He sent Zhao Zhen away and a large number of senior officials of the court.

Until now, Wang Ning'an can finally enjoy the taste of being the only one.

The land of Qizhou, millions of living beings, life, death, good and bad are all in his thoughts. This feeling is great, very good, and of course it is also very stressful.

Wang Ning'an just took a brief break and sorted out his ideas. He called Ouyang Xiu and Zhao Zongjing over, and several generals also arrived.

"There are many things at the moment, which are very messy, but in the end, there are two things. One is to solve the problem of being beaten. Yelu Hongji's defeat and withdraw from the Great Wall, but he was not willing to fail. In the past few months, he has taken over his old subordinates, restored his strength, and changed his strategy, sent a small group of cavalry to frequently invade and rob and kill, which is very troublesome."

Speaking of this, Murong Qingchen took it, "Sir, as you see from a humble position, Yelu Hongji at this time was even more terrible than before. He lost Youzhou and cut off one arm of the Liao Kingdom, but the shackles on this arm were also broken. From now on, it will be very difficult to fight against Yelu Hongji's main force. On the contrary, it will continue to be plagued. Just like the Qin, Han, Sui and Tang dynasties, we must adjust our strategies and can no longer deal with the old methods."

Murong Qingchen, a guy who is not only careless with Wang Ning'an, has a gangster's moral character. When facing others, he is serious, doesn't drink much, and is even more lustful, and is a piece of iron!

But this guy is meticulous and good at thinking and explains the situation thoroughly.

The Sixteen Prefectures of Yanyun are the pain of the Han family. Which Han doesn’t want to restore Yanyun?

From another perspective, with the Sixteen Prefectures of Yanyun, the Khitans had to stop their nomadic steps and become a semi-agricultural and semi-animal Husbandry.

On the grassland, if you can beat it, if you can, you can run away. Anyway, the world is wandering around, and no matter how many troops the Central Plains dynasty sent, they can't do anything to them.

This is the advantage of nomadic peoples!

After the more than 16 states of Yanyun, the Khitans could not be so free and comfortable, and they would be able to advance and retreat freely. They also had to defend the city like Han people.

After Zhao Er made two northern expeditions, the Liao Kingdom had to concentrate its army and fight desperately in Youzhou and the Song Dynasty.

Of course, Zhao Er was not lucky and ended with a crushing defeat.

When he arrived at his grandson, Wang Ning'an assisted him, Zhao Zhen took back Youzhou by chance. Of course, it was an unprecedented victory for the Song Dynasty and worth boasting about it.

But Murong Qingchen was right. It must be seen that after losing the bonds of Youzhou, the Khitans quickly restored their ancestors. They broke into pieces and went out together, constantly raiding the Great Wall. They were unscrupulous and came whatever they wanted.

On the other hand, the Song Dynasty had to guard the territory and protect the people.

There are not many choices, so I can only fight to the end with the Liao soldiers.

I was trembling and couldn't sleep at night.

Fortunately, in the Battle of Shunzhou, the Song army fought a great reputation, especially the Wang family's iron cavalry, which was a nightmare for the Khitans. They did not dare to invade in large quantities, and Youzhou was in a delicate balance.

"In the past, the Song Dynasty was mainly to prevent large-scale invasions against the Liao Dynasty, so we built a majestic city, hoarded people, and put on a stance of fighting... But from then on, we must arrange defense lines more widely, establish an intelligence warning system, and prepare a capable field army to support all parties at any time. In short, we must adjust our strategy!" Murong Qingchen said decisively.

His speech was unanimously supported by everyone, including Yang Wenguang, who came from Juyongguan, who also nodded frequently and was very satisfied.

"God blesses the Song Dynasty, and many good generals emerge. Even if we old people retreat, we don't have to worry about no successors."

According to Murong Qingchen's suggestion, everyone actively discussed and finally came up with a set of strategies.

It is divided into two parts, first of all, the army is integrated.

After the Wang family's iron cavalry showed their power, Zhao Zhen imitated the Wang family's iron cavalry and formed 3,000 heavy cavalry to protect him, and Yang Wenguang was in charge of the command.

Zhao Zhen went to Luoyang for inspection and took away 20,000 Japanese troops and 3,000 heavy cavalry.

There are still 3,000 heavy cavalry of the Wang family, nearly 20,000 light cavalry, and 100,000 infantrymen left in Youzhou. Behind them are the huge Hebei Legion and many wing troops.

Obviously, the current troop allocation is to fight the main force of the Liao army, with infantry as the main and cavalry as the auxiliary.

After the adjustment, the Wang family's 3,000 heavy cavalry were divided into three thousand-man teams, commanded by Liang Dagang, Li Wuji, and Wang Ningxuan, and divided into three sides left, center and right to deal with the invasion of the Liao army.

Under the heavy cavalry, the light cavalry also made adjustments and stationed in various states to strengthen vigilance.

...

Finally, there is the infantry group.

"This is the second part of our rectification. We need to rebuild the Great Wall. We set up a beacon tower every three miles, a pier every five miles, and a fort every ten miles. In this way, we will send infantry guards. As long as the Liao soldiers appear, we will immediately ignite the beacon fire and the entire army is on guard. The military, civilians and the people must retreat into the castle and guard them strictly. Each fort must accommodate at least 3,000 people, of which 500 soldiers can be fought. Relying on the city, it can withstand the attacks of 5,000 Liao soldiers, and it must be able to defend for one to two days, and buy time for reinforcements."

Murong Qingchen was very clear and attracted everyone's praise. He could really follow what he said, the line of the Great Wall would be as solid as a rock and no one would ever want to break it.

But Murong Qingchen spread his hands, "It's probably not easy to do this."

Zhao Zongjing said curiously: "Why?"

"The Liao soldiers will not let us do our wish." Murong Qingchen said helplessly: "It is not a small project to build so many Duntai castles. If the Liao soldiers invade from time to time and harasse and destroy it, I really don't know when it will be repaired!"

Zhao Zongjing was silent for a long time, and suddenly screamed, "Don't you know what you are talking about so lively? Is there any way you can deal with the Liao soldiers?"

Murong Qingchen's face turned red, "Little Prince, if you want to prevent the Liao soldiers from raiding, you must first destroy their main force before you can build the city with peace of mind. This was what Qin Shihuang did back then, first defeating the main force of the Huns, and then let General Meng Tian build the Great Wall and guard against the Huns."

Liu Yu said: "Brother Murong, I understand it correctly. Do you mean that you have to defeat the main force of Liao Kingdom to build the Great Wall? But the question is, if we have the ability to defeat the main force of Liao soldiers, why do we still build the Great Wall? Let's just go into the grassland and destroy the Liao Kingdom!"

Murong Qingchen also asked back: "You said lightly. Can we work hard on the expedition now? Yelu Hongji doesn't have to fight with us. As long as he keeps attacking our food route, he will be enough to defeat us."

After all, this matter turned out to be a dead end.

To build the Great Wall, it is to deal with the Liao soldiers. However, if you want to successfully build the Great Wall, you must first eliminate the interference of the Liao soldiers and destroy the main force of the Liao Kingdom. However, now building the Great Wall and defending the Great Wall are not able to deal with the Liao soldiers, let alone destroy the main force of the Liao Kingdom...

Everyone's last eyes fell on Wang Ning'an, and they thought to themselves, Lord Wang, you make a decision for us!

Wang Ning'an is so angry. You bastards will know to look for me when they encounter something. So who should I look for? Wang Ning'an thought for a long time and suddenly saw Ouyang Xiu, and his eyes lit up.

"I said Zhuiweng, how did that thing be studied?"

Ouyang Xiu was still confused, "What's the thing?"

Wang Ning'an was even worse. "A few years ago, didn't we ask the Baigong Academy to study new waterproof building materials, mainly to deal with the Yellow River floods and build dams? Have they achieved any results?"

Ouyang Xiu's face turned red, saying, "Is this? You still have to ask Su Song, after all, I'm not good at..."

Obviously, in order to solve the problem of the Great Wall construction period and the harassment of the Liao soldiers, there is only one way, that is, to cause it quickly and not give the Liao soldiers time to react.

However, it takes time to use the previous building materials, grinding stones, burning bricks, mixing glutinous rice and egg whites to make adhesives, and build a small fort. It will not be completed in a few months. And it will take time to wait until the city wall is completely dry before it can be solid.

After such a long time, the Liao soldiers were enough to kill several rounds.

However, if there is cement, the construction period can be greatly shortened. Before the Liao soldiers can react, the Song Dynasty built a solid castle to defend against the enemy boldly.

The only problem... is that in a thousand years, people will squeeze on the Great Wall of Cement. No matter how they think about it, they will smell like destroying cultural relics and historical sites... But Wang Ning'an has made up his mind and it doesn't matter if he is criticized. He wants to write Su Song immediately. If he hasn't made the cement yet, Wang Ning'an will personally get into it.

So many time travel seniors have succeeded, there is no reason why I can’t do it!

...

Wang Ning'an was worried, and there were also people in Luoyang who were worried, that was Wen Yanbo and Wen Gong. He was also responsible for the project of building a new capital.

The most important one is the imperial palace, which is listed as a top priority.

Wen Yanbo was very experienced. He was determined to command the wood, bricks and tiles needed quickly prepared.

But just after the beginning, something happened in front of me.

Kaifeng Palace had to be abandoned because it used lead pipes.

The Luoyang Royal Palace can’t use lead pipes, so what should I use?

Iron pipe?

It soon became rotten.

Copper tube?

Not bad, the cost is too high, and the copper will rust.

Stone?

This is a good choice, but after the experiment, Wen Yanbo shook his head. If a complete stone is hollowed out in the middle and made into a water pipe, it will be too difficult. If you are not careful, the stone will break and the speed is outrageously slow.

What if two halves of stones are used to make a water pipe?

The mud and water outside will seep into the pipe along the gaps, and it will be blocked in no time.

I thought about it, the heavy rain was pouring, the sewer was blocked, and the palace became an invincible sea view room, which would be lively. If the emperor gets angry, there will be no people rolling around!

Wen Yanbo finally understood, no wonder his predecessors used lead pipes to drain water!

Maybe it’s not just a bad thing, but a forced one.

When Zhao Zhen arrived, he first went to investigate the progress of the palace. Wen Yanbo's face turned red and he didn't get ready to go to the water. How could he build the palace above? Therefore, the huge construction site was in a mess.

"Your Majesty, the old minister thinks that you can continue to use lead pipes and can be buried deep..."

Before he could finish his words, Zhao Zhen looked like he was eating people, and shook his sleeves and angrily shouted: "Mr. Wen, I have lost so many children. Do you think I am not dead enough? If anyone dares to lift the lead pipe with me again, he will be killed without mercy!"

His Majesty the Emperor disliked the lead pipe and had become a pathological persistence. He angrily said: "The materials must be safe, the progress must not be delayed, and the national law will be used to serve you!"

After saying that, Zhao Zhen turned around and left, leaving Lao Wen aside.

Sure enough, credit is not easy to make!

Wen Yanbo's facial features were so worried that he shrank into a bun, and he felt wronged. After winning the battle, the emperor became more and more difficult to serve. If he couldn't use a lead pipe, he would have to use a magic horse?
