Xu Qi 'an first started with the confession of the guards at the city gate. He raised questions such as the weight of 150,000 taels of silver, the distance from the city gate to Guangnan Street, the number of busy cities on the way, the journey of the bad horse, etc. He pointed out the unreasonable time, and then inferred that the silver was not escorted at all. From then on, the officials began to believe that the tax silver case was not done by demons.
Xu Qi 'an used his high school chemistry knowledge to extract the metal Na to explain the phenomenon of the silver tax explosion. He first used water to melt the coarse salt. After stirring it, he covered the cup with the raw salt and slowly poured in the salt water. After filtering it, he placed the porcelain cup on the candle and roasted it. He stirred it with a bamboo stick to obtain the crystals of the salt. Then, he had the girl in the yellow dress melt the crystals with the magical equipment given by the supervisor, and then insert the iron wire. He had the girl in the yellow dress control the voltage with the lightning method, and then produce metallic Na by electrolysi. Finally, through the characteristics of metallic Na being lighter than silver and exploding in water, he explained the mystery of the tax silver case and opened up a way for the officials.
Xu Qi 'an used the experience he learned from the police academy in his previous life to solve the tax case.
Xu Qi 'an was involved in the tax case because his second uncle, Xu Pingzhi, was responsible for escorting the tax money. As Xu Pingzhi's nephew, Xu Qi' an was implicated in the robbery. He was interrogated and tortured by the Jingzhao government yamen. At first, he was determined to be an irrelevant person who had nothing to do with the case. Later, he was given important clues through his own reasoning.
Because the team escorting the tax silver encountered a demon wind, the tax silver exploded after falling into the river. These two obvious clues made the Jingzhao government yamen think that it was a demon. Demons did things as they pleased. In addition, the appearance of the demonic wind made everyone feel that there were cultivators involved, so they initially judged it to be the work of demons.
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 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 silver through the journey and the weight of the silver. Then he told her his reasoning process, such as deducing from some neglected details in the confession.
Xu Qi 'an first detected the problem with the tax silver through the transportation route and the weight of the silver. Then, he told him his deduction process. He could find problems from these aspects because there was no perfect crime in the world. Other than coincidence, any man-made case could find clues.
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.
