Mai Jiacheng, while speaking, had already swung his fist towards Su Tong's face.
Clearly, Mai Jiacheng had a domineering character and wasn't very intelligent. Once someone put the idea in his head, he immediately believed Su Tong was the murderer who harmed his grandfather.
Despite his age, Su Tong was still a third-rate expert. Seeing Mai Jiacheng's fist coming, he lightly shifted to the side, dodging Mai Jiacheng's punch.
Having missed with his punch, Mai Jiacheng's eyes flashed with surprise, but he quickly became furious and pointed at Su Tong, shouting, "Well, you really do have a problem. You, an old man, still have such skills. It seems you've been planning to harm my grandfather for a long time!"
Although Mai Jiacheng usually trained, he had no interest in Huaxia's kung fu. Instead, he was very interested in Korean Taekwondo and similar things.
Until now, Mai Jiacheng had barely reached the level of a black belt.
