Xu Xuan closely followed behind him, like a cat playing with a mouse, pressing step by step, yet not to the point of forcing him into a dead end.
This was intentional on Xu Xuan's part.
Because this guy had yet to reveal his trump card, it felt like he was holding something back.
Before forcing his opponent's trump card out, Xu Xuan was not going to strike a killing blow.
When experts clash, whoever unleashes a lethal move first is the one who exposes their trump card as well as their own defensive gaps. While killing someone else, one also reveals their most significant vulnerability.
Since this guy wanted to hide, then let him keep on hiding, gradually wearing down his strength is sufficient.
