When Yelu Maliu returned to the Houya, he still felt angry on his face. When Yelu Buhua saw it, he went forward and bowed and said, "Aweng, why are you worried?"

Yelu Maliu always liked this grandson and said casually: "A few days ago, the boys in Ningbian Prefecture crossed the river and ate. The Song people first occupied Tanglong Town, but they failed to attack and buried their bodies in a foreign land. I wanted to send troops to restoration, but King Xiao of Fengzhou insisted on it and could not argue. I just comforted the people from the department, but said that King Xiao was right. I broke my troops and went to sue the Song people again. How could I swallow this tone!"

Yelu Buhua smiled and said, "Why bother Ah Weng! I have also heard of this matter, it is all because of the guard's lack of eyes. The Song people occupied Tanglong Town and he went to fight, but he couldn't fight. Isn't he trying to die? I heard that the Song people were very sensible and just defended themselves. The border soldiers died of cold and hunger. This matter was not blamed by the Southern Kingdom. This lawsuit could not be won, and the appeaser department would just settle the matter."

Yelu Maluqi said: "You have always ignored political affairs, why are you so clear about this matter?"

Yelu Buhua said embarrassedly: "I have been doing business with peace of mind for a year and have made a lot of money. The leader of the Song people who had the accident this time was originally signed by Bingzhou. It was during his tenure that the fur yard was built, and our family also made a lot of profits."

Yelu Maliu pondered without saying a word, nodded after a while and said, "It turned out to be him."

Yelu Buhua learned from Du Zhongxiao's cargo yard in Bingzhou and built a place in Datong Prefecture. However, there were no tanning workers here, they just bought and sold raw and cooked skin. They came from various places in Khitan and sold them to Bingzhou for tanning mature skin, and then transported them back to Datong Prefecture to distribute Khitan areas. With this business, Yelu Buhua made a lot of money and was very proud this year.

The Khitans value money more than the Han people. They make money home just like their grandsons. Yelu Maliu was very pleased and felt that they were much better than being an official. Anyway, the Khitans value family background more seriously. Yelu Buhua didn't go out and actually became an official, and he could also be a high-ranking official.

Looking at his grandson, Yelu Maliu said, "When you ask about this, are you trying to make things worse?"

Yelu Buhua smiled and said, "This Du Guanren from the South is a businessman. How can we compare to making money with him and fighting with him? Although the place in Tanglong Town is remote, it is a great place between our dynasty and the South and Dangxiang. If we can use this negotiation to start business with Du Guanren there, we may make more money than the fur in Bingzhou."

Yelu Maliu laughed: "Good grandson, there is no place where the prosperous Bingzhou is. The land is barren and the people are poor and deserted, so where can you make money!"

Yelu Buhua shook his head: "When it comes to making money, Aweng is no match for his grandson. Making money is about doing business, not buying and selling goods there. As long as the goods from other places are transported there. According to Du Guanren's methods, there will inevitably be a good way."

Yelu Maliu looked at his grandson and smiled and said, "What's your idea? Just say it."

Yelu Buhua said: "Aweng asked me to negotiate with the Han family's husband together. If it was well said and there was money to make money, I would not mention this matter. If there was no good news, let the Han family's husband and the southern husband grind their teeth. Aweng just found a reason to refuse."

Yelu Maliu smiled and nodded, patted Yelu Buhua on the shoulder, and left without saying a word.

Yelu Gao’s family slaves and Yelu Buhua walked hand in hand on the desolate land, chatting and laughing. Both of them were from big families and had known each other for a long time. This time, Yelu Buhua helped Gao’s family slaves persuade their grandfather and tried to resolve the conflict with gentle means, which made them even more happy.

At this moment, the horse in front ran back and crossed his hands at Gao's slave: "Sir, there is a water spring ahead to camp, but I don't want the Song army to build a fort there. What should we do? Please give me some advice!"

The Gao family slave was stunned and hurriedly urged him to step forward. Not far away, he saw a small town standing there in the height of the front. He hurriedly asked the guide beside him: "How far is this far from Bietou Village? How could the Song army build a fortress here?"

The guide said, "Sir, this place is more than 30 miles away from Biedouzhai. There is a hole connecting the northern grasslands and a water spring, which is an important place within a radius of dozens of miles. Since the Song army rebuilt Biedouzhai, it will inevitably build forts in these key places."

The fort was a military system in the border areas of the Song Dynasty. The prefectures and counties governed the villages and the forts under the villages, and together formed a defense system. The villages were not only larger than the fort, but also had more troops and horses. More importantly, they had the storage of food and grass and military materials, which could be held for a long time. With the village as the center, forts would generally be built in important areas around them, relying on each other to achieve control over the vast area. When attacking, the forts could constantly delay the enemy, and also give the villages early warnings, leaving time for war preparations. In peacetime, major traffic routes could be controlled and smuggled.

Thirty miles happened to be a day. After the construction of Pietou Village, it was natural to build a fort here.

Gao's familynu looked at the newly built castle in front of him and his face turned gloomy. Unexpectedly, the Song army rebuilt Bitobu Village, but it stretched forward and even controlled it. Although he was not familiar with the geography of this area, he also knew that the fort was not built casually, but should be part of a defensive system.

This small castle is just at the intersection of the northern Grassland Avenue, located at the entrance of the mountain ridge. The mountain ridge extends to the southeast, and follows the trend, it reaches the entrance of Chenjiagu, connecting Yanmen Pass. The area around Chenjiagukou is Tianchi, and another grassland enters Bingzhou intersection.

Yelu Buhua urged him to come forward, and saw Gao's slave look ugly, and said with a smile: "Sixth brother's face is unhappy, why are he upset?"

Gao Jianu said, "This fort is built abruptly and is about to go north to the Great Road. If it is occupied by the Song people, it will be unfavorable for this dynasty."

Yelu Buhua said: "Sixth brother, the guide has just made it clear that this place is only 30 miles away from Bitouzhai. How could the Song army not build a fort here in one day? If they don't build these, what's the use of them to rebuild Bitouzhai? I heard that the two dynasties in the north and south divide the land according to the watershed. Isn't this place not far from the watershed? Look, the water flows into the Yellow River and the water flows into the Sanggan River on the other side, and the Song army is still in a proper way."

Gao Jianu shook his head: "It's good to follow the watershed, but we have to see which river and which ridge."

Yelu Buhua said: "Are there two rivers here? Of course, one is the Yellow River and the other is the Sanggan River."

After a long time, the Gao family nodded and said in a deep voice: "Yes, Dahegong is really these two. Alas, this fortress is just a way to block the northward road. The Song people occupied this place. If there is any war, they can go straight to Fengzhou, which is a little trouble."

Yelu Buhua said indifferently: "The southerners are cowardly, just to guard against their own dying south. Do you still dare to send troops to attack Fengzhou? The Datong Prefecture and Shuozhou behind them are just dead places. Within 30 miles of Bietou Village, it is said that it is the territory of the Song people, so we don't have to worry about it."

After the Chanzhou Alliance, although the Song Dynasty and Khitan did not divide the borders in this area in detail, the main principle was that they both agreed to use the watershed as the boundary. The water system of the North China Plain was nothing more than the Yellow River and the Haihe River. The watershed between the two was exactly here, and the Great Wall of all dynasties was also built here.

Shortly after Du Zhongxiao rebuilt Biedouzhai, he spent a lot of effort to build a fort here, not aimlessly. One is that he occupied the intersection to go north, and when he had the opportunity, he could go north from here to enter the grassland. The other is that Ningbian Prefecture was abolished.

The Khitans' Ningbian Prefecture relied on this place to contact Shuozhou. After being captured by the foreign tribes, Ningbian Prefecture was abandoned and Du Zhongxiao occupied it, which could prevent the Khitans from rebuilding and avoid future troubles. The rebuilt Biedou Village is just a village. The extended small castles are the greatest value to control the surrounding important places.
