Chapter 1663 Experience Brought by Blood (Third Update, Please Subscribe)
The crying in the waiting hall was very harsh.

Hearing the crying sound, Li Yixuan just turned his head and then walked towards the hall. After a few steps, he saw someone taking pictures of him.

It's the paparazzi.

What is the biggest problem after your identity is exposed?
There are more paparazzi around him - there are always reporters following him, and perhaps the censors will ban some political news from appearing in the newspapers, but for him... there is no special care.

Moreover, the outside world was very curious about him, so he was the darling of newspapers for a long time.

Not only do SEA media like to report on him, but so do foreign media. After all, in some countries, he is called the "Crown Prince of the Empire."

Although the empire no longer exists, no one can ignore what he will inherit in the future - in addition to SEA, there is also unimaginable wealth.

However, Li Yixuan has now become accustomed to being paid attention to like this. He puts on sunglasses and then ignores those people.

In fact, he could even pretend not to know him, because he had an ID card - George Albert, which was the name his mother gave him in memory of his grandfather, George VI.

In fact, his English name is George, and even now Aunt Elizabeth and others still call him George.

“Maybe, I can try it next time.”

Half an hour later, as the plane flew towards Taiping, Li Yixuan, who was in the first-class cabin, flipped through the information in his hand. It only took more than an hour to get from Changan to Taiping. When the plane was about to land, the flight attendant walked to his side, squatted down, and whispered:

"My dear, the plane will land soon. The airport has arranged a VIP channel."

Privileges always exist.

Even though Li Yian is against privilege and Li Yixuan has no sense of privilege, you cannot deny that all this does not exist.

In fact, it is normal for Li Yixuan to use the VIP channel because both the airport and the airline are "family businesses."

After leaving through the VIP channel, Li Yixuan went straight to the destination of his trip - KTJ Laboratory.

As soon as the car stopped in front of the laboratory, the head of the laboratory hurriedly opened the door and said respectfully:

"Young Master, welcome!"

This is also a subsidiary of the company.

Li Yixuan nodded and said:

"Is everything ready?"

"Already prepared."

Soon, the group entered the laboratory, where Li Yixuan met Zhao Youguang, the inventor of Kevlar fiber.

"Dr. Zhao, can you introduce this fiber?"

"OK,"

Zhao Youguang said:
"As you probably know, this synthetic fiber is a high-strength fiber we introduced a few years ago. Its chemical name is poly(p-phenylene terephthalamide), a very strong aramid fiber. The fiber properties of Kevlar make it both soft and heat-resistant, while also resistant to corrosion by various acids and chemicals. Surprisingly, when these fibers are woven together, their strength actually exceeds that of steel!"

In the product center of the laboratory, Zhao Youguang pointed to the product and introduced it:
"Initially, this super fiber was only used for tire cords of super sports cars. Most of the tires used by our automobile companies in car races use this special tire. Later, it was used to manufacture the shells of ballistic missiles. Now, the shell materials of some of our missile models are made of aramid fiber and epoxy resin. Sir, take a look at this."

Pointing to the epoxy resin board on display, Zhao Youguang said:
"This is our product, and its use has played a great role in improving the performance of missiles."

Li Yixuan looked at the sample and asked curiously:

"Oh? It's actually used on missiles."

What he didn't know was that it was thanks to the new shell material that the range of the "Carpenter" medium-range missile and submarine-launched missile was greatly improved. After the war, the shell material of the rapidly developing ballistic missiles had undergone two iterations of development. The first generation of shell materials was metal shells represented by high-strength alloy steel, and the second generation of shell materials was fiberglass/epoxy resin manufactured using a fiber winding process, which is also the mainstream in various countries today.

Only SEA used the third-generation shell material in advance, relying on Kevlar fiber.

However, what Li Yixuan was concerned about was not the shell material of the missile, but the nature of the material. He stared at the Kevlar epoxy resin board and asked:

"So, it's stronger than steel, but much lighter than steel?"

"Yes," Li Yixuan said after hearing Zhao Youguang's answer, looking at the sample that was four or five millimeters thick.
"Take a few samples."

Although they were a little puzzled, they still took the samples as he requested and weighed them in their hands. They were indeed very light. Then, Li Yixuan went to the yard, stood in front of a tree, thought for a while, and fixed the three samples to the tree with ropes.

Amid people's doubts, Li Yixuan shouted:
"Captain Wang, give me your gun."

After his identity was exposed, the Secret Service assigned him a security agent, with Wang Mingkui as the person in charge.

Facing his request, Wang Mingkui did not hesitate and directly took out a pistol, which was a Kuski 65 pistol. This pistol was not a product of Nanyang Defense Equipment Company, but a weapon developed by a pair of Czech immigrant engineer brothers, Josef Kuski and František Kuski. The two brothers were designers of Karl Metal Company and they were the chief designers of the Czech National Arsenal CZ Company.

More than a decade ago, they immigrated to SEA with their families, and then joined Carl Metal Company to design this pistol with a large-capacity magazine and double-action trigger.

Two years ago, when this type of pistol was launched, it attracted attention from all parties. Although it does not have any particularly outstanding special design, it combines the advantages of many pistols in one, with comfortable feel, reliable performance, good accuracy, and first-class workmanship, so it is highly praised.

The Secret Service was one of the first agencies to adopt it, and the military is currently testing it. This pistol with a large blank round capacity is likely to be welcomed by all parties.

During the military operation in Java, Li Yixuan used a Kurski 65 pistol instead of a military-issued pistol, so he was very familiar with this gun.

After taking the gun and turning on the safety, Li Yixuan fired two shots at the target.

After the crisp sound of gunfire, Zhao Youguang stared at the "target" on the tree and said excitedly:

"Sir, you mean, it can be used to make bulletproof vests, right?"

Not to mention Zhao Youguang's excitement, several senior executives of KTJ Company were also excited. After all, ever since the laboratory developed Kevlar fiber, they have been studying its uses.

From tire cords to missile casings, everything that can be thought of has been used, but the available quantity is still very limited. After all, the number of missiles is there.

But now, Li Yixuan's shooting changed everything.

"Bulletproof vest... Yeah, that should work too."

As Li Yixuan spoke, he walked to the tree, looked at the bullet marks on the sample plate, and said:

"I'm thinking of a bulletproof helmet. The military is still using the steel helmets from World War II. They can block shrapnel, but not bullets. When I was on the front line, some of my comrades were shot in the head and died, so..."

In the past few months, Li Yixuan has been thinking about his fallen comrades, and as he thought about it, he came up with how to protect them.

As for bulletproof vests, alumina bulletproof ceramic inserts are sufficient.

So, he was wearing a steel helmet - Zhao Minghao died because the bullet pierced the steel helmet.

Steel helmets. The steel helmets used by the military are basically the M1 helmets donated by the United States. This type of helmet performed relatively well during World War II.

But what about now?
In fact, World War II helmets are still being used almost all over the world.

However, Li Yixuan was not satisfied with the blood and lives shed by his comrades, which made him feel that he needed to care about this matter.
In the past few months, he has been thinking about how to design a better helmet. But this matter is obviously more complicated than he thought.

A helmet with better performance means a thicker steel plate, and a thicker steel plate means it is heavier.

The helmet is worn on the head, so the weight requirement is extremely strict.
Because of this, his idea basically fell through.

It was at this time that he learned from his brother that there was a type of fiber whose strength even exceeded that of steel, and that fiber had been used in car tires. Surprised, Li Yixuan immediately looked for information in this regard.

So this is how he came to visit the company.

And now these two shots have proved that his trip was worthwhile.

Walking to the tree and picking up a sample that was somewhat deformed by bullets, Li Yixuan nodded with satisfaction and said:
"Manager Sun, you can conduct research in this area and develop a helmet made of Kevlar fiber. I believe this helmet will definitely have a bright future,"

"Sir, please rest assured, I will arrange this matter right away."

Often, an unexpected whim will bring some unexpected life, just like now. Li Yixuan didn't know that his suggestion not only gave birth to the world's first non-metallic bulletproof helmet, but also pointed out a new direction for the development of bearing materials. His discovery will save countless lives in the future.
In order to achieve better bulletproof effect, they also developed composite bulletproof vests. The outer layer of this bulletproof vest is usually made of hard materials such as metal or ceramic, while the inner layer is a fiber protective layer. The combination of inside and outside can achieve a higher bulletproof effect.

For its discoverer, Li Yixuan, all he wanted was a helmet, a helmet that could protect the lives of his comrades.

In fact, many times, only those who have experienced war know what the soldiers on the battlefield need!
After all, this is experience gained with blood!
