Due to the times, the pace of life in the Song Dynasty was relatively slow, at least slower than the later generations of Song Jiu. There were many places to enjoy when I was free. The first was shopping. The east and west cities of the Song Dynasty gradually disappeared, and more than 20 commercial centers of all sizes were shopping.

The second is an entertainment venue. Go to the tile tram and watch artists perform various performances. If you are lustful, go to the brothel. Third, visit the garden. There are countless public and private gardens in the capital. Some are open, some are not open. No matter how much money the non-open flowers are, they cannot enter. If you open, there will be no charge. Yujie is undoubtedly one of the preferred areas. In mid-May, the peach and plum blossoms have faded and the lotus tea has not yet bloomed. However, the scenery is also charming. These trees were planted when the firewood rose. Now the branches are lush. When the summer wind blows, the green shadows sway. In the fragrance of the lotus leaves, countless green pears, peaches, apricots, and half-even yellow and red plums are shaking among the leaves. If the branches are close, the greedy child will pick the half-ripe plums and put them on his mouth and grin sourly.

The weather is hot in May, and there is another leap month this year, which is even hotter.

But it wasn't the hottest time.

There are many people shopping. When you walk to the end of the Imperial Street, there is the tall Xuande Gate. Behind is the imperial city, which is free from entry for idle people. Someone saw a painting on the wall of a house on the Imperial Street.

The painting is a bridge that has never been seen before, with curved above and curved below.

This is the first advertising painting launched by Song Jiu. Four painters are invited to go home. You don’t want any aesthetics or artistic conception, but only seek realistic and three-dimensional to paint this bridge, which is different from the location of the Hongqiao Bridge in later generations.

The Hongqiao in the Qingming River During the Qingming Festival is a little further down at the intersection of the two Bian Rivers. Song Jiu has also verified the location, which is about ten meters away from this intersection. Because there is a pointed mouth here, the bridge building distance is shortened and the difficulty is reduced.

But a new problem comes out after the bridge, water!

The length of the Hongqiao Bridge was about 30 meters, and it was sufficient. Later, the ship industry developed in the Song Dynasty, but the largest river boat was only 20,000 stones, less than 1,000 tons, and the width of the boat would not exceed 13 meters. Moreover, there were few such large ships sailing into the Grand Canal Bian River, and most of them were active on the Yangtze River. The Bian River was still a ship with a capacity of less than 500 tons.

However, this length is a problem. The Bian River must be more than 30 meters wide, and the widest place can reach 300 meters. Because the city site is compressed, the narrower the city goes to, and the length of the bridge is less than 20 meters. In history, choosing the location to build a bridge is saved. The length is saved. If the two waters meet, the water flow will rove, causing the water flow to change impermanently, rather than going down smoothly. In addition, the river bundle is narrow, and then there is a scene in the Qingming River Over the River Map. It is fine to face the middle of the Hongqiao, but this water is disobedient and it makes the ship difficult to control. Therefore, the people on the boat are nervously steering the boat, and the pedestrians on the bridge shout in a hurry. Advantages, the difficulty of building a bridge is reduced, the cost savings, the disadvantages are not conducive to navigation, and the part of the river in the river is thrown out.

So Song Jiu inspected several times, moved westward for about 400 meters, and the span of the bridge increased by at least six or seven meters, and had to build a rainbow bridge in the South Bian River. The South Bian River gradually disappeared, and the Northern Song Dynasty might not perish. In two hundred years, all the South Bian Rivers were moved to flat ground, but the bridge would cost money and the cost would double! But there were more advantages, the Hezhou circled in, and two rainbow bridges, one large and one small, stood on the river surface. How beautiful would the picture be? At that time, just tourists who came to watch could make money for the Hezhou.

Others are not painted, only two imagined bridges, as well as sailboats, a bright moon in the sky, reflected in the water, two bright moons, an extremely beautiful double bridge picture.

There was only one painting and no text description. The people did not even think of the desolate river island outside Dongshuimen, and asked curiously: "Where is this bridge?"

Where is it in Song Jiu’s mind!

However, dozens of particularly smart people saw the significance, including the Zhao brothers. They heard that the painters sent by the Later Zhao Kuangyin to copy them and took them to the palace for circulating.

That day, Song Jiu painted it with his fingers dipped in tea, and it was not real. Now it became a real picture. All the ministers immediately thought of its significance. In the past, they were all plan bridges, and the height of the bridge hole was insufficient. There were large ships in the Yangtze River, but they could not enter the Grand Canal. But the larger the ship, the more the freight cost, the lower the cost. The lower the cost can enrich the national treasury, or reduce the taxes of the people, and also reduce labor. This is a very important meaning. It is a path, including a crane, but even Zhao Pu had to admit that although it is a path, it is used correctly. If a crane is used on a large scale, it can save more than 20,000 labor in a year, and it will not be amplified to save 240,000 labor in the country. The capital is the starting point and the end point, accounting for at least 20,000 of the country's transportation. That is also considerable. After saving 10,000 labor, it can be put into production, which not only reduces the burden on the people, but also creates more wealth for the country.

The meaning is extraordinary, can it be made?

There are single-hole bridges and Zhaozhou Bridge. Many bridges in the Song Dynasty were imitated by the technology of Zhaozhou Bridge. Not to mention the small holes to release floods, but only the bridge deck. It is the same as Zhou Bridge. The Song army trained the navy in Jinmingchi. However, how did those warships go out? Drop all masts and ships, and then press them down. Only then can they leave the Zhou Bridge and other bridges in the city, and reassemble them outside the city. It is very troublesome.

But no matter how troubles it is, it can be built. Nowadays, such a rainbow bridge, or flying bridge, is a bridge under the bridge, which is like a bright moon, and the technical difficulty will be increased ten times. Therefore, the king and his ministers are a little bit convinced and suspicious.

Not many people know the truth.

The common people cannot find this double bridge and think it is just a painting. They can draw whatever they like, and can also draw gods and ghosts. How many ordinary people have seen real gods and ghosts?

Some people think that if it really appears, they must go and take a look, and someone will just take a look.

In addition to these big names, there was also a group of people who knew that Fu Zhaoshou and Luo Yanhuan's son Luo Gui, and Han Chongyun's son Han Chongye ran to the Song family. Song Jiu was not there, and he took the craftsmen and students to build a house on Hezhou.

This will be the core technology of Song Jiu in the future, so the house will be very strange. At this time, the Song Dynasty had immature glass techniques, which were burned to the eye, so they changed to burn glass together. The glass sheets were no longer expected, and there was no cement, but other things could be replaced. The courtyard wall was very tall, and the roof was built with glutinous rice flour lime, and there was a lot of pointed iron inserted. The iron nails and caltrops were also very expensive. Don't ask for them, let Li Blacksmith beat them at will, just want the top to be pointed, the sharper the better. Prevent people from climbing.

At the same time, there is a second defense on the roof. A layer of iron net is spread, and many animal traps, mouse traps and caltrops are arranged on it. Don’t expect to pry tiles into the house. There is a third defense under the eaves, with a large iron lock and an iron fence on the windows. Song Jiu even plans to arrange some mechanisms in the house in the future.

The three of them were stunned and asked, "Jiulang, what are you doing?"

I was ashamed, the palace was not that nervous.

"Luo Dalang, Han Erlang, Fu Sanlang, didn't I say that I would turn this river continent into the most beautiful and fun place in the entire Song Dynasty."

"What does it have to do with this room?" Fu Zhaoshou looked at the various "hidden weapons" on the roof and asked cumbersomely.

"If you want to change it, you need some technology. This technology will be developed here. How can I not pay attention to it?"

What technique is worthy of your mobilization? The three of them couldn't help but look at the strange wall again. Fu Zhaoshou's forehead was sweating. He asked the main thing first: "Jiulang, did you ask someone to paint the painting on the Yu Street?"

"I rented all the walls of that house. Whose painting is not my painting?"

"Can the bridge really make it?"

Fu Zhaoshou's father Fu Yanqing was at home to support his old age, but no one could underestimate the Fu family. The nine Fu brothers were all important generals who led the army and had a relationship with Zhao Kuangyi. There were often some distinguished guests at home, including his son-in-law Zhao Kuangyi, but it was hard to say that these people like to play with each other. For example, Zhao Kuangyin married his daughter to Wang Shenqi's son, and Luo Gui signed up for a child marriage, which was Wang Shenqi's youngest daughter. He was a relative. He was not given military power, and he had to give wealth and honor. Rich means money, and honor is another status, high-ranking officials and joint marriages.

So Fu Zhaoshou has often heard these big names discussing this bridge these days, otherwise he would not have thought of how important this bridge was.

He came to Hezhou and his paintings were from Song Jiu's hands. He immediately thought that Song Jiu would build this Shuanghong Bridge on Hezhou.

Song Jiu nodded.

Someone imitated this rainbow bridge in his previous life. He went to see it and saw the diagrams of its various parts, and understood the principle a little bit. The difficulty lies in the fact that the bridge used cement reinforced concrete, which was not available in this era. How to implement the principle into reality and become reality requires the assistance of some craftsmen who are proficient in bridges. But there is no big problem.

Why is the first painting Shuanghong Bridge? Song Jiu also thought of its benefits. No matter how much money is paid to the court in the future, the court will support it based on this bridge alone.

"Can it really be made?"

"If this bridge cannot be built, it will be even more difficult to deal with next. Fu Sanlang, it is just the first painting, and there are nineteen giant paintings behind it!"

"What are those nineteen pictures?"

"I said that day, you will know when you come out."

"No, I have to say it."

"I won't even say it if I beat you to death."

"Eat wine, go eat wine," Han Chongxun said.

"I can't eat wine today, so I have to go back and write those three formulas."

The answer was announced by Dr. Zhang, but Dr. Zhang was very unhappy. However, after such a fuss, Dr. Zhang and Song Jiu no longer spoke as arrogant as before. Song Jiu wondered if Zhao Kuangyin would have guessed this result. It was not that Song Jiu did not respect them, but that they took themselves too seriously. Song Jiu had "education" not as high as theirs, his official position was not as high as theirs, and his reputation was not as good as theirs, let alone their age. But now Dr. Zhang felt guilty. As long as Song Jiu was not too much, there would be no serious conflicts in the academy.

"Where are some Pan family's sons?"

"Are you still thinking about Pan Lian'er? But there is something bad about it."

"What news?"

"I heard that General Pan's former favorite general Zhang Bing sent someone to propose to the Pan family for his son Zhang Zhaoyun, and Aunt Tian agreed with him (note).

Song Jiu was stunned when he heard this. It would be very difficult for him to marry Pan Lian'er. If the Zhang and Pan families were engaged, they would have no hope at all. They couldn't help but ask nervously: "Have you agreed on the two parents?"
