I think I understand...
Through this sparring match, Su Xuan suddenly had a revelation. The iron staff seemed to possess a strange, repulsive magnetic force capable of deflecting an opponent's weapon. The greater the force behind the opponent's strike, the stronger the staff's repulsive force became, until it shattered the weapon entirely.
He also had a theory, though he couldn't be certain. He suspected the iron staff might also possess a magical ability to weaken an opponent's weapon, rendering it fragile. This was a theory he would need to verify later.
"I... I've lost!"
After being revived by his companions, Du Zilong slowly regained consciousness. He looked at Su Xuan, his defeat total and heartfelt. He didn't think Su Xuan's iron staff was particularly formidable. Instead, he believed Su Xuan's control over the forces of Tai Chi had reached a terrifying level, allowing him to destroy his Tai Chi sword and knock him on the head in the blink of an eye.
