Xuan Yuan Jingxiu's words surprised Ning Wangshu.
He was surprised not only that the highest cultivation realm attainable in the secret realm Xuan Yuan Jingxiu had once lived in was only the peak of the Nascent Soul Stage.
He was even more surprised by the confidence Xuan Yuan Jingxiu's words revealed in the "foundations" of their lineage. They were confident that even without drawing on those "foundations" ahead of time...
Even if the All Heavens Seal completely collapsed in the future and the many secret realms truly emerged, they would still be able to cow those secret realms and keep their inhabitants from acting recklessly!
Ning Wangshu knew that the strongest cultivators in the Three Immortals Island Secret Realm and the Supreme Secret Realm, as well as the Zhongnan Secret Realm, had all reached the peak of the Body Integration Stage.
There were even cultivators at the peak of the Tribulation Transcendence Stage in the Shangqing Secret Realm.
However, because the immortal formation and Immortal Restriction blocked them, the cultivators there could not summon a Heavenly Tribulation. So those at the peak of the Tribulation Transcendence Stage had no choice but to stop there, unable to advance any further and reach the Mahayana Stage.
Once the All Heavens Seal disappeared and the Shangqing Secret Realm emerged, those at the peak of the Tribulation Transcendence Stage might well be able to summon a Heavenly Tribulation. If they survived it, there would be cultivators at the Mahayana Stage!
Ning Wangshu didn't know whether Xuan Yuan Jingxiu knew the circumstances in the other secret realms. But even if he didn't, the fact that he dared to say such things showed just how confident he was in his lineage's "foundations."
Those "foundations" were probably powerful enough to deal with cultivators at the very least
