After Donald came in, he looked around the warehouse and found that there was nothing missing and he didn''t care too much. Then he put all the five tons of glass he bought into the warehouse, and then went out of the warehouse and walked to the nearby manufacturing workshop.

    Soon he came to the manufacturing workshop.

    When Donald walked into the manufacturing workshop, a smile finally appeared on his face.

    The manufacturing workshop of Donald''s base is very large, the size of several football fields. If there are unfamiliar technicians familiar with this era, you will find that many equipment in this manufacturing workshop can not be produced in his era.

    For example, Donald''s several square machine tools or machining centers in his workshop are, yes, machining centers. After all, in his era, it is impossible to produce machining centers, but there are machining centers in his manufacturing workshop.

    Although these processing centers in the manufacturing workshop, if there are knowledgeable people, will find that their technical level is not very high, at most it is equivalent to the level of ordinary processing centers in Wang Bin''s time. However, in Donald''s world, this is definitely the existence of proper black technology.

    At the same time, in addition to these machining centers, the planer, grinder and even metallurgical equipment in this workshop can not be produced in this era, because these equipment are CNC equipment.

    Yes, these equipment were purchased by Donald at a great cost from the technology mall. Take these CNC three-axis machining centers for example, the price of each machine tool is more than 500 energy coins.

    You know, this is not a high-precision machining center! If Wang Bin is present, he will be jealous of the price of these machine tools. After all, the precision level of these machine tools is only equivalent to the level of ordinary machine tools in Wang Bin''s world.

    Although all these equipment in the manufacturing workshop cost Donald more than 100000 energy coins, Donald doesn''t care. After all, only good equipment can make good equipment.

    Of course, Donald is certainly not the only one in such a large workshop. There are many people in the workshop at this time, and these people are busy next to these equipment. If there are knowledgeable people present, you will find that these people busy next to these equipment are the real top machining talents in their country.

    "Mr. Donald! Here you are! The aircraft parts you designed have been basically processed and can be finally assembled at any time." when Donald entered the workshop, an old man with white hair saw Donald''s arrival and immediately came to him and said to Donald.

    "Hello, Mr. Hessen! Let''s arrange personnel to carry out the final assembly of the aircraft. I have bought all the glass for the aircraft this time and it is now in our warehouse," Donald replied.

    Then Donald and Hessen directed the technicians in the workshop to move all the processed parts to the assembly workshop of the base, and they followed the workers to the general assembly workshop.

    When they walked into the final assembly workshop, what first came into the eyes of Donald and Hessen was the framework of a huge aircraft that did not belong to the era.

    From the frame of the aircraft, the total length of the aircraft is nearly 100 meters, and the wingspan is larger, at least more than 110 meters. At the same time, according to the size and shape of the aircraft.

    The power system or engine used by this aircraft is not a propeller engine, but a jet engine that does not belong to this era. According to the engine pod of this aircraft, this huge aircraft has 16 engines, that is, there are eight engines on the left and right wings.

    "What a perfect machine! Mr. Donald, although he said that the plane was made under our auspices, and we see it every day.

    But every time I see this big guy, I am extremely proud and proud. This is definitely the top war machine of our human civilization. Even the steel giants running across the sea can''t be compared with the people in front of me.

    Mr. Donald, you can design and manufacture such a plane. You are definitely one of the greatest scientists of our human civilization in this century, "said Hessen next to Donald.

    You should know that Hessen himself is one of the most famous scientists in the world and has made amazing achievements in many fields, so generally speaking, he will never praise a person like this, but he absolutely admires Donald. After all, he is absolutely worthy of his praise for being able to design such an aircraft.

    After all, the difficulty of designing and manufacturing such an aircraft is beyond the level of the whole era.

    Donald did not speak, but quietly looked at the big guy in front of him. They all said that the plane is the most perfect embodiment of the industrial level of human civilization. Donald absolutely agreed with him.

    Of course, what he recognized was not the toys driven by internal combustion engines and propellers in this era, but large jet aircraft made of various metals and synthetic materials like the plane in front of him.

    In fact, the plane in front of Donald was not designed by himself, but was designed by a professional aircraft design shop in the science and technology mall. Apart from the design of the aircraft, Donald spent 50000 energy coins to get it at the beginning, not to mention that Donald paid a lot of money to make the aircraft.

    Although the aircraft has not been manufactured so far, Donald has spent nearly 100000 energy coins to manufacture the aircraft. Fortunately, the keel, engine and other internal structures and equipment of the aircraft have been manufactured and installed. Now all that is left is the shell, otherwise, Donald was really worried that he didn''t have enough energy coins to complete the manufacture of the aircraft.

    For the next few days, Donald stayed in the assembly workshop every day and assembled the aircraft with technicians.

    However, when his aircraft was about to be assembled, an unexpected news made him very angry, that is, there were spies in his base. You know, all the people in his base were strictly censored. They were allowed to enter only after confirming that their ancestors had no problems for 18 generations, and they were still not allowed to go out after entering, However, even with such a strict selection method, spies still appeared.

    In fact, what he didn''t know was that the spy found by their national military headquarters was the soldier who took a piece of glass from his warehouse. On the way to transfer the glass, he was found, but unfortunately, the glass had been successfully transferred by the spy.

    However, Donald is thankful that although the glass has been moved and disappeared, his base has not been exposed. After all, the spy actually had to do so because his family was threatened by the enemies of their country.

    This incident also made Donald clearly aware of the means of the enemy of their country, and also made him realize that the families of the soldiers in the base must be protected.
