Yang Xi advanced westward, but Cao Cao had already started a war.

Cao Cao also entered the outside for the first time, to be honest, in the face of this endless terrain, he really didn't know how to transport troops.

The ambush is difficult, the strength is supreme, and most of them are infantry troops, and the speed of action is not fast, fortunately, Budugen led 50,000 cavalry to help the battle, otherwise Cao Cao was really a little stage frightened.

Through the battle with Badun, Cao Cao finally realized the wonderful use of the flying ball, which is simply a battlefield artifact, no need to analyze and guess, just release the flying ball, and control the manual quiet.

In the first formation, Kebineng cavalry 100,000 attacked, Cao Cao and Budugen intercepted left and right, the two sides sent troops to test, but Kebineng asked to make a detour to Cao's camp, ready to attack back and forth.

As a result, Cao Cao had already received the news from the Flying Sphere, and divided his troops to intercept Badun and break the Kebineng strategy.

After the first battle, Cao Cao sighed: "This flying ball is comparable to 100,000 male soldiers!" But I didn't think that Yang Xi would be willing to take out such a divine object to help me attack Xianbei, I don't know what he thinks. Could it be that he is not afraid that after I pacified Wuhuan and Xianbei, his strength surpassed him? ”

Guo Jia said: "Yang Xi's thoughts, but he doesn't seem to be in the Han Dynasty, looking at his deployment, he is putting his mind overseas." On this expedition to Xianbei, it is said that he had another 100,000 soldiers and horses to go to the South China Sea to conquer the overseas islands. This person Jia was a little incomprehensible. ”

"I can't understand the person, but I can see it. The reality is that his soldiers and horses are transferred overseas, leaving behind the strength is not strong, and overseas enemies, his soldiers and horses will not be easily transferred back, as long as he defeats Xianbei and gets his soldiers and horses, then my strength will surpass him. ”

Cao Cao is cheering himself up.

In the next few days, Cao Cao did not fight easily, and Kebineng did not dare to attack the camp casually, and the two armies only met sporadically, and the losses were not large.

Cao Cao was waiting for news from Jiang Gan and Yang Xi.

When the news of Jiang Gan came, Cao Cao was greatly excited, and Yang Xi actually spent money to hire soldiers and horses to fight, but this local tyrant's practice made Cao Cao cry and laugh.

Kebi was shocked when he received the news, and he was busy asking about it.

At this moment, an old man dressed in a long robe walked out from the left and right, with a thin face but deep eyes.

"What is Mr. Li's plan?" Kebi can be more respectful to this old man, this person is obviously Han dress.

It turned out that this old man, surnamed Li Mingru, had excellent characters, and was the Lang Zhongling of the Han Shao Emperor, and when Dong Zhuo was ****, he was ordered by Dong Zhuo to enter the palace and poison the young emperor Liu Wei.

After Dong Zhuo's death, Li Dao invaded Chang'an and took control of the government, and Li Dao recommended Dr. Li Ru as his servant, but was rejected by Emperor Xian of Han. Later, Li Dao was defeated by Cao Cao, and Li Ru was nowhere to be found, but he was far away from the plug and arrived in the Kebineng tent.

Li Ru bowed his hand and said: "Today, Cao Cao, Budugen, Yang Xi, and Liaodong Xianbei, the four are coming, with more than 200,000 soldiers and horses, and they are unstoppable. It is better to return to the royal court and earth city, build a high fortress, and guard the royal court, the other army has come to trek far away, and there is no replenishment, and soon when there is a shortage of food and grass, it will retreat. ”

Kebineng sighed and said: "It has been like this in the past, I will retreat when I come, and I will come out if I retreat, I thought that now my department is strong and can compete with the big man, but I don't want to enter this quagmire as well." Let's just listen to Mr. Li's words and return to the royal court for the time being. ”

Some generals on the left and right were not convinced, and jumped out to fight Cao Cao, but Kebineng stopped them all and was not allowed to fight.

The cavalry retreated, the speed was extremely fast, Cao Cao only slept one night and got up, and someone came early in the morning to report that the other party had retreated.

"Follow closely along the road, even if you chase into Da Xianbei Mountain, you have to defeat Kebineng." Cao Cao was determined to pacify the north this time.

A total of more than 200,000 troops, chasing on the grassland, this kind of grand occasion is also rare, but for the vast grassland, these children are playing on themselves, and they can't even wake up from his sleep, because it is too vast.

Kebineng was originally a small tribesman in Xianbei, because he was brave, fair in law enforcement, and not greedy for money, so everyone elected him as the leader.

This tribe was close to Biansai, and since Yuan Shao occupied Hebei, the Han Dynasty had many fleeing to Kebineng.

Kebi was able to teach them to use weapons, and at the same time, he himself learned a lot of Central Plains culture, which was to lead his subordinates to imitate the Central Plains Dynasty, and when he went out hunting, he also learned that the Han army held high the military flag and used drumming as a password to advance and retreat.

As a result, Kobi can develop rapidly, and in ten years, it has a population of hundreds of thousands.

Since there is the integration of the Han people and the penetration of Han culture, it is natural that some people propose to build a city, and it is Kebineng to establish a royal court city. But the city of this royal court is not the same as the city of Han land.

The whole city was built with earthen walls, and the height was not high, but the horses could not cross it, and in the royal court, except for the king's tent, there was a market and a residential area.

Cao Cao went to the royal court fifty miles, and he was not in a hurry to attack, because his own soldiers and horses did not have an advantage, and he went to attack, which was looking for death. On the second day, Yang Xi's soldiers and horses also arrived at the royal court, and the soldiers and horses of the two sides, divided into four directions, surrounded the royal court.

The contrast between the forces of the two sides is not large, Kebi can have 120,000 soldiers, and then there are 40,000 soldiers and horses. Cao Cao's side of the three parties combined, there are only 220,000, separated by the earthy yellow city wall, and it cannot be crushed.

The two sides were in a position, Cao Cao asked the people to raise the tent to discuss the matter, and the Quartet would meet the royal court in the south of the city for thirty miles, each leading a thousand horsemen, and the banquet was discussed.

In this meeting, Cao Cao was the first to ask Yang Xi's opinion.

"Now my army has surrounded the royal court, but the royal court has a lot of soldiers and horses, and they are all good at fighting, if you rush up, I am afraid that you will need to pay a great price, I don't know if Chenhe has a more secure, labor-saving way, to break this city."

Yang Xi has a way to break through the city, that is, he has been bombarding it with artillery.

But it's not easy to expose at this time, what if Cao Cao's eyes are red and he robs at that time?

Thinking of this, Yang Xi decided, haha.

"The prime minister wants to take Ke Bineng, if it is a hard attack, I am afraid that he will lose a lot of soldiers and horses, because Ke Bineng is not incompetent. It is said that the royal court has sufficient grain and grass, and has been prepared in advance, and it is not ideal to surround it for a long time. It's better to surround him for a few days and then figure out a way. ”

Cao Cao was speechless, isn't this Yang Xi full of scheming, why did he say a lot of nonsense this time, which means that he didn't say anything.

According to the convention, it can only be broken by force.

Guo Jia said: "The lord can't delay any longer at this time, he must attack with all his strength and break through the royal court as soon as possible, otherwise once our army is cut off from food and grass, the soldiers will not be effective, and then we will have to wait for him to fight again." ”

Xun Yu, Cheng Pu and others also thought that they could only attack.

Cao Cao had to ask Yang Xi's opinion, so the two sides were allies at the time, but it was not good to give orders directly.

Yang Xi said: "But just rely on the prime minister to give orders." ”

Cao Cao agreed that at ten o'clock in the morning of the second day, he would begin to storm the royal court, and if he won the battle, the first to break through the city would get seventy percent of the spoils.

Now that Cao Cao has accepted Yang Xi's ideas and begun to reform, naturally the clocks and watches produced by Yang Xi have also entered Cao Cao's territory, and almost one of these people at some levels has one.

However, this mechanical clock has a trouble, it needs to be wound, which is also a difficult thing for Yang Xi to solve at present.
