A caravan in the northwest moved silently, wrapped tightly in dark robes, and this caravan was the transport team formed by Li De.

The carriage was laden with goods, but the speed did not slow down.

The lord of Yujun, who was in the middle of the team, looked at the modified carriage and was amazed, and said in his heart that if all the transport carriages of the Great Sui Dynasty were like this, wouldn't the transportation speed save transportation time.

Li Decai will not satisfy the curiosity of the Yujun Lord, the Li family's carriage has been improved by the Lu family brothers with a lot of effort, and the simple bearing on the car bearing has cost money to build.

Don't look at the horse-drawn carriage only in kind, the carriage is a Sima pull carriage, because the bottom of the carriage is also added to the load-bearing strip, which not only makes the carriage more sturdy, but also improves the overall load.

Ordinary carriages are all one horse, and those who go long distances will rotate with two horses, after all, it is not suitable for all carriages to be built with so much space to support two horse-drawn carriages.

In fact, according to his requirements, he wanted to build a four-wheeled carriage, and the advantage of the four-wheeled carriage was that it could reduce the weight of the horses and reduce the burden on the horses.

The disadvantage is that it cannot achieve efficient shock absorption, it is very dangerous if the speed reaches a certain limit, and if it is pressed against the stone road, it may overturn.

And there is also a disadvantage that it is expensive, but it is not just four wheels connected together, in fact, ancient European carriages had all kinds of auxiliary wheels and other things.

From a scientific point of view, the installation of various auxiliary tools is the application of science and technology, but Li De does not have so much time, and being able to have fifteen modified carriages is already the greatest improvement.

The Lu brothers have been busy with the salt mining workshop recently, so for now, it can only be like this, but fortunately, the load of the carriage is very gratifying.

In addition, each of them had one person and two horses, and two spare horses were tied to the back of the carriage, which could be replaced when they were on the road continuously.

Horses carry the necessary supplies on their backs.

This time, I didn't have the same freedom from Taiyuan Mansion to Chang'an, and I could barbecue and cook at any time with mutton ingredients.

All the people carried Hu biscuits, dried meat and some dried vegetables, and the taste was not unpalatable, but it was not delicious to say that it was delicious, after all, it was not beef.

In this era, it is very difficult to eat beef, cattle are the main farming tools, not just want to eat, and the beef that can be eaten is from the Western Regions, itself is used to generate economic value, without domestication and cannot be cultivated, the price is very expensive, not everyone can eat.

Another point is that even so, there are not too many cattle and sheep from the Western Regions that can trade to the Great Sui.

The people of the Western Regions are not stupid, and it is not possible to exchange all the cattle and sheep for money, after all, they are pointing to the development of animal husbandry, and if they sell all the livestock, what will they use to breed.

Therefore, they will maximize their profits, and the value of meat and fur, especially fur, is higher after processing, so the leather merchants of the Western Regions are very rich.

Li De and his entourage hurried continuously after leaving Chang'an, because they didn't need to be too vigilant near Chang'an, after all, there would be no thieves in the city to take risks.

Now it happened to be halfway through, the speed of the caravan began to slow down, and everyone was very tired from rushing continuously, Li De looked at the time, just in time to take advantage of the fact that it was not yet dark, and then live, cook, and rest.

"The caravan of the broad sea rested in place, and asked people to take turns on duty, eat and rest."

"Yes, I'll let you know."

Xiong Kuohai is obviously very experienced, and before he came out, he told everyone that the precautions are very simple, that is, all actions are under command, and Li De is the commander.

As soon as he heard that the people of the rest caravan immediately showed fatigue, Li De knew their feelings very well, and even Li De endured it, but fortunately, he had already made preparations.

In order to reduce the friction on the horse's back, a thick cushion was added to the simple saddle, which made him much better, and with the thick cushion, all the people in the caravan benefited.

What benefited the caravan personnel was that according to Li De's requirements, they used ropes to fix people on their horses when they were in a hurry, so even if someone fell asleep on the horse for two days, there was no fall accident.

However, this cannot be the case on the next mile, after all, the more you go to the northwest, the more likely you are to encounter Turkic or Tibetan horse thieves, and this is the legendary Grass Valley.

In fact, it is wanton looting.

If you want to say why foreigners can enter the hinterland of the Great Sui, it is very simple, because the frontier is large, and it is difficult to be found if there is really a small horse team coming in.

They don't rush deep into the hinterland of the Great Sui, especially in large cities, because they will be very troublesome when they encounter the defending Great Sui soldiers and horses, and they can't fight and fight, after all, the horse team has few people.

It's a pity not to fight, if they are supported by someone, it is not enough to waste time, and they are very good at pinching time, such as looting some materials to go back for the winter before the heavy snow closes the mountain.

Usually, the most robbed are the caravans coming and going to the Western Regions, especially some small caravans.

Usually they don't make a big move, and the Northwest soldiers and horses are not vegetarians.

Li De realized this, so the second half of the journey will make everyone be careful, in case they are targeted, foreign horse bandits are very dangerous, and the evil bandits and bandits in the mountains should not be underestimated.

Especially when it comes to the realm of poor mountains and bad waters.

"Li De, do you want me to send someone to the surrounding area to investigate." Lord Yu came over with a hu cake and asked.

The Jade County Lord has experience in battle formations, and it is a habit to send people to explore the surroundings, and it is generally scouts who do these things.

Li De's convoy transported all the food and salary of the soldiers and horses in the northwest, why didn't he use batch transportation, thinking that Li De was a businessman after all, and he wanted to control the cost.

High risk and high reward, so he chooses to take risks.

Lord Yujun's caution made Li De feel very good, and it was right to have a sense of precaution.

"Yes, try not to be discovered, just search around, I think the person you brought has such a ability." Li Dedao.

The Jade County Lord nodded, scouts sound very ordinary, but in fact, the soldiers who can be scouts are veterans of a hundred battles, and they have the ability to detect and counter-investigate.

Patrolling around will tell if they are following them if they are following them, and they can also easily cover up the traces left by the caravan, even if someone is following, they can confuse the enemy.

But obviously, Li De also had an experienced reconnaissance master on his side, and when the Lord of Yujun sent people to act, Zhang Chuchen had just come back.

She did not follow the caravan, but only landed near the caravan to follow, and with the help of Dabai, Zhang Chuchen was able to monitor the movement of the entire caravan.

Li De glanced at the seemingly dusty and proud Dabai, who was really jealous and envious.
