Duke Zhuang paused a little and then introduced that Zhongguan in the three Guanzhong was Wuyang Pass, which was called Wuyang Pass in the Southern Qi Dynasty, which was called Lishan Pass in the Tang Dynasty, and later Wuyang Pass. It is seventy miles south of Xinyang, at the junction of Henan and Hubei, and is an important pass between Dabie Mountain and Tongbai Mountain. It is the south of Ezhou and the north-south Central Plains, which controls the throat of north-south traffic.

Wuyang Pass is located in a dangerous place, with mountains intertwined nearby and peaks surrounded by peaks. The city of Guancheng is blocked by mountains and made a pass. In ancient times, "cars cannot be squared and horses cannot be ridden together" describes its danger. It has always been a place for north-south to compete with the north and south, and it is a must-do way to conduct a military command. It was traced back to the battle between Huangdi and Chiyou. After the Spring and Autumn Period, there were more than 60 large and small wars recorded in all sizes. Sun Wu once led his army to attack Wuyang Pass in one fell swoop, and then occupied Yingdu, resulting in "Chu lost three passes and then lost its country."

During the Southern and Northern Dynasties, Liang and Wei fought over the three passes for decades in order to gain control of the passes. In the first year of Kaiqing in the Song Dynasty, Kublai Khan led his army to cross the Huai River and attack Dasheng Pass. The Song army was defending the pass and could not defeat it. Later, because the garrison troops abandoned the pass and fled south, they went south to take Ezhou, forcing Song to seek peace and form the "Ezhou Alliance". Yue Fei also used this place as a base for regaining the Central Plains and sent the general Niu Gao to guard Xing'an Village on the west side of Wuyang Pass.

The east gate of the three gates of Yiyang is Jiuyang Pass. It was called Dasui Pass in the Spring and Autumn Period, and later it was also called Huangxian Pass, Guangxi Pass, and Baiyan Pass. In the early Han Dynasty, the county was established here. Because the gate was nine miles north of the county town, the Song Dynasty changed it to Jiuli Pass. The mountains on the east and west sides were steep and winding in the wind, the two mountains stood in a cliff, and the water flowed in the water, occupies the dangerous mountains, which was the most concise, and it was a place of war fighting in history. The narrowest part in the middle was the site of Jiuli Pass. In ancient times, it was described as "the chariots did not have square tracks, and the horses did not ride together", which shows that the land was rugged and dangerous, and the roads were difficult to move.

This pass is adjacent to Luoshan, with two mountains standing in the sky, and the Tiancheng Canyon, ten miles north and south. The terrain is dangerous, with narrow ends and wide in the middle. It is connected to Dongzhai, Shugang in the north, Dabieshan Mountains in the east, and Dawu Mountains in the south, and Sanli City is connected near. Jun has been a post road inn in the past dynasties, with merchants gathering from south to north, and iron cavalry, and the street market is prosperous. It is an important way to exchange characters between the Central Plains and Jianghan.

"At present, our army has seized the three passes and controlled the Tongbai Mountains and the prefectures south of the prefectures, but the Yuan army still controlled some prefectures and counties north of the mountain, especially in Shangshi outside the Pingjing Pass," said Zhuang Gong.

"As you said, can't we pass through Pingjing Pass and pass through the mountainous areas and enter the Jinghu area?" Ni Liangfa asked.

"That is, although our army is not afraid of enemy soldiers, we are in the army and have a large army of vehicles and fighting, so it is inconvenient to advance and retreat, so it is easy to defend but not to attack. If we are entangled with the enemy, we can stand in an invincible place, which will delay our journey. Therefore, I think it is not appropriate to go to Pingjing Pass." Duke Zhuang said in his words.

"Well, this statement is reasonable." Ni Liang nodded and said, "But if your preface is true, the roads at Jiuli Pass are narrow, and the carriages cannot be square, and horses cannot ride together. Our military chariots must be impossible to pass, so we can only go to Wuyang Pass."

"What General Ni said is exactly, he can only go to Wuyang Pass when he walks." Duke Zhuang nodded.

"I think it's inappropriate!" Tan Fei interrupted at this time.

"What are the objections of Commander Tan? Do we want to abandon the car and go to Jiuyang Pass? This will cause many inconveniences and will delay your future trip." Duke Zhuang asked back frowned.

"Please see everyone!" Tan Fei did not make any excuses, but stood up and walked to the front of the map and said, "Please see, the three passes of Yiyang are formed with horns, Jiuyang Pass and Pingjing Pass are like horns protruding from the front. Wuyang Pass is like Newton in the back, and Cheng Pass is placed in the narrowest part of the valley. If you pass, you must march in the valley for 30 miles."

"We are now marching in a brigade. The brigades are winding for several miles, and they must be detected by enemy spies. Even if they do not know how to drive in it, such a large-scale brigade must be considered a brigade. It only requires a few hundred elite troops to lie on both sides of the valley, block the road when the brigades pass by and set fire to the fire. The road is narrow, and the vehicles are in trouble, and there is nowhere to avoid it. The brigades are loaded with firearms and flammable objects, which are difficult to extinguish when burned, and the consequences are unimaginable." Tan Fei said.

"We can send alerts in advance, block the valley entrance, and set up observation posts on both sides of the valley to cover the army to pass!" Duke Zhuang retorted.

"We can also use the method of crossing the valley in batches." Tian Zhong, the chief commander of the First Brigade of the Guard, took the speech, "When crossing the valley, the brigade is divided into several teams, and the two teams move forward in a few steps. Once attacks are encountered in the front or rear, it can not only be avoided from being trapped in the entire army, but also rescue each other. When they are mixed in, how can the enemy make a clear attack?"

"Your Majesty is a body of gold. You cannot take risks with yourself. If you have any chance of being in danger, we should avoid it. You cannot let Your Majesty suffer any damage." Ni Liang said muffled after hearing this.

"So how to do it? Do we have to fight against the enemy, attack the enemy dozens of miles away, and then walk to Pingjing Pass, then Your Majesty's actions will also be exposed." Duke Zhuang said excitedly.

"Divid the troops." Tan Fei said, "We divided our troops into two groups. The brigade still walked in Wuyang Pass in a chariot, while the other team was light cavalry and walked from Jiuli Pass, and then met in Yingshan County."

"You mean to drive to Jiuyang Pass. Although it is under the control of our army, there are still enemy rangers outside the pass. Once you encounter an enemy, you will inevitably fight and even attract a large number of enemy troops to pursue you. If the escorts are insufficient, your Majesty will still be in danger." Tian Zhong waved his hands repeatedly.

"If the troops are divided into two groups and escorted by a large army, they can only pass the pass on foot. Once the chariot is attacked, they can revolve in an open place to protect themselves. However, if they are attacked in the valley, they cannot send troops to retreat, and they will inevitably be burned to death." Duke Zhuang also disagreed.

"What do you think?" Seeing that everyone was arguing endlessly and it was difficult to make a decision, Ni Liang looked at the little emperor who had been listening quietly and said.

"There is no complete solution in the world. We sank day and night and stop the ball. How can they know that I am in the army? Even if they find out that I am in the army, I don't know where to pass the test now, so how can they know!" Zhao Bing spread his hands and smiled.

"..." Everyone was shocked when they heard this, but they knew the point of what Your Majesty said. They didn't know how to pass the pass, and how the enemy made a judgment. Even if the enemy immediately learned the news after their decision, how could they quickly send the news back and mobilize soldiers to set up an ambush or round up. However, everyone also understood that the key to protecting Your Majesty's safety was not which way to go, but quickly pass the pass before the enemy responded...

...

Two days later, the city gate had already been closed. The soldiers of Xicheng suddenly discovered that smoke and dust were rising outside the city. They knew that it was a sign that the gang of cavalry came. However, the team did not show their flags and could not tell whether they were enemies or friends for a while, so they immediately sounded the alarm bell. For a moment, police numbers in the city rose everywhere, and lanterns and torches on the city were lit, illuminating the city, illuminating the city, and the dozens of cannons had been loaded, aiming at the direction of the cavalry.

Not long after, more than 400 cavalry had arrived at the city and lined up outside the range of artillery fire. But they were wearing the uniforms of the Song Dynasty imperial guards, but they still did not show their flag. The war horses were much taller than other cavalry. Although they were covered in dust, they were also in a strict line and were not messy at all. However, the sabers were sheathed, and the muskets were also horizontal, above the saddle, indicating that they were not hostile.

"I am the garrison of the Fourth Army of the Great Song Dynasty Imperial Army stationed in Yingshan County, and I am here to report the military number!" Wu Feng, the commander of the Third Division of the Fourth Army of the garrison of Yingshan County, saw the situation and asked loudly.

"We are the first battalion of the Cavalry Regiment directly under the Huaibei Marching General Office. We come to your official corps. Please open the city gate!" A cavalry in the queue under the city went forward to the city and replied upwards through the moat.

"Oh, it is a friendly army of the General Administration, but I am responsible. The city gate is closed and I dare not let it go without authorization. Please show the pass certificate and the sign of the waist!" The Fourth Army of the Imperial Army was under the jurisdiction of the Jiangdong General Administration Office in the past, and the Huaibei General Administration Office was changed after the Northern Expedition of the Jiangdong General Administration Office. There were people who were familiar with it, but it was dark and it was difficult to see the person clearly. He replied.

"I'd like to ask the general to lower the suspension bridge and let the lower officials enter the city and present the documents and ask the general to check." The person below dismounted and said.

Although the other party came to see each other alone, Wu Feng still did not dare to ignore it. He ordered the soldiers on the city to be on guard against the enemy's makeup and pretended to be the opportunity to put down the suspension bridge and open the city to launch a surprise attack. Then he ordered the suspension bridge to be lowered, and immediately put the suspension bridge after he crossed the bridge, halfway open the city gate and let him enter the city. He confiscated the weapons he wore before he could meet him in the city.

"Sir, please see the Dutong of Wu!" The visitor saluted and said.

"Tan Fei, you are not..." After seeing the face of the visitor, Wu Feng stopped in the air, and said in surprise as if he was seeing a ghost. He and Tan Fei were both from the General's Mansion's personal guard camp, so he was naturally familiar with him. He also knew that he had taken over Chen Dun to the imperial guard camp. As the leader of His Majesty's personal guard, he should always be with the emperor, but suddenly appearing in this small Yingshan County, how could he calm down? It can be seen that he shook his head gently, realizing that he must be carrying out a secret mission, otherwise he would not be able to perform it, so he swallowed his questions and waved his hand to let the guards retreat.

"I'll tell you the details later. Your Majesty is outside the city. Open the city gate quickly to welcome Your Majesty into the city. Remember not to make a statement." Seeing everyone retreating, Tan Fei stepped forward and held his ears.

"Ah..." This news surprised Wu Feng even more than seeing Tan Fei suddenly. He quickly covered his mouth and turned his face to look down at the city, but in the darkness, there could be anything that could be distinguished from the tight queue.

"Your Majesty will have the opportunity to meet you after entering the city. Please order the city to open!" Tan Fei said with a hint of amusement when he saw his panic.

"I have already experienced a clear document, open the city gate quickly and welcome... to line up to welcome friendly troops into the city!" Wu Feng was transferred from the front guard to the Fourth Army of the Imperial Army when he was recapturing Jiangnan and expanded his army. He had not seen His Majesty for several years. He still couldn't help himself. After calming down for a moment, he turned around and ordered...
