The Jin army besieged the city, and the Song emperor’s daughter died

Chapter 59 Enjoy Yu University
The discussion lasted a whole day, some nonsense, some well-founded.

Back in the imperial study, Zhao Fujin read through these meeting minutes several times. The more he read, the more he felt that the Song Dynasty had too many shortcomings to make up for in the military.

Let’s not talk about things like military horses and armor that can’t be dealt with for a while. After all, Zhao Fujin is not confident enough to start a field battle with Jin Guo now.But in order to deal with the Jin army's attack on the city in half a year, there are several things that need to be resolved as soon as possible.

The first is the issue of range.

Everyone is holding a 40-meter sword to chop at each other. Life and death are determined by fate and wealth!

But the other person was holding a 40-meter machete, and he was holding a fruit knife. This fight was a bit stupid.

There are many factors that affect the range of the stone cannon, and Zhao Fujin can't figure it out, but there is a simple common sense in physics that Zhao Fujin still understands. When the initial kinetic energy is about the same, the smaller the stone, the farther it will be thrown.

It's just that the stone is too small and the lethality is not enough.

But if the rocks were replaced by iron firecrackers...

Zhao Fujin felt that he had to talk to Shen Qiong again.

The second problem is the problem of city walls.

The city wall in the inner city of Kaifeng is not a big problem. After all, Zhao Da personally supervised the construction. Although the shape is a bit ugly and the construction is a bit winding, it can withstand a beating!

The outer city wall is eighty miles away. To use the professional terminology of later generations, there are only four words: a face-saving project!
Tall is tall, and majestic is truly majestic. The Celestial Dynasty is full of face, but he can't resist beatings!

Half a year later, if the Jin army is fully prepared, pulls up hundreds of stone cannons, and blasts a city wall desperately, it will collapse in a few days. As long as one wall is gone, the outer city of Kaifeng will be completely destroyed.

As for the reason, Zhao Fujin only figured it out after being explained by the City Defense Department Yamen during the court meeting.

When building the outer city wall of Kaifeng, in order to make the wall look good, we directly used bricks to heighten and thicken it, and then sealed the outer layer, and that was it.

But how did Zhao Da strengthen the inner city before?
The outermost layer is the original city wall. Zhao Da stacked a layer of clay with extremely high ductility on the back. After the clay layer, he piled a layer of gravel. After the gravel, he added a layer of clay, and then used bricks to build the outer layer. seal up.

The disadvantage of this is that it looks uneven and unsightly.

But the advantage is also obvious, that is, when the city is attacked, if the stone cannon hits the outer sealing bricks, all the sealing bricks will not break and fall. Some of them will be embedded in the clay layer inside, and when the outer sealing bricks are After the smashing, the stones of the stone cannon hit the clay layer, and many stones will be embedded, which is equivalent to secondary reinforcement.

After this layer of clay is destroyed, a lot of clay will merge with the subsequent layer of gravel, forming a third layer of reinforcement.

Although this kind of city wall is not beautiful, it is durable!

Otherwise, Zhao Da is awesome, he can think of such a method!

Therefore, Zhao Fujin decided that before the Jin army invaded the south for the second time, the outer city wall must be renovated!

As for silver...

Let’s hear what Cai Chi has to say tomorrow!

Early the next morning, Cai Wei was waiting outside Akihito Palace.

Zhao Fujin thought how could this person have such no sense of boundaries!
There was an engagement between the two people. Although eight years have passed since they regretted their marriage and ran away, they still need to pay attention. What's the point of waiting at the door of the palace?

"Then I will send a message to the official family and ask him to wait in the imperial study room?"

Just as Chunxia was about to go out, Zhao Fujin called out: "Forget it, I'm too lazy to go to the imperial study now. You can ask him to come in."

Chun Xia looked at Zhao Fujin who had just woken up, his face had not been washed or brushed, his teeth were not brushed, and his hair was still messy, and he said awkwardly: "How about... my maid does the official's makeup first?"

Zhao Fujin took the face towel handed to him by Chun Xia and washed his face: "No! He doesn't deserve it!"

Chunxia stuck out her tongue, turned around and called Cai Ji to see him.

In the side hall, Zhao Fujin was wearing a white lining and a yellow outer robe. He looked at Cai Ji, who was still looking scrawled, and said with a smile: "See you again in the future, and come back after cleaning up, otherwise the chamberlains in the palace will think that the Liao Kingdom The fleeing people infiltrated into the palace." "Will the officials see me again?"

Cai Wei asked in that half-dead tone.Zhao Fujin choked for a long time and complained in his heart: "Are you pretending to be a prodigal son in love? Eh... rustic!"

"Tell me, let me hear how many skills you have learned from your father over the years?"

Cai Wei's eyes were still dull and his face was dull: "In the past few years, I have not listened to my father's teachings, and I have only been thinking about..."

"Tell me something!" Zhao Fujin was really afraid that Cai Chi would finish what he said. If the last two words were "official", Zhao Fujin would have died!
“Enjoy Yu University!”

Zhao Fujin was stunned: "No more?"

Cai Ji shook his head.

Zhao Fujin was almost furious. He gave him three days and thought he could come up with some refreshing ideas. Unexpectedly, it was Cai Jing's nonsense!
"Haha...that's what your father told the Supreme Emperor back then, right? Your Cai family is really one line of inheritance!"

"I am different from my father. My father only allowed the Supreme Emperor to enjoy Henan University, but I..." Cai Chi paused: "I want the people of Song Dynasty to enjoy Henan University!"

Zhao Fujin was speechless: "You mean, let everyone spend money to enjoy it? Who wouldn't spend it if they have money? The problem is money?"

"The officials can give it to them."

Zhao Fujin finally laughed out of anger and gave Cai Ji a thumbs up: "Talents, you Cai family are all talents!"

"Does the official family have no money?" Cai Chi still had a neutral expression.

"If I have money, why should I look for you?"

"The official can borrow it."

"Borrow it from your Cai family?"

"Our Cai Mansion has been confiscated by the officials..."

Zhao Fujin really didn't want to continue chatting with this fool: "You..."

"But there are too many rich officials in the court. The officials borrow money from them and use the money to build construction projects. After the people have been paid for their work, they will naturally go to eat, drink and have fun. The more people eat, drink and have fun, the more the market will grow. The better, then the government will collect business taxes."

Zhao Fujin was stunned and muttered in his heart: "Fengxiang Yuda means to stimulate consumption and stimulate domestic demand? The three carriages that drive the economy are investment, consumption and foreign trade. That's right. The Liao Kingdom is gone, Xixia is too poor, let alone the Jin Kingdom. Foreign trade is hopeless for the time being, investment and consumption... What this guy said is interesting, it’s just that it’s difficult to get money from the scholar-bureaucrats!”

"Cai Wei, does your Cai family still have money?"

Cai Ji shook his head: "Xiangong Li ransacked everything."

"What about the livelihood of you, No. [-] people in Cai Mansion?"

Cai Chi smiled bitterly: "I can barely survive by eating chaffy vegetables."

Zhao Fujin frowned: "In this case, I will give you some money, and you can use it to repair your Cai Mansion. Let Zhu Meng and Wang Fu live in your Cai Mansion temporarily, and I will help you make a living later."

Cai Ji said sadly: "The Supreme Emperor made a decree before that the three Cai family members will never be officials, so how can they have any livelihood."

Zhao Fujin waved his hand: "Young people, don't always think about entering the court and becoming an official. Wherever you stay, you will contribute to the Song Dynasty. You can also support your family by doing other things. Take off the signboard of your Taishi Mansion and replace it with one……"

Zhao Fujin thought for a moment and said: "Department of Integrity and Education, I will ask all the wealthy officials in the imperial court to receive education. You also charge a fee. It is enough to support the family!"

After Cai Ji left with a confused look on his face, Chunxia asked, "Guanjia, what does this mean?"

Zhao Fujin smiled and said: "Make money!"
