A quarter of an hour later, the two yamen brought things in and placed them in the hall.
The three adults glanced at the equipment, then turned to look at Xu Qi'an.
Chen Fuyin said in a deep voice: "Everything you want is here, you must give this official a satisfactory answer."
His attitude changed.
For a quarter of an hour, the official of the fourth grade 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 had not been solved, such as the fact that the tax silver fell into the river.
There is some mystery in it, he can't understand it.
"If Caomin helps the lord solve this case, can you write to the saint to absolve my Xu family of guilt."
Dafeng attaches great importance to the inheritance of father and son, and the son can pass on the father's behalf, and he can also make meritorious deeds on behalf of the father.
"Naturally." Chen Fuyin nodded.
Xu Qi'an nodded and crouched down in front of the utensils. The props in front of him were candles, salt, porcelain cups, and iron wires.
What he has to do is simple, high school chemistry knowledge: extract sodium metal.
In ancient times, it was impossible to extract this thing. There were 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 Sitianjian Warlock: Alchemist!
Alchemists are a well-known profession in Dafeng, and their various inventions and creations have long been integrated into the lives of ordinary people.
Xu Qi'an was not sure that the exploding tax silver must be sodium metal. This is not important. What is important is to open up an idea to explain the phenomenon of tax and silver explosion.
In the process of deciding a case, bold assumptions and rigorous reasoning are necessary tasks in the early stage. The last step is to verify and collect evidence.
In a previous life, he had encountered a murder case that made him fresh in his memory. The criminal policemen worked all night, opened their brains according to the clues, made several speculations about the process of the case, and collected evidence based on this.
Then it was overturned and re-reasoned.
It is also possible that the tax silver is not sodium metal, in short, the alchemist can do it.
This is enough.
To find the right direction for several adults, this is what he has to do.
If the direction is right, you can follow the clues to investigate, and it is not difficult to find out who is behind the scenes.
If you are still struggling with the idea of monsters, 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 kosher salt with water, and after stirring, he covered the shengxuan on the mouth of the cup, and slowly poured the brine.
After straining, the porcelain cups are roasted over candles, stirring constantly with bamboo skewers.
After a while, the brine in the cup evaporated to dryness, and the crystals precipitated inside were sodium chloride.
The essence is to further purify the salt.
Chen Fu Yin, a middle-aged man, and a beautiful girl in a yellow dress stood on the sidelines and watched intently.
Xu Qi'an raised his head and grinned at the girl in the yellow skirt: "Your Excellency is a disciple of Si Tianjian, right?"
He noticed the feng shui disc around his waist. No one except the disciples of Si Tianjian knew how to use it.
The girl in the yellow skirt gave an 'um' and said with a smile, "The tutor is the supervisor of the Sitian Supervisor."
The delicate and bright oval face is like a peeled egg, white and flawless.
The disciple of Jianzheng... It doesn't matter if you have breasts or something... Xu Qi'an said in a gentle tone, "Please, sister, melt these crystals for me."
The melting point of sodium chloride is about 800 degrees Celsius.
The girl in the yellow skirt shrunk her small mouth: "Controlling fire is the ability of an alchemist. I'm just a geomancer."
"But my master gave me a magic weapon." She changed her words, took off the feng shui plate around her waist, fiddled with her green jade fingers a few times, entered the qi machine, and the word "fire" lit up.
"Back off!"
Xu Qi'an immediately stepped back, and the next moment, the bright and dazzling flames spit out, submerging 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 Leifa! Pay attention to controlling the voltage... Well, this step is difficult, maybe it will Failed many times."
She turned the feng shui plate, and the green jade finger lit up the word 'thunder', and several arcs flashed in the void, touching the wire.
'Ziz....' The molten sodium chloride undergoes a violent chemical reaction.
"stop!"
Xu Qi'an held his breath and leaned to the mouth of the cup to see that a lump of bright silver metal was formed, with some unconverted crystals and impurities on the edge.
It was a success in one go, the voltage was just right... Xu Qi'an was pleasantly surprised.
The electrolysis method is used to produce sodium metal, and the voltage is about 6-15 volts. He is prepared for repeated failures.
Unexpectedly, Emperor Ou was possessed, and it was done at one time.
Chen Fu Yin and the middle-aged man couldn't wait to look closely. Inside the cup was a lump of silver metal. 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 hard and stared blankly at the silver metal block, as if lightning struck in his mind, splitting all the fog.
"Several adults, please take a look," Xu Qi'an poured out the sodium metal, wrapped it in rice paper, and weighed it in his hand:
"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 faked? A few adults can also weigh it."
He handed the sodium metal to Chen Fuyin. At this time, the color of the sodium metal gradually turned dim, almost exactly the same as silver.
The middle-aged man took it and weighed it. His eyes were shining, and he continued: "It's really lighter. If this is the thing that is being transported, it makes sense. Miss Caiwei, try it."
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'm not, I'm just a chemical porter.
The scholar's thinking is more active. After Chen Fuyin was pleasantly surprised, he suddenly shook his head and said solemnly: "No, no, even if the silver was replaced like this. What happened to the explosion? If there were monsters hidden in the river, the fake silver entered the water. How could it explode."
Xu Qi'an didn't answer, he stretched out his hand to take the metal sodium, walked to the desk, and threw it into the pen washing tub.
A blazing fire lit up, and thick smoke billowed.
"boom!"
The sodium metal reacted violently in the water, and the pen-washing tank burst into fine cracks.
"This, this..." Chen Fu Yin was stunned.
"This fake silver will explode when it encounters water. This can explain why the silver will explode so violently after falling into the water." Xu Qi'an explained.
The middle-aged man murmured: "From the very beginning, we were misled. The mastermind behind the scenes used explosions and demonic winds to make us think that it was a monster, and the focus of the investigation was on tracking and searching."
"No wonder Qin Tianjian's qi-looking technique can't detect 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 are spread on the top layer to hide people's eyes."
Strictly fit, all anomalies are right.
"Xu Qi'an!" The middle-aged man's eyes were full of approval: "Okay, you are fine."
His brows suddenly wrinkled, and solidified on Xu Qi'an's slanted neckline. Li Yuchun then patted his shoulders to help him pull his neckline neatly.
Xu Qi'an was flattered that this adult appreciated him so much.
Chen Fuyin frowned and said, "Since the silver is fake, where is the real silver?"
The girl in the yellow dress also showed a solemn look when she heard the words: "Taxes and silver are transferred out of the treasury and into Beijing, and they change hands at different levels. If they want to be convicted, a large number of officials will be imprisoned. The difficulty of recovering the silver is like finding a needle in a haystack. And this matter is beyond us. The terms of reference must be reported to Your Majesty."
Chen Fu Yin nodded, that's what he meant.
The middle-aged man had a different opinion, and his voice was low: "Taxyin was escorted all the way into Beijing, and changed hands layer by layer. If it was fake, it would have been discovered long ago. The only possibility is that the package was dropped recently."
Chen Fuyin's eyes lit up, this greatly narrowed the scope of the investigation.
"Come here, prepare the sedan chair, prepare the sedan chair quickly, this official wants to leave." Chen Fuyin rushed out of the inner hall eagerly.
Middle-aged men follow.
Xu Qi'an hurriedly shouted: "Master Fu Yin, don't forget your promise to the grass people."
