Baishan Duwei City, referred to as Baishan City, is located in the north of the Baishan Mountains in the northwest of Youzhou, 100 miles away, 30 miles away from the Weishui River in the east, and was only started to be built in the past two years.

After taking office, Du Yi, the governor of Baishan, was over 30 years old and had outstanding ability, and after taking office, he vigorously promoted the "assimilation" policy set by Liu He, and integrated dozens of tribes that were originally attached to Yan Rou into four large united tribes, each of which had 20 percent Han people, 30 percent Wuhuan people, and 50 percent Xianbei people. These four tribes were named left, right, front and back four by Du Ji, the implementation of semi-military management, each department has a Qu Zheng one, Qu Zuo two, the team of four people, elected by the tribe of each tribe, seven of them two Han people, two Wuhuan people, three Xianbei people.

As the supreme governor of Duwei City, Du Ji grasped the military and political affairs, and had the power to kill and seize the city, but he never abused the power in his hands, and paid attention to convincing people with reason and ruling the city by law. Because Du Ji has clear rewards and punishments, enforces the law fairly, and will not favor the Han people, and the seven core managers of the four departments are from the three tribes, they can effectively supervise each other, so the four integrated united tribes are very supportive of Du Qi, and they can also implement the orders he issued well.

In order to build a strong acropolis for Youzhou on the northern grassland, Du Yi specially set up a cattle and horse transport team, and set up a quarrying team, he asked the quarrying team to dig out the stones used in the construction of the city houses in the white mountain, and then the transport team used ox carts and horse-drawn carts to transport back to the selected city site hundreds of miles away, so he began to build the city with the general stone of Yugong moving mountains.

Later, Liu He learned of Du Ji's grand plan and was very supportive, when there was a great drought in Youzhou, many young and strong laborers had nothing to do, so Liu He mobilized 50,000 laborers from the state to cross Baishan. went to support, and this work took half a year.

Nowadays, the Baishan City made of bluestone has begun to take shape, although it is only more than one zhang high, and there are two city gates in the south and north, but it also makes the soldiers and civilians stationed in the city feel much more at ease, even if they know that the Xianbei people in the east may come to attack, they can still stabilize their minds and prepare for various preparations to meet the enemy.

On this day, Zhao Yun and Du Qi rode horses around the circular city wall and carefully inspected it. Check whether there are gaps and messes in the walls and gates, so that they can be repaired and completed in time.

"The city wall is still a bit short, although it can block the cavalry of the Hu people, but if the Hu people carry well railings and ladders, the terrain advantage of the defenders will no longer exist. I'm afraid that the casualties will be too big by then! Zhao Yun frowned and said with some concern.

"The amount of work to build the city is too large. It will take at least two years. In order to completely build a three-zhang high city wall, it can only be defended with the help of the current scale in a short time. Du Yi said a little unwillingly.

Zhao Yun thought for a moment, and suddenly said: "Now that it is the midwinter weather, can you organize manpower to fill soil with straw bags, pile up two feet on the basis of the existing wall, and then water it day and night from top to bottom." Make it ice solid and become an ice wall, which will greatly enhance the defense of the wall. ”

Du Ji listened to Zhao Yun's suggestion and thought about it for a while. He showed a look of surprise and said excitedly: "This plan is absolutely feasible!" If there is no stone wall more than one zhang below as a foundation, pouring the ice city on flat ground is easy to collapse because the foundation is not strong, and the Hu people can also set fire to roast when they come, so it cannot be implemented. Now, if the existing stone wall is more than one zhang high, the soil is watered, and there are no such problems, and it can play a temporary protective effect until the ice melts in April next year. ”

"With these few months, it should be enough. Then organize the labor force in the city to start work immediately! Zhao Yun made a decision and made a decision.

Over the next few days, more than 10,000 people in the city toiled day and night, digging pits not far from the city to extract soil, and then filling the soil into straw bags to make dozens of pounds of soil, and then transported by the soldiers to the city wall, neatly stacked layer by layer. The people in the city set up large iron pots and copper pots to melt ice and draw water, and then carried them to the top of the city wall and poured them into the straw bags one by one, until the warm water formed a thick layer of ice in the cold wind and covered the outside of the earthen bags.

There are four united tribes in the city, just one tribe is in charge of a city wall, under the major threat of a strong enemy, no one complains about being tired, and no one asks Du Ji for wages, everyone only knows that the higher the ice city is poured before the arrival of the Xianbei people in the east, the safer everyone will be at that time.

Time passed in a flash in the hard work of the soldiers and civilians of Baishan City, and soon ten days passed......

On the towering bucket in the middle of the city, a young Wuhuan soldier was wrapped tightly in his body, leaving only a pair of piercing eyes to look to the east and north.

Suddenly, his pupils contracted inward, and a nervous look appeared in his eyes.

"When...... While! The hurried alarm bell rang by him.

Xianbei people are coming!

When Zhao Yun heard the news, he calmly climbed the corner tower on the east side, holding a clairvoyant mirror to carefully observe the sentry cavalry and leading troops of the Xianbei people that appeared faintly in the distance.

"Immediately send a messenger to leave from the west gate, and report to Macheng, saying that the Xianbei people in the east have arrived, with more than 20,000 troops, and the Baishan Governor's Mansion is confident that the enemy will be outside!" Zhao Yun gave an order to the herald behind him.

The Xianbei people have always sent troops, large and small tribes gathered together, and then commanded by jointly elected leaders, they are not as neat and strict as when the Han army went out on the expedition, so the time to arrive at the combat area is often inconsistent, and it always takes two or three days to gather.

The Xianbei people were so scattered, but they were not afraid that the Han army would go out of the city to attack the troops that arrived in advance, because what they were best at was guerrilla warfare. If the Han army goes out of the city, the troops who arrived in advance will move closer to the troops coming from the rear, and if they encounter the kind of Han generals who don't know the depth, they only know how to command the troops to blindly pursue, and the final result is likely to be surrounded by the Xianbei people, resulting in the annihilation of the whole army.

The biggest advantage of the Han people is that they carry out organized defensive operations with the help of cities and other covers, and gallop across the vast grassland, which is the innate ability of Xianbei warriors.

When the Xianbei people outside the city began to gather more and more, the Han army in the city really did not move quietly, which was no different from before.

The Xianbei leader who came first, Cheng Lugui, is the nephew of Su Li, the largest leader of Xianbei in the east. Su Li was only a little younger than Tanshi Huai, and it was he who led more than 700,000 Xianbei people in the east to support Tanshi Huai and unite the eastern, northern and western Xianbei people to fight against the Han Dynasty. After the death of Tanshi Huai, the Xianbei Great Alliance collapsed, and Su Li became the boss in the vast northeast grassland west of the Great Xianbei Mountain (the Great Xing'an Mountains of the later generations) and north of the Yan Mountain.

Su Li already felt that he was getting old, and at the same time, he felt more and more that the eldest prince who suddenly appeared in Youzhou in recent years was really the number one public enemy of the Xianbei people, so he agreed to Kebineng's proposal and sent his nephew and the warrior Micah in the tribe to lead the army to the west, to respond to Kebineng's actions, and also to train the successor of the next generation.

Cheng Lugui squinted his eyes and stared at the towering city not far away for a long time, his face getting darker and darker.

"Douling, you idiot, open your eyes bigger than a horse, and take a good look at how high this city is in front of you!" Cheng Lugui tightly tugged on the chest of a strong man in his thirties with both hands, and shook it vigorously, causing the other party's face to turn red and his eyes to bulge outward.

Su Douling's heart was bitter for a while, and he stammered a little and explained to Cheng Lugui: "Lord Qi, Lord Qi...... Half a month ago, when I brought people here to investigate, this city was really ...... It's really only more than one zhang ......high, and I don't know what magical tricks the Han people have used, and they have actually increased the city wall by more than two zhang in these few days......"

"Xi Doulu, Qi Jin, what Su Douling said is the truth?!" Cheng Lu asked the other two scout leaders.

"Returning to the lord, the little one is willing to use the head of the item as a guarantee, and what Su Douling said is not half a lie."

"You two go east at once to Micah, who is still on the way, and let him stop and cut down the trees when he comes across a tall and dense place along the way, and then carry them over!"

Cheng Lugui was sober-minded, knowing that the situation in Baishan City this time had exceeded expectations, and if he didn't make adjustments in time, he was afraid that it would affect the entire plan for the Western Expedition.

At the head of the city, Zhao Yun carefully observed the camp layout of the Xianbei people, and then turned his head and asked Tang Meng and Lu Chihu beside him: "When do you think the Xianbei people will attack?" ”

Tang Meng replied: "Within three days at the latest." ”

He replied, "Five days later." ”

Zhao Yun shook his head and smiled indifferently. "I don't think the Xianbei people will attack for half a month, you carefully observe the camp they have laid out, it is completely defense-oriented, which means that they are not ready to attack Baishan City."

"General, since the Xianbei people dare not attack for the time being, their subordinates ask for orders and lead the team out of the city at night to attack the camp of the enemy chieftain!" Tang Meng asked for battle.

"It's okay to attack, but you need to accept it when you see it, and you can't go deep alone!"

"Subordinates take orders!"

In the middle of the night, Tang Meng led a thousand cavalry who were good at night warfare to quietly go out of the city from the north gate, and then touched the north side of the Xianbei people's camp, intending to make a surprise attack, but the Xianbei people were actually prepared, and immediately sent a team of cavalry to meet the battle, which scared Tang Meng out of a cold sweat.

Tang Meng immediately made a decision, immediately turned around and ran with his troops, and ran towards the north for more than thirty miles in one breath, until he threw off the pursuing Xianbei people, and then returned to the city from the west gate in a circle.

In the city, Tang Meng was still angry and grabbed the first attack task, and when he saw Tang Meng returning with the team dejectedly, he asked in a low voice, "What's the matter?" I see that there are many people entering the city, why do you look like a dead mother? ”

"You just died my mother, your whole family is dead!" Tang Meng was angry, and he turned his face with Chihu at that time. (To be continued......)
