Chapter 73: Yeomra
Now that he had taken care of the vengeful souls, he had to deal with the corrupted blood essence. He needed to absorb all the corrupted blood essence and seal it in the black and red lotus in his Middle Energy Core. From then on, he could slowly absorb it. It sounded fairly simple, but it was actually very dangerous because to reach the Middle Energy Core, the corrupted blood essence had to circulate inside his meridians.
Just the fact that something other than qi was being circulated in the meridians would cause soul-crushing pain, not to mention a substance that would actively try to corrupt him. But he saw this as an opportunity to make his meridians even more tenacious.
He sat down and imbued Sasin with his Hell Qi. He had obviously done this before, but this time, he reabsorbed the Hell Qi back into his body instead of using it up in an attack. The corrupted blood essence seemed to have found an outlet and rushed into his meridians along with the Hell Qi.
