For Wusun's ally, Liu Ponu felt that there was nothing to say.

You say he's useless, he's really useful.

But you say he's useful, but it's not as big as you think.

However, during the period of Emperor Xuan of the Han Dynasty, Wusun did send troops to support part of the Han army's operations, of course, it was because Princess Xie Wu was there, and there was no need for the Wusun people to fight the Huns, the main force of the head-on confrontation was still the Han army, and the Wusun people were only responsible for flanks and support.

There are many examples of harmony in history, especially in the Han and Tang dynasties, the number of relatives is the largest.

Liu Ponu is not an expert in this area, so there is no way to judge the good or bad, and the peace in the early Han Dynasty was mainly based on seeking peace time to recuperate.

The Tang Dynasty's harmony was mostly based on cultural export, but then again, how much influence can the cultural output of sending a princess over to be harmonious?

Anyway, Liu Ponu is not a pro-faction, so the only time he handled the matter of pro-affinity, he chose to follow his own ideas and agree to the application of the eldest niece Liu Xijun, who was older than himself, to return to Chang'an.

The army traveled mightily, and the 100,000-strong army was equipped with as many as 10,000 vehicles.

And what is the concept of 10,000 cars?

On average, each car is calculated according to the length of six meters, and the 10,000 cars are connected and arranged together, which is also the length of 60,000 meters.

And in reality, there is a certain distance between the two cars, and the current road conditions do not allow them to drive side by side, so the length of the entire team is even more than 120,000 meters, well, 120 kilometers.

Fortunately, 100,000 people is not a small number, and there is no place around Chang'an where so many people can be put down, so the barracks of the new army are all over the territory of Jingzhaoyin.

Before Liu Ponu officially sent troops, the troops in other places had already begun to set off one after another, and after passing through the Hexi Corridor and entering the territory of Dunhuang, the road could not become a factor restricting the march of the troops.

If you have never been to the Hexi Corridor, you will never be able to experience the magnificence here, and you will never be able to feel the magic of nature.

There are high mountains on the left and right sides, only this plain oasis in the middle, after more than ten years of development, it has been detached from the most primitive style.

But it is still sparsely populated, but this does not affect his status in Dahan.

Since the recovery of the Hexi Corridor by Huo Quai, it has become the horse farm of the Han Dynasty, and since then, it has bred one war horse after another, carrying one after another Han soldiers and opening up one dream after another.

It's just that after Liu Ponu proposed the new army system, the horse farm here has gradually been abandoned.

Although it is not completely deserted, because the imperial court no longer needs more war horses, it is no longer as prosperous as before, and it is difficult to see thousands of war horses galloping and running.

Looking at this scene, Liu Ponu couldn't help but think of the dream of the Hexi Corridor.

"Brother Nu, the situation seems to be a little not good......" As soon as the troops entered the territory of Wuwei County, the little mule looked at Liu Ponu who was enjoying the beautiful scenery with a sad face.

Liu Ponu can have the heart to see those beautiful scenery, and even look forward to some beautiful pictures.

But as a person with a lot of pressure in his heart, the little mule knew that he was not qualified to enjoy these pictures.

At least now he doesn't have this qualification, in terms of qualifications and ability, he is not enough to sit in the current position.

All this is just because of shit luck, just assigned to a unit with Liu Ponu, and what's even more strange is that one of the two is from Yangling, and the other is from Kanto, even if it is a temporary patchwork, in order to ensure combat effectiveness, in the past, most of them were fought between Guanzhong and Guanzhong, and Kanto and Kanto.

It's rare to have this kind of cobbling together between two different people, and of course, that's just the norm.

When it came to the battlefield, the casualties of the troops were huge, and in order to achieve a smooth battle, it was normal for the generals to put together the remaining unsatisfactory troops to make a full formation, and it was in this situation that the little mule and Liu Ponu were put together by mistake.

If it weren't for Liu Ponu's sudden development, the little mule wouldn't know where the cat was at this time.

Of course, later he realized that the little thing he committed at the beginning was not a problem at all, no, he was considered a crime before, but he was used by Liu Ponu to cite filial piety, and he passed it specially.

But in any case, the little mule can have today, relying on Liu Ponu's support, so the little mule has not forgotten his task since he set off.

"There is no problem with the section from Chang'an to Chencang, but it is too difficult to go west from Chencang to the middle of Wuwei......

"The trucks equipped with our army are all high-power, even then in some places you need auxiliary vehicles to help you come up, and the road is very narrow throughout the section, and the vehicles in many places can only walk carefully, I have observed a lot along the way, even so, the probability of the vehicle touching the mountain is also very high."

"If this road is an emergency, it is naturally not a big problem, but if you want to use it for a long time, or even make sure that you need a car to run every day, then the problem is big." The little mule said with a sad face.

Liu Ponu did not question the little mule, and he also saw the situation along the way.

The little mule was talking about the section of the road over the Qinling Mountains, which, according to the previous descriptions, was more difficult to walk in the early years.

It is still because of Huo Quai's recovery of the Hexi Corridor, and after more than ten years of continuous repairs in various places, it has its current appearance.

If it is only used for ordinary carriages and ordinary troops, it is not a big problem, but for a big guy like the New Army, which has tens of thousands of trucks, it is not so friendly.

"Find a suitable place to build roads and bridges!" Liu Ponu said directly, although he didn't want to, but he couldn't help it.

You have to walk it once to know how difficult it is, the speed of the truck cannot be fast, the driver's attention must be fully concentrated, the slightest mistake, the slightest mistake can hit the mountain, or the worst fall into the canyon.

What's worse is that there are some places where you have to cross the mountain, but the mountain is so high and so steep, people can turn over, what about the car?

So you can only take a detour, and it is a long way, often in order to bypass a mountain, you need to walk several kilometers more, this piece stretches for hundreds of miles is such a mountain, can you experience the feeling of bewilderment around and around?

"If you can't repair it, the big man can't ......afford to repair it," the little mule shook his head and continued: "Don't look at this road, it looks like it's only a few hundred miles, but I've calculated, the road we detour is not close at all, plus the environmental conditions here, if we really build a road, I'm afraid the price is enough for us to build a road from Chang'an directly to the Central Plains, and then to Yangzhou." ”

"If you can't repair it, you have to repair it, if you can't do it in one year, you will have five years, and if you can't build a wide road, then you should mainly widen it, at least so that the trucks can stagger here, even if they can't be staggered, they must be able to pass here calmly."

"If this road can't be built, the Han's control over the Western Regions will always lack something, and over time, the efforts made by the Han over the years will gradually disappear."

"So this is not just a road, he is also the foundation of the Great Han's rule over the Western Regions!" Liu Ponu said firmly.

Are you kidding?

As the ancestor of the infrastructure madman, you told me that I couldn't build a road?

Although I can't do it as crazy as the infrastructure madness of later generations, it's okay for me to widen the existing road, right?

I can't afford asphalt pavement, and I can't afford cement pavement, but with the current conditions, do you need to use that kind of high-grade pavement?

As long as it is smoother, there is not even a wheel on the wheel, so there is no need for such a high flatness, the gravel and soil on it are thrown directly on it, and this thing can increase the grip of the wheel.

That's right, today's wheels are all made of steel because of the lack of rubber wheels, which is very luxurious.

In order to cope with the fact that the surface of the wheel will be too smooth after a long period of use, some steel spines about one centimeter long are cast together in a circle on the surface during casting.

And the advantage of this is that the better the road, the more uncomfortable it is to walk on, and the worse the road, the more comfortable it is to walk on.

Especially when running on the grassland, it's as free as the wind when running on the prairie, like a sprinter's spikes on a boat.

It was difficult for the little mule to understand why Liu Ponu had a soft spot for the Western Regions, and why he had to build this road at any cost.

Compared with the emperor's hobbies, the little mule still feels that the emperor's hobbies seem to be more acceptable.

At least it didn't take him so many years to build a palace, and the emperor didn't finish building one and then another, but building roads is different.

"Such a long road, once the construction starts, I'm afraid it won't be able to be done without 1 million people, and the food can be temporarily not too worried, but the money is not enough, I don't know how much the court can take out, anyway, the money in the workshop is too far from this......" The little mule still shook his head.

"This matter is not as complicated as you think, when you encounter a suitable place, you can directly take the explosives to blow up, and after the explosion, you can directly use the engineering truck to push, and the waste does not need to be transported away, just find a place nearby to pile it there, and when the road is repaired in the future, you can directly go to the scrap yard to transport it, and you don't have to toss back and forth." Liu Ponu said with a big grin.

The detour must be detoured, and the tunnel or something is not impossible to consider, but it can't be too long, and the tunnel that moves more than ten kilometers to future generations can't be dug out even if it dies.

In addition, there are a lot of auxiliary stations here, which are mainly used to help passing vehicles climb the hill and respond to emergencies.

"This road must be repaired, this is a road that can benefit for thousands of years in the future, and it is also the lifeblood of the Han Dynasty......"
