Silk was first used for bulletproof in the early days of World War I, when a number of heavy pieces of silk were folded and sewn into cowhide and worn on the chest, which could resist the damage of conventional low-speed bullets other than anti-aircraft machine guns and machine gun bullets at a distance of 300 meters.

But the disadvantages are equally fatal, first of all, silk does not have the ability to resist blades and fragments, and the damage of artillery fragments is often greater than that of bullets.

Secondly, the price of many pieces of high-quality silk is more expensive than the weapons in the hands of soldiers, and what is worse is that silk is not resistant to corrosion, cannot be recycled for a long time, and cannot be hoarded for a long time.

Bailiyan Yixing rifle has done damage test, Yongxing rifle is still a very low muzzle velocity of large-caliber rifles, the traditional safe smokeless gunpowder provides less kinetic energy than modern gunpowder, 14.5 milli round head lead bullet 200 steps away hit five layers of high-quality thick silk, the breakdown probability is 40 percent, the projectile poured through the pork to a depth of one inch.

The breakdown rate of hitting seven layers of high-quality thick silk at the same distance is 25 percent, and the maximum depth of the projectile pouring through the pork is less than half an inch. The thickness is increased to 10 layers, and the breakdown rate is less than 10% outside 200 steps, but there is still significant damage to the surface of the pork, and the projectile can still break the ribs outside the body, but it is better than the expansion and rolling damage caused by the bullet entering the body.

In view of the fact that the effective accuracy of the smoothbore gun will not exceed 100 steps, if the gun is fired from 100 steps away and can hit the target, the thickness of ordinary silk that cannot be penetrated by low-speed large-caliber bullets is at least 16 layers or more. If it is a modern high-speed bullet or a large-caliber machine gun bullet, silk is not a carbon fiber of Kevra after all, and this thickness does not help at all.

In view of the complex environment of the current battlefield, it is easy to corrupt, and the price alone is really expensive, and it is more than enough to buy two lives. Moreover, it can only prevent the upper and the lower, cannot resist the stabbing of cold weapons, does not prevent corrosion and is not durable, and it is basically useless and has no practicability at all.

After the appearance of the golden silkworm, the results of repeated tests showed that the breakdown rate of five layers of high-quality thick silk 200 steps away was less than 10%. Thickened to 10 layers, the breakdown rate of 100 steps away is 15%, if you use two pieces of cowhide armor in the pressed place to seal the package, or insert manganese steel plates, the bulletproof effect at 100 to 50 meters will be better.

Of course, if you do not use safe smokeless gunpowder and switch to traditional black powder, the safety factor of the golden silkworm silk will be higher, and the material will be less, because the kinetic energy of the warhead provided by the gunpowder is weakened, and the muzzle velocity and pouring kinetic energy are lower. If only one layer of silkworm silk is used to defend against clusters of arrows, the effect will also be slightly better than that of traditional silk.

Due to its longer shelf life and greater corrosion resistance than traditional silk fabrics, Golden Silkworm Silk has potential military value.

Since the discovery of the golden silkworm, it was not until last year that the initial large-scale breeding was basically realized, and the annual output was not high. For the time being, it was only used in the Imperial Palace, and it was also sold in department stores, and the price was 26 pieces of gold each, more than twice as much as the first-class brocade.

Of course, in fact, the cost is not much different from the traditional silk, the output of the golden silkworm silk is larger, and the processability is even better than the traditional silk, and the cost of large-scale breeding and production of textiles in the future should be slightly lower than that of traditional silk, selling at such a high price, which is not only the cash of product quality and scarcity, but also provides funds for the future strategic reserve of golden silkworm fabrics.

A large number of hoarding strategic materials must always have special funds for collection and storage, and the difference in the price of selling at a high price will eventually be used for the reserve of golden silkworm fabrics.

Mooney wants to buy golden silkworm fabric, Bailiyan doesn't think he can use it for special military purposes, after all, traditional silk already has the ability to resist arrows, and it is really not possible to put two layers of silk in addition to the work.

What puzzled Bailiyan was why Mooney had to ask for golden silkworm fabrics by name, after all, such a high price was not worth spending money on at all.

That night, in the Liang State Legation's Mansion, Ji Feng did not persuade King Xian to let go, but on the contrary, Li Yi brought a message from Bailiyan, which made him very unhappy:

"That's what he said!"

"That's what I said, uncle." Li Yi said truthfully, in fact, he still concealed a lot of sensitive content in private.

Ji Feng thought for a moment, and then said:

"Why didn't you see that this guy would be a deep pool of hidden dragons, what a mistake......"

"Uncle, uncle has no intention of backing down, what should we do?"

"What else can be done, if you can't persuade Xianguo to advance and retreat together, Bailiyan will go down the price of silk cloth and cotton cloth together, and my country's loss will not be two million inches of silver, but one and a half million yuan. It's a windfall. Back then, the barbarians in Xianguo paid countless compensations, and this time they got a huge amount of business, which is really infuriating. ”

"But that's what my uncle bought with his life."

Li Yi argued, and Ji Feng scoffed:

"The Central Plains has been in war for decades, and there are still few people who have died, just Xianguo deserves the millions of huge money, and everyone else deserves to die in vain."

"But that's not the same. It's good that my uncle fought in the south and the north for the Central Plains, and if my uncle hadn't been in danger alone, Jin Xuedi would have hit the door long ago. ”

"Bastard, there is no one in the huge world in my Central Plains! Without him Baili Yan, I still have Shangguan Yan, Zhuge Yan, and Sima Yan in the Central Plains...... Whoever said that it must be him, Baili Yan can repel the barbarians. ”

"Uncle must say so, and my nephew has nothing to say. However, my uncle never said the same, he said that if he can't do business, there must be other ways. Uncle, you have to be careful. ”

"Why, you're still speaking for him!" Ji Feng asked unhappily.

"No, it's my uncle's prestige, I heard that there is nothing in the world that my uncle can't do, if he really wants to say that he won't be allowed to do this business, it must be true."

"Then tell me, what conditions can make Bailiyan compromise?" Ji Feng asked, not actually reporting any hope in his heart.

"I don't care about this, but when my uncle asked, I will say a few words. According to me, my uncle is not greedy, even if he suffers a little loss on the surface and makes up for it secretly, but if he is given a knife inside and out, my uncle will definitely give us a sword with his backhand. ”

"It's easy for you to say it, make up for him secretly at a loss, how do you let Uncle make it up."

"That's your business, I can't control these things, and I can't bear it."

"What,, you really think millions of gold and silver are!"

Ji Feng's face became even more unhappy when he heard the fire, Li Yi's face was as it should be, and he yawned again and again:

"Ah...... It's not early, why hasn't my cousin come back, it won't be that he was dragged to a brothel by Yin Yangjun. Uncle, it's nothing, I'm going to sleep. ”

"Let's go, let's go, let's go."

Ji Feng waved his hand again and again, looking depressed and angry.

When he was young, he didn't wait for Li Yi to go away, and the soldiers outside the house came to report:

"Qiyu Boyuanjun, the young marquis has returned home."

"Oh, please come here."

"No!"

After a while, Ji Kang was late, full of alcohol:

"Nephew, how much alcohol have you drunk?"

Ji Kang was drunk and unsteady on his feet, and his face was red and swollen:

"Hi...... I didn't drink much, but I drank less than half a catty. ”

Ji Kang staggered and fell on the seat collapse, drooping his eyelids listlessly. Ji Feng hurriedly asked again:

"I said nephew, where did Uncle Yin Yangjun say?"

Fang ...... Uh......" Ji Kang burped and continued: "Uncle Fang has already agreed to our conditions, but he also wants us to wait for them to promise them a condition in exchange. The nephew felt that he had to discuss with the third uncle, so he did not rush to agree. I wanted to find out what the Fang family's father and son were planning, but I never wanted to be drunk by the two of them. ”

"Do you remember Uncle Fang's conditions?"

"Remember, Uncle Fang asked me Liang Guo to buy cotton, hemp silk and soybeans from Jin Kingdom."

"Shhh...... This is thousands of miles away, and the cotton, hemp silk, and soybeans of the Jin Kingdom have to travel 15,600 miles by water, and Uncle Fang is stupid. ”

"Uncle Fang said that the Jin State ordered 20 Wanshi merchant ships from Xianguo in one breath more than two years ago, and they will be launched one after another in the following year, specially used for ocean cargo, and there will be more Wanshi ships in the future, and they will transport cotton, hemp silk, and soybeans to Liang State, and Liang State will transport the goods from the West Sea to Jin State, and the two ends will run a large amount of goods."

"Oh...... I see, how can I forget about it. ”

"Third uncle, my nephew is thinking about the rich products of the Jin Kingdom, and it should not be difficult to bring in some goods from the Jin Kingdom, it is better than the Wei Kingdom alone."

"Having said that, it is better to transport goods from the Jin Kingdom, and it is better to transport them from the Zhiguo to the inland rivers. Why go for the near and far? Taking a step back, the share of the Jin State was given, and the share of the Kingdom was given to the Wei Guo, what should the Wei Guo do if he turned his face. Or maybe the Jin Kingdom just wants to defend the country and turn his face to me, so that I can ask the Xianguo for help. ”

"This ...... It's not easy to say, it is said that Uncle Fang is Xihuan's uncle, Xianguo and Wei Guo are at war, although Xianguo will not be defeated, but it may not be beneficial to Xihuan. ”

"But it's good for the Jin Kingdom. Don't forget, nephew, although Uncle Fang is now said to have his hands and eyes open to the sky, but he relies on the wealth of the Xian Kingdom, and the wealth of the Jin Kingdom is still under the control of the King of Jin, if Uncle Fang is greedy, most of them will be used by the King of Jin. ”

"So, the king of Jin wants to push the Xianguo and defend the country to fight?"

"No, it's stupid. At present, the biggest beneficiary is none other than the eldest grandson, compared to the eldest grandson, the Xianguo is the strongest, and the defense of the country will never easily provoke the Xianguo in a short period of time, so he can only attack the eldest grandson. The king of Jin should have wanted to push Weiguo to fight with the eldest grandson, but the eldest grandson was defeated by Weiguo, so he asked Jin and Xian for help, and Jin urged Xian to go out to war with Weiguo, thereby weakening the national strength of Xian. ”

"Isn't that a mess?"

Ji Kang said incredulously, but Ji Feng sneered:

"Hehe, people die for money, birds die for food, the princes calculate and calculate, and they want to calculate us, which is really sinister. Nephew, go to sleep first, let me think about this matter for a long time. ”

"Okay, I'll rest first......"

The servant helped Ji Kang to stagger away, Ji Feng closed the door of the bedroom, sat in front of the desk with a candle and thought for a long time, and suddenly thought:

"No, it looks weird. Wei Guo's loss this time must be decided, Jin Guo is so sinister and shrewd, can't you see it? ”

Ji Feng suddenly found that Bai Liyan had no substantive action in the sword light and sword shadow, which was completely inconsistent with his consistent style of acting.
