One had to know that at Chen Nianzhi's realm of cultivation, his physical body had nearly reached the point where there was no further room for advancement. To gain another twenty percent in base defense was already an enormous breakthrough.
"To withstand the attacks of the Limitless Sovereigns, my base defense is still somewhat insufficient."
