"Zhang Yuan, what's the use of this?"

Emily sat next to Zhang Yuan's small workbench and asked, pointing at a strange-looking part.

This part is carefully placed on a magnetic levitation base. It is roughly spherical in shape and is only about 1 cm in diameter. There are many complex structures similar to multi-faceted gears on the surface. Each surface on the part is as smooth as a mirror, which makes people feel very precise at a glance.

Zhang Yuan sat behind the workbench and walked around between three 3D printers (two of which were newly purchased), optical quantum intelligent brain, and several assembly machines of different sizes, and was very busy.

Of course, this is just a physical busyness. In terms of thinking, Zhang Yuan is very relaxed. His current workload is completely a pediatrician compared to the rhodium magnetic engine. Zhang Yuan simply regards it as a relaxing moment.

After hearing the sound, he looked back and said, "That? I created it for experiments."

"Experience? This thing looks so beautiful." This part is delicately like a work of art, which makes people love it when they see it. Emily couldn't help but want to reach out and touch it.

"Don't move, there is dust-proof and high pressure field on the surface of the parts, and the arms will hurt... Oh~"

Before Zhang Yuan finished speaking, Emily touched the parts with her fingers, and then she hugged her right arm and looked at Zhang Yuan with tears in her eyes: "The arm is numb, what should I do?"

"It's okay to rest for half an hour. Don't touch the parts on this workbench in the future." Zhang Yuan warned. Seeing that Emily was still tearful and a printer was empty, he casually printed a model of the most advanced and handsome eagle warship in the golden heavenly realm and handed it over, which was considered comfort.

The warship was also very delicate, and it looked like it was real. Emily burst into tears and laughed. She no longer bothered Zhang Yuan, and just watched Zhang Yuan busy around.

When he was free, Zhang Yuan turned his head and looked at the hall. Seeing that Fang Ming and others were not there, he said, "Why are you the only one? What about the three of them?"

"We just had a bet with the Flame Team, and we won again. This time we won a full 700 star coins, so the three of them went out to be casual." Emily tossed and turned around and played with the battleship model.

Win again? This matter was not beyond Zhang Yuan's expectations. After he purchased two printers again, the printing speed was greatly accelerated. Currently, there are 3 virtual cockpits in the team, and the team's combat effectiveness has been improved by several levels. It is not surprising to win, but the news is lost.

However, Fang Ming and others are indeed talented, otherwise it would be impossible for them to adapt to driving in the virtual cabin in a short period of time.

"Why didn't you go?" Zhang Yuan asked, taking out a freshly baked engine part from the 3D printer.

When he got the part, he felt that there were some flaws in this part, which was a little different from the parts parameters he needed. If he forced the part to use, the engine assembled finally could also operate, which was the efficiency would be reduced by a few percent, but there was no need to rebuild it. Zhang Yuan carefully touched the surface of the part, then picked up the small high-hardness file on the side, rubbed it gently on the defect, and then touched it carefully, and the defects had disappeared and the parts were perfect.

When Emily saw this scene, her eyes widened again. Such precise parts were actually made of files. Can this still be used? But she didn't know what Zhang Yuan wanted to do, so she could only keep this matter in her heart.

"This virtual cabin is good, but it consumes too much energy to use. I am so tired now that I want to take a good rest. I don't have the energy to play crazy with them."

Zhang Yuan nodded: "The virtual cabin requires physical fitness. You must exercise well and improve your physical strength so that you can enjoy the pleasure of virtual driving."

"I found out too." Emily touched her arm. Because of operating the virtual cabin, her muscles were sore and her exercise intensity was too high.

At this time, Zhang Yuan completed the construction of the last engine part. He turned off the printer, walked to the assembly machine beside him, and began to assemble the engine samples.

He made the assembly machine in this small workspace with a printer himself. The one he is using now is very simple in appearance, with a length and width of about 30 cm. It looks like an iron rack built casually, but it is very useful.

Zhang Yuan put all the hundreds of engine modules that had been assembled before in place, and then put these small modules together like building blocks.

He assembled very quickly. Emily beside him saw Zhang Yuan's hand so fast that it almost appeared afterimage. A crisp sound of "ding ding ding" came from his ears. In just 10 minutes, a small iron lump appeared in front of Zhang Yuan.

The length, width and height of this thing are not more than 10 cm, and can be picked up with one hand. Its lines are very smooth, the surface is silver, and there are a lot of precise and mysterious golden patterns on it, full of indescribable sense of futuristic science fiction.

"Is this?" Emily asked curiously.

"A power engine is similar to the engine used in a hover car. Of course, this is just a sample, and the power output is not high." Zhang Yuan smiled. What he said was not wrong. In the Golden Heaven Realm, the engines of the hover car and the warship are universal, but there is a gap in the engine power.

Emily didn't understand the difference, but she still felt that Zhang Yuan was very powerful. While countless peers were still fighting in the game, he was able to build a hover car engine, which is really admirable.

Just when the little girl felt that Zhang Yuan was very good, Zhang Yuan called Lu Yisha's message: "Hey, are you free now?"

Lu Yisha's voice immediately rang out: "Of course I have time, tell me, what's the matter?"

Zhang Yuan was stunned: "Miss Lu Yisha, you are so noble that you have forgotten so much. Four days ago, didn't you ask me to create an engine sample? I'm done now."

As soon as he finished speaking, he heard a 'clang' sound coming from the communication, as if something had fallen to the ground. The sound seemed to be a water cup, and then a violent cough. After a while, Lu Yisha's voice sounded in the communication: "You mean, you really built the engine? Don't lie, it's not good for you."

As soon as Lu Yisha finished speaking, another female voice sounded in the communication. Compared with Lu Yisha's soft voice, the voice seemed crisp and lively: "Your name is Zhang Yuan, right? Haven't you built a good engine? You are waiting at home now, and we'll come here to inspect the goods now."

"no problem."

Zhang Yuan knew that what he did was a bit shocking. This was the huge gap between the strong man in the starry sky and ordinary people. In fact, if you use magical terms, Zhang Yuan is almost a demigod-like character now.

On the other side of the communication, Lily stood beside Lu Yisha and groaned: "Building a new engine in 4 days is really a fool. Even if he has eight hands, it's useless. Lu Yisha, wait and see how I expose him."

Lu Yisha was a little hesitant: "Can he build it before? No matter what, as long as this engine is really useful."

Lily shook her head confidently: "It can't be that he made it before! I've checked the origin of this guy. He's just a scholar. I've also checked his recent purchase of items. He didn't have the equipment to build the engine before. So, the engine he took out this time must have a big problem."

Lu Yisha stopped talking. Her best friend was a super academic master at school back then. Since she said so, she had to choose to believe it.

The two left their residence, and the driver was in a luxurious sports car and rushed to the downstairs of Tianxin's apartment where Zhang Yuan lived.

Lu Yisha opened the car door and got out of the car first.

As soon as she got off the car, she was stunned for a moment. Seeing her like this, Lily asked strangely: "What's going on... Hey, Zhang Yuan, you are already waiting for us... This one by you... Huh?"

Lily's eyes suddenly settled on the small silver metal block next to Zhang Yuan. The intuition of an engine designer told her that this was an engine, and a new engine that the golden heavenly world had never been before.

Her confidence just now was shaken and she couldn't help but mutter: "Is this true?"

Zhang Yuan also saw the two of them. In his eyes, Lu Yisha was a standard white, rich and beautiful woman, with grace and nobleness. Beside her was a tomboy-like girl. This girl was about the same age as Lu Yisha, with short hair, delicate facial features, and wearing vests and trousers, looking very neat.

He reached out and picked up the engine beside him and walked towards the luxury sports car: "I have built the engine, but I don't have the test conditions here. Lu Yisha, your company should have a special engine test venue, right?"

Lu Yisha's eyes kept staring at the light silver metal block that was casually held by Zhang Yuan in her hand. After looking at it for half a minute, she found that with her professionalism, she could no longer judge the authenticity of this engine.

Lily walked up and looked at the engine Zhang Yuan was holding. She looked at it for a long time before she said, "Okay, the appearance is very exquisite, it's very rare. Zhang Yuan, tell me about its power parameters?"

"Of course." Zhang Yuan brought this 'iron lump' into the sports car. After the three of them sat firmly, he quickly wrote down the engine's parameters on the holographic screen of the main control brain: "This engine is just a small sample. The power output limit I designed is about 1028 horsepower, and the power output method is space force field. If it is powered by a standard small titanium crystal battery, it can run in the extreme state for about 5232 hours, and the energy conversion efficiency is about 47%..."

"This is impossible!"

Lu Yisha and Lily shouted at the same time.

Lu Yisha frowned and said, "As such a small thing, the output power can reach 1028 horsepower. Isn't it too high?"

The Phantom Engine produced by her family is more than 4 meters long and more than 2 meters high, and the maximum output is less than 20,000 yuan, but its size is more than thousands of times that of the small thing Zhang Yuan took out.

Lily also sneered: "I won't talk about the engine volume for now. It's not impossible to make this thing more refined, and it's not impossible to reduce the volume. But the energy efficiency of the highest space force field engine is only about 39%. The latest and highest-end Phantom Engine in Luyisha's family is at this level. You will increase it by 8% at once, which is too exaggerated!"

Zhang Yuan threw away the little engine in his hand and smiled and said, "What's the point of refuting me now? The engine is there, just take it back and test it," he said.

Lu Yisha immediately started the sports car, and the engine roared with a 'woo~'. The sports car rushed into the fast lane a thousand meters high like a swift cheetah, and rushed towards the engine factory of her family.

She now believes that what Zhang Yuan said is true. When things have reached this point, it makes no sense for him to lie to others anymore.

Lily, who was standing by, had no voice. What happened today exceeded the cognitive limit she had established in the past. What she had in the past seemed to be no longer used as a criterion for judgment.

The sports car was running lightning all the way. About half an hour later, the three of them arrived at a professional engine laboratory in the west of Bailu City. Zhang Yuan then took out the engine and walked towards the laboratory.

Lily glanced at the corner of her eyes and twitched: "Your engine looks very precise, you just hold it like this, aren't you afraid of something wrong?"

Zhang Yuan smiled and said, "It's probably going to be a problem if someone else holds it, but I'm fine. Even if it's really broken, I can repair it."

"Show up!" Lily stopped talking.

On the other hand, Lu Yisha had quickly arranged the test program. The tester in the laboratory came over and connected Zhang Yuan's engine with a strange look on his face, and began to test the engine performance.

Lu Yisha was eager to find out the result, so she was waiting outside the laboratory, with Lily and Zhang Yuan accompanying her.

Time passed by minute by minute. About 2 hours later, a gray-haired old man ran out of the laboratory. As soon as he came out, he looked at Lu Yisha: "Miss, where did your engine come from?"

Lu Yisha was full of expectations: "Brother Zhang, how is the situation?"

The old man who was called Zhang Bo also had a strong shock in his eyes: "This is a perfect space force field engine, with an energy conversion efficiency of up to 47.3%, and his power output is very stable. After it is stable at the limit, the engine surface temperature has always been at a low temperature of 321 degrees. When it is running, the noise is always below 10 decibels. What's more rare is that its size is so small... My God, this is a miracle, it is like a magical artifact created by a god!"

"Gudong~" A voice came from beside her. It was Lily. She staggered and hit the chair on the side. This matter completely surpassed her perception. How could a person build such an excellent engine in four days? Is this guy still a human?

But Lu Yisha was ecstatic. She was first of all, a businessman and would not worry about how Zhang Yuan built the engine. She only knew now that the new technology contained in this engine could increase the competitiveness of the group to a point beyond the reach of others!
