For Xiao Qiang, had he not noticed the fierce glint in Liu Hua's eyes after watching Li Yuan, he would have let those guys go. After all, on one hand, it was a public place and it wasn't fitting for him to kill, and on the other hand, Xiao Qiang hadn't reached the cruel stage where words would lead to violence.
However, when Xiao Qiang noticed Liu Hua's malicious look as he was secretly watching Li Yuan, he changed his mind.
From his many years as a martial artist, Xiao Qiang had learnt the importance of eliminating evil. He had seen good people spare the lives of bad ones due to their belief in the inherent goodness of life, only to have the bad ones eventually annihilate them and their entire families. Xiao Qiang, dealing with those who wished to harm him, always held the attitude of efficiently handling anyone showing intentions of revenge. Like Liu Hua, if he didn't deal with him today, Li Yuan would certainly fall victim to his revenge.
