The adults are very tall. Li Mengxi is still a small child. It is not easy to climb a ladder that is as high as the adults.

"Xuan Degong," Li Mengxi looked back at Liu Bei who was following him, "Put me up." Li Mengxi helplessly pointed to the ladder and said.

Liu Bei smiled, clasped his strong hands together, grabbed Li Mengxi's left and right armpits, and lifted Li Mengxi up the ladder.

Li Mengxi stood firm on the ladder and said, "Torch." He stretched out his hand and asked Liu Bei for a torch, as if Liu Bei was his own soldier or servant.

Liu Bei quickly handed the torch in his hand to Li Mengxi.

After getting the torch, Li Mengxi put it under his feet, bent down and carefully looked into the light to see if the shields on the ladder were arranged tightly.

Without looking at it, he thought that the shield cover would be very dense and have a good effect of blocking arrows. After a closer look, Li Mengxi saw some minor problems.

The shields are placed one next to the other and are not placed tightly at all.

Arrows are as thin as chopsticks, and can slip through a slight crack and hurt someone.

On the battlefield, any negligence can be fatal.

Li Mengxi lowered his head to observe carefully. It didn't matter. His head was close to the torch. He suddenly clicked and the hair on his forehead was burned and rolled up.

Li Mengxi was startled and almost dropped the torch.

"Xi'er? Are you okay?" Liu Bei, who was following Li Mengxi step by step to prevent Li Mengxi from falling, asked worriedly.

"Nothing." Li Mengxi touched his hair and eyebrows, "The torch burned my hair." Li Mengxi said extremely depressed.

When the village warriors carrying the ladder heard that Li Mengxi had burned his hair, they laughed rudely in a low voice.

Walking on the ladder, walking forward bit by bit, looking at the shield's coverage as he walked, Li Mengxi found that compared to the square shield, the round shield had poorer coverage.

There are always some big gaps exposed at the corners where the round shield touches other shields. Unlike the square shield, the two square shields fit together tightly.

"I'll tell you."

Li Mengxi stood on the ladder, looking at the torches around him, like a veteran galloping on the battlefield.

"There is no need for a round shield. The round shield is exposed on the ladder with a big gap and cannot be fully covered. If we can use a square shield, we will use a square shield."

As he spoke, Li Mengxi took off the round shield covering the ladder.

Seeing that Li Mengxi said he wanted square shields instead of round shields, Liu Bei helped Li Mengxi gather the square shields from other teams.

Liu Bei passed the shields one by one, and Li Mengxi received the shields one by one. The two of them seemed to be building a house, handing out bricks, and they cooperated tacitly.

Every time Li Mengxi took over a square shield, no matter how big or small, he would stack them up from the beginning.

There is no longer the unsociable round shield. Regardless of the size of the square shield, if you press the corners a little, you can cover it tightly.

Just as he was carefully stepping on the ladder bars and swinging in, Li Mengxi suddenly slipped and one of his legs missed the step and fell under the ladder.

"Xi'er!" Liu Bei hurriedly put down the shield in his hand and went to help Li Mengxi.

Fortunately, there was someone standing under the ladder. With a little lift, Li Mengxi pulled his legs out and stood up again.

"Nothing." Li Mengxi waved his hand towards Liu Bei, indicating that he didn't need to be nervous.

After standing firm, Li Mengxi looked down and saw that he had stepped on something so slippery.

At first glance, Li Mengxi saw that the horizontal bar he just stepped on was cut from a round branch.

Li Mengxi couldn't help but look at his feet a few more times. Li Mengxi suddenly figured out some issues.

It's friction!

Rolling friction is less than sliding friction.

Because it is round, it is more slippery. Therefore, if you put money in your pocket and circle it into a cylinder, the money will easily slip out of your pocket, and then the money will fall. The correct way to put money is to fold the money in half

put.

If the steps of the siege ladder are round, your feet will slip easily.

Another small oversight was discovered by Li Mengxi.

Then continue stacking shields until the ladder is full.

At this time, under the ladder, the villagers carrying the ladders lowered their heads and looked sideways. The light from the torch in Li Mengxi's hand gave the villagers a reference.

Looking from the bottom up, the shield is so dense that no light can penetrate it.

(This pile of shields is like a roof...) The village heroes thought in their hearts, and at the same time, they felt extremely safe in their hearts.

"Boom!" Li Mengxi jumped down from the ladder, stood up, and patted the dust on his hands.

"Mr. Xuande, I know why the hilts of your male and female swords have eight ribs."

The question that has been unresolved for a long time and that I have been pondering for a long time has found the answer tonight on the siege ladder.

"Oh?" Liu Bei was stunned for a moment, and then asked in surprise, "Why?" he asked with a smile.

"Because the round handle is slippery." Li Mengxi replied with a smile.

Once upon a time, a long time ago.

Li Mengxi saw the legendary male and female swords. At that time, he saw that the handles of Liu Bei's male and female swords were similar to the handles of table tennis rackets. At that time, Li Mengxi felt strange and asked Liu Bei why he was like this, but Liu Bei couldn't answer.

This issue has been unresolved for a long time.

Unexpectedly, I got the answer unexpectedly tonight.

This is called walking through the iron shoes and finding nowhere, but there is another village with dark flowers and bright flowers!

The horizontal bars of the siege ladder and the hilt of the sword should not be cylindrical, as they would be too slippery.

It seems that the round handle of the sword is not conducive to actual combat.

Li Mengximing realized a little knowledge about weapons.

After speaking, Li Mengxi called on the village heroes to lower the ladder and place it on the ground.

Then, Liu Bei, Li Mengxi and other village heroes gathered around.

I saw that on the ladder, shields were arranged side by side from beginning to end, tightly.

"Look, everyone, let's put a square shield on top. The shield is so tightly covered that when we attack the city tomorrow, we can block 60% to 70% of the arrows shot from the city wall."

Li Mengxi introduced the tortoise-shell siege ladder he invented to the village warriors.

Li Mengxi was very satisfied, and so was Liu Bei. The most satisfied were the local warriors who were going to fight tomorrow.

They were whispering around the tortoise-shell siege ladder. This thing made people feel safe at first glance.

Li Mengxi said that he could block 60% to 70% of stray arrows, but the village heroes themselves thought that they could block 100% of them.

Another small tactical improvement successful.

"Lu Li! Come here!" Li Mengxi called the carpentry technical consultant who was staying here, the carpenter Lu Li.

Lu Li trotted over.

Li Mengxi kicked open the shield on the ladder, exposing one step.

This chapter is not over yet, please click on the next page to continue reading! "Look, here at the horizontal bar, if the horizontal bar is round, it is easy for the foot to slip. When climbing a ladder to attack a city, life or death can be a matter of seconds. If a foot slips and is delayed, it may

Someone will die.

So I want to ask, can all the horizontal bars be cut into square shapes?" Li Mengxi asked.

"Yeah." Lu Li hummed.

"How long does it take to fix the ladder?"

"In a moment." Lu Li replied.

Okay, another moment.

"Okay." Li Mengxi looked at the circle of village warriors, "Everyone, carry the siege ladder to the carpentry camp, modify the ladder, and then carry it back."

By changing the ladder, I no longer need to practice, and I can finally take a break again.

The village heroes were in high spirits and ran away carrying the ladders.

After all the village heroes left, Li Mengxi groaned and sat on the ground, his legs hurting from standing.

Liu Bei was not much better. After sitting down, Liu Bei couldn't help but rub his calves with his hands.

"Xi'er, you've worked really hard tonight." This was the second time Liu Bei showed his gratitude to Li Mengxi.

"Don't be so open to outsiders," Li Mengxi shook his head, "I am not an outsider. I am happy to serve my own soldiers."

This sentence was so frank that Liu Bei sighed inwardly.

Carpenter Lu Li said that changing the round bars of the ladder to square ones can be done in a short time.

Although this man is dull, he is very reliable.

It was said that it was a while, but it really didn't take long. The village heroes came back carrying the modified ladder.

Li Mengxi just sat down for a while and had to get up again.

Taking Liu Bei's extended hand and using his strength to stand up, Li Mengxi skillfully arranged training for the local warriors.

"That's almost it. We still need to practice running. After another ten rounds, let's take a break and start practicing the next thing."

"Okay." The village heroes responded loudly.

Seventy steps, ten rounds of running, not too tiring.

To attack a city with a siege ladder, you just carry the ladder and rush to the edge of the city, then put the ladder up against the city wall, and then people climb up the ladder.

But if divided carefully, the siege ladder siege can be roughly divided into three stages - the first stage is to carry the siege ladder to the bottom of the city; the second stage is to put the siege ladder up and lean it firmly against the city wall.

, in the third stage, the soldier climbs up with his shield on his back.
