"How could I not know? The Prime Minister must have spies in Mo City. Nothing could be hidden from him."
Cheng Yu shook his head. He couldn't believe that Su Qing had any good ideas.
"Then use this spy."
Su Qing smiled. If she could use Liu Hong to lure Ye Changheng out, she could use Prime Minister Wan's spies to achieve her goal.
Seeing the confidence in Su Qing's eyes, Cheng Yu felt convinced. He asked Su Qing,
"You already know who the spy is?"
"I don't know for now."
Su Qing shook her head. When Cheng Yu heard her say she didn't know, the hope in his eyes disappeared.
"If you don't know who the spy is, how can you use him?"
"That's easy. Let's do a good job. Who did Chief Zhu come into contact with after entering the city? Including who he had talked to and met face to face with. Find them and interrogate them one by one."
