That person's endurance training was too outstanding.
Elder Pan's heart skipped a beat. Even his most powerful attack could not wound Ali sufficiently. Moreover, the areas that went in contact with Ali would be numb after each exchange. If it was a one on one fight, he would not have lasted long.
Fortunately, Elder Sun would continuously back him up with attacks using his inner force. With the two of them working together, they were able to keep Ali suppressed.
"Hmph!" Ali grunted as his aura weakened.
He held his ground and continued the fight with Elder Pan, but the strength in his bloodied right arm was much weaker than before.
Elder Sun was harassing him with inner force while Elder Pan clawed at him, continuously leaving claw marks on Ali's body. Although they were unable to defeat Ali in a short time, those small wounds would add up and Ali's condition would only worsen.
