Chen Mao looked embarrassed on his face, but he didn't expect Yang Chengxing to guess it, and couldn't help but scold himself, "Am I so good at acting?" ”

"Uh..."After Chen Maosan calmed down for a while, he said with a smile, "Brother Chengxing really has good eyesight, that's right, I came today for yesterday's things." ”

"Oh? I wonder what His Highness said? Yang Chenxing suddenly became interested.

"His Royal Highness asked the four of us to go to negotiate together, and he said that he didn't like someone behind him to make small moves..."Chen Maosan said and wiped his nose.

Yang Chengxing hesitated for a moment, thought for a moment and asked, "Then I don't know, Third Brother Mao, what is your Chen family's plan?" ”

"Brother Chengxing, I won't just call you haha, coming to the door today, not only to convey the meaning of His Highness, but more importantly, I think our Chen family and your Yang family can completely join forces to win the management right of this glass bottle, when the Su family and the He family are not far behind us, you also know that in the past two years, our Chen family's business has become more and more difficult to do, but the business of the Su and He families has become more and more prosperous, and the first and second positions of you and I are not guaranteed!" Chen Maosan said bitterly.

The four major families have always been the Chen family in the first place, the Yang family is second, the Su family, and the He family occupy the third and fourth positions respectively, but in the past two years, with the continuous border friction, the Chen family's border trade business has been seriously affected, and the Yang family has always been proud of the dart business all over the world.

On the contrary, the Su He family has been developing steadily by relying on iron ore and coal mines respectively, and even with the current situation, there are signs of surpassing the Yang family, so Chen Qingshan was worried that the two families would threaten his Chen family's status, so he organized the four major families to negotiate, but the Su He family was not interested at all, so in fact, Chen Maosan was sent to fight the autumn breeze as soon as the Chen and Yang families discussed.

But because of the alliance of several major families, so the other two Chen Qingshan symbolically sent a small servant to inform the meeting, Li Zhi asked them to send people to negotiate the results, in fact, Chen Qingshan originally didn't want to inform these families, and it would be good for the Chen family to take it alone, but after thinking about it, he felt that it was inappropriate, in case His Royal Highness would pursue it later, he could not afford this responsibility, and he would not steal the chicken and rice at that time.

After Yang Chenxing digested it a little, Chen Maosan leaned into Yang Chengxing's ear and whispered, "I heard from the grapevine, now the Foundry Bureau has set up a new glass workshop for that thing, and those transparent things are piled up all over the warehouse, if it weren't for the guards to watch it carefully, now one or two things can be made on the market, I heard that the thing on the black market has been fried more expensive than the glaze." After speaking, he was full of sighs.

Yang Chenxing's face was stunned after hearing this, he didn't expect this glass bottle to be so hot, and he couldn't help but feel moved in his heart, so he said, "I don't know what the third brother Mao has planned?" ”

"Listen to me... We are so.. This way.." Chen Maosan leaned over and said softly.

After a while, Yang Chengxing listened, and couldn't stop smiling on his face, "Third Brother Mao, if it is really as you said, then my Yang family will definitely support it unconditionally, and we will definitely work together to win the right to operate this glass bottle, haha!" ”

But Chen Maosan said with some hesitation; "But I don't know if it's a big deal, can Brother Chengxing take the place of Uncle Yang and have full authority to make the decisions?"

Yang Chengxing was slightly displeased, waved his hand and said: "Third brother Mao, just rest assured, my father recently took my eldest brother to Haizhejiang Province to be busy with the affairs of Qianzhuang, and before leaving, he specially instructed me that all things in the family should be handled by me." ”

"That's good, Brother Chengxing forgive me, it's not that I don't believe you, it's not trivial at this time, I still have to be careful, after all, this matter is related to the huge interests of our two families."

"Understand, understand, Brother Mao, the matter has been negotiated, as I just said, I will stay today, I have ordered someone to prepare a banquet, today hehe... If you don't get drunk, you won't return..."Yang Chengxing showed a smile that all men understand.

The two of them are raccoon dogs, the smell is similar, and you can still feel the scene of the song and swallow dance in the Yang Mansion in the middle of the night......

Another day passed......

Shin Wangfu...

Since Chen Maosan went back the day before yesterday, Li Zhi and Zhang Qing were tired of saying goodbye for a night, and the next day Li Zhi began to write in the study with a pen in the booklet that later generations of science students memorized backwards - the periodic table.

This is the most basic thing for the development of chemistry in the future, a few days of preparation, the glass laboratory equipment required for the chemical laboratory has been blown out, and the difference from the general chemical laboratory in later generations may be that there are no precision instruments and alcohol lamps.

In ancient times, there was no high number of wines, all of them were koji fermented wines, and the degree was relatively low, generally about 8 to 10 degrees, and the refined wine was only 20 degrees.

Let's just say that Wu Song's three bowls in "Water Margin" are not good. The restaurant said: "Although my family's wine is village wine, it tastes better than old wine; But if a customer comes to my shop and eats three bowls, he gets drunk and can't go to the hill in front of him: hence the name 'three bowls but not Gang'.

Therefore, at that time, it was very likely that in the era of common eight to ten degrees of wine, and the restaurant mastered a certain method to make wine with a high number of degrees, it may not be forty or fifty degrees, but it must be higher than the ordinary water wine, otherwise just those three bowls of water wine, let alone Wu Song, even ordinary people can't get drunk.

Therefore, Li Zhi still criticizes the wine of this era a lot, although Li Zhi does not drink, but as a chemical alcohol lamp, the alcohol content of this era is far from enough to ignite.

Generally speaking, 50 degree liquor can only be burned when the ambient temperature is higher than 20 degrees. A liquor of 40 degrees can only be ignited when the ambient temperature exceeds 30 degrees.

Therefore, if Li Zhi wants to complete the establishment of the chemical laboratory, the next step is to purify alcohol from wine, that is, ethanol.

However, purification requires the use of a distiller, which was actually used in ancient China, but was generally used in alchemy, such as the practice of sand smelting mercury. Mercury refining was first made by a simple low-temperature oxidation roasting method, and it was only developed into a closed mercury extraction method in the Eastern Han Dynasty, that is, the container was sealed and then heated, and the mercury vapor decomposed by Dansha was condensed on the inner wall of the container. This kind of mercury refining equipment, together with a condensing device and a mercury collector, constitutes a relatively primitive still, but the material is generally made of wood or copper, the wooden one is easy to breed bacteria, and the quality is affected after a long time, and the copper one is not easy to make, and the cost is high.

And now for the material of the still, Li Zhi has a lot of choices, the most basic wooden still, ceramic still, copper still, iron still can be made, the process is not limited to completely hammer forging, the secret research of the lathe in the workshop of the Foundry Bureau has produced several sets, in addition to using it to produce iron blowpipes for blowing glass, has not participated in large-scale projects, because the durability of its drill bit is too low, the cost of producing other things is too high, but fortunately, with the birth of the lathe, The flintlock pistol had the conditions for production, so Li Zhi had secretly arranged for Li Qing to start trying to drill the barrel with a lathe and a drilling machine two days ago, but now I don't know what the result is.

Because the technical content involved in the manufacture of the barrel is not low, the craftsmen of the steelmaking workshop and the forging workshop of the seamless steel pipe have jointly researched it, and now there is a little frown, but the steel pipe produced is still somewhat unsatisfactory and is being improved again and again.

Li Zhi, the important core of its flintlock pistol, was also handed over to Zhao Jiujiang to be responsible, and the important task of spring steel research was handed over to Liu Hai, the person in charge of the steelmaking workshop, and Li Zhi personally ordered him to be responsible for the research, and even the formula of the slag cleaner Li Zhi was handed over to him, so that he was responsible for improving and making sure to study the spring steel.

At this point, Li Zhi has completed the layout of the flintlock pistol, and the entire casting bureau has been kept airtight, and the eyes and ears of the four major families, Li Zhi has already sent someone to find out, but they are just secretly monitoring, because they have no access to these secret projects at all.

The periodic table was soon written, put aside, and then picked it up again and began to sketch something with a brush...
