The Scarlet King saw how only his Essence Wave and Blood Energy (Essence) had improved. Still, it made sense as he knew that the Essence Evolution Path of Power would lack the capabilities to temper his body for a long time, even if he practiced auxiliary techniques.
"27 points. I have suppressed and tempered my energy pool as much as possible, but it has already reached its limit."
The Scarlet King had been using top-tier resources and energy to improve the Essence Wave of his Evolution Core, and it was a stark contrast to the wild energy present when he recently entered the Early Stage. Training the Dark Blood God Phantom Technique also had wondrous effects on his energy and perception, improving his mastery of the Law of Blood and Law of Darkness.
However, he had already reached a blockade, and if he wanted to keep improving, it was time to allow his Evolution Core's energy to rise to the next level.
