Li Mengxi did not personally lead the team to participate in any siege battles, and learned everything from scratch.

With twelve minutes of investment, Li Mengxi thought of the weak points of most cities - the corners of the city walls through observation.

Combined with what Li Mengxi had thought before, the siege should avoid the stairs as much as possible.

Then, there are targeted siege tactics, which can avoid the staircase entrance of the city wall and at the same time put elite forces in two corners to attack.

Similarly, targeted city defense tactics are also available.

The city wall must always ensure smooth movement of people, so that in times of crisis, people who come up from the stairs for reinforcements can quickly reach the point of danger. Secondly, the corners of the city wall must be specially strengthened for defense.

There are at least two ways to strengthen the defense of the city wall corners.

First, the number of troops that the city wall can carry is limited. Since there is no way to increase the number of troops, it is better to improve the quality of the troops and send more elite soldiers and heavy crossbowmen to guard the corners.

The second is to use manpower deployment to give priority to the supply of crossbows to the crossbowmen at the corner of the city. The frequency of personnel rotation should also be more frequent to ensure that the soldiers in the corner of the city are all fresh troops with sufficient physical strength to occupy the position in close combat.

Advantage, the enemy will not be able to board the city.

From this, Li Mengxi thought of more questions.

That is, how long can an elite soldier maintain his physical strength in fighting? How often should the soldiers guarding the city be rotated? Li Mengxi didn't know.

This is no longer an answer that can be obtained by simple observation. It requires the collection of a large amount of data.

Data related to soldiers' physical strength is extremely important, not only for defending the city, but also useful for field battles.

If the commander clearly knows how long the soldiers will fight before their physical strength can no longer hold up, he can then make a plan in advance, either by substituting someone to take over, or he can predict when a rout will occur and take precautions in advance.

An important basic data was ignored by Li Mengxi.

The last data was that Li Mengxi did not know how long the soldiers marched in one day. Fortunately, he later learned from Guan Yu that it was about fifty miles for ordinary marches. Forced marches were unknown.

Fortunately, Li Mengxi is now aware of the problem.

After all, in hand-to-hand combat with cold weapons, how long does it take for a soldier to go from full combat effectiveness to serious physical exhaustion?

Professional boxing matches in previous lives lasted three minutes.

When I was in the Hanfu community, I heard from the big guys that the physical exertion of full-armor fighting is no less than that of boxing.

So, do we need to change the number of people defending the city in three minutes?

It's unscientific. It can't be operated so fast.

The only thing that can be operated is the rotation of people on the city wall in a small area.

Anyway, there is only a small area for siege ladders to attack the city. The defenders block the place where the enemy's siege ladders are built, and there are only a few people blocking the front to fight.

Therefore, after a while, the people who are pressing on the front are withdrawn to the back, and the people behind are pressing on the front again. After a while, another group is replaced, and the rest is rotated, so that the problem of the soldiers' lack of physical strength is eliminated.

However, soldiers can consciously rotate, which is an ideal situation.

But the actual situation is that if there is not a well-disciplined army, there will be a mixed bag of good and bad among the grassroots commanders. There are those who can take the lead, those who refuse to retreat even if they are exhausted, and there are also bastards who hide behind and urge their soldiers to die.

If it's the former, leading the charge and not going back to rest when you're tired, that's not good. You'll be slow to react due to lack of physical strength, and you'll be chopped down by the enemy troops who are on the city.

And if it's the latter, if you don't step forward yourself and let your subordinates keep pushing forward, it's even worse. The bastard commanders at the grassroots level bully their subordinates on weekdays, and the defenders also bully their subordinates. When people are nervous, their emotions will be unstable.

The slightest contradiction may suddenly intensify. If the soldiers at the bottom become angry and get angry with the bastard officials, the city will collapse in the event of civil unrest.

Internal strife breaks out at the top of the city, and no matter how strong the city is, it cannot be defended.

And this situation has a probability of happening.

We should not rely too much on the personal qualities of the grassroots commanders, but should strictly follow the rules and stipulate that when defending the city, personnel must be rotated on time. Violators should be dealt with according to military law.

In this case, a good man who can lead soldiers will not be chopped down by the enemy because he is too tired; while a bad man who likes to bully soldiers and is inactive will be strictly restricted by military law and will definitely not dare to violate military law.

Human nature is evil, so Han Feizi said, "A husband with a strict family has no ruthless prisoners, but a loving mother has a prodigal son." There are no low-level officers who do not bully their subordinates. There are only officers who dare not bully their subordinates under strict military laws.

Military discipline and orders should treat everyone as a bad person.

Li Mengxi was so lost in thought that he forgot everything around him.

"Xi'er, Xi'er!"

Li Mengxi vaguely heard someone calling him. Then Li Mengxi came back to his senses and made a strange discovery, eh? What's going on in this city? Why is it moving so fast?

Then Li Mengxi turned his head blankly and realized that it was not Cheng Huang who was shaking, but himself.

Liu Bei shook Li Mengxi's shoulders with a look of anxiety.

This section of the city wall was crowded with people.

"What's wrong?" Li Mengxi asked doubtfully.

What happened? Suddenly, a group of people came over without making any sound.

Li Mengxi finally came to his senses, and the frightened Liu Bei finally took a breath. The frightened Liu Bei pressed Li Mengxi's shoulders and could not say a word.

The one who noticed something was wrong with Li Mengxi was the archer who went back to get the crossbow. The archer came to Li Mengxi with the crossbow and the man, saying that he had brought the crossbow.

After saying it several times, Li Mengxi stood there like a wooden block with no response at all. The archer tried shouting a few more times, but Li Mengxi still didn't respond.

The archer felt something was wrong at this time, so he turned to Li Mengxi and saw that Li Mengxi's eyes were empty, as if his eyes could not move and had lost focus.

The archer boldly waved his hand in front of Li Mengxi. Li Mengxi didn't move his eyes. He let his bow reach out to shake Li Mengxi.

At this time, the archer realized something was wrong.

Archer, who grew up in the countryside, recalled what happened when he was a child. When he was a child, there was a child in the village who suddenly couldn't move or move his eyes. People said he was possessed by an evil spirit. Within two days, he was gone.

When he thought of the terrible consequences, the archer panicked and hurriedly called Liu Xuande.

Liu Xuande put down his training and hurried over. He alarmed the whole city again. Then in full view of the public, Liu Bei no matter how he shouted or shook him, he shook his head for a long time. Li Mengxi was shaken so hard that he didn't react at all.

, as if he has lost his soul.

When Li Mengxi finally came to his senses.

"Come on, Xi'er, we won't practice anymore! You're probably tired, so take a good rest!"

Liu Bei couldn't help but pull Li Mengxi directly to the city. He thought that Li Mengxi was too exhausted because of hard training.

Li Mengxi was still confused, so he was pulled away by Liu Bei.

Li Mengxi struggled to break free several times before he succeeded.

"Mr. Xuande? Why are you dragging me?" Li Mengxi's wrist was so painful that he broke free.

Liu Bei didn't say how, he just said he wouldn't practice anymore.

Why don't you practice anymore? Li Mengxi is even more confused.

The misunderstanding was resolved until Liu Bei almost took Li Mengxi back to the camp and walked half a mile.

Li Mengxi laughed when he heard Liu Bei say that he seemed to have lost his soul and couldn't wake up no matter how he screamed.

It turns out that I can be so involved in thinking about things by myself.

There were scientists who were so obsessed with problems that they boiled their own pocket watches like eggs. There were also scientists who were so fascinated by solving problems on someone else's carriage that when the carriage left, they followed the carriage and calculated as they ran.

Li Mengxi pays his own way, am I going to become a scientist? Scientists are extremely dedicated and devoted, and can even build an atomic bomb. Can the difficulty of military strategy be compared with that of an atomic bomb?

Li Mengxi was very happy. He knew that he could devote himself to some thinking. Based on this, Li Mengxi believed that he would be able to learn the art of war well.

Perhaps, it can leave a mark on troubled times and even history.

Maybe he can become a strategist.

Li Mengxi thought to himself.

Liu Bei was too nervous. Li Mengxi was moved and had to comfort Liu Bei.

“Mr.

Don't worry, it's fine."

Li Mengxi said with a smile.

Then, as if to enhance the persuasiveness of his words, Li Mengxi elaborated on the tactics he thought of to defend the city.

"First, when attacking a city, you should avoid the steps of the enemy's city. If you attack the city here, the enemy will be able to rescue them quickly.

Secondly, the city has four long walls, four gates, and watchtowers. I would like to ask Mr. Xuande, where do you think we can attack the city?

I think the four corners of the city wall will help break the city. Please listen to someone."

Li Mengxi carefully informed Liu Bei of the idea he had thought about for a long time.
