Jiang Cheng wasn't foolish; he could see that these people were all acting out of greed for the treasure.
Not to mention keeping himself safe, even if he could, they'd definitely turn on him afterward.
So while taking off his outer robe, he exposed all those old schemers who were secretly sending voice transmissions.
"Sigh, there's no need to whisper, everyone. Let me be clear, I don't have the treasure you're talking about."
After removing the outer robe, he gave it a shake.
"If you don't believe me, have a look."
He was going to die soon anyway, and the robe would be destroyed if not taken off.
"I really don't have it. I don't even know why you think I have a lot of Tier Nine Spirit Talismans."
"The one from last time was just a coincidence—it was only one!"
He looked innocent, desperately trying to prove his 'innocence.'
