The Triple Alliance, the Great Liang Dayu. The wine and meat in the treasury were brought out and distributed to the common people in the city and the Zhao people who had just moved here. After the wine and meat are distributed, the money will be paid directly, one silver coin per person. Daliang is close to the war zone, and the price of grain in the city has risen to 80 yuan because of the city tax, and a silver coin is worth about half a stone millet, and half a stone millet is nearly nine catties of rice, and the poor can eat for half a month.

The next day, the Dachu news praised the grandeur of last night's feast, especially mentioning the ceremonial poems at the banquet. The King of Wei sang "Chang Di", the King of Zhao responded to "Ben", the State of Chu sent troops to rescue Zhao and moved south to the Zhao people, so Wei Zhao Qi sang the King of Chu's "Fake Music", and the King of Chu wanted to return the gift with "Yuli", but in the end, he sang another poem:

"When you sing about wine, life is geometric. For example, the morning dew is bitter in the past. Be generous and unforgettable. How to solve the problem? Only feathers. Xiao Xiao Ma Ming, leisurely my heart. But for the sake of the king, he has been chanting to this day......"

Cao Cao's "Short Song Xing" has been tampered with some words, the poem originally asked for 'Qingqing Zijin', Xiong Jing should not be the official's 'Qingqing Zijin', he just needs to charge into battle 'Xiao Xiao Ma Ming'.

"Tanka Xing" has been passed down through the ages, not only because it was written by Cao Cao. The Jian'an period of the Eastern Han Dynasty was also a period of collapse of etiquette, endless wars, and displacement of the people, and the situation was even worse than at the end of the Warring States Period. The poems and articles produced in this period are naturally strong and deep, generous and sad in style, so they are called Jian'an style bones.

The Eastern and Western Han Dynasty are directly inherited from the Warring States Period, "Tanka Xing" is ancient and sad, its rhythmic artistic conception is completely in line with the present, and the music of the graceful and luxurious "Yuli" is accompanied by a short song line, and it also sings a bit of Jian'an style.

Since the poem "Ten Thousand Miles to the Rong Machine", the king of Chu knows how to compose poems. What the world doesn't know is that he is not composing poetry, he is reciting poetry. When I was a child, I had to memorize ancient poems, and Xiong Jing remembered it well. As soon as "Short Song Xing" came out, Da Chu News was printed the next day, but it was still sold out early in the morning, and Gongsun Yan's maidservant paid a high price, so she bought a copy from the restaurant.

"The King of Chu was in Daliang last night." The maidservant said, pointing to the front-page article in the newspaper. After running around for a few months, I finally met.

"Singing about wine, what is life? For example, morning dew, the days are bitter and ......" Gongsun Yan did not answer, her eyes stared at the newspaper motionlessly, reading this song "Song to Wine".

The closer to the Central Plains, the more scholars, although poetry is not the main theme of this era, the king of Chu asked for a warrior rather than a civil servant, but such a strong and sad poem is still easy to arouse the resonance of scholars. After reading the whole poem, Gongsun Yan also held the newspaper and was silent for a long time.

"Why is the son-in-law and son-in-law crying?" The maidservant looked at Gongsun Yan in surprise.

"How can I cry?" Gongsun Yan wiped her eyes, "It's just dust." ”

It costs a lot to take a boat to Daliang, and the rest of the money can only live in a simple reverse trip outside the city, which is still the lowest layer. As soon as someone walks around on it, dust falls through the cracks in the planks. Gongsun Yan was covering up, she thought that the King of Chu was just a barbarian king who liked to kill, but in fact the King of Chu was a great king like Qi Huan and Jinwen, protecting China from being swallowed by Rong Zhai Qin. And he is different from Qi Huan Jinwen in that he can compose poems, thinking that if he can accompany the king of Chu for a long time, Gongsun Yan cried excitedly.

"Bath, I want to change my clothes." After wiping away her tears, Gongsun Yan instructed her to put on the most beautiful clothes to meet Xiong Jing.

"Who should be sent to Qin?" The king of Wei left Zhao Qian and Lingyuan to live in the southern city of Daliang, and Xiong Jing returned to the northern city of Daliang. Taking advantage of his leisure, he was already arranging the redemption of Mi Ling. Artillery can be given, but given to the monkey version that exists in question.

"The minister thought that he should send Wei people to Qin." Zhuang Wudi, Nao Xin, and Zuo Shi are Wang Tinglu, not ministers of Sheji, but Xiong Jing's private ministers. Nao Xin's proposal of exchanging cannons for people is very constructive, especially this method can exchange for his brother's broken bones, his family members who were punished as ghost salaries, and those captured spies of the Marquis of Chu, which made Xiong Jing determined to complete this matter.

"Wei people?!" Xiong Jing was surprised. He thought it would be one of Zhuang Wudi and Naoxin.

"Yes, yes." From the time he heard about this, Zhuang Wudi never thought of using Chu people. "The minister heard that the king of Qin hated my Chu people deeply, and followed Goujian every day, and the temple people asked him if he had forgotten the humiliation of the Jing people. Only the Wei people can make Qin meet the king of Qin and talk about this matter. ”

"Humiliation of the Jing people......" Xiong Jing knew about this, and his expression became grim under his smile.

"King Qin doesn't miss my benevolence, he is only ashamed and hates me deeply." Zhuang Wudi said helplessly. He regretted a little that he only killed the left toes of those Qin army soldiers at that time, and did not kill all of them. "In this matter, we should choose a Wei person, who will make Chu, who will transport the artillery to Qin, and who will also transport Changping Jun, the king's uncle, Changping Jun's dependents, and our Hou spy to Daliang."

"However, the king of Qin will get my artillery, or use it in Hanzhong, this ......" The Wei people made Qin, presiding over this transaction, Nao Xin completely agreed, but he was worried about the leakage. Artillery is a weapon, and weapons will always be on the battlefield.

"Tell Ruo Ao to be on guard." Zhuang is not authentic. "Or give it an artillery battalion, if the Ao clan will be happy."

Gunpowder was insufficient, and all divisions were helped in equipping them with artillery. If an artillery battalion is delivered to the Ruo Ao clan in advance, the generals of the Ruo Ao clan will not only not complain, but will also be happy. This is the first division of the Zhu clan to be equipped with artillery outside of the Ying Division.

"But I don't know what the monkey version of the cannon the king said?" Zhuang Wudi is not worried about the leakage of the incident, and is worried about the actual lethality of the artillery.

"Man is a man, a monkey is a monkey, and the monkey version is used by apes." Xiong Jing was silent for a while before he said. "Even if the monkey version is not used, the Qin people don't know the essence of artillery, and they can't use it. A well-trained cannon can completely suppress an untrained cannon pawn. The cannon is made in three years, and it is ripe in three years, and there is a reason for it. And the use of artillery is all in gunpowder, if there is no gunpowder, what is the difference between artillery and evil iron? ”

Xiong Jing hadn't figured out what kind of monkey version to give to the Qin people, in fact, he gave it the genuine version, and the Qin army, who didn't understand the principle of ballistic parabola, would only bombard it indiscriminately. But Zhuang Wudi had the same worries as Li He, and he said: "Since the weight of artillery is all in gunpowder, if gunpowder is imitated by the Qin people?" So how? ”

"It's impossible." Xiong Jing shook his head without even thinking about it. "The system of gunpowder, even if the Qin people know what it is made of, they cannot imitate it. Recrystallization ......"

Speaking of this, Xiong Jing didn't want to say any more. Zhuang Wudi is not a technician, he doesn't understand technology, and it's useless to say. The key to gunpowder is the purification of nitrate. I have been researching and experimenting on nitrate for several years, but it is still spinning on recrystallization, and it is impossible to completely remove the nitrate salt in the nitrate.

In fact, there are a lot of impurities in nitrate, for example, the residue accounts for 81.33%, calcium carbonate accounts for 12.12%, magnesium sulfate accounts for 0.56%, calcium sulfate accounts for 0.66%, sodium chloride accounts for 1.97%, sodium sulfate accounts for 0.56%, magnesium nitrate accounts for 0.85%, and the active ingredient potassium nitrate accounts for only 1.72% [Note 15].

Among them, calcium carbonate is basically insoluble in water, so the percentage of the remaining substances after dissolution is: magnesium sulfate accounts for 8.54%, calcium sulfate accounts for 10%, sodium chloride accounts for 30.07%, sodium sulfate accounts for 8.54%, magnesium nitrate accounts for 12.97%, and the active ingredient potassium nitrate accounts for 26.25%.

When the solution is cooled and crystallized, the solubility of magnesium sulfate is about 50 grams at 100 degrees, the solubility is 33 grams at 20 degrees, and the precipitation is 17 grams; Although the solubility of calcium sulfate is greater than that of calcium carbonate, the solubility is the largest at 40 degrees, but it is only 0.211 grams, which is negligible; The solubility of sodium chloride is 39 grams at 100 degrees, 36 grams at 20 degrees, and only 3 grams are precipitated; The solubility of sodium sulfate is 42 grams when it is 100 degrees, 19 grams when it is 20 degrees, and it is precipitated 23 grams;

Seventeen grams of magnesium sulfate, three grams of sodium chloride, and twenty-three grams of sodium sulfate, so that there are forty-three grams in total. However, the sum of the three is not as much as the precipitation of magnesium nitrate, and the solubility of magnesium nitrate is about 150 grams at 100 degrees [Note 16], and 73 grams at 20 degrees, and the precipitation is as much as 77 grams. The solubility of potassium nitrate changed the most, and the solution could be precipitated from 100 degrees to 20 degrees, and 215 grams could be precipitated.

In terms of percentage, magnesium sulfate accounted for 5.07%, sodium chloride accounted for 0.89%, sodium sulfate accounted for 6.86%, magnesium nitrate accounted for 22.98%, and the active ingredient potassium nitrate accounted for only 64.17%.

This is true for primary crystallization, and this is basically the ratio for recrystallization. If magnesium nitrate cannot be removed chemically, the power of gunpowder cannot be increased at all. The methods used to remove magnesium nitrate from modern Western black powder are all derived from the book "Equestrian and War Strategy" written in 1285, written by Hansan Rama Najim-al-Din Ahdab, born in Syria under the Ilkhanate, in 1256, in the Mongol servant army, assisting the Mongols in administering the Arabs.

If magnesium nitrate can be removed, the proportion of potassium nitrate will theoretically rise to 83.33%, but in the actual chemical reaction, magnesium sulfate accounting for 5.07% and sodium sulfate accounting for 6.86% will also participate in the reaction to form precipitated substances that are difficult to dissolve in water, and the result is that the potassium nitrate content reaches an astonishing 97%, or higher.

This is the fundamental reason why the gunpowder of the Qing army is inferior to the gunpowder of the British army, and it is also the fundamental reason why the gunpowder of the mansion must be charged four times.

Although the Ming Dynasty's "Armed Equipment" mentioned that it was necessary to add substances that eliminated nitrate sulfate, it was obviously castrated data, compared with adding radish and egg white, it was like stir-frying vegetables and chicken essence, and the extremely rare dosage was the same as not adding. Nitrates and sulfates could not be eliminated at all, and as a result, more than one-third of the impurities in the nitrate were present, and if the recrystallization process was missing, the impurities would likely be close to half.

Xiong Jing believes that even if they tell the Qin people the raw materials and formulas of gunpowder, they do not know how to use the crystallization method to purify, which after all, requires the support of chemical theory and cannot be achieved overnight; Even if they did crystallize and purify, what they produced would be inferior gunpowder with a quadruple charge.

He could no longer stand this inferior gunpowder, because it would waste three times as much sulfur. While Red Mou went to Wublay Harbor in the Persian Gulf to teach the Seleucids, Red Mou led a fleet to the Americas in search of Chilean saltpeter in the Atacama Desert in Chile.
