Qin Official

"No, the Jiaodong County Sheriff is here with bad intentions!"

Just as Heifu spoke, Lu Shengbian, who was extremely vigilant, was startled and looked at Han Zhong who was standing aside.

Lu Sheng and Han Zhong were both alchemists. Although the origins of alchemists can be traced back to the ancient witchcraft, most of their ideas came from Zou Yan of the Yin Yang family a hundred years ago. The famous alchemists Song Wuji, Zheng Boqiao, Chong Shang, Xianmen Gao and others were the disciples Zou Yan took when he was giving lectures in Jieshi Palace!

But they also divided into two major schools because of their emphasis on Zou Yan's different theories. Overseas immortal-seeking sects believe in the theory of "Great Kyushu". They believe that beyond Kyushu, there are three major immortal islands on which there is the magical medicine Ganoderma lucidum, waiting for people to explore.

The other school believes in "Yin Yang and Five Elements" and believes that metal, wood, water, fire and earth are the basic forms of all things, and that the five elements are mutually reinforcing and interfering with each other. So in theory, stones can be refined into gold, and cinnabar and various rare medicinal materials can be refined into elixirs of death...

It seemed that they had learned the lessons of the confusion among the Confucian factions and their complete defeat in the struggle between the government and the opposition. Under Lu Sheng's plan, the three leaders of the two factions began to cooperate, allowing their theories to complement each other and often covering up for each other.

But in his heart, Lu Sheng disapproved of Han Zhong, Hou Sheng and other elixir refining and medicine makers, thinking that this was an inferior method.

Because he felt that the authenticity of these things was too easy to verify...

"The secrets of immortality that we use to persuade the king are often weird ultimatums, jade and golden ropes, which are locked (jiong) in the Mingling Mansion and sealed on the Yao Altar, so that ordinary people can't get a glimpse of them."

Take the overseas fairy mountains Penglai, Fangzhang, and Yingzhou he advocated. He only said that they were floating on the vast sea, with misty waves, and it was difficult to believe them. Lu Sheng boasted that he had been to the fairy island when he was young, but that fairy island was rare. Because he ate fairy fruits on it, he was still young at the age of seventy. Who can prove that he was lying?

In short, the alchemist must make himself appear inscrutable, make immortality elusive, and preferably never be falsified!

As long as the painting is not exposed for a day, they will be immortals walking in the world, with glory and wealth at their fingertips.

On the other hand, Han Zhong, Hou Sheng and others claimed to have understood the mysteries of the changes in yin and yang and the five elements, so they were able to worship the gods and obtain the elixir.

It sounds very tempting, but this also makes their theory lawful and followable! You also have to come up with real results and submit them to the emperor for verification, unlike Lu Sheng who just relied on his imagination to make up random things.

What surprised Lu Sheng was that the black man also discovered this flaw. He detained all the mysterious Jiaodongfang warlocks to the seaside, treated them as subordinates, and forced them to use their years of experience in cultivating things in temples to come up with the idea. The method of drenching the brine in the filter tank is used, and then they are released.

Now, in front of Qin Shihuang, Hei Fu asked Han Zhong why this was the case!

An inexplicable fear arose in Lu Sheng's heart: "Has this black man been planning to dig this big hole for our alchemists a few months ago?"

What should Han Zhong say? If Ruoyan doesn't know, his so-called "knowing the changes of yin and yang and the five elements, so he can make things happen in the temple" has become a joke. He doesn't even understand this simple truth, but he still wants to make elixir for the emperor to eat?

It wouldn't be much better if I had to make it clear.

"The god of alchemists lies in the distant and mysterious way. Once it is explained clearly, it will no longer be a god!" This is Lu Sheng's self-knowledge!

If he exposes himself, and with this precedent, who knows whether Heifu will find out the truth in the future and ask the magician to explain how to refine gold from stone, how to refine elixir from cinnabar, sand and mercury, and what will be done then?

Will everything be left to the mysterious and unknown providence? opportunity? Lu Sheng shook his head, Hei Fu's move was difficult to take!

The attack was too sudden, Lu Sheng was in trouble, and Han Zhong was obviously not prepared. He hesitated and hesitated.

But before Han finally considered the pros and cons, Hei Fu smiled again: "Your Majesty, it seems that Mr. Han still needs to think about it some more. In this case, let's let the local warlocks who came up with this strategy talk about it."

Qin Shihuang actually wanted to know the reason, so he asked Zhao Cheng to bring over the three warlocks who came to accuse the black husband of being cunning.

The three alchemists were also tricked by the black man. They lied to them about "extraordinary magic formulas and dedicate them to His Majesty." However, they ended up peeling off their skin on the beach. They also sent officials to scold and persecute them every day. They couldn't find a way to stop them. people. In the end, the three of them had no choice but to offer up their own method of purifying nitrate from brine, which was the brine drenching method in front of them...

After they were released, they were finally angry. A small official sent by a black man deliberately encouraged them a few words, saying that His Majesty the Emperor was a good alchemist. As long as he complained, he would believe it without doubt. He was like a black man.

But looking at the current situation, the Jiaodong County Sheriff was very popular with the king, so the three of them regretted it, muttering that it was a misunderstanding. One of them, as if offering a treasure, boasted about the method of soaking in brine as his "wonderful recipe", saying that this was the recipe they dedicated to His Majesty the Emperor, and wanted to take credit for it.

At this time, Zhang Cang, who had already discussed it with Hei Fu, spoke.

"Your Majesty, in fact, this is not a mysterious alchemy at all, it is just an ordinary thing! It is not because the alchemist did it and got the help of gods that it became effective. Even if a young man does it, it will be the same in this way!"

…

Everyone was shocked. The three magicians quickly argued, but Qin Shihuang looked at Zhang Cang: "Do you understand? Then you can explain."

Zhang Cang bowed, found a plate with fresh water, took out the salt bag he carried with him, shook some white salt into it, and sprinkled it into it. The salt dissolved instantly.

He grabbed a handful of salt with sediment on the ground and sprinkled it into another plate. After adding water, the white crystal salt particles disappeared, and the sediment sank to the bottom of the plate, clearly visible.

After showing the two plates to the emperor, Zhang Cang said: "The Jiaodong County Sheriff told me that according to what he saw, common things in the world can be simply divided into two categories, those that are soluble in water and those that are insoluble in water. I deeply think that Yes! The soluble one is salt, and the insoluble one is silt. Therefore, silt will gather when it enters the water, and salt will dissolve when it enters the water. However, the water already has a salty taste, so the salt is in the water!"

The concepts of soluble and insoluble were what Hei Fu had just told Zhang Cang. Zhang Cang was a smart man and he immediately realized that a top student is a top student.

Zhang Cang continued: "Similarly, there is salt in sea water. However, when exposed to the hot sun, the water dries and the salt comes out and mixes with the mud, so there is salt in the mud."

"The salt mud at the outlet of the filter was poured with seawater. The salt in the mud dissolved when it came into contact with water, but the mud remained insoluble. Therefore, when the filter was put into water, there was already more salt in the water than before, and it turned into brine!"

After saying this in one breath, Zhang Cang only felt that the mouthful of brine he had caught was well worth the drink!

In short, when seawater flows through the filter layer, the sediment remains, but the salt in the soil goes with it. This is the principle of the brine leaching method. After repeated filtration, the concentration of brine flowing out continues to increase.

Zhang Cang couldn't help but think of what Hei Fu said to him on the top of Mount Tai.

"People don't understand the changing process of things and only see the results. Because they don't understand why, they call them 'gods'. But if we find out this changing process and let people know what it is, we can take off the mysterious gauze! This This is the proof I mentioned, based on the facts to prove the authenticity!”

However, those things that seem to be contrary to common sense actually turn out to be just another kind of common sense.

"That's right, I proved this matter and used the facts to prove the authenticity. This is not the magical power of one or a few alchemists, but the great road of heaven and earth, the laws of nature!"

Although the words were already on his lips, after Zhang Cang's last setback, he stopped talking and did not offend Qin Shihuang.

"That's it!" The fifth master Ziying's eyes widened when he heard this. He couldn't understand why it was so simple?

"that's all?"

Qin Shihuang still had the same expression, as if he was a little disappointed that the "wonderful alchemy" was so boring. With a wave of his sleeve, he had the three "false accusations" of alchemists detained first, and let the court officials discuss their crimes.

On the other hand, Heifu interceded for the three of them, hypocritically saying that although they were talking nonsense, they promoted the implementation of the new salt production law, hoping to avoid death and allow them to continue serving the country and have a chance to atone for their sins.

From the perspective of later generations, the two factions of Yin and Yang alchemists are actually chemists and explorers, well, although they are wild.

But this group of people learn the art of yin and yang, but not to explore the composition of matter, the size of the world, and the principles of historical reincarnation like uncle and nephew Zou Yan. But when I saw Zou Yan's theory that "yin and yang govern the movement and manifest itself in the princes", I felt very envious, so I wanted to use this theory as my own skin to decorate "immortality", with the ultimate goal of making money and wealth.

Liars are not to be feared, but they are afraid of being educated. After changing their skins, Fang Warlock boasted all kinds of tricks and prospered in Yanqi, deceiving King Yan Zhao and others. Historically, Qin Shihuang was also deceived by them.

As long as Warlock Fang's purpose is still to deceive, Heifu will continue to dig holes for them. He is not willing to let Jiaodong, which has finally developed, use its manpower and money for useless purposes under Warlock Fang's troubles!

This episode ended quickly, and Heifu continued his work as a tour guide, introducing Qin Shihuang to the new method of making salt.

Heifu said that after the brine is prepared, the salt workers will pull off a section of a shrub called "yellow croaker" that grows on the seaside to determine the concentration of the brine. If the branches of "Yellow Fish Ci" float on the brine water, it means that the brine has reached a sufficient concentration and can be salted. If the "yellow croaker" sinks to the bottom or is suspended in the middle of the water, it means that the brine concentration is insufficient...

Qin Shihuang nodded casually and didn't take it to heart, but Zhang Cang stopped and looked at the ups and downs of Huang Yuci thoughtfully.

Heifu felt that as long as the time was right and concepts such as density and buoyancy were taught to Fatty, he would be able to accept them and carry them forward.

But today's matter can be settled simply by soluble or insoluble. Why kill a chicken with a bull's knife? Let Heifu keep the middle school and high school knowledge in his stomach for now. After Zhang Cang digests the previous knowledge, he can throw it out one by one. These things are good weapons to use against Fang Warlock.

"This is just a reminder, a warning..."

When the group of people left the filter, Hei Fu glanced at the alchemists Lu Sheng and Han Zhong who were sent back to the palace by Qin Shi Huang in embarrassment after being treated coldly. After being frustrated, their backs seemed less virtuous.

"If they still don't learn their lesson and continue to jump up and down in Jiaodong, pretending to be gods and ghosts..."

Heifu thought to himself: "I'll let them know what "Into Science" is!"
