In order to explore the details of the enemy city, the sword and shield warriors were dispatched twice, and each time they were damaged.

The first time it went by, it was okay, some of the injuries were minor. The second time, one person was hit by an arrow in the cheek, and it looked like the situation was a bit serious.

Li Mengxi followed him and watched for a while, but because he couldn't be of much help, he left.

Outside the wounded barracks, Guan Yu was waiting there.

When Li Mengxi saw Guan Yu, he said, "We should bring fewer people with us. If we take less people with us, we will suffer less damage."

Li Mengxi meant that there shouldn't be so many people exploring the enemy city.

The more people there are, the more casualties there will be.

Guan Yu was silent for a moment, then looked at Li Mengxi and said, "That's not true." Guan Yu refuted Li Mengxi's statement.

"Xi'er, let me ask you, how many people were injured when you went to explore the city this time?" Guan Yu asked.

"Ten people." Li Mengxi answered directly without thinking.

"Yes." Guan Yu nodded, "Two hundred people came to the city and ten of them were injured. Ke Xi'er, do you know that if we only send ten soldiers to the city this time, all ten of them will die."

"Two hundred soldiers were sent, and ten were injured. Ten soldiers were sent, and all of them died. How can we say that if there are fewer people, there will be less casualties, but if there are more people, there will be more casualties?" Guan Yu looked at Li Mengxi with a smile.

Li Mengxi was immediately confused. He couldn't understand. Isn't it wrong? There are more people and more people will bear the rain of arrows, so there will be more casualties.

With fewer people and fewer targets, there will be fewer casualties, isn't it?

Li Meng was puzzled. He raised his head, looked at Guan Yu doubtfully, and asked, "If there are ten soldiers, how can all ten of them die? How does it make sense?"

That's the truth.

But Li Mengxi asked, is this the truth? Guan Yu pondered for a long time, and after thinking about it for a long time, he thought of explaining it to Li Mengxi.

"So, Xi'er, have you ever read "Lu Shi Chun Qiu"?" Guan Yu asked.

"Never." Li Mengxi was even more puzzled, asking what the casualties had to do with Lu's Spring and Autumn Period.

Guan Yu then said, "There is a saying in "Lu's Spring and Autumn Annals" which says, "Ten thousand people wield bows, and they shoot one move together, and all of them hit the mark."

The implication is that if ten thousand people shoot at the same target, they will definitely hit the target.

When approaching the city, there are many yellow scarves at the top of the city, so let's say he has a hundred archers.

If I approach the city with a hundred men, and he shoots at me with a hundred archers, and one man with one bow, it is hard to predict whether he will hit me or not.

If I approach the city with ten men, and hundreds of archers shoot at me, and ten bows shoot at one person, all of them will miss, and nine-one will be divided equally. If I approach the city with only one man, and hundreds of bows will shoot at me, there will be no chance for that person to survive.

So, maybe you understand?" Guan Yu looked at Li Mengxi with a smile.

Li Mengxi was in shock at this time.

What's shocking is that Lu's Spring and Autumn Annals, as the name sounds, is an ancient work from the Spring and Autumn Period and the Warring States Period. However, such an ancient work magically mentions the knowledge of weapons in it.

The second shocking thing is that the killing effect of crossbows is related to probability, and Guan Yu obviously understands the principle of probability, which can be heard from Guan Yu's expressions.

At the third point, Li Mengxi suddenly understood that our siege force could be large or small. The enemy's force was limited by the city wall, so the total force remained unchanged.

Whether there are more casualties or fewer casualties in an attack with ten men or a hundred men is entirely a matter of probability.

You can do some calculations.

Assume that the enemy's crossbowmen are of equal skill, and when the enemy aims and shoots at one of our soldiers, the probability of him being able to kill or injure our soldiers in the entire battle is assumed to be one in ten.

So, if there are a hundred archers at the top of the city, and I attack the city with a hundred men, and each archer at the top of the city is targeting one of me, then the probability of each of the siegeers being killed or wounded is one-tenth.

Question: After a battle, what is the probability that more than ten people will be killed or injured?

The simple calculation is to multiply ten 0.1s and then multiply them by ninety 0.9s to get the probability.

Then calculate the probability that if ten people attack the city, ten people will be killed or injured.

Comparing the two, it can be clearly concluded that when a hundred people attack a city, the casualties are more likely to be smaller than when ten people attack a city.

From this, Li Mengxi figured out an important issue.

When facing the enemy's crossbow troops, the more people there are, the fewer the average casualties will be, because the enemy's arrow rain can be thinned.

On the contrary, if our team is a crossbow unit and the enemy is the target, then the highest killing mode is to treat hundreds of them as one person, that is, our army will attack the opponent's target as much as possible. Then in one round of attack, the enemy will be

The target is almost guaranteed to die, and then the second target is attacked at the same time.

This is the most efficient tactic, which shows the importance of concentrated fire.

At the same time, a question arises. It is possible for the crossbow team to focus fire on the same target, but how to specify the target?

Li Mengxi immediately thought of a way to use the Ming Dy! Maodun Chanyu used the Ming Dy to guide the attack. This tactic was very suitable for small-scale battles.

When defending the city, for every fifty crossbowmen, one of them is an experienced soldier who can judge the situation on the battlefield. This veteran uses a bow and a hammer with a red rod and a red feather.

Wherever the dynamite was fired, dozens of people nearby would attack, focusing the fire on the enemy troops in the city.

In this way, the killing efficiency is several times that of the respective attacks.

Especially in certain critical moments, when the enemy is about to climb up the siege ladder, repeated shooting by two people at this time is not enough to shoot the enemy off the ladder immediately. Everyone nearby must immediately focus their fire.

How to focus fire, how to coordinate manpower, and how to designate targets, Mingdi is the best choice.

Siege tactics have been updated again.

The tactics of defending the city have also been updated again.

The defenders of the city should arrange for Sergeant Ming Dy, who is good at shooting, to direct the fire target.

This Ming Dynasty scholar may be called a "Sound Shooter".

Guan Yu had been sizing up Li Mengxi, and when he saw Li Mengxi's brows furrowed in thought, then his brows softened slightly as if he had realized something, and finally, Li Mengxi suddenly smiled, Guan Yu knew that Li Mengxi must have understood why there were more people.

When attacking a city, there will be fewer casualties.

"General Guan, I figured it out!" Li Mengxi raised his head and looked at Guan Yu with a proud look on his face.

Guan Yu nodded, looked at Li Mengxi, and said, "When a hundred people attack the city, the casualties will be less than when ten people attack the city. There is another key point - the shield formation.

Xi'er, if you think about it, if ten people form a shield formation, no matter how many people are in front or in front, or how they are arranged, there will be huge gaps. In the rain of arrows, it will be like a single shield.

This chapter is not over yet, please click on the next page to continue reading! But if a hundred people form a shield formation, ten vertically and ten horizontally, the shields overlap each other, they are as dense as tiles, and they are like a roof.

Such a shield array is like a tortoise shell. If the enemy has hundreds of people drawing their bows and shooting at them, how can they hit the gap with one shot? Even if there are hundreds of people who can shoot with magic, it will be difficult.

Therefore, it is difficult for ten people to form a shield formation, but a hundred people can form a tortoise-shell shield formation. Therefore, if a hundred people attack a city, the casualties will be less than if ten people attack the city."

Li Mengxi's eyes widened again.

Li Mengxi was surprised. He looked at Guan Yu in surprise. He really didn't expect this. He didn't expect this at all. There were many people to attack the city, and because of the shield formation, it could effectively defend against arrow rain. But ten people formed a shield formation and formed a hammer.

No matter how the shield formation is set up, there are always flaws. If you focus on the front, you will not be able to take care of the rear. If you focus on the left, you will not be able to take care of the right.

Li Mengxi admired Guan Yu's knowledge in military battles, and Li Mengxi could not have imagined this.

Seeing that Li Mengxi looked like he understood, Guan Yu stroked his beard and said, "The reason why a hundred people came to the city to investigate instead of ten is because besides the casualties, besides the shield formation, there is a third place, which is particularly important."

Guan Yu's tone became solemn, "Xi'er, have you ever thought about it. We went to Lincheng to investigate the details. If only ten soldiers went there, by chance, the Yellow Turbans saw an opportunity and suddenly lowered the drawbridge and opened the city gate.

The cavalry was like the wind, suddenly charging toward us. At this time, we were thirty steps away from the city, and close to the city gate. Our army was still in camp, three hundred steps away.

The cavalry rushed forward in an instant, and there were only ten of us. How could we resist? Even if we tried to escape, we would not be able to escape, and we would all die."

Guan Yu told a terrible fact, and Li Mengxi was even more shocked. He suddenly understood that the Yellow Turbans guarding the city could actually come out! It turned out that the defenders could suddenly attack and harass!

Thinking of this, Li Mengxi suddenly asked anxiously, "If that's the case, then if our army is surrounded by three and one is missing, why don't we resort to death?"

The north and east gates are surrounded, and the south gate is surrounded without a single soldier. If the Yellow Turban Cavalry suddenly rushes out from the south gate, and the two men from the east and west are not far from the south gate, wouldn't our army be attacked by them on the flank in an instant? Especially in the event of an attack on the city.

When he was in full swing, he suddenly attacked and cut off my rhythm of attacking the city. Wouldn't it make all my previous efforts in vain?!" Li Mengxi stared at Guan Yu with wide eyes. In anxiety, he immediately pulled Guan Yu away and asked Guan Yu to hurry up.

After preparing, the provincial ones were killed by the Yellow Turbans from the south gate.

Seeing Li Mengxi like this, Guan Yu laughed loudly, "Don't worry, don't worry!" Guan Yu reassured, "I have already ordered the east and west battalions to be on guard against enemies coming from the north. The Yellow Turban cannot fight with our army in the field. If he dares to come out, it will be just right.

Impairing his military strength." Guan Yu stroked his long beard with his hand, smiling lightly, looking indifferent and extremely determined.

"However," Guan Yu looked at Li Mengxi and commented, "Xi'er, you did not think carefully about the method of encircling three and missing one. If you besiege the city in the future, it is better to leave one gate open. You should give it careful consideration before proceeding.

.”

Li Mengxi nodded solemnly, then looked serious, took a step back, straightened up and bowed towards Guan Yu and saluted seriously, "Thank you, General Guan, for your teaching."

Li Mengxi's gratitude was heartfelt.

Guan Yu stretched out his hand to help Li Mengxi, which was regarded as a courtesy from Li Mengxi.

This time we came to besiege the city, and the strategy of besieging three and missing one was proposed by Li Mengxi.

I didn't expect this strategy to be so stupid.

Guan Yu also knew that it was inappropriate to surround three people without one, but he didn't tell Li Mengxi, but made preparations on his own.

Fortunately, the enemy was the Yellow Turban. If the enemy was someone like Gan Ning, leaving a gate open for Gan Ning to come and go as he pleased. Gan Ning led a hundred cavalry out of the south gate, circled half a circle around the city, and reached the east gate.

A hundred cavalry attacked the camp at night, and our army was in despair!

Surrounding three and missing one is a recipe for death!

If this strategy is used, the timing must be considered.

This timing is the essence of the method of surrounding three and missing one.

So, when is the appropriate time for the three-dimensional and missing one? When is the time when it is not applicable?

Li Mengxi asked Guan Yu, but Guan Yu could not give a detailed answer for a while, so they started discussing on the spot.

There is no doubt that the time is not suitable to surround the three and one missing, but now is not suitable. One door was left open, which gave the Yellow Turbans the convenience of leaving the city for a sneak attack.

Thinking about it, the strategy of surrounding three and missing one should be applied when the enemy is at the end of its rope, rather than surrounding three and missing one from the beginning.

When the enemy's troops in the city are strong and their fighting spirit is high, rigidly using the tactic of surrounding three and missing one is tantamount to self-destruction.
