Lin Yuan turned back to Shen Wanqing and said, "I guessed right, they have indeed used this thing in the fire control system. ”

Shen Wanqing asked, "Then why didn't he tell you directly?" ”

Lin Yuan said: "The Puran Company is a British company, and Britain regards Germany as a potential military adversary, and will definitely not let this company talk about such an important technology everywhere. ”

Lin Yuan said, pointed to the booth on the side, and said: "Let's go over there and have a look, Zeiss company, German military optics are all produced here, let's go and have a look, maybe there will be surprises." ”

Xu Jingcheng's mind was still on the gyroscope, and he said to Lin Yuan on the side: "Lin Shuai, I wonder if we can make such a gyroscope?" ”

Lin Yuan smiled and said, "I definitely won't make it, this kind of gyroscope has long been outdated, who will use it!" ”

Xu Jingcheng said in surprise: "What did you say? Outdated? "It turns out that the gyroscope displayed at the booth is the most primitive rotor gyroscope, in Lin Yuan's opinion, the gyroscope is too primitive, since it has been able to manufacture low-power lasers, it is enough to directly apply laser gyroscopes on future warships.

Lin Yuan didn't say anything to Xu Jingcheng, and Shen Wanqing walked directly to the booth of Zeiss Company, Lin Yuan once bought optical glass from Zeiss factory with the opportunity of Zhang Jian to open a yarn factory, but with the development of Northeast China, now Lin Yuan can also produce high-quality optical glass.

On the stage, the staff of Zeiss Company was displaying several cameras, and many people in Lin Yuan's delegation had never seen cameras, so they all looked around the staff, and at this time, Lin Yuan found that there was a cabinet-like thing behind the booth, but it was covered with a thick layer of cloth.

Lin Yuan looked at Shen Wanqing, only to see that she was looking at the person above to demonstrate the camera with relish, Lin Yuan pulled her and said with a smile: "Your camera is more than a hundred years ahead of theirs, what is there to see about their things?" ”

Shen Wanqing smiled: "What is there to see? Of course, it's looking for a sense of superiority! ”

Lin Yuan smiled, and pointed to the cabinet covered with a thick tarpaulin with his hand, and said to Shen Wanqing: "I saw that thing covered with a thick cloth, according to the convention of military expositions, things that are covered by other things are really good things." ”

Shen Wanqing said: "This is strange, isn't it an exhibition?" Wouldn't it be nice not to bring them if you don't want others to see them? If you have brought it, why cover it? ”

Lin Yuan said: "Those good things are for some special people to see, if you don't show us this thing is very valuable, our warship design needs to be guided by the enemy's technical situation, so that it can be targeted, now we will find a way to figure out what is under the tarpaulin." ”

Shen Wanqing raised her head, glanced at the cabinet, and found that there was only one guard, so she smiled and said: "This is simple, it is an introductory course for our agents, I want to find a way to attract the attention of that guard, you go over and lift that tarpaulin." ”

Lin Yuan nodded, Shen Wanqing suddenly laughed evilly, and Lin Yuan asked curiously, "Why are you laughing at it?" ”

Shen Wanqing said while laughing: "You are the leader of the mission, the biggest official, but you do such a sneaky thing, if someone finds out, your people will be lost!" ”

Lin Yuan nodded with a smile and said, "That's right, but I won't be caught." ”

Shen Wanqing walked over to the staff member with a smile, pretending to be pitiful and asking him something, Lin Yuan secretly walked to the edge of the tarpaulin, lifted a small crack in the tarpaulin, and before he could see what was inside, he only heard a hearty laugh from behind: "Mr. Lin Yuan's curiosity is really strong!" ”

Lin Yuan couldn't help but be taken aback when he heard this voice, it turned out that the person who spoke was the German Emperor Wilhelm II, Lin Yuan thought: "This time it's good, it's a shame!" ”

Lin Yuan turned around and saw Wilhelm II standing behind him with a few retinues, and Lin Yuan thought to himself: "I have to quickly think of a way to cover up this matter." ”

Unexpectedly, Wilhelm II didn't care about Lin Yuan secretly lifting the tarpaulin, but smiled at the staff: "Hurry up and open the covered cloth, so that Mr. Lin Yuan can see what is going on, they don't have such a thing in China!" ”

The staff member was so fascinated by Shen Wanqing's beauty plan that he came over when he heard Wilhelm II's words, lifted the cloth, and saw a large telescope-like thing exposed.

Wilhelm II saw that the Chinese were curiously gathered around, and his heart was proud, so he asked Lin Yuan: "Do you know what this thing is?" ”

Lin Yuan looked at the optical lens outside and thought, "This must be something like a telescope, maybe it's a rangefinder." Lin Yuan was thinking about it, and suddenly a detail on the lens came into his eyes: the lens was glowing with a dark blue color, Lin Yuan knew that this must be a total reflective film, and pasting this film can make the imaging clearer, Lin Yuan thought to himself: "It seems that the Germans' skills have made a lot of progress." ”

Lin Yuan saw Wilhelm II's inquiring eyes at this time, so he shook his head lightly and said, "I'm really sorry, I haven't seen this thing." ”

Wilhelm II said: "In that case, please go up and experience it." Lin Yuan was about to thank him, but he saw Wilhelm II turn his head, look at Shen Wanqing, and say, "Lady first, why don't you invite this beautiful young lady to experience it first." ”

This sentence made the diplomat behind Wilhelm II fiercely embarrassed, Lin Yuan didn't care, nodded at Shen Wanqing, Shen Wanqing walked behind the instrument, operated it for a while under the guidance of the staff, and then walked down, Lin Yuan thought to himself: "It seems that today's expo is still very interesting, but the place is too big, it is better to let this German emperor come to me as a tour guide!" ”

When Lin Yuan thought of this, he said to Wilhelm II: "Let that beautiful girl tell me what she has done, and I will know what this is." ”

Wilhelm II was suddenly interested, and then Shen Wanqing rubbed her eyes and walked up to Lin Yuan and said, "This thing is so tiring to use. ”

Lin Yuan said, "Tell me what you've done." ”

Shen Wanqing said: "He just asked me to look at something in the distance." Pointing to the beautiful Berlin Royal Museum shining in the sun, he said: "He asked me to operate a cursor-like thing, and let me overlap the cursor with the flagpole in front of the Royal Museum, and when I felt the coincidence, I could see how far away it was from the museum on the scale on the side." ”

After hearing this, Lin Yuan smiled faintly at Wilhelm II and said: "I know the way, this is a stereo rangefinder, the human eye can sense the distance of objects in space, this is called the binocular vision effect, this instrument is to use this effect to complete the distance of the target object." ”

This kind of advanced rangefinder was just equipped by the German Navy, Wilhelm II didn't expect Lin Yuan to know him, and suddenly his face was full of surprise, Lin Yuan thought: "I'll stimulate you again." So Lin Yuan smiled and said, "But I've never seen such a big one." ”
