"It's not good, the guards of Jiaodong County are not good!"

As soon as Heifu spoke, Lu Shengbian, who was extremely vigilant, was shocked and looked at Han Zhong on the side.

Although the source of Lu Sheng and Han Zhong can be traced back to Wu Zhu in ancient times, their thoughts are mostly from Zou Yan, a yin and yang family a hundred years ago. The famous Fang Shi Song Wuji, Zheng Boqiao, Chong Shang, and Xian Men are the disciples that Zou Yan accepted when he lectured in Jieshi Palace!

But they were also divided into two major schools because of their emphasis on Zou Yan's different doctrines. The overseas immortal sect believes in the theory of "Great Kyushu", believing that in addition to Kyushu, there are three major immortal islands, on which there are Ganoderma lucidum magic medicines, waiting for people to explore.

The other school believes in the "five elements of yin and yang", believing that gold, wood, water, fire, and earth are the basic forms of all things, and the five elements are mutually reinforcing. Therefore, theoretically, stones can also be refined into gold, dansha and various rare medicinal materials, and immortal medicine can be refined......

It seems that they have learned the lesson of the chaos of the Confucian faction and the 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, so that their theories complement each other, and often help each other to cover.

But in his heart, Lu Sheng was unimpressed with Han Zhong, Hou Sheng and other alchemy pharmacists, and felt that this was an inferior technique.

Because he thinks that these things are too easy to verify the authenticity......

"The way of immortality that we use to persuade kings is often the nerve monster, the jade and the golden rope, and the one who closes the door (jiōng) in the mansion of the Ming Spirit and seals it on the altar of Yao, and ordinary people can see it."

Take the overseas immortal mountains Penglai, abbot, and Yingzhou that he advocated, only saying that they are floating on the vast sea, the smoke and waves are slim, and their faith is hard to find. Lu Sheng bragged that he had boarded it when he was young, but the fairy island was hard to find, because he ate the fairy fruit on it, so he was only seventy years old and still young, who could prove that he was lying?

In short, the alchemists must make themselves appear unfathomable, so that immortality is unattainable, and preferably never falsifiable!

As long as the skin is not unveiled for a day, they are the fairy road walking in the world, and glory and wealth are at their fingertips.

On the other hand, Han Zhong, Hou Sheng and others claim to have penetrated the subtlety of the changes in the five elements of yin and yang, so they can cause things to be immortal and get immortal medicine.

It sounds tempting, but it also makes their theories regular! has to come up with real results and hand them over to the emperor for verification, unlike Lu Sheng, who relies on imagination to make things up.

To Lu Sheng's surprise, the black man actually discovered this flaw, and he detained all the mysterious Glue Oriental Warlocks to the seashore, treated them as subordinates, and forced them to come up with a method of pouring brine in the filter with years of experience in the ancestral stove, and then released them.

Now, in front of Qin Shi Huang, Heifu asked Han Zhong what the principle was!

An inexplicable fear rose from Lu Sheng's heart: "Could it be that this black man, since a few months ago, has he been working step by step, planning to dig this big pit for our magicians?" ”

What should Han Zhong say, if he doesn't know, his so-called "knowing the changes of the five elements of yin and yang, so he can make things from the ancestral stove" has become a joke, and he doesn't even understand this simple truth, and he still has to refine the immortal medicine for the emperor to eat?

If you bite the bullet and make it clear, it's not much better.

"The god of Fangshi lies in the hidden distance of the road, the mysterious and difficult place, once it is explained, it will not be a god!" This is Lu Sheng's self-knowledge!

If he uncovered his own skin, with this precedent, who knows if Heifu will find out the root cause in the future, and ask the magician to explain how to refine gold from stones, and the principle of refining immortal medicine with dansha mercury, what should he do when the time comes?

Blame everything to the mysterious and unknown providence? Opportunity? Lu Sheng shook his head, Heifu's trick is not easy to accept!

The attack was too sudden, Lu Sheng was still in trouble, and Han Zhong was obviously not prepared, and he was also hesitating when he wanted to speak.

But before Han finally thought about the pros and cons, Heifu smiled again: "Your Majesty, it seems that Mr. Han still has to think about it, in that case, let the local warlocks who came up with this strategy talk about it." ”

Qin Shi Huang actually wanted to know the reason, so he asked Zhao Cheng to bring the three magicians who came to sue Heifu Diao.

The three magicians were also miserable by the black man, and lied to them about what "the magic trick of making strange recipes is dedicated to Your Majesty", but they turned off their skin on this seaside, and they also sent officials to scold and persecute them every day, and they didn't want to find a way to let them go. In the end, the three of them had no choice but to sacrifice their method of purifying nitrate from the brine, which was the method of drenching the brine in front of them......

After they were released, they couldn't get angry after all, and they were instigated by a small official deliberately sent by Heifu, saying that His Majesty the Emperor is a good magician, as long as he complains, he will not doubt it, and he will be evil to the guts and sue Heifu.

can look at the current situation, this Jiaodong County guard is very gentlemanly, and the three of them regretted it again, muttering that it was a misunderstanding. One of them, as if offering a treasure, boasted about the method of pouring and marinating as his "magic trick", saying that this was the recipe they dedicated to His Majesty the Emperor, and wanted to use it to invite credit.

At this time, Zhang Cang, who had already discussed with Heifu, spoke.

"Your Majesty, in fact, this is not a mystical magic at all, it is just an ordinary thing! It wasn't because the sorcerer did this, but with the help of the gods, it became effective, even if a young man came to do it, it was the same! ”

……

Everyone was shocked, and the three warlocks hurriedly argued, but Qin Shi Huang looked at Zhang Cang: "You understand? Then you can explain it. ”

Zhang Cangzuo made a move, found a tray with fresh water, took out the salt bag he was carrying, shook some white salt, sprinkled it into it, and the salt dissolved in an instant.

He grabbed another handful of salt with sand on the ground and sprinkled it into another dish, and when he added water, the white crystalline salt grains disappeared, and the silt sank to the bottom of the dish, and it was clearly visible.

Zhang Cang showed the emperor the two plates and said: "The county guard of Jiaodong told me that according to what he has seen, the common things in this world can be simply divided into two categories, those that are soluble in water and those that are insoluble in water, I deeply think so!" Soluble salt, insoluble sediment, so the sediment into the water will be concentrated, salt into the water will dissolve, but the water has a salty taste, so the salt in the water! ”

The concept of soluble and insoluble was just said to Zhang Cang by Heifu, Zhang Cang is a smart person, and he suddenly understood, alas, a scholar is a scholar.

Zhang Cang continued: "In the same way, there is salt in the sea, but when it is exposed to the scorching sun, the water dries up and the salt comes out, and it is in harmony with the mud, so there is salt in the mud. ”

"And use seawater to water the salt mud at the outlet of the filter tank, the salt in the mud dissolves when it meets water, and the mud is still insoluble. Therefore, when the filter is launched, the salt in the water is more than that of Fangcai, and it becomes brine! ”

After saying all this in one breath, Zhang Cang only felt that the brine he was caught was not a loss!

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

Zhang Cang couldn't help but think of what Heifu said to himself on the top of Mount Tai.

"People don't understand the process of change of things and only see the results, because they don't know it, so they are called 'gods', but if they find out the process of change, let people know that it is so, and remove the mysterious gauze! This is what I mean by proof, and the truth is also true! ”

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

"That's right, I proved this, according to the truth to know the truth, this is not the supernatural power of one or a few magicians, but the Great Dao of Heaven and Earth, the law of nature!"

Although the words have reached his lips, Zhang Cang has not offended Qin Shihuang's scales after the last setback.

"I see!" The five masters and children listened with straight eyes, what he couldn't figure out, was it so simple?

"That's it?"

Qin Shi Huang still had the same expression, as if he was a little disappointed that the "wonderful magic" was so boring, and with a wave of his sleeves, he asked the three "falsely accused" magicians to be detained first, and let the court lieutenant discuss their crimes.

However, Heifu interceded for the three of them, pretending that although they were full of nonsense, they promoted the implementation of the new salt law, hoping to avoid death, so that they could continue to serve the country and have a chance to atone for their sins.

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

But this group of people learned the art of yin and yang, but not to explore the composition of matter, the vastness of the world, and the principle of historical reincarnation like Zou Yan's uncle and nephew. Instead, he saw that Zou Yan was very envious of "Yin and Yang as the main luck, showing it to the princes", so he wanted to use this theory as his own skin to decorate "to immortality", and the ultimate goal was to make money and seek wealth.

Liars are not terrible, they are afraid that liars are educated, and the warlocks after changing their skins bragged about one by one, and they prospered greatly in Yanqi, deceiving King Yan Zhao and others, and in history, Qin Shihuang was also fooled by them.

As long as the purpose of the warlock is still to deceive, Heifu will continue to dig a pit for them, he is unwilling, Jiaodong, who has developed with great difficulty, will use manpower and money for useless things under the chaos of the warlock!

The episode soon ended, and Heifu continued his work as a tour guide, introducing Qin Shi Huang to the process of making new salt methods.

After the brine is made, Mr. Heff said, the salters will pull down a section of shrub called yellow croaker that grows on the seashore to determine the concentration of the brine. If the "yellow croaker" branches float on the surface of the brine, it indicates that the brine has reached a sufficient concentration to dry the salt. If the "yellow croaker" sinks to the bottom of the water or is suspended in the middle of the water, it indicates that the brine concentration is insufficient......

Qin Shi Huang nodded casually, not taking 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, he could accept and carry forward the concepts of density and buoyancy to the fat man.

But today's matter, simple soluble and insoluble can be done, why slaughter a chicken with a knife. The middle and high school knowledge in Heifu's stomach, and keep it first, and wait for Zhang Cang to digest the front, and then throw it out one by one, these things are good weapons to use against the magician.

"It's just a reminder, a warning......"

When the group left the filter, Heifu glanced at Fang Shi Lu Sheng and Han Zhong, who were embarrassed to be sent back to the palace by Qin Shi Huang after being given a cold reception. After being frustrated, their backs don't seem to be so fairy.

"If they still don't learn a lesson, they still have to jump up and down on my Jiaodong, pretending to be a ghost......"

Heifu secretly said in his heart: "I'll let them know what "Into Science" is!" ”
