One of the merchants asked, "How can you prove that the evidence is conclusive?!"
Su Binglan said, "Not only did you kill a few from Yang County, but you also killed your uncle. Your family can testify to it. Do you want me to call them here?"
Suddenly, a villager shouted, "We can testify against him, Princess Binglan! He killed many people from Yang County! He's inhumane and doesn't even spare children!"
"Your Highness, we can testify against all of them. They're all killers!"
…
More people gathered at the scene and began to criticize the merchants. Su Binglan ordered someone to beat the merchants with a cane, "Give them fifty strokes each."
She seemed gentle and easy to talk to, but she would show no mercy when she was angry. Soon after, the merchants were half-dead. Su Binglan would not kill without reason, but she would have to kill these merchants according to the law.
