The test of practice made Liu Ponu realize a truth, and his ideas were still a little too naïve.

If the technical requirements are not met, it is necessary to rashly promote trucks on a large scale to put them into the military, and of course good results can be seen in a short period of time.

But after a long time, the problem will start to come to light.

For example, the new army needs a large number of trucks, and on average every 12 people need to be equipped with a truck, the reason is of course the load of the truck itself.

From an operational point of view, after deploying the proportion of materials, it was enough for them to go deep into the desert to engage in a large-scale battle with the Huns.

At the same time, this is also the most mobile unit, there is no one.

There are too many benefits to count, but there are also many disadvantages, a large number of military trucks occupy a large amount of steel resources, which puts pressure on Dahan industry, which is just in its infancy.

In order to support the construction of the army, even the steel used for the curved plough has now been cut in half, although the efficiency has not decreased much, but in the long run, the durability is certainly not as good as the previous version.

The large number of construction military trucks also delayed the construction plan of tractors indefinitely, which also delayed the semi-mechanized cultivation of the Han Dynasty into the city.

At the same time, the domestic cargo movement plan was delayed, according to the original plan, the tractors worked in the fields during the busy agricultural season, and the rest of the time was used to transport goods to generate value.

Although it can also produce value after being put in the army, the value generated is different.

One is the invisible interest, the interest that requires the continuous investment of the imperial court, and the other is the interest that can be seen in real practice, and the interest that can support the rapid progress of various things.

And now another more troublesome problem has arisen, the mechanical wear is too severe, and the frequency of use will not be compared, after all, this thing will not be idle anywhere.

But the army needs the continuous investment of the imperial court, daily use, maintenance, are all required by the imperial court to pay, the army itself does not produce economic benefits, although the expansion of territory is also a benefit, and it is also a benefit that can benefit the eternals, but for the moment, he is a pure loss of money.

If it is used for agriculture or commerce, then the economic benefits generated by it are enough to support the consumption caused by this wear and tear, although it will still crowd out a lot of resources, but under the impetus of the economy, everyone is willing to accept this kind of effort and return.

And this time, Liu Ponu had to think about it carefully, and he had to plan to take a step back from the new army that had completed the motorized transformation and turn it into a quasi-semi-motorized army.

That is, the trucks in the army are only used for logistics materials, wounded soldiers, intelligence transmission and other purposes, and daily marching and combat need to return to the most primitive state.

In this way, the number of trucks in the army will be reduced by more than 80 percent, and the existing number of trucks will be enough to complete the restructuring of the army of 7 or 800,000.

If new trucks are not manufactured in large quantities for military service, and only key parts are produced for maintenance, the imperial court can afford this price, and the surplus production capacity can also be put into civilian use, so as to drive the economy and promote agriculture.

The cost of this is that the army will slow down, and the strategies and tactics that have been studied before will have to be temporarily mothballed because they are too advanced, and all new armies will need to study new tactics and adapt to the new environment.

Most importantly, in the field, the troops will no longer have a crushing advantage over the enemy's cavalry units.

Similar to the previous battle scene in which Han Yannian defended more than 100,000 Hun main cavalry with 20,000 people outside Chigu City, and his own casualties were only 100 and the annihilation of more than 40,000 enemy troops could no longer happen.

No one wants to go back from something more advanced, especially after experiencing his exhilaration.

However, after this battle, the Han Dynasty could stop for a short time, and there were almost no decent wars for them to fight next, and there was no opponent in the world who could make them pay as much attention to the Xiongnu.

Slowing down may not necessarily be a bad thing......

Thinking of this, Liu Ponu immediately wrote a letter, explained in detail in his heart what he saw and his thoughts on the next arrangement, and then ordered someone to send the letter back to Chang'an as quickly as possible under the premise of ensuring safety!

Tossing is not necessarily a bad thing, as long as you can recognize the problem in time and make corrections, it is a good thing on the whole.

Although Liu Ponu came through time, the traverser will also make mistakes, and what Liu Ponu made is just an empirical mistake.

He only knew that the mechanized troops were very cool and their combat effectiveness was very strong, but he ignored the current real level, although he forcibly made it, but if he didn't want to consume the last bit of energy of the big man, he had to give up those beautiful ideas in his heart and push the facts in a direction closer to reality.

……

Just when Liu Ponu was full of emotion because of this trip, and began to tinker with his future plans.

About 500 miles northwest of Akaya Castle, she ushered in the most solemn day in her history, and welcomed her most important guest.

Ever since Dalu learned that Liu Ponu, the crown prince of Han, had sent an envoy to his tribe, the whole person was extremely excited.

During this period, he constantly sent people to pay attention, and when the little mule was still dozens of miles away from his royal court, Da Lu took almost all of his henchmen to greet him.

And this is more than 30 miles away, and the smile on his face is a little unpredictable to look at, and Dalu's appearance is as if he can't go directly to Chang'an to pick up the messenger.

"I heard that you want to lead your troops to join the Han?" The little mule made a gesture of being on top.

Don't look at this kid who doesn't have a positive shape on weekdays, but on some occasions, he is also full of force.

After all, he was born with Liu Ponu, if he doesn't even know this bit of housekeeping skills, then how can he be embarrassed to say that he is Liu Ponu's henchman?

Besides, are we pretending to be this for ourselves?

Not!

As a Han Chinese, thousands of miles away, his words and deeds represent the entire Han Dynasty.

Today's big man is strong, so naturally he should put on a tough posture, otherwise it will only make some people look down on him, this is not scolding, but some people are so cheap, if you are good to him, he will bite you, but if you beat him three times a day, he will nod when he sees you, and he will bite whoever you let him bite.

"Han envoy, in fact, I don't just think so, if I can, I hope to be able to lead the entire Wusun to join the Han Dynasty......" Dalu immediately smiled tentatively.

"It's a pity that you are not the king of Wusun, and you can only represent your clan, but not the entire Wusun!" The little mule smiled and exposed Dalu's old bottom in public.

"The Han envoy doesn't know something...... "Da Lu is not angry about the little mule's behavior of revealing the old bottom, although it is indeed a little unhappy in his heart, but who makes himself weak, who makes himself ask for others?

Besides, what he said is the truth, what's the use of being angry?

In addition to angering the Han envoys, angering the Han prince, and angering the entire Han Dynasty, what good is it for yourself?

"In fact, according to the rules of Wusun, my brother died early, and after his death, I will be the first heir, so this throne should have been mine, but my father thought about his son, and looked at the young Jun Su Mi and felt partial, so he broke the rules and forcibly passed the throne to Jun Su Mi, and the strength in my hands was not enough to fight against the entire royal court, but I was not willing to submit to them, so I could only bring my subordinates to live here." Da Lu presented himself as a victim, because he knew that the Han people were the most particular about these things.

Many times, they prefer to help the weak, and they prefer to help the oppressed party.

And this is completely different from the grassland, the grassland is the jungle, there is no right or wrong at all, weak is guilty, weak should be bullied, and no one will sympathize with you and help you because you are weak, they will only think about how to annex you.

In the same way, if they do not find a way to strengthen their tribe, then one day when they encounter a tribe that is even more powerful than them, they will be the ones who will be annexed.

The current Dalu does not know whether Jun Sumi will attack him one day in the future, and the Han Dynasty is coming, they are about to rule the entire Western Regions, and the Xiongnu in the north will also be annihilated by them.

This also means that in this land, it is impossible for Dalu to have the opportunity to annex any tribe to increase his strength.

And once Jun Sumi launches an offensive against himself, then he can only become bigger and weaker, and then be eaten away little by little.

At this moment, Dalu has no way to retreat, and directly taking refuge with the Han people and seeking refuge from the Han people may be the only chance for Dalu.

And it just so happened that Dalu didn't seem to have a particularly pleasant conversation when he heard that they were in Akatani Castle before, and Dalu also made some preparations for this.

So he took out a strange-looking, but very brand-new bamboo slip from his bosom, handed it to the little mule and said: "Han envoy, I recently found this thing when I was sorting out the family property, I inquired about it, and found that this thing has been here for a long, long time, and no one can say how long, the person in charge of keeping him said that this is something that his grandfather told him to keep well when he was very young, and his grandfather took it over from his grandfather's grandfather, and his grandfather's grandfather ...... from him."

Looking at the brand-new bamboo slip in Dalu's hand, the little mule scolded shamelessly in his heart, if this thing can be more than a year, I will eat upside down, and what about my grandfather, can you Wusun people pass on six or seven generations a year?

Even if it's a donkey from the production team, he doesn't dare to give birth like this!

The little mule took the bamboo slip, opened it lightly and looked at the written record on it.

Well, the distorted small seal script says that they are descendants of the Xia clan, and they migrated from the Central Plains to the vicinity of Dunhuang more than a thousand years ago in order to escape the war......

After reading the above record, there is only one idea left in the whole mind of the little mule, the owner who can make this thing is definitely a genius, the kind of genius that is so good that it explodes......
