As soon as the former team of Great Song cavalry left, another team of Great Song cavalry came from another direction. The commander in charge was not like the fighters who kept shooting. Shooting was not his job, at least not his important job.

When the brigade rushed to a small earth slope, the commander stood up in the stirrups. Sure enough, a silver-like river appeared in the vision ahead. The commander shouted loudly: "After rushing forward to the riverside, go downstream along the river. There are troops supporting us."

After shouting, the commander sat back on the saddle and acted with the brigade. With a river, it was easy to deal with. There were very few landmarks in the vast wilderness, and the vast land was wilderness. Until the Song Dynasty chose rivers as a signpost to guide them, the world north of Yinshan suddenly became clear and clear.

Facing the Song army, which was like a pack of wolves, Mongolian riders came to intercept them. These brave men were quickly sprayed to death by the trolls in the hands of the Song army. The Song army did not pause at all and ran downstream along the river.

As soon as this team of Song troops left, another team of Song troops came from other directions. Two waves of Mongolian tribes were already in a mess. The women who were tidying their clothes and doing work all took their children back to the tent. The tribes returned to the ancient yurts made of their yurts.

Gu Liyan refers to a collection of yurts composed of circles of yurts formed by wise elders and tribal leaders when Mongolian tribes were stationed, and Gu Liyan did not cross the circles when they lived in circles.

The young and middle-aged people rushed to the area in the center of Guliyan, anxiously waiting for the tribal leaders and elders to make the latest decision. At this moment, another team of Song cavalry came from a distance to the riverside. The speed of the cavalry was not fast, and there were cannon carts pulled by horses in the middle of the group of people.

Seeing the various Gu Liyans with tight defenses, the Song cavalry stopped beside Gu Liyans where they passed. The artillerymen jumped off their horses, quickly installed artillery, and opened fire violently at the yurt. After the gunner poured out the shells at the fastest speed that the cannon could withstand, they simply put away the cannons with metal gloves filled with asbestos insulation. They jumped onto the horse and continued to march towards the river.

Like previous experience, once the Mongolian tribes retreated back to the ancient liyan, they would choose to defend the enemy. The Song Dynasty cavalry did not encounter interception by the Mongolian cavalry. The gunners were watering the artillery while acting. When they walked to another ancient liyan, the artillery cooled down, and the Song Dynasty cavalry stopped and launched a new shelling attack on the nearby Gu liyan.

The commander of the Song army was very nervous, but he could not tell at all on his face. He calmly commanded the battle. This was a tactic summarized through a large number of practical combat. The Mongolians' response was the same as the previous experience of the Song army. Once they entered the Guleyan, composed of their own tribe yurts, it was like a piece of loose sand. The Song army followed the huge gap between Guleyan, and was completely attacked by Mongolian cavalry from different tribes.

After the shelling, the Song army cavalry continued to walk along the river leisurely. After walking for a while, the Song army commander finally felt relieved. At this time, even if the Mongolian cavalry came out in full, they could not threaten the Song army carrying artillery. The Song army that had gone along the river before did not return to the camp directly. They stopped downstream to repair. After receiving the message transmitted by the signal flare, they were able to go up the river in a very short time and attack the pursuing Mongolian cavalry.

At this time, the sun began to slant westward and moved slowly against the skyline quite close. May of the Song Dynasty was about the summer solstice, and the day was extremely long and the night was very short. To the north of Yinshan Mountain, there were many places north of Youzhou. The summer here did not have the half-year extreme day in the Arctic where the sun never set, but there was also a long day.

In the same direction as the previous three waves of cavalry attacks, there were three large Song cavalry ready to go. The cavalry division that launched the attack organized a total of six waves of attacks. Although the starting points were different, the direction of attack was exactly the same. The Song cavalry would pass through the Mongolian tribe's garrison, rushed to the riverside, and down the river. The long day just provided the Song army with sufficient light for the attack.

In such summer days, the three cavalry divisions of the Song army launched an attack on their enemies. Far away from the river, 30,000 Song army infantry were advancing towards Helin. A group of neat Song army marching teams were guarded by cavalry on both sides, and cavalry communicated with each other. A large number of horses and mules pulled carts to provide transportation supplies for the troops. The troops heading to Helin were standard infantry divisions, and the more attractive were the four-legged mules and horses.

Wu Ziyang, the head of the Yinshan War Zone, and Yang Tiexin, walked side by side. Wu Ziyang was obviously excited, "Commander Yang, if we continue like this, we can come to Helin the day after tomorrow."

This plan was drafted by Yang Tiexin, and it was impossible to tell from the outside that he was particularly excited. First, he was silent for a while, and Yang Tiexin replied: "Let's talk about it when we are here. This time we can walk so smoothly because we have not encountered the enemy's harassment troops. If it were before, news of the Mongolian cavalry surrounding and harassing were heard from various military stations."

"Will it be effective to sweep along the river?" Wu Ziyang was even more happy. Even though he believed that the combat effectiveness of the Song army was stronger than that of the Mongolian army, Wu Ziyang still felt that the Song army's cavalry was not as good as the Mongolian cavalry. This had nothing to do with knowledge or position, and was just an inherent concept caused by the Song Dynasty's incorrect knowledge of the north for more than 300 years.

Yang Tiexin shook his head and said nothing. After repeated deductions, all plans were already detailed enough for an old soldier. At this time, only a good implementation plan was needed. At least until now, Yang Tiexin was quite satisfied. Then three cavalrymen rushed to Yang Tiexin, they held the tall war horses and hurriedly reported: "The vanguard troops encountered an enemy attack from Helin."

Wu Ziyang felt nervous and then became excited. The troops would definitely fight with the Mongolian army, and now they finally met. Turning to look at Yang Tiexin, Wu Ziyang felt a stern. He saw that Yang Tiexin, the commander of the Yinshan War Zone, seemed to have turned into a sharp blade. Although his tone was plain, he was extremely firm. Yang Tiexin asked: "Is it the Mongolian army that drove out from Helin?"

"Yes. It's certain that it was the Mongolian army driven from Helin." The correspondent replied decisively.

"Go." Yang Tiexin said desperately.

Looking at the cavalry's speeding backs, Wu Ziyang thought Yang Tiexin would say something. Unexpectedly, Yang Tiexin just urged the mount to continue moving forward. Wu Ziyang hurriedly urged the horse to follow. However, Yang Tiexin still said nothing, just urged the horse to continue moving forward.

If it was in Henan, it would be completely dark at around 9 pm during the summer solstice, and it would be dark at around 4 pm the next morning. In Mongolia, the night time was even only about five hours. Wu Ziyang felt that he had just fallen asleep and was awakened by the movements around him, it was already light. When he looked at the watch, it was not yet four o'clock in the morning.

I quickly got up and brushed my teeth and washed my face with a small amount of water. After breakfast, the troops began to go north. According to the distance of one military station of thirty miles, the current Song army infantry can complete three military stations every day, which is a marching 45 kilometers a day.

Starting from around five o'clock, at around eight o'clock, the central army where Wu Ziyang is located has completed the first thirty miles. After resting and rectifying, he arrived at the second military station at half past 11. During lunch, Wu Ziyang was happy. Sun Tzu's Art of War says that those who are interested in the generals are depressed, while those who are interested in the generals are half. That is to say, the army will marching fifty miles, and half of them will fall behind. If the army marchs for 50 miles a day, half of the army will fall behind. If they march for 100 miles a day, they will likely lose the generals who are leading the troops. With the current training and preparation of the Song army, they can easily march for 90 miles a day without any fallen people. Marrying at such a day length, they can even walk 120 miles a day. Such a marching speed is even no less than that of cavalry.

The troops were repairing at the military station. In addition to eating, everyone even slept for a little afternoon. When they set off in the afternoon, everyone was full of energy, but when they reached the next military station, their previous physical exhaustion was still revealed. Even Wu Ziyang, who was riding a horse, felt a little tired.

After arriving at the military station at 5 pm, the commanders of the vanguard were already waiting here. Yang Tiexin and his team had just entered the command center of the military station, and they immediately reported the situation.

"From the Mongolian army coming from Helin, our troops have been gathering and have retreated."

Wu Ziyang asked: "How far is He Lin?"

"Fifty miles." The commander replied.

Yang Tiexin said calmly: "I led a regiment here to continue advancing and build a military station twenty miles away from Helin."

"Commander, is this too risky?" the commander of the vanguard immediately persuaded.

"Soldiers are very fast. We just need to bring cannons. Maybe when we see us coming to Helin, the Helin guards may run away."

"Give up going to Jing and Lin?" Wu Ziyang felt that Yang Tiexin was too optimistic.

Yang Tiexin finally smiled, which was a knife-edge smile. "The Mongolians are different from us. If they can't hold on, they will leave. Moreover, our plan is not to occupy Helin this time. If they leave, we will burn Helin and withdraw our troops."

After hearing such a thorough attitude, Wu Ziyang stopped asking questions. The idea that Zhao Jiaren established for the Song army was not to conquer cities and territory, but to eliminate the enemy. If all the Mongols from north of Yinshan to the grassland were eliminated, whether Helin City existed would become a meaningless consideration.

From this perspective, Yang Tiexin did fully implement the Zhao Guanjia's ideas. As soon as he thought of this, he heard Yang Tiexin say: "President Wu stayed here and organized the revision of the pacification army."
