"Judging by grade alone, the black energy is evidently inferior to the Li Fire Technique. It's just that the damned Zong's mana is more robust, his cultivation level stronger, hence he can suppress the Li Fire Technique, right?"
Su Xing roughly made a judgment in his mind and looked at the simulation panel.
[You fought like this for over ten rounds, noticeably feeling the excessive depletion of spiritual power. Even though you reached the Great Perfection of the Nascent Soul Stage, the Li Fire Technique still consumed a significant amount of your spiritual power when unleashed to its fullest.]
[What shocked you even more was that the black energy seemed to be constantly eroding the spiritual energy of the Li Fire Technique, causing your spiritual power consumption to increase drastically. You had to continuously absorb Spirit Stones to maintain your energy.]
