Yuan Rui didn't know if the down vests made urgently worked from beginning to end, he didn't ask, of course, he didn't have a way to get the court.

What he didn't know was that both Li Yan and King Huai mentioned one thing in the post-war performance, that is, the wartime vest provided by the Ministry of Industry played a very good role this time.

Cold protection is secondary, the down vest is lightweight and can be covered with armor without any inconvenience.

Generally, the bow and arrow shoot over, penetrate the armor and meet the down vest, which is equivalent to adding another layer of protection, and the effect is very obvious.

In fact, this was specially arranged by Yuan Rui, he knew that soldiers and ordinary people are different, not only to keep warm but also to protect the vital points.

So, he sewed the down with silk to make the inner liner, and then sewed the outer garment, which was ugly but much stronger.

After the war, it was concluded that the injuries of officers and soldiers wearing vests from bows and arrows could be reduced by more than half, and the direct lethality was also greatly reduced.

King Huai was also surprised at first when he saw this thing, he hadn't seen it before at all, so he specially ordered to bring a few pieces over for experiments.

At a distance of 100 paces, there is not much difference between vests and vests, and at a distance of 200 paces, vests block more than half, and most of the officers and soldiers do not die directly.

And more than 300 steps, plus armor, the bow and arrow penetrate the vest very shallowly, and the damage to the human body is not even a slight injury.

At this time, he and Li Yan were both surprised, the frostbite of the officers and soldiers plus the reduction of defense, if all the officers and soldiers were fully equipped, it would never be as many times as before to defend the thorns.

The reduction in non-combatants means that the pressure on the entire combat readiness and logistics will be reduced, and the economy of the court will not become so tight.

The two immediately played, and at the same time suggested that the Ministry of Industry should be rewarded, they hoped that the entire border army, including the northern border armies of Yulin, Wuwei and Youzhou, would be equipped with this wartime vest.

Next, the Ministry of Industry conducted a number of experiments and researches to improve on the basis of this vest.

The Lu family and the Sun family not only received praise from the court, but also became a special supplier of armaments for the entire border army, requiring that all the 500,000 border troops in the north be equipped with such vests in the next year.

Of course, not all of them do it, the Ministry of Industry itself also has a lot of workshops, and they are constantly rushing to work, but some raw materials have to be bought from Yangzhou.

Yuan Rui and the Yuan family are not included in this court's praise list, the vest is dedicated by the Sun family and made by the Lu family, Yuan Rui can make a profit as a shareholder, but there is no reward, and for Yuan Rui, it is also a good thing to be unknown.

Afterwards, the second son came a few times and didn't say anything, and even the Sun family sent someone to show his attitude.

In the past, the Sun family really didn't fancy this business, it was just a simple piece of clothing, and the benefits were even more pitiful.

But they didn't expect that it would have such a big impact when used in the military, whether it was fame or interests, the Sun family made a lot of money.

To say that the Sun family can also monopolize this business, it is a simple process, and there is no property rights.

But when the Sun family didn't have this awareness, it seemed that they knew something in advance, in order to prevent this from happening, Xu Lian, the waiter of the Ministry of Works, specially asked his second son Xu Yiping to go to Songjiang, a letter, two instructions.

No matter if this vest was come up with by the Lu family or whom, no rules can be moved. You might as well give a little more to the benefits that can be made, don't care about this money, and the cooperation can go a little deeper.

After reading the letter, Sun Siyang, the head of the Sun family, didn't speak for a long time, thought about it for a while, and burned the letter directly.

It didn't take long for the old man of the Sun family to make a special trip to Tonghai and meet with the old man and the second son of the Lu family.

The second son did not hide anything, he explained the origin and disposition of the wartime vest, and at the same time said some of Yuan Rui's thinking, in order to show that this was not a mess, he also said some things at the scene of the bandits.

Sun Siyang was even more curious, he couldn't figure out how a nerd who didn't go out knew so much, and he was an all-round talent.

Thinking about Xu Shilang's handwritten letter again, he finally understood, and sighed, this son's future is limitless!

The next day, the two old men who couldn't wait came to Jijiazhuang under the guidance of the second son.

When they arrived at Jijiazhuang, although the old man of the Sun family was mentally prepared, he was still surprised!

Master Sun was fooled by Yuan Rui this time, Yuan Rui really didn't think about using these military equipment to make money, the original idea was to let the border army win the battle.

In such a harsh environment, the soldiers are not well fed and clothed, and they have to fight hard with the flower thorn cavalry, how can they win!

Yuan Rui also said a few words of comfort to the two, military equipment is famous, let the court know, and the people also know that no matter what kind of business they do, as long as they open the opening, it is difficult to make money.

Like roast duck, this can be had, looking at the two foodies of the Lu family, it is not a good thing not to engage in an eighteen-state chain.

Besides, the seasonings of roast duck are also a business, not thirteen states, just to make eighteen spices, which is still called a thing.

There is also rice, if the double-cropping rice can be made, the grain harvested in Jiangnan alone is enough for the entire Great Xia to eat, with the grain, the body of the soldiers is strong, the soldiers are sufficient, and they are still worried about what thorns, these small countries are small in the south toe.

Of course, there are some things that Yuan Rui just said, but these simple businesses were said by Yuan Rui so wildly, and several people were stupid, can business still do this!

Is there anything more convincing than a little duck being made into a big business by him?

Old Man Sun didn't say much, and directly auctioned a silver ticket of one million taels, but at the same time, he also made it very clear that the amount of this silver ticket did not mean anything, it was the sincerity of the Sun family.

As long as Yuan Rui can see it, the Sun family will only account for 30% of the business in the future, and he will never interfere in business matters. made the old man Lu scold, but this old fox was cunning and took a big advantage.

Xu Shilang didn't expect that one of his letters would bring such a result, let alone that this letter would also leave a great opportunity for his future.

Yuan Rui doesn't want to get involved in any big business, a little land and a little money is enough, and if it is too much, it will become a disaster, even if he can keep it for the time being, as long as there is a loser among the descendants, it will be for dozens of generations to do it in vain, why spend so much energy!

However, it can't be completely ignored, there are more than 1,000 people in Jijiazhuang's own family surnamed Yuan, and they all eat from the fields, which is really hard.

Except for a few officials who have been officials, it is a little better, and many of them are a few acres of thin fields, and sometimes there is no way to do some casual work to barely survive, now that he has the opportunity, Yuan Rui thinks that he still has to do something to help them.

Since the down is already relatively mature, let's make another one and put it here in Jijiazhuang, so that the neighbors will have a little benefit, at least they won't be hungry.

Yuan Rui immediately thought of the sleeping bag, this is a good thing, the best in wartime.

Now the soldiers are at night, there is almost nothing to keep out the cold, there are no quilts, fur coats are only available to officials, ordinary soldiers are at most wrapped in some thick clothes overnight, think about it to know how difficult it is.

Yuan Rui thought of a simple approach, the outside is completely impermeable, impermeable to the kind of light water cloth, filled with down, at least in the general environment, so that the soldiers can have a small nest when they are resting.

In order to make the sleeping bag easy to carry, Yuan Rui made a small bag out of burlap, rolled up the down sleeping bag and placed it in it, and the soldiers carried it behind them when they marched, which was very light and thin, and would not increase the weight of the soldiers.

Yuan Rui is looking for two people who the Yuan family trusts more this time, the fifth uncle and the eldest brother Yuan Peng, and let them call the shots when they cooperate with the Sun family, of course, the Yuan family accounts for the majority of the business this time, and the Sun family's three percent remain unchanged, giving the Lu family two percent.

Yuan Rui also said that 20% of the Lu family was not given for free, and it would still be sold to the people in the future, and the Lu family could help whether it was transporting goods or selling them to other state capitals.

Then it's simple, the silver brought by the Sun family is enough, first dozens of acres of land were vacated in Jijiazhuang south near the Ji River, most of which are the kind of slopes that are not very good for growing rice, and it is useless to put them away.

Directly a row of houses, the very simple kind, was used as a workshop. Anyway, you don't need to live there often.

Yuan Rui took Xiaohe to try it slowly, did it several times, and found a lot of ladies with more exquisite handicrafts, and finally succeeded in making a complete sleeping bag a few days later.

Compared with the real sleeping bag, this is still a little simpler, the bottom is a slightly thicker linen cloth and water cloth, which is cushioned on the ground, no down, and a lot of silk is placed in the middle.

This is because the linen cloth is too heavy and the top is a simple outer water cloth with thick down, which is mainly used to keep out the cold.

There is also Yuan Rui who made the most daring attempt, he wanted to make leather sleeping bags, the kind that can be kept in the barracks!
