[There are two more shifts in the night.] One shift should be in the middle of the night, and then the next one please see tomorrow morning. Then continue to ask for a monthly pass, there are only twenty-seven hours left before the end of the month, whether you can hold the tenth position, just look at the last twenty-seven hours. If you still have a commuter pass, please don't hesitate any longer.

On the second watch, Han Gang had returned home.

After some freshening, he changed into a loose robe and sat down in the room.

Slowly tasting the slightly sour decanting soup, Han Gang suddenly sighed: "Zhang Zihou's wine is not delicious. ”

Yun Niang was beside Han Gang, and after bringing the decanting soup, she helped polish the ink. Hearing him speak, he asked, "What kind of wine did the third brother drink at Zhang's house?" ”

"The wine made from the sugar cane molasses of Jiaozhou." Han Gang said, "The remaining molasses from the family's sugar workshop has also been given to them." Every year, many ships are shipped out of Jiaozhou. ”

"I've never heard of it." Yun Niang said angrily, "Since you took our family's molasses, why don't you send a few jars?" ”

Han Gang couldn't help but smile, "The alcohol medicine is not good, the taste of the soju made is too miscellaneous, and Zhang Zihou doesn't eat it at home." It's all in Jiaozhou. ”

Han Gang is also a pity until now, the raw materials of rum are available, and the brewing skills are not bad, but he can't make good wine. Only once or twice in a while, the next time it is a failure. The only thing to blame for this is the yeast that makes wine. The yeast of winemaking is particular, and if the variety is not right, it will not make good wine. Otherwise, the government would not be able to enforce the ban on alcohol by controlling alcohol and medicine and cellars.

"Isn't there a ban on alcohol?" Yun Niang asked curiously. The burning knife created by Han Gang is famous all over the world, but the Han family's liquor is only enough to send to relatives and friends, and the rest is the raw material of perfume. Boatloads of ships are unthinkable.

"The ban on alcohol is the ban on alcohol, and it is not without workarounds."

The imperial court strictly enforces the prohibition of alcohol, but it will not care about the officials and nobles who make their own wine and eat it at home, and they also turn a blind eye to small batches of gifts and even external sales. However, the scale of the Zhang family's liquor in Jiaozhou was too large, and the last thing was to borrow a land full of gold, brew it in his son's territory, and sell it directly on the local side. Those maritime merchants bought it as ballast goods, transported it to some private ports specializing in retrade, and sold out in a blink of an eye. Fujian, southern Zhejiang, and the taverns over there are all molasses wine from Jiaozhou.

After listening to Han Gang's explanation, Yun Niang nodded, "But the third brother didn't just say this molasses bar?" ”

"Hmm." Han Gang responded.

Yun Niang, who smiled lightly in front of herself, was already the mother of several children, not a little girl who could be fooled with a word back then.

"What molasses?"

Yan Suxin stepped into the door and personally served a bowl of dumplings on a tray. The ajar lid emits heat, and you can ask for the fragrance from afar.

Han Gang laughed and didn't answer.

"It's the wine that the third brother just went to Zhang's house to eat. The official said that the wine of Zhang's privy council was not good. ”

"Bad wine? …… There is no good feast, there will be no good feast, of course it is not delicious. Su Xin wrinkled her nose and pulled Yun Niang out of the door, "Yun Niang, let's go out first, don't disturb the officials." ”

Han Gang picked up the spoon and stared at the steaming heat floating up, but he didn't move.

Cai is really going to do something to Yushitai.

At the time when Sima Guang entered Beijing, in fact, Yushitai had already cleaned it up. But in Cai Cheng's opinion, the cleaning is definitely not clean, and there are still many places that need to be cleaned up again in order to be able to better control the admonition.

It's just that I don't know what Cai will do with Yushi Zhongcheng? Is it to be resolved together, or to invoke Li Qingchen into the Eastern Mansion?

Han Gang thought about it, but most of them were uprooted.

There is still a vacancy in the prime minister's position, but the vacancy for participating in the governor's affairs is gone. Zhang Qi, Zeng Bu, who can he kick down?

Put it in Xifu...... I also want to be willing to agree!

Although Su Song is to replace Han Gang's position, he is old and will not fight for power. Zhang Dian is happy to have this one as a colleague. And let a Li Qingchen, who had just paid fifty years, come in, don't you think Xifu is messy enough? That one is related to the Han family in Anyang.

You can only ask to go out.

Dealing with Yushitai, Cai Qu and Zhang Dian seem to have reached a tacit understanding, Cai Dian wants to be alone, and Zhang Dian has no idea of going to Dongfu for the time being, one east and one west, and join forces to control the court.

The battle between Zaifu and Zaifu depends on who can influence Yushitai more. If Zaisuke wants to control the court, the first thing is to control the Imperial Observatory.

The key to everything is on Wutai, which is a tool used by the emperor to suppress the power of the prime minister, once it falls into the hands of the prime minister, even the emperor has the possibility of being hollowed out.

And no matter which Zaifu controlled Wutai, the others in the two mansions immediately bowed their heads. Even if they themselves are not afraid, if the people below are killed by the imperial history one by one, they will not have any influence in the court.

Zeng Bu and Zhang Qi probably didn't expect Cai Qu to make a move so quickly, and one move away from chess was to tie his hands and feet.

Han Gang was also quite surprised. Now that I think about it, it must be that Cai Cheng has already received the letter from Han Jiang's side, so he will choose to do it now.

Han Jiang is seventy years old. According to the rule, officials are 70 years old and will retire at the latest. Unless there is a need for this old minister to suppress the court, the court will generally not make an exception, and the court's internal affairs will also force him to resign voluntarily, and Yushitai will not let go.

Zeng Gongliang, the father of Zeng Xiaokuan, is the one who edited the "General Essentials of the Martial Arts". Xining was over 70 years old in the early years, and he was still the prime minister in the court, because he supported the new law, so the Son of Heaven wanted him to stay, so Yushitai did not impeach him. But immediately, someone wrote a poem saying, 'Lao Feng Chi can't squat, and he is silent in front of the hungry Wutai', forcing Zeng Gongliang to invite himself.

Looking at Han Jiang's current style of idle clouds and wild cranes, he will not stay for long. And Han Wei and Han Jin are also in their sixties and have not been in the court for a few years. The sons and nephews of the Han family, in the next ten years, may have to rely on Cai Qu and Zhang Dian to take care of them, and there is no need to stay too long, so that people will talk about it.

Eliminating any potential opponent who may be on the top should be what Cai really wants to do. And Zhang Dian, who didn't enter the idea of Dongfu for a short time, is the best ally.

It's just that Cai really trusts Zhang Dian so much? And Zhang Dian really has no interest in the position of prime minister?

It shouldn't be possible. But if Zhang Dian really wants to worship the prime minister, he must use any power he can use, including his own influence. It is precisely because Zhang Dian does not have that idea for the time being that he will put on an attitude of cooperating with Cai Qu. But it is impossible for Zhang Dun to cooperate with Cai Qu in vain, and I don't know what Cai Qu took in exchange for him.

Han Gang guessed for a while, couldn't determine what the conditions were, and planned to ask Zhang Dian another day.

What the hell is going on, Han Gang quickly left it behind, letting them make trouble, he has a lot to do now, and he doesn't have the energy to be distracted. If you have time to compete in the court, you will not resign from the errand of the Privy Councillor.

Li Jie's letter came.

Han Gang looked at the letter while eating a steamed bun similar to a ravioli in later generations.

Li Jie is currently repairing the track in Hedong. From Sanjiaokou to the north to Xinzhou, that section is in the valley between the two mountains, and it has to cross a pass, which is the most difficult section to repair. However, with the existing technology, it is still possible to solve the problem.

It's just that on the matter of whether to pass through Shiling Pass or detour through Chitang Pass, Li Jie and others have disagreements.

From Taiyuan to Daizhou, the road of Chitangguan is far easier than that of Shilingguan. But if you want to say that the road is relatively close, it must be Shiling Pass.

From Taiyuan to Xinzhou in the north, a road to the north through Shiling Pass is. However, the Shiling Pass is steep and dangerous, the entrance and exit pass slopes are steep and the bends are sharp, and the track wants to go to the Shiling Pass, which needs to be chiseled and opened, not that it cannot be done, but at least it takes more time and labor. And to the west bypass Chitang Pass, there are more than seventy or eighty miles to come and go, but other than that, there is not much obstacle. After passing through the valley for more than ten miles, and then turning east, you are behind Shiling Pass.

At the beginning of the founding of the country, the official army invaded the north, and after attacking Jinyang [Taiyuan Mansion] for a long time, they moved troops to Shiling Pass, intending to block the Khitan reinforcements in the north and isolate Jinyang City. However, the Shiling Pass was difficult to overcome, so he divided his troops to attack Chitang Pass first, and after making a detour to Shiling Pass, he attacked before and after, and then conquered it. This time in the Song-Liao War, if it weren't for Xiao Shisan's initiative to withdraw from the two passes, Han Gang's main target would only be Chitang Pass.

There is nothing to detour, and it is convenient to build the road by avoiding difficult terrain. But the detour of 80 miles is the cost of 80 miles more, and the maintenance and operation are much more than passing through the Shiling Pass directly. Li Jie advocated digging a mountain to open a road and take Shiling Pass, while others wanted to make a detour to Chitang Pass according to the plan formulated in advance.

Han Gang psychologically supported Li Jie, but if the parallel railway could not be opened to traffic for a long time, Hedong's economic recovery would be far away.

Moreover, Xue Xiang in Xifu is not young, and he is striving to lay the track from Sizhou to the capital in recent years. The Beijing-Si Railway, he imitated the nomenclature of Hedong, and even predetermined the name of this track. Just waiting for the completion of the railway, it is estimated that he has no patience to wait.

One day late, the imperial court will lose one more income, and Li Jie's plan to chisel through Shiling Pass cannot be supported by Han Gang.

'It would be nice to have a steam engine when there would be. It's not the first time Han Gang has thought like this. Every time I see a mule pulling a carriage on the tracks, the same thought springs up. If there is a steam locomotive, it may not be necessary to dig through the pass to go through the Shiling Pass.

After eating supper in a few bites, Han Gang took down a long wooden box from the Duobaoge next to the desk.

There was a scroll in the wooden box, but when it was opened, it was a very finely drawn icon, which at first glance looked like a promotion chart, but it was very different. The lines on the diagram are tree-like and have many forks, similar to the creature tree that has become very famous now, but there are many places that converge into one.

This is not a promotion map and a creature tree, but a roadmap for the development of science and technology that Han Gang has drawn in private.

The marks Han Gang made on the diagram were intelligible to no one but himself, and the symbols on them made the whole diagram look like a diagram related to arithmetic. It's like the Jia Xian Triangle drawn in the new issue of Nature.

In this issue of Nature, there will be an introduction to Jia Xian. At the same time, Jia Xian's method of multiplication and multiplication and the method of seeking incorruptibility by multiplication are re-interpreted and elaborated in mathematical symbols and mathematical language that are now gradually standardized.

Si Tianjian is not without talents, and in arithmetic, there are many capable trick officers. Jia Xian is one of them. His "Yellow Emperor's Nine Chapters of the Calculation of the Scriptures and Fine Grass" has been widely circulated in the world, and the programmed high-power method has benefited many mathematicians, but he has long been gone, which makes Han Gang feel very regretful. If Jia Xian were still alive, there would be many more vacancies on his technological development roadmap.

The steam engine was very far behind on the road map, and before that there were boilers, pumps, pistons, gears, bearings, as well as pressure gauges and valves. Han Gang had a superficial understanding of the development of the steam engine, and could only list these inventions, and was not sure which ones could be omitted and which were absolutely necessary. Compared with many pre-technologies, the theory of the steam engine is easy to elucidate.

He is already writing an article about motivation. Human, animal, wind, and water power were all taken out and analyzed one by one, and then steam power was elaborated and advocated. Among them, the power generated by the transformation of water into steam also has something in common with the principle of firearms, and Han Gang took it out in the article to explain and clarify the difference.

It seems that this is only a theoretical analysis, but in fact, it is to explain the direction in which firearms and steam engines should be improved and invented. Anyone with a discerning eye can see it.

This pile and piece by piece must lay a good foundation in advance. If there is no foundation, it is a tree without soil and a fish out of water, and only when a trend is formed among the people and there are enough beneficiaries, so that when they return to the two provinces, they will have enough confidence to promote real development.

Han Gang rolled up the chart again, put it away, and set it aside.

With a long sigh, patience and time are still needed!
