A quarter of an hour later, two yamen servants brought the 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, and you must give me a satisfactory answer."
His attitude has changed.
For a quarter of an hour, this fourth-rank official racked his brains for a long time, and had to admit that Xu Qi'an's deduction was reasonable, but there were still many mysteries that had not been solved, such as the fact that the tax bank fell into the river.
What is the mystery in it, he can't understand it.
"If the grass-roots help the adults to solve the case, can you write to the saint to exonerate my Xu family from the crimes?"
Dafeng attaches great importance to the inheritance of father and son, and the son can also perform crimes and meritorious deeds on behalf of the father.
"Naturally." Chen Fuyin nodded.
Xu Qi'an nodded, and squatted 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 metal sodium.
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 Sitianjian Warlock: Alchemist!
Alchemists are well-known occupations in Dafeng, and their various inventions and creations have long been integrated into the lives of ordinary people.
Xu Qi'an is not sure that the tax silver that exploded must be sodium metal, 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 deciding a 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 was still fresh in his memory. The criminal police stayed up all night, opened up their brains based on clues, made several speculations about the course of the case, and used this as a basis to collect evidence.
Then they all overturned and reasoned again.
It is also possible that tax silver is not sodium metal, alchemists can do this anyway.
This is enough.
Finding 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 thinking of monsters making trouble, the case will never be solved. Even if the case is solved in the future, he will have already sent you to the court: send you away, thousands of miles away!
He melted the coarse salt with water, and after stirring, covered the mouth of the cup with raw rice, and poured the salt water slowly.
After filtering, put the porcelain cup on the candle and bake it, stirring constantly with a bamboo skewer.
Not long after, the brine in the cup evaporated to dryness, and the crystals that precipitated inside were sodium chloride.
The essence is to further purify the salt.
? Chen Fuyin, a middle-aged man, and a girl in a yellow skirt with super good looks, the three of them stood on the sidelines and watched intently.
Xu Qi'an raised his head and grinned at the girl in the yellow skirt: "My lord is the disciple of Si Tianjian, right?"
He noticed the feng shui dish on his waist, no one knows how to use this thing except Si Tianjian's disciples.
The girl in the yellow skirt gave an 'hmm' and said with a smile: "The tutor is Si Tianjian."
The delicate and bright oval face is like a shelled egg, white and flawless.
A disciple of Jianzhengit doesn't matter what the chest isXu Qi'an said softly, "Sister, please melt these crystals for me."
The melting point of sodium chloride is about 800 degrees Celsius.
The girl in the yellow skirt pursed her mouth: "Controlling fire is the ability of an alchemist, and I'm just a feng shui master."
"However, my master gave me a magic weapon." She changed the topic, took off the Feng Shui tray around her waist, fiddled with her green fingers a few times, input the Qi machine, and the word "fire" lit up.
"Stand back!"
Xu Qi'an backed away immediately, and the next moment, a tongue of bright and dazzling fire spewed out, submerging the porcelain cup.
"Stop!" Xu Qian yelled to stop immediately, then quickly inserted two iron wires into the porcelain cup, and asked, "Power onno, it's Leifa! Pay attention to controlling the voltagewell, this step is difficult, maybe it will Failed many times."
She turned the feng shui dish, and the green onion jade finger lit up the word 'thunder', and several arcs flashed in the void, touching the wire.
'Zizi' The molten sodium chloride undergoes a violent chemical reaction.
"stop!"
Xu Qi'an held his breath, leaned over to the cup to look, and saw that a lump of bright silver metal was formed, with some untransformed crystals and impurities on the edge.
It was successful in one go, the voltage was just rightXu 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, the possession of the Emperor Ou would be accomplished in one go.
Chen Fuyin and the middle-aged man couldn't wait to look over their heads. Inside the cup was a lump of silver metal. At first glance, it was quite similar to silver.
Chen Fuyin's pupils shrank, and his heart was extremely shocked.
Li Yuchun clenched his fists hard, staring blankly at the silver metal block, as if lightning struck in his mind, splitting all the fog.
"Sirs, 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, much lighter than silver, but its appearance is very similar. If someone uses this thing to pass off silver, can it be mistaken for real? Several adults can also weigh it."
He handed the metal sodium to Chen Fuyin. At this time, the color of the metal sodium gradually turned dark, almost exactly the same as silver.
The middle-aged man took it and weighed it. His eyes sparkled, and he said repeatedly: "Sure enough, it is much lighter. If it is this thing that is being transported, it would be reasonable. Miss Caiwei, try it."
The girl in the yellow skirt took it, weighed it, and then stared at Xu Qi'an with strange eyes: "You, are you an alchemist?"
No, I'm not, I'm just a chemical porter.
Scholars are more active in thinking after all. After Chen Fuyin was pleasantly surprised, he suddenly shook his head and said in a deep voice: "No, no, even if the silver is replaced like 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, reached out to take the sodium metal, walked to the desk, and threw it into the pen washing bowl.
The blazing fire was lit, 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 Fuyin was stunned.
"This fake silver will explode when it encounters water. This can explain why the silver explodes so violently when it falls into the water." Xu Qi'an explained.
The middle-aged man murmured: "From the very beginning, we were misled. The behind-the-scenes mastermind used the explosion and the evil wind to make us think that it was a monster. The focus of the investigation was on tracking and hunting."
"No wonder Qin Tianjian's qi-watching technique can't detect monsters."
Xu Qi'an added: "After the tax money fell into the water, the soldiers only recovered more than a thousand taels of silver. If you guessed correctly, the silver was spread on the top floor to hide."
It fit perfectly, and all abnormalities were aligned.
"Xu Qi'an!" The middle-aged man's eyes were full of approval: "Okay, you are fine."
A frown suddenly frowned, froze on Xu Qian's crooked neckline, and Li Yuchun continued to pat his shoulders to help him straighten his neckline.
Xu Qi'an was flattered that this adult appreciated him so much.
Chen Fuyin frowned and said, "Since the money is fake, where is the real money?"
The girl in the yellow skirt also showed a dignified expression when she heard the words: "The tax money goes out of the warehouse and enters Beijing, and it changes hands layer by layer. If you want to question the crime, a large number of officials will have to be imprisoned. The difficulty of recovering the money is like looking for a needle in a haystack. And this matter has surpassed us. The scope of the authority must be reported to His Majesty."
Chen Fuyin nodded, that's what he meant.
The middle-aged man had a different opinion, and his voice was low: "The tax bank was escorted all the way to Beijing and changed hands layer by layer. If it was fake, it should have been discovered long ago. The only possibility is that it was recently dropped."
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, I want to go out." Chen Fuyin rushed out of the inner hall eagerly.
The middle-aged man followed closely behind.
Xu Qi'an hurriedly shouted: "Master Fu Yin, don't forget your promise to the grassroots." (Remember the website website: www.hlnovel.com
