"That's great, I'll take the transporter around the neighborhood!" Ma Zhou heard Han Qi's words and immediately said excitedly, since he came to Gubeikou, he has always been worried, mainly because the Great Wall of Gubeikou is very damaged, and the troops in his hands are very limited.

Gubeikou is the Great Wall between Shanhaiguan and Juyongguan, it is divided into four sections, respectively, Wohu Mountain, Panlong Mountain, Jinshanling and Sima Tai 4 city sections, these four city sections are mostly built on the mountain ridge, there are very few roads that can be passed, and between Wohu Mountain and Panlong Mountain, there is just a passage, and the Great Wall sets up a city at this pass, guards this passage to death, and here is also the main place where Ma Zhou and others are stationed.

"Please see, this urn city is just located on the passage of the Great Wall, and the mountains on both sides have the Great Wall, and if the army wants to cross the Great Wall, it must pass through here, and the terrain here is easy to defend and difficult to attack, if the enemy attacks strongly, it will inevitably pay several times the casualties!" Ma Zhou took Han Qi to the urn city at the pass, and then introduced him.

Han Qi was also looking at this urn city built by the Northern Qi Dynasty at this time, this is a pure military fortress, there are no people living in the city, the whole city is not big, but it is shaped like a big urn, and the pass is tightly blocked, even if the enemy kills into the city, the defenders at the head of the city can also seal the enemy army in the city and calmly destroy it.

At that moment, Han Qi followed Ma Zhou into the city, and then climbed the city wall to look around, but when he saw the Great Wall on both sides, Han Qi couldn't help but sigh secretly, only to see that the Great Wall walls on both sides had already been dilapidated, and some of the city walls had collapsed and could not play a defensive role at all.

Even the urn city under Han Qi's feet seems to look good on the outside, but when they climb to the top of the city, they find that there are many places in the entire urn city that are very dilapidated, and as far as Han Qi knows, there was originally a Liao army stationed here, but the Liao country did not attach importance to it, and the Liao army stationed here mainly collected taxes.

"This section of the Great Wall was almost all built by the Northern Qi Dynasty in order to guard against the Xi people outside the country, so it is also called Xi Pass, the national strength of the Northern Qi Dynasty was not very strong, the construction of the Great Wall was mainly made of bricks and soil, and it was not very strong, and later the Sui and Tang dynasties did not pay much attention to the Great Wall, so it has not been well repaired, not to mention after being occupied by the Liao State, so after so many years, this section of the Great Wall has also collapsed in many places, if it is not repaired again, I am afraid it will be embarrassing." Ma Zhou spoke again at this time.

"In addition to the Xi Pass under our feet, are there any other passages on the Great Wall?" Han Qi finally asked at this time.

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

Han Qi also looked in the direction pointed by Ma Zhou, and found that the other party was pointing to a dense forest, which made him stunned, but then he found that 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 over there?" ”

The city wall of Xiguan is not very high, and it is summer at this time, and the trees are very lush, so the trees on the river bank also block the river surface, and Han Qi can't see the river surface from the position where he stands, but because the river is not far away, the sound of water can be clearly heard at the head of the city.

"Yes, there is the Chaohe River that crosses the Xijin Mansion, this river is from the territory of the Liao State through the Gubeikou, and then flows through the city of the Xijin Mansion, because the Chaohe River is turbulent, the sound of the water is like a tide, so it is named, but it is also this river that cuts the Great Wall into two sections, if the Liao people go south, even if we defend Xi Pass, the other party can also go down the river and reach the city wall of the Xijin Mansion!" Ma Zhou was also a little helpless at the moment, Xi Pass was indeed guarding the land route, but the water route was not within the defense range of Xi Pass.

Han Qi also frowned when he heard this, of course he knew that the Chaohe River almost all relied on this river for water intake over there, but he didn't expect that the Chaohe River actually flowed from Gubeikou, and with this river, there was also a huge gap in the defense line of the Great Wall, even if the Liao people were not good at water warfare, but after all, it was a big hidden danger.

"General, if the Great Wall is to be rebuilt in the future, the last general thinks that the scope of this Xi Pass can be expanded, and then the Chaohe River will also be included in the city, so that Xi Pass can cross the Chao River, and a sluice can be set up on the river, if the enemy comes and falls, no boats will want to enter or exit after the sluice falls!" At this time, I saw that Ma Zhou hesitated for a moment, and finally suggested it.

Han Qi didn't answer immediately when he heard Ma Zhou's suggestion, but pondered for a moment before he stepped forward and said, "Let's go, you take me to the Chaohe River!" ”

Ma Zhou heard this and immediately agreed, and then the two of them went down the city wall together, and then walked towards the tide river, Xi Guan was originally on the side of the tide river, the distance between the two places is not more than a mile, so the two walked directly to the river, only to see that the woods here are extremely luxuriant, and most of them are tall paulownia trees, just for the convenience of getting water, so a small road was built from Xi Pass to the river.

"In the past, the Liao army was stationed in Xiguan, and collected heavy taxes on the merchants who came and went, in order to evade taxes, many merchants took risks, loaded the goods on ships and crossed the Great Wall from the Chaohe River, in order to prevent the soldiers of Xiguan City from discovering, they also deliberately planted a large number of paulownia trees on the riverbank, the maple trees grow fast, and the trees are also tall, just blocking the sight of the head of Xiguan City, so that they can not be afraid of being discovered by the Liao army during the day." Ma Zhou introduced to Han Qi as he walked at this time.

Han Qi was also amazed when he heard this, he thought that it was normal for the trees to flourish by the river, but he didn't expect that it was specially planted by those smuggling merchants, which was a strange story, but now that Xi Guan has fallen into the hands of the Great Song Dynasty, these trees will definitely be cut down in the future.

After a while, Han Qi and Ma Zhou came to the river, and Han Qi also roughly estimated the distance, it was indeed very close to Xi Pass, and it was completely possible to expand the area of Xi Pass and include the entire Chaohe River, after all, the other side of the Chaohe River is a mountain cliff, which is also very suitable for building a city.

"This section of the tidal river is relatively narrow, after all, there are mountains on both sides, which causes the river to flow very fast from here, and there are many boulders and reefs under the river, and the smuggling merchants often have ships wrecked and people die, so except for some experienced old river workers who are familiar with the local water conditions, ordinary people do not dare to sail from here." Ma Zhou introduced again at the moment.

"Yes, yes, General Ma's suggestion is very pertinent, if Xi Pass can be extended here, the defense of Gubeikou will also 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 also very happy and modest, but at this time, Han Qi suddenly found that a corner of the eaves was exposed on the hillside near the riverbank, which made him also very curious and pointed there and asked: "General Ma, how is there a house there, is it a sentry set up here in the city?" ”

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

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

"The name of this temple is Invincible!" Ma Zhou said solemnly again, especially when he said the word 'invincible', his expression was also full of admiration.

"Invincible? What a big mouth...... Yikes! It turned out to be him! Han Qi originally wanted to laugh at the name of the temple that was too arrogant, but then he thought of one thing, and immediately his face changed, others called it naturally the word "invincible", but there was one person who was recognized as invincible in Song and Liao.

"Yes, it is Yang Lao Linggong who is enshrined in the temple!" Ma Zhou looked at the temple in the distance with a look of fascination, as a military general, Yang Ye Yang Lao Linggong has always been one of the military generals he admires the most, so he naturally has great respect for the temple dedicated to him, and even went to worship in person before.

"No, didn't Old Yang Linggong die in Chenjia Valley, why is his old man's temple set here?" Han Qi suddenly thought of something at this time, and asked curiously again at the moment.

In that year, Song Taizong sent troops to the Northern Expedition, and the Third Route Army invaded the sixteen states of Yanyun, but Cao Bin of the Middle Route Army was unfavorable, and the Western Route Army led by Pan Mei could only retreat, but in order to cover the people of several states, Yang Ye took the initiative to ask to stay behind the broken queen, and Pan Mei should have led the troops to meet at the mouth of Chenjia Valley, but Pan Mei took the lead in retreating, resulting in no one answering after Yang Ye completed the broken task.

In the case of no reinforcements, Yang Ye could only lead the troops to a decisive battle with the Liao army, and finally the people around him were killed, even his second son died by his side, but Yang Ye was killed in the enemy alone, cutting hundreds of Liao troops, and was later captured because of the wound of the war horse, but Yang Ye would rather die than surrender, and died of hunger strike for three days, and Chenjiagu belonged to Lanzhou, which was quite far away from Gubeikou.

"The transfer envoy does not know, the old general Yang is brave, a knife has the courage of ten thousand people to stop, as early as in the army there is the name of 'invincible', before his death is to kill several generals of the Liao army, hundreds of people, for a time the Liao people are also afraid of the prestige of the old general, this is to recruit the old general, but the old general finally died of hunger strike, which makes the Liao people also respect his bravery and loyalty, so later there are Liao people here to set up an invincible temple, which enshrines Yang Lao Linggong." Ma Zhou explained again at the moment.

"But why is it here, not at the mouth of the Chen family where the old general died in battle, is there any allusion in this?" Han Qi still asked a little puzzled at this time.
