moving city, ark

Moreover, even if not every day, there are always a few days every week~

With a happy smile, he took the initiative to take the two cups of the same coffee from the hands of the waiter who seemed a little flattered.

Suddenly a strange thought flashed through his head.

Cardcaptor Sakura?

"puff."

"—?"

Kelsey looked strangely at Luo Yi who suddenly laughed, and reached out to pick up his coffee cup expressionlessly, "There are no couple models, so do it yourself."

"Ah, yes, yes. I will suggest this store next time."

"..."

All in all, this time belonged to the two of them, and the short dating time was ended satisfactorily.

After drinking the coffee, the two went straight to the elevator leading to the palace.

However, he is full of expectations for tomorrow.

Rather, I am full of anticipation for the next day.

"Hey, by the way, what day is it today?"

The two walked into the gate of the palace under the surprised sight and welcome of the maid at the gate of the palace.

"Friday, what's the matter?"

"Hmm... let me see..."

Luo Yi, who opened one screen, flipped through it, and suddenly leaned towards her with a smile, while placing the screen at hand in front of her.

It is the schedule of the palace.night edition.

"It's tonight~?"

"..."

"I know."

She replied blankly.

As a person, of course she knows this kind of thing.

"Well...then I'll put these clothes in your closet for you~ By the way, let's choose tomorrow's outfit first, so as not to waste time in the morning~"

"..."

She finally couldn't hold back a sigh.

"As you like."

Chapter 370 The Last Puzzle of Xinggang

In the afternoon, Luo Yi's studio.

"What good thing happened to you?"

Looking at Luo Yi who was humming a little tune in front of him with a smile on his face all the time, Nian couldn't help but complain.

"Huh? It's really a good thing."

"Hey, let me reveal it?"

"It's none of your business."

He reached out and pushed the dragon's head away, picked up the eyepiece on the table and hung it on his ear.

"How do you know it's okay if you don't tell me?"

He didn't seem to care at all, Nian who was pushed away by him sat sideways on a corner of the table, his tail swung behind him, one leg under the hot pants was bent and rested on the table, and the other leg was pointing to the floor in an eye-catching curve.

"personal privacy."

He withdrew his gaze, turned around and walked towards the corridor inside the studio, raising his arms and beckoning back.

"Hey, it doesn't make sense for you to say that."

Nian jumped off the table and followed Luo Yi's footsteps.

"You're a little girl who hasn't even experienced a bridal chamber, so it wouldn't be interesting to tell you?"

"Oh, it's really you who actually called me a little girl. Does it sound like you've been in a bridal chamber?"

Tsk, seriously, it seems that there really isn't one.After all, the wedding hasn't even happened yet.

but,

"You can't understand the fun of men."

He pouted.

"Huh? To put it bluntly, it's those things. Don't forget that you were still learning from me before. Could it be that you have improved recently?"

Nian showed an ambiguous smile and poked his waist with his elbow.

"Hey—it seems that he has a lot of strength."

The corner of his mouth twitched, and he raised his hand and slapped the elbows around his waist away.

"What the hell are you doing?"

Because some of the secrets in him were originally learned from Nian, so he was easily mobilized by the other party.

However, this type of secret biography can not be used in any occasion!

"Oh, why are you so shy~"

As a result, the smile on the other party's face became even brighter, and he stretched out his fingers to poke his abdominal muscles again, "It's not like I haven't seen these parts of your body before, do you want to review your homework with the teacher?" , let the teacher continue to teach and teach?"

"..."

He has always been the only one who teases cute girls, but unexpectedly he will meet a female hooligan one day.

His gaze unconsciously passed over Mr. Nian's well-defined and coolly dressed belly.

"I have already become a teacher. If you want to teach, I don't know who is teaching whom—a teacher who has never practiced before."

He pouted.

"Hey, learn from each other?"

"..."

He looked at Nian with a straight chest under the red tube top embroidered with gold, and the corner of his mouth twitched, "Forget it, I admit defeat."

"You're smart, my boy~"

"..."

I'm so angry!

This guy.

Staring at the smiling Nian in front of him, he couldn't help grinding his teeth.

If it wasn't for him being unable to fight... Forget it, the more I think about it, the more angry I get.

Although it's just a fragment of a god, unless he really gets serious and fights, it's really impossible to break arms with Nian, and some actions to seize the initiative can only be ridiculed in turn.

He has always been on the side of shaking S, even if he is not prepared to take some substantive actions, it is impossible to just accept it like this.

But this is not overwhelmed...

suppressed in all directions.

Realizing this, Luo Yi could only force himself to look away from Nian's smiling face and focus on the workroom in front of him.

"Stop talking, it's time to get down to business."

"Okay~ Ah, speaking of which, haven't you told me what good things happened to you?"

"...A date with Kelsey."

"that's it?"

"You don't understand what's behind."

"Hey!"

Without continuing to quarrel with Nian, Luo Yi, who walked into the room, set his sights on the assembly table in the center of the room, which already had a rough prototype.

an engine.

Electric propulsion engines, to be precise.

As mentioned before, the construction of the star port is one aspect. However, in addition to this, if there is a port, of course it must be equipped with corresponding ships.

Under the condition that materials, energy sources, and computing cores are all complete, the last piece of the puzzle is now in front of his eyes.

Spaceship engine.

There is no deviation from the original expectation, and his choice is also the Hall thruster with the most possibility and potential among electric propulsion engines.

In short, the principle is to form plasma through Hall current and propellant gas, accelerate and eject at high speed under the action of magnetic field, thereby generating thrust.

The electric field force and magnetic field force involved in it can be said to be a wrestling between Coulomb force and Lorentz force, which should be very familiar to science high school students in China.Of course he is no exception.

The biggest limitation of the Hall engine has always been in terms of total power and total impulse. Some smaller electric propulsion engines can only push two A4 papers.

However, once the power problem is solved, the specific impulse of the Hall thruster can even reach ten times that of the chemical working medium engine, and the fuel consumption can be reduced by ten times.

For a spaceship equipped with an Ark reactor, it is undoubtedly the best choice.

Of course, the premise is that he solves the problem in front of him.

"Is the discharge room done?"

"Phew—it's a piece of cake!"

"Once it's done, quickly bring it and install it."

"I know, I know."

"..."

The two people in the workshop gathered around the assembly table and the quietly placed engine, and the intense busyness had lasted for nearly three hours.

It is slightly different from the modern technology on Earth. As long as it is a technological product manufactured in Terra, it must not bypass the special item of open source stone.

Fortunately, he has been familiar with Originium technology for such a long time, and it is not difficult to see his purpose through Originium technology.

Some troublesome problems may be solved in front of Originium Technology, but at the same time, it may also cause some new problems.

For example, the erosion of materials by Originium particles, energy stability under high power, and so on.

The Hall thruster before them? The biggest problem is that while the power is increased, the electron beam formed by the Hall current collides violently with the propellant in the discharge chamber to form a plasma, which affects the main body of the discharge chamber. Materials form extremely high demand.

Originally, Luo Yi was still preparing a research plan for special-type new materials, but after the arrival of Teacher Nian—the god who is best at smelting and casting—with the help of Nian, his research has progressed so far. The most beneficial is the field of materials.

Even the casing of the engine was not prepared, and the exposed wiring and internal structure were exposed to the air. Luo Yi heaved a sigh of relief, wiped the sweat from his forehead, and took out the fuel for the engine from the side.

— a xenon rod.

第 664

Chapter 370

Unlike the heavy fuel tanks of chemical thrusters, the xenon rods that Luo Yi took out were only about the size of an adult's forearm and weighed just over 10kg.

Compared with the one-meter-long propeller on the assembly table, it looks quite small.

Connecting the xenon rod in his hand to the thruster, Luo Yi took a deep breath, looked up at Nian who gave the thumbs up, and reached out to press the power switch.

"Buzzing—"
