Heavenly Wind Tribulation, Anomaly

Ordinarily, for a peak Nascent Soul cultivator to summon the Spirit Transformation lightning tribulation, they had to break through two barriers.

Those were the soul and mana.

There was no need to say much about the soul—it referred to a True Spirit Realm soul at the Spirit Transformation level.

On one hand, the cultivator had to find their true self within their soul and mind.

On the other hand, the strength of their soul itself had to surpass the peak Nascent Soul level.

Neither of these aspects could be lacking. Only by combining the two could one attain a True Spirit Realm soul and gain the preliminary ability to mobilize the heaven and earth's primordial energy.

As for mana, one had to advance from Mana with Spirit into the Spirit Within Dharma Realm.

Specifically, this was divided into two stages.

The first stage was breaking through the bottleneck.

To Fang Xiao, this was practically a mere formality.

Although his capacity was outrageously vast, the intensity of his mana was even more terrifying.

In particular, the cultivation of the Nine Revolutions Primordial Heaven Art touched upon nearly every aspect of Fang Xiao. It likewise had the effect of weakening bottlenecks.

Thus, in but an instant, he shattered the bottleneck.

The second stage was the qualitative transformation of mana triggered by the shattered bottleneck, thereby officially entering the Spirit Within Dharma Realm.

And as the bottleneck shattered, the heavenly tribulation would arrive as well.

If both mana and soul had successfully broken through, then borrowing the power of heaven and earth's primordial energy, passing the lightning tribulation would not be difficult.

But if either was lacking, or even if neither could be completed, then whether it was heaven and earth's primordial energy or the Spirit Transformation lightning tribulation, both would be fatal
