Shengchuo's shock is not unreasonable. He is rebellious and knows very well what kind of people are those within the Mo family who really have the core secrets.

However, the middle-aged man with this pile of powder and the weird copper hook said: "Mr. I'm right, but this is not a recipe that I stole from the Mo family. I'm a alchemist, I've cracked the secret of gunpowder, and the Mo family has been lying to us! I'm a fool."

"Gunpowder only requires three substances, nitrate, charcoal, and sulfur. There is no need for salt, cinnabar, or clay..."

As soon as these words came out, everyone in the seat was shocked.

Gunpowder has been around for twenty years, but in the past twenty years, everyone in the world knows that gunpowder is made of six substances besides sulfur and charcoal.

Charcoal has already existed in the world.

Sulphur has existed in the world for a long time.

The method of raising salt has been spread all over the world, because if you want to buy gunpowder from the Mo family, you must exchange it for saltpeter.

Apart from these three, the remaining ones are all flowing out of various channels.

Everyone in the world agrees.

Although the Mohist school monopolized the production of gunpowder, it could be purchased as long as it was mined and digging canals. Gold, copper, tin, silver, grain, saltpeter, mercury, leather armor... can be replaced.

Therefore, the world does not urgently know the motivation to make gunpowder formula.

Second... Except for Si Shang, the proportion of firearms in the various vassal armies was not too high, and they were mainly used as auxiliary troops.

The man in front of me had seen Shengchuo when he was in Wei before, and it was obvious that he was Qin Jun’s confidant.

The cracking of gunpowder formula cannot be completed within one or two days. Shengchuo said in his heart: "Can you think of a way to figure out the gunpowder formula when you were in Wei State? In the past, the king was exiled in Wei and has been paying attention to the reform of Xihe... How could the king's heart be tolerated by Wei Luo?"

After everyone was surprised, Qin Jun smiled faintly and signaled the alchemist to continue speaking.

Fang Shi said, "I am a Taoist, who is good at refining elixirs. When I was in Anyi, I heard a lot about the Mo family. Later, Wu Qi defeated Daliang, and the Mo family defeated Yue people in Yanshui. The emperor asked me to try to refine them."

"Those who are the king and those who plan for the country cannot be controlled by others."

"There are not many people in the world who want to crack gunpowder techniques, but there are also many. But they are not able to do anything, so they are blinded by the Mo family."

"Twenty years ago, the lord was in Sishui and used Zhu to molten blood to kill the witch Zhu on Sishang. Since then, I have learned more about Mohist articles..."

When he said this, it was nothing for others to hear, and Shengchuo immediately understood what this person was doing.

This alchemist is the one who does dirty work by Gongzi Lian.

It is said that it is alchemy, but in fact it is also responsible for refining poisons. How can a noble conspiracy be free of poison?

Even if you don’t use poison, you should be careful of others using poison.

In the past, the incident of Zhu Zhu in Si merging blood and killing Wu Zhu had already spread all over the world. I am afraid that this alchemist had already tried to refine it. Moreover, the Mohist school did not hide the matter from that time, and even wrote down how to refine it, and called the object "phosphorus".

Shengchuo understood in his heart, but he felt that it was normal and was not surprised. He only heard the alchemist continue to say it.

"The alchemists in the world who are trying to crack the gunpowder technique are all preconceived, thinking that making gunpowder requires nearly ten kinds of drugs, and how to match them will never work."

"But I know that if you want to crack the secret recipe of the Mo family, you need to find the answer from the Mo family."

"The Mohist school has a book called "The Thirty Questions", which is said to be thirty questions asked by his two hermits before he entered the Mohist school."

"There is one thing that Mr. Tang Han asked about the right fit of the chariot one day, saying that everyone in the world knows that there are six kinds of gold. Now there is a gold that is unique and made of tin and copper, and the proportion is not known. How can we find the proportion of tin and copper when asked about the right fit of the chariot one?"

"The application of drainage and weighing method of sterilization leads to the ratio of tin and copper. This is the first question in "The Thirty Questions", and I think many people have read it."

This is true. Many people have seen more than just seen it. The thirty stories in it are not true or false, but they are carefully arranged. The purpose is to allow people to understand the summary, summary, and find the method of knowing the rules through a series of stories after reading it.

The alchemist smiled and said, "That day I suddenly thought of this story, and then I thought of another thing."

"The various raw materials used for refining can actually be separated."

"Charcoal, cinnabar, clay, sulfur, insoluble in water."

"Saltpe, salt, and Glauber's salt are all dissolved in water."

"Those that are insoluble in water can be divided into carbon floating in water, and sulfur sinking in water."

"Since there are nearly ten substances in the formula of gunpowder, why don't I separate these ten substances? Only a few of them dissolve in water, so there are many fewer ones, so it can be easier to eject proportions; there are two types of them floating on the water surface, so it can also be easier to eject proportions..."

Speaking of this, Shengchuo, the rebellious Mo, had already become enlightened, and couldn't help but clap his hands and praise him: "Miscellaneous! Great! Simplify the complex and find out the rules. This is the reason for the seventeenth question in "The 30 Questions"."

The alchemist smiled and nodded, and said, "So I took a hundred kilograms of gunpowder from you and dissolved it in water. When it settles and floats, it will no longer be turbid, then take the solution first."

Shengchuo nodded. Saltpeter is indeed the key. If saltpeter is not the key, why did the Mohist school pass on the method of raising salt to the world?

Because there is not enough saltpeter in Si Shang, people all over the world have to help them raise saltpeter, and they use saltpeter to make gunpowder and then sell it with excess profits.

How to compare saltpeter, salt, and Glauber's salt, is really the key.

The alchemist said in a deep voice: "Take a certain amount of jar and put the same saltpeter, salt, and Glauber's salt. After I weighed it, I found that their weight was different. This is the first question in "The 30 Questions", the method of Six Universal."

"I found that saltpeter is the lightest, salt is the second, and Glauber's salt is the heaviest. The ratio is seventy-eight, eighty-one, and one hundred."

"In this way, then this question will be simple. You have also learned nine numbers and have the problem of finding the grain in equations, just like that."

"Now there are three upper grains, two middle grains, one lower grain, and one lower grain, and thirty-nine dou; two upper grains, three middle grains, and one lower grain, and thirty-four dou; one upper grain, two middle grains, and three lower grains, and thirty-six dou. What is the same as the upper grain, and one lower grain, and thirty-six dou. "

When Shengchuo heard this, he clapped his hands and praised: "Miaoji! Miaoji! This is a three-element equation. You only need to measure the weight of the saltpeter you precipitated from the dissolved water of gunpowder to know the amount of saltpeter, salt and Glauber's salt!"

At this point, everyone present already understood that the most mysterious ratio of saltpeter, salt and Glauber's salt, can be known.

Glauber's salt absorbs water. Those who have truly studied gunpowder know that this is also a major factor that the gunpowder they match is always inferior to Si Shang gunpowder, especially the remaining residue is very large, and the crystal water absorbed by Glauber's salt will also make the gunpowder collapse quickly.

The few people present are proficient in alchemy methods, but when it comes to nine numbers, they are one of the six arts of gentlemen. Since they are gentlemen, who can't calculate a three-element system of equations?

At this point, it is already a problem with Shanghe, Zhonghe and Xiahe among the nine common cases.

The alchemist was silent for a moment and said, "But after I measured the weight, I found a problem. If gunpowder really had salt, Glauber's salt and saltpeter, then this three-element equation would have no solution."

"Because the amount of salt and Glauber's salt I calculated is negative. Negative can exist in the nine numbers, but cannot exist in the reality of the world."

"Unless... there is no Glauber's salt or salt in it, this is possible."

"As the saying goes, nine numbers and geometric Pythagoreans will not deceive people."

"Then at this point, there are only two possibilities left."

"Or, nine numbers can be deceptive."

"Or... it's the Mohist family who is cheating - there is no salt or Glauber's salt in gunpowder! There is only saltpeter!"

Everyone present was shocked by the use of this method.

No one suspects that Glauber's salt does not contain in gunpowder, because the Mohist family wants too much, and this thing seems to be useless at all.

There are many salt-alkali ponds in Glauber's salt. The Mohist "Tianzhijie of Steaming and Cooking and Eliminating Salt" introduces the relationship between temperature and solubility, and explains how to cook various kinds of nitro, salt, alkali, etc.

They did not know that the Glauber's salt, which seemed to be transported into gunpowder workshops, was actually used in the production of bast paper, purlin, porcelain glaze and other industries.

This is a big scam. There are not many people who originally thought about what gunpowder is, and among the few people who think about it, there are people who need to consider the hearts of the people: Glauber's salt is useless, why does the Mohist family spend money to acquire it from other places? Unless it is a formula for gunpowder.

The alchemist had no doubt at first. He just thought of the problem of "grain produces rice", divided the complex raw materials into water-soluble and insoluble, and then used the three-element equation among the nine numbers to solve the answer.

But he calculated two negative numbers, which was obviously wrong.

If you believe that Nine Numbers will not deceive people, then the Mohist family is cheating people, and there is no salt or Glauber's salt in the gunpowder.

When he arrived here, Shengchuo no longer doubted the authenticity of the pile of gunpowder. He was sure that the alchemist had obtained the correct formula of gunpowder.

Sure enough, the alchemist continued, "I was just suspicious at that time. Then I took the things that were sinking under the water."

"Cinsha... we are naturally familiar with the alchemists. Sulfur can combustible, and cinnabar can refine mercury. Everyone knows it. I first assumed that there was cinnabar inside, but the result was that I didn't refine mercury at all."

"The "Story of Heavy Qi" written by the Mohist School says that things already existed when Emperor Tian created the world and Fuxi opened the sky, and it is impossible not to be less. So, since there is no mercury, that is, there is no cinnabar in those."

"I took some more and just lit it. The clay cannot burn. If there is clay inside, it is obviously impossible to burn it all. So I know that there is clay inside either."

"At this point, I am convinced that the Mo family has been cheating on the princes. So I spent a year looking for many disciples and servants to find one thing from all the books of the Mo family... Did the Mo family say in person that gunpowder must require those nine substances?"

"However, no. The Mohist family does not lie, this is their righteousness."

"But in some things, they will tell some truth. From the beginning to the end, the Mohist family did not clearly say that gunpowder is a combination of nine things, but only some rumors and speculations based on the raw materials transported to the workshop by the Mohist family."

"So I guess, this gunpowder...is not that complicated at all."
