"Zhang Yuan, what is this for?"

Emily asked, sitting on the small workbench next to Zhang Yuan, pointing to a strange-looking part.

This part is carefully placed on a magnetic levitation base, the shape is roughly spherical, the diameter is only about 1 centimeter, the surface has many complex structures similar to multi-faceted gears, and each side of the part is smooth as a mirror, which makes people feel very precise at a glance.

Zhang Yuan sat behind the workbench, walking between three 3D printers (two of which were newly bought), optical quantum brains, and several assembly machines of different sizes, and was very busy.

Of course, this is just a physical busyness, but in terms of thinking, Zhang Yuan is very relaxed, his current workload is completely pediatric compared to the rhodium magnetic engine, Zhang Yuan is purely a moment of relaxation.

When he heard the voice, he glanced back and said, "That's it?" I built it for experimentation. ”

"Experiments? This thing looks so beautiful. The part is so delicate that it makes people love it, and Emily can't help but reach out and touch it.

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

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

"It's okay to rest for half an hour, and don't touch the parts on this workbench in the future." Zhang Yuan admonished, seeing that Emily was still teary-eyed, and just as a printer was empty, he casually printed a model of the most advanced and handsome Eagle Falcon battleship in the Golden Sky and handed it over, which was considered a comfort.

The battleship is also very delicate, looking at it as if it is real, Emily burst into tears and laughed, she no longer bothered Zhang Yuan, and quietly watched Zhang Yuan busy on the side.

When he was free, Zhang Yuan turned his head to look at the hall, and saw that Fang Ming and the others were not there, so he said, "Why are you alone?" What about the three of them? ”

"We just gambled with the Flame Clan, and we won again, this time we won a full 700 Star Coins, and the three of them went out in style." Emily tossed and turned around with the model of the battleship.

Won again? This was not much surprising to Zhang Yuan, after he repurchased 2 printers, the printing speed was greatly accelerated, and there are currently 3 virtual cockpits in the team, and the combat effectiveness of the team has increased by several levels, it is not strange to win, and it is news to lose.

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

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

When the parts arrived, he felt that the parts had some flaws, and the parameters of the parts he needed were a little worse, and if the parts were forcibly used, the final assembled engine could also run, but the efficiency would be reduced by a few tenths of a percent, but there was no need to rebuild. Zhang Yuan carefully touched the surface of the part, then picked up the high-hardness file on the side, rubbed it lightly on the flaw, and then touched it carefully, the flaw had disappeared, and the part was perfect.

Emily saw this scene, and her eyes widened again, such a precise part, even with a file, can this still be used? However, she didn't know what Zhang Yuan wanted to do, so she could only hold it in her heart.

"This virtual cabin is good, but it's too physically exhausting to use, I'm so tired and panicked now, I just want to take a good rest, how can I have the energy to play crazy with them."

Zhang Yuan nodded: "The virtual cabin requires physical fitness, you have to 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 the operation of the virtual cabin, her muscles were sore and sore, and the intensity of the exercise was too high.

At this time, Zhang Yuan finished building the last engine part, he turned off the printer, walked to the assembly machine on the side, and began to assemble the engine sample.

The assembly machine in this small workspace is made by himself with a printer, and the one he uses now is very simple, only about 30 centimeters long and wide, and it looks like an iron frame built casually, but it is very easy to use.

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

The speed of his assembly was very fast, and Emily on the side saw that Zhang Yuan's hand was so fast that there was almost an afterimage, and there was a crisp sound of 'ding ding ding' in his ears at the same time, and in just 10 minutes before and after, a small iron bump appeared in front of Zhang Yuan.

The length, width and height of this thing are no more than 10 centimeters, you can pick it up with one hand, its lines are very smooth, the surface is silver, and there are a lot of intricate and mysterious golden lines on it, full of an indescribable sense of futuristic sci-fi.

"What is this?" Emily asked curiously.

"A power engine is similar to the engine used in a hovercar, of course, this is just a sample, and the power output is not high." Zhang Yuan said with a smile, what he said is not wrong, in the Golden Sky Domain, the engines of the hovering car and the battleship are common, but there is a gap in engine power.

Emily doesn't understand the difference, but she still thinks Zhang Yuan is very powerful, and he has been able to build a hovercar engine while countless of his peers are still fighting in the game, which is really admirable.

Just when the little girl felt that Zhang Yuan was very skilled, Zhang Yuan dialed Lu Yisha's communication: "Hey, are you free now?" ”

Lu Yisha's voice immediately sounded: "Of course I'm free, let's talk, what's the matter?" ”

Zhang Yuan was stunned: "Miss Lu Yisha, you are really a noble person, four days ago, didn't you ask me to build an engine sample, I have completed it now." ”

As soon as he finished speaking, he heard a 'dang long' sound from the communication, as if something had fallen to the ground, and the sound seemed to be a water glass, followed by a violent cough, and after a while, Lu Yisha's voice sounded in the communication: "You mean, you really built the engine?" Don't lie, it's not going to do you any good. ”

As soon as Lu Yisha finished speaking, another female voice sounded in the communication, compared with Lu Yisha's soft voice, this voice seemed crisp and smart: "Your name is Zhang Yuan, right?" Didn't you build the engine? You're waiting at home now, and we'll come and inspect the goods now. ”

"No problem."

Zhang Yuan knew that what he was doing was a bit shocking, this was the huge gap between the starry sky powerhouse and ordinary people, in fact, if you use magical terms, Zhang Yuan is almost a half-god figure now.

On the other side of the communication, Lily stood beside Luisa and snorted: "Build a new engine in 4 days, I'm really a fool, even if he has eight hands, it's useless." Ruisha, wait a minute, see how I poke him. ”

Lu Yisha hesitated a little: "Could it be that he built it before?" Either way, as long as the engine really works. ”

Lily shook her head firmly: "It can't be that he made it before!" I've looked up where this guy came from, and he's just a traveling scholar. I've also checked his recent item purchases, and he didn't have any equipment to build engines before. Therefore, there must be a big problem with the engine he came up with this time. ”

Lu Yisha stopped talking, her best friend was a super top student in school back then, and in the professional field, since she said so, then she could only choose to believe it.

The two left the residence, drove a luxury sports car, and came to the downstairs of the Tianxin apartment where Zhang Yuan lived.

Roisa opened the door and got out of the car first.

As soon as she got out of the car, she was stunned for a moment, and when Lily saw her like this, she asked a little strangely, "What's the matter...... Hey, Zhang Yuan, you're already waiting for us...... This ...... around you Hey? ”

Lily's gaze was fixed on the small pale silver metal block in Zhang Yuan's hand, and the instinct of an engine designer told her that this was an engine, and it was a new engine that Golden Sky had never seen 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 Bai Fumei, graceful and noble, and there was a tomboy-style girl standing next to her, this girl was about the same age as Lu Yisha, with short hair, very delicate facial features, wearing vest and trousers, looking very neat.

He reached out and picked up the engine next to him and walked towards the luxury sports car: "I built the engine, but I don't have the conditions to test it here." Roisa, your company should have a dedicated engine testing site, right? ”

Lu Yisha's eyes kept staring at the pale silver metal block that Zhang Yuan held in her hand at random, and looked at it for half a minute, and then she found that with her professional level, she could no longer judge the authenticity of this engine.

Lily stepped forward directly, carefully looked at the engine Zhang Yuan was holding, she also looked at it for a long time, and then said: "Yes, the shape is very exquisite, it is rare." Zhang Yuan, tell me about its power parameters, can you?"

"Absolutely." Zhang Yuan took this 'iron bump' into the sports car compartment, and after the three of them sat down, he quickly wrote down the parameters of the engine 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 mode is a space force field." Powered by a standard small titanium crystalline battery, it can operate for about 5,232 hours in the ultimate state, with an energy conversion efficiency of about 47%......"

"It can't be!"

Ruisa and Lily shouted at the same time.

Lu Yisha frowned and said: "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 2 meters high, and the maximum output horsepower is less than 20,000, but its volume is more than a thousand times that of the small thing Zhang Yuan took out.

Lily also sneered: "I won't talk about the engine volume, this thing is a little more fine, and it is not impossible to reduce the volume." But at present, the highest energy efficiency of the space force field engine is only about 39%, and the latest and most high-end phantom engine of the Roisa family is at this level, and you will increase it by 8% at this time, which is also too exaggerated! ”

Zhang Yuan threw away the small engine in his hand and said with a smile: "What's the point of you refuting me now?" The engine is there, just take it back and test it,"

Luisa immediately started the sports car, and with a roar of the engine, the sports car flew like a swift cheetah in the fast lane at a height of a thousand meters, all the way towards her family's engine factory.

She now has eight points to believe that what Zhang Yuan said is true, and when things come to this point, there is no point in him deceiving people anymore.

Lily on the side was silent, what happened today exceeded the cognitive limits she had established in the past, and her past only seemed to be unable to be used as a criterion for judgment.

The sports car was speeding all the way, and about half an hour later, the three of them arrived at a professional engine laboratory in the west of White Deer City, and Zhang Yuan then took out the engine and walked to the laboratory.

Lily twitched at the corner of her eyes: "Your engine looks very precise, right, you just hold it like this, aren't you afraid of problems?" ”

Zhang Yuan smiled: "Others estimate that there will be real problems, but I'm fine, even if it's really broken, I can fix it." ”

"Boom!" Lily stopped talking.

On the other side, Luisa had already arranged the test program quickly, and the tester in the laboratory came over, took Zhang Yuan's engine with a strange face, and began to test the engine performance.

Eager to know the results, Luisa waited outside the lab, with Lily and Zhang Yuan herself by her side.

Time passed minute by minute, and about 2 hours later, an old man with gray hair ran out of the laboratory, and as soon as he came out, he looked at Lu Yisha: "Miss, where did you get this engine?" ”

Lu Yisha was full of anticipation: "Uncle Zhang, how is the situation?" ”

There was a deep look of shock in the eyes of the old man who was called Uncle Zhang: "This is a perfect space force field engine, the energy conversion efficiency is as high as 47.3%, the power output is very stable, after stabilizing at the limit, the surface temperature of the engine has been maintained at a low temperature of 321 degrees, and the noise has been below 10 decibels when it is running." What's even more rare is that it is so small...... Oh my God, it's a miracle, it's like an artifact made by the gods! ”

"Goo Dong~" A voice came from beside her, it was Lily, she stumbled and knocked on the chair on the side. This thing is completely beyond her cognition, how can a person, four days, build such an excellent engine, is this guy still human?

Lu Yisha's heart was a burst of ecstasy, she was a businessman first, and she would not bother Zhang Yuan with how to build an engine, she only knew now that the new technology contained in this engine could improve the competitiveness of the group to the point where others could not reach it!

She turned around sharply, as if she was afraid that Zhang Yuan would run away: "Mr. Zhang, we need to have a good talk!" ”
