"Phew!" Li Yan slammed a teacup in front of the case, and the teacup turned into a pile of debris on the ground.

"Cao Yue, you are so shameless, you actually sent someone to sneak into my camp to sneak attack," Li Yan looked furious, yelling at the empty tent, "If you have the ability, you will go out of the city to fight to the death with this general, hide in the city and dare not come out, you will only send people to do this kind of sneaky work, what kind of hero is it?" If you are a man, you will fight with Lao Tzu with real knives and real guns. ”

The day was already dawning, the fire in the camp had basically been extinguished, and the incoming officers and troops were nowhere to be seen, and the army was all in the highest state of combat readiness, ready for a possible attack by the officers and troops. After making these preparations, the loss statistics in the barracks were also handed over to Li Yan.

Seeing the loss of statistics, Li Yan was a little irritable. Under strict guard, he still fell for Cao Yue's move, and Li Yan, who was already resentful of Cao Yue, was of course furious.

He swore again that if he defeated Cao Yue and captured him alive, he would be humiliated before killing him.

However, Li Yan is also an extraordinary person after all, he vented viciously, and after his anger, he also calmed down and carefully analyzed this accident. He had to admit that he still looked down on Cao Yue.

Under such strict vigilance, Cao Yue's men and horses were still able to sneak into his camp and leave calmly after some destruction, while his men and horses, not to mention killing the other party in a panic, did not even see the shadow of the other party, and it was not clear how many officers and soldiers sneaked into the camp to sneak attack, how they infiltrated, and how they left. Originally, Li Yan thought that Jiannu was attacked by Cao Yue several times on the way to the south, which was due to Jiannu's carelessness and Cao Yue's luck, but now he doesn't think so. Under Cao Yue, there must be an elite team of people with super combat effectiveness.

This is a force that cannot be underestimated, and Li Yan deeply understands this.

In this surprise attack of the official army, Li Yan's men and horses were killed and wounded nearly 2,000 people, and of course the greater loss was grain and grass. In Li Yan's army, the grain grassland is already poor, and it can only support about half a month at most. This time, the officers and soldiers destroyed two places where grain and grass were stored, and nearly 30% of the grain and grass were lost.

This was a fatal blow to Li Yan's army, and he had to reconsider the next battle arrangement.

Liu Zongmin's army will not arrive in a few days, and if the official army adopts delayed measures such as raiding and harassing, it may not be able to arrive in ten or so days, and the other troops will not be able to delay these days at all. Li Chen was thinking about whether to start attacking the city before Liu Zongmin's army arrived, and strive to use his 80,000 horses to break through Datong City. Or, just retreat like this and join up with Liu Zongmin's troops to avoid greater losses?

Li Yan did not have any confidence in the breakthrough of Datong City, and he really understood the combat effectiveness of the official army this time. The combat effectiveness of the Datong Army far exceeded his imagination, and it was only higher than that of other troops. In the face of such a team of men and horses with superb combat effectiveness, and still sitting on the fortified city of Datong, it is very unrealistic for him to want to attack it. It is also unrealistic to retreat, if he withdraws before receiving Li Zicheng's order to withdraw his troops, he will definitely be severely punished, Li Chen knows that the most important purpose of his troops attacking Datong is to contain the officials and troops in Datong and Taiyuan, and prevent them from going south to support Henan and Shaanxi.

Li Yan's only choice now is to continue to attack Datong.

Of course, Li Yan has other methods, but he is not sure whether those methods can succeed or not.

Before sending the Red Lady to Datong to inquire about the military situation, Li Yan appointed some other people to bring property to Datong to buy the guards of Datong. If the purchase is successful, when the city is sieged, these buyers can open the city gate and let the rebels enter the city, and it is possible to capture Datong without blood. Before leading the army to Datong, Li Yan also received a report from these people that someone was willing to cooperate with them. It's a pity that it is not the general under Cao Yue who is willing to cooperate, but the general and deputy thousand generals. And Cao Yue arranged a very high level in the guarding of each gate in Datong, and the deputy general and general figures did not necessarily have the opportunity to open the city gate and let the righteous army enter the city.

After thinking about it for a while, Li Yan still decided to be cautious, not to rush to attack the city first, but to pull out the camp and set up the village, and then retreat twenty miles back to find a more favorable terrain to camp, and continue to wait for Liu Zongmin's army to arrive at the same time, send men and horses to the vicinity to collect grain and grass to supplement military supplies.

*************

There is one thing Li Yan did not think wrong, that is, at the same time that his unit was attacked by the elite detachment of the official army, Liu Zongmin's army was also attacked in the same way. It's just that Liu Zongmin's troops, who did not take strict precautions, suffered far more serious losses than other departments.

Although Cao Yue wrote letters to Li Yan and Liu Zongmin respectively, he did not think that his letter would impress the two men, so that they would give up the attack on Datong and join forces with the official army to fight against Jiannu. If the rogues could have done it with a letter, they wouldn't have become more and more violent.

Therefore, Cao Yue did not slack off at all, and while strengthening his vigilance, he ordered the members of the elite special training team under his command to use all methods to delay the march of Liu Zongmin's army and constantly harass his troops along the way.

Cao Yue's feelings about Li Yan and Liu Zongmin are different, Li Yan wants to fight for it, which is the most important reason why he has not done anything to Li Yanbu after he sent a special training team, and he has not killed the red lady.

If Li Yan's men and horses can be won over, the general trend of the world will be reversed immediately, Cao Yue is very sure of this.

As for Liu Zongmin, Cao Yue just wanted to eliminate it, and he had no idea of fighting for it, so he hit Liu Zongmin's department earlier and more ruthlessly.

Within half a month, Liu Zongmin's department was attacked five times inexplicably, there was no sign before, and no clues could be found afterwards, and the methods of each attack were similar, that is, the offenders mainly burned camp tents, grain and grass, and did not love war, and left after they succeeded.

In these few attacks, Liu Zongmin's troops suffered losses were not very large, except for grain and grass, the personnel did not reach the point of breaking their muscles and bones, but the blow to morale was very big, even to the point of a cup, a bow and a snake. As a result, the march of the army was seriously sluggish, and the food and grass were much tighter than planned. In order to avoid a shortage of grain and grass, Liu Zongmin had to order "expropriation" from the people along the way.

Of course, this expropriation is of a semi-coercive or completely coercive nature, and there is not much difference from open robbery.

And Cao Yue, who received these favorable battle reports, was greatly invigorated. Liu Zongmin's army began to plunder the people, and he could have defeated or annihilated them from the standpoint of justice. Li Yan has been ignoring his overtures and continued to advance towards Datong City, and Cao Yue also temporarily gave up the Huairou policy, ready to give Li Yan some warnings, and then see if it is possible to fight.

If Li Yan is still obsessed after hitting Li Yan hard, then he can only kill them all.

Cao Yue began to adjust the layout and plan, preparing to attack, and before the Liukou came to attack the city, he wanted to break Li Yanbu and Liu Zongmin's heads. He believed that he could defeat them, in his eyes, the combat effectiveness of the Liukou could not be compared with Jiannu, in the original history, if there was no Jiannu from time to time, the elite of the Ming Dynasty was exhausted, and there was no chance for Li Zicheng and Zhang Xianzhong to become a climate.

The Ming Dynasty was destroyed by Li Zicheng, not that Li Zicheng's army was very combative, but that the combat effectiveness of the Ming Dynasty was scum.

Although Cao Yue received red education since he was a child, before he became sensible, he also agreed that the peasant uprisings written in history textbooks were all righteous and rose up to overthrow the decadent feudal rule, but when he grew up, he learned more about history and completely changed his perception of history. He gradually accepted the scourge of peasant rebellions, which were deliberately ignored by the government and textbooks, especially Huang Chao in the late Tang Dynasty and Li Zicheng and Zhang Xianzhong in the late Ming Dynasty.

After crossing over to the Ming Dynasty, he vowed to change history with his own ability, to expel foreign captives, pacify the rogues, and restore peace to the world.

Of course, he will never be subservient to anyone, including Emperor Chongzhen, who is now holding a heavy army and has already germinated the idea of relying on his own strength to create a new era. And to achieve this goal, it is necessary to destroy all the enemies to be eliminated and to win all the allies who can be won. Li Yan and the Red Lady couple still want to fight for it, but he has to teach them some lessons now.

"Take the initiative to attack and destroy the prisoners", this is Cao Yue's latest plan.

He took the lead in attacking Li Yan's department.
