I have planned to force Huangfu Song to force him to do so a few days ago. As soon as the trench tactic was released, there is no doubt that the calculation will be 10%.

Speaking of which, this trench tactic was not something that Li Mengxi had designed himself with his intelligence.

But experience from later generations.

At the end of the Ming Dynasty, Huang Taiji fought with the Ming army. The Ming army was defending with chariots. Because the Ming army was sharp, Huang Taiji could not capture it for a long time, so he surrounded the Ming army's chariots and artillery arrays, surrounded a circle of deep trenches, and then trapped the Ming army to death.

Because he knew this battle example, he encountered Huangfu Song occupying the camp and defending the rebels. The rebels could not attack first and could not take the initiative to provoke the battle. He could only hope to let Huangfu Song retreat when he was in trouble.

Combining various kinds of things, Li Mengxi thought of various tactics and strategies, and finally combined deterrence strategies and trench tactics in order to achieve the goal of retreating Huangfu Song.

By the bonfire, Li Mengxi took a wooden stick and pulled out the tiles from the fire. The roasted soybeans were cooked and they were taken out for a while. Li Mengxi distributed the soybeans to Xiaoqiao, Liu Bei, Guan Yu, Zhang Fei, each with a smaller one.

There were not many soybeans roasted, and each person got less than ten beans, not enough for a pinch. When Li Mengxi gave the beans to Liu Guanzhang for three days, Guan Yu grinned, wanting to laugh but not.

Li Mengxi is a habit, and he has something to eat and is used to sharing it with everyone.

But in the eyes of Guan and Zhang, Li Mengxi, like a child, saw that he divided the beans and counted them one by one seriously, which looked like a child.

A roasted soybean with burnt hair was stuffed into his mouth. Li Mengxi bit it and it was a little hard. He frowned, (The soaked beans still have to be roasted well.) Li Mengxi thought.

Chewing beans, he pretended to be a melon seed, staring at the orange bonfire, thinking for a while, Li Mengxi said, "Now the plan has been completed, and within two days, Huangfu Song saw that my trench was getting deeper and the slope was getting higher and higher. He would be frightened and he would think about breaking through and running away.

At that time, our army had to leave a corner, and Huangfu Song would have to abandon the village and guard.

But..." After pausing for a moment, Li Mengxi frowned, "It is inevitable that Huangfu Song retreated in a hurry, but if Huangfu Song retreated without leaving, he retreated for several miles and escaped from the encirclement of my car formation, and then he still set up a camp to confront me. What should he do?

This time, Huangfu Song underestimated the enemy, and our army could attack Huangfu Song and surrounded his troops.

But now, Huangfu Song knows that our army is in reality and will no longer underestimate the enemy. It is difficult for our army to take advantage of the flaws of the government army to encircle and deter the army."

After saying something, Liu Bei, Guan and Zhang both looked serious.

After Li Mengxi deduced the situation of the war to two or three days, Li Mengxi pointed out that although the trench tactics will surely scare Huangfu Song away, after that, will Huangfu Song not dare to make trouble with the Zhuozhou army again after leaving, or will he still be full of hostility towards the Zhuozhou army even though he cannot retreat. Still want to take the opportunity to wipe out the Zhuozhou army. What will Huangfu Song happen? I don’t expect that both are possible.

Li Mengxi even felt that Huangfu Song might have been stubbornly stubborn in the Zhuozhou army, and would rather die than destroy the army than fight with the Zhuozhou army.

From Huangfu Song's perspective, the Zhuozhou army was self-respecting with the bandits, and they dared to be enemies with the official army. What if the court had no soldiers, what could it be possible to rebel? It was a plan for the court and the world. If such a big bandit was not eliminated as soon as possible and let them become bigger, the Han Dynasty would be in danger.

In private, Huangfu Song was concerned about his own safety and the safety of tens of thousands of soldiers under his command, and should not try to be a dangerous person. However, if you fight for the death, even if you cannot win, you can fight for both defeats and lose the strength of the Zhuozhou army. Then, there will be various rebels who come to fight against it. Even if the Zhuozhou army is strong, it will be defeated, and the big thief will be eliminated.

Li Mengxi knew very well that such loyal and brave old ministers as Huangfu Song would have to regard the Zhuozhou army as a nail in their eyes and a thorn in their flesh, but there was a trace of opportunity to take advantage of that, Huangfu Song would have to bite it.

Huangfu Song had great justice in the court, and attacked the Zhuozhou army only as a fight against the thief, so there was no psychological burden.

If Huangfu Song retreats after two days, what if he waits?

This question has left everyone silent for a long time.

At the end, Guan Yu spoke first, and Guan Yu said in a deep voice, "It is also possible to deter the enemy. Huangfu Song led his army to retreat, and our army led his troops to look after him, so that he could not see the opportunity to win, so he had to leave."

Li Mengxi frowned when he heard Guan Yu's plan.

What Guan Yu said is simple, but the core of the strategy is to maintain a strong deterrence to the official army, grasp the key points of the official army, so that the official army dare not act rashly.

However, when the official army retreats, it is a dynamic trend. It is not easy for the Zhuozhou army to maintain its encirclement of the official army in mobile warfare.

Moreover, with the enemy-to-me-style situation, the officers and soldiers are still strong, and Huangfu Song is still determined to fight.

To form a siege, it cannot be an ordinary siege. The siege of the ordinary siege is only slightly weak, and Huangfu Song's intention to fight is still very strong. If he wants to avoid the war, the possibility of the Zhuozhou army being able to avoid the war is greatly reduced.

Therefore, it is not just a general siege, but a siege is necessary to force the official army into a desperate situation.

However, in mobile operations, it is not easy to surround the official army. It is not enough to surround it. It is also necessary to be able to deter the key points of the official army marching team. It is not enough to deter the key points of the official army for a while. It is also necessary to maintain deterrence at all times. Every meter must have sufficient deterrence to the official army.

Otherwise, if there is a slight ease, Huangfu Song will pounce on him and seek a decisive battle.

It's hard and almost impossible to complete.

Li Mengxi frowned and thought for a long time. He felt a headache. He looked up and looked at Guan Yu and asked, "General Guan, when the official army moves, it is not like when he sets up camp. The fields are scattered and the troops are vast. How can our army surround him?"

Guan Yu pondered for a moment and said, "Use the formation of geese walking to suppress the left and right."

Li Mengxi's eyes lit up, and the geese formation was not unfamiliar with Li Mengxi. Even though he had never studied it seriously, he had also heard a lot about the name of the geese formation in his previous life.

However, now Li Mengxi has a good idea that the formation seems simple, but in fact it is quite particular.

For example, when the cone formation breaks the formation, there can be swords, shields, soldiers and soldiers colliding left and right, long rafters breaking the formation, ground-walking swords, fires, and cows breaking the formation, etc.

Another example is a square array. The square array can only be formed with only one square array, as well as the configuration of front and back forces, queue arrangements, advances in front and back, etc.

Because he knew the formation was profound and subtle, Li Mengxi, when he heard about the formation of Yancheng, even though he knew its name, he did not dare to speak out completely.

Li Mengxi asked Guan Yu curiously. He looked at Guan Yu, his eyes full of seeking knowledge, "General Guan, what is the geese formation?"

When Li Mengxi asked a question, Guan Yu explained seriously.

When they arrived aside, everyone illuminated the torches and surrounded them.

Guan Yu carved the array diagram on the ground with a short knife, and he stroked the left and right, and the array diagram was completed.

The finger formation diagram, Guan Yu explained, "What is the geese walking formation? What are the geese behaviours? When the geese are empty, one branch on the left and one branch on the right is the word "people"."

"If this formation is used, the left and right wings will come out together to suppress the enemy's wings, which will be a force of siege between left and right, and also a force of deterrence."

Li Mengxi knew that the formation of geese was like a human and eight, which was conducive to the formation of two wings circling and harassing the enemy's flanks.

However, Li Mengxi thought about the advantages and disadvantages of the Yanxing formation. Li Mengxi felt that although the Yanxing formation came out from left and right, when the two wings opened, the middle gate was leaking. Although it was to intimidate the enemy and intimidate the official army, so that the official army would not dare to act rashly, the middle gate of his own side became a flaw. Instead, it made the official army think that there was an opportunity to take advantage of it, which was not beautiful.

Li Mengxi pointed out the problem and pointed out the flaws in the middle of the Yanxing Formation.

Guan Yu looked at it in confusion, "...No, the Yanxing Formation, except for the two wings that change, but when the formation first formed, it was first made into a character of the human character and then two more points.

Let’s look, “Guan Yu pointed to a short horizontal line above the word “Man” on the word “Man”, “but half of this array is a vertical array, and the vertical line is in the middle.

This is where the center front heavy troops are located.”

"With this center front, the Yanxing formation was rigorous and flawless. If the enemy attacked our center front with cavalry, he tried to intercept our cavalry. At this time, if our center front was weak, he would be defeated and cut.

However, the center of the geese formation was long and the troops were strong. If the enemy came, they could resist it."

Li Mengxi suddenly realized that this geese formation was really a serious geese formation, a serious and standard character [people], instead of [eight], the eight characters, the middle is weak and the middle door is wide open. The herringbone formation is actually the thickest in the middle.

The difference between the two strokes is that the herringbone geese can change the formation into a horoscope when it reaches halfway, and the left and right wings are separated and around the side of the enemy formation.

If the formation of the character "Eight" at the beginning, if the enemy's cavalry revolts back, they cannot withstand it. People change from eight to eight, from regular to scatter, easy, eight to eight to people, from scatter to scatter, and difficult to scatter.

In short, Li Mengxi believes that the Yanxing formation is cleverly in the two wings and subtle in the middle, and a vertical long middle formation in the middle makes the Yanxing formation have much stronger resistance.

The question is again, there is a need to resist the enemy's recoil at the gate of the Yanxing Formation. Why not place a small cone formation in the Yanxing Formation?

As soon as this doubt arose, there was no need to ask Guan Yu again, and Li Mengxi understood why he didn't use the cone formation.

Because the Yanxing Formation focuses on the formation of two wings after all. If a cone formation is added in the middle, Li Mengxi knows the details of the cone formation. If it is a cone formation, then when the cavalry of the middle cone formation is transferred to both sides, the support will not be fast enough when the cavalry of the middle cone formation is distributed to both sides.

The advantages and disadvantages of the cone formation in the square formation and the long snake vertical formation are that the efficiency of the cone formation's military force is greater than that of the long snake vertical formation and is weaker than the square formation; in the concentration of the troops, the cone formation's military force is not as concentrated as the long snake vertical formation, but the concentration of the square formation.

In short, the cone formation has the length of two formations and the shortest of two formations. It concentrates the speed of troops and the accuracy of troops, so it is the best formation to break the formation.

Yu Yanxing Formation, after all, the Yanxing Formation focuses on the flanks, and the middle forces must be divided into two wings after changing the formation. In this way, the troops in the middle of the Yanxing Formation are the first priority to quickly deploy to both sides, and attack and killing are the second priority.

The long formation in the middle of the Yanxing Formation is like a long snake formation or a square formation. This formation is heavy, long, light, wide, and very good at resisting the perforation of the enemy's cavalry. At the same time, when supporting the two wings, the division of troops is quickly and smooth.

The same force is formed into a cone formation, and the depth is not enough. After the cone formation is divided into two wings, the short and wide formation of the cone formation cannot significantly extend the length of the two wings after being connected to the two wings.

For Yanxing Formation, the longer two wings are more advantageous. If the longer two wings, it can intimidate the enemy's flanks and make the impact of raiding and attacking stronger.

This is the case where the cone array is centered.

The long formation with the character "One" is located in the middle, and the depth of the character "One" is far longer than the cone array, and it is not easy to be drilled through. Moreover, as part of the Yanxing array, as long as the character "One" in the middle is slightly confronted with the enemy, the cavalry on both wings will come over and immediately encircle the enemy.

The cone formation is good at attacking, but its depth is not good at resisting impact.

In the Yanxing Formation, the Yanxing Formation is obviously longer than the surrounding and surrounding formation. Therefore, the most important thing for the center as a connection point is not the attack ability, but the resilience to resist attack. The longer the center forward resists, the more the two wings can surround it.

Here, it is placed in the geese formation. From a holly perspective, the cone formation is not suitable for being placed in the middle.

The same force is used to mount a vertical long formation, which is more solid than a cone formation.

When the formation is changed, the one-character long array is divided into two wings, and the forces are divided into different waters, and the two sides are naturally divided equally, unlike the cone array, the queue is complex and the number of people in each row is different. When it is divided into two sides, the complexity is high and it is easier to be confused.

After changing the formation, the formation of the Yanxing Formation's character "Man" has changed to the character "Eight". After the two wings of the eight characters are connected to the long formation of two points, the length is longer. Therefore, when circling to the enemy's flank, there will be more deterrent area, and in terms of probability, it can also capture the enemy's formation flaws.

If the enemy's flank is a large horizontal formation, if there are ten flaws from beginning to end, our cavalry can attack one of its flaws, then there is a possibility of breaking the formation.

Assume that.

If our cavalry can intimidate the entire horizontal formation, then our cavalry can hit ten flaws in the enemy. Finally, the probability of breaking the formation is 1-0.9 to the tenth power, which is about 70%.

If our cavalry can only intimidate half of the enemy's platoon, then at most it can only hit five flaws in the enemy's army. Finally, the probability of breaking the formation is 1-0.9 to the fifth power, so it is possible to break the formation, less than half a percentage.

If the troops are concentrated, it is also possible to use a cone formation to break the flanks.

Using a cone formation will not intimidate the entire enemy formation, and you cannot use all the fighter jets.

Moreover, the geese formation first grows its horizontal ranks to deter the enemy's flanks as much as possible. If you see the enemy's flaws and are afraid that the troops will be weak, you can also call the team around you. However, if you have thirty or fifty cavalry, you can form a powerful cavalry team.

When the cavalry rushed to the formation, thirty or fifty people were enough to have powerful ability to break the formation.

If thirty or fifty people cannot break through the enemy formation and the enemy formation is still stable, even if 100 people or 200 people, there is a high probability that they cannot break through the formation.

Thirty or fifty cavalry rushing to the enemy's formation, three or five hundred cavalry need to use a cone formation to have enough chance of winning.

The reason why the Yanxing Formation is good at breaking the flanks is that it can intimidate the entire enemy formation, and it can have many more attack opportunities and catch many more fighter jets.

Therefore, although the geese are long and the troops are not strong enough, when attacking the flanks, the general enemy's defense ability is weak. Although the geese are weak in force, attacking the flanks is just right, and the killing and damage formation is the most effective.

Use a cone formation to attack the flanks, break a corner in an instant, and use a geese to break the flanks, break the enemy's formation in an instant, and then break the entire enemy line in an instant.

When the enemy formation was defeated by the geese side, the cone formation only broke one corner. It is self-evident which one is better or worse.

Li Mengxi roughly understood part of the essence of the Yanxing Formation.

[The Yanxing Formation is a formation that is long-lasting and round-roaming, with its sharpness on both wings and firmness on the center.

The center forward focuses on depth but not attacks. Therefore, when looking at the formation, the ability of Yanxing's two wings to surround and attack is far better than the ability of killing and damage in the middle cone formation...

Also, when changing the formation, the center forward is long and simple, making it easier to divide the troops.

When the two wings separate, the vertical formation will be longer and longer...]
