"Undying Power has been depleted by one-twentieth?"
As Ye Chen flew backward, the injuries within his body healed instantly. Though Life and Death Realm Kings possessed Undying Bodies and need not fear even being smashed to pieces, that was merely a superficial understanding. Battles between powerful warriors contained martial will. Once martial will invaded the body, an Undying Body alone was utterly useless; one needed True Essence working in tandem with one's own will to suppress or even expel it. Undying Power, however, was a mysterious force, far more than mere energy. The martial will Green Tang Emperor had struck into Ye Chen's body was instantly erased, though about one-tenth of his Undying Power had also been consumed.
"I underestimated you. So your Spirit Body has reached the seventh rank."
Green Tang Emperor saw at once that Ye Chen's injuries had recovered. A Sixth-Rank Spirit Body could not have achieved such an effect; only a seventh-rank Spirit Body fit the bill.
The higher a Spirit Body rose, the more difficult it became to improve. Under normal circumstances, Eighth Heaven emperors possessed seventh-rank Spirit Bodies. The more formidable among them, such as top-tier emperors or quasi-Supremes, could reach the eighth rank. Even among Nine Heavens of the Life and Death Realm Supremes, not everyone possessed a Ninth-Order Spirit Physique. Most still had eighth-rank Spirit Bodies, though they would certainly have reached the late eighth rank or even the peak of the eighth rank. Only upper-tier Supremes or Super Supremes possessed Ninth-Order Spirit Physiques.
That was excluding Body Refinement Kings.
Many Body Refinement Kings possessed Ninth-Order Spirit Physiques while still at the Eighth Heaven. As for Ninth Heaven Body Refinement Kings, not only had their Spirit Bodies reached the late ninth rank, every one of them had cultivated formidable body-refinement Martial Arts.
