It has been more than half a month since Liu Yu led the army into Macheng.

Located on the south bank of the water, Macheng is the northwest gateway to and from Youzhou. The Xianbei people have passed through here to invade Youzhou in the south, the reason is that Macheng is located in a key place, not only the grain and grass are abundant, but also the local wealthy manor is huge, once the Xianbei people get supplies from here, they can drive all the way to the north bank of the Yellow River.

In the past half a month, Liu Yu's mood has gradually changed from the initial worry and anxiety to calm and determined, and now, he has actually begun to tour on both sides of the river, and by the way, he also visited the patriarchs of several large dock forts nearby.

The reason why Liu Yu is so relieved is that he found that he had raised a good son who was relatively powerful.

After Liu He returned to Jicheng, he would send a messenger every two days to report to Liu Yu, who was more than 300 miles away, and the horse could be delivered in two and a half days. Although a large number of messengers were used, it took only five days to make a round trip between the two places, so only five messenger teams were needed to meet the needs of sending letters.

Zhao should do this, not only as a subordinate, but also to allow Liu Yu to grasp the situation in the rear in a timely manner, so as to make a sound decision. The manpower and horsepower that Zhao should use is nothing compared to the nearly 30,000 troops stationed in Macheng, but what it brings to Liu Yu is a more important force than the 30,000 army, which is called confidence!

From Zhao Gai's letter, Liu Yu learned that his son did not rush to "seize power" after arriving in Jicheng, nor did he indiscriminately instruct and give orders, but quickly got closer to his family and officials in the city, and then completely eliminated the source of instability hidden in the city by decisive means. For his son's way of doing things without impatience and hiding needles, Liu Yu felt very pleased and agreed.

Knowing that his son quickly stabilized the situation in Jicheng, he began to raise weapons, grain and grass, and military funds in an orderly manner, and the first batch of grain and grass baggage had already been on the road, and the second batch was also being raised in an orderly manner, Liu Yu's heart felt much more steady.

As long as the grain and grass and military funds are sufficient, Liu Yu has a way to keep the military spirit in front of him stable, as for the attack of the Xianbei people, Liu Yu is ready to rely on the city and several nearby dock forts to defend, although the cavalry of the Xianbei people is powerful, but it is not a copper head and iron arm, in the face of a well-defended city and a strong dock fort, the same will hit the head and bleed, knock out the teeth.

What surprised Liu Yu the most was that his son, who was originally weak and introverted, somehow developed a strong interest in military affairs, and even made a "battlefield autumn soldier" in addition to his busy schedule, which not only greatly boosted the morale of the defenders, but also appeased the big clans and people in the city, and knocked on a loud "bamboo bar" from these big households.

Now, I heard that my son is going to post "Recruitment Notices" in various places to collect and recruit talents, and these things are one after another, and even a veteran of governance like Liu Yu is a little dazzled.

Sometimes, Liu Yu can't help but want to see his son who has not seen him for several years soon, and ask him in person what kind of hardships and hardships he has experienced in Luoyang and Chang'an over the years, so that he can grow to such a level today.

However, Liu Yu is also not very satisfied with some things that his son has done, but this is not the time to investigate and reprimand, everything has to wait until the Xianbei people are driven back to the north.

On this day, the scattered Tanma returned to report to Liu Yu, saying that it was found that the vanguard of the small Xianbei led by Kebineng had arrived at Danhan Mountain.

Danhan Mountain is located one hundred and thirty miles northwest of Macheng, and this mountain range was called Daqing Mountain in later generations. During the period of Emperor Huan, Tan Shihuai, the leader of the Xianbei Tribal Alliance, set up the royal court in the upper reaches of the Qiushui at the foot of Danhan Mountain, and along the Qiushui all the way down to the southeast, you will come to the gateway of Youzhou - Macheng.

Tanshi Huai was brave and resourceful when he was young, and was jointly elected as the big leader by the Xianbei tribes. During his decades of rule in the north, he boldly used the Han people to consult, formulated laws, and forged weapons and tools, which greatly promoted the development of Xianbei society.

In the life of Tanshi Huai, he once led the Xianbei tribes to the south to raid the border counties of the Han Dynasty, resisted Ding Ling (nomads in the Baikal area) in the north, repelled the westward advance of the Fuyu people in the east, and attacked the Wusun Kingdom in the west, not only completely occupying the territory of the Xiongnu who once crisscrossed the desert in the north, but also further expanded the territory to more than 14,000 li from east to west and more than 7,000 li from north to south.

Now, Tanshi Huai has been dead for more than ten years, because he has not yet established a unified Xianbei state power when he was alive, so when he died, the Xianbei alliance quickly collapsed, and split into many branches that did not belong to each other.

Among them, the eastern Xianbei controls the area from the east of Youbeiping to Liaodong, bordering Fuyu and Haoqian, with a total of more than 20 large and small yi, and its leaders are called Mijia, Que Ji, Suli and Mohuai; The central Xianbei is from the west of the right Beiping to the upper valley, there are more than ten yi, and its leaders are Ke Shi, Que Ju, Murong, etc., and are called the big handsome. The western Xianbei from the west of the upper valley to Dunhuang, the west of Wusun, about more than 20 yi, its leaders have the place of Luoluo, Tuoba Lin, Tuoba Tuiyin, Yan Liyang, etc., all are handsome.

This time, the Xianbei leader who led the army to attack and plunder Youzhou was named Kebineng, a young chief who had recently emerged in the Xianbei tribe in central China, he fought bravely, enforced the law fairly, and was not greedy for money, so he was very prestigious among the Xianbei tribes near the border fortress, and everyone jointly elected him as an adult and led the tribe to develop and grow.

The so-called adults of the Xianbei people, also known as the big marshal, belong to the common leaders of several tribal alliances, which are larger than the chiefs of one tribe and smaller than the entire Xianbei chieftain, and their power and status are equivalent to the Taishou of a county on the Han side.

Kebineng admired the great achievements of Tanshi Huai in the past, and he had a huge idea in his heart, that is, one day he would unify the northern desert again, and also establish a country like the Han Dynasty. He often sent spies and meticulous workers to disguise themselves as traders and go deep into the territory of the Han people to spy on the news, so he was very clear about the current collapse of the Han Dynasty and the chaos of warlords in various places.

This time he led the crowd to invade Youzhou, and it was a decision made by Kebi Neng after careful consideration. Since Liu Yu entered Youzhou, he actively promoted the ethnic policy of Huairou and peace, and encouraged the people in the border areas to trade with the nearby Wuhuan and Xianbei people, so that Youzhou maintained a stable and peaceful situation, and got full recuperation.

Youzhou is now like a fattened pig, as long as he breaks in and makes a handful of it, Kebineng is sure that his tribe will grow rapidly, and then fight east and west, expanding the territory several times.

Although Kebineng's ambition is great, he also knows the truth that Lu Dao rice should be eaten one bite at a time, so this time the troops are also very cautious and careful, first sent two thousand tribal elites as the vanguard, stationed in Danhan Mountain, to test Liu Yu's reaction, and then decide on follow-up actions.

If Liu Yu was jealous and fearful, and was willing to make peace, Kebineng would ask Liu Yu for a sum of food and salt and iron supplies with his mouth open; If Liu Yu refuses to negotiate peace, Kebineng doesn't mind fighting Liu Yu fiercely, and then rushes into Youzhou to grab as much as he can.

Of course, Kebineng did not have the absolute certainty and confidence to win this trip, and the most fearful of him was Yan Rou's strength in the area of Baishan in the north of Shanggu County. Ke Bi can know that Yan Rou has a lot of prestige among Wuhuan and the Xianbei tribe in the east, and he can mobilize even more soldiers and horses than himself, if he jumps out to support Liu Yu, he will definitely not be able to get any bargain.

Kebineng had already thought about it, in case Youzhou's precautions were too strict, and Yan Rou really got involved, he immediately turned his head to the west and led the tribe to enter the territory of Bingzhou to plunder. Although Bingzhou has now been spoiled by the Xianbei tribes in central China, no matter how thin the cattle and sheep are, they can always peel off a few pieces of meat. Anyway, the Han people are like ants, no matter how they die, they will not die, as long as there is land to cultivate, they are always willing to live a good life.

However, something surprising happened to Kobineng. Just a few days ago, Yan Rou suddenly sent someone to meet Kebineng, claiming that he was willing to deal with Liu Yu with him, on the condition that after Liu Yu was driven back to Jixian County, Kebi could enter Daijun, and Shanggu would belong to Yan Rou.

Kebineng agreed to Yan Rou's request at that time, in his opinion, as long as the army captures Macheng, Gaoliu and Ningcheng, Youzhou is like a woman who has been stripped naked, and her own people can be as vertical and horizontal as they want, and at that time, you can enter Jizhou all the way south from Daijun, it is said that Jizhou Han Fu is weaker than Liu Yu, and it is just right to plunder.

Regarding Kebineng's collusion with Yan Rou, Liu Yu did not know at this time. Before he entered Macheng, he received the news that Kebineng had united nearly 50,000 people in the central Xianbei to go south, and recently after careful investigation, Kebineng actually only brought nearly 20,000 people to the south this time, which was not as exaggerated as rumored.

Twenty thousand and fifty thousand, these are two very different numbers.

Liu Yu's troops stationed in Macheng were 27,000 people, and they were known as 30,000 to the outside world, and if they defended against the invasion of 50,000 Xianbei people, the troops would obviously fall behind. In particular, there is a long border of more than 400 miles from Ningxian to Banshi, and the Xianbei people can choose one of them at any time and easily break through the defenders' defense line when they have an advantage in numbers.

Now, Liu Yu has figured out the specific strength of Kebineng, and he used nearly 30,000 troops to deal with Kebineng's nearly 20,000 troops, and the pressure has suddenly been reduced a lot. Liu Yu had already sent Wei You to lead 10,000 troops to Gaoliu City, and the order he gave Wei You was to stand by and wait for reinforcements, once Kebineng led the army to attack from Gaoliu, Liu Yu would lead the army from Macheng and go around behind Kebineng to launch a fierce attack.

Liu Yu's strategy is still feasible, but the premise is that Yan Rou, who is eighty miles away from Macheng, will not move, if Yan Rou leads his troops north to Baishan to hide at the critical moment, then the door will be opened in this area of Ning County, and when Kebi can see this vacancy to get in, it will be a big trouble!
