Wuguan is one of the four passes in Guanzhong.

The four passes in Guanzhong are also the four stops of Qin, which are Wuguan, Xiaoguan, Hangu Pass, and Dasan Pass.

These four passes are the gateway of Guanzhong, of which Hangu Pass is the east gate, so that Guanzhong can communicate with the land of Luoyang in the Central Plains, at the end of the Eastern Han Dynasty, Cao Cao established Tongguan, and since then Tongguan has replaced the status of Hangu Pass.

And Xiao Pass is located in Longshan, that is, not long ago, where Liu Chan fought against the Wei army.

Xiaoguan is the north gate of Guanzhong, mainly to guard against the Hu people in the north, because the north of Xiaoguan is not far away, which is Helan Mountain, which has always been the settlement of the Hu people.

Dasanguan is the south gate of Guanzhong, located in the south of Chencang, in history Han Xinming repaired the plank road to darken Chencang, and walked through Dasanguan, Zhuge Liang's Northern Expedition to attack Chencang, also passed through here.

And Wuguan, located in the southeast of Guanzhong in the Qinling Mountains, and Nanyang communication, in the Spring and Autumn Period and the Warring States Period, Wuguan is the place of inspection of Qin and Chu, and it is also one of the most important gateways in Guanzhong.

If there is no Wuguan, from Guanzhong to Nanyang in Jingzhou, you have to go east to Sili first, and then go south from Luoyang, making a detour for thousands of miles, which is very troublesome.

Wuguan is located in the remaining veins of the eastern foot of the Qinling Mountains, its mountains and rivers surround, dangerous and natural, once known as "the heavy pass of the Tiansai control of the Shenzhou", "the door is not locked the enemy is difficult to commit", "Wuguan is closed in Qinzhong, Xiangyun Jianghuai Road is not passable".

Wuguan is built on a flat plateau, its north leans on Shaoxi Mountain, it is a cliff, the south is bordered by a stream, the river is surrounded by east, west and south, and the city site crosses the center of the river.

Its city opens the door from east to west, there are four ridges in the east of the city, especially the suspension bridge ridge is high and steep, go up the mountain together, do not allow to ride together.

Guan Yu set out from Jingyang, led the cavalry to march lightly, and as Liu Chan expected, arrived near Wuguan on the afternoon of the fourth day.

In fact, this distance, if it is all plains, it will not take four days, mainly because Wuguan is located in the remaining veins of the Qinling Mountains, and Guan Yu walked a section of the mountain road, which only took four days.

Guan Yu arrived twenty miles away from Wuguan and ordered the cavalry to rest.

Guan Yu, Pang De, and Huang Xu sat together, Huang Xu looked at the map for a while, and said to Guan Yu: "General, this place is only twenty miles away from Wuguan, and you can reach Wuguan before sunset." ”

Guan Yu nodded, and ordered Huang Xu: "Let the soldiers change into the armor of the Wei army, and take the Wuguan before sunset." ”

Pang De frowned and said: "General, although Fa Situ's strategy is good, but when you transfer troops and send generals, you always need to show a letter of order and the like, what if the Wei army wants us to show a letter of order?"

Grain and grass can only let us stay here for two days, there is only one chance to seize Wuguan, if a blow fails, the Wei army has a defense, with the steepness of Wuguan, our five thousand cavalry can not attack.

In my opinion, let's not rush to act today, let's go and see the terrain of Wuguan first. ”

After listening to Pang De's suggestion, Guan Yu nodded and said: "This is not bad, I can't figure it out Ling Xin, but it's good to go and see the terrain of Wuguan first." Let's ride over and have a look. ”

"No!"

Guan Yu and the three of them immediately got on their horses and headed in the direction of Wuguan.

The three of them came to a hill in front of Wuguan and looked at Wuguan from afar.

Wuguan opened the door from east to west, Guan Yu came from the west, and it was the west gate of Wuguan that needed to be attacked.

Wuguan north leans on Shaoxi Mountain, south is on the verge of the stream, the city site crosses out of the river center, only to see outside the west gate of Wuguan, is a river about three zhang wide, the rapids are turbulent, this river is called Danshui, is one of the branches of Han water.

Outside the west gate of Wuguan is Danshui, if you want to enter Wuguan, you need to cross a suspension bridge, if the Wuguan defenders do not put down the suspension bridge, the soldiers and horses will not be able to cross the river.

If the river is forcibly crossed, the turbulent water is inconvenient to move, not to mention, the soldiers at the head of Wuguan City can also attack with arrows.

Looking at this Wuguan, Huang Xu said: "Wuguan is really worthy of being one of the four Qin Sei, and Emperor Taizu Gao was the one who entered from Wuguan to destroy Qiang Qin.

The Danshui is turbulent, as soon as people enter the water, there is a danger of being washed away, the drawbridge is controlled by the Wuguan defenders, and if you want to take Wuguan, you can't attack it at all, and you have to coax them to open the door by themselves. It's just that although we have the armor of the Wei army, we don't have a letter, how can this be good? ”

Pang De smiled bitterly: "We don't know who the Wuguan guards are, so we don't dare to bet." If the general is incompetent, it is naturally good not to ask for the letter, but if he asks for the letter and we can't get it, then the operation will be considered a failure. ”

"I have a plan, even if I don't have a letter, I can take the martial arts!" Guan Yu stroked his beard and said.

Pound, Huang Xu hurriedly asked, "What is the general's plan?" ”

"Let's go back and listen to my arrangement first." Guan Yu smiled, then turned on his horse and returned to the camp.

The sun is setting, and the remnant sun is like blood.

The two cavalrymen, covered in blood and with an anxious face, went straight to Wuguan.

The two of them walked to the drawbridge and shouted at the defenders at the head of Wuguan City: "Quickly put down the drawbridge!" ”

"Stop, who are you?" Seeing this, the defenders on the Wuguan hurriedly put on guard, and the soldiers bent their bows and arrows, ready to shoot at any time.

"Where is the guard? Get him out! ”

"The military situation is urgent, let the guards come out!"

"If you delay the big event, you can't eat and walk around!"

The two soldiers looked like Lao Tzu was the best in the world, not only did not explain their identities, but kept urging the defenders to call the guards over.

Seeing that the two soldiers under the pass were wearing their own armor and talking with a bullish look, the defenders did not dare to be careless, and hurriedly called the guards.

"I am Xiahou Sheng, the general of the martial arts, who are you?"

This Wuguan guard is a member of the Xiahou clan, but he is not a direct descendant of Xiahou Yuan and Xiahou Yuan.

A soldier shouted: "A few days ago, the general was defeated in Longshan, Longshan has been captured by the Shu army, and now the general has withdrawn to Chang'an, Your Majesty is worried that the Shu army will seize Wuguan first, and specially sent General Cao Chun to lead the army to garrison."

It's just that he encountered the cavalry of the Shu army on the road, and now he is fighting not far ahead. Most of our troops are foot soldiers, and they are defeated by the Shu army, so General Cao ordered me to come over and let you go out of the pass as soon as possible. ”

Cao Chun has been dead for a while, but Wuguan is located in the remote area of the southeast, and he doesn't know the news, don't say that it is Wuguan here, even Chencang, Huating and other frontlines, and they don't necessarily know.

Xiahou Sheng asked, "Is there a letter from Your Majesty asking you to come over to guard Wuguan?" ”

"The military situation is urgent, General Cao has no time to deliver the order letter, you come out quickly to respond, if you delay the big event, you will have good fruit to eat." The soldier scolded angrily, ignored Xiahou Sheng, and rode his horse forward again.

"What about the general? Shall we go and answer? The deputy general looked at Xiahou Sheng with an embarrassed expression and asked.

Xiahou Sheng said: "I haven't seen Ling Xin, I can't just open the door and go out, you quickly send someone out to investigate the situation and see if what they said is true!" ”
