Piao Tianwen    Zhao Zhen's face turned cloudy, but he didn't say anything.

His personality is softer than Zheng Lang. If we talk about his belly, he may be even bigger than Zheng Lang. For example, he mentioned Guo again to Erxiao, Wang Anshi and Sima Guang more than two months ago, which made him very angry. Now he looked at them, but now he had a smile on his face. In fact, in the past few days, his anger had already reached the sky.

But it doesn't mean he is not smart.

If he was not smart, with his personality, something would happen to the Song Dynasty.

Needless to say, it is possible that the cousin of Uncle Bawang’s family was involved. It is not easy to say it, and said, “Zheng Qing, I know it in my heart. You guys go.”

No consent nor disagreement.

But after returning to the palace, he immediately sent someone to Shangcai County to check it out. Can it still be found?

So an order was issued to force all the five princes to return to the capital!

The sky outside was very gloomy, and Sima Guang asked in confusion: "Zhuangsheng, why did you say it directly?"

"Why can't you just say it?"

Sima Guang meditated carefully and said after a while: "I understand, it's right to do this."

Gao Yanei is not worth cherishing, but the princes are troublesome. They have no real power, but their identities are very noble. As ministers, they should show polite respect. It is just that a few people are wrapped together, which is not good for Zheng Lang. How can Zheng Lang do them? Telling it out makes people seem open-minded. No matter whether these princes have planned anything with Gao Yanei, it is wrong to live in the home of a minister as a prince. No matter who is worried, what else does Zheng Lang have to do with his reputation now?

After saying it, it is like a child being beaten by his brother. Can you ask a few people from outside to beat his brother back, or use a knife to stab him in the back? The most rational way is to tell your parents to ask your parents to make decisions.

"So I said, we are still young, and we learn to observe is the training stage and the growth stage. At this stage, we take the initiative to avoid trouble..." Some Zheng Lang did not say that, to be honest, he didn't want to provoke Zhao Yunrang. Why bother? Zhao Shu can't be considered a real bad emperor in the future, but his mind is very abnormal...

"yes."

I started to ask the second primary school to buy books. Taipingzhou is not a big state, there are not many products, and there are also few books. If you want to compile a book, you must bring enough books to search. There are still a few more students to study, and you need books even more. There is no need to hurry to write a pen, ink, paper and inkstone, you can just put it in a few words.

Then he said to Mr. Lu: "Your Majesty, you have summoned me. It is very likely that the letter will be issued in the next two days. Say to your father, I will give him two gifts, but I will also bring a word for me. He is the prime minister, and he must have the prestige of the prime minister. He must not be too utilitarian, and cannot fight for power and open a river of struggle for the sake of the party."

Mr. Lu blushed.

Things are divided into two parts. There must be a struggle between the kingdom, and it was impossible to avoid that era, but there was no serious party struggle. For example, the dispute between Lu and Li is a struggle between the kingdom. Everyone is competing for some reason, so they will not delay national affairs.

The result of the party struggle is what you agree with. I will inevitably oppose it. I will inevitably agree with what you oppose. How much harm will it be?

Later, we couldn't blame Fan Zhongyan all. Lu Yijian first used the Seven Injury Fist and then the Magical Art of Wedding Dress, so he got himself in charge. Fan Zhongyan forced him again. The more he forced him, the more he forced him, the more he forced him, and Fan Zhongyan forced him. The party struggle began. Fan Zhongyan definitely didn't want this result.

No one dares to doubt his heart! No one dares to doubt his character!

Lu Yijian also didn't want it either. He was greedy for power and was still a prime minister who did practical things and would not want to bring the Song Dynasty to a bad road. But it was the Fan and Lu dispute that the civil officials of the Song Dynasty gradually became divided.

Zheng Lang could only say this and then took out two pieces of paper from his luggage.

One is a black gunpowder formula. The black gunpowder formula in the Song Dynasty was slightly better than that in the Tang Dynasty, but that formula is still messy and not very powerful. The black gunpowder formula is accurate, with pure ingredients, and not very powerful. But at least it can be used for quarry, logging and blasting of mines.

This is the most correct recipe.

It is possible that the impure of raw materials is reduced in power, and even impure raw materials will affect the proportion of ingredients. But it is definitely several times more powerful than today's black gunpowder.

I don’t know what impact it will bring, but it seems that the formula gradually became more accurate in the Ming and Qing dynasties, which is not very good to compare, because the Qing Dynasty also used weapons made of black gunpowder to fight the Ming army, but cold weapons still dominated the mainstream. It will probably work, but it will not play an absolute role.

This is what Zheng Lang gave it.

After the recipe, he deliberately wrote this matter and then said, don't leak it.

It was deliberately reminded that the Song Dynasty actually had strict supervision of some secret weapons, such as the Divine Arm Crossbow. Even if all of them were killed in battle, they would have to destroy the crossbow before they died, so that the enemy could not know how it was made. However, it was still spread to Yuan Jin's hands.

It is also noted again that its explosive characteristics are the air pressure generated during violent explosions, which is its power. Therefore, when blasting, it must be sealed and ignited the sealed gunpowder with leads to exert its power.

The second picture is the divine arm crossbow. Zheng Lang clearly marked some of its key characteristics, with a bow body three feet three and a string two feet five. He used mountain mulberry as the body, sandalwood as the trunk, iron as the barrel, steel as the machine, mastarch as the thread, silk as the string, shooting three hundred steps, and penetrating the heavy thread. He also drew an imaginary picture.

Lu Gongzhu didn't understand this very well, and the bed crossbow also reached this range, even further.

But if you give Lu Yijian, you will know its power. The bed crossbow is operated by multiple people and is bulky, but this crossbow is operated by a single person. As long as you have strong strength, you can open it.

However, Zheng Lang deliberately noted that to reach this range, a specific mechanism was needed, and he did not expect it.

This was confirmed by later generations repeatedly proof.

According to the style of the imaginary picture, it will definitely not reach this range. If it is well made, it will at most be a slightly powerful tread. In addition, it should have a part composed of gears so that its range reaches 450 meters and can also penetrate heavy armor.

I don’t know what this part will look like, but if the black gunpowder is successful, the court will definitely send more craftsmen to research and develop.

He couldn't imagine it, but there would be craftsmen who could imagine it. Moreover, the history of its original appearance was in the era of the Emperor Shenzong decades later.

Zheng Lang also talked about its original shortcomings. Although the range is long, it requires those with high arm strength to pull it away, and the accuracy is not very high. When facing the enemy, it is not as fast as that of ordinary powerful crossbows in the Song Dynasty.

But it is still very powerful. At one time, it once caused the Jin people to feel serious fear.

Lu Yijian got these two pieces of paper, but he didn't know the importance of it.

This was not what the prime minister did, but Zheng Lang spoke very seriously, so he handed it over to Wang Deyong. Wang Deyong gave it to the relevant officials to test it.

There is a workshop in Tokyo that studies gunpowder, which is one of the eleventh orders of military weapons. The sulfur used in gunpowder is imported from Japan, and each of them has a systemic method for manual production, so that each can recite its own method and prohibit its transmission.

However, it was still circulated. The Khitans used some methods to obtain gunpowder formula and related weapons, and read artillery in Yanjing Daily and showed their power to the Song people. The Song Dynasty had no choice but to make an attacked ostrich again, passively banning the field to buy sulfur and flame salt.

But something happened.

I don’t know the severity of gunpowder, so I still produce it according to the original gunpowder production process. However, the proportion has changed, and it is sealed with layers of thick oil and sesame paper on the outside.

The three ingredients are ready-made, and the oleifer paper is also ready-made. The recipe is obtained and it is ready in less than half an hour.

Zheng Lang is also considered his own relative. Wang Deyeng pulled two other bigwigs from the Privy Council, Cai Qi and Li Zi came to gunpowder together. Although this thing is "safety gunpowder", it is only relatively safe, so it is located outside the city and not far from where the Yan Family Inn is.

When the three big bosses arrived, the officials inside became even more nervous. They didn’t know where the recipe came from Wang De’s hand, so they naturally had to express it well.

So I added another portion, which was more than 200 kilograms, wrapped in layer by layer of lump paper.

To test the power, I dug a shallow pit on the ground, covered with some floating mud, leaving behind the leads.

Several big bosses were talking, the military weapon supervisor, the chief supervisor, and the gunpowder supervisor to accompany him.

Cai Qi asked in confusion: "Grandpa Wang, why did you bring us to watch?"

"It's the recipe given by Lu Yijian."

"Grandpa Lu, where did he have the graceful pleasure?"

"It's not that he has a good mood. It's the recipe written by the top scholar. He asked his son to bring it to him. He said it carefully. So I'll take you over and see how powerful it is."

"Zheng family."

"Um."

The big guys didn't take it seriously. This is called professionalism, it's gunpowder, not Confucianism. You can do whatever you want. But you have to look at the recipe for the top scholar. Don't be able to make a sound for a while.

With gunpowder weapons, their power is very small and they are not used much on the battlefield, which has also caused several big shots to be despised.

The little official asked, "Can you cast it?"

"Let's go."

"Several husbands, please stand a little further."

In order to show, the amount is a bit large, and the place where I am buried is only a hundred steps away, otherwise I will not be able to see clearly. "It should" be fine, but it is better to be careful.

The minor official urged the officials, and the big boss walked out again, about 150 steps, and all stopped. Then, as the minor official directed the craftsmen to evacuate, they stood a little further. The minor official took out a tongue of flame and pointed it on the lead. He didn't know that he wanted to point the lead and observe it. The big boss left after taking a look. But he had to continue researching and developing in the future and had to obtain first-hand information. So he stood seventy or eighty meters away, staring foolishly.

When Wang Deyong saw him concentrate, he praised him: "This person is good."

Have a professional spirit.

This is OK, but don’t put so many portions on the battlefield, and if you go to the battlefield, you will use more than 200 kilograms, what should you throw them out? Or if you buried it on the ground like this, the enemy will be foolish, stand there and stay motionless, and watch you send someone to ignite the blast?

If you want to experiment, it is enough to use a small bag of more than ten pounds.

The sad beginning.

...

In the inn, the two little ones were talking to Zheng Lang.

Sima Guang asked: "Zhuangzong, why did Prince Lu look so serious when he mentioned Wanchunwei?"

"There is a reason in the middle. This embankment is also called Qinjia embankment. Since the Taiping Xingguo period, the imperial court has repeatedly wanted to build it, but it has not been built. It is because there is a lot of controversy. At this time, Taipingzhou is mostly lakes, and the water surface is discharged into a dike, which makes the flood water of the water surface have no home. When the summer and autumn flood season comes, the upper flow water rises. The flood peaks are flooded, which will cause floods. The southwest of this embankment is close to Jingshan Mountain. Along the foot of the mountain, the water of the Yangtze River can only flow through the mountain gorges. When blockage occurs, it will cause disasters in Jingshan. Some people believe that the place where the embankment passes, the dragon lurks at the bottom. In the past, this embankment was destroyed because of this. After this embankment was destroyed, it has the benefits of picking water and can feed more than a hundred families. Once it becomes a dike, it will inevitably cause them to resist and dissatisfaction. There is a large lake in the southeast of this embankment, and the embankment has been hit by wind and waves for a long time. It is difficult to be strong for a long time."

"What about the top scholar?" Wang Anshi asked with interest. He didn't believe that the teacher was a person who followed the crowd.

"From the perspective of this dike, there are two lakes in Danyang Shijiu, which stretches three to four hundred miles away, which is enough to accommodate floods. Moreover, there are swamps and tidal flats around this dike. Usually, it is a beach, a slum or a siege. When it is flooded, it can spread into a lake, and the area is four or five times the size of Danyang Lake. It is enough to store water. The west side of this dike is connected to the Yangtze River. The flood flows very quickly. Do you believe the matter of dragons? Master said, "It is strange that the dike is not messy!" But it may be that the dike will spread through the dike. The water will form a pool for a long time. The deeper the pool will cause the embankment to collapse. People are puzzled, so they think that the dragon is a trait. As for the people of the dike, they can have tens of thousands of mu of arable land and hundreds of thousands of mu of arable land. They can share some arable land for them to live and work in peace. Why do they object? Therefore, it is not a big problem to build this dike. But the problem is not here."

"Where is it?" Wang Anshi said. It can also be seen that his personality differences with Sima Guang and Lu Gongzhu. Lu Gongzhu listened quietly. Sima Guang was not very interested. He only cared about whether this matter could bring benefits to the country and Zheng Lang.

But when Wang Anshi heard about the water, he felt energetic.

It is possible that he grew up in Jiangnan for a long time when he was a child, so he is more familiar with this.

"The main reason is that there are many people. If we spend two or three hundred years safely, we don't have to expand our territory. As long as we keep the territory unrealized, the population exceeds 200 million. There are so many people who have to open their mouths to eat. The more people there are, the more they need sufficient arable land and will rush for land and fields everywhere. In the future, it is not just this dike. It is possible that all the swamps and tidal flats in Taipingzhou will be turned into tillage and tidal land, and even the Danyang Lake can be turned into tidal land. Then, when the flood water comes, the breaking of the dike will happen from time to time. If the water storage function is lost, even in the south of the Yangtze River, drought may occur."

"This is not very good," Sima Guang said.

"It's not very good, but you can see that the country's grain is tight. Is it good to develop in Hebei, Henan and Shandong? Why did the Yellow River and Bian River happen again and again? The land yield per mu is only more than two stones, but the polder fields can reach a huge amount of five stones."

"That's true for the top scholar. But whoever sets the precedent will cause trouble for the censors at that time."

This is what Zheng Lang is most unhappy about.

I worked hard, if I opened several large dikes in Taipingzhou and converted them into three to four thousand hectares of farmland, I could support tens of thousands or hundreds of thousands of people, and I would pay 100,000 stones of grain and countless taxes for the court a year, but as long as a little bit of trouble, the ministers would cause trouble for you.

Once the dike breaks, people will definitely die. Even if no one dies, the losses will be huge. The impeachment begins!
