Finding Sun Zu and discussing things with him shouldn't have been an issue.
However, it was only not an issue in theory from Sky Canine Supreme's perspective.
Why?
Because from the very beginning when Sky Canine Supreme tried to find Sun Zu, there was already a huge problem with his approach. The other party clearly didn't intend to bow down and humble themselves. Instead, they planned to appease Sun Zu directly, then solve the problem from Sun Zu's angle, and finally let Sun Zu resolve the issue with Yang Chen.
Then, everything would be fine, and there would be no more problems.
To put it bluntly, they didn't take him seriously at all.
The other party was even worse than Zhang Wudao. At least Zhang Wudao knew who to apologize to. This Sky Canine Supreme disregarded him completely and went straight to Sun Zu to solve the problem?
Yang Chen was, of course, angry.
