Song Jiu saw Pan Li'er, he felt still amazing, but it was not like the beginning, after all, he was not Duan Yu, and Yuping's finger wrapping softness also played a part, and he could speak calmly, and said: "Little lady Pan, I didn't pour your father any sweet words, on the contrary, I was very bitter when I went south, and I went out for a few months before I came back, and I gave your father and they kept asking, and my head was too big, forcing me to go back to Beijing all the way in order to grab time." ”

"Daddy he'......"

"What's wrong with him?"

"I'm going to tell you something."

"Little lady Pan, how old are you this year?"

"I ...... You don't want to know the way. ”

"Let me guess, guess right, and I'll tell you the story of the monkey." Song Jiu can calm down in the face of Pan Li'er, and he will be able to use some small means.

"Good...... No, why did you guess right and tell me a story? If you guess wrong, you can only tell. ”

But no matter how quickly Pan Li'er reacted, she still entered the court, Song Jiu said: "Okay, seventeen." ”

"A story."

"Eighteen."

"Two stories."

"Sixteen."

Pan Li'er didn't have to say anything, Song Jiu asked several times at this age, but the Pan family didn't answer one by one, and finally came out today. Song Jiu was dizzy, he was so young, he almost became an animal, and there were many married people at this age, but he could afford to wait. At the same time, it proves that Pan Li'er developed early, and last year Song Jiu thought that Pan Li'er was sixteen or seventeen years old.

"Tell a story." Pan Li'er said that Sun Wukong's fate made her miss it.

"Your father, him."

"You don't want to know the way, you still talk about the monkey." Pan Li'er looked around carefully, and the people gathered around to watch Zhao Kuangyi cut the ribbon in the distance, no one paid attention to them, and said: "What you just said, you can't go back." ”

"I'm not going to tell you a monkey, I'm going to tell you the story of a princess. Better than a monkey story. ”

"I don't want to hear that princess."

"It's not that princess, it's a princess from a Western country, you listen to me," Song Jiukai told the story of Snow White. Pan Li'er cupped her cheeks and asked, "Bad guy, how did you come up with so many stories?" ”

"This ......" Song Jiuzhen couldn't answer, he pointed to the other side of the river and said, "If I arrange it according to this story scene and invite some people to perform, wouldn't it be better?" ”

"Playground?"

"There's going to be a lot of fun stuff in there."

"What kind of ability is that, it's just a Yu Wenkai."

"Yu Wenkai, I don't care to do it, and it is impossible for His Majesty to let a Yu Wenkai appear in the court. These ingenious ways are used correctly, such as Li Bing and Zheng Guoguo, do they have any credit? The monkey story I said, the golden hoop stick in his hand is 108,000 catties, isn't it very heavy? ”

Pan Li'er nodded, Pan Mei also went into battle to kill the enemy, but he still couldn't do it if he lifted a hundred catties of weapons, how many times is one hundred catties of one hundred catties?

"Look at the mound across there."

Song Jiu refers to the playground of the future, you can't get a high mountain, but that's a place to play, just on the terrain, build some high hills and a small artificial lake, as a landscape, this year is too late, next year will start greening, for the time being, it is still bare, Song Jiu said: "It's not high." ”

It can't even be counted as a mound, so it's not tall.

"Its real height is only a little more than seven zhang, and the radius is less than eighty zhang, but it has about four thousand square meters of soil, one side of the soil is five thousand catties, and such an inconspicuous hillock weighs tens of millions of catties.

"Then you."

"That's a story, but if it's a well-developed physicistic, you can make such a heavy thing fly in the sky, can you still use Yu Wenkai to describe it."

Pan Li'er was a little frustrated, Song Jiu was a man who went to heaven, and he couldn't refute it, and suddenly laughed: "You are in big trouble, there is a rebellion in Bashu, and the court has made a few balloons, ready to send them to Bashu, to reconnoiter the military situation for the soldiers, who knows that the emperor of the Dao Dao is curious, and a few days ago he sent someone to pull this balloon to the palace, and secretly put it up at night, and then he sat on the balloon for a long time and was reluctant to come down, and the next day the ministers impeached one after another, and also talked about you." ”

"Ah, there's something."

"I don't believe you asked the second king to go." Pan Li'er gloated and said, the capital went up that day, but she didn't go up, so she could hear the second brother who had been there.

Song Jiu scratched his head, and then laughed dumbly. This question doesn't matter, if it weren't for a few decades later, then Song Jiu would become a real disaster for the pond fish, letting Bao Zheng, Ouyang Xiu and others spray to death. This is what Zhao Da wants to go up, what does it have to do with himself. On the contrary, it can make Zhao Kuangyin curious, which is a good thing and not a bad thing.

"How heavy is that little mound?"

"To use an analogy, if you move it a hundred steps away, a hundred big men, will it take twenty days?"

"Probably."

"In fact, it is easy to calculate, a hundred steps, a tortuous distance, plus the manpower of digging, the actual round trip is 300 steps, a person's walking time is 7,000 steps per hour, that is, an hour only bears 12 loads, five hours a day, and then deducts the wind and rain, and the waste of time, a day can only bear 80 loads, a hundred people are 8,000 loads, a load is less than 150 pounds. So it takes about 20 days to move a home a hundred paces away. How much you say it will weigh? ”

"You are really Yu Wenkai!"

"What Yu Wenkai, this is just a simple earthwork calculation, there is still a month, as long as the students in my school can graduate, they will all count, are they all Yu Wenkai? The bridge is the real complex science. ”

But Pan Li'er didn't dare to pull down with Song Jiuxian anymore, and about Zhao Kuangyi also finished cutting the ribbon, and the people were still watching the construction, but the people began to disperse gradually. It's not a hug and a hug, and it doesn't matter much in the early Song Dynasty, but the Pan family is everyone, Pan Li'er saw that the crowd began to disperse, and hurriedly got up to leave.

Song Jiu asked again, "What's wrong with your father?" ”

"Because you went south, my father and Wang Zhizhou were tired to death." Pan Li'er turned her head and raised her fist, the actual truth is that Pan Mei wrote a letter to her family, and asked Mrs. Tian to see how Song Jiu was doing, not saying that Song Jiu was a quasi-son-in-law, but with that fancy meaning. Later, Mrs. Tian secretly inquired, including the good and bad prices of the Zhao brothers, and the good side outweighed the bad side, and Mrs. Tian also had some agreement. The problem is that Song Jiu never sent someone to the door to propose marriage, and included Yuping in the room. This is really wronged, nothing happened to Song Jiu and Yuping, the outside doesn't see it that way, and when they entered the door of the Song family, God knows if anything happened to you. The Pan family is even more difficult to say.

It's weird......

Song Jiu also set off, the two projects are not less money, the state finance is recovering, but it can not be said that it is too good, the Yellow River in the Zhou Dynasty decided in Dongping County Yang Liu Si, the prime minister Li Gu sent people to plug the embankment, but there are many hidden dangers, the Song Dynasty also has many experts, some people proposed, Zhao Kuangyin sent people to inspect, proposed to govern the ancient embankment, because of the use of a lot of money, the force is large, the speaker thinks that it is not feasible to stop, and then take the middle strategy, build a remote embankment outside the embankment to block the flood waves, as a result of last year, the river decided in Dongping Zhu Village, so that the land of the seven states suffered from floods. If it weren't for the fact that the imperial court got a lot of money from Bashu, maybe this time the construction of the two projects would attract the impeachment of the minister. Therefore, the official who led the lead was not Song Jiu, but Han Chongyun, the commander of the palace in front of the palace.

General Han, who used to crisscross the battlefield, became the head of the construction, I don't know what he thought in his heart, Song Jiu dealt with him a few times, and he was not very happy to see it. But Song Jiu was not afraid, his two sons Han Chongxun and Han Chongye had a good relationship with Song Jiu, and they also took 900 yuan to invest. No matter how unhappy General Han is, he will not vent his anger on himself.

Song Jiu only played the role of a technical official in the middle.

But Song Jiu didn't dare to be careless, the responsibility for the accident would be all his.

Begin to dig the foundation, the so-called Hongqiao and the principle of the brushed bridge are very simple, Hongqiao is also called the flying bridge, its principle is to make the whole bridge into a whole, the overall force, the pressure is transmitted to the pier below.

If the bridge can't be turned into a whole to bear the weight, the consequence is that once the load is too much, the waist will break!

The nature of the brushed bridge is similar, but its force is to the sting, and the pressure is lifted to the slang through the drawing, and then it is borne by the foundation of the bridge pier and the shore, and it is also a whole. So it has to be reinforced concrete. In the history of the Song Dynasty, only the wooden wedge and wood caused a rainbow bridge with a span of more than 30 meters, which was the crystallization of wisdom, and Song Jiu could not do it.

The main part of the bridge is not the deck, but the four piers. In fact, in ancient times, there were also welding techniques, and the Song Dynasty also had the segmented casting and welding method, in which the device was made, the bronze melt was cast, or the tin melt with a lower melting point was cast for welding. It is not electric welding, but these metals can be forcibly burned into a liquid first. It is very expensive and the welding is not very strong. Therefore, like this kind of large-scale reinforced concrete, Song Jiu not only adopted a part of welding, but also made many large screws, which were screwed on the holes that had been burned in advance, and gathered various steel bars and steel bars into a whole. Including the blast furnace has also adopted this technique.

If you don't take into account cost and waste, at least for now, it's still working well.

Zhao Kuangyi finally saw Song Jiu, called him over, and said in a low voice: "Don't be afraid of spending money, don't have an accident." ”

Song Jiu nodded, Zhao Kuangyin ran to the sky in the middle of the night, and the minister would definitely be anxious if he knew it, and if he said himself, he would definitely say Hezhou. Once something happens, he will not have a good life, and even Zhao Kuangyi, who advocates support, may be impeached.

But now the problem is that iron is too expensive.

A pound of iron is 30 yuan, and a ton is more than 50 yuan, which is turned into steel, and the loss of labor is at least 100 yuan. Like themselves, these steels have been further forged several times, and some have to become drawn, steel cables, screws, and components, not counting the labor cost, will reach 150 times! 100,000 RMB!

I can only compromise between saving steel and quality.

After thinking for a while, he said: "Second king, I also know that there are ministers in Lu Dao who say me, but the two kings can rest assured, they will see that Wei Chen will bring more returns to the imperial court, and even in the future, if Wei Chen has time, he can improve the copper smelting technique." ”

"Don't worry, you should focus on the bridge first, you can take your time," Zhao Kuangyi said eagerly, this is better, it is terrible that Song Jiufen has too many hearts, and when the time comes, nothing will be accomplished, and he said: "You work with General Han, he is the founder of the country, you have to let more concessions." ”

Weichen knows that he is one of the top ten meritorious generals of the founding of the country (after the founding of the Northern Song Dynasty, the military generals are ranked as Shi Shouxin, Gao Huaide, Zhang Lingduo, Wang Xianqi, Zhang Guanghan, Zhao Yanhui, Han Chongyun, Li Jixun, Luo Yanhuan, Wang Yansheng. The ranking of the staff of the overlord is Liu Xigu, Zhao Pu, Lu Yuqing, Shen Yilun, Chu Zhaofu, Li Chuyun, and Wang Renzhen. And General Han is not bad for me. Song Jiu suddenly said, "Second king, you come with me." ”

After all, the money is used too much, so I simply let the court look at something good and block some people's mouths.
