The original opponent's greatest concern when facing the young master was his use of joint weaknesses, but now, after some time to get accustomed, targeting those commonly used joint weaknesses had become less effective. The opponent could now successfully extricate himself from the young master's clutches during those occasional entanglements.
This meant that he was no longer so passive when facing the young master's attacks.
In previous battles, this opponent of the young master had never shown such familiarity with joint techniques.
"Is he hiding his skill, or is he learning?"

The attacks were always interrupted before they could land, and the rare counterstrikes could hardly be executed with perfect force. This frustrating feeling was enough to make one want to spit blood.
