Guanzhong. It is located between the two major mountain systems in the north and south, and is formed by the Weihe River and its tributaries. South of the Plains. There are more than 400 kilometers of Qinling Mountains as a barrier. From the west, west, and east, there are towering and ravines of Taibai Mountain, Shouyang Mountain, Zhongnan Mountain, South Wutai, Cuihua Mountain, Lishan Mountain and the tall and steep Huashan. east to the west of Henan Mountain; The North of the Plains. There are the remaining veins of Liupan Mountain. To the east, there are Qianshan, Qishan, Qiaoshan, Liangshan, Jiushan, Sushan, Sagashan, Yaoshan, and Huanglongshan to form the continuous Beishan mountain system.

In the west of the plains. Longshan is connected with the Qinling Mountains from northwest to southeast. Blocking the western edge of Guanzhong leaves only one passage for Weishui. And on the eastern edge of the Guanzhong Plain. The Yellow River roaring in the Jinling Mountains. Straight down from the north. After Hancheng rushed out of Longmen Mountain. The river is wide and becomes a natural boundary ditch at the eastern end of the plain. As can be seen from the above. The topography of the four holy ring mountains in the Guanzhong Plain. It constitutes a natural defense line as the location of the capitals of Qin, Han and Tang.

Blocking mountains and rivers. The land is fertile. It's all about tyrants. Higashihanya. Nanbu Seki. Xisanguan. Beixiaoguan. Four-key lock. Rock solid. Historically. If it is not for the civil strife in Guanzhong or the internal ruler is rotten. so that there are many complaints. The morale of the army is disheartened. External force alone is not the work of a few years. Extremely difficult to break.

However, since the end of the Tang Dynasty. The land of Guanzhong is divided into two. Half of it was under the rule of the Tubo people of Longyou. Guanzhong's territory has shrunk. This North Xiao Pass envoy does not belong to the Guanzhong. So when Hu Xier lobbied Zhao Guangmei. Abandon this Beixiao Pass. Replace it with Fenyang's Golden Radium Pass. But Guanzhong is surrounded by mountains. There are certainly dangers in the passage of communication with the outside world. Like Longguan, Yaoguan, Wuliguan, Linjin Pass, Muhu Pass, Golden Lock Pass, Shimen Pass and so on. It can be said that there are many passes. But it is on the outward avenue of Guanzhong. It has the meaning of "lock key" and plays a controlling role. It's really a "one-man affair. There are only four portals that are easy to defend and difficult to attack. Then Hangu Pass, Wu Pass. Dasanguan and Xiaoguan.

Xiaoguan was occupied by the Tibetans for many years. Now it has fallen into the hands of Yang Hao. Then the north gate of the closed is actually open. And the Tibetans fought year after year. The wolf smoke never stops. It has long been familiar to the defenders of Guanzhong. Yang Hao defeated Shang Boqian with lightning speed. Because it's too fast. The Song army in Guanzhong still didn't know anything about it. I didn't know that the Western Xia army was already aggressive. Swing south.

Until Tong Yu, Tie Niu and Ke Feed's evil army slaughtered to Longshan. Longshan is extremely dangerous. Accordingly, go east. Controllable chokehold. Accordingly look south. Can win Hanzhong, Bashu. Longshan is the remaining vein of Liupan Mountain. Stretches for hundreds of miles. It is the right auxiliary of Chang'an. In the south of it, there are Baoji, Dasanguan and other passes. The throat of Guanzhong, Hanzhong, and Bashu should be rushed; In front of its mountain, there is Longguan. Control the main road leading to Longyou in Guanzhong.

Yang Hao's order to Xiaoliu, Ke Zhiwei and others was: to seize Guanzhong as quickly as possible; Minimize losses as much as possible. Multi-wise. Less force. He who can be used to make peace of mind. and will not use force. Because Princess Yongqing played the role of "Zhao Defang, King of Qi" to participate in it. Doomed to the Battle of Song. It's both hitting and pulling. It's not an absolute conquest. Excessive kill pokes. On the contrary, it will arouse the hatred of the Song army. Do not take advantage of the execution of the plan.

As for the specific measures. None at all. Fighters are changing rapidly. It's not something that Yang Hao can master. So he has been given full command of the three former enemies. This has to do with Zhao Guangyi. Hating not being able to directly command the specific actions of a team and a team is completely different. Zhao Guangyi commanded the First Battle of Liao. That's how it works. It's just that there were no telephones and telegraphs in those days. He is possessed by Guanyin with a thousand hands and a thousand eyes. Nor can he command a first-level general of the 300,000 army. At most, it is specific to the army and battalion level. It is precisely because the authority is too heavy. So when the Liao army raided into Youjing. The surrounding Song troops did not dare to move. I can only defend my own position. Watching the enemy army enter the city. And that's exactly what it is. Zhao Guangyi fled on the donkey cart. The armies of all walks of life were immediately leaderless. There is no way to retreat. From being invincible to being defeated.

Yang Hao attaches great importance to military power in army building. In the construction and training of the army, some of the advantages of the Quanjun army were borrowed. But the specific command of the expedition operation. But absolutely decentralized. Give full autonomy to the command staff of the former enemy.

When Tong Yu led the army all the way south. happened to meet Barcelona escorting Shang Bo Qianbei back. Suddenly I had a plan. So he ordered someone to report to Yang Hao. With his consent. Bring Shang Boqian with you. Rushed directly to Longguan.

The Longguan guard will be Zhang Tai. Shang Bo Qian Zongheng Longright. It was supported by the Song court. Tong Yu has been under Shang Boqian for so long. Nature knows about it. In fact, most of the Tibetan generals knew about it. With this strong reinforcement. It is Shang Boqian's prophecy. How could he not have a reason not to say it? As a general of the garrison. Of course, Zhang Tai also knows these inside facts. Tong Yu even knew that Shang Boqian had invited Commander Zhang to eat. Played with women. He was also given a precious mink robe. At this time, Shang Boqian is just used as a stepping stone. In order to achieve Yang Hao with minimal losses. Orders for maximum benefit.

Battle of Longguan. There was no suspense. This Xiongguan. Because there is no strong enemy on all sides. 天長rì久. The defenders have long since slackened. Then I saw the army of Tong Yu dressed as a Tubo soldier who came in a hurry. Seeing Shang Boqian, who was half-dead and still had a breath left. Commander Zhang had no doubts. Immediately switch them in.

The Longguan Fortress easily fell into the hands of Tong Yu. Tong Yu left a small number of troops to guard the disarmed Song army. Keep running forward. Bypass Baoji. Straight to the big dispersion.

He knows. Behind his back. Soldiers and horses from all walks of life will continue to come. His next goal is the Great Sanguan. Once the big scatter is in hand. Baoji City between Longguan and Dasanguan. It's just a lonely boat in the sea. It can be overturned at any time.

When it comes to defense, no one is better at it than him. The fastest/more / station / address

Since jīng is through all kinds of means of defense. Naturally, he also knows the weaknesses of the city's defenses. And the Great Sanguan! It is an important pass in Guanzhong. But the means of guarding the pass are much inferior to him. Tong Yu handed over the command of the Lord to Ke Zhenxi. He is solely responsible for conquering the Great Scattered Pass. Ke 嬉 evil shake jīng god. Just under the Great Enemy Pass, he unleashed his skills.

The Song army was in disarray. Defeated. Zhao Guangyi was shot. was first robbed by the inner guards and fled. Then the Song army dispersed in a hurry. Fight for each other. Fight and retreat. There is only one direction: south.
