Li Shimin still left, took Li Xuanba's coffin, and under the escort of the Special Service Office, he followed a large merchant group of thousands of people in the Central Plains from Liaodong to Liaohe and went south along the Liaohe River to Beisha City, floated across Shandong, and finally returned to Hedong via the canal.

Li Xuanba's death was too sudden, even a little too weird. A top-notch hero in the army actually died in the hands of several unknown people in a chaotic dark night.

After reading the letter his father wrote to Chen Kefu to transfer them back to the Central Plains, he was suspicious.

He suspected that Chen Kefu was unwilling to let them leave, so he made the last move. Maybe Chen Kefu would not do this, but he was not alone. Behind Chen Kefu was still a group of people from Chenjiazhuang, especially Mao Yi and his father Mao Xi. These two people were both good at plotting people. He was very suspicious that the death of his fourth brother was the one sent by Mao Xi or Mao Yi.

Others only know that the Secret Service Department does not know the mysterious department of the Investigation Department, but Li Shimin knows that the Investigation Department is actually a department that is stronger and mysterious than the Special Service Department. The Jinyiwei, who is under the Investigation Department, is truly walking in the dark. They are not like the Secret Service Department, who are specializing in external affairs, they are internal and external affairs, monitor all the soldiers' surnames, and even help Chen Kefu suppress dissidents. Moreover, this mysterious power is only in the hands of Chen Kefu.

The two brothers knew that Chen Kefu was preparing to rebel. Now that they were going back to the Central Plains, they would undoubtedly feel that they were a risk. With Mao Xi's sympathy that only had Chen's in his eyes, it was difficult to guarantee that he would not take action. Once the seeds of doubt were planted in his heart, they would begin to take root and continue to grow.

With his vague understanding of the investigation character, he knew that the investigation character was everywhere and his strength was strong. It was too simple to kill Li Xuanba. Even it would not be difficult to kill him. When he thought of this result, he couldn't sleep or eat. He originally wanted to stay and attack Shi Wei to take revenge, but after he had this idea, he hesitated. After Chen Kefu persuaded him twice, he nodded to agree to return to the Central Plains.

When he first saw his father beggar go back to assist, he even thought about asking for several heavy cavalry and Mo Dao Bing from Chen Kefu to return to Hedong.

Mo Daoping and the heavy cavalry were both staying there, and later they were the commander of Mo Daoping. He knew very well how powerful these two soldiers were. He thought that if he led such two troops back to Hedong, he would definitely be able to pacify the bandits in Hedong in one fell swoop.

However, after he had the suspicion, he never mentioned a word again, even the meaning of taking a team of personal soldiers back. In the end, he stayed in Liaodong for a few days every day and stayed in the mansion without leaving the house for a day, fearing that the Jinyiwei of the investigation department would come to him.

Until he left, he saw that Chen Kefu did not send troops from the guard camp to escort the soldiers but sent the plainclothes of the Special Service Department. He felt mixed feelings in his heart. At this moment, he had lost all the admiration for Chen Kefu, and all he had in his heart was endless suspicion and barrier. The Li Shimin, who could rush forward with just one word at the beginning, was gone. Standing on the Liaohe Wharf and stepped onto the sailboat, he stared back for a long time, and then stepped onto the boat without hesitation.

Chen Kefu did not go to see Li Shimin in the end, and he had too many things to do, and his troops had gathered. The day when Li Shimin returned to the Central Plains was also the same day when his troops headed north. Li Shimin walked on a waterway and went down the Liao River from the ship. Chen Ke returned to the north gate, with more than 40,000 soldiers and horses riding horses and rolling north.

In Liaodong, Chen Kefu had the most abundant war horses, most of which were seized from the original Goguryeo. However, after alliance with the Khitan and mohé, he also traded several times with the two tribes and got back a large number of war horses. This time, Chen Kefu had not only a large number of cavalry, but also a lot of infantry. However, Chen Kefu had sufficient war horses in his hands, and all the infantry and horses became horse-riding infantry. During the march, not only did everyone have war horses, but they also had one person and two horses, and they were rotated to allow the army to achieve the fastest maneuver speed.

Although the troops were only transferred more than 40,000 in the end, many generals and schools were transferred. In addition to the seven counties and nine gates, most of the generals and schools in the entire Liaodong army were transferred. The army went north, passing Jinshan County, Gaimu County, Wuluo County, and finally arrived at the northernmost point of Fuyu County, Liluo County.

It was already March, and March in the Central Plains was the time when the grass grew and kites flew. However, on the grasslands in western Liaoning outside the border, it was still in the cold wind. However, although the weather was still relatively cold, it had passed the rain and snow season, and there were more sunny days.

Early this morning, a red sun hung in the east, and the golden light spread the entire grassland to a layer of gold. An army slowly appeared from behind the woods, and the cavalry was covered with the earth. The first one was a big black army flag, followed by a large Chen-character flag.

Under the commander's flag, Chen Kefu was wearing armor and straddled Qingsui. Next to him, there were dozens of generals surrounding him. After a full half month of march, Chen Kefu finally arrived at the Jinshi City, the northwesternest part of Liaodong. The army of more than 40,000 people could definitely start a major battle in western Liaoning. After destroying Goguryeo, as long as it was not a coalition force of various races, there was no tribe in the entire Liaodong, western Liaoning, and Haidong that could easily deal with the 40,000 elite troops of the Sui Dynasty and Liaodong.

In fact, Chen Kefu's speed of sending troops surprised Yu Juluo and others. From the decision to send troops to the end of the gathering of troops, it only took Chen Kefu a day. It only took him half a month to go from Liaoyang City to the Jinshi City of Fuyu County from the north.

Golden Lion City is not a mountain city like most cities in Liaodong, it is a city built on the grassland. Moreover, this is a new city. Originally, it was a earthen castle built by the Goguryeo people and was the front line for the defense of the Wei people. However, after Chen Kefu took over Liaodong, he sent people to build a city on the wedge tip where the four forces of Shiwei, Khitan and Mohé were converged.

This is not an ordinary city, not a earthen castle, nor a brick castle, but a stone castle. Tens of thousands of slaves were sent to use black gunpowder to open mountains and explode stones. They collected many stones from nearby mountains and transported them to this critical location to build a stone city.

Moreover, this stone city is different from ordinary fortress construction. This is a drawing produced by Chen Kefu himself. The entire stone city is a huge military fortress, which uses a prismatic fortress that was only built in the Ming Dynasty in later generations.

A prismatic bastion is a type of military bastion. Its essence is to turn the city from a convex polygon into a concave polygon. This improvement makes it possible for the attacking party to force more than one bastion surface (usually 2-3). The defense party can use cross firepower to perform multiple strikes.

Before the gunpowder era, the fortress walls were usually tall and reinforced with stone or bricks. Towers or horse faces were also set up to obtain additional firepower output. If anything, some particularly solid cities had more than one wall.

This design was introduced from Europe to China nearly a thousand years later. For Chen Kefu, who has a powerful crossbow and arrow equipment group, a solid fortress is the last base of advance in this intersection of all directions. The bastion is a new defensive formation that can maximize the advantages of the Liaodong Army's equipment and gunpowder. The bastion in Liluo City is a crown-shaped multilateral bastion. It has the same appearance as the crown and has prism-shaped edges.

With such a new type of shooting-free blind spot bastion, coupled with Chen Kefu's army's sufficient long-range shooting weapons such as crossbows, catapults, hand crossbows, bows and arrows, a conclusion was drawn after deductions by Chen Kefu, the generals in the army, and a group of new staff officers in the Staff Department.

If an ordinary siege is fought with one siege, then the defenders can hold on for half a month. If one siege is one siege, they can hold on for about a month. But if the Sui army insists on the Golden Lion City Castle, then as long as there are enough equipment in the city, they can handle 20,000 sieges for three months without falling.

If there are five thousand people, they can hold on for half a year. If there are ten thousand people, Chen Kefu can ensure that the bastion will never fall in western Liaoning. This is why Chen Kefu worked hard to build the Golden Lion City. He wanted to make it a wedge that was tightly nailed into the Khitan, mohé, and Shiwei.

You can attack and retreat at any time, and you cannot urge you to do so.

Golden Lion City is the name given by Chen Kefuxin, using the golden lion banner of the Liaodong Army's past central army. Golden Lion City is actually not a city, but a six-city city. It is scattered on the grassland like a six-pointed star.

The star tip in front is the Golden Lion Castle, with a circumference of three thousand steps and a maximum of 150,000 troops. The city consists of military camps, equipment warehouses, craftsmen's barracks, various equipment workshops, grain warehouses, etc. The entire castle is all military for use, and any non-military personnel are forbidden to enter. This is a city of war. On the various prism-shaped castle surfaces of the castle walls, huge chuáng crossbows, catapults, and Fuyuan crossbows, and catapults that specialize in casting thunders. The most common types of troops in the castle are not cavalry, but engineers. According to Chen Kefu's plan, this city will ensure that 5,000 soldiers are guarded all year round, and engineers will never be less than two thousand.

In this city, there is also the most confidential gunpowder production workshop of the entire Liaodong Army. Chen Kefu's most confidant general Chen Qing personally took charge of the Golden Lion Castle. In addition to the largest castle, there are two small castles on his left and right. These are the Silver Lion Castle and the Tong Lion Castle, and they are also two pure military fortresses. Their establishment exists as the acropolis of the Golden Lion Castle.

Behind the three fortresses in front are two towns where residents live, namely Shishi City and Mushi City. The county town of Jinshi County is also in one of the city Shishi City. Most of the immigrant Han military households live in Shishi City, while the original surnames and slaves of Liaodong live in Mushi City. At the end, there is a city of Iron Shishi City, which is a mall, which is specially used for local surname transactions and tribes from all directions to trade here. The city is full of inns, various brothels, warehouses, and shops.

Chen Kefu's three layers of the chao army, civil and merchants were separated, which made the other five cities acropolis of the Golden Lion Castle. On the other hand, it was also to strengthen the security of the Golden Lion City and prevent other tribes from getting involved.

There are six cities, the Golden Lion City is the largest city of 3,000 steps, the Silver Lion and Copper Lion Acropolis is one thousand steps Stone City. The Stone Lion and Wood Lion Ermin City are just two thousand steps in a circumference, and the Shopping Mall Iron Lion City is a big city with a width of 3,000 steps.

Golden Lion Castle, Silver Lion Castle, Copper Lion Castle, Stone Lion City, Wood Lion City, Iron Lion City, six cities arranged like a six-pointed star are scattered on the grassland, making the originally endless grassland suddenly have a string of the strongest fortresses. At the same time, this place has become the most dazzling string of pearls on the northwest side of Liaodong. This place belongs to Liaodong's narrow and deep Khitan, Shiwei, and Han Song. In normal times, it has also become a forefront of commercial and trade cities. Merchants of all ethnic groups gather here to trade here.

The general Central Plains caravans basically end here. If they go further further, they have reached the hinterland of various tribes, and only some adventure small caravans will enter.

In this small but important northwest land in Liaodong, in addition to these six castles, there are also a large number of guardhouses on the frontier border with the three tribes. These small guardhouses are called forts, but they are actually beacon towers. Each guardhouse garrison is generally built with a high-rise building, and beacon towers are set up. Once there is an alarm, the beacon fire will be ignited and transmitted backwards and early warnings. Because the grassland is flat, Chen Kefu is on the border, and every time he is in the same way, he will be able to use it.

A garrison fort is set up thirty miles apart. The beacon fire sets smoke during the day and sets fire at night. If nothing happens, ignite a pillar of beacon smoke to show safety. If there is a warning, two pillars of beacon smoke will be raised. If it is extremely urgent, three pillars of beacon smoke will be raised. In the fort, not only are beacon smoke warned, but all are equipped with Yima. Once there is a policeman, after lit the beacon fire, the Yima will be sent to the next station to report which side of the police is coming, the specific number and location, etc., and use this station to pass on one station.

Chen Kefu's troops were dozens of miles away from the Golden Lion Castle, and three pillars of beacon smoke were already lit in front of him. This was a transmission to the rear that a large army arrived. Sure enough, a black line appeared in the depths of the grassland.

"Master, some troops are coming." Shen Guang, who had just been transferred to Modao Camp to take over Li Shimin's position, pointed at the front.
