The Chaos Immortal Tribulation was an eight-nine heavenly tribulation.
Drawing on his own experience of undergoing Calamity, Gu Yuanqing explained everything carefully to Li Miaoxuan. The heavenly Calamity itself was secondary. Even leaving aside the fact that Li Miaoxuan far surpassed ordinary cultivators and possessed a supreme treasure, making her passage through the Calamity largely assured, protecting one person within the North Spring Grotto-Heaven was quite simple for Gu Yuanqing.
His main focus was explaining the various points she needed to watch for when breaking through from the Shattering Heaven Realm to the Immortal Realm.
Of course, all of this was merely for reference. Both the heavenly Calamity itself and the process of undergoing it differed from person to person.
Even those who practiced the same cultivation technique and established their Dao foundations upon the same Great Dao could experience vastly different changes.
That was all the more true of him and Li Miaoxuan.
Li Miaoxuan had also read through the Lingxu Sect's various texts on undergoing the Chaos Immortal Calamity. By comparing them with Gu Yuanqing's explanations, she gained a reasonably clear understanding of what lay ahead.
She then entered seclusion on North Spring Mountain to cultivate and bring herself into the best possible condition.
Gu Yuanqing also channeled the grotto-heaven's spiritual qi to aid her cultivation.
Another half month passed. Li Miaoxuan came to the summit and sat quietly for three days before the heavenly Calamity arrived.
Dense, black Calamity clouds enveloped Qian Yuan Island.
Everyone in the Qian Yuan Sect already knew someone would be undergoing Calamity, so they did not panic. They merely reined in their auras to prevent them from resonating with the Calamity qi and accidentally drawing them into it.
Gu Yuanqing stood a hundred zhang away from Li Miaoxuan, quietly keeping watch.
