"Don't underestimate this spider silk, in terms of mechanical strength, spider silk fiber is similar to Kevlar, which is currently widely used in the world to make bulletproof helmets and bulletproof vests, but in terms of toughness, spider silk is significantly better than Kevlar."

After Lao Zhangtou put down the transparent plastic box containing the spider in his hand, he clicked on a picture on the computer desktop and explained to Luo Hao: "Especially the spider silk spit out by this black widow spider is stronger than any spider silk known now. The black widow spider can spit out two different types of silk to weave into a spider web, the first silk, before being pulled off, can extend twenty-seven percent, and it is twice as strong as other spider silk; The second type of yarn has a high breaking strength, which is even stronger than Kevlar! ”

Under Lao Zhangtou's explanation, Luo Hao has a new understanding of spider silk, a material with broad prospects in the fields of national defense, military, and construction, including artificial genetic spider silk that is extracted from goat milk and cow after the spider gene is implanted into goats and cows, and is called "biosteel"!

"The country's research on the use of spider silk in the military field has never been interrupted, but it is not easy to turn ideas into reality!"

Lao Zhangtou sighed, and then with a hint of relief in his tone, he said: "But with this ninja suit you brought back, we have a research object, which is definitely a great help for our future research." ”

"Now, according to our research, this ninja suit is made of artificial genetic spider silk as the main material, combined with DuPont's CORDURA; And the wire you just saw under the microscope is, according to my guess, an alloy that we don't know at the moment. What we are doing now is to thoroughly study the molecular structure of this alloy and analyze it, if we can mass produce the composite fabric of the ninja suit, we can raise the level of body armor in our country to a new height! Luo boy, in the future, you may only need a camouflage uniform and tactical vest made of this composite fabric, which can resist the shooting of large-caliber anti-materiel sniper rifle bullets below and other calibers, greatly improving your survival rate on the battlefield! ”

At this time, the old chapter head can be described as dancing with his eyebrows and dancing with his hands. Luo Hao didn't interrupt Lao Zhangtou and quietly left the laboratory.

For a scientific researcher like Lao Zhangtou, who forgets to sleep and eat for a research, and pays silently behind his back, Luo Hao has a kind of gratitude and respect from the bottom of his heart.

Luo Hao had just returned to the dragon's lair by car, and was about to take his teeth to the cooking class to find the money squad leader and get two pieces of secret braised pork to satisfy his hunger, when he saw Lin Xiaoyang sneaking out of the back door of the kitchen.

I haven't seen him for a while, and Luo Hao almost didn't recognize Lin Xiaoyang. I don't know if the camouflage uniform on his body hasn't been washed for a few days, and he can't see the original color clearly, and he can smell the sour smell coming from him from a meter or two; His beard had not been shaved for at least five or six days, and he had a dark layer on his chin and lips.

Fortunately, Lin Xiaoyang has an inch of haircut, otherwise with a messy chicken nest head with hair sticking to the hair, it will be no different from the beggar under the bridge on the road.

If Luo Hao wasn't familiar with Lin Xiaoyang's figure, he really wouldn't have recognized him with his appearance.

"I haven't seen you for a few days, where did you go, how did you get such a picture?" Luo Hao stepped forward with his teeth, patted Lin Xiaoyang behind him, and asked, "What are you doing in the kitchen?" ”

Lin Xiaoyang, who had been paying attention to the direction of the kitchen, was taken aback by Luo Hao's pat behind him, turned his head to Luo Hao and made a silent gesture, pulled Luo Hao to run to the open space in front of the villa in the back mountain, took a breath and complained to Luo Hao: "Do you know that people are scared to death?" ”

"And what were you doing sneakily up to just now?" Luo Hao asked without answering.

Lin Xiaoyang opened a bag he was carrying in his hand and took out a piece of beef that was frozen harder than a stone.

"Damn, why are you going to the kitchen to steal beef jerky?!" Seeing the piece of beef in Lin Xiaoyang's hand that was still bubbling with cold air, Luo Hao's face was full of surprise.

Lin Xiaoyang stuffed the beef into Luo Hao's hand, untied the backpack behind his back, and said, "Test my 'new toy'!" ”

"When we were in peacekeeping, which battle impressed you the most?" Lin Xiaoyang asked Luo Hao.

Luo Hao thought for a moment and said, "We were trapped in the ruins of a building that time. If we hadn't found two barrels of hidden gasoline in the building and broken out with fire, we would have been in suspense. ”

Lin Xiaoyang snapped his fingers at Luo Hao and said, "The power generated by that kind of gasoline combustion is quite considerable. There were exactly two barrels of gasoline hidden in the rubble of the building we were in at the time for us to use; But we can't be so lucky every time we have ready-made gasoline for us to use. So, at that time, I was thinking, if we could shrink napalm to the size of a grenade and make it easy to carry, we would have one more offensive throwing weapon! ”

"So the time you've been missing has been to study this incendiary grenade?" Luo Hao's eyes glowed and he stared at the backpack in Lin Xiaoyang's hand.

Lin Xiaoyang took out a cylindrical, silver-gray grenade with a red marking band and an appearance about the size of a smoke grenade from his backpack, and introduced: "This kind of incendiary grenade that I have improved has a total of three layers of structure, and the center is a time-delay fuse; Outside the time-delay fuse is a layer of high-energy black sogold explosives and improved thermite; The thermite is filled with gelatinous gasoline mixed with metallic calcium all the way to the outer shell. This grenade can not only be used to attack ground targets, but also has the function of attacking underwater targets because of the addition of metallic calcium! ”

Lin Xiaoyang motioned to Luo Hao to put the frozen beef in his hand on the open space twenty meters away, without any combustibles around, and then put on the incendiary grenade that he had improved, tied a thin wire to the safety pin ring, and detonated the incendiary grenade by manipulating the thin wire.

Boom!

Under the action of the shock wave generated by the explosion of the lightweight and high-energy black sorkin explosive, the incendiary grenade formed an incendiary ring with a radius of fifteen meters in the open space, and the frozen beef that was frozen to a hard point was quickly melted in this burning circle, and it didn't take long for a burst of beef to be roasted, and the smell of roasted meat emitted by it showed the high temperature of this incendiary ring.

Smelling this fragrance, the teeth and eyes standing beside Luo Hao turned green.

The incendiary ring lasted for about thirty seconds before it went out as the gasoline was depleted.
