Shengxuan's shock is not unreasonable, he is a rebel against Mo, and he knows too well what kind of people are those who really master the core secrets within the Mo family.

However, the middle-aged man with this pile of powder and the strange copper hook said, "What Mr. said is right, but this is not a recipe stolen from the Mo family. I'm Fangshi, I have cracked the secret of gunpowder, and the Mo family has been lying to us! Lie to the world. ”

"Gunpowder only needs three things, nitrate, charcoal, and sulfur. There is no need for salt, dansha, clay ......"

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

Gunpowder has been around for 20 years, but in the past 20 years, the world knows that gunpowder is made of six substances in addition to sulfur and nitrocarbon.

Charcoal has been around for a long time.

Sulfur has long existed in the world.

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

In addition to these three, the remaining ones are all flowing out of various channels.

The whole world thinks so.

Although the Mo family monopolized the production of gunpowder, as long as it was used for mining and digging canals, it could be purchased. Gold, and brass, and tin, and silver, and grain, and saltpeter, and mercury, and leather armor...... All kinds of things can be changed.

Therefore, there is no motivation to know the formula of gunpowder urgently.

The second ...... With the exception of Sishang, the proportion of firearms in the armies of the princes was not too high, and they were mainly used as auxiliary troops.

The person in front of him had seen it before when he was in the Wei Kingdom, and it was obvious that this was Qin Jun's henchman.

The cracking of the gunpowder formula cannot be completed in a day or two, Sheng Xuan secretly said in his heart: "Could it be that when you were in the Wei Kingdom, you were already thinking of a way to figure out the gunpowder formula?" Also, in the past, the monarch was in exile in Wei and had always paid attention to the change of law in Xihe...... The heart of the king, is it just a little Wei Luo can be tolerant? ”

After everyone was surprised at this time, Qin Jun smiled faintly and motioned for the priest to continue.

Fang Shi said: "I am a Fang Shi, good alchemy." When I was in Anyi, I heard a lot about the Mo family. After Wu Qi broke the beam, and the Mo family defeated the Yue people in the water, the king asked me to try refining. ”

"Those who are kings and those who seek the country must not be controlled by others."

"There are not many people in the world who want to crack the art of gunpowder, but there are many of them, but they are all lawless, so that they are deceived by the Mo family."

"Twenty years ago, he was in Surabaya and poisoned Sishang Wuzhu with Zhu Rongxue. Since then, I have studied more Mohist articles......"

When he said this, others listened to it nothing, and Sheng Xuan suddenly understood what this person was doing.

This alchemist is doing dirty work around Gongzilian.

said that it was alchemy, but in fact it was also responsible for refining poison, and the aristocratic conspiracy, how could it be non-toxic?

Even if you don't use drugs, you should be careful not to use them by others.

In the past, the matter of Si Shangzhu melting blood and poisoning Wu Zhu had already spread all over the world, I am afraid that this Fang Shi had already tried to refine, and the Mo family did not shy away from the things of that year, and even wrote out how to refine it, and called that thing "phosphorus".

Sheng Xuan understood in his heart, but he also felt normal, and he was not surprised, so he just listened to the Fang Shi continue.

"Those Fangshi and Danshi in the world who try to crack the art of gunpowder are all preconceived, thinking that to make gunpowder is to need nearly ten kinds of drugs, and how to mix them is always not good."

"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 Mo family has a book called "Thirty Questions to Solve Questions", which is said to be the thirty questions asked by his two hermit masters to test his intelligence when he did not enter the Mo family."

"There is one thing, it is said that one day Mr. Tang Han asked the suitability of the art, saying that everyone in the world knows that there are six Qi in gold. Now there is a gold, different, made of tin and copper, and its proportion is unknown. Ask how to find out the ratio of tin-copper. ”

"The method of drainage and weighing is applied to the art, and the ratio of tin and copper is obtained. This is the first question of "Thirty Questions to Solve", and many people have seen it. ”

This is true, many people have seen it. The thirty stories in it, I don't know whether they are true or false, but they are all carefully arranged, the purpose is to let people understand the way of summarizing, inducting, and finding the law of "knowing why it is true" through a series of stories after reading it.

The priest smiled: "That day I suddenly thought of this story, and then I thought of another thing. ”

"In fact, all kinds of raw materials used in refining can be separated."

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

"Saltpeter, salt, and miscanthus are all soluble in water."

"And those that are insoluble in water can be divided into charcoal floating in water, sulfur and so on sinking in water."

"Since there are nearly ten substances in the formula of gunpowder, why don't I separate them? There are only a few that are soluble in water, so there are many less, and it is easier to push out the proportions; There are two kinds of floating on the water, and it is easy to push out the proportional ......"

Speaking of this, Shengqiu, a rebel who had already become enlightened, couldn't help but clap his hands and praise: "Wonderful! Wonderful! Simplifying the complex and finding out the rules is exactly the principle of the seventeenth question in "Solving the Thirty Questions". ”

The Fang Shi nodded with a smile, and said, "So I took a hundred catties of gunpowder from the king, dissolved it in water, and when it precipitated and floated and was no longer turbid, I took the solution first." ”

Sheng Xuan nodded, saltpeter is indeed the key, if saltpeter is not the key, why does the Mo family want to spread the method of raising nitrate to the world?

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

Saltpeter, salt, and miscanthus salt, how to mix these three is really a key.

The priest said in a deep voice: "Take a certain amount of jars, and hold the same saltpeter, salt, and miscanthus salt, and after I weigh them, I find that their weights are not the same. This is the first question in the "Thirty Questions to Explain", the method of the Six Qi. ”

"After weighing many times, I found that saltpeter is the lightest, followed by salt, and miscanthus is the heaviest. And the proportions are seventy-eight, eighty-one, one hundred. ”

In this case, then the problem is simple. You've all learned nine numbers, and you have the problem of finding the equation, and that's the same. ”

"Today there are three Bing on He, two Bing on He, one Bing on Xia He, and thirty-nine buckets in reality; Shanghe two bing, middle he three bing, xia he one bing, real thirty-four buckets; Shanghe one bing, middle He two bing, Xia He three bing, real twenty-six buckets. Q: Upper, middle and lower Heshi are each geometric? ”

When Sheng Xuan heard this, he clapped his hands and praised: "Wonderful! Wonderful! It's a ternary equation that just measures the weight of the saltpeter that you precipitate from the gunpowder dissolved water to know the amount of saltpeter, salt, and miscanthus! ”

At this point, everyone present already understood that the most mysterious ratio of saltpeter, salt and miscanthus in gunpowder could be known.

Miscanthus nitrate absorbs water, and those who have really studied gunpowder all over the world know that this is also a major factor that their ratio of gunpowder is always inferior to the power of gunpowder in Sishang, especially the remaining residue is very much, and the crystal water of miscanthus nitrate absorption will also make gunpowder quickly solidify.

Few of the people present are proficient in the methods of the Fangshi, but when it comes to nine numbers, it is one of the six arts of a gentleman.

At this point, it is already a problem of Shanghe, Zhonghe, and Xiahe in the nine-number norms.

Fang Shi was silent for a moment and said, "But after I weighed it, I found a problem. If gunpowder really has salt, miscanthus and saltpeter, then this ternary equation is unsolvable. ”

"Because the amount of salt and miscanthus I counted was negative. Negative can exist in the number nine, but it cannot exist in the reality of the world. ”

"Unless...... There's no salt, there's no salt, that's possible. ”

"As the Mohists often say, nine numbers and geometric Pythagorean do not deceive."

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

"Or, the number nine can be deceived."

"Or...... It's the Mo family who is deceiving people - in gunpowder, there is no salt at all, and there is no salt! Only saltpeter! ”

Everyone present was shocked by the use of this method.

No one doubted that the gunpowder did not contain miscanthus salt, because the Mo family wanted too much, and this thing seemed to be useless at all.

The relationship between temperature and solubility was introduced in the Mohists' "Celestial Interpretation of Cooking and Salt Separation", and explained how to cook out various nitrates, salts, alkalis, etc.

They didn't know that the miscanthus that seemed to be brought into the gunpowder workshop was actually used in the production of bast paper, xuanlin, porcelain enamel and other industries.

This is a big scam, there are not many people who think about what the gunpowder is all about, and there are not many people who think about it to consider people's hearts: manganese is useless, why should the Mo family spend money to buy it from elsewhere? Unless it's a recipe for gunpowder.

Fang Shi didn't doubt it at first, he just thought of the problem of "Hehua out of rice", divided the complicated raw materials into water-soluble and insoluble, and then used the three-element equation in the nine numbers to solve the answer.

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

If you believe that the nine numbers will not deceive people, then the Mo family is deceiving people, and there is no salt and miscanthus in the gunpowder at all.

By this point, Katsu had no doubts about the authenticity of the pile of gunpowder, and he was sure that the alchemist had come up with the correct recipe for the gunpowder.

Sure enough, the alchemist continued, "At that time, I was only suspicious. Then I took the gunpowder that had sunk underwater. ”

"Dansha...... We are naturally familiar with it. Sulfur is combustible, and dansha can be used to refine mercury, which is well known to all monks. I first assumed that there was actually dansha in it, but as a result, I didn't refine any mercury at all. ”

In the Mohist book "Qi is also Heavy Sayings", it is said that things have existed since the creation of the Emperor of Heaven and the opening of the heavens by Fuxi, and they cannot be more or less. Well, since there is no mercury, that is, there is no dansa in those at all. ”

"I took some more and just lit it. Clay can't be burned, and if there's clay in it, it's obviously impossible to burn it all clean. So I know, there is no clay in it either. ”

"At this point, I am already convinced that the Mo family has been deceiving the princes. So I spent a year looking for many disciples and attendants, and together I found something from all the books of the Mo family...... Did the Mo family personally say that gunpowder must need those nine substances? ”

However, no. The Mohists don't lie, this is their righteousness. ”

"But there are things where they tell part of the truth. From beginning to end, the Mo family did not explicitly say that gunpowder was a combination of nine substances, but only some rumors and speculations based on the raw materials that the Mo family transported to the workshop. ”

"So I guess this gunpowder ...... I'm afraid it's not that complicated at all. ”

"It's simple and reasonable."
