The door of the courtyard house has been welded dead

"Dang~dang!"

Holding the titanium-aluminum alloy plug plate, Li Feng knocked it. Not to mention the sound, it was really nice and exuded the smell of money.

The domestic reserves of this stuff are enormous, but the refining process is very complicated. Compared with the annual output of hundreds of thousands of tons of alumina, the annual output of this stuff is only a pitiful few thousand tons.

And it was at the beginning, so low that it was pitifully low. What does low output mean? It means that the cost is very expensive, and all the energy is used in important places.

For example, in aviation, everyone knows that this stuff is lighter and harder than steel. Why isn't it used on tanks? It's because it's damn expensive.

The requirements for processing technology are also very high. The difficulty is much higher than that of steel materials. The simplest tool, the blade for cutting edges, was broken several times and more than ten were scrapped. The raw materials were provided by the Beijing Nonferrous Metals Research Institute.

According to the ratio provided by Ran Qilin, aluminum is also mixed into this thing. The result is the two pieces of bulletproof plate back panels in Li Feng's hands, which are both light and hard.

"Come and grab some ceramics, I'll try it myself~!"

All the data are only on paper. The actual effect still has to be tested with live ammunition in the shooting range. Compared with the previous ones, this thing is a high-end product. If we really talk about the confidentiality level, Li Feng estimates that it is no lower than submarine steel.

"The thickness can actually be reduced a bit. According to calculations, the weight can be reduced by about 10%. In addition...!"

Ran Qilin arranged for his students to take the plug board and send it to the ceramic workshop, and told Li Feng about his new idea.

"No, don't, don't say anything else. It doesn't matter if it's 10% lighter or 10% heavier. If you can bear the weight, you can wear it. If it's 10% lighter, you still can't wear it. But the effect is very important to me. We can't just follow the lowest standard here~!"

Li Feng shook his head, his mind was very clear. This thing was so expensive, who could use it? Even Old Zheng probably couldn't use it. It was quite good for the head to stay on the neck. At least, it could play a small role in some aspects.

"That's it for now. I've been interested in ceramics recently. At present, our blade heads are far from being strong or hard enough in terms of material. I think alumina can play an important role in this regard. Perhaps, blade heads in the future can be made of these~!"

Seeing that Li Feng no longer asked to reduce the weight of the bulletproof plate, Ran Qilin shrugged indifferently. Compared to Li Feng proposing a research direction, he preferred to choose a research direction himself~!

Li Feng blinked his eyes. What he noticed more about Ran Qilin's initiative to take on the research of ceramic knives was the change in the old gang's words.

"us?"

"Hiss, hey, your word is a little different from before. In the past, you would only use the words 'domestic' and 'we' to replace 'us'~!"

Scratching his chin with interest, Li Feng looked up and down at Ran Qilin, feeling very strange. He wanted to laugh but held it back.

"Really? I didn't notice that~!"

Subconsciously glancing at the first-class collective merit hanging on the wall of the laboratory, Ran Qilin felt a little flustered. Perhaps he himself was not even aware of these subconscious changes.

"You used the right word. You should use 'we'. Just look at our skin color. We are different races, cultures, languages, and even ways of thinking~!"

"The world is constantly changing, but the game will never end until one side is completely defeated, just like the Indians back then. Either they become gorillas in the zoo, or their civilization disappears!"

"We love peace and seek peaceful development, but deep down, others are colonizers and plunderers. This is a cultural difference. We cannot integrate into the group. They are good at disguising themselves behind masks, but deep down they discriminate against people of our skin color."

"After all, we are our own people. These two or three generations have suffered a little and been a little tired. I want us to return to the card table and have the qualifications to continue the game~!"

Li Feng was very happy about Ran Qilin's change of mind, and it was a rare opportunity for him to speak out his true feelings.

For several years, Ran Qiuye failed to change his father's mind, but this time, Li Feng saw these signs from Ran Qilin's words.

"Is this what we often say, that imperialism is determined to destroy us?"

Ran Qilin did not refute what Li Feng said. Perhaps because he had been abroad for so many years, he even understood white people better than Li Feng. "The amount of resources is always limited. They have more, we have less, we have more, they have less. Eight hundred million people have to survive. Before, we had little resources, or even nothing at all. Anyone could bully us~!"

"The law of the dark forest has never disappeared. The struggle in the future will be more intense and unscrupulous. There are many people like you who return to the country, but many people have seen through the essence of it earlier than you~!"

"The essence is competition, competition for living space~!"

Ran Qilin's cultural level is higher than Li Feng's. He actually knows the truth that Li Feng wants to tell him.

"Civilization must be passed on. At least it cannot be interrupted in our hands. Otherwise, we will be the sinners of history. Of course, if we lose, even history may be gone. This is why we must strive to develop science and technology and improve productivity~!"

"This is inseparable from scientists like you. We have no other choice. We have been bound by pigtails for so many years and have fallen far behind. An island country with a small language has developed to the point where it has become a universal language across the world. How many civilizations have disappeared during this period~!"

Once we take the wrong path, history has given the answer: the living space is limited, and the development of weapons is becoming more and more silent.

Genetic weapons, viral weapons, and nuclear weapons are no longer enough. They are conducting dangerous experiments in the microscopic world by any means necessary. Their goal is to develop an idea that can destroy a civilization silently.

The winner takes all and the loser becomes meat on the chopping board. This is the law of the Dark Forest, and skin color is the simplest and most convenient tool to distinguish between you and me.

Li Feng left the laboratory, but these words still had an effect.

Read the error-free version at 69shuba! 6=9+shu_ba is the first to publish this novel.

Before, Li Feng had no idea of ​​telling Ran Qilin these things. Some words have to be said at the right time and the right place to enlighten, or in other words, to wake up a person who is pretending to be asleep.

If it’s a little earlier or a little later, the effect may not be as appropriate as it is now.

When Ran Qilin subconsciously used the word "we", it proved that he had figured out something.

Ran Qilin, sitting alone in the laboratory, thought for a long time, staring blankly at the plaque of collective first-class merit hung by the students on the wall.

He knew that he was recognized because he took a step forward, but he didn't know that this step could allow this civilization to continue.

This is what their generation did. In the dark forest, they fought for a living space for future generations, exchanging space for time, and finally, found a solution to the problem.

Otherwise, like the Incas, Mayans, and Indians, without space to exchange for time, all that awaits them is extinction.

This is the significance of this collective first-class merit, and also the significance of his research.

There is always a difference between working passively and working actively. People with higher education don't see things as clearly as Li Feng. Ran Qilin even feels that Li Feng doesn't look like a high school student, nor like an ordinary person of this age.

Ordinary people cannot express such profound words, let alone high school students. One has to stand at a very high level and have a bird's eye view to consider issues in this regard.

Li Feng didn't know what Ran Qilin was thinking at the moment. He stood in front of Jiang Defu's office, listening to the soft words inside. He felt like his back teeth were about to ache.

The door of the office is closed, but people who make phone calls always raise their voices subconsciously. This is because in this day and age, communication requires shouting. Even in the age of mobile phones, our parents' generation still can't forget this habit.

"Crunch~!"

Standing outside the door and eavesdropping was not something Secretary Li should do. It was not fair and upright, so he chose to push the door open and go in.

The scene inside made Li Feng laugh. The burly Jiang Defu looked so cautious when he picked up the phone.

Just like a young wife... (End of this chapter)
