Emperor Qing summoned Chen Pingping to confront the eldest princess. The eldest princess pointed out that Fan Xian had met Yan Bingyun before entering the capital and pointed out that he was also suspected of collaborating with the enemy, but she unexpectedly fell into Chen Pingping's trap.Fan Xian's meeting with Yan Bingyun was a top secret of the Inspection Institute. The eldest princess's move exposed the fact that she was an insider in the Inspection Institute.The Inspection Institute is directly under the jurisdiction of Emperor Qing. The eldest princess's intervention in the Inspection Institute is a test of the monarch's authority, which Emperor Qing will not tolerate.Chen Pingping told Fan Xian that the next step is to find out the eldest princess's insider in the inspection institute.After Yan Ruohai learned of the eldest princess's collaboration with the enemy, he told Zhu Ge that he would intercept the Northern Qi envoy in the woods outside the countryside to testify that the eldest princess was treason.At night, when Yan Ruohai led his people to start an operation in the woods on the outskirts, Zhu Ge arrived and wanted to take Yan Ruohai's life.
