Exchange system, what the hell?
Ye Chen was shocked, followed by a great joy.
After receiving the gift package, the system has not been moving. Ye Chen has been worried that the system will not work. Now the system is finally moving. Ye Chen can no longer look at the light brain, but touches the ring, the familiar blue The screen appears.
Although light brain is good, the system is fundamental. As long as the system can be used, there will be many good things.
In the upper left corner of the blue screen, there is a line [Contribution Value: 20], and the screen is centered with gold glittering [Exchange System].
20 contribution value, needless to say, must be generated by light brain. Ye Chen is a little speechless. How high the light brain is, only 20 points of contribution value, which is too stingy.
Looking at the glittering exchange system, Ye Chen was excited again, and a heart beat. When she received the prize last time, Ye Chen had seen the charm of this golden light. There must be good things.
I couldn't help it anymore, Ye Chen was a little bit on the redemption system and entered the exchange system. One by one long menu appeared. After Ye Chen watched it, he was panting and flushed with excitement.
"Have made it, made it big," Ye Chen yelled.
Last time, there were only five options in the gift package, and there were too many options in the exchange system: elementary materials science, elementary missile technology, elementary power technology, elementary aircraft, elementary information technology, elementary computer technology, elementary manufacturing technology ...
Ye Chen is most concerned about computer technology. After clicking it, he found that this is computer technology.
Computer, Ye Chen would be very interested if it was before, but Ye Chen, who has mastered the light-brain technology, is lacking in interest.
Wait, the computer is a junior computer, so is the light brain a higher level, will it be an intermediate computer? Probably. How did light brain appear in the gift bag? Ye Chen was curious.
Think about the scene when you received the gift pack that day. Except for the unknown level of nuclear technology, materials science, aircraft, and missile technology are all elementary technologies. The mid-level computer, the light brain, is really strange.
Regardless of him, Ye Chen is a good thing. Ye Chen, who can't figure it out, doesn't want to waste brain cells.
Ye Chen entered elementary materials science, and a beautiful and familiar video began to play. It was a picture of various manufacturing materials. I watched this video when I received the gift pack, and I saw again that Ye Chen was still very excited, because this material science includes superalloy materials and composite materials.
The "heart attack" of planes in our country lies in the problem of aero engines. There are many reasons for the delay of the flight, and one of the most important reasons is that the superalloy material cannot pass.
If Ye Chen masters the superalloy material, it will cure the heart disease of the aircraft. The benefits are unnecessary to say, just think about it and get excited.
Composite material, which is a new type of material, is extremely versatile. It can be said that it is used in all walks of life. However, because the manufacturing cost is high and the output is not large, it greatly restricts the development of the industry.
"If there is no more suitable, I will have to exchange materials technology if I have the chance." Ye Chen is very eager for materials technology.
If nothing else, let's talk about light brain. Ye Chen, the current material, is not satisfied. If he masters the material technology, the material of light brain will be upgraded by one or more grades, which will improve the performance of light brain.
Once again into the primary missile technology, the familiar picture is playing. A missile lightningly hits a super battleship that is much larger than the largest aircraft carrier in the United States. This battleship was broken into pieces and sunk into the ocean floor.
Although I watched it when I received the gift pack, I saw Ye Chen was still full of blood.
Although Ye Chen did not learn missiles, he knew how powerful the missiles were. Compared to the missiles that the world has today, the power was much greater.
The aircraft carrier is a giant at sea, the attack power is super strong, and the anti-attack power is equally good. The United States has used the retired "US" aircraft carrier to conduct anti-attack experiments. The United States dispatched aerial and maritime underwater, and also installed on the US aircraft carrier. It bombarded for 25 days. No. This was sunk.
Not long ago, our country drilled an aircraft carrier in the East China Sea. The final judgment was that it did not sink. Of course, we did not dispatch our lethal weapons, anti-ship ballistic missiles.
This shows how strong the aircraft carrier's anti-attack ability is.
The super battleship in the video can't afford even one missile, which shows how powerful this missile is.
"If our country has mastered this kind of missile technology, will American aircraft carriers dare to show their strength around us? Will the United States dare to make troubles around us?" Ye Chen's eyes were full of little stars.
The video played by the basic aircraft technology let Ye Chen's eyes shine. The aircraft in the video has a sci-fi style, flying very fast, being able to make a variety of flying attitudes, very flexible and amazing. What's more, you can hover in the air like a helicopter.
We have been saying, "The plane we are flying is either Boeing or Airbus. When can we get on our own plane?"
If Ye Chen masters this technology, it can improve the aviation level of our country by several steps, and our large aircraft will be in the sky.
Information technology, mainly electronic information technology, including satellites and networks, Ye Chen's eyes stared at the stars, if mastered, it will make our country's communication technology to a higher level.
Primary power technologies, including steam, electricity and nuclear power.
Nuclear technology, not only can be used as a weapon, but also the most amazing power technology we have now, it is only elementary. Ye Chen is curious. What is intermediate power and advanced power?
Finally entering the primary manufacturing technology, Ye Chen was so shocked that his chin fell off for a long time.
"Oh my God, I really have no eyes, and manufacturing technology is the real treasure!" Ye Chen couldn't help shouting.
From the beautiful video, you can see that various complex parts are processed.
No matter how good the design is, it must eventually be manufactured. If there is no corresponding processing level, no matter how good the design is, it just stays on paper. Therefore, manufacturing and processing are the foundation of industry, and all countries are investing a lot of money to develop them. However, there are still some problems in the processing of complex parts such as impellers, blades, marine propellers, heavy generator rotors, steam turbine rotors, and large diesel engine crankshafts. Small difficulties.
In order to solve the processing problems of these complex parts, high-precision machining centers have been developed. Even so, it may not meet the requirements.
From this exquisite video, it can be seen that the complex parts that test the industrial strength of impellers, blades, marine propellers, heavy generator rotors, steam turbine rotors, and large diesel engine crankshafts are not a thing at all. How to process.
Think about it, if our country has mastered such manufacturing technology, our country's industrial level will jump a few steps, and even lead the development direction of the entire manufacturing industry, how wonderful it is.
"There is nothing to think about. The first thing to get is the manufacturing and processing technology." Ye Chen is very knowledgeable and knows how important this processing technology is to our country.
"MD, play with me." Ye Chen swore at the exchange of the required contribution value.
It doesn't need much contribution value, it only needs 5 million.
Ye Chen built a light brain to only contribute 20, that is, Ye Chen needs to build 250,000 light brains in order to save 5 million contributions. Ye Chen spent almost 20 days to build this photo brain. 250000 20 = 5000000 days. Converted into years, it is 13698. This is not more than 10,000 days, but more than 10,000 years. Can it be enough?
This is too expensive. Is there always a cheap one? Ye Chen swept one by one, only to find that the lowest requires a million contribution value, and the most expensive is manufacturing technology.
Ye Chen withered completely and kept saying, "Is this going to make a contribution?"
"Does the host spend 20 contributors to ask questions?" The mechanical sound of the system sounded.
"What, you can ask questions?" Ye Chen's eyes lit up sharply.
"Yes," the system answered.
Although the contribution value is difficult to make, as long as a way is found, there is always hope, and disappointed Ye Chen is full of hope.
