Lingmei was still crying, and the quantity and quality of her tears were obviously disproportionate to the size of her body. Xu Zheng saw her sprinkling water like a waterfall, mourning her flying machine at all cost.

Old, middle, and young, all three men looked at her with a headache, and had no experience in dealing with women who cried endlessly. Mark's attention was all attracted by Lingmei's large number of tears, and he stretched out his head curiously to look at her, estimating in his heart how many tears she could shed.

In the end, the three men and one magic envoy all looked down on her, Lingmeimei was addicted to crying, and after half an hour, she didn't let go of the sunny sun.

Xu Zheng couldn't stand it at all, and said irritably: "Isn't it just a broken plane, Mark, bring it to me and take a look." ”

Ao Sen looked at Xu Zheng and said, "Son, don't mess around if you don't understand." If you make it worse, this little girl can drown you with tears!"

Xu Zheng rolled his eyes, it was just a broken plane, and it was so backward. When he didn't have a man-machine merger, the hand-made one-man flying machine was a hundred times stronger than this, and of all the works in the elite school, he was the only one who dared to install the plasma thruster on the one-man flying machine. What the hell is this?

At that moment, I walked to the side of the aircraft, observed it, opened the power room in the middle of the fuselage, and looked inside.

Lingmeimei screamed: "Don't touch it!" After crying for half a day, she also felt that these humans were indeed quite friendly, the white-haired old man was the most kind and could only laugh at Mimi, the middle-aged man had a scary beard, but there was no threat, not to mention the teenager's, eh...... It's quite flattering. As for the weird puppet, it just looked a little scary, but it was actually very kind, and the fear was gone, and it dared to shout at the three male humans.

Xu Zheng ignored her and took a look. He said with a look of embarrassment: "It's still a steam engine?! You can fly with this engine, cow!" reached in and pulled a few times. With an incredulous face, he said: "Three-pronged retrograde linkage transmission...... Damn, it's backward enough. The shaft sleeve universal coupling is quite passable. Using ceramics as wear-resistant parts is so-so. Wooden pistons ...... my mother."

Ling Meimei was very dissatisfied and said: "It's pine ironwood! It expands when heated, and it has good heat resistance." It's not easy to corrode, it's stretchable, it's very sealed! It's my first achievement! No one else in the clan knows this technology!"

"Stupid!" Xu Zheng said: "If I change it, I will use 90 percent dense silver plus 3 percent Ye's steel, and then mix 4 percent ferroplasma, and finally add 3 percent chromium Belle particles to melt together to make a piston matrix." After the piston is made, it is slotted on it, and it looks like three to four passes. If you embed this kind of pine ironwood you mentioned, it will be much stronger than yours. With your current technology, this can be done easily. ”

Ling Meimei thought as she listened. At first, he was still flattening, not believing that a human was qualified to criticize the design of the gnome. The more I listened, the more frightened I became, and carefully filtered Xu Zheng's design in my heart. It's unspeakably clever. The complex forging process makes such a piston far exceed the performance of pine ironwood, and the sealing ring of pinewood makes up for its shortcomings. What's even smarter is that once wear occurs, the sealing ring can be replaced, and there is no need to manufacture a monolithic piston at a high cost. This solves the problem of piston breakage, which has not been solved. The high cost, time-consuming and labor-intensive production of Pinus tabuliformis ironwood has solved the problem of slow production and shortage of materials.

Ling Meimei raised her head and looked at Xu Zheng in shock: "Do you really understand?!I've never heard of humans and technicians!And that kind of hybrid forging technology is more sophisticated than that of dwarves, how do you know?"

Abel and Orson also looked at Xu Zheng with shocked expressions. Orson asked, "Son, what do you know?" and where did you learn it?"

Xu Zheng smiled wickedly and said, "Secret!"

"You!" Orson said angrily, "I'm your father, there's no secret to speak of!"

"Really?" Xu Zheng squinted at him and said, "One day when you are in a good mood and tell me about your mother, I will tell you this." Don't be stupid, you didn't say a word about your mother last night. I don't know what her name is, what she looks like, or who she is, so don't think you can get by. ”

Ao Sen was stunned, and said with a dark face: "I knew that I was a little lazy when I made you, and what did I do to make my brain so smart......"

When you are made...... Xu Zheng suddenly wanted to hit someone again! And this guy was obviously changing the topic again, avoiding answering.

Yes, everyone has secrets, and if you don't tell it, I don't want to say it.

The two fathers and sons tacitly retreated and were silent. Ao Sen was distracted, and Xu Zheng continued to study Lingmei's plane.

Ling Meimei blinked her ridiculously big eyes, and her fan-like eyelashes made Xu Zheng dizzy for a while, looked at Xu Zheng pitifully, and said, "That...... Uh, humans. ”

"Xu Zheng. My name is Xu Zheng. ”

"Nonsense, your name is Orson Travis Jr. ”

"Shut up!"

Ling Meimei looked at this and then at that, and obviously felt that the black-haired and black-eyed one was much stronger, so she directly skipped Ao Sen and asked Xu Zheng tentatively: "Can you see where the fault is?"

Seeing Xu Zheng's eyes move back all the way, and finally fell on the throttle valve that controlled the steam, Ling Meimei was completely convinced. In other words, it was impossible for her to find this position so quickly, she was more familiar with her own aircraft, and this part often had problems, so she could definitely be here.

Now the question is very straightforward: "I think it's here, too." This throttle valve is a frequent part of the operation, so it often has problems. Can it be fixed?"

Xu Zheng pondered for a while and said, "It's not a big problem. I can make a metal one to replace. The problem is that due to the frequent movement of this part, if you design like this, there will be such a problem, and there will be such a problem. ”

"Why?"

"You're controlled by a steel cable structure, right?"

Ling Meimei nodded: "The steel cable is easy to bend and turn, and it is easy to lay the path." If you add pulleys, it will save effort. ”

Xu Zheng shook his head: "But the steel cable has too many shortcomings, one is the ductility of the metal, which makes it lag behind, and the manipulation must have an advance amount, which is not easy to control." The second is that the performance of the two states of the steel cable is very different, and you are a hot engine, which is hot when running, and it cools down sharply when it is high altitude, and it changes sharply between a cold and a hot, and it is most prone to failure. Let's get a throttle spool and replace it first, so that you can drive it back first. When you go back, I suggest you remove the steel cables and use a rigid hand-pushed structure instead, so that the position of the engine does not change, and the side bulkheads are equipped with control handles. Anyway, you're so small, and the extra space is negligible. ”

A bunch of terms are beautiful and beautiful, what temperature difference, heat engine, engine, side cabin, clouds, clouds. But this did not affect Comrade Ling Meimei's eyes towards Xu Zheng to become more and more enthusiastic, and finally sublimated into fanatical worship.

This is determined by the eccentric aesthetics of the dwarf, looking at a person, it doesn't matter if he is beautiful or ugly, there is no requirement for height or shortness, it is meaningless to be of my race, the key is whether you have excellent skills, and someone like Xu Zheng who can make Lingmei stunned at once, looking at the entire Aris continent, is still the first one so far.

Therefore, in a moment, Ling Meimei's admiration for Xu Zheng is like the water of the Tuotuodar River, continuous and surging. What the little girl wants to do most now is to immediately conjure up a pile of parchment scrolls, write down every word Xu Zheng said, and then make a family scripture and recite it every day.

"You're amazing!" Lingmeimei looked at Xu Zheng feverishly, and her big eyes that blinked too often made Xu Zheng dizzy.

"Genius! Genius! What a genius! You are even more powerful than the clan's clan-level technicians! I must go back to the clan and report to the elders that the human race has produced a genius technician! Oh! I must write your name on the plane! Quick, quick! Please tell me, what else needs to be improved on my plane? Next month is the first clan exhibition of the year, and I will use it to compete in the competition, and when the time comes, I will scare the eyes of all the elders! Hmph, they still say that I am not qualified to take the senior technician exam. The villain jumped wildly on the ground and rubbed his hands, full of confidence and high morale, it seems that with the help of Xu Zheng, a Terran technician who came out halfway, her work has been able to win the first place, and the position of senior technician is also in her hands.

"Oh, tell me, what else does my baby need to change?" Ling Meimei had gone crazy, and that battle made Xu Zheng think that she would probably kneel down and kiss her toes next moment......

As for the changes, there are too many landlords to change. This broken plane is even more broken than the aircraft of World War I, such as the multi-wing structure, the structure is cumbersome, and the control is clumsy; the engine is still a steam piston linkage transmission, and the heat energy is converted into kinetic energy, and the reciprocating motion is converted into rotational motion, which has almost lost energy in the middle. There are also a series of problems such as climb force and steering. In Xu Zheng's eyes, this plane was almost like a patient who needed surgery all over his body, and for a while he felt like a cow gnawing on a pumpkin, and he couldn't find a place to start.

Seeing Xu Zheng's hesitation, the dwarf's desire to learn in his nature burned Lingmei's heart as uncomfortable as a cat scratching. Thinking that the human race does not like communication technology like dwarfs, and everyone makes selfless contributions to their research for everyone to learn, but like the traditional style of human beings, it needs to be exchanged for equal value, so he immediately said eagerly: "Please tell me." What do you want to exchange? If I have it, I'll trade it for your technology! Just don't refuse me. For a dwarf, missing out on something that can be learned is worse than killing him. Is it okay to have gold coins? Dad has some, I'll bring them all, you can see what kind of technology you can exchange. Gnomes also have a lot of good skills, so maybe you like it. To change or not to change?"

"That's not what I meant...... Uh?" Xu Zheng was suddenly overjoyed, he really had nowhere to find his iron shoes, and it took no effort to get them! All the problems were solved from Ling Meimei, and he got off to a good start.

"Change!" Xu Zheng said categorically.
