Chu Zhiyuan said, "I won't mistake it, there is indeed a black line... neither of us has it, but Senior Brother Ning does."
Zhang Ji Yuan laughed, "Could it be because our cultivation level is not as high as Senior Brother Ning's?"
"Nonsense," Ning Dongge said, "You two are both at perfection, the same level of cultivation, how could you be inferior to me?"
"Senior Brother Ning, you are still a cut above the rest," Zhang Ji Yuan laughed.
Chu Zhiyuan shook his head, "I guess it's not because of cultivation."
"What do you mean by that?" Zhang Ji Yuan asked.
Chu Zhiyuan said, "If it is because of cultivation, why can't Brother Zhang see this black line?"
"Hmm... because of different cultivation techniques?" Zhang Ji Yuan thought for a moment, "But my technique is similar to Senior Brother Ning's, not much different, it's you who practice something different."
