Reaching Mortal Transcendence through a core that had all the characteristics of a normal Crystal Core, but was in fact an auxiliary one, was a theory, and though Wu Long figured it had a high chance of being true, there was still a possibility that it would fail.
After all, he never heard of anyone having more than one core.
But the transformations that were happening to his body were proof he has successfully advanced, as the constant nourishment pouring from his Dantian up into his Root of Longevity became far more stable and powerful, not only greatly extending his natural lifespan, but also alleviating the final bits of his Mortal Needs, as long as he supplied enough Spiritual Qi.
He could also feel Spiritual Qi saturate his flesh in a qualitatively different way.
