It was not that Tang Shaoyang did not believe that a certain issue needed to be solved with words. But he was sure the issue with Mayor Tomas was not the one that could be solved with words.
This man had been in the highest rank in the town for years, he was not going to tolerate someone stronger than him to step into his pride just like that. Not selling the beastmen and the Dark Predator to him was a humiliation to the man, yet Ashley added it with a threat as well. The Mayor would return with more people with him and tried to return the humiliation on them.
Everything happened as Tang Shaoyang predicted, it was no different compared to gang conflict. It was about pride and power. He believed that Mayor Tomas made this big so others could see what would happen to someone who offended him. Tomas wanted to use him as an example to the others.
