"Many of the generals here have heard of the dangers of Hangu and Tongguan, but if you have a deep understanding, I am afraid that there is no one out of ten."

In March, it was a good season, and Lu Qian had already gathered troops and horses in Jeju.

In this campaign, many famous generals in the Liangshan army had to be brought with them. Lin Chong didn't mention it, and Lu Da didn't need to say much, that Qin Ming, Suo Chao, as well as Hu Yanzhuo in northern Hebei, Zhe Yanzhi of the Zhe family, as well as Yang Keshi, Yang Keshi, Wang Yuan and others, these people who have all kinds of complicated relationships with the Western Army, are effective measures to recruit the Western Army when necessary!

This time, Lu Qian held a military meeting, and they all arrived.

In order to exert the influence of the latter in the Western Army, a prerequisite is to win the Western Army, first of all, to enter the Guanzhong.

And in this entry pass, Tongguan is an unavoidable dangerous place. And to be honest, many people know that Tongguan is dangerous, but where is the danger, I am afraid that there are seven or eight out of ten who can't say it. And among the remaining three or two people, there must be many who can only be roughly said.

How can the few descriptions in the military book show the danger of Tongguan? That also depends on the sand table.

There are many people in the Liangshan army who have a certain understanding of Tongguan, but if you want to say that you know the most, it must be Xu Guanzhong, who personally walked through the Kunhan Road and drew a map of this place. It's just that he gave up this opportunity to Zhu Wu.

"In the early years, Tongguan was located on a loess plateau called Linzhiyuan, and like the dense mulberry plain where Hanguguan was located, Lintoe Plateau was also flat at the top, and extended straight down from the Qinling Mountains to the bank of the Yellow River. The difference is that Hangu Pass is located in the thick mulberry plain, while Tongguan is located on the Lintoe Plateau, which is more than 100 zhang high. Zhu Wu pointed to the north one of the two Guancheng signs on the high ground in the Tongguan area on the sand table. This is the Hantong Pass.

"On the east side of the forest toe plateau is a deep gully called Yuanwang Ditch, and on the west side is a deep gully called Forbidden Gully. Both ditches have water in them, and they have become knife-cut under the repeated erosion of water and rain. When Tongguan was first built, people from the eastern direction of the Guandong wanted to pass through the Lintoe Plateau, they had to climb to the top of the plateau first, then go down to the forbidden ditch on the west side, and then follow the Tongshui to the intersection of Tongshui, Weishui and the Yellow River before entering Guanzhong. Therefore, the Hantong Pass was built on the road that must be passed through the lower plateau. "In the Sui Dynasty, about four miles south of the Hantong Pass, because of the long-term erosion of rain and the water flow in the ditch, there was a ditch at the Yuanwang ditch in the east of the Lintoe Plateau, which reached the forbidden ditch and reached the body of the hill below, and the local people called it "the pit beast threshold valley". In order to control this new passage, the Sui Dynasty built the Xintong Pass on the north side of the upper mouth of the ditch. As a result, Han Tong Pass was called Tongguan North City, and Sui Tong Pass was called Tongguan South City.

"Yuanwanggou does not need to say much, the forbidden ditch is the key, from the confluence of the forbidden ditch and the Tong River in the north, to the Qinling Mountains in the south, about 30 miles long from north to south. The bottom of the forbidden ditch has been washed by long-term rainwater, forming a ramp about ten zhang wide, which has become a military artery leading to the back road of Tongguan City. Because the forbidden ditch can reach the Qinling Mountains to the south and lead to the direction of Wuguan, if the enemy comes from the direction of Wuguan, he will bypass Tongguan and directly enter Guanzhong, so the defense of the forbidden valley is the top priority of Tongguan's defense. As the supporting of Tongguan defense, there are 12 passes built on both sides of the Forbidden Valley Valley, called the Twelve Liancheng, because the Tang Dynasty was forbidden to pedestrians, so it was named "Forbidden Ditch". Zhu Wu pointed to the sand table and said, the twelve checkpoints had already been marked one by one.

"At that time, if you want to climb the body that Tongguan refuses to guard, you must first pass through the first gateway of Tongguan - Jinshu Pass. Even after breaking the Golden Steep Pass, there is a narrow road called Huang Xiangban in front of it. If you want to climb the Lintoe Plateau, you can only pass through the Yellow Lane Ridge. This road is the same as Hangu Road, the south is close to the plateau, there is a high bank uplift between the north and the Yellow River, forming the situation of the plateau in the south and the absolute stream in the north, there is only one hole in the middle, only a few meters wide, only for bicycles, and it is also a pill mud plugged. The locals also call it the "five-mile secret door", "five-mile" describes its length, and the "secret door" describes its steepness. Because the road is dangerous, it can be described as a natural barrier in Tongguan. ”

"Han Sui is far away, and there is no need to mention it for a long time. Let's say that during the Tang Dynasty of the Zhou Dynasty, the water level of the Yellow River was cut down. The Tongguan of Liu Han Yang Sui, because the Yellow River flows close to the plateau, if you want to pass through the Tongguan you can only climb the Lintoe Plateau, but as the Yellow River continues to scour, the river channel continues to deepen, the riverbed will continue to fall, the original riverbed has been exposed when it arrives at Wuzhou, forming a river beach, which leads to the pedestrian coming out of the Yellow Lane, no need to climb the Lintoe Plateau again, you can directly pass the pass from the river beach. For example, the Hantong Pass and Sui Tong Pass on the Lintoe Plateau have become ornaments. Li Tang moved to Tongguan, moved from the plateau to the river beach, the newly built Tangtong Pass is on the south side of the Yellow River valley on a low platform tens of zhang high, about four miles away from the Hantong Pass of Lintoe Plateau in the south. That is to say, from the point of view of the passage value, the Tongguan in the Han and Sui dynasties can no longer be used as a reference, and the current Tongguan is the new Tongguan built in the Li and Tang dynasties. Only stuck in the riverbed of the Yellow River earlier, the passage is much easier than before. However, from the perspective of military value, the two old Tongguan and Twelve Cities are still very important.

While Zhu Wu was saying these words, on the sand table in the hall, a proportional restoration of the Tongguan terrain sand table was placed there. The changes in Tongguan in the past thousand years, and its dangers, have been fully seen by everyone with Zhu Wu's explanation.

Today's Tongguan seems to be more 'passable', and the revelation of the riverbed has made the role of Jinshuguan and Huangxiangban nullified, but even so, it is not easy to break through its checkpoint head-on. As long as the Song army stationed troops on the top of the Lintoe Plateau, arranged some stone cannons and bed crossbows, stationed soldiers and horses in the Hantong Pass and the Sui Tong Pass, and the twelve cities were also mobilized, they did not need much troops, and they could cause great trouble to the Liangshan army.

blindly attacking and fighting, I don't know how many men and horses the Liangshan army will consume, and it may not be able to make contributions.

"The minister thought that instead of storming Tongguan, it was better to focus on Tongzhou. As long as you are willing to pay a certain price and make all preparations, you will definitely be able to break the Song army on the other side in one fell swoop. "Back then, the Qin people attacked the land east of the river from here, so the Liangshan army could also enter the land west of the river here.

Zhu Wu did not agree with the fierce battle of Tongguan, the reason was that it was too dangerous there.

Lu Qian was also embarrassed when he heard it, looking at the people in the tent, there were few people who wanted to fight to the death with Tongguan. You must know that it is Liu Fa who is now sitting in the Guanzhong, and he has no elite soldiers and horses in his hands, and he relies on Xiongguan, and it is not easy to curry favor from him.

It was the first time for Xiao Jiasui to attend such a meeting, and his current identity was a subordinate of the Governor's Office of the Chinese Army, but he no longer served in the military department.

Seeing that everyone seemed to be abandoning Tongguan and rushing straight to Tongzhou, Xiao Jiasui no longer pressed it, got up and said: "The minister thinks that it is not feasible to do things in Tongzhou." It has always been famous, and it has long been known as the Sanqin thoroughfare and the important town of Sanfu, how could the Song army turn a blind eye? Liu Fa of the Western Army, with a serious and steady personality, will inevitably guard here with a heavy army, how can he ignore the same state? ”

Lu Qian's eyes lit up, Xiao Jiasui, a famous 'master of the world' in the original work of Water Margin. Thinking of Xu Guanzhong and Wen Huanzhang, Lu Qian had high hopes for Xiao Jiasui in his heart. Otherwise, he would not have been promoted from the military department to the Governor's Mansion of the Chinese Army, and the post of joining the army would be established in the Governor's Mansion.

"Xiao Jiasui?!"

"It's Wechen." Xiao Jiasui heard a hint of uncertainty in Lu Qian's tone, but he also thought it was normal. After all, he was only a member of the Ministry of War [Langzhong's deputy] earlier, and he was transferred to the Governor's Mansion of the Chinese Army, but he only joined the army as a small child. There is more than one person in a governor's mansion who joins the army. He is only a fourth grade now, and it is already a happy event that his name can be remembered by Lu Qian.

"Huainan Chao Gai once mentioned you more than once in the book, proficient in military affairs, able to make good decisions, Huainan fought you with many meritorious deeds. Today you speak boldly, and this king listens to you. Lu Qian said that he not only remembered his name, but also remembered more.

This identity is different, and the weight of the words spoken is completely different, with Xiao Jiasui's heart, he is already surging with excitement at this moment.

"Thank you for your grace. Weichen only likes to read some military books on weekdays, and he has some shallow views, Huainan fights, and the meritorious soldiers are all soldiers, and the minister only stops moving his lips and does not dare to show his merits. When Xiao Jiasui said this, it can be said that all the generals present were happy, and they all looked up at him.

"Weichen thinks that this Tongguan and Tongzhou are difficult, so why not use the strategy of breaking the east of the river in the past? Our army went out of Linzhou, broke the party and thief left wing, and captured its Yinzhou, and then went all the way south to Yan'an Mansion. ”

Lu Qian's gaze was pinned to the map, and as Xiao Jiasui spoke, his eyes flashed with fine light. He looked at the position of the Divine Warrior Division in the left wing, and looked at Yulin as if it was the future generations. That place can lead all the way to Yan'an. As for Western Xia, he is not afraid of Western Xia at all.

Don't look at the hundreds of thousands of Western Xia troops, in this era, he already has a comprehensive understanding of the military system of Western Xia, and the people of Western Xia are all soldiers.

Among the so-called 500,000 troops, can there be 100,000 people who really have experience in fighting and are fully armoured?

Don't forget that they have just fought a fierce battle with the Western Army of the Northern Song Dynasty, and it is just a respite for two or three years, how can they really recover their strength?

As far as Lu Qian knows, after the Western Xia in the official history was beaten by the Western army, the Western Xia state was already weak, and after the Song and Jin wars, they only took the opportunity to recapture Hengshan, but they wanted to take advantage of the confrontation between Jin and Song to expand the territory, but they failed to do so. It was a situation that was unwilling to be surrounded by the forces of the Jin Dynasty, but was powerless to change the situation of being controlled by others. The Jurchens twice aided the establishment of feudal auxiliaries in the Central Plains, and once returned Henan and Shaanxi to the Song Dynasty, but the Western Xia never received any benefits, and the party members were of course dissatisfied with the Jurchens. However, they have always strictly fulfilled their obligations to the Jin Dynasty. In Lu Qian's view, this is the weakening of the national strength of Western Xia.

For this kind of small country that is only one last kick away from kicking a big hole, will Lu Qian be afraid to start a war with it?

Since the Xixia is a soldier for all the people, it is not bad to kill them ruthlessly, and send the party, a nation that has disappeared in the long river of history in the official history, to where they should go as soon as possible, isn't it?

"Zhao Song didn't get rid of it, he provoked the party first, and he didn't taste too ......" The generals got up one after another and said that it was too strong to do this?

"This king is not afraid of the Liao people, how can he be afraid of the party?" I just didn't think of this idea earlier. "The land on which the party thieves are based is also the territory of my old China. And this king shall be restored. Lu Qian's words were called Zhi Yanzhi, and his eyes lit up when he heard it.

"The generals should not take the party as their intentions, and bluntly say that this plan is feasible?"
