Su Yang actually intended to let Zhao Ping'an make the decision because using the Hu Family's people purely for their martial prowess was not particularly effective.
As the saying goes, a combination of kindness and severity is the best way to deal with subordinates.
Previously, killing so many people was meant to intimidate. Now, Zhao Ping'an stepping forward to save these people's lives and properties of the Hu Family was an act of kindness.
From the expressions of the Hu Family's people, Su Yang could tell that they were now completely submissive to Zhao Ping'an. Without a doubt, with Zhao Ping'an in control of the Hu Family, these people would certainly serve him wholeheartedly in the future.
"Good!" Su Yang nodded, "Since Ping'an has spoken thus, we'll handle it this way. Patriarch Hu, I hope you won't disappoint me. The next time I visit Liuan City, I'd rather sit together and drink, instead of facing each other with swords drawn like today—that would not be good."
