"Can you take a boat to Yalu Mansion next time?" Shao Siwu had a sudden idea and asked on the banks of Wugu River.

Isn’t it much faster to march by land from Lushun County, which was first developed, the most populous, relatively prosperous and the most convenient transportation?

The speed of the ship is four or five times that of your land marching, and the consumption is very small. You don’t have to worry about the enemy’s sneak attacks or setting up ambushes or other things. Wouldn’t it be nice?

"Your Highness is wise and sensible, and I will admire you." The envoy of the Pinghai Army Zhao Zonghui said flatteringly: "Just send someone to investigate the hydrology along the way, record the wind direction and ocean currents, and try a few more times, it should be successful."

It is said that the Imperial College has just established a navigation department and recruited more than a dozen students, all of whom have transferred from mathematics and engineering. This subject was built by a saint and was involved in the compilation of the first set of textbooks.

The sage's love for the Navigation Department is well known. He even personally fixed multiple terms, such as "ocean current", "speed", "sea mile", etc.

To understand the direction and speed of near-shore currents is what Ping Navy has been doing, and some people have also sacrificed for this.

In the face of headwinds, the best route is to float along the direction of the current.

Ocean currents are fast and slow. Fisheries and complex weather phenomena will be formed at the intersection of cold and warm currents. These must be understood slowly. The Pinghai Army even requires that it find out how many fishing grounds are located near the sea and what month is the fishing flood every year.

It is best to find out which sea area these fish lay eggs, which sea area they grow and grow after the eggs grow. Which fish has the largest number in each fishing ground? Can it be caught by fishing nets, or should it be fished by fishing? The concepts of shallow water fish, deep water fish, cold water fish, and warm water fish have also been proposed, and you must slowly understand them - if possible.

The ocean is also a very important ranch. If it were not for the limitation of refrigeration technology, it would be a very important source of protein supplements, which can reduce food consumption - especially cold-water sea fish, which is large in size, high in yield and high in fat content. It is not as hungry as freshwater fish, and it is still very valuable.

Shao Sheng of Daxia is now obsessed with participating in the compilation of various textbooks. Three points and one line every day, which is very regular: Gan Tangyuan plays with his wife - Guanfeng Hall listens to politics or enriches the content of the textbook - Gan Tangyuan plays with his wife, is really a role model in the world.

"I think the boat is a good thing now." Shao Siwu said with an excited look on his face, and silently said in his heart: If there was no shipwreck drowning.

"Your Highness, should you set off to head north?" Fu Cunshen walked over and asked after inspecting the military camp.

Although Fu Cunshen was the de facto commander, in name, he was the "deputy" commander of the commander, and Shao Dacai was the commander of the army appointed by the court. He did a good job in the scene, not like an ordinary rebellious martial artist, and was a wise man. In the future, no matter how the court changes, the Fu family should be able to enjoy wealth.

Their place is now called Wugucheng, which is one of the famous cities in Goguryeo and one of the five mattresses. It is a transportation node city that enters the "Pyongyang Road" of the royal capital of Goguryeo from Liaodong.

Simply put, Wugucheng is the northern gate of Pyongyang, the capital of Goguryeo, and its gains and losses are related to the safety of Pyongyang. Yu Zhongwen of the Sui Dynasty and Zhang Liang of the Tang Dynasty both fought here.

Wugucheng is the Fenghuang Mountain City in the southeast of Fengcheng, Liaoning in later generations. It is located in a canyon between Dongdadingzi and Fenghuang Mountain. The city is surrounded by the Ruo River and the Ruo River tributaries, forming a natural moat. The southern half of the mountain city uses the cliffs of Fenghuang Mountain as a natural city wall, and is built with wedge-shaped stones between the low parts of the mountain and the cliffs and valleys.

The mountain city is thirty miles away, with a magnificent momentum, "a vast and vast place in the middle, and can be garrisoned 100,000 people." Until later generations, there were still some remaining parts of this mountain city, which shows its solidity.

Wugucheng geographically belongs to Huanzhou under the jurisdiction of the Yalu Mansion, Xijing, Bohai Kingdom. Of course, this was included in them after their expansion. Even during the heyday of the Bohai Kingdom, it did not belong to them. However, when the country's power was declining, it was a strange thing to expand its territory.

The entire Yalu Mansion governs the four prefectures, Huan, Feng, and eleven counties, and governs the Shenzhou, which is now Linjiang City, Jilin Province.

To the west of Shenzhou is the main prefecture, and the prefecture is located in the area of ​​Xinbin, Liaoning.

The south of Shenzhou is Huanzhou, which is under the capital of the old capital of Goguryeo, which is now Ji'an, Jilin.

The north of China is Fengzhou, and the prefecture is located in the ancient city of Yushuchuan, Jingyu County, Jilin Province.

From the geographical distribution of the four prefectures and eleven counties, we can see that in the middle of the Bohai Kingdom, a large area of ​​land near the sea in the south did not belong to them. That is, after the Tang people gradually retreated, they eroded step by step, expanded south little by little, and finally arrived at the sea, and even the western Liaoning area.

Until the rise of the Khitan, the two sides fought for this uninhabited land after the Tang people withdrew. The Bohai Kingdom gradually became unable to do so. In the end, not only did they spit out the land obtained from expanding territory, but they also lost all the five capitals and fifteen prefectures of the old capitals and the three solo prefectures.

After Shao Siwu and Fu Cunshen led their army to Wugu City, they were very concerned about this once-democratic land.

However, they still asked for the Bohai Kingdom and did not intend to do anything for the time being. They just sent scouts to investigate the mountains, rivers, and maps. They delayed a lot of time until the Bohai Kingdom's envoy arrived and then restrained a little.

"Let's go, go to Gaimu City first." Shao Siwu said.

After saying that, he said to someone beside him: "Along the way, Pei Shaoqing needs to contact you more to provide food, medicine, arrows, chariots and horses."

When Pei Yu heard this, he smiled slightly and said, "It's easy to say, it's easy to say."

The Bohai Kingdom implemented the system of three provinces and six ministries, namely Zhengtang, and promulgated the imperial edict, and the three provinces of Zhongtai. Zhengtang Province also governed the six ministries of loyalty, trust, etiquette, righteousness, benevolence and wisdom.

Pei Yan's father, Pei Yan, served as a junior supervisor of the Cultural Relics Academy, and has retired - the Cultural Relics Academy, which is equivalent to the Secretariat of the Tang Dynasty.

Pei Yan's career was even smoother than his father. He had been the junior supervisor of the Wenju Academy and was transferred to the Ministry of Trust several months ago - this position was equivalent to the Minister of Works of the Tang and Xia dynasties.

As for why Pei Yan was sent as an envoy to the army, it was actually very simple. He was a diplomat who was professionally engaged in the Bohai Sea. He was very literary and eloquent. His father Pei Yan went to Japan twice, and his son inherited his father's business, which was quite normal in this era.

The Pei family is also a scholarly family in Bohai Kingdom.

Pei Fengshuo was well-educated and beautiful, and was good at writing poetry. When he was on his way to Japan, Japanese Aobara Sugawara Daoma once presented his poem "Seat the Bohai Ambassador's Homecoming in Summer" and "Thoughts on the Picture of Ambassador Pei, seeing Bohai Ambassador Pei".

Pei Yan is also good at writing poetry and is known for his gorgeous rhetoric.

Unfortunately, such a person is actually a peacemaker! It is not a good sign that King Bo Hai sent him to the Xia army to serve as a liaison officer.

"Then let's set off. Send the order and beat the drum!" Shao Siwu wore a big red military uniform from the Shao family, tying his head and placing his forehead, bowing his left and right sword, making him look like Shao Shude's youthful appearance.

"Dongdongdongdong..." The drums kept ringing.

In Wugu City, soldiers emerged one after another, and tens of thousands of infantry and cavalry lined up by the river, majestic.

"Kill! Kill! Kill!" After the gathering of troops, the soldiers hit the ground with their spears and shouted loudly.

Pei Yan was shocked.

Perhaps because of the strong murderous aura, his elegant and calm image was damaged. He was a little displeased and muttered in an inauspicious voice: "Vulgar Martial Artist."

Shao Siwu had a sharp ear and heard it, but he didn't say anything, but he just sighed in his heart: Once upon a time, the Marine was a wild savage who was too wild to be wild, fierce and arduous to fight, how could he look like this? Marine was called Sushen in ancient times, Wuji in the Northern Wei Dynasty, Wuji in the Tang Dynasty, Sushen in the Song Dynasty, or Jurchen in the Song Dynasty. Perhaps later generations never thought that the middle and upper classes of this country were praised for their poetry, books and articles? Or in the northeast, they were very despised by their blood relatives, the Wu Jurchen Hei Water Five tribes, often attacked and constantly spreading to the north, driving the weak-like Wild Jurchen relatives to both sides of Heilongjiang.

Don't break their state, never.

After the army set out, we headed north along the Changling Yingju Road-Pingyong Road.

This is an east-west main post road in the Bohai Kingdom. It is roughly from Yingzhou to Yanjun City, also known as Yizhou City (now Yi County, Liaoning). It was built in the second year of Zhenyuan of Emperor Dezong of Tang Dynasty and has now been abandoned.

The city of Yanjun went southeast to Ruluo guarding the city of Chae, then crossed the Daliao River, and headed straight to Liaoyang, Andong Protectorate, for a total of 500 miles.

It takes Liaoyang northeast, passes through the original Gaimuzhou, and reaches the Changling Prefecture of Bohai Kingdom, with a total length of more than 800 miles.

Bohai Kingdom once spent a lot of effort to renovate this road of more than 1,300 miles. The main road has 24 large stations, and there are also small stations on the branch line, with many merchants and travelers.

There is also an office road from Changling Prefecture to Xijing Yalu Prefecture, and now the army is following this road.

While walking, Fu Cunshen still sent a large number of scouts, scattered within 50 miles of the army. After seeing the Bohai people who followed the army looked at it, they all exclaimed: They were so alert to march in the inner line of the Bohai Kingdom, and they deserved to be the Great Xia soldiers.

On July 26, they received news that the Longwu Army envoy Liu Xiu had repeatedly defeated the Khitan after a great battle and had entered Liaoyang City.

Shao Siwu, Fu Cunshen and the other two breathed a sigh of relief.

If the Dragon Martial Army is gone, they can only retreat.

"I told the entire army that General Liu captured and killed 50,000 Khitans, advanced to Liaoyang, and won a great victory." Shao Siwu ordered.

Cao Yijin took the order and left. After a while, the eight thousand soldiers of the army cheered warmly. Before leaving, two thousand soldiers left in Wugu City, in the name of guarding supplies.

Fu Cunshen smiled. Compared to the saint, His Highness King Zhao was more exaggerated.

The people of Bohai also knew. Pei Yan and his followers looked at each other in a glance. Is it true or false?

If it is fake, then perhaps the Longwu Army has been destroyed, at least the progress is not going well. The Bohai Kingdom has sent 30,000 troops to provoke the Khitan, but it is in danger.

If it is true, the Bohai Kingdom seems to be quite dangerous.

With this idea, Pei Yu did not feel like writing poetry in the magnificent mountains and rivers. He secretly sent two followers to report to local prefectures and counties, and then reported to Beijing directly.

The Xia people naturally didn't care what the Bohai people thought. When everyone was excited by this news, everyone's steps became much lighter.

On the 29th, he arrived in Gaimu Prefecture, which was originally Gaimu County in the Han Dynasty and Gaimu City in Goguryeo. After the Tang Dynasty captured it, it was renamed Gaimu. This was the first time that the name Gaimu appeared in history. It was located in Tashan Mountain City, Chenxiangtun Town, Sujiatun District, Shenyang.

When we get here, the army has two directions to choose.

One is to the southwest to Liaoyang, the other is to the northeast to Hezhou, Changling Prefecture (now Shancheng Town, Meihekou City, Jilin).

They chose the second route.

Because the army was almost all infantry, with only more than a thousand cavalry and lacked large chariots, the endless Liaoxi Plain was in the west, and I was afraid that the outcome would be bad if I went there. It would be better to continue walking in the mountains, and the Khitan cavalry did not dare to come. In this way, go to Hezhou first, obtain key supplies, and then look for other directions.

In addition, if you really want to move westward, you can also find craftsmen in Changling Mansion, build vehicles, and prepare for the advance.

"Wang Yanzhang!" Fu Cunshen ordered.

"The last one will be here!"

"You will lead two thousand infantrymen, five hundred cavalrymen, two thousand Bohai Masters, and take control of Gaimu City for three months without any mistakes."

"Abide by the order!" Wang Yanzhang was full of confidence and took the order and left.

His movements were very fast, and in just half an hour, the personnel were selected.

The cavalry were all his old subordinates, and the infantry of the Guide Army were also familiar with them. Among the more than 20,000 Bohai masters who followed the army, two thousand people who looked more powerful and brave were also selected.

Gaimuzhou is also in a semi-abandoned state, with the stone part still retained, but the rammed earth has collapsed to a bad state.

But Wang Yanzhang was not worried at all. The Khitans had the ability to attack and fight with you.

But then again, the Khitans are really likely to come and attack.

This city is only a hundred miles apart from Liaoyang. If Liu Xiu is still guarding there, he will help each other. If the city is renovated, it will be two sharp knives that are on the abdomen of the western Liaoning of Khitan.
