"Okay, good, you're a good junior in high school." The emperor couldn't help but stroke his palms, looking very happy, "I will immediately promote you to the real Xingyuan Yin, no longer need to be any Shaoyin, the title is crowned as the founder of Qi County, the actual seal of five hundred households, the first door to be in front of the halberd, set up a horse, wait until the situation of Xingyuan Mansion stabilizes, and in another year or two, you will not be allowed to enter Taiwan Province as a certain minister." ”

Before Gao Yue thanked him, the emperor added that I would never make a short promise, so I appointed you to be the squire of the military department, the squire of the military department, and then appointed you as the envoy of the Shenwei army of the palace, and together with Wang Xiqian, the supervisor of the army, I will train the troops in Ji County, and immediately the Shenwei army behind the palace will be expanded to 30,000 people, you know military affairs, and you are from a jinshi, I want to use you, and I can trust you.

Gao Yue's brows furrowed slightly:

It's the squire of the military department, and he trains the new forbidden army for the imperial court near the imperial capital, and is responsible for expanding the soldiers and horses - why is the immediacy of this character so strong?

Before he could find this sense of immediacy, the emperor asked him, according to your opinion, what should be the first thing to do in the military in the west in order to be impregnable?

Gao Yue thought about it, then pointed to the emperor with his fingers and said:

In fact, although Ma Chongying escaped this time, my Tang harvest is still very large, originally every time Xifan enters the Kou, he goes to Jingzhou more, why? Because Jingzhou is a plain scattered land, it is conducive to the gallop of the Xifan cavalry. Now it's okay, my Tang has recaptured Pingliang, and built a city in Danzheng Gorge, and the sand castle and the Baicao Army City are also in my hands, and the city is successfully built in turn, which means that the control of the seven passes of Yuanzhou has actually been transferred to my Tang side, and in the future, the Xifan will be separated by Longshan, and it will also be half of the offensive and defensive situation. What I have to do now is to improve the defense line from the northwest to the southwest (forming a strong chain to protect Gyeonggi and Xichuan).

"Good, keep talking."

"The best way is to build a city." Gao Yue then clicked a few times with his finger and said three geographical terms, "Fengzhou Hechi", "Longzhou Huangyuan", and "Yanzhou Wuyuan".

Immediately Gao Yue explained that the Fengzhou River Pond controls the Jialing Water and the Western Han River, which is the confluence of Qindi, Bashu and Ganlong, and this place is under the jurisdiction of my Xingyuan Mansion.

And Longzhou, under the Fengxiang Mansion, is also the avant-garde of Longshan, originally Wei Gao had been in the camp of Huangyang, now can go further, in the state of the original Huangyuan camp city, and then in the small city of Huating camp, with Fengxiang Longright 5,000 soldiers, 3,000 soldiers each guarded, enough to be the front of the iron cavalry of the West Fan over the mountain;

And further north, Yanzhou five originals, there is the benefit of the salt pond, and has always been the Han, Qianghu (party), Xifan forces staggered, desert a horse Pingchuan, especially conducive to the Tibetan riding army, so it is the first place in the West to enter the Kou, if Yanzhou is lost, not only Lingwu lonely hanging, Gyeonggi will also be in danger, Ma Chongying invaded the ranks, took the Yanzhou road, before Yanzhou was weak, the city was not repaired, and there were spies, resulting in the city was broken by Ma Chongying, and Gyeonggi was in a hurry, so in Yanzhou also to build a big city, must be defended by 10,000 strong troopsSince then, it has not been easy to capture Xifan, and the Gyeonggi gateway is naturally safe and sound.

After talking about the three places, Gao Yue used his hand to draw to the end in front of the emperor's eyes, saying that as long as the three cities were built, then taking the Xichuan Shu capital city as the starting point, from the Jinniu Road to the Fengzhou Hechi, and then along the Chencang Road to Fengxiang and Longzhou, and then through Pingliang, along the back road to the sand castle, Baicaoyu, Xiaoguan, you can form a complete and solid defense line, and it is impossible for Xifan to burn and loot our capital in the future.

The emperor asked, "But between Xiaoguan and Lingwu, there is no military city, such as Xifan and then crossing the land of Mingsha to attack, isn't it the same as before?" ”

Gao Yue smiled, said that if Xifan can only cross the Yellow River and invade Mingsha after that, it is equivalent to being helpless, if he dares to cross Mingsha, he will inevitably be blocked under the Jiancheng Yanzhou, and then my Yuanzhou and Lingwu troops will be surrounded from the north and south, and the Yanzhou city soldiers will fight hard, Xifan will be attacked on three sides, and there will be the Yellow River behind, it is easy to advance and not easy to retreat, and the tragedy of Ma Chongying will be repeated. As for why not build a city in Mingsha or Zhongwei, and directly block Xifan to the west of the Yellow River, mainly because this area is mostly desert sandy land, and it is not easy to replenish it, so it is necessary to wait until Yuanzhou and Lingwu waterways are connected and unblocked, and then it is not too late to set up a new military city here.

"The waterway between Wonju and Yeongmo?" The Emperor was a little puzzled.

Gao Yue said that this was a plan that had been successfully used by the Northern Wei Dynasty in the past, and the minister got it from the book, and wanted to pick up the wisdom of the ancients.

"You can say it carefully."

Gao Yue said that in the previous period of time, the ministers led the army from Lianyunbao in Jingzhou, to Pingliang, to Xiaoguan Baicaoyu, and then to Anle Prefecture, until the old city of Mingsha by the river, so not only from the book, but also from the actual experience:

Lingwu is a good place, and its barren Yanzhou, Gyeongju, Yuanzhou are different, it is adjacent to the Yellow River bank gentle, the fields are flat, and there are many ditches for irrigation, very fertile, if you can restore the camp, the annual income of 600,000 stone is not a problem, not only can support the needs of the town, but also support the Jingyuan in the west, plus immediately in Fengxiang, Jingyuan, Xingyuan, Suining and other places of the camp, within two or three years, the imperial court will not have to travel thousands of miles from the southeast of the Jianghuai to transport grain.

However, there is a problem, that is, the land route from Lingwu to Jingyuan is a dry sea desert, the sand is soft, if it is transported by heavy trucks, it will inevitably sink, but if it is transported by light vehicles, manpower and animal power will inevitably cause a huge waste - in short, if 600,000 stones, it would be good to have 100,000 stones sent to Jingyuan.

Now we can open the road of water transportation, destroy the sand castle and the Liupan Mountain mountains guarded by the Baicao Military City, there are many timber production, so that the soldiers stationed in Tun can cut down, build 200 boats, and then go to the Hulu River and Weiru River into the Yellow River, and then transport grain along the Yellow River to Lingwu City, and return to the land of Jingyuan to hoard and fund the needs of military and horse herding. 600,000 stones, 500,000 stones can be successfully delivered, which can save a lot of money every year.

As long as this route is passed, our Tang will have a surplus, in the mouth of the Weiru River and the Yellow River to build a city and guard, at that time, the entire defense line against Xifan is completely complete, I Tang can rely on the border army to hold the pass and the river, but there is no need to draw the autumn soldiers from the eastern part of the country, the annual savings of 2 million yuan, 2 million stone of grain, with this money for Your Majesty to replenish the training of the Shence, Shenwei army, can cooperate with the border army to directly attack Longyou, recover the lost territory.

"Is the river navigable?" The Emperor asked.

Gao Yue gave an affirmative answer, saying that to build 200 ships, each ship can carry a thousand Hu (stones), with two ships as a program, one program of ten soldiers with bows and crossbows, ten husbands rocking the oar, the total need for thousands of soldiers, 1,000 boatmen, each time can carry 200,000 stones, from Yuanzhou and Lingwu for a total of 60 days, the Yellow River can be navigable from March to September, three trips can achieve the goal of 600,000 stones, not only to transport grain, but also to transport troops.

The emperor clapped his hands and said that listening to the words of the senior high school made me have the intention of sealing the wolf!
