A ten times blood exchange meant only one thing: he had cultivated the Nine Times Blood Exchange Technique and then broken through its limits to reach ten.
Su Mu had reached the Body Tempering Limit. Even without a Blood Strengthening Pill, it was possible for him to break the limits in the Blood Transformation Realm.
But that was only possible if he cultivated the Nine Times Blood Exchange Technique!
Each breakthrough could only increase the blood exchange efficiency by a single level. If he wasn't cultivating the Nine Times Blood Exchange Technique, it would be absolutely impossible for him to break through to a ten times blood exchange!
Ten times!
Ten times!
Those two words echoed in the minds of everyone in the hall. 'A ten times blood exchange...'
A nine times blood exchange already made one a dragon among men. What did a ten times blood exchange signify?
Even if it wasn't completely unprecedented, it was certainly enough to rank among the top few in all of history.
