Siheyuan: I am Jia Dongxu's cousin

Three hours later, Zhang Weiguo arrived at a small island by helicopter.

This small island originally belonged to a wealthy man from Hong Kong Island. By chance, it was bought by Zhang Weiguo for 600 million US dollars. Zhang Weiguo renamed it Flower Planting Island No. .

The main function of this island is to serve as a research and development center. The entire island is guarded by 500 retired veterans with real guns and ammunition. For greater safety, Zhang Weiguo also obtained several anti-aircraft guns from America.

"Boss, we're here." Meng Cheng woke up Zhang Weiguo who was resting with his eyes closed.

After getting off the helicopter, Zhang Weiguo came to a 6-story building, which was mainly populated by people engaged in materials research.

Five minutes later, Zhang Weiguo took the Kevlar fiber, touched it for a while, and asked, "Have you done the test?"

A Chinese scientist replied: "Boss, we have tested it. If we only use Kevlar fiber to make bulletproof vests, it can protect against 9mm bullets at most. If we fill it with steel plates, it can protect against 7.62mm rifle bullets at most."

"But the weight of the bulletproof vest will be very heavy. My suggestion is to use Kevlar fiber and fill it with the special alloy we have just developed. Although this will increase the cost, it can ensure the weight while also protecting against 7.62mm rifle bullets."

After listening to the report of the Chinese scientist, Zhang Weiguo asked again: "What is the cost of using special metals?"

The Chinese scientist thought for a moment and replied, "Boss, if it's produced in the laboratory, it's about $50 per piece. If it's mass-produced in a factory, maybe $30 would be enough."

"30 dollars?" Zhang Weiguo thought about it and felt it was acceptable. Then he said, "Take me to the test site to see the effect of the bulletproof vest first."

"Okay, boss."

After a few minutes, several people arrived at the test site for testing the quality of bulletproof vests.

A security guard quickly stepped forward and put two bulletproof vests on the experimental scarecrow.

"Boss, everything is ready." A security guard reported.

"Well, let's get started."

After hearing Zhang Weiguo's words, three security guards shot at the scarecrow wearing a bulletproof vest from 3 meters away with a 9mm pistol and a 7.62mm rifle respectively.

After a few gunshots, Zhang Weiguo and his companions came to the scarecrow and saw that the scarecrow shot by the 9mm rifle was not seriously injured, but the scarecrow shot by the 7.62mm rifle had a bullet hole on its body.

After a while, several people returned to the safe area, and Zhang Weiguo asked the security personnel to wear special metal bulletproof gear.

"Bang bang..." After a few more gunshots, Zhang Weiguo discovered that the scarecrow hit by the 7.62mm was not seriously injured.

"That's right. Meng Cheng will give a bonus to those who participated in the research and development."

"Got it, boss."

After learning about the properties of Kevlar fiber material, Zhang Weiguo took a helicopter back to Hong Kong Island again.

The next day, Zhang Weiguo drove to Xinhua News Agency with a box.

Lin Liang was a little surprised when listening to his men's reports. Shouldn't Zhang Weiguo be busy with the arcade business during this period? How could he have time to open his own place?

But he still ordered his men: "Go and invite Zhang Sheng in quickly."

As soon as Zhang Weiguo came in, he said directly: "President Lin, I brought you a treasure this time."

"Well, baby?" Lin Liang was a little confused and asked directly, "Could it be that Zhang Sheng has come up with something good like an arcade machine again?"

"Hahaha, President Lin, you guessed right, but this time it's not an arcade machine."

Zhang Weiguo said as he placed the box in his hand on Lin Liang's desk and unlocked it.

Lin Liang looked at the things inside and was a little confused. Isn't this a bulletproof vest?

Lin Liang also participated in the anti-Fuso war and had seen the Fuso people's bulletproof vests.

"Mr. Zhang, isn't this a bulletproof vest? Do you still make this?"

At this time, Lin Liang thought that Zhang Weiguo was here to sell him bulletproof vests, but unfortunately, this thing was of little use against rifles, and the country did not have any extra money to buy this kind of equipment.

Zhang Weiguo looked at Lin Liang's expression and knew that he must have mistaken this for the bulletproof vests that the Japanese wore. He explained, "President Lin, this is not an ordinary bulletproof vest. It can protect against up to 7.62mm rifle bullets."

"7.62mm rifle bullets, Zhang Sheng, are you sure you are not kidding?" Lin Liang took the bulletproof vest handed over by Zhang Weiguo with a look of "you're kidding me".

Zhang Weiguo smiled and said, "President Lin, I seem to be joking with you. Why don't you find someone to try it later and find out?"

"This..." Lin Liang was a little moved after hearing what Zhang Weiguo said. If this dress is really like what Zhang Weiguo said, then...

Just as Lin Liang was thinking about something better, Zhang Weiguo said, "President Lin, please ask our military if they need this kind of equipment."

"Don't worry, the price is absolutely favorable."

Hearing Zhang Weiguo's words, Lin Liang smiled bitterly and said, "Mr. Zhang may not know, we..."

Just as Lin Liang was about to complain, Zhang Weiguo interrupted him and said, "President Lin, don't worry. I know the difficulties the country is facing now. I don't need cash. I can just use sand and stones to pay for it."

Seeing that Zhang Weiguo had said so much, Lin Liang could only smile bitterly and said, "Don't worry, Mr. Zhang, I will help you pass the things to the military personnel. As for whether the other party will accept it or not, I can't guarantee it."

"Thank you, President Lin, but I believe the military will not refuse."

Looking at Zhang Weiguo's confident expression, Lin Liang didn't know what to say, and asked, "Mr. Zhang, how much do you plan to sell it for?"

"35 dollars, please!"

Zhang Weiguo had someone calculate before, and it turned out that the cost of a bulletproof vest would be between 30 and 35 US dollars if it was mass-produced. It can be said that Zhang Weiguo did not make money directly from the country.

But after all, domestic sand and stone resources are indeed cheap. Generally speaking, with the prosperity of Hong Kong real estate, Zhang Weiguo does make some money.
