In the luxury sports car, Lu Yisha didn't say anything, and she stared at the engine structure diagram that Zhang Yuan casually drew.

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

He believed that Lu Yisha would accept it. His engine body uses the technology of the Golden Heavenly Realm, but in some key points, he uses advanced technology from the place where the starry sky shines. For the Golden Heavenly Realm, this is a genius-like innovation, which directly opens up a new field.

For an engine manufacturer, this thing has a fatal appeal, and Lu Yisha has no reason to refuse this cooperation.

Five minutes later, Lu Yisha spoke: "Your engine is just a sketch. Although I can see a lot of extremely creative new designs, these new designs have not been tested by practice."

The words were very clear, and Lu Yisha was already very moved, but she wanted Zhang Yuan to take out a finished engine so that she could be convincing enough.

Of course Zhang Yuan could understand, Lu Yisha wanted to invest real money and silver, so of course she didn't dare to take risks easily.

After thinking about it, Zhang Yuan said: "This is the situation. I have conducted small-scale experiments to verify that this new engine is feasible, but it takes a lot of money to build a finished product. You know, I'm relatively tight now."

“If the funds are enough, how long will it take for you to get a finished product?”

"Give me 4 days, I have completed the printing process of each part. In 4 days, you can see a sample of a low-power version." Zhang Yuandao.

Lu Yisha blinked her bright eyes, and her face was a little incredible: "Four days? Low-power version sample? Is it a little faster? And what 3D printer are you using? Don't tell me you are using the most ordinary fusion machine on the market?"

The warship engine has developed to this level today. The technology has undergone countless iterations, and the structure is so complex and sophisticated that it is far beyond ordinary people's imagination. Today, the engines are all modularly designed, divided into 5 large modules, and each large module is divided into dozens of small modules.

Ordinary engine engineers can only be proficient in the design of a small module, and those who are more genius can be proficient in a large module. Even master-level engineers can only have a general grasp of all modules of an engine.

It is simply a fantasy to create an engine for a warship in 4 days and a most basic 3D printer!

Zhang Yuan shrugged: "It's indeed a fusion machine. This kind of printer can be bought for only 600 star coins. Its functions are very complete. I modified it a little, which is enough to complete the creation of an ordinary engine."

Lu Yisha looked at Zhang Yuan with the look of looking at the madman. She really couldn't believe this, but she couldn't easily deny Zhang Yuan. The mechanical skills that this guy had just shown were very profound, and this guy seemed like a madman himself.

If it weren't a lunatic, who would have devoted all his energy and enthusiasm to build a clearly unpractical mecha?

Zhang Yuan faced Lu Yisha's suspicious eyes calmly.

After a long time, Lu Yisha sighed: "I really don't want to believe you, but you have convincing skills. You definitely need funds to build engine samples. I can fund you in this regard. Tell me, how much do you need?"

Zhang Yuan smiled slightly, he had already calculated: "It's about 3,000 star coins."

As soon as he finished speaking, a prompt sounded a sound of his electronic wallet, showing that 3,000 star coins were recorded. Lu Yisha smiled bitterly: "This is my private funding. I don't believe you can create an engine sample in 4 days, but I still have a hint of fantasy. But if you really build it, then our Tiangong Group will definitely acquire your drawings at a high price, which is enough to make you create a real mech."

Zhang Yuan snapped his fingers and said, "Then you can wait for my good news."

As he said that, he opened the car door and walked out. While walking, he thought about how much the performance of this engine sample should be controlled.

"This engine performance should be amazing, but it will not be powerful enough to subvert. In this way, I will naturally gain the reputation of a mechanical genius. Not to mention the money, the reputation will definitely spread throughout the Golden Heaven Realm. At that time, I will create a truly usable mecha, which will not be shocking."

After confirming the performance level of the engine, Zhang Yuan began to simulate specific construction details again. His spirit is extremely powerful and his calculation speed is not much slower than that of a supercomputer. While walking, he thought, and when he returned to the apartment, he had a mature plan in his mind.

At this time, the optical quantum supercomputer he bought also arrived. After he turned on the computer, he placed an order to purchase materials and tools, and did things one by one, in an orderly manner.

On the other side, after Lu Yisha watched Zhang Yuan disappear into the corridor, her eyes returned to the mechanical drawings on the sports car holographic screen. She packed the sketches one by one and sent them to her friend Lily.

She was not worried that Lily had stolen these drawings. The credit system of the Golden Heaven Realm was very perfect. If Lily did this, it would be a self-destruction of her future.

"Lily, I got some new things from Zhang Yuan, please help me see." Lu Yisha also opened up Lily's communication.

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

Lily's voice came to an abrupt end. After a while, she said: "Lu Yisha, this mecha is simply a genius design. According to this idea, it seems that it can build an amazing individual combat machine, but this mecha is too powerful and no one can control it, but we just need to weaken the power a little."

"I know, I know, this mecha drawing is just a fun thing. You just need to play with dessert after meals. What I want you to look at the engine drawing behind. What do you think?"

"Wait, I'll take a look." Lily turned to the engine design drawing. At first she just took a casual look, then she took a second and third eyes, and then a pair of eyes were glued to the drawing.

This time, she took it very seriously.

From time to time, she would perform some verified calculations on the holographic screen beside her. When she saw the subtleties, she couldn't help but issue an exclamation like "Oh~ah~my god".

As she looked at it, the content of the drawing suddenly disappeared. Lily immediately searched the data packet sent by Lu Yisha, but found nothing, and the drawing was only half.

"Damn~ What about the second half? Why is this drawing only half?!" Lily was going crazy. It felt like when she was in love with her ex-boyfriend, the guy always came to an abrupt end when she started to be happy, which made her whole body feel bad.

Lu Yisha was very familiar with Lily, so she naturally knew her depression at the moment. She laughed and said, "Zhang Yuan will give me half of it. Judging from your reaction, this new engine should be available in most cases."

Lily shouted: "More than just available! I tell you, this engine is amazing. If it can be really built, its energy efficiency may exceed 40%!"

"40% that seems really good." Lu Yisha's heart was filled with expectations. She now had the urge to run to Zhang Yuan and watch him create engine samples.

Lily was in a more urgent mood than her: "Wait, you just said that this drawing was given to you by Zhang Yuan? Which Zhang Yuan is this? Don't tell me that Zhang Yuan is very good at playing mecha games?"

"It's that Zhang Yuan." Lu Yisha smiled.

"This guy is actually a mechanical engineer? Oh, that's right. If it weren't for him, others wouldn't have been spared to spend so much energy on designing a mecha. This guy is such a lunatic. He can actually design the mecha to this level. I'll come to Bailu City now, and I want to meet this guy!"

While Lily was talking, Lu Yisha heard a sound of packing up her things during the communication. Obviously, the friend left as soon as he said that he was not ready to waste time at all.

"Hey~ don't worry. This guy just told me shamelessly that he could build an engine sample in four days. Now let's not bother him, just see what he can make in four days."

"Clang! Clang~"

There was a sound of something falling to the ground in the communication, and Lily was obviously surprised: "This guy is really brave enough to say it? Four days? If he could make it out in four years, I would be awesome! Four days? I can't tell the world!"

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

Lily was quiet for a while, then suddenly said, "No, right? You can't hide it from me. You verbally don't believe it, but in fact you still have expectations. My God, Zhang Yuan's trick is quite capable of cheating you, and he can actually cheat you like this. Tell me, he cares about how much money you have asked for?"

Lu Yisha hurriedly denied: "He didn't care about my money."

But just as Lu Yisha knew Lily, Lily knew her best friend very well. When she heard her words, Lily exclaimed: "So, did you really give him money? How much did you give?"

Lu Yisha was half-believing and half-doubted by Lily's words. She found that she was actually a little embarrassed to speak: "33,000 star coins."

"Oh~ You are indeed a wealthy lady, and you can just throw money at people." Lily lamented: "Lu Yisha, I tell you that no one can build an engine alone in 4 days, even a mature engine, let alone a new engine. Zhang Yuan is indeed quite high in the field of machinery, but I dare to guarantee that he is definitely lying to you this time! Look, after four days, he will definitely make excuses and say that he can't make it, and then he will say to give him a few more days, and then he will hint you to give money.Lu Yisha, you have to know that not everyone cares about credit."

"Not it? I don't think he is like this." Lu Yisha felt very worried now.

Lily snorted, "Who have you seen the word "liar" written on your forehead? If you don't believe it, you'll know it after four days."
