the Purple Firmament Sect protected everyone who cultivated it, cultivating this strange-fire art was ultimately far too dangerous. Since the Purple Firmament Sect was founded, more than a hundred cultivators had fallen while cultivating the Purple Flame Lightning Art.
Over a hundred cultivators might not sound like many across the long river of the Purple Firmament Sect's history, but this number came after passing a test the Purple Firmament Sect had specially established for cultivating this divine ability.
And since the Purple Firmament Sect's founding, only two or three hundred people had managed to pass that test.
Half of those cultivators had perished while cultivating the Purple Flame Lightning Art. This casualty rate was undeniably high.
