In order to obtain all kinds of military and civilian technology mastered by Donghui, all countries and families obviously made full preparations before coming.

Cheng Gong originally thought that it would take half an hour for these fifteen forces to come in, but in less than twenty minutes, all of them returned to the Golden House with their respective expert advisory groups.

When experts and professors from developed countries such as the United States, the Soviet Union, the United Kingdom, France, Germany, Italy, Switzerland, and Canada saw the giant LED LCD color display screen hanging on the golden wall in the east of the lobby, almost everyone rushed to the front of the screen like crazy people, and their eyes almost fell to the ground.

A professional is a professional!

At a glance, these senior experts and professors from various countries can see how many shocking "black technologies" are hidden in this LED LCD color display screen!

"It's definitely not what a tube circuit can do!"

"It's just another electron imaging technology! This is the great invention of Genesis! This is a great achievement for the benefit of all mankind! ”

"Cake sellers! Cake sellers! It's so thin! It's so clear! ...... who sells cakes"

"This is definitely a new type of electronic technology that has never been seen before! Definitely not a tube! This is a hundred times more advanced than the transistor invented by Lillianfeld, no! A thousand times! 10,000 times! This is a miracle of God, a gospel for all mankind! ”

"Genius conception! Genius design! The perfect classic! I have decided, I want to join the nationality of Donghui! ”

"God favors great England! God favors great England! That's what I want! That's what I want! ”

“……”

Looking at the crazy demeanor of these experts and professors, Hoover and Mrs. M couldn't help but secretly exchange a look. Each other can read a message from each other's eyes: Donghui's scientific and technological heritage is beyond their imagination!

At the same time, the representatives of the governments of the governments, who had entered the Golden Room with the same purpose as Hoover and Mrs. M., were secretly frowning, and some were booing.

These technologists who only know how to do scientific research are really simple-minded. If you do this, you are afraid of the next competition, Cheng Gong, a cunning little fox, is not sure how the lion will open his mouth.

However, seeing these experts and professors like this, Hoover, Mrs. M, Mitterrand, Andrea Gromyco, Ishihara Waner, Song Ziwen, Himmler and others couldn't help but secretly rejoice that this trip to Chongming Island was the right one. It is very likely that the collection will be far greater than they expected and imagined before they came.

On the golden dragon chair, Cheng Gong squinted with interest at the fascinated scientists and engineering experts in front of him, just like a predatory cheetah staring at its prey in the dark. If all the high-end scientific research talents in various countries can be exhausted, it can definitely delay the scientific and technological process and the upgrading of the industrial system in these countries!

Silently, Cheng Gong turned off the large LED screen.

"Let me take another look, let me take another look......" A small old man with white hair and white beard threw himself like a child under the large screen that became as golden as the wall, his face turned up, his hands were played, and he kept yelling, as if his beloved toy had suddenly been snatched away by an adult.

Seeing the appearance of this white-haired and fluffy old man clearly, Cheng Gong couldn't help but be happy.

Quack, isn't this Einstein!

"Hehe, Dr. Albert, this LED LCD display technology is not very mature now." Cheng Gong leaned forward slightly, and said with a smile: "However, I still have some experience in photon theory and the photoelectric effect, so we can sit down and discuss it together another day." ”

After finishing speaking, Cheng Gong didn't pay any attention to Einstein, the lovely old man, got up from the dragon chair, cleared his throat with a "cough" twice, and said loudly: "I told you before that all the members who are lucky enough to enter the first cabinet of Donghui will not be disappointed!" ”

As he spoke, Cheng Gong turned on the LED screen again and scrolled the display content to the overview of the 2020 aluminum-lithium alloy technology and process.

"This king knows that what everyone is most concerned about is actually dual-use technology." Cheng Gongban leaned sideways, pointed at the big screen with his right hand, and said proudly: "This new type of aluminum-lithium alloy that we ordered as the 2020 alloy can undoubtedly satisfy your thirst!"

Aluminum alloy is no stranger to everyone. In 1924, Germany once developed an aluminum alloy called "Skron", which only contains 0.1% lithium aluminum-zinc alloy, although its mechanical properties were slightly better at that time, including the prevailing dura aluminum, but the advantages were not obvious, so it was not widely valued.

However, the 2020 alloy we invented not only successfully increased the lithium content to 1.5%, but also further improved the industrial preparation process of aluminum alloy, and more importantly, our process makes the production cost of 2020 alloy lower than that of dura aluminum!

Alloy 2020 can be widely applied to the skin of the wings and horizontal tail of various aircraft, replacing the original Dura aluminum, thereby reducing the weight of the aircraft. 2020 alloy has a smaller specific gravity than dura aluminum, but has higher strength, and has better tensile strength, yield strength, elongation, elastic modulus, pressure characteristics and corrosion resistance than dura aluminum!

Our large transport aircraft and bombers made of 2020 alloy can reduce the weight by 14.6% compared to the original Dura aluminum, save 5.4% on fuel, reduce aircraft costs by 2.2%, and reduce the annual flight cost per aircraft by 2.3%. ”

In the crowd, every time Cheng Gong reported a number of corpses, a German dressed as a Junker nobleman shouted that it was impossible.

Cheng Gong didn't look at Ernst Sindo, the chief designer from the German Junker company, until he finished talking about the fourth data, and smiled confidently and proudly: "Mr. Ernst, in Donghui, nothing is impossible!" ”

Ernst Sindo took a deep breath, slowly calmed down, and then strode out of the crowd, walked to a position less than three meters away from Cheng Gong, stared at Cheng Gong with a rigorous attitude unique to Germans, and asked: "Dear Your Majesty, do you dare to swear to God that every data you just said is true!" ”

"Of course!" Cheng Gong did not refuse the German aviation expert, one of the best aircraft designers in the world today, and replied with a categorical nod: "This king can fully assure you that if the 2020 alloy is applied to the Ju52/3m, it will definitely become the best passenger aircraft in Europe!" ”

Ernst Sindo looked up at the miraculous color display in front of him, then nodded seriously and said solemnly: "I very much hope that Juncker can sincerely cooperate with your country!" ”

"This king also hopes!" Cheng Gong said proudly: "However, this kind of cooperation must be based on the fact that you Germany can get the most likely high-ranking position in the cabinet!" ”

Ernst Sindo covered his chest with his right palm, made a court salute to Cheng Gong of the European nobles, and then turned around and walked in front of Henry Welf and Heinrich Himmler, who was wearing glasses, and said with an extremely solemn expression: "2020 alloy must belong to Germany!" Please! ”
