During the voyage, Lin 2frog found that as long as he told the molecular structure of solar photovoltaic materials, they could also assemble them, and they could provide solar energy into electricity. As the distance from the target continued to grow, the big men became more excited, and they almost demanded full speed without stopping.

Even the big ones copied another engine and propeller, and the sailing speed was further improved.

This was a big surprise to Lin 2 frogs. After all, there are not only many internal parts in the more complex machinery such as the engine, but also the processing technology of each part, and the structural stress level of the parts caused by different processes is different. If you feel the same part, different processing methods will make parts with different properties in use. And the big ones can already analyze the internal structure of these internal metals by themselves.

Including the austenite structure inside the metal, it is a face-centered cubic octahedron to form a microscopic lamellar structure, which presents the ductile part of the metal in the metallographic microstructure, but does not have ferromagnetism. The austenite contains more other elements in the gap to form a variety of alloys, which will present different physical and chemical properties according to different elements, as well as stiffness, flexibility, ductility and so on.

However, it is such a complex microstructure, which has been imitated by the greats, and even surpassed. The output power of the second engine they copied was 70% of the efficiency of the original engine on the first day, close to 90% on the second day, and on the third day, the output efficiency was even increased by 10% compared to the original engine of the Lin 2frog and their combat vehicle!

Lin 2 frog was secretly frightened, could he have accidentally opened Pandora's box? They used to only imitate animal bones, but now they imitate metal, and it's a complex machine. Even more, they can already summarize their own experience in the internal microstructure and optimize it.

Even humans need to quench and temper steel to get the dronsy structure, and they can imitate it. However, the lamellar structure of the dross is even only 1 new meter, and the optical microscope cannot distinguish it at all. Only an electron microscope can be used. Lin 2 frog and Qingxue do not have the ability of electron microscopes. Therefore, what I showed to the big people before were some microscopic structures that could be seen under the optical microscope.

So it shows that at first they can see the big and big with a light microscope, but not their whole picture, and they can achieve a more microscopic scale of collaborative work.

Initially, they still needed Lin 2 frogs to give a schematic diagram of the microscopic structure, and then they arranged them into a schematic diagram, and then used Lin 2 frogs and their light microscope to observe and see where there was a problem. Now they don't need to. In just a few days, the microstructure has surpassed the control of the microstructure of basic materials!

At least if Lin 2 frog designs any machinery, the physical and chemical properties required for each component, as well as the stiffness and ductility, etc., can only be as close as possible to the demand in industrial production after calculation. However, because the factors such as production and processing are too complex, as well as economic factors and other factors, it is rare to fine-tune the internal structure to achieve the best working conditions.

But the big ones can. Even they can do on-the-fly fine-tuning!

By the 9th day of their departure voyage!

Lin 2 frog their original engine, the efficiency has also suddenly improved!

Qingxue and Lin 2 frogs both know that they must not only gather sand into a tower to construct matter, but also achieve physical and chemical properties through microstructure. They can also penetrate into the material that has already been formed to affect its microstructure.

Optical microscopes, on the other hand, can see bacteria, and most of them have reached the microstructure level of electron microscopes. However, Lin 2 frogs do not have the ability to observe with an electron microscope, so it is not good to judge which microstructure they have reached. But obviously, if it is smaller than bacteria, it is perfectly possible to invade their body.

Even the two of them recalled that when they first met Dada, Dada often emphasized repeatedly: "Don't look at you big, we are not afraid of you!" ”

Their words are very confident.

At least Qingxue can make up for it.,They infiltrate into their bodies on a tiny scale.,And then assemble a knife inside the body to hurt yourself.。。。 And at the moment they can assemble propellers!

Although Qingxue and Lin 2 Frog did not have any friction or contradiction with the big bosses, just knowing that they could clean themselves up, and they had nothing to do with them, this already made Lin 2 Frog and Qing Xue very frightened.

Qingxue even had a private conversation with Lin 2 Frog about this concern.

"Do you think our minds are still our own?" Qingxue asked worriedly.

Lin 2 frog said: "It should be, the composition of thoughts is very complex, do you remember quantum consciousness?" Ideas are generated from the quantum level, molecular level, proteins, neuronal cells, etc., a whole multi-level and multi-dimensional interactive ensemble. Even though they are smaller than bacteria and can easily enter our bodies, they can never easily interfere with our thoughts. ”

Qingxue wiped her cold sweat and said, "I know I'm still myself, which is a little more reassuring... But I still felt scared. ”

Lin 2 frog said: "I'm also scared. ”

Then a voice sounded in their ears, perhaps strictly in their inner ears, a loud voice, saying, "Don't be afraid, you are friends." We will not harm you. ”

Qingxue said a little annoyed: "You eavesdropped on our conversation? ”

"Huh? We said early on that we would be with you more so that you would not harm us. By the way, we have protected you. You yourself don't know a lot of bad things in your body, and trying to hurt you has been wiped out by us. Dada replied confidently.

Qingxue said, "Although I know that there will be a lot of bacteria entering my body all the time. But my body has its own immune system. They know what to do! ”

"Huh? Is it like this? Da Da said.

Lin 2 Frog quickly interrupted their conversation and began to discuss how to make better use of the current and wind direction to increase their speed.

Seeing that Lin 2 frog's expression was different, Qingxue said simply: "Can you please leave for a while, I have some words that I want to communicate with my partner alone." ”

"We don't know why you're angry, but okay. Let's leave for a while. Da Da said.

Soon, it seemed as if a puff of white ash floated away from both of them.
