. January 27, 3 p.m.

Shi Lei came to Li Chai's temporary R&D and manufacturing center, which is the Green Lake Building. Shi Lei wanted to know about the progress of the third generation of Dawners.

After obtaining the information of the Silver God of War and the recipe for Snow Silver metal from the Compass region, Shi Lei immediately passed it on to Li Chai through the guò neutrino network, asking Li Chai to study the possibility of using Snow Silver metal to make the Dawner.

"Brother Shi, you're here!" When Shi Lei came to the Green Lake Mansion, Li Chai happened to walk out and met Shi Lei.

Shi Lei was curious: "Little Lizi, where are you going?" ”

Li Chai was wearing a work suit, and he was holding a wrench in his hand, with a rhythm that wanted to knock people.

"Uh..." Li Chai hurriedly put down the wrench, and then said, "Brother Shi, I'm looking for inspiration!" ”

"Looking for inspiration?" Shi Lei looked at Li Guess strangely, "Little Lizi, what inspiration are you looking for?" By the way, the Snow Silver Metal recipe that was sent to you earlier, can it make the Dawner? ”

Asked about the questions related to machinery, Li Chai suddenly came to his senses, and said with a fluttering eyebrow: "Of course!" Not only can, but it's very suitable! Brother Shi, I have to say, where did you get such excellent memory metal materials? This kind of metal is a perfect match for the Dawner! ”

"Oh?" Shi Lei was puzzled, why is snow silver metal a perfect match for the dawner?

Li Chai turned around and led the way, walked into the R&D and manufacturing workshop, and instructed: "Yishuer, project all the information!" ”

"Okay, Mr. Lee." Li Chai set a calm middle-aged voice for Yi Zuer. Very much in line with the identity of a real yàn room assistant.

Yi Zuer immediately projected all the information into the LIP lens information processor of the two, and Li Chai explained the information.

"Brother Stone. Snow silver metal has a good hardness, according to the Mohs scale of hardness, snow silver metal actually reaches 9 degrees, which means that snow silver metal has the same hardness as sapphire. Except for a very small number of items, such as diamonds and moissanite, which surpass the snow silver metal in terms of hardness, the rest of the items. It is difficult to leave marks on the surface of snow silver metal. Li Chai excitedly introduced.

Shi Lei frowned, "That's not right! Little plum, that's not right! I remember. The Dawner's alloy heavy sword has left a very obvious scratch on the surface of the snow-silver metal! ”

In the previous time in the Compass region, the Dawner had faced Snow Silver several times. It is indeed on the surface of the snow silver metal. Very visible traces were left behind.

Li Chai laughed and said, "Brother Shi, do you know the material of the Dawner's alloy heavy sword?" ”

"I don't know." Shi Lei obviously didn't know.

"The Dawner's alloy heavy sword is made of a mixture of tungsten steel and chromium alloy, and the Mohs hardness is also as high as 9!" Li Chai said with a smile.

With the same hardness, the Dawner's alloy heavy sword can certainly leave traces on the surface of the snow silver metal!

Shi Lei coughed twice, hiding the fact that he was a mechanical novice. "Little plums, since the two have the same Mohs hardness. Why is Snow Silver a perfect match for the Dawner? ”

"Because snow silver metal is memory metal, and it also has special physical properties. Or to say the exact opposite. Li Chai said excitedly.

But Shi Lei was completely dazed, how could Shi Lei understand these things?

Li Chai hurriedly explained: "Brother Shi, let me give you an example, under normal circumstances, flames can't burn in water, right?" ”

Shi Lei nodded, under normal circumstances, this is indeed the case. Of course, there are some special cases where even in water can burn. For example, in the Five Rings Games in Austria, isn't there a scene of ignition in the water?

"Snow silver metal is the opposite of the opposite nature of a burning flame in water! Snow silver has a hardness of 9 on the Mohs scale, but it has the same ductility and toughness as metallic silver. Metallic silver has a hardness of only 2.5-3 on the Mohs scale, and it has very good ductility and toughness. This means that snow silver metal does not have the same hardness as sapphires, but it is very easy to break and has almost no resistance to bending. Li Chai explained a lot.

But Shi Lei still didn't seem to understand.

Li Chai patted his forehead, and he was convinced of Shi Lei, a mechanical novice, so he had to explain it with a more vivid example.

"Brother Shi, you know the sapphire, right? Forget it, let's not talk about sapphires, you definitely don't understand. Let's talk about glass, the Mohs hardness of conventional glass is between 6-6.5, and it is basically impossible for objects below this hardness to leave marks on the surface of the glass. However, glass is fragile, and we can smash glass even with ice cubes with a hardness of only 2-3 on the Mohs scale, right? Li Chai explained again.

Shi Lei understood this time that the hardness of glass exceeds that of ice, but ice can also smash glass. "What does that mean?"

Li Chai patiently explained, "We now imagine the snow silver metal as glass, and then use ice cubes to smash the snow silver metal. Although the power of the ice cube is enough to smash glass, the glass does not shatter, but suddenly changes its physical properties, as if by magic, and has a tenacity as soft as silver. At the same time, it also has the ability to restore memory metal. In other words, even if the Dawner's Metal Heavy Sword is hit by the enemy with a diamond diamond, the Metal Heavy Sword will not break, and it will automatically recover. ”

Shi Lei was slightly disappointed, Li Chai explained that it was only such a small role for such a long time?

Li Chai seemed to see Shi Lei's disappointment, and he continued: "Brother Shi, maybe you think that the role of snow silver metal is very small? What if we made the whole of the Dawners entirely of snow silver? Especially the shock absorber! Once Snow Silver metal is used for the shock absorber, there is no longer any problem of the Dawner's shock absorber breaking or being damaged. In other words, it's like in an online game, having equipment that never breaks down and never wears out. ”

"?" Shi Lei finally showed a look of surprise, "Xiao Lizi, you're not kidding?" ”

Li Chai shook his head, and then picked up a spring as thin as a hair from the workbench, "Brother Shi, this is the model I made using snow silver metal. ”

"What's the use of this?" Shi Lei was puzzled.

Li Chai grabbed the snow-silver metal spring as thin as a hair with both hands, although it was only as small as a hair, but because of its super high hardness, it would take a lot of effort to pull it apart.

"Brother Shi, you have a good look, sapphire, tungsten steel, and chromium alloy of the same hardness are absolutely impossible to have similar properties." Li Chai pulled the spring, the length of the spring has exceeded three times the original length, and when the spring gradually approached the limit, Li Chai still did not stop.

The hair-thin spring was stretched to six times its original length, and Li Chai laughed, "Brother Shi, do you see it?" The perfect combination of toughness and hardness, it was impossible to happen, but it happened right before our eyes! ”

Shi Lei is a mechanical novice and doesn't understand the meaning of this.

Li Chai continued to exert force with both hands, and suddenly pulled the spring as thin as a hair, changing the structure of the spring, until the spring was pulled into a thin line, and then stopped exerting force.

"Brother Shi, next, is the time to witness the miracle!" Li Chai picked up the thin thread as thin as a hair with one hand, and due to its super hardness, it did not soften like a hair, but stood straight upright.

If this snow silver wire is used as a weapon and pierced into the human body, it will definitely be no problem.

The snow silver wire in Li Chai 's hand slowly changed, from the original straight state, slowly bent, and a spiral shape appeared, and after a while, the snow silver wire became the original spring again.

Shi Lei was really shocked this time!

"How long did it take to restore it to its original shape?" Shi Lei asked the Guò LIP lens information processor.

"Sir, it's exactly sixty seconds. Li Chai has done many experiments, and the recovery time of snow silver metal is all sixty seconds. Yi Shuer responded to Shi Lei.

Even if Shi Lei is a mechanical novice, he now understands the value of snow silver metal.

As Li Chai said, the most basic application is to make cold weapons from snow silver metal, which can reach a permanently sharp state with no wear and tear and no lasting limitations.

If it is made into a kitchen knife, then whether it is a hundred years, two hundred years, or a thousand years, this kitchen knife will always be sharp. It doesn't matter if you use this kitchen knife to chop bones, or cut the floor. As long as it is not used to cut diamonds, causing damage and missing of the body, it is really a never-worn property.

However, the use of snow silver metal to make cold weapons is really the most basic application. Moreover, how can such an excellent material be used to make cold weapons on a large scale?

Shi Lei calmed down a little, patted Li Chai's arm, and praised: "Little Lizi, well done!" ”

Li Chai scratched his head, "Brother Shi, you still got a full set of information." Otherwise, I would not have been able to make such a miracle metal as Snow Silver. ”

"By the way, Xiao Lizi, all the parts of the entire Twilight can be made of snow silver metal, right?" Shi Lei asked.

If you have a Dawner made of snow silver metal, when you were in the Compass region before, the Dawners of Shi Lei, Ma Liang and Zheng Sanpao would not have been permanently damaged by the shock absorber.

At the same time, if the fourth-generation electromagnetic cannon and ruby laser cannon are also made of snow silver metal, then the No. 5 real body cannot pose a threat to them at all!

Li Chai nodded affirmatively, "Brother Shi, I have already made a preliminary design plan, and the third generation of the Dawner will definitely be made of snow silver metal." ”

"Little Lizi, I need an answer, if snow silver metal is used to make the Dawner, then what kind of performance does the Dawner have?" Shi Lei asked Li Chai.
