Chang'an is located on the banks of the Weishui River, and to be honest, this generation does not have much favorable terrain to support. The terrain is flat, there are no big rivers, and there are no mountains, if you want to stick to Chang'an, you really don't need to work hard outside the city.

Liu Fa is also like this, he is mobilizing the whole city, only strengthening and blessing the city. In the hot weather, the soldiers stood on the head of the city and waited for it, even if the Liangshan army outside did not show the slightest sign of attacking the city, they wore armor and waited for the battle. The sun is blazing, and it can always dry the battlements hot, let alone dark armor.

Song Jun just stood like this, all the time, waiting for him.

On the city wall, which was more than three zhang wide, the Song army and countless Ding Zhuang in the city were busy carrying arrows, wood, stones, fire oil and other things. On the horse's face, the bow of the divine arm and the crossbow of the bed are lined up, and the crossbowmen are making post-mortem inspections to ensure that the instruments are in good condition.

And unlike the noise and noise at the head of the city, the city seems to be in order. The government demolished a large number of houses, but also resettled the people one after another, and the various materials that remained after the demolition were either used to defend the city or build a breastwork. Unrestrained is inside and outside the city. Those large open spaces were equipped with hundreds of artillery trucks of various colors. Although they all know that Liang Shanjun's stone cannon is good, they can't just rely on the opponent to bombard, right?

The people in the city took the fang as a unit, led by the baozheng of each fang, and organized the young and strong to assist the defenders in carrying equipment and transporting materials. In addition, fire prevention, moisture prevention, patrol, etc.

Everyone up and down was busy with their feet in the sky, but the morale of the people in the city was not high. Helplessly, this war did not benefit them, the Song army just fled, and the Liangshan army that entered the city would not burn and loot. What's more, in recent times, the prices in the city have skyrocketed, especially food and salt, which have skyrocketed. If so, the war would be a burden for them.

The soldiers are together, not to mention the deaths and injuries of the people in the city, but only to say that the damage to Chang'an City is irreparable.

And it was in this situation that Liu Fa ushered in another leap in his official position, from the six-way economic envoy to the official Shaanxi Xuanfu envoy, promoted to Chongxin and Zhenning Army, and added the school Taifu.

Liu Fa was originally the envoy of the Loyal Army, and now he is the envoy of the two towns of Jin, which can be said to be a great honor, and there is also the master of the school. This is more glorious and great glory than the privy envoy and the captain.

Lu Qian received a letter from the city the next day, and looking at the Song family's kindness to Liu Fa, he not only remembered Paulus, but also Friedrich Wilhelm Ernst Paulus, the commander-in-chief of the Sixth Army of the Third Reich, and the marshal who did not get the marshal's scepter.

Zhao Ji must be very similar to Hitler at that time at this moment, and he very much hopes that Liu Fa can stick to the end, and he very much hopes that Liu Fa will be his great loyal minister.

Because it is impossible for him to draw troops from the Jiangnan battlefield, which is in a good situation, to return to Kansai.

Now all he can count on is Liu Fa, hoping that Liu Fa can keep Chang'an for him, so as to give Kansai a glimmer of hope.

The time is already mid-May, and the Liangshan army in Guanzhong can be said to be gathered in one place. From Heluo, from Tongzhou, from Yan'an......

The gathering of more than 100,000 troops is really overwhelming.

In Chang'an County, Chang'an City, Wannian County, more than 20 military villages were built on all sides, and the city was locked inside. At this time, Chang'an was not the Chang'an that later generations could see, nor was it the Chang'an City of the Sui and Tang Dynasties in history, but only the imperial city of the Tang Dynasty. The warlord melee at the end of the Tang Dynasty had greatly changed the appearance of Chang'an in the Sui and Tang dynasties. The east and west cities of the outer city are the county seat of Chang'an and the county seat of Wannian.

Then the Liangshan army was not in a hurry to attack, and Li Mida had been operating in Chang'an City for a long time, but the time had not yet arrived. And many siege equipment still need time to be transferred from the rear or made locally.

One of the biggest inconveniences in this place is transportation. Don't look at a Weishui running through the east and west, but such a famous Weishui, it is not navigable by boat.

As early as the Spring and Autumn Period, there was a famous 'Battle of Rafting' in the annals of history, and when Chu and Han fought for hegemony, Weishui was the lifeblood of the transportation of grain and grass for the Han army. In the Han and Tang dynasties, the grain and grass of Chang'an were transferred from Luoyang, and there were many tens of thousands of stones every year, which was amazing.

However, from the middle and late Tang Dynasty, Weishui River Transportation was like the rivers and mountains of the Tang Dynasty, the rivers were declining day by day, and the decline was irreversible.

"My lord, there are three reasons for the decline of this Weishui River Transport. One is that there is less water, the second is more sand, and the third is that the difference between the amount of water in the flood period and the dry season is too large. "Xu Guanzhong is a living map, and he knows Guanzhong well.

At this moment, he said to Lu Qian: "The northwest is already dry, and there are few Weishui tributaries. And the Song and Xia battles, many places did not encounter military disasters, but there was no grass, and there were no big trees. In the words of the king, the vegetation has been destroyed, the soil erosion is heavy, the sediment content of the river water is sedimentary, the river body is of course getting shallower and shallower, and the beach is silted up, which naturally hinders navigation. ”

"In addition, the 800-mile Qinchuan River, with many living houses and extensive arable land, all need irrigation water. Chang'an is a place where the capital has been built for a long time, and the primary factor in consolidating the power of the successive dynasties is to prevent food problems in the capital. In this way, the agricultural production in this Guanzhong area is closely related to the food supply of the capital, which makes the emperors of the previous dynasties who built the capital here must be actively concerned about this. Historically, Guanzhong water conservancy was carried out quite early and has achieved remarkable results. Qin opened the Zheng Canal, irrigated 40,000 hectares of fields, Han opened the White Canal, re-irrigated more than 4,500 hectares, and these two canals alone are more than 44,500 hectares. Other canals are even more incalculable. Such a large number of acres of irrigation water is also a major cause and effect of the consumption of water in the Wei River and its tributaries. ”

Then Xu Guanzhong dropped the book bag to Lu Qian, "Wang Mang's great Sima Zhang Rong has pointed out, "Hanshu Gou Xun Zhi" contains his words: Now the western counties and even the Jingshi (Chang'an) eastward, the people are leading the river, Weishan River water irrigation, spring and summer are dry, when there is little water, so the river is late, silt and slightly shallow, rain and water, then overflow. …… If you don't have to irrigate, then all rivers will be popular, and the waterways will be self-beneficial, and there will be no harm from overflow. That is to say, Zhang Rong pointed out that the water used for agricultural irrigation in Guanzhong has made the river silt up and shallow, and as a result, it is easy to cause overflow, which has an impact on the river and will inevitably restrict shipping, but it is necessary to use the method of abolishing irrigation to solve the problem of water transportation and river channels. But this will not work, of course. Therefore, Zhang Rong's suggestion was naturally not implemented. Even if Wang Mang is really a traverser, he is only afraid of the knowledge of the red soldiers. In order to maintain the passage of Weishui, it is too scary to reduce the arable land around the capital.

"Finally, there's urban water. Han, Sui, Tang built the capital of Chang'an, the ancient capital of Chang'an lasted the longest, the capital has always been the place where the population is concentrated, and then the residence of the emperor and the generals, in order to meet the water source of the pond in the garden of the emperor's palace and the nobles, in order to solve the water supply problem of the majority of residents. Han Chang'an City mainly put Jiao, Wei (泬) convergence to Kunming Pond, Kunming Pond lower mouth is divided into three factions to introduce the city, Sui and Tang Chang'an City is the east of Ba, Chan, west of Wei, Jiao, is also divided into three canals into the city, these underwater flows are originally flowing into the Wei River. ”

Lu Qianren is not under Chang'an City, he is in Xianyang on the other side of Weishui at this moment.

Looking at the map of Guanzhong in front of him, how could he not know what Xu Guanzhong meant. In the Zhao and Song dynasties, Chang'an was no longer the capital, but the pressure and burden on agriculture in the Guanzhong region were not inferior to those of the Han and Tang dynasties, and the reason was only the Western Army.

The supply of food, grass and materials for hundreds of thousands of Western troops, even if the burden is not all on their shoulders, it will also make the people of Guanzhong breathless.

This agricultural water is only a lot more than that of the Han and Tang Dynasties.

Xu Guanzhong just told Lu Qian that it was whimsical to want to restore the Weishui River Transport.

The destruction of vegetation in Guanzhong by the Song-Xia War was only higher than that of the warlords at the end of the Tang Dynasty, and the consequences were disastrous to understand in Lu Qian's words, and I don't know how long it would take to make up for it.

Coupled with the development of agriculture in Guanzhong, Weishui is already difficult to return.

However, it was not only the Northern Song Dynasty that garrisoned the army in the west, Lu Qian still wanted to do this. It's just that the Western Army of Zhao and Song Dynasty is attacking on defense, but Lu Qian is bent on opening up thousands of miles.

"So, you still have to open a canal?" As Lu Qian spoke, he picked up a book of folds on his desk.

This is Sun Zhaoyuan's sparseness.

Lu Qian has not been able to win Guanzhong yet, but he is already starting to govern Guanzhong. In order to manage Guanzhong well, one of the major root causes lies in transportation.

Since Renzong had to defend against Western Xia, Shaanxi was stationed with heavy troops, and the grain depended on the southeast, and millions of stone grain and rice arrived every year. However, the water transport of the Wei River can only be used to transport bamboo and wood in the Qinling Mountains of Guanzhong, and the rafts are decentralized. That is to say, from Luokou to the west, the transportation of military baggage is all land transportation. In this way, with the cost of vehicle transportation, half of the grain and rice of one stone were gone first, and it was a lot of money for the people of Guanzhong to transport grain.

"It's not impossible to open the canal, when the water in Guanzhong is muddy, can it be navigable all year round?" For example, the channels in history will inevitably impact and fill the silt when the summer rain comes. The tributaries of the Weishui River, which are intertwined with the Cao Canal, leave behind countless sediments every time the water level rises sharply. If it is not repaired in three or two years, the canal can be destroyed by three or five percent, and then it will be played directly in three or five years.

This is called Xu Guanzhong's difficulty. He is a living map, but he is not a water expert. In the matter of controlling water, it is seven tricks and six tricks - none of them. Lu Qian's question, he couldn't answer it. And Sun Zhaoyuan's Shangshu also didn't mention this.

Lu Qian immediately summoned Huang Qianshan, "Take Sun Zhaoyuan as the positive, and you as the auxiliary." For three months, I visited the site, carefully studied the evidence, and came up with a feasible program. "Is this guy careful?

Huang Qianshan was overjoyed, and it was naturally easy to stay by Lu Qian's side and pat his ass, but this was no credit. And now, he is finally looking forward to the real difference. "Wechen dares not to do his best. will assist Sun Xianggong, fulfill his duties, and live up to the king's high expectations. ”

Since Sun Zhaoyuan proposed so, Lu Qian dared to let him out. I believe that this person has a certain prejudice in his heart. In this way, three months is enough time for them to go north and south around Weishui.

"This time, the army marched westward, broke the party in the north, and settled in the south. Countless sergeants were captured. It's just a canal, it's not a problem. Those who only worry about it are repeating the mistakes of the past. ”

Lu Qian gave Sun Zhaoyuan's upper dredging to Huang Qianshan, and Xu Guanzhong also pointed to the map, and explained a lot to him.

And Huang Qianshan paid a hundred attention on his face, but in his heart, he secretly gave Sun Zhaoyuan a thumbs up, which can be a human spirit. Knowing that the military power was too burning for him at such a time, after Dingguan Zhongzhong, and then arranging him, the state Taishou would reach the top, and he had to learn a paragraph first. In this way, it is better to jump out first and do something practical, which will not only satisfy King Lu's appetite, but also give himself more time, so that he can secretly familiarize himself with Lu Qi's rules and regulations.

That Sun Zhaoyuan himself was born in Wenchen, he has been in Guanzhong for many years, successively served as a magistrate, and was promoted as a transfer envoy, and he naturally knows some of the pros and cons of Guanzhong. Now it's a great idea!

When Huang Qianshan came out of the lobby with a Maitreya Buddha on his face, he saw Le He standing under the hall, holding a secret box with a seal on it, and Huang Qianshan recognized this at a glance.

Seeing himself come out, he only nodded and walked into the lobby. Huang Qianshan didn't dare to stay in the hall, so he hurriedly walked out.

I didn't know that in the lobby at this time, Lu Qian checked the seal, took out the key, opened the secret box, and saw the surprised appearance after seeing the report inside.

"Song Gongming took the opportunity of his father-in-law's illness to accept bribes?" Doesn't that make people laugh off their big teeth?

Hei Saburo is an aspiring person, he is an official fan, knowing that what Lu Qian hates most is bribery and bribery, and bending the law for bribes, how dare he know the law and break the law? This is not the timely rain Song Gongming in his impression. ()
