Xu Yuan wanted to see how fast he would absorb the divine energy if he released his Martial Spirit and Martial Soul, definitely not what others could imagine.
It could be said that perhaps only Xu Yuan possessed the first Martial Soul in the God Realm or even in the Universe. Martial Spirits did not limit a cultivator's potential. Still, with a low-rank Martial Spirit, the absorption of Divine Energy would also be severely limited, so reaching higher stages would take longer.
That was why even a cultivator possessing a Martial Spirit of the Zhou level had to spend millions or even billions of years to break through to the True God stage.
The knowledge of the mysteries of the universe that resided within his head allowed all three Martial Aspects to be divided into different types of energy absorption.
