Cai Wei looked for Xu Qi 'an and told him the inside story of the tax case.
Xu Qi 'an first detected the problem with the tax silver through the journey of the tax silver and the weight of the silver. Then he explained his reasoning process, including the analysis of the suspicious points. For example, if the escort personnel wore hand guards when counting the silver, he would have solved the case in this way.

Xu Qi 'an first detected the problem with the tax money through the journey of the tax money and the weight of the silver. Then he told him his reasoning process. For example, he would think about whether there were any clues in the case because he believed that there was no perfect crime in the world. Other than coincidence, any man-made case could find clues. Of course, if Second Uncle Xu could provide a more complete confession, such as the details of wearing a hand guard, Xu Qi 'an could analyze the truth of the case faster.
Xu Qi 'an was bullied by Zhou Li when he took his sister out shopping to catch butterflies. When he tried to stop her, he was beaten up and brought back to the Yamen. The county magistrate failed to stop him and was arrested by the Ministry of Justice. He had sent Arrester Wang to invite Cai Wei, and after learning about the inside story of the tax case, he went to the Directorate of Celestials to teach Song Qing how to refine Na, and exchanged it for the black gold knife and many magic tools that the supervisor had refined. He had even discussed with his family about dealing with Assistant Minister Zhou.
Xu Qi 'an relied on the experience he had learned from the police academy in his previous life to investigate the scene and analyze the clues. He might have found clues from the amount of tax money, the details of the transportation process, the performance of the relevant personnel, and so on, thus finding the key to solving the case.
Xu Qi 'an detected the problem with the tax money through the transportation route and the weight of the silver, and then told him his reasoning process. First, he found some suspicious points from the distance and weight, and then he carried out a detailed analysis to finally solve the case.
In the tax case, Xu Qi 'an asked Xu Xinnian to write down the details of the case file. After Chu Caiwei, Yang Yan, and the magistrate failed to investigate the scene, Xu Qi' an solved the case and confronted the three of them. He told them the case and refined the fake silver.
Xu Qi 'an was clamoring to see the magistrate in prison, saying that he had important clues to report. Then, the magistrate solved the case. According to the law, Xu Qi 'an would be exonerated.
Xu Qi 'an had played a key role in opening up a new line of thought in the tax case. He explained the phenomenon of the tax silver explosion by extracting the metallic Na. First, he used water to melt the coarse salt, then filtered it, roasted it, and other steps to obtain the crystal of the salt. With the help of the yellow dress girl's magical equipment to complete the relevant reaction, he obtained the metallic Na that was similar to silver, proving that it was lighter than silver and would explode when it came into contact with water. From this, he inferred that the tax silver might have been replaced, and the explosion was due to this reason rather than the demon. This provided a new direction for the investigation of the case, and also pointed out that the real silver might have been replaced recently. This greatly reduced the scope of the investigation.
After the initial interrogation and torture, Xu Qi 'an was determined to be an irrelevant person who had nothing to do with the case. There was no further explanation in the reference knowledge.
