There was a great hope of succeeding in Tribulation Crossing, at least becoming a Loose Immortal.
One level higher, that was the extremely rare prodigious cultivator.
The thickness of mana was more than three times that of ordinary Mahayana Realm cultivators!
If not for the pure spiritual energy from the Spirit Vein Dragon, Su Xing should have been at this level.
This level of Mahayana Realm cultivators, at the first layer of the Mahayana Realm, had mana reserves comparable to cultivators at the sixth layer of the Mahayana Realm!
Once cultivated to the perfection of the Mahayana Realm, their mana reserves could rival that of a Transcendence Tribulation Stage cultivator who had passed the "Mana Pass" tribulation!
And this level was also known in Luo Tian Sect as a first-class Immortal Seed, with a great probability of becoming an immortal and walking the orthodox immortal path.
