It's reasonable for me to have a two-way foil for a second-level civilization, right?

Chapter 221 Electromagnetic Coil Gun

"Professor, the stability of the electromagnetic coil gun..."

A trace of worry flashed in Yevgeny's eyes, and he said to Lu Yongchang: "Interstellar warfare requires extremely high precision."

"Even if there is a slight change in the direction of projectile launch, it will cause a huge error in the end!"

Lu Yongchang nodded.

He naturally knows this, which is why he chose the electromagnetic railgun in the first place.

There is a huge difference between a small loss and a thousand miles. This sentence is perfectly suitable to describe the interstellar war.

Even a deviation of one micron will cause an error of tens or even hundreds of kilometers!

After all, unlike missiles, electromagnetic guns can adjust their direction in real time.

In space, there are no unusual conditions for a projectile to travel in a straight line.

Lu Yongchang pondered for a moment, then turned to Ling and asked, "Ling, can you complete this part of the work?"

"..."

After a short wait, Zero responded in a flat voice: "Professor, there is not enough experimental data to make a judgment."

"I need a lot of experimental data to refine the algorithm."

Lu Yongchang nodded thoughtfully.

If there is no direct veto, it seems that there is still something to do!

……

2037.7

Two months after the starship weapon system research and development project was established.

A gun barrel with a length of more than 30 meters and a diameter of 1.2 meters lay quietly in the factory in Mars City.

Next to the barrel, there is a huge base and various parts.

Lu Yongchang stood beside the barrel, stretching out his hand to gently brush the cold barrel, his eyes showed a bit of emotion.

"Professor." Yevgeny's excited voice came from the side, "When shall we test its power?"

Unlike Lu Yongchang, Yevgeny had only one idea about this giant cannon at this time - when can he fire a cannon to try the effect!

Lu Yongchang turned his head to look at Yevgeny, whose face was full of excitement, and shook his head with black lines: "What are you thinking?"

"This big guy sure can't be launched on Mars!"

Not to mention its extremely exaggerated recoil, even its abnormal demand for energy can instantly drain the fusion reactor of Mars City.

In addition, it is the extremely exaggerated power of the shells.

Electromagnetic coil guns have higher energy efficiency than electromagnetic rail guns.

Thanks to this, in the simulation calculation, the initial velocity of the projectile reached 6000 km/s!

With a shell speed of 6000 km/s, once any accident occurs, Mars City will not be able to withstand such a blow!

For the sake of safety, the best way is to temporarily transform a Luanniao starship, install it on the Luanniao-[-] starship, and conduct a test launch in space.

"...Okay." A look of disappointment flashed across Yevgeny's face, and he nodded slightly.

Lu Yongchang looked at the unassembled electromagnetic coil gun in front of him, and the experimental prototype in the laboratory some time ago appeared in his mind.

It is also an electromagnetic coil gun, but as a prototype, it is not very powerful, and the speed of the shell only reaches 10 km/s.

Its main function is to provide sufficient experimental data samples for Zero, so as to improve Zero's algorithm.

Through that prototype, Lu Yongchang discovered a problem.

"The power is too weak..."

Lu Yongchang stared at the gun barrel in front of him, muttering to himself.

"What?" Yevgeny on the side looked at Lu Yongchang in horror, "The 6000 km/s shell is not powerful enough?!"

"No, I'm not saying that a single shell is not powerful enough." Lu Yongchang was stunned, then shook his head and explained.

"I mean the weapon isn't powerful enough in Star Wars."

6000 km/s, a metal projectile with a diameter of one meter, Lu Yongchang believes that even if it is a second-level civilization, there are not many starship armors that can block this shell.

For starships that are hundreds of meters or even thousands of meters away, unless they hit a key part, this small injury will not affect the battle situation at all.

Unless...it was really as he had expected, with a metal storm saturation attack.

However, in this way, the cost of a war may exceed his imagination.

At that time, human beings are just a wandering civilization. After traveling 4.22 light years, can they really have so many ammunition reserves?

Even if there is, such an attack method will only be used at critical moments.

Who started the fight against the landlord and went straight to the king? !

Lu Yongchang sighed slightly, and briefly shared his concerns with Yevgeny.

"Snapped!"

Yevgeny patted his thigh hard and looked at Lu Yongchang excitedly.

"Professor, you should have said it earlier!"

"I have an immature idea, would you like to listen to it?"

Lu Yongchang looked suspiciously at Yevgeny in front of him, thought for a while, and asked tentatively, "You... tell me?"

The excitement in Yevgeny's eyes grew stronger after he got permission, and he said cheerfully, "Professor, I think so."

"Since you think the power is not strong enough, how about we directly transform these projectiles into small nuclear bombs?"

"Currently our technology should be able to do this!"

"..."

Inside the factory, everything was quiet.

Lu Yongchang looked at Yevgeny next to him in disbelief.

Can everything be nuclear?

However, after thinking about the incidents in which Su used nuclear bombs to extinguish fires and hydrogen bombs to eliminate nuclear pollution, Lu Yongchang suddenly felt that everything made sense again.

The corner of his mouth twitched slightly: "Professor Yevgeny, the explosion power of nuclear bombs in space is not as powerful as that on earth, you should know this."

Yevgeny didn't care about Lu Yongchang's objection at all, and moved his upper and lower lips quickly, continuing to speak at a very fast speed.

"Professor, we don't need that so-called shock wave to cause damage!"

"Don't forget that fragments from projectile explosions can also do damage."

"In addition, there is nuclear radiation and electromagnetic pulse when the nuclear bomb explodes!"

Lu Yongchang's eyes showed a bit of emotion.

Needless to say, he was moved.

"Cough!" He coughed hard, and said with an unnatural expression, "This...let me verify it. If possible, we can manufacture a batch of projectiles containing miniature nuclear bombs."

Yevgeny's urgent voice sounded: "Professor, don't worry, I have verified it with zero!"

As he spoke, Yevgeny pressed the watch on his hand.

A holographic projection appeared in front of Lu Yongchang.

Looking at the detailed calculation process and simulation screen above, Lu Yongchang's eyes twitched again.

Good guy, this is prepared!

"Zero." Lu Yongchang turned his head and said to the camera on the side, "How is the working status of the mining robots on the earth?"

Zero's avatar appeared on the side.

"Professor, due to the impact of the environment, only a small half of the mining robots are still working."

“[Tower of Babel] is no longer operational, but [Jianmu] can still operate normally.”

Lu Yongchang's expression turned serious.

"Let those mining robots go all out to mine uranium!"

Chapter 222 Asteroid Strikes

the next day.

After verifying the feasibility of a series of projectiles, Lu Yongchang heard a yawn from the side.

He turned his head and saw Yevgeny looking at the holographic image in front of him with a tired face, opening his mouth and yawning from time to time.

The excitement of the previous two days has disappeared without a trace.

It's normal.

In order to verify these projectiles, the two basically did not sleep all night.

As a player who stays up all night and explodes his liver all the time, Lu Yongchang naturally doesn't feel much, but Professor Yevgeny on the side obviously hasn't adapted to such a life.

Lv Yongchang chuckled, stretched out his hand and waved, dispelling all the holographic projections made by Zero.

Suddenly seeing the holographic image in front of him disappear, Yevgeny couldn't help being stunned, and turned his head to cast a puzzled look at Lu Yongchang.

"professor?"

"Let's rest first." With a smile in his eyes, Lu Yongchang reached out and patted Yevgeny's shoulder, "The main plan has been released, and the specific verification can be done slowly."

Before Yevgeny nodded, a bright red holographic image appeared beside them.

【alarm】

At the same time, Zero's voice rang through the speakers.

"Professor, we are in trouble."

……

Mars City No. [-], the main meeting room.

A member of parliament is sitting on the left side of the conference table.

On the right side of the conference table, several high-level officials of the Academy of Sciences were sitting.

Everyone stared solemnly at the holographic image in front of them.

"Professor, is this true?"

Fang Xu's uneasy voice sounded from the side: "How could it be such a coincidence?"

Faced with Fang Xu's doubts, Lu Yongchang sighed slightly, lowered his eyes and sighed: "According to Zero's deduction, this is because of our mining activities in the asteroid belt, coupled with changes in the sun..."

"It's a whole series of butterfly effects that lead to it happening."

In the holographic simulation image, an asteroid with an irregular shape is flying in endless space.

The trajectory slowly appeared, and the destination was the fourth planet in the solar system—Mars!

"Yongchang, have you verified it?" The old voice of the chairman came from across the conference table.

Lu Yongchang raised his head and looked at the old man.

The old man's old face was very calm, but there was a bit of uneasiness and doubt in his slightly cloudy eyes.

Lu Yongchang nodded silently.

"Zero has been verified more than 2000 times. If there is no unexpected situation, this asteroid with a diameter of 100 kilometers will directly collide with Mars!"

"In order to prevent observation errors, we have sent Hummingbird 1, a mining mission in the asteroid belt, to verify it. It is estimated that specific information will be sent in a short time."

As soon as the words fell, Zero's voice sounded in the meeting room.

"Professor, there is a communication request from Hummingbird 1, is it connected?"

Lu Yongchang took a deep breath and said in a deep voice, "Connect!"

……

a few hours ago.
