Ye Qing's inner strength is very powerful now, but the intensity of his meridians is insufficient, and that's his greatest limitation.
Ye Qing's inner strength has completely reached the level of the Five Uniques. Although Northern Fist King Li Changqing was poisoned twenty years ago, Northern Fist King Li Changqing had already reached the level of a pinnacle master twenty years ago. This means that even if Li Changqing hadn't been poisoned and continued practicing martial arts over these twenty years, his inner strength wouldn't have advanced in the slightest.
Because, as Helian Tiehua once said, the standard to judge a pinnacle master is to see if a person's inner strength has reached its peak. Pinnacle means no more beyond it, nothing can surpass pinnacle, and that's why it's called pinnacle.
