"That's great. I'll take the transshipment envoy nearby!" Ma Zhou immediately said excitedly when he heard Han Qi's words. Since he arrived at Gubeikou, he has been worried, mainly because the Great Wall in Gubeikou is so dilapidated and his troops are very limited. If an enemy really attacks, he will not be able to defend Gubeikou at all. At most, he can only send a warning signal to Xijin Prefecture.

Gubeikou is the Great Wall between Shanhaiguan and Juyongguan. It is divided into four sections, namely Wohu Mountain, Panlong Mountain, Jinshanling and Simatai. Most of these four sections are built on the mountain ridges, and there are very few roads that can be used. There is a passage between Wohu Mountain and Panlong Mountain. The Great Wall sets up a city at this pass, guarding this passage tightly. This is also the place where Ma Zhou and others mainly stationed.

"Please look at the transferor. This urn city is located on the Great Wall passage. There are Great Walls on both sides of the mountains. If the army wants to cross the Great Wall, it must pass here. The terrain here is easy to defend and difficult to attack. If the enemy attacks for a strong force, it will inevitably suffer several times of casualties!" Ma Zhou took Han Qi to the urn city at the gate and introduced him.

Han Qi was also looking at the urn city built by the Northern Qi Dynasty. It was a pure military fortress. There were no people living in the city. The entire city was not big, but it was like a big jar. The gates were blocked tightly. Even if the enemy entered the city, the defenders at the top of the city could seal the enemy in the city and eliminate them calmly. It could definitely be called a one man as a pass, and ten thousand men would not open.

Han Qi followed Ma Zhou into the city, then climbed the city wall and looked around. However, when he saw the Great Wall on both sides, Han Qi couldn't help but sigh inwardly. He saw that the Great Wall on both sides had already been dilapidated, and some of the city walls collapsed and could not play a defensive role.

Even the urn city under Han Qi and his team looked good outside, but when they climbed to the top of the city, they found that many places in the entire urn city were very dilapidated. As far as Han Qi knew, there was originally a Liao army stationed here, but the Liao Kingdom did not attach importance to it. The Liao army stationed here mainly collected taxes. After hearing that Xijin Prefecture was captured by the Song army, the guards here immediately led people to escape, leaving Ma Zhou and others an empty city with nothing.

"This Great Wall was almost always built by the Northern Qi people in order to prevent the Xi people from abroad, so it is also called Xiguan. The Northern Qi was not very strong at that time. The construction of the Great Wall was mainly made of bricks and earth, and it was not very strong. Later, during the Sui and Tang Dynasties, the Great Wall was not paid much attention to it, so it has not been well repaired. Not to mention it after it was occupied by the Liao Kingdom. So over the years, this Great Wall has collapsed many places. If it is not renovated, it may be of great use." Ma Zhou said again and introduced.

"Apart from the Xiguan under our feet, are there any other passages on the Great Wall?" Han Qi finally asked.

"Yes, please look over there!" Ma Zhou took Han Qi to the other side of the city wall at this time, and then pointed his hand.

Han Qi also looked in the direction Ma Zhou pointed out, but found that the other party was pointing to a dense forest, which made him stunned, but then he found something was wrong because he heard the sound of water flowing, and it was quite turbulent, which made him immediately speak, "Is there a river?"

The city walls of Xiguan are not very high, and it is summer and the trees are very lush, so the trees on the river bank block the river surface. The river surface cannot be seen at Han Qi's station, but because the river is not far away, the sound of water flowing can be clearly heard on the top of the city.

"Yes, there is the Chaohe River that crosses Xijin Prefecture. This river passes through Gubeikou from the Liao Kingdom and then flows through the city of Xijin Prefecture. Because the Chaohe River flows rapidly and the sound of water is like a tide, it is also this river that cuts the Great Wall into two sections. If the Liao people go south, even if we guard Xijin Prefecture, the other party can go downstream and go directly under the city wall of Xijin Prefecture!" Ma Zhou said helplessly at the moment. Xiguan did have to guard the land route, but the water route is not within the defense range of Xiguan.

Han Qi frowned when he heard this. Of course, he knew that almost all the water intake in Xijin Mansion was relying on this river. However, he did not expect that the Chaohe River actually flowed from the Gubei mouth. With this river, there was also a huge gap in the Great Wall defense line. Even if the Liao people are not good at water battles, it is a big hidden danger after all.

"General, if you want to rebuild the Great Wall in the future, I will feel that you can expand the scope of this Xi Pass and then include Chaohe River in the city. In this way, Xi Pass can cross the Chaohe River and set up a sluice on the river. If the enemy comes to land, no ship will enter or exit after the sluice falls!" At this time, Ma Zhou hesitated for a moment, and finally spoke and suggested.

Han Qi did not answer immediately when he heard Ma Zhou's suggestion, but pondered for a moment before taking a walk: "Let's go, take me to the Chaohe River for a walk!"

Ma Zhou immediately agreed when he heard this. Then the two of them got down the city wall together and walked towards the Chaohe River. Xiguan was originally on the Chaohe River, and the distance between the two places was only about a mile away. Therefore, the two walked directly to the river and saw that the trees here were extremely lush and mostly tall tung trees. Just to facilitate water collection, a small path was built from Xiguan to the river.

"In the past, the Liao army was stationed in Xiguan and charged heavy taxes to merchants who came and went to and evade taxes. In order to evade taxes, many merchants took risks and loaded the goods on the ship and crossed the Great Wall from the Chaohe River. In order to prevent the soldiers at the Xiguan city from discovering, they also specially planted a large number of tung trees on the river bank. The maple trees grew fast and the trees were tall, just blocking the vision at the Xiguan city, so that they could not be afraid of being discovered by the Liao army during the day." Ma Zhou introduced to Han Qi while walking.

Han Qi was also amazed when he heard this. He thought it was normal for the trees by the river to be lush, but he did not expect that it was planted by those smuggling merchants. This is a strange story. However, now that Xi Guan has fallen into the hands of the Song Dynasty, these trees will definitely be cut down in the future.

In a short while, Han Qi and Ma Zhou came to the riverside, and Han Qi estimated the distance. It was indeed very close to Xi Pass. It could completely expand the area of ​​Xi Pass and include the entire Chao River. After all, there is a cliff on the other side of Chao River, which is also very suitable for building a city.

"This section of Chaohe River is relatively narrow. After all, there are mountains on both sides, which makes the river water very turbulent when it flows through here, and there are many huge rocks and reefs under the river. In the past, smuggling merchants often caused ships to be destroyed and killed. Therefore, except for some old river workers who are experienced and familiar with the local water conditions, ordinary people dare not sail from here." Ma Zhou introduced again immediately.

"It's not bad, General Ma's suggestion is very pertinent. If Xiguan can be extended here, the defensiveness of Gubeikou will be greatly enhanced!" After inspecting the terrain on the spot, Han Qi finally nodded and praised.

Seeing that Han Qi agreed with his suggestion, Ma Zhou was very happy and humble, but at this time, Han Qi suddenly found a corner of eaves on the hillside near the river bank, which made him point to there curiously and ask: "General Ma, why are there houses there? Could it be the guard post set up here in the city?"

Ma Zhou looked in the direction of Han Qi's finger, and then a solemn expression appeared on his face and said, "There is actually a temple there, and it also has a deep relationship with our Song Dynasty!"

"Medal? What temple?" Han Qi couldn't help but ask curiously when he heard Ma Zhou's words.

"This temple is called Invincible!" Ma Zhou said solemnly again, especially when he said the word "Invincible", he also had great admiration in his expression.

"Invincible? What a big mouth... Oh! It turns out it was him!" Han Qi wanted to mock the name of the temple for being too arrogant, but then he thought of something, and his face changed immediately. Others called it naturally and could not bear the word "invincible", but there was one person who was recognized as invincible by the Song and Liao countries.

"Yes, the one who worships Yang Lao Linggong!" Ma Zhou looked at the temple in the distance with a stunning look. As a military general, Yang Ye, Yang Lao Linggong has always been one of the military generals he admires the most, so he naturally respects the temple that worships him. He even went to worship himself before.

"No, didn't Mr. Yang die in Chenjiagu? Why is his temple located here?" Han Qi suddenly thought of something and asked curiously again.

When Emperor Taizong of Song sent troops to the north, three large armies attacked the Sixteen Prefectures of Yanyun. However, Cao Bin of the Central Army was not good at the outbreak, and the Western Army led by Pan Mei could only retreat. However, in order to cover the people of several states, Yang Ye took the initiative to leave behind. Originally, Pan Mei should have led his troops to support the Chenjiagukou, but Pan Mei retreated first, resulting in no one responding after Yang Ye completed the task of shutting down the rear.

Without reinforcements, Yang Ye could only lead his troops to fight the Liao army. In the end, everyone around him died in battle, and even his second son died by his side. However, Yang Ye broke into the enemy alone and killed hundreds of Liao army. Later, he was captured due to his war horse injury. However, Yang Ye would rather die than surrender and died after three days of hunger strike. Chenjiagu belongs to Lanzhou, which is quite far from Gubeikou.

"The transshipment officer didn't know that Old General Yang was extremely brave and brave. He had the courage to stop him with a sword. He had been known as "invincible" in the army. Before his death, he even killed several generals of the Liao army and killed hundreds of people. For a time, the Liao people were also intimidated by the reputation of the old general and wanted to surrender the old general, but the old general finally went on a hunger strike, which made the Liao people respect his courage and loyalty. So later, the Liao people set up an Invincible Temple here, which enshrines Yang Lao Linggong." Ma Zhou explained again immediately.

"But why is it here, not at the mouth of the Chenjiagukou where the veteran general died in battle? Is there any allusions in it?" Han Qi asked in confusion at this time.
