"I still have confidence in completing the tasks you have delivered. My writing skills should be OK, right?"

"The article is pretty good." Du Hei nodded first, and then taught a lesson earnestly, "But you have to be more down-to-earth. I have heard of your deeds, jumping up and down, fearing that the world will not be in chaos. Although Italians and society are generally impetuous, you will have to do big things in the future. You must learn to be restrained and calm. Of course, don't be as ignorant as me, so that you will still achieve nothing when you are old. I think it's good to learn your father's style. He is a dignified minister who personally stayed at the train station to solve the problem of train misses. This style is still very admirable."

"My father said I would learn more from you."

"Don't you need to put a high hat on me..." Du Hei changed his words, "Didn't you just say that you have any questions to ask me? Now you can tell me."

"That's right. After your book "Air Rights Reserved" was published, I think it was an epoch-making masterpiece comparable to "Theory of Sea Rights". I not only reviewed it in "Youth Daily", but also selected some chapters to publish it... But I think some of the content may not be fully explained... Of course, this company's current funding is relatively difficult, so the manuscript fee for the selected part is temporarily unable to be paid..."

"Repeat your words just now."

"I said that because of the difficulties in the newspaper's funding, the "Air Rights Reserved" selected part will not pay for the time being..."

"I'll ask the previous sentence."

"Oh, I say your work is comparable to Mr. Ma Han's "On the Sea Power", and it is epoch-making..."

"Who asked you this?" Du Hei shouted angrily, "What did you say just now and didn't explain it completely? What do you think of? I humbly accept it if you can tell the truth. If you can't tell the truth, you only know how to attract attention. Let's see how I teach you a lesson for your father!"

Antonio next to him laughed secretly: Your Excellency was surrounded by the young master again, this is really, really...

"I understand this way, right... The so-called independent air force basically refers to combat aircraft, especially bombers that can carry out bombing missions. Because their composition is different from other services and have very different commands, they need to form an independent air force instead of relying on the army and navy."

"Yes, that's what I said!"

"There are three small problems here: First, I think aircraft belong to the Air Force, but the Air Force does not only have aircraft; Second, bombers are very important, but it is very suspicious to only emphasize bombers and ignore fighters; Third, the Independent Air Force of course needs to cut with the Army and Navy, but it does not mean that the Army and Navy don't need aircraft..."

Du Hei was stunned for a moment, then slowly said: "These three are not small problems, they are big problems. You can tell me in detail that you are free today."

"The first big question, I wonder if you have ever heard of electromagnetic detection devices?"

"Electromagnetic detection device?" Du Hei was stunned, "What is it? Radio?"

"It is almost a kind of application of radio, but it is different from the radio I understand now. Radio waves can return." Contini explained. "Physicists tell us that radio waves encounter objects in the air, especially metal objects, will reflect them. This principle is used by using the ionosphere for broadcasting. Although it has not been popular yet, it has been confirmed by experiments that it is feasible. We have also popularized it in Youth Daily."

Du Hei nodded: "The popular science version of your newspaper is well done. I think it is more interesting and valuable than the literary version and the political version. It is a pioneering move among Italian newspapers. I have also ordered a copy to check it out."

"Thank you for your praise and support. I will bring this recognition back to the report agency." Contini continued after complimenting, "Since metal objects can reflect radio waves, if a device with sufficient power is made to allow him to actively emit radio waves in the air, if an aircraft flies by, the radio waves will be reflected due to obstacles, then you can know the general direction, position, speed, and height of the aircraft... If several devices work continuously and connect to each other, I can know the trajectory and direction of the aircraft group. If there are enough devices - such as all the borders are arranged, then I can know the dynamics of the enemy aircraft..."

This is the radar principle that only the Time Travel School can understand. Now it is said to Du Hei through Contini's mouth.

Du Hei's expression was very complicated. He fell into meditation for a while, frowned and analyzed for a while, and finally said: "Your idea is very interesting and challenging!"

"I wrote this idea in a letter and sent it to Mr. Marconi. He replied to me. He believed that it was possible in theory. He had to do an experiment to confirm the specific situation. Once a conclusion was reached, he would notify me immediately. If the discovery was of great significance, he would also write a paper about the discovery. However, the academic assumption was very clear - if the reflected radio wave energy of a stationary object was received and confirmed and the position was displayed, the radio wave reflection of the moving object could also be confirmed in theory, because the fastest object currently propagates insignificant relative to the electromagnetic waves and can be treated as stationary."

When Du Hei heard the other party mention Marconi, he became solemn: He not only knew Marconi's name but also knew him. The latter not only won the 1909 Nobel Prize, but also served for the Italian army during the war. Although Du Hei was the Army Marconi and the Navy, this name is not unfamiliar to him.

In his opinion, if Marconi really said this, it would probably be possible. Once this device was invented, the strategy and tactics of the Air Force would be greatly restricted. The so-called suddenness and concentration became a characteristic that was contrary to scientific development.

"So what you mean?"

"If this device exists, it will become a powerful weapon for the Air Force's combat defense. Just as the appearance of a tank has changed the infantry tactics, this radio device will definitely change the Air Force tactics and seriously weaken the overwhelming advantage of offense over defense. So I think this device, together with command, will become a core component of the Air Force; in addition, although anti-aircraft guns are artillery, I think they should also be the basic consideration of the Air Force."

"Anti-air gun?" Du Hei frowned, "You are talking about balloon guns, right? But this thing is useful for attacking balloons, and is used to deal with aircraft. IMHO, and there are almost no constructive results."

"This is just because the artillery development is not perfect enough. Uncle Du Hei, do you believe that in the future, there will be automatic loading, with a rate of fire per minute, and the caliber can be expanded to more than 100mm. If I combine dozens, hundreds or even thousands of anti-aircraft guns to protect the city or strategic points, can your bombing mission be easily completed?"

Du Hei was stunned, but he had to admit that what Contini said made sense. If thousands of anti-aircraft guns attacked together, the scene would be too spectacular.

"In addition to anti-aircraft guns, there is a third weapon. Do you remember the science fiction article published by Youth Daily last Wednesday."

“Which article?”

"The article about the Rockets by Mr. Robert Goddard, an American scholar."

In 1919, Robert Goddard, the father of the American rocket, published a paper titled "Methods to Achieve Great Altitudes", discussing the basic mathematical principles of rocket movement, and also proposed a plan to send rockets to the moon: "Making a rocket weighing 598.2 kilograms can send 0.9 kilograms of magnesium to the moon. The rocket ignites the magnesium when it hits the moon, and the bright flash of burning can last for a few seconds. You can see it on Earth with a telescope." This paper, which was later recognized as a classic work of space science, became a huge joke at that time. A newspaper laughed maliciously and said: "Modern Jules Verne invented the moon rocket."

But Contini knew that his idea was right, not only right, but the achievements of aerospace in the future far exceeded Goddard's idea. Unfortunately, this pioneer was not valued in the United States and was even repeatedly excluded. Contini planned to dig this gentleman to Italy when he had money. If he wanted to build rockets, yes! I paid for it! Build any rockets. The German, who was recognized by later generations as the authority of rockets, was still a 10-year-old elementary school student. In the future, he could only call him a senior respectfully when he saw Goddard.

"Rocket? I remembered..." Du Hei asked in confusion, "What is the relationship between the Rocket and the Bomber?"

"Don't underestimate the Rockets. I think the Rockets can become a brand new military weapon in the future. If they carry bombs, they can fly faster and farther than bombers without worrying about personnel safety; if they carry air defense weapons, they can pose a fatal threat to the aircraft... Do you think that future weapons with this function should be in the hands of the Air Force or be free from the air force?"
