Zhou Jia obtained evidence of the Cheng family colluding with Magistrate Feng to sell iron ore and did not need to investigate other evidence. He told Ruyi and the secret guards not to return to the posthouse but to prepare to bring them to Qingyue Mountain the next morning.
He wrote another letter and asked Zhao Cai to go to the courier station to get the soldiers to hand the letter to Judge Wu and tell him that he had brought people to the various counties and towns below to check.
Thinking of the woman who had sent the letter, he was afraid that the Cheng family and Magistrate Feng would search for her whereabouts after finding out that she had left. He said to Ruyi, "Go to Causeway Lane and bring the Wu couple to the grocery store. Get Chu Shan's people to find a place to hide them."
