During the march, many things cannot be anticipated in advance.

A rack truck loaded with grain broke down halfway.

Guan Yu went to check, and Li Mengxi followed him.

The grain truck had unloaded the animals and was parked on the side of the road. The truck was tilted up and down. Several bags of grain rolled on the ground. One of the bags was broken and the grain was scattered all over the ground.

When you were still far away, you could see that the wheel on one side of the car was broken. When I walked over, I discovered that not only the wheel was broken, but the axle was also broken.

Li Mengxi was unfamiliar with many things in the late Han Dynasty, but carriages were not among them.

Rack carts, or pallet carts, were still common in rural areas in later generations.

Li Mengxi was curious and wanted to take a closer look.

Guan Yu was discussing what to do with Xiang Yong, who was in charge of the grain truck. Li Mengxi took his younger brother, and the two of them squatted there curiously, pulling on the wheels and studying them.

In his previous life, even in rural areas, Li Mengxi had seen that although the bodies of carriages were mostly made of wood, the wheels were all made of iron axles and rubber wheels. He had never seen wooden wheels.

The broken wheel in front of you now is made of wood.

This is the reason why Li Mengxi is curious.

Looking carefully at the structure of the wooden wheel, the wheel completely fell apart and split into several pieces.

The structure of the wheel is like an entire wheel hub made up of four arcs.

When I think about it, it seems that if it is processed from wood, it is indeed much simpler to separate the wheel into four parts than to make the whole wheel.

In primitive society, the most primitive wheel was to saw a piece of a relatively large tree trunk and then use it as a wheel.

But such wheels are not only heavy, but also have uncontrollable size and shape.

A more advanced technology is to use square wooden strips bent into wheel hubs, with wooden spokes in the middle. These spokes play a role in supporting the wheel hub, just like the steel spokes of bicycles in previous generations.

Compared with the original solid wood wheels, the wheels made by wood processing technology can be made in any size and are no longer restricted by the diameter of the tree trunk, and are lighter and stronger.

Li Mengxi looked at it for a while and felt that the wheel structure was a bit complicated.

There is no spare wheel at all. This wheel is broken. What will happen to a load of grain?

As far as Li Mengxi knew, when he sent out the army, he brought more than a hundred vehicles, all of which were fully loaded, and no one was empty.

Li Mengxi couldn't think of a solution, so he went to see Guan Yu how to deal with it.

Guan Yu directly asked the marching team behind to stop, and asked the country warriors to come over, carry the grain to other carts and throw it on.

There is strength in numbers, and in a short time, a cart of grain has been moved.

"Xi'er, let's go." Guan Yu called to Li Mengxi who was still watching and told him to go.

"You don't want this truck?" Li Mengxi pointed to the grain truck parked on the roadside in surprise.

Although one wheel of this car is broken and the wheel axle is broken, the body and the other wheel are still good, so why throw it away? Isn’t it money?

Guan Yu smiled silently, "I didn't bring a carpenter with me when I left, so I can't repair it. Let's go."

Li Mengxi seemed to feel sorry for Che, which Guan Yu found funny.

Oh, it's because I didn't bring the carpenter with me when I came out. Li Mengxi suddenly realized.

"Then why don't you bring a carpenter? If there is a carpenter, can this car be repaired? How long will it take to repair it?" Li Mengxi asked again.

Guan Yu was speechless.

——

Not long into the march, one of the cars broke down.

When he returned to the carriage and continued to march, all Li Mengxi could think about was the carpenter.

When marching, you have to take a carpenter with you.

Because didn’t the car just break down?

But why didn't Guan Yu take the carpenter with him before leaving?

Didn't you expect that?

From now on, we have a long way to go, and we may not know when another car will break down.

Also, if there is no village in the front and no store in the back, where can I find a carpenter?

Furthermore, if the wheel is broken, how do the carpenters repair the wheel? Whether they repair it quickly or not, it still takes a long time to repair it.

Li Mengxi didn't know anything about this issue related to the march.

——

Once the work of teaching Xiangyong to learn calligraphy begins, it is completely impossible to stop.

Speaking from a higher level, Liu Bei and Guan Yu attached great importance to this matter.

Since they began to teach calligraphy to the village heroes, Liu Bei and Guan Yu began to gather the officers to learn after setting up camp.

Under this momentum, whoever says that if you stop learning will be unhappy.

Speaking further, when given the opportunity to learn calligraphy, the soldiers cherished the opportunity and had an extremely positive attitude.

It is true that there are a small number of knowledgeable people, or people who are more or less literate, who question whether the strange symbols taught by Li Mengxi are characters. However, after Liu Bei's explanation, the village heroes all understood what the strange symbols they learned were.

It’s an amazing thing. It’s Guigu’s divine arithmetic. Most people want to learn it but there’s no place to learn it.

So everyone was very motivated to study.

When I first taught calligraphy that day, I used the back of the handsome flag as a blackboard and wrote with lime water.

But firstly, it will stain the flag, and secondly, the flag is not easy to fix, and it has to be held by someone, which is inconvenient.

So it was improved.

Li Mengxi found a particularly beautiful shield.

That shield was the best and largest shield found in the army, and was called the "Rhinoceros-faced Shield."

This shield is incredibly exquisite. The shield surface is regular and slightly curved. The shield is also coated with some black paint. The paint surface is very complete and smooth. Under the sun, the paint surface is vaguely black with colorful colors.

It is said that this thing is lacquerware, and some snail powder is added to it, so it shows a white color.

Anyway, this is a high-end weapon seized from the Yellow Turban Army. Different from ordinary weapons, this thing is a ritual weapon.

The shield is large enough, especially the shield surface is smooth and black, making it perfect for use as a blackboard.

Therefore, this shield became a special blackboard.

On the shield, ten numbers are written from 0 to 9.

Li Mengxi is still a military instructor, and the teaching work is entirely dependent on him.

As usual, Li Mengxi asked the nine numbers from beginning to end, and the village heroes answered fluently.

Then, I randomly picked one out of order.

The brave villagers were still able to answer immediately.

Very good, it shows that the village heroes have memorized all the glyphs of the ten numbers.

There were eleven centurions in the army. Guan Yu dismissed six of them on the first day because some of them could not remember their characters.

There are five left.

If you want to kill a chicken to scare the monkeys, or catch an example, it is best to use the centurion to establish your authority.

Li Mengxi learned this from Guan Yu.

Therefore, every time he asked a routine question, he would definitely call out the remaining five centurions and ask them one by one.

No, five centurions were called out by Li Mengxi again.

The centurion accepted Li Mengxi's question with some anxiety.

"What is this?" Li Mengxi took his stick and pointed at a number on the shield.

The centurion who was questioned was a middle-aged man with a moustache and a somewhat fierce look. But at this time, the man was nervous and sweating on his forehead.

"Yes...it's five!" The centurion stuttered nervously.

"Well, that's right. What about this?"

"It's seven."

…

Every time Li Mengxi asked a question, the centurions were under great pressure and inexplicably frightened.

To be honest, they and Guan Yu have never been so nervous when fighting with others in the battle.
