This was because he could tell that this swordsman was indeed old. The momentum of his attack was not as exaggerated as when he used the Yellow Dragon Crouching in West King Town. He wasn't his match at all.
But this sword strike was equally skillful, and the mastery had even reached the point where it was almost incomprehensible.
At first, Ye Jingtang's punches and spear strikes would shatter his clothes. It seemed that his momentum was earth-shattering, but in fact, his qi had been too scattered, and he couldn't concentrate his strength.
But now that he had learned to control it, he could suppress all his qi in the blade. When he attacked, he used his strongest saber move without any waves. Only when he used his full strength would he be unable to suppress his qi, causing his qi to overflow.
The black-robed old man's all-out sword strike had caused such a shocking commotion, but his deep internal energy was clearly still controllable.
