Su Fan is very young, and even though he possesses the strength of a Martial Arts Grandmaster's mid-level, at this stage, he hasn't had time to accumulate and deepen his skills!
This results in Su Fan having little True Qi within him.
Su Fan continues to retreat, using defense as offense.
After a brief exchange, he understood Sun Zhuoda's intention.
Although Sun Zhuoda is a brute, his judgment in martial arts isn't entirely off the mark.
Su Fan indeed just recently broke through to become a mid-level Martial Arts Grandmaster, without any time for accumulation or deepening.
If Sun Zhuoda weren't very formidable, Su Fan would still hope to reserve some techniques.
But Sun Zhuoda is a Taiji expert, and a very skilled practitioner of Taiji energy redirection.
Thus, he couldn't continue to hold back.
He stopped competing with Sun Zhuoda in bare-handed combat and quickly moved toward the woods, retrieving the Cold Spring Sword he had hidden behind a tree.
