Only the dead wouldn't speak and spill secrets!
They were loyal to their master, but not if their master wanted them dead. For a moment, some of them wavered, and some even had thoughts of rebelling.
When the leader saw this, he shouted angrily at Jiang Zhennan, "Jiang Zhennan, don't you try to sow discord here! If master really wanted to silence us, he wouldn't have rewarded us with ten thousand taels of gold. That's contradictory!" Then, he turned around and shouted angrily at those people, "Don't be incited by him. He just wants to make a chink in our minds. Don't fall for his trick!"
After he finished shouting at his subordinates, he then said angrily to Jiang Zhennan, "Jiang Zhennan, you're really asking for it. I was planning to keep your corpse intact at first, but you lost your chance. After all, we only need your head. As for your body, I'm sure it'll feed plenty of wildlife."
