A quarter of an hour later, two officials brought in the things and placed them in the hall.

The three adults glanced at the utensils, and then turned their heads to look at Xu Qi'an.

Chen Fuyin said in a deep voice: "Everything you want is here, be sure to give this official a satisfactory answer." ”

His attitude has changed.

For a quarter of an hour, the official of Zheng Sipin racked his brains and thought for a long time, and had to admit that Xu Qi'an's inference was very reasonable, but there were still many mysteries that had not been solved, such as the fact that the tax silver fell into the river.

What is the mystery in it, he can't understand it.

Xu Qi'an nodded, squatted down in front of the utensils, and the props in front of him were candles, salt, porcelain cups, and wires.

What he had to do was simple, high school chemistry: extract sodium metal.

In ancient times, it was impossible to extract this thing, and 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 product of the Heavenly Warlock: Alchemist!

Alchemists are a well-known profession in Daebong, 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, which is not important, but it is important to open up an idea to explain the phenomenon of tax silver explosion.

In the process of adjudicating a case, bold assumptions and rigorous reasoning are essential tasks in the early stage. The last thing is to verify and collect evidence.

In his previous life, he encountered a murder case that he remembered vividly, and the criminal police stayed up all night, opened their brains according to clues, and made several speculations about the course of the case, and used this as the basis to collect evidence.

Then they all overturned and reasoned again.

It is also possible that the tax silver is not metallic sodium, but in any case the alchemist is able to do this.

That's enough.

Finding the right direction for a few adults is what he has to do.

If the direction is right, you can follow the vine to investigate, and it is not difficult to find out who is behind the scenes.

If he is still struggling with the thinking of monster chaos, the case will never be solved, even if the case is solved in the future, he will already be in the court: send you away, thousands of miles away!

He melts the coarse salt with water, stirs it, covers the mouth of the cup with raw water, and slowly pours the salt water in.

After straining, the porcelain cup is grilled on the candle and stirred constantly with a bamboo skewer.

After a short time, the salt water in the cup evaporates dry, and the crystals precipitated in it are sodium chloride.

The essence is to further purify the salt.

Chen Fuyin, a middle-aged man, and a girl in a yellow dress with super high appearance, the three of them stood on the side and watched, watching intently.

Xu Qi'an raised his head and grinned at the girl in the yellow dress: "Your Excellency is Si Tianjian's disciple." ”

He noticed the feng shui plate on his waist, this thing, except for Si Tianjian's disciples, no one would use it.

The girl in the yellow dress said 'um' and said with a smile: "The family teacher is Si Tian Jian Zheng." ”

The delicate and bright goose egg face is like a shelled egg, white and flawless.

The disciple of the prisoner.... It doesn't matter what the chest is..... Xu Qi'an's tone was gentle, "Trouble my sister to melt these crystals for me." ”

Sodium chloride is about 800 degrees Celsius.

The girl in the yellow dress pursed her mouth: "Fire control is an ability that only alchemists have, and I'm just a feng shui master." ”

"But my master gave me a magic weapon. She changed her words, took off the feng shui plate on her waist, and the green jade fingers were fiddling a few times, the qi machine was input, and the word "fire" lit up.

"Stand back!"

Xu Qi'an immediately retreated, and the next moment, the bright and dazzling tongue of fire spewed out, flooding the porcelain cup.

"Stop!" Xu Qi'an immediately shouted to stop, and then quickly inserted two wires into the porcelain cup and asked, "Power on.... No, it's Lefa!Pay attention to the control voltage.... Well, this step is difficult and may fail many times. ”

She turned the feng shui plate, and the green jade finger lit up the word 'thunder', and several arcs of electricity flashed in the void, 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 that a lump of silver bright metal was formed, and the edges were some crystals and impurities that had not yet been transformed.

It was a one-time success, and the voltage was just right.... Xu Qi'an was pleasantly surprised.

The electrolytic method produces sodium metal, and the voltage is about 6-15 volts, and he is mentally prepared for repeated failures.

I didn't expect the European Emperor to possess it, and it became one time.

Chen Fuyin and the middle-aged man couldn't wait to lean over and look, and in the cup, there was a piece of silver metal, which at first glance looked quite similar to silver.

Chen Fuyin's pupils shrank, and his heart was extremely shocked.

Li Yuchun clenched his fists hard, and looked at the silver metal block in a daze, as if lightning had struck in his mind, splitting all the fog.

"A few adults, please 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 it looks very similar, and if someone uses this thing to pass it off as silver, can it be mistaken as real? ”

He handed over the sodium metal to Chen Fuyin, and at this time, the color of the sodium metal gradually turned dull, almost exactly the same as silver.

The middle-aged man took it, checked it, his eyes sparkled, and he said continuously: "It's really a lot lighter, if it's this thing being transported, then it will be reasonable." Miss Caiwei, you try. ”

The girl in the yellow dress took it, weighed it, and then stared at Xu Qi'an with strange eyes: "You, you are an alchemist?"

No, I'm not, I'm just a chemical porter.

After Chen Fuyin was surprised, he suddenly shook his head and said in a deep voice: "No, it's not right, even if the silver is replaced like this." What happened to the explosion, if it weren't for the monsters hidden in the river, how could the fake silver explode when it entered the water. ”

Xu Qi'an didn't answer, reached out and took the sodium metal, walked to the desk, and threw it into the pen washing jar.

Blazing fires lit up and smoke billowed out.

"Boom!"

The sodium metal reacts violently in the water, and the pen washing cylinder cracks into fine cracks.

"This, this...."Chen Fuyin was stunned.

"This fake silver explodes when it encounters water, which explains why the silver explodes so violently when it falls into the water. Xu Qi'an explained.

The middle-aged man muttered: "From the very beginning, we were misled, and the mastermind behind the scenes made us think that it was a monster through explosions and demon winds, and focused the investigation on tracking and searching. ”

"It's no wonder that Qin Tianjian's Qi Gaze Technique can't observe monsters. ”

Xu Qi'an added: "After the tax silver fell into the water, the soldiers only recovered more than 1,000 taels of silver, if you guessed correctly, these silver were spread on the top layer to hide people's eyes. ”

Tightly, all anomalies are aligned.

"Xu Qi'an!" The middle-aged man's eyes were full of approval: "Okay, you're very good." ”

The brows suddenly furrowed, and froze in Xu Qi'an's crooked neckline, and Li Yuchun then patted his shoulder to help him pull his neckline neatly.

Xu Qi'an was flattered, this adult appreciated himself so much.

Chen Fuyin frowned and said, "Since the silver is fake, where is the real silver?"

When the girl in the yellow dress heard this, she also showed a solemn look: "The tax money goes out of the treasury and into Beijing, changing hands layer by layer, if you want to ask for a crime, a large number of officials will have to go to prison, and the difficulty of recovering the silver is tantamount to looking for a needle in a haystack." And this matter is beyond our competence, and we must report it to Your Majesty. ”

Chen Fuyin nodded, that's what he meant.

The middle-aged man had a different opinion, and his voice was low: "The tax silver was escorted all the way into Beijing, changing hands layer by layer, if it was fake, it should have been discovered a long time ago." The only possibility is that the package has only recently been dropped. ”

Chen Fuyin's eyes lit up, which greatly narrowed the scope of the investigation.

"Come on, prepare the sedan chair, prepare the sedan chair quickly, the official wants to travel. Chen Fuyin eagerly rushed out of the inner hall.

Middle-aged men followed.

Xu Qi'an hurriedly shouted: "Lord Fu Yin, don't forget your promise to the grass people. ”
