Chapter 5: Solve the puzzle

　　 A quarter of an hour later, two government officials brought the things in and placed them in the hall.
　　 The three adults scanned the equipment, then turned to look at Xu Qi'an.
　　 Chen Fu Yin said in a deep voice: "All the things you want are here, please give me a satisfactory answer."
　　 His attitude has changed.
　　 Within a quarter of an hour, the official of the Fourth Grade had racked his brains for a long time, and had to admit that Xu Qi'an's inference was reasonable, but there were still many doubts that have not been solved. For example, it is also true that the tax bank fell into the river.
　　 What is the mystery in it, he couldn't understand it.
　　 "If Cao Min helped your lord to solve this case, can you write a letter to the saint to excuse my Xu family from guilt."
　　 Dafeng attaches great importance to the inheritance of the father and the son. The sons live on behalf of the father, and they can also take the sins and make merits for the father.
　　 "Nature." Chen Fu Yin nodded.
　　 Xu Qi'an nodded and squatted down in front of the appliance. The props in front of him were candles, salt, porcelain cups, and iron wires.
　　 What he wants to do is very simple, high school chemistry knowledge: extract sodium metal.
　　 In ancient times, it was impossible to extract this thing. There are two difficulties: electricity and the melting point of sodium chloride.
　　 But in this world, Xu Qi'an knew that there was a profession that could do this.
　　The sixth rank of the Sitianjian Warlock: Alchemist!
　　 Alchemists are a household name in Dafeng. Their various inventions and creations have long been integrated into the lives of ordinary people.
　　 Xu Qi'an is not sure that the explosive tax silver must be metallic sodium. This is not important. What is important is to open up a way of thinking to explain the phenomenon of tax silver explosion.
　　 In the process of judging the case, bold assumptions and rigorous reasoning are necessary work in the early stage. The last thing is to verify and collect evidence.
　　 In his previous life, he had encountered a murder case that reminded him of vivid memory. The detectives opened their brains all night long based on clues and made speculations about the course of several cases. Based on this, they collected evidence.
　　 Then he overthrew everything and re-reasoned.
　　 Tax silver may not be sodium metal. In short, alchemists can do this.
This is enough.
　　 Find the right direction for a few adults, this is what he has to do.
When 　　 is in the right direction, you can follow the vines to investigate, and it is not difficult to find out who is behind the scenes.
　　 If you are still struggling with the mindset of monster chaos, the case will never be solved. Even if the case is solved in the future, he will already have the court: send you away, thousands of miles away!
　　 He melted the coarse salt with water, and after stirring, he covered the mouth of the cup and poured salt water in slowly.
　　 After filtering, put the porcelain cup holder on the candle and stir it continuously with bamboo sticks.
　　 After a short while, the salt water in the cup evaporates to dryness, and the crystals that precipitate inside are sodium chloride.
　　The essence is to further purify the salt.
　　Chen Fuyin, a middle-aged man, and a girl in a yellow skirt with superb looks, the three stood on the sideline and watched intently.
　　 Xu Qi'an raised his head and grinned at the girl in the yellow skirt: "My lord is a disciple of Sitianjian."
　　 He noticed the Feng Shui plate around his waist. No one would use this thing except for the disciples of Si Tian Jian.
　　The girl in the yellow skirt made a ‘um’, and said with a smile: "My master is Sitian Jianzheng."
　　 The delicate and bright face of an egg, like a peeled egg, white and flawless.
　　 Jianzheng’s disciple....It doesn’t matter what you breasts...Xu Qi'an said softly, "Thank you, sister, melt these crystals for me."
　　 The melting point of sodium chloride is about 800 degrees Celsius.
　　 The girl in the yellow skirt slumped her small mouth: "Fire control is the ability of an alchemist. I'm just a geomantic."
　　 "But my master gave me a magical artifact." She turned her conversation, took off the Feng Shui plate on her waist, fiddled with the green jade fingers, entered the air machine, and the word "Fire" lit up.
　　 "Get back!"
　　 Xu Qi'an immediately backed away, and the next moment, the bright tongue spit out, flooding the porcelain cup.
"Stop!" Xu Qi'an immediately called to stop, then quickly inserted two iron wires into the porcelain cup, and asked: "Power on....no, it's mine! Pay attention to the control voltage...well, this step is difficult, maybe it will Failed many times."
　　 She turned the feng shui plate, the green jade finger lit up the word ‘thunder’, and several electric arcs flashed through the sky, touching the wire.
　　 ‘Zizi...’ The molten sodium chloride undergoes a violent chemical reaction.
"stop!"
　　 Xu Qi'an held his breath and leaned over to the mouth of the cup to see, a clump of bright silver metal was formed, with some unconverted crystals and impurities on the edge.
　　 succeeded in one shot, the voltage was just right... Xu Qi'an was pleasantly surprised.
　　 The electrolysis method produces metallic sodium, and the voltage is about 6-15 volts. He is prepared for repeated failures.
　　 I didn't expect the Emperor to be possessed, it would be done once.
　　 Chen Fuyin and the middle-aged people couldn’t wait to look over their heads. There was a pile of silver metal in the cup. At first glance, it looked quite similar to silver.
　　 Chen Fu Yin's pupils shrank, and his heart was extremely shocked.
　　 Li Yuchun clenched his fists, staring at the silver metal block in a daze, as if lightning struck through his mind, splitting all the fog.
　　 "A few adults, please take a look." Xu Qi'an poured out the sodium metal, wrapped it in rice paper, and put it in his hands:
　　 "This thing is much lighter than silver, but its appearance is very similar. If someone uses this thing to pretend to be silver, can it be fake? Several adults can also weigh it."
　　 He gave the sodium metal to Chen Fuyin. At this time, the color of sodium metal gradually turned dim, almost exactly the same as silver.
　　The middle-aged man took it, and his eyes were shining, and he kept saying: "Sure enough, it's a lot lighter. If this thing is being transported, then it makes sense. Miss Plucking, you try."
　　The girl in the yellow skirt took it, weighed it, and then stared at Xu Qi'an strangely: "You, are you an alchemist?"
　　 No, I am not, I am just a chemical porter.
The scholar's thinking is more active. After the surprise, Chen Fuyin suddenly shook his head and said in a deep voice: "No, it's not right, even if the silver is replaced with this. What happened to the explosion, if it wasn't for the monster hidden in the river, the fake silver entered the water. How could it explode."
　　 Xu Qi'an didn't answer. He reached for the sodium metal, walked to the desk, and threw it into the pen washing tank.
　　 The blazing fire lights up, and thick smoke billows.
　　 "Boom!"
　　 The sodium metal reacted violently in the water, and the pen-washing tank burst into fine cracks.
　　 "This, this..." Chen Fuyin was shocked.
　　 "This fake silver will explode when it encounters water. Here can explain why after the silver falls into the water, UU reading www.uukanshu.com will have such a fierce explosion." Xu Qi'an explained.
　　 The middle-aged man murmured: "From the very beginning, we were misled. Through the explosion and the demon wind, the master behind the scenes made us think that it was a demon. The focus of the investigation was on tracking and hunting."
　　 "It's no wonder that Qin Tianjian's Qi Watching technique can't observe monsters."
　　 Xu Qi'an added: "After the tax silver fell into the water, the soldiers only recovered more than a thousand taels of silver. If you guessed correctly, these silvers were spread on the top layer for the purpose of concealing people's attention."
　　 is tightly closed, all the anomalies are aligned.
　　 "Xu Qi'an!" The middle-aged man's eyes were full of approval: "Okay, you are fine."
　　 His brows suddenly wrinkled, and Xu Qi'an's slanted neckline solidified. Li Yuchun then patted his shoulders to help him pull the neckline neatly.
　　 Xu Qi'an is flattered, this adult appreciates himself so much.
　　 Chen Fu Yin frowned and said, "Since the silver is fake, where is the real silver?"
The girl in the yellow skirt also showed a solemn color when she heard the words: "Tax and silver go out of the treasury and enter Beijing, and they will change hands at different levels. If you want to inquire about crimes, a large number of officials will go to jail. You must report to your Majesty’s powers."
　　 Chen Fu Yin nodded, that's what he meant.
　　 The middle-aged man had a different opinion, and his voice was low: "The tax and silver were escorted all the way into Beijing and changed hands one after another. If it was fake, it would have been discovered long ago. The only possibility is that it was dropped recently."
　　 Chen Fuyin's eyes lit up, which greatly reduced the scope of investigation.
　　 "Come here, prepare the sedan chair, prepare the sedan chair quickly, the official is going to go." Chen Fuyin rushed out of the inner hall eagerly.
　　 middle-aged men followed closely behind.
　　 Xu Qi'an hurriedly shouted: "Master Fu Yin, don't forget the promise to the grassroots."
