Jiang Yue and Xue Yan knew that Fan Jianxi must have reported everything to Shi Yuan. However, it had only been ten days, and Fan Jianxi was not sure who had taken the things in the secret chamber. He should have observed any signs for a few days before making a decision. If Shi Yuan had not just learned about the things he had reported, or if the memorial or letter was still on the way, Shi Yuan would not have known.
Qiu Pusheng had something on the current Prime Minister. Besides, the Prime Minister himself was involved in the heavy taxes in Lizhou. Usually, the Prime Minister would help to sort out the memorials. If the Prime Minister saw it, he would probably help Qiu Pusheng suppress it. It was unlikely that Shi Yuan would know about this.
This meant that Fan Jianxi must have sent a letter.
