Yes, a ninth-tier defensive formation contained certain laws of heaven and earth. It stood closest to the Heavenly Dao and was the most powerful formation in this world. Never mind cultivation levels like those of Dao Lord Long Kuo and Dao Lord Bei Kui-even if dozens of Tribulation Transcendence Stage cultivators attacked it together, they might not be able to shake it in the slightest.
Neither ten thousand years ago nor ten thousand years later had there ever been a cultivator capable of successfully inscribing such a formation.
There was even a saying circulating in the world: ninth-tier formations were actually equivalent to immortal-grade formations, and simply could not be inscribed by cultivators of their realm.
Then someone asked: if no one could truly inscribe them, how could the formation patterns circulating in the world be explained?
Someone answered that ninth-tier formation patterns circulated in the world because an ascended predecessor had once returned to the Azure Realm, bringing formations from the Immortal Realm with them. That was what had led everyone to mistakenly believe ninth-tier formations truly existed.
Of course, that was not the only rumor about ninth-tier formations. Others said there had indeed been ninth-tier Formation Arts Artists ten thousand years ago, but the changes in the world had submerged them in the long river of time.
After all, ninth-tier formations were far too remote for ordinary cultivators. With that distance came fewer people who paid attention to them, and their disappearance became inevitable.
In short, opinions abounded. As for what the truth actually was, no one bothered to investigate anymore.
Just as they had speculated, who would obsess over something they could never reach in their entire lifetime?
Even Formation Arts Artists capable of reaching the seventh tier were exceedingly rare in this world. The ninth tier?
