Xiangcheng of Dengzhou and Fangcheng of Tangzhou are now under the jurisdiction of the Dewang Mansion, which more than doubled the expansion of the Nanyang Kingdom, and the border to the north reaches Luyang Pass and Fangcheng Mountain.

Li Yu has been studying maps for a long time.

There is Wuguan in the direction of Chang'an, there is Luyang Pass in the direction of Luoyang, and Fangcheng Mountain passes through Yexian and Xiangcheng to Xuzhou, and finally leads to Kaifeng in Bianzhou, which is the main road to the Central Plains.

Zhu Quanzhong has invaded Jingxiang from here many times, and the top priority is to set up a pass and build a city in Fangcheng Mountain, otherwise this passage will drive straight in, wouldn't it be his own weakness directly for Zhu Quanzhong to pinch?

It's urgent, but it can't be revealed.

He played with his heart.

sent a letter to his father-in-law, Zhao Kuangning.

After telling the family story, let's get to the point.

"There is a hole in the north of Fangcheng Mountain to drive straight into the Central Plains, for the king of Liang to be jealous, the son-in-law thought that the city should be built here to set up a pass, although the project is huge, but the descendants of the blessing, hope that the father-in-law will go to the court and allow the city to be built."

Zhao Kuangning is an old fox, and at a glance, he knew that this was King De who was afraid that Zhu Quanzhong would come to beat him, so he was in a hurry to build a city to guard.

Isn't he afraid? He was also afraid.

At the beginning, Lao Zhu came in from Fangcheng Mountain, and occupied Deng Tang and Sanzhou in a few days, and he didn't even have the ability to resist.

With Fang Chengguan guarding, it would be much better.

Why doesn't anyone set up a city gate in this passage?

Just because this passage is too wide and too flat.

The width of the east and west is fifteen miles, who can build a wall fifteen miles long? Even if you build it, you can't keep it.

Therefore, no one in the past dynasties has built a city here.

The Zhao Kuangning brothers have always been jealous of Zhu Quanzhong and dare not offend too much.

Now that his son-in-law is asking him to come forward to do this, he just doesn't want Zhu Quanzhong to pay attention to him, and he is guilty of this black pot.

As soon as he entered the first month, Zhao Kuangning's recital arrived in Chang'an.

The reason for building the city and placing the customs is very sufficient, for many years Fangcheng Mountain is the main road in and out of the Central Plains, because there is no city to build the customs, resulting in the loss of a large number of tariffs, so that the court's offerings can not be guaranteed, so the Shangshu asked for approval.

Cui Yin is planning to ask Jing Xiang to help recruit soldiers, which happens to be a quid pro quo, besides, whether you build a city or not will take care of my, and it won't cost me money.

Agree.

Of course Li Ye agreed, if the loyal minister wants to do something, can he not support it?

These operations were approved as soon as the Lantern Festival passed.

Li Yufa 30,000 young and strong people in the three cities, digging and burning bricks at the foot of Fangcheng Mountain in the north of Fangcheng.

Five thousand barbarians also took part in the labor.

As soon as February, several large pits were dug at the foot of Fangcheng Mountain. A lot of green bricks were also burned and stacked in the greenhouse.

Think about it, how spectacular the brick-burning movement that 30,000 or 40,000 people participated in.

The Jingxiang Jiedu embassy received a reply from the imperial court, and immediately levied 50,000 young men from various states to build a city under Fangcheng Mountain.

The trees on Fangcheng Mountain were cut down for a while, turning into bare hills.

Li Yu's government officials were so busy that their feet didn't touch the ground.

Transporting grain and building houses provided logistical support, and a vigorous campaign to build cities and build customs was launched in the heavy snow.

Fortunately, at this time, it was just burning bricks, although it was cold, but it was still able to persevere.

Li Yu returned to the palace despite the heavy snow.

"Husband, come and bake the fire on such a cold day."

Xiuniang and Biniang beckoned Li Yu to sit down and roast the fire.

"Wait, I've got a chill on my body, let's get rid of the chill next door before I come over."

Li Yu looked at the two little princesses who were gradually becoming pregnant, and felt happy and guilty at the same time.

I am happy that my child is growing up healthily, and he is happy when he looks at the princess. I feel guilty that I have been busy outside, like a worker bee, and I don't have time to be with them.

Li Yu sat for a cup of tea in the next room, and then changed into civilian clothes and walked into the princess's room.

"Husband, how are the bricks burning?"

Xiuniang was concerned about Li Yu's busy affairs and asked.

"It's burned a lot, but it's still not enough, I'm afraid it will take two or three months."

"Do you need that many bricks?"

Bi Niang has no concept of building a city, but is just curious about the number of green bricks needed.

"Of course. Fifteen miles of closed walls cost at least one million bricks. ”

Hundreds of brick kilns have been built under Fangcheng Mountain.

Tens of thousands of people are cutting down trees to burn charcoal, tens of thousands are digging earth to make billets, and thousands more are responsible for burning bricks.

The whole construction site was crowded and densely packed.

In order to prevent the silver sand thieves from coming to make trouble, the five thousand barbarians have long been ready for battle, as long as they dare to come, they will not let go.

In the first month, the imperial court issued an edict to recruit 5,000 soldiers in Jingxiang to defend the Beijing division.

Zhao Kuangning had to recruit young people in various states and enter Beijing to apply. Because Nanyang was working in a large number of labors, he couldn't respond to the call of the imperial court at all, so he couldn't do it.

In March, heavy snow suddenly fell on Fangcheng Mountain, and the entire Fangcheng Mountain construction site was temporarily suspended.

Li Yu personally inspected the construction site, and nearly 100,000 young and strong cats entered the shack to warm up.

In fact, Li Yu also wanted to build a city with the commonly used Sanhe soil, but it required a lot of yellow rice, where did he get it? People are barely fed, how can there be so much food wasted?

Li Yu: Their plan is to cover bricks and soil.

The castle is made of all bricks, with a layer of green bricks on the outside of the wall, rammed earth on the inside, and green bricks on top of the rammed earth.

This is both strong and saves material.

In mid-March, the weather warms up and the snow melts.

The earth was black and white, and overnight, the light green grass sprouted.

The construction site began to be noisy again.

At noon, there are craftsmen pulling ropes to lay bricks, and the cement used is specially made, which is made of yellow rice mixed with lime clay, which is the formula of Sanhe soil, but the viscosity is higher.

Thousands of masons are working at the same time, and tens of thousands of people are picking up soil and moving bricks, and they are very busy.

I watched the city wall rise little by little.

In the past few days, Li Yu has been on the construction site, although he can't help much, but he is relieved to look at it.

……

Bianzhou Kaifeng Liang Palace.

"What? Zhao Kuangning wants to build a city in Fangcheng Mountain? ”

Lao Zhu's face was extremely ugly.

"The court approved it?"

"Approved."

"Humph! This Cui Yin is really getting more and more disobedient! ”

"What justification did they use?"

"It's said that it's going to be closed and taxed."

"Send scouts to keep a close watch."

"Yes."

"Can you build a city in this winter?"

"Not really, they're burning bricks."

"Hehe, how many bricks are they going to burn?!"

“……”

"Lord, it doesn't matter if they build a city, it's just a mayfly shaking a tree."

"Hmm."

Zhu Quanzhong suppressed the anger in his heart.

What's going on, from the beginning of last year until now, few things have been smooth.

His heart turned, and he thought of a figure, and he couldn't help but feel a move in his heart.

In August last year, his original partner Mrs. Zhang died of illness, although she was sad,

......

Yang Chong was originally an envoy of Jingnan Festival, and was originally Li Maozhen's righteous son, who surrendered to Zhu Quanzhong last year and took his wife as a hostage.

Who knew that Mrs. Zhu Quanzhong died of illness, and he was furious,

Jing Xiang and Li Zhen are both old foxes, pretending not to see it, no one is talking about this kind of thing, and Zhu Quanzhong's obscenity is even better.

Zhu Quanzhong thought about it, too, even if Zhao Kuangning built a city in Fangcheng Mountain, it would be useless. Jing Xiang is like a colander, full of holes, can you still plug it?!

To say that there is reincarnation in the Heavenly Dao, Yang Chongben suddenly received a letter.

The letter was written by his wife.

scolded Yang Chongben in the letter.

said that you are a dignified festival envoy, and you can't even protect your own wife, so you let other men sleep.

"I'm already Zhu Quanzhong's woman now!"

Ahh

Yang Chongben spurted out a mouthful of blood.

He fainted on the spot.

When I woke up, I cried loudly.

Yang Chongben wrote a letter to Li Maozhen, admitting his mistake, wanting to change back to his original name, and calling him Li Jihui, and he wanted to take revenge against Zhu.

immediately beheaded the prison army sent by Zhu Quanzhong, and united with Li Maozhen to oppose Zhu.

Li Yu knew that these things would happen, although it was beneficial to him, but he was too far away from him, and what he was most anxious about now was to build a city.

More than ten days, day and night construction.

The exterior wall was half built, and the brick wall was plywood, and tens of thousands of people were rammed earth inside, and the sound of trumpets was deafening.

April is full of spring.

There is a crowd of people at the foot of Fangcheng Mountain.

Zhao Kuangning requisitioned another batch of young men to replace the original labor.

The first to be built was Sekijo.

The city is six feet high, and there is an urn city built in the city gate.

The city wall is six feet wide and can be used for sports cars.

As the rammed earth of the city wall was raised little by little, the brick walls in the city wall began to be built, and plywood was also put up, and the missing areas were re-compacted by filling the earth.

The wall is closed and a cave is built every fifty zhang.

The cave is connected to the wall, and there are stairs to step on the wall.

There are stove rooms and warehouses in the Tibetan Soldier Cave, which can be stationed in the Tibetan Soldier Cave for a long time.

The whole wall excludes the gate urn city in the middle, and there are sixteen hidden soldiers on both sides.

Fifty zhang behind the Tibetan soldier cave correspondingly built with granaries, arsenals, barracks, wells and other facilities, and the middle is paved with bricks and stone corridors to connect.

A discerning person in this fortress knew at a glance that this was a precaution against the enemy in the north, and there was no fence in the south.

Spring ploughing is coming up in April.

In the middle of the year, after completing most of the project, Li Yu put most of the young people back to farm, and the remaining 10,000 people continued to finish.

Five thousand brute soldiers are now in full swing to put the finishing touches on it.

Cutting wood from the mountains and putting a wooden fence behind the wall is a simple protection.

Zhao Kuangning also sent 5,000 elite soldiers to assist in guarding Fangchengguan.

This castle, which has never been seen in history, appeared in this way.

Just when Li Yu let out a long breath and was finally about to finish, there was a report from Tanmalay.

"Report to the lord, the silver sand thief is here!"
