It is also a treatment method. After repairing, it will not be maintained, because the silt and sand of Jingshui will still be like the old canals before, and will gradually be blocked by the sedimented silt and sand. Especially Zheng Lang knew in his heart that the environment in Shaanxi was getting worse and worse.

Such a long new canal, coupled with many small flood discharge gates and large Chengchi ponds and water diversion weirs, make Sanbai Canal an extremely huge water conservancy project.

The court first sent Zhou Qi, a Ph.D. in Taichang, to preside over water conservancy, but his ability was insufficient. Zheng Lang went to Beijing to propose to transfer Ye Qingchen from Jiangning. He had a good relationship with Song Xiang and Zheng Jian, and was also taken down by Lu Yijian and went to the prefect of Jiangning.

Zheng Lang remembered that he did something, not only did he achieve water conservancy in Liangzhe, but later when he came to Yongxing Army, he made great contributions to dredging Sanbai Canals, which changed the irrigated arable land from 2,000 hectares to 6,000 hectares. This was the first large-scale construction of Sanbai Canals in the Song Dynasty, and the cost was not much.

I was in Jiangning and just came. I saw many problems. I sent someone to ask Fan Zhongyan and Zheng Lang to discuss and work together.

Ye Qingchen ignored whether Zheng Lang and Fan Zhongyan would be very hard. The four major players in the court had different political propositions and military concepts, but they had one common feature: they were very diligent in the northwest, went to the countryside, and had almost no time to rest. Some ministers in the court joked that they were the four iron men on the edge.

It is not a flesh-and-blooded **, but a steel-building **.

Zheng Lang had no choice but to go.

Once repaired, there will be more than 30,000 hectares of plowing fields.

Perhaps the output is less than the total output of Taipingzhou, but this is in Shaanxi, which is a serious shortage of food.

As long as the three are done and the military farms from all walks of life are basically self-sufficient, it will save the imperial court a lot of money. Its significance is far more important than the development of Taipingzhou.

Zheng Ping opened his hand and said, "Dad, I want to go too."

"Don't mess around, Daddy is going to do business." Cui Xian shouted.

"Don't scare the child." Zheng Lang stretched out his hand and hugged Zheng Ping in his arms, saying, "Dad takes you there."

My daughter is old, she can walk, speak, and has some wisdom to keep her by her side without any trouble.

"This is not how I teach my children."

"The child's young makes her have a wonderful childhood..." Zheng Lang smiled, hugged Zheng Ping and put on Xiaoqing's back, and Zheng Hang cried behind him. The little daughter didn't dare to take it, so she comforted her. Regardless of whether Zheng Hang understood it or not, she would leave Weizhou.

Another drizzling summer rain.

The willows after the rain were fresh and charming. The three of them sat in the teahouse while drinking tea while talking about their important things.

In terms of water conservancy management alone, these three people were the top water conservancy experts in the Song Dynasty. Ye Fan and the other two said many reasonable ideas, and Zheng Lang added them one by one. The details are similar, each with their own beauty, but in the long run, Zheng Lang's ideas are still a little longer.

It has nothing to do with wisdom, it is later historical knowledge.

Just now, Jingshui is difficult to cure. Jingshui has a stone of stone and several buckets of mud. However, this kind of silt can be dug to crush alkaline fertilizer fields and damage to water and soil, resulting in salinization of many arable land in Guanzhong.

Therefore, around the Sanbai Canal, Zheng Lang and Fan Zhongyan built an idea, focusing on the new canal, and constructing it with the old canal. Before constructing it, they first close the channel, dig out the silt from the channel, press the alkaline fertilizer fields, and then repair the dock gate and the sluice gate to drain the canal water, and re-irrigate the surrounding fields.

After years of accumulation, new canals can be replaced through old canals, blocked the new canals, re-digged, and seized fields with mud. It seems to be a good idea, but the cost is even higher.

There was not much technical problem. The Doumen Shui Gate Technology of the Song Dynasty was far better than that of the Tang Dynasty. As for some rocky places where the new canal passed, gunpowder was also provided with more convenience. As long as the funds were sufficient, it was not a problem.

Once completed, it can be a model. In addition to the Yejing River Basin in Shaanxi, the Guanzhong water conservancy system has always been composed of the Jing Canal System with Jing Water as the water source, the Wei River as the water source, and the Luo River as the water source.

These are the three major canal systems of the Western Han Dynasty.

The prosperous times of the Western Han Dynasty cannot be restored, but part of it can be restored.

Once the three major canal systems are formed, Shaanxi will no longer worry about using grain.

But Zheng Lang was very suspicious.

The root cause is not the canal system, but the most severe damage is nomadicism, and farming also causes damage. This deterioration is not only in Shaanxi itself, but also in the territory of Qinghai, Gansu, Tubo, and Xixia. It all deteriorates in the territory of water and soil, which in turn affects Shaanxi and even the middle and lower reaches of the Yellow River.

Afforestation is still a treatment for symptoms and cannot be cured.

Zheng Lang talked about this with Zhao Zhen many years ago, but he didn't know how to solve it.

Helplessly, I talked about the importance of forest planting again.

As the sky gradually became late, large clouds of rain rose, and the green mountains in the distance were covered with clouds, floating like a fairyland.

The three of them made the general direction and had to go to the on-site observation tomorrow for the specific details.

Ye Qingchen's attitude was very serious.

This also made Zheng Lang appreciate it.

After talking about the serious matter, he talked about his affairs. Fan Zhongyan asked suspiciously: "Xingzhi, are you still planning to lay off troops?"

"Yes." Zheng Lang replied. In the battles between Shimenchuan, many soldiers were sacrificed by Jingyuan Road, but Zheng Lang's purpose remained unchanged and continued to lay off troops. After that, more than 7,000 soldiers were transferred to Sanbaiqu to build the canal, and it was this group of troops that were cut off.

"Is the defense of Jingyuan Road enough?" Fan Zhongyan was very worried.

With the two disarmament, coupled with the previous disarmament, and the sacrificed soldiers, Jingyuan Road will lose more than 18,000 people.

The overall combat effectiveness has not decreased, and all those left are elite soldiers who can fight and kill. Moreover, because 25,000 cavalrymen joined, their combat effectiveness has not decreased but increased.

But this combat power refers to the combat power during combat, not the combat power of defense. Those cavalry used for defense are similar to infantry.

"Brother Xiwen, don't worry..." Zheng Lang said his plan. Whether it is Fan Zhongyan or Ye Qingchen, don't worry Decao.

"Is there any area to defend?" Fan Zhongyan was stunned.

"It was extended from the Tang Dynasty's policy of blocking roads to prevent people from moving. But Brother Xiwen, if I'm not wrong, Yuan Hao still has a battle. Before that, Brother Xiwen should not use this policy on Huanqing Road, so as not to alarm the enemy."

"Ge Huailong..."

"Brother Xiwen, you guessed it right. He was the one who deliberately stayed on Jingyuan Road. Helplessly, I didn't dare to attack Xixia rashly. I could only use some methods to lead the Xixia army to Jingyuan Road for battle."

"Many soldiers will be sacrificed again..." Fan Zhongyan sighed.

"Brother Xiwen, Xixia is immortal. The soldiers who die in the future are not only now, but also don't know how many soldiers will die, and how many families will be separated. When I returned from Shimenchuan and my wife and daughter went out of the city to greet me, I was also sighing in my heart, I came back alive, and the family was reunited, and I was happy, but what about the families who sacrificed their soldiers? Although it was painful, I had to do it."

Fan Zhongyan advised Han Qi that there was a reason for him. Whether Yuan Hao had proclaimed himself emperor or not, it was actually a fact that this could not be changed.

As long as you make good defensive measures to prevent him from attacking, no matter whether he is called emperor or not, then the war will be reduced and many people will die. This is the representative idea of ​​passive defense. What should I do when I open the border? The poverty of the border is, the court will get it. The larger the border is, the more expenditure it spends, the more defense scope will increase, and the more troops will be stationed.

But that's not the case?

The Xixia has not been eliminated. As long as it is eliminated and there is no huge force, will the imperial court need to station so many soldiers in Shaanxi?

Perhaps there were turmoils in the foreign tribes, but there were only disadvantages? In the northwest, there were pastures and ranches, there were war horses. Before the age of hot weapons, the age of cold weapons, the cavalry was still the sharpest military branch.

Some of the foreign tribes have rebelled at times, but most of the foreign tribes have been properly governed and used by the court, which can provide more military sources for the court.

At the beginning of the founding of the Northern Song Dynasty, the powerful foreign soldiers were not aware of the power of the foreign soldiers.

As long as it is used properly, how could the foreign soldiers in front of Kunnan Pass in Lingnan have shown their power? Can't they be used to deal with the Khitans?

Besides, as Fan Zhongyan wished, Xixia really would not attack the Song Dynasty? Huanqing Road and Yanshan Road were convenient for terrain, but what about Fulin, Jingyuan, or even Lanhui?

What does this have to do with opening the edge?

Fan Zhongyan sighed and said, "I'm afraid it's not easy. At that time, Li Jiqian was only in the five states of Yinxia, ​​and the court could do nothing, let alone the Hao thief was like this."

"You can take it slowly."

"Where is the court's finance?"

This is Fan Zhongyan's attempt to conquer Zheng Lang and make him give up the idea of ​​"radical".

Sure enough, Zheng Lang shook his head and smiled bitterly, "Brother Xiwen, I will talk about military affairs first. First, the four people on the edge have their own strengths and weaknesses. First, I am a little unintentional to make progress."

Fan Zhongyan and Ye Qingchen were stunned.

Zheng Lang is right.

If you have a far-reaching vision, who can match him? All the disadvantages of the Song Dynasty, the subsequent gains and losses, and the direction of history are all in his mind.

He is also doing it, doing it very carefully. In the clear world, he uses the new doctrine of the mean, and does not want to cause trouble. He promotes it bit by bit, so that everyone can see and hear it, and then reflect on it, so that they can change their ideas one by one.

In fact, I am still afraid of trouble and controversy, and I am not decisive.

If he fights according to his actions, even if he is in power as prime minister, he may not be able to reverse all the disadvantages of the Song Dynasty one by one in his life. There are benefits, and although there are controversies, there are still not many.

This is also caused by his faint personality in his bones.

But outsiders couldn't see that he had done many things, some of which were very controversial.

Is this the case? What is this the later reform with Wang Anshi?

Zheng Lang did not explain and continued: "Brother Xiwen and Brother Zhigui, Brother Chun, each has their own strengths. For example, military affairs, Brother Xiwen and Brother Chun value military generals and promote talents, but they are conservative and unspeakable, and some are not enterprising. Brother Zhigui is enterprising, but he is too radical and despises some talented generals, which leads to the mistakes of the strategies one after another. Our dynasty values ​​literature and clever military forces, and has a positive side to prevent the separatist vassal states and the situation of the Five Dynasties and the Ten Kingdoms. But if the country declines, the whole country will die. It is too much to correct the mistakes. Brother Xiwen and Brother Chun value military generals, and only love talents, how many times have they sought suggestions from military generals? Zong Shiheng was in my hands. Whenever there was a war, he would be the first to ask for good strategies. Brother Xiwen asked the court to be transferred to Huanzhou, how many times have he asked?"

Fan Zhongyan did not answer.

Zheng Lang was right or wrong. He asked, and he was also using it, including national comfort. Fan Zhongyan often used his people to strode the monks.

But his military theory is defense, rather than taking the initiative to launch an attack, or deliberately leaving a vacant position like Zheng Lang, luring Yuanhao into invasion in order to seek a fighter opportunity, and what do he need to discuss with the old generation?

Zheng Lang also knew that he could not convince Fan Zhongyan, and said, "Why does the country need money?"

"Take it from the people and use it for the people."

"I see that since the founding of my dynasty, although my wealth was several times that of the previous dynasty, I have not seen the court implementing a policy of light taxes and low taxes. Where is this money used?"

"Oh," Fan Zhongyan sighed.

Zheng Lang has already begun to remind him in kindness.

There were many contradictions in the Song Dynasty, especially the inspiration of this war, which revealed these contradictions one by one. Therefore, the Qingli New Policy was introduced.

The infinite exaggeration of history books, why did it not succeed in the end? Some people say that Zhao Zhen did not cooperate, some people say that the gentleman party is too resentful and does not have unity, and some people say that the Conservative party is strong, and this is not the root cause.

Zhao Zhen has realized some problems.

Although the Conservative Party was strong, Lu Yijian was seriously ill. He did not play much role in the Qingli New Deal. The counterattacks by some ministers, including Xia Qiu, were just party struggles and countering the suppression of gentlemen. The finger was not directed at the New Deal itself.
