Come to the old man's house.

As soon as Tang Rui entered the house, he saw a large family of people busy working.

His mother-in-law and brother-in-law's wife were cooking in the kitchen, and his father-in-law, brother-in-law and Li Shuyao were chatting with his grandmother.

Tang Rui entered the house, and after saying hello to everyone, he was pulled to the study by Li Shuyao.

"Grandpa, Tang Rui is here, you can tell me directly if you have anything."

After coming to the study, Li Shuyao ran to the old man's side and said with a smile.

"You go out first, and I'll talk to Xiao Rui myself." The old man was ruthless, and he was going to drive Li Shuyao out.

"I can't listen yet?" Li Shuyao's eyes widened and she looked at her grandfather in disbelief.

This is the legendary unloading and killing of donkeys?

"You definitely can't listen to it, what we want to talk about is a state secret." The old man drove Li Shuyao out of the study without compromise.

The corners of Tang Rui's mouth also twitched.

In fact, Li Shuyao's secrecy level is not as low as the old man thought, after all, with him, the secrecy level cannot be low.

"Xiao Rui, delay for a while, help the old man and I see a drawing." After the old man locked the door, he said to Tang Rui.

"What's the delay, it's all a family, I'm embarrassed to come here if you keep doing this." Tang Rui hurriedly waved his hand and said.

"Okay, then I won't talk about it, you can take a look at this first."

The old man took out a design drawing, spread it on the table, and asked Tang Rui to help take a look.

Li Shuyao's grandfather, when he was young, was engaged in marine research, and was later transferred by the Navy to help, and worked in the Navy's research institute until he retired.

The drawings he took out, Tang Rui thought it was some kind of diving equipment or drawings of underwater robots.

As a result, there were several big words written on the drawing.

New type of battleship.

Boy.

This is the awakening of the Navy's giant ship artillery doctrine, to build a battleship, and experience the roar of multiple turrets.

But when he saw the design of the new battleship on the drawings, he found that things were completely different from what he had thought.

It's a battleship, that's right.

But this battleship did not sail in the sea, but in the sea of stars.

Acute triangle design, three 1024 mm caliber main guns, 24 680 mm secondary guns, equipped with three nuclear fusion reactors, using 16 large electric propulsion engines.

After reading the drawings, Tang Rui didn't know what to say.

"Xiao Rui, can this battleship be built?"

“…… Let's not talk about the question of whether it can be built or not, I want to ask, where did this drawing come from? ”

Tang Rui didn't understand where the old man got this kind of god-like drawing.

"Haven't I been rehired, I usually don't have anything to do, just mess with the other people in the institute.

Having a problem with this drawing? Is there something that hasn't been designed well? When the old man said it, it was obvious that his mouth was wrong.

"No, it's well designed, but it can't be built." Tang Rui saw it, but he didn't care.

Did he build this battleship?

Made.

But even if it's made, it's still a good thing.

"Can't make it? Is it a device issue, or something else? ”

"It's okay to build these devices, they can be built, but even if they are built, they can't be lifted into the air."

Tang Rui didn't fool the old man, he was telling the truth.

Electromagnetic anti-gravity has a limit.

Just like the buoyancy of water, the limit of electromagnetic antigravity is related to the strength of the planet's magnetic field.

With the strength of the Earth's magnetic field, the limit of the weight that can be lifted by electromagnetic antigravity is 5,176 tons.

It doesn't matter how many SEG units you use.

Even if you stack them, it doesn't make any sense.

Of course.

The strength of the earth's surface magnetic field can be enhanced by other means, such as making a huge coil to increase the repulsion.

But the problem is, this kind of thing is not practical.

And the scope of influence is still limited, flying to an altitude of 20,000 or 30,000 meters, you can't fly, how embarrassing.

Therefore, unless Tang Rui points out the real anti-gravity technology, it is impossible to achieve this type of spaceship, even if it can fly to outer space, it is meaningless, because there is no gravity inside the spacecraft.

Could it be that all the soldiers are floating in the battleship?

That's not a joke.

Without gravity for a long time, calcium loss can be very severe.

What is the use of building this kind of spaceship that looks awesome, but can't even fly out of the solar system.

As for flying within the solar system.

Wouldn't it be nice to build a spaceship that simulates gravity with centrifugal force?

"Then if you want to build a battleship, how do you need to modify it?" The old man nodded after hearing this, and continued to ask.

"Revision...... Just change it to this. ”

Tang Rui took out his mobile phone and took out the renderings of the Queqiao space station designed by Red Lotus before, and let the old man take a look.

"This is a space station, not a ship."

"There's no way, the current technology can only be done like this at most, like the kind of space battleship in the movie, it really can't be built."

"I'll just say, I can't make it, it's not those old guys who are pulling me, and I have to design some cross-era weapons."

Put away the drawings and put them back away.

The old man took Tang Rui out of the study.

At this time, the meal is also ready.

Everyone began to eat at the table.

"What did Grandpa say to you just now?" Li Shuyao asked Tang Rui in a low voice.

"It's nothing, I'll tell you when I get home."

Tang Rui shook his head and didn't tell her.

"Brother-in-law, what do you want to drink? White or red? The eldest brother took two bottles of wine and asked Tang Rui's opinion.

"I can do it all." Tang Rui doesn't care.

Anyway, everyone drinks about the same amount of alcohol, and everything they drink is the same.

One meal was eaten for more than two hours.

It was not until about nine o'clock in the evening that they left the old man's house.

Tang Rui was also dazed.

"What's the matter with Grandpa?" After getting in the car, Li Shuyao asked again.

"The old man told me one thing, some people want to go big, want to climb to the sky in one step."

Although Tang Rui had drunk, his mind was still sober.

Today's old man's problem is obviously that the drunkard does not mean to drink, but to tell him something through the design of the battleship.

"Does it affect you?" Li Shuyao asked worriedly.

"What impact can it have on me, if it does, I still need to hire the old man back, and then make such a big turn?"

Tang Rui didn't take it seriously at all, it was obvious that the old man was thinking too much.

The next day.

He came to Han Shu.

"Mr. Tang, you're finally free." After Han Shu saw Tang Rui, his resentment was almost written on his face.

"I've been busy lately, so I didn't come to you just after I was done." Tang Rui grabbed a handful of melon seeds and said while snorting.

"There is good news, I made a report before, and the above has increased the funds for our Blues to purchase equipment." When Han Shu talked about the funds, he was still a little excited.

It seems that this should be a lot of money.

"How much?" Tang Rui asked curiously.

"120 billion." Han Shu replied immediately.

Well?

120 billion.

After Tang Rui heard this number, his expression was a little weird.

"How? Not enough money? ”

"No, didn't it say what equipment the money was used to procure it?"

"No, it said that let me discuss with you, it's best not to use traditional weapons, but to match the equipment of the new era."

"Do you want a mech?"

"The kind of mecha that opened the peerless in Tifa? How much? ”

"120 billion."

“……”

The above appropriation must have an idea, and it deliberately asked for new equipment, which is not what a mecha is.

And this price is exactly the cost price of the mecha.

"Bought it."

Han Shu gritted his teeth and spoke.

"Not for sale." Tang Rui directly refused.

"Mr. Tang, let's stop joking."

"The mecha is definitely not for sale, that is a technical verification machine, and it hasn't met my requirements yet, but with this money, we can build a big toy."

"What big toy?"

"What about the battleship, you say?"

Tang Rui said the purpose of his coming here today.

"Battleship? You mean electromagnetic gun battleships? After Han Shu listened, he thought about it and said.

"Be bold."

"Space-to-air battleships?" Han Shu's eyes lit up and said.

"Be bolder."

“…… Could it be a space battleship? ”

I caught a cold, I took cold medicine and became sleepy, and this chapter was written for more than four hours, and my brain was really not good.

The debt owed will be made up tomorrow, get up early tomorrow, start coding words in the morning, and sleep with a small cold will be almost nothing.
