Liang Guancheng was covered in blood in the military clothes. Looking at the Khitan army chasing him, he bent his bow and arrow, and shouted loudly, shooting the leader in front off the horse. Turning the horse, Liang Guancheng said loudly: "The whole army obeys the order and returns to the city!"

The horse's hooves rang out, and more than a hundred cavalry rushed towards the city not far away.

Luo Ji saw it at the top of the city and hurriedly ordered to open the city gate and put Liang Guancheng and his party into the city.

When he went to the city gate to meet Liang Guancheng and returned to the city, Luo Ji asked anxiously: "How? Have you ever broken the Khitan army?"

Liang Guancheng took off his bag and said in a deep voice: "I set a fire in their military camp. All the birds went to put out the fire. I think I can't attack again today. After surviving today, the troops who rescued from other cities should come!"

"Yes, it's time to come!" Luo Ji looked outside the city. At this time, the red sun was rising and the grassland was shining with golden light. Several Khitan military camps two or three miles away were clearly visible, and some were in line in front of them.

When the two were training the imperial guards left by Xu Huaide, they were transferred from Gao Daquan's army to Zhang Kang's army. Luo Ji was still the commander of the battalion, and Liang Guan became the deputy. At this time, the commands of the Longyou army had been expanded, from a standardized infantry of 500 and a standardized infantry of 400, and the horse army was expanded into more than 1,000 mixed horse strife. Under the new organization, although Luo Ji and Liang Guancheng's military positions had not changed, the officials were promoted, which was incomparable to the previous commanders. The system of the battalion at this level was relatively simple. Except for the commander and deputy commander, there were only three people to assist them. The basic command level of the Longyou Army was set on a higher level.

After being scared by Xu Ping with cannons that day, Yelu Chongyuan sat in a big tent and stopped coming to the front line. Yelu Ren was hit by cannons several times, and once he injured his mount, but in the end he was shocked.

After a few days, Yelu Renxian finally figured out the layout of the defense line in front of him. With the new city and the old city in Yunneizhou as the center, it extends for more than ten miles north and south, and the city walls are connected, which is the middle section of the defense line of the Song army. The city wall built by Liu Jianji in the north extends about ten miles from the bottom of Yinshan Mountain, and the same is true for Zhenwu County in Cao Keming to the south, which is also ten miles.

The Song army completely blocked the Jin River, and the mountains on both sides were blocked, leaving a twenty or thirty-mile gap between north and south. The broken gap had no meaning to the Khitans. They did not dare to pass by the city without a strong wall that stretched for dozens of miles, and they still wanted to dig this Great Wall. For the Song army, the existence of these two sections of gaps led to the inability of the three armies to be connected together.

The biggest function of a solid wall is to transport troops and grain. The grain channels are within the wall. Once the north and south are connected, the three armies will become a whole, and the troops can be quickly mobilized within the solid wall. If they are not connected, the troops will be fighting. The solid walls only play a role in blocking the passage of the Khitan cavalry and prevent them from surrounding the city.

After finding out the arrangement of the Song army, Yelu Renxian suggested that it would be better to attack the middle section first. This is the main force of the Song army. Obtaining results will be beneficial to future negotiations. It is hopeless to only attack the city on one side, so starting from the middle wall, it will be demolished to the middle section by section. Demolition of the city walls extending from the old and new cities in Yunneizhou, leaving two lonely cities. Even if they cannot be captured in the end, the post-war negotiations can put pressure on the Song army so that the conditions for peace talks will not be too harsh.

The city wall system that extends out is a city with five miles and a city, and the middle is connected by a wall. The distance between five miles is exactly the cannons of the two cities that can cover the walls connected by the middle, preventing the enemy from concentrating their forces to attack the weak links in the middle.

Including the Yunneizhou New City built by Zhe Jimin, there are three cities to the north, and the three cities built by Liu Jianji are six cities, numbered by the earthly branches. The new city of Zhe Jimin is Zicheng, a city near Yinshan is Jicheng, and Luo Ji and Liang Guancheng are Yincheng.

The old city of Yunneizhou where Xu Ping is located is Jia City, and the city at the southernmost end of Cao Keming is Ji City, which is the southern section of defense line.

Yelu Ren first chose the northern end of the northern section as his main attack direction, namely Yincheng, which was guarded by Luo Ji and Liang Guancheng.

Yesterday, he attacked for one day. Although the artillery from two cities helped, the wall in the middle was still broken by the Khitan soldiers. In order not to allow the Khitan soldiers to siege from all sides, Liang Guancheng led his troops out of the city to sneak attack the Khitan military camp overnight. The result was not great, but setting a fire should be able to delay their siege for one day.

When he returned to the yamen, he left the armor and Liang Guancheng cleaned up. He went to the yamen to drink with Luo Ji, and was welcomed.

After drinking a few glasses of wine, Luo Ji said: "Zhe Junma has sent the military order from the Protectorate's Office to hold our foothold. Reinforcements will arrive in the next two days, so there are no need to panic. Now the Khitan troops are surrounding us. I wonder if the Protector will send troops to raid their retreat."

Liang Guancheng shook his head: "Now Khitan has no choice but to take our strong city. He just hopes to go out of the city to fight with them, and he is afraid that he will not send troops out of the city to fight with them. In my opinion, it is better to resist the city and defend it, just win them off."

After breaking through the strong walls in the south,
