When Guan Yu saw Li Mengxi talking, he frowned and became silent again.

Guan Yu and Liu Bei didn't want to disturb Li Mengxi who was deep in thought, so they had to wait until he turned around before asking.

At this time, Li Mengxi was fascinated by what he was thinking about.

Among the countless mixed pictures in his mind, Li Mengxi thought of what he had seen on cctv7, the agricultural and military channel. When the special forces fought in the field, when they crossed the cliff between two mountains, they used bows.

The crossbow shoots the iron hook connected with the rope to the other side of the cliff. As long as it hooks the tree trunk, stone or something, as long as the hook is strong, people can climb over along the rope like an ape.

Using a crossbow to throw the rope is much faster than climbing over it manually.

It is not clear which one is more powerful, the crossbow of the 21st century or the most powerful rhubarb crossbow of the Han Dynasty.

At worst, if the strength of the big yellow crossbow is not good, just bring the bed crossbow over and fire the crossbow. With the strength of the bed crossbow, let alone hang it on the opposite tree, the crossbow gun can also penetrate deeply into the cracks of the rocks.

The suspension bridge was broken, and agile soldiers were sent to climb down the cliff. Under extremely difficult road conditions, it might take half an hour to climb to the cliff on the other side.

Moreover, in the process, the soldier may lose his footing and fall off the cliff.

And if you use a strong crossbow to fire an iron hook, or use a bed crossbow to fire a crossbow arrow connected to a rope, you may be lucky. Once the crossbow arrow is fired, the iron hook will hit a crooked-necked tree on the opposite cliff dozens of meters away.

It may take less than a minute.

One minute, compared to one and a half hours, the time saved is twenty-nine minutes.

Twenty-nine minutes, considering that five seconds can be used to release one person along the suspension bridge to the opposite side, the time advantage of twenty-nine minutes is enough to release hundreds of people to the cliff on the opposite side.

Taking advantage of the enemy's surprise, several hundred people were able to circle around from the mountain to the back of the enemy's camp and lay in wait until nightfall, enough to catch the enemy by surprise.

Li Mengxi even knew what the grapple hooks of the special forces were like - the best grapple hook shape should be one grapple hook with three or four curved iron hooks. In this way, no matter what angle the iron hook is shot out from, it will be at least

There is a hook that can be hooked onto the tree trunk.

Not only can it be used to build bridges between cliffs, but also to build pontoon bridges on rivers, you can also use a bed crossbow to shoot the rope across. It is very fast, convenient, and safe.

It seems that the military's technical equipment has to be increased. In addition to ordinary crossbow arrows, the crossbowmen should also be equipped with a grappling hook arrow to facilitate passage on cliffs.

Brilliant! Special arrow. Li Mengxi couldn't help but smile on his face.

Seeing Li Mengxi's brows soften slightly, Guan Yu put a piece of firewood into the bonfire and asked curiously, "Xi'er, why are you so happy?"

Li Mengxi came to his senses and told Liu Bei and Guan Yu excitedly what he had just thought.

"General Guan, Duke Xuande. As we discussed before, every hundred men in the army should be equipped with one or two grappling hooks to facilitate the extraction of the stronghold.

Now when it comes to building a suspension bridge between cliffs, can we make a special crossbow arrow with the arrow shaped like a grappling hook? When the cliff is difficult to pass, the crossbow arrow drags the rope and shoots to the other side of the cliff. If the grappling hook just hooks the rocky tree

At the fork, our soldiers will pass by the rope as soon as they stand, wouldn't it be swift?"

After he finished speaking, he added, "If the crossbow is not powerful enough, you can also use a bed crossbow. With the power of the bed crossbow, the crossbow can shoot a hundred feet away and can cross a dangerous cliff of a hundred feet."

Li Mengxi's fantastic ideas opened the eyes of Liu Bei and Guan Yu.

Li Mengxi has already made it very clear how to use crossbows or bed crossbows to build suspension bridges. Without thinking too much, Liu Bei and Guan Yu knew very well that this method was absolutely feasible.

Not to mention that Liu Bei and Guan Yu were deeply inspired, Li Mengxi couldn't wait to write down this good idea that took a lot of brain cells to come up with. If he forgets it tomorrow, it will be in vain.

"Speaking of the suspension bridge, I think the suspension bridge is also very useful if it is used vertically." Li Mengxi said with a frown.

The suspension bridge could still be erected. Liu Bei and Guan Yu were confused and asked hesitantly, "How can it be used easily?"

Li Mengxi organized his speech, looked up at Guan Yu and Liu Bei, and asked, "If you want to climb down from the height of the cliff, how should you climb down?"

"Choose a dexterous person, grab vines and climb rocks, and climb down carefully." Liu Bei answered.

On the side, Guan Yu twisted his beard and muttered, "You can have someone tie a long rope around his waist, and then climb the rope downwards."

Liu Bei said that he climbed down the cliff with bare hands; Guan Yu said that the people on the mountaintop pulled the rope and tied the waist of the climbing soldier. Then the soldier grabbed the rope and climbed down slowly after having a place of leverage.

Guan Yu's method was better, but Li Mengxi had a better method.

"To climb up and down, I have something - a centipede hanging on the mountain ladder." Li Mengxi said word by word.

The name Centipede Hanging on the Mountain Ladder sounds very powerful. Guan Yu opened his eyes slightly and asked, "What is the Centipede Hanging on the Mountain Ladder?"

"The so-called centipede-hanging mountain ladder refers to a hanging ladder with more than hundreds of steps. Because the hanging ladder is as slender as a centipede, it is called centipede-hanging mountain ladder."

As he spoke, Li Mengxi took out the short knife from his waist and randomly drew a hanging ladder on the ground.

After finishing the painting, he saw that there was no difference between the hanging ladder and the ordinary ladder drawn on the ground, so Li Mengxi turned around and thought about it, and drew a comparison object above the ladder.

The comparison object is a few cliffs.

After these few strokes of the cliff painting, the whole picture looks like a long ladder hanging from the cliff.

"Look, this is the Centipede Hanging Mountain Ladder. It is extremely dangerous to climb down from the cliff without using anything with bare hands. And even if you climb with the help of a rope, the only place you can put your body on is your hands, which is still inconvenient.

And if there is this hanging mountain ladder, the ladder is hundreds of steps long, and the high cliff hangs down to the bottom of the valley. Soldiers can climb along the ladder. They can hold the ladder with both hands and step on the ladder with both feet. Therefore, there is room for both hands and feet to borrow strength.

, much more stable and convenient.”

Li Mengxi spoke slowly.

Liu Bei and Guan Yu both looked surprised.

Needless to say, the name Centipede Hanging Ladder sounded so powerful that Liu Bei and Guan Yu mistakenly thought it was Li Mengxi's apprentice, who learned it from that mysterious teacher.

In fact, the Centipede Mountain Ladder is just a ladder, and its structure is the same as the ladder used by helicopters.

The reason why we use the name Centipede Hanging Ladder is because I once read a little bit of the novel "Ghost Blowing the Lamp". Tomb robbers often go down to deep mountains and huge valleys to rob tombs. A hanging ladder that is hundreds of meters long can help.

Grave robbers can easily reach places that are difficult to reach with other tools.

Speaking of which, the elevator is not a high-tech gadget. It must have existed in the Han Dynasty.

However, popularity and ideas should be a problem.

For example, the straight plow was already very common in the Tang Dynasty, but until the 20th century, after liberation, many people in remote mountainous areas still used primitive wooden straight plows. You know, from the Tang Dynasty to the 20th century,

Thousands of years have passed, and the Quyuan plow technology has also been spread for thousands of years. Despite this, there are still places where it has not been popularized.

The efficiency of technological dissemination in ancient times was really unbearable.

Therefore, although hanging ladders are not a high-tech technology, they have not been widely used.

Was the hanging ladder technology commonly used in military affairs during the Han Dynasty? The answer is no.

During the Later Three Kingdoms period, Deng Ai sneaked across Yinping and encountered dangerous cliffs and deep valleys. He couldn't make it through, so he wrapped himself in a blanket and rolled down the hillside.

Why did you just roll down? Because Deng Ai didn't bring a mountain ladder.

Otherwise, you need to have a mountain ladder so that you won't have to roll down with a narrow escape every time you encounter a valley.

This hanging mountain ladder alone is enough to be placed in the martial arts summary.

According to my impression of the ghost-blow-out movie, when the tomb robbers were fighting, the two gangsters put down the ladders they were carrying behind their backs. The ladders rolled open with a crash, and the ladders could be unfolded very long.

It can be seen from here that the hanging mountain ladder can be made lightweight. After all, people do not weigh much. If the herb collector is lucky enough to catch a handful of dead vines in the cracks of the rocks when falling off the cliff, he might be able to pick them up.

After all, a dead vine can withstand the weight of an adult's body, so a finger-thick hemp rope and strong wooden steps can withstand the weight of a human body even more.

In summary, although he has not yet begun to make a mountain ladder, Li Mengxi believes that a mountain ladder that can be hung up and down with a vertical height of one to two hundred meters can be used as individual equipment.

It has been decided before that each hundred-man team should be equipped with a large net. A large net weighs dozens of kilograms. Carrying the net and bedding cannot be carried on the back.

Similarly, if a cook carries earthenware pots, pottery, grain, etc., he cannot carry bedding.

It is the most ideal situation for one person to carry one bedding.

In fact, it's no problem for two people to share a bed.

In other words, in the extreme state, a hundred-man team only needs fifty people to carry bedding, and the remaining fifty people can carry grain, three to two hundred arrows, several hundred kilograms of grain, or a bag weighing dozens of kilograms.

A large net, or a roll weighing dozens of kilograms to hang from a mountain ladder.

Add the mountain ladder as auxiliary equipment to the soldiers' equipment sequence. The load-bearing capacity of an individual soldier is limited. Adding equipment will naturally squeeze the carrying capacity of other items, because to carry the centipede mountain ladder, you must have a

Soldiers could no longer bring bedding, so they had to share a bed with others.

If you need to carry more equipment, the number of beds will be reduced, so the comfort level of soldiers will be reduced when they rest.

But this isn't a big problem.

Hanging on the mountain ladder can be regarded as a secret technique of military strategists.

Guan Yu had a problem with this, that is, the ladder was hung up, and then the soldiers climbed down the ladder one by one. When everyone climbed down, how to retract the ladder?

If it is said that the last person should be left to collect the ladder, what should the last person do?

This question left Li Mengxi unable to answer.

That's right, unless you throw down a ladder after crossing a mountain, otherwise, it's really difficult to recover the ladder.

There is no need for a ladder to cross a mountain. This method is not feasible. If there are many mountains, there will be no ladder to cross the mountain. Before going very far, the ladder will be gone.

The hanging mountain ladder is still an important strategic tool and must be recovered.

When it comes to recycling, we face the question raised by Guan Yu - how should the person who finally recycled the ladder get down?

As for the person who stays at the end, it would also work if he untied the ladder, tied a rope to the tree, and climbed down by himself.

Although the rope cannot be retrieved, it is equivalent to using a less important rope in exchange for a very important hanging ladder, which can be regarded as a way to reduce logistical pressure.

Alternatively, technical means can be used to solve it.

Is there a technique that can be used to take down the hanging ladder after reaching the bottom of the cliff?

Li Mengxi thought hard. Even if he thought of mechanization and automation technology, he could not recall any technology that automatically retracts the ladder after it is hung on the mountain, and it does not retract upwards, but retracts downwards.

Unless there is some black technology, the ladder can be tied to the cliff and can be automatically untied without anyone having to untie it.

After thinking about it, the only strategy is to abandon the soldiers and save the horses. Use a thin, worthless and unimportant hemp rope. Each soldier can carry several more than one slender hemp rope to protect the precious hanging mountain.

ladder.
