He took it out, and it turned out to be a small pouch stained with blood.
Yes, the thing in his mouth was what he had just used to pretend he was coughing up blood.
Simply put, it was akin to a blood packet from later generations.
However, the packet didn't contain chicken blood, duck blood, or pig blood, but real human blood.
As for why he didn't use animal blood, it was entirely because Daoist Wu was too familiar with Prince You.
He knew Prince You's insidious, cunning, and suspicious nature.
To make sure everything was foolproof, he directly made a small cut on himself, drawing out a small bag of fresh blood and placing it in his mouth.
As for why he didn't use someone else's blood, he was entirely afraid that Prince You would detect it.
Of course, even the small pool of blood left in the grand hall was deliberately spilled there by him.
He believed that after he left, Prince You would definitely have someone investigate it.
