Similar to the Heavenly Emperor of the Solitary Destructive Heaven, Feng Qing Yang, Su Li specialized in the law of destruction. For this reason, Feng Qing Yang had invited Su Li to stay with him for a time to guide him.
It was impossible for Feng Qing Yang to teach Su Li as he would Duan Ling Tian; the most he could do was help Su Li gain a better understanding of the law of destruction.
However, although Feng Qing had openly shared his knowledge of the law of destruction with Su Li and answered many of the questions that had been bothering Su Li, due to law of destruction's difficulty, Su Li needed more time to apply what Feng Qing Yang had taught him. Hence, Su Li did not improve much since Feng Qing Yang last saw him because he had yet to fully grasp Feng Qing Yang's words.
Swoosh!
