In the luxury sports car, Lu Isa didn't speak, her eyes stared at the engine structure diagram drawn by Zhang Yuan casually without blinking.

Zhang Yuan was not in a hurry, and patiently leaned on the well-wrapped seat of the sports car, waiting gracefully.

He was sure that Luisa would accept it, and the main body of his engine used the technology of the Golden Heavens, but in some key places, it used the advanced technology of the Starry Land. For Golden Sky Domain, this is a genius-like innovation, which directly opens up a whole new field

For an engine manufacturer, the thing had a fatal appeal, and Roisa had no reason to turn down the partnership.

After five minutes, Ruisa spoke: "Your engine is just a sketch, and although I can see a lot of extremely creative new designs, these new designs have not stood the test of practice......"

The words are very clear, Lu Yisha is already very moved, but she wants Zhang Yuan to come up with a finished engine, so that it is convincing enough.

Of course, Zhang Yuan can understand that Lu Yisha wants real money to invest in it, and of course she doesn't dare to take risks easily.

After thinking about it, Zhang Yuan said: "The situation is like this, I have already done small-scale tests to verify the feasibility of this new engine, but it takes a lot of money to build a finished product. You know, I'm pretty tight on money right now. ”

"If you have enough money, how long will it take you to get a finished machine?"

"Give me 4 days, I've got a finished print for each part. After 4 days, you will be able to see a low-power version of the sample. Zhang Yuandao.

Lu Yisha blinked her crystal eyes, and there was some incredulity on her face: "Four days? Low-power version of the sample? Isn't it a little faster, and what kind of 3D printer are you using? Don't tell me you're using the most common melter on the market? ”

The warship engine has developed to this extent, and the technology has gone through countless iterations, and the structure is far more complex and sophisticated than ordinary people can imagine. Today, the engine is fully modular, divided into five large modules, each of which is divided into dozens of smaller modules.

The average engine engineer can only be proficient in the design of a small module, and the genius can be proficient in a large module, while even a master engineer can only have a general grasp of all the modules of an engine.

It took 4 days for a single person to build an engine for a battleship with a basic 3D printer, which is simply a fantasy!

Zhang Yuan shrugged his shoulders: "It is indeed a light melting machine, this kind of printer can be bought for only 600 star coins, the functions are very perfect, I modified it slightly, it is enough to complete the construction of an ordinary engine." ”

Lu Yisha looked at Zhang Yuan with the eyes of a madman, she really couldn't believe this kind of thing, but she couldn't easily deny Zhang Yuan, this guy had just shown very deep mechanical skills, and this guy himself seemed to be a madman.

If you weren't a madman, who would put all your energy and passion into building a mecha that was obviously not practical?

Zhang Yuan calmly faced Lu Yisha's skeptical eyes.

After a long time, Lu Yisha sighed: "I really don't want to believe you, but you have convincing skills." You're definitely going to need money to build engine samples, and I can fund you in that, like, how much do you need? ”

Zhang Yuan smiled slightly, he had already calculated it: "About 3,000 star coins." ”

As soon as he finished speaking, a prompt sounded in his e-wallet, showing that 3,000 Star Coins had been credited to his account, and Lu Yisha smiled bitterly: "This is my private funding, I don't believe you can build a prototype of an engine in 4 days, but I still have a trace of fantasy." But if you really build it, then our Tiangong Group will definitely buy you this set of drawings at a high price, which is enough for you to build a real mecha. ”

Zhang Yuan snapped his fingers: "Then you just wait for my good news." ”

With that, he pulled the car door open and walked out, thinking about how well he should control the performance of this engine sample.

"This engine should be impressive, but not so powerful as to be subversive, so naturally I'll gain a reputation as a mechanical genius, money aside, fame will definitely spread all over the Golden Realm. When the time comes, I will build a truly usable mecha that will not be shocking to the world. ”

After determining the performance level of the engine, Zhang Yuan began to simulate the specific construction details, his spirit was incomparable, the calculation speed was not much slower than that of a supercomputer, and he thought about it while walking, and when he returned to the apartment, he already had a mature plan in mind.

At this time, the optical quantum supercomputer he purchased also arrived, and after he turned on the computer, he placed an order to buy materials and tools, and things were done one by one in an orderly manner.

On the other side, after seeing Zhang Yuan disappear into the corridor, Lu Yisha's eyes returned to the mechanical drawings on the holographic screen of the sports car, which she packed up and sent to her friend Lily.

She wasn't worried about Lily stealing these blueprints, Golden Skyland's credit system was very perfect, and if Lily did that, it would be self-destructive.

"Lily, I got some new things from Zhang Yuan, you can help me take a look." Luisa also opens up Lily's communication.

Lily's complaint came from the communication: "Miss, you are treating me as a free laborer...... Hey? ”

Lily's voice stopped abruptly, and it was a long moment before she said, "Ruisa, this mech is a genius design." According to this line of thinking, it seems that we can build an amazing individual combat machine, but this mech is too powerful for anyone to control, but we just need to weaken the power a little bit......"

"I know, I know, this mecha blueprint is just a thing to play with, you can just think about it as a dessert after dinner. What I want you to see is the engine drawing in the back, what do you think? ”

"Wait, I'll see." Lily flipped to the engine blueprint, and at first she just glanced at it casually, then she looked at it a second, then a third, and then a pair of eyes were glued to the drawings.

This time, she looked at it very seriously.

Every now and then, she would do some verification calculations on the holographic screen next to her, and when she saw the subtleties, she couldn't help but let out interjections like 'oh~ah~oh my god'.

Just looking at it, the contents of the drawing were suddenly gone, and Lily immediately went to rummage through the data package sent by Luisa, but found nothing, and the drawing was only half cut.

"Hell ~ what about the second half? How come this drawing is only half there?! "Lily was going crazy, it felt like when she was in love with her ex-boyfriend, and that guy always stopped abruptly when she started to have fun, and it made her feel bad.

Lu Yisha was very familiar with Lily's temper, so she naturally knew her depression at the moment, and she grinned: "Zhang Yuan will give me half." Depending on your reaction, there is a good chance that this new engine should be usable. ”

Lily shouted, "It's not just usable! I'll tell you, this engine is amazing, and if it could be built, it could be more than 40% energy efficient! ”

"40%...... That seems really good. Lu Yisha's heart was suddenly full of anticipation, and she now had the urge to run to Zhang Yuan's side and watch him build engine samples.

Lily was even more anxious than her: "Wait, you just said that this drawing was given to you by Zhang Yuan?" Which Zhang Yuan is this? Don't you tell me it's Zhang Yuan, who is very good at playing mecha games? ”

"It's that Zhang Yuan." Ruisha laughed.

"This guy is still a mechanical engineer? Oh, yes, if it weren't for him, no one else would have bothered to spend so much energy designing a mech. This guy is really crazy enough to design a mecha to this extent...... No, I'm coming to White Deer City now, I want to meet this guy! ”

As Lily spoke, Louisa heard the sound of packing up her things in the communication, and it was clear that the friend was not prepared to delay at all.

"Hey~ Don't worry. This guy just told me that he could build an engine prototype in four days. Now let's not bother him, just see what he can do in four days. ”

"Bang dang! Dang Chang~"

There was a sound of something falling on the ground in the communication, and Lily was obviously surprised: "How dare this guy say it?" Four days? If he can figure it out in four years, I'll be great! Four days? I don't know how thick the sky is! ”

Lu Yisha smiled dryly, "I don't believe it either, but it's only four days anyway, isn't it?" ”

Lily was silent for a while, and then suddenly said, "No, no, you can't hide it from me, you don't believe it verbally, but you actually have expectations." My God, this Zhang Yuan's fooling ability is not small, and he can deceive you like this. Say, how much money does he care you for? ”

Lu Yisha hurriedly denied: "He didn't care about me asking for money." ”

But just as Lu Isa knew Lily, Lily also knew her best friend very well, and as soon as she heard her words, Lily exclaimed, "So, did you really give him money?" How much was given? ”

Luisa was skeptical of what Lily said, and she realized that she was a little ashamed to speak: "3.......3000 Star Coins." ”

"Oh~ You are really a wealthy lady, and you will take money and smash people casually." Lily lamented, "Roisa, let me tell you, no one can build an engine in four days alone, not even a technically mature one, let alone a new one. This Zhang Yuan's level in the mechanical field is indeed quite high, but I dare to pack a ticket, he is definitely lying to you this time! You see, after four days, he's going to make excuses that he can't do it, and then he's going to give him a few more days, and then he's going to go on to suggest that you're going to give money. You know, Roisa, not everyone cares about credit. ”

“...... Not really, right? I don't think he's like that. "Ruisa is very empty now.

Lily snorted, "Have you ever seen anyone write the word liar on the door of their head?" If you don't believe it, you won't know in four days. ”

"Then I'll wait 4 days." Ruisha hated herself for being hot-headed, and if she had been deceived, she would have died of laughter.
