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

After a moment of silence, Lu Yongchang suppressed the shock in his heart and said "lightly".

Hearing this, Zhao Zijie swallowed again.

Is the power okay?

This is also called okay? !

Zhao Zijie muttered to himself, if this weapon had been released a few years earlier, the unification of mankind would have been realized long ago.

"By the way, Professor Lu, what about those projectiles that missed their targets?" Gao Yang seemed to realize something, and suddenly asked, "Don't you need to deal with it?"

"Deal with it? How do you think we should deal with it?" Lu Yongchang's slightly weird voice came from the side, "Are you going to chase it?"

Gao Yang: "..."

Seeing Gao Yang and Zhao Zijie's speechless faces, Lu Yongchang shook his head with a smile, and suddenly asked: "Ling, where did those bullets fly just now?"

"..."

After a brief silence, Zero's voice sounded again, "Professor, according to calculations, most projectiles are flying in the direction of Proxima Centauri."

The voice fell, and the cockpit fell into silence.

Proxima Centauri?

Zhao Zijie turned his head and looked at Gao Yang, swallowed and said in a low voice, "Professor, this...should be all right?"

In the holographic screen, Lu Yongchang shook his head with a strange expression, and said hesitantly, "No, it's okay."

"The difference is a thousand miles away, and the distance of 4.22 light years is enough to magnify the error infinitely."

"Not to mention the various disturbances that may exist on the way, the probability that these projectiles will just arrive at Proxima Centauri is also very low."

"What's more...according to the speed of these projectiles, it will take more than 200 years to reach Proxima Centauri. At least for now, we don't need to worry about it."

Zhao Zijie and Gao Yang nodded silently.

Since Professor Lu said it's okay, let's pretend it's okay.

Anyway, the shells have already flown over, and they can't intercept those projectiles now.

If humans haven't reached Proxima Centauri after 200 years, then these projectiles should be the first batch of "gifts" to neighbors.

"Ahem!" Lu Yongchang coughed lightly, attracting the attention of the two of them.

"Okay, the interception mission has been completed, Captain Zhao Zijie, you can return to the voyage!"

As soon as the voice fell, Lu Yongchang cut off the communication directly.

Seeing that the control of the starship returned to him, Zhao Zijie silently pressed a few buttons.

In the deep universe, this strangely shaped starship slowly turned its direction and headed towards Mars.

……

Inside the Mars spaceport.

Lu Yongchang and Fang Xu looked at each other.

"..."

After a long silence.

"Yongchang." Fang Xu broke the silence, "Those bullets..."

Facing Fang Xu's question, Lu Yongchang smiled wryly, spread his hands and said, "Don't ask me, I don't know either."

"Even zero can't answer this question."

"Not to mention the distance between the solar system and the neighboring galaxy, there are countless variables in this solar system."

"Ghost knows where these projectiles end up flying..."

Hearing this "unreliable" answer, Fang Xu also had a wry smile on his face.

"However, in my opinion, we don't need to worry too much about this issue." Lu Yongchang shrugged and said in a very indifferent tone, "Since human beings are already ready for war, there is no need to worry about this issue." What is the effect of the so-called projectile?"

"If we're fast enough, we might still encounter these projectiles on the road."

The wry smile on Fang Xu's face became stronger: "That's true."

"The electromagnetic gun technology has been overcome, what are you going to do next?"

"laser weapon?"

Lu Yongchang thought for a moment, then nodded in affirmation of Fang Xu's statement.

"Laser weapons are essential."

"The speed of the electromagnetic gun is still a bit slow. For long-distance targets, it is more difficult to strike."

Fang Xu stood up from his chair and said with a smile, "Okay, it's up to you to develop weapons."

"I have to go to Cao Liangcai's side."

"After resting for such a long time, I reckon that Lao Cao is already scolding me behind my back."

Lu Yongchang's expression changed slightly: "What? Did Lao Cao encounter difficulties?"

"I remember they should be developing a new type of starship, right?"

Fang Xu nodded.

"Correct."

"At present, Lao Cao and the others are still struggling with the structure of the new starship."

"After the types of starships began to be subdivided, the workload of Lao Cao and the others naturally increased a lot."

There was some emotion in Lu Yongchang's eyes: "There is no other way."

"Everything we do is for the future of interstellar navigation and warfare."

"Starship manufacturing is even more important."

"Naturally, we can't cram all functions into a starship like before."

"Come on, don't forget, there are still 38 billion humans waiting for us in the Kuiper belt!"

Fang Xu's face suddenly became serious, and he nodded vigorously: "Don't worry."

While talking, the two came to the [Xunmu] space elevator.

"Ding!"

With a clear reminder, the door of [Xunmu] slowly opened.

"correct."

The moment he stepped into the door of the space elevator, Lu Yongchang suddenly said, "Remember to tell Lao Cao."

"Let him not forget the chicken leg meal he owes me."

There was a flash of astonishment in Fang Xu's eyes, and then he laughed and nodded: "Okay! I will definitely convey it!"

Chapter 227 Defects of Laser Weapons

Mars City No. [-].

Laser weapon research and development laboratory.

"Professor Wilson." Lu Yongchang's voice came from a distance from the door, "How is the research going?"

Wilson's eyes lit up when he heard the voice, he quickly stood up from his seat, and walked towards the gate.

"professor."

Seeing Lu Yongchang in a white coat walking towards him, Wilson lowered his head slightly and greeted him in a respectful tone.

"Is the electromagnetic gun test over? How effective is it?"

Seeing the reluctance in Wilson's eyes, Lu Yongchang smiled: "The effect is very good! The initial velocity of the projectile has reached 6000 km/s!"

"According to Yevgeny's suggestion, we have added a miniature nuclear bomb to the electromagnetic gun projectile, and the power of the projectile has greatly increased!"

"An asteroid with a diameter of 1 kilometers turned into powder within [-] minute."

Wilson couldn't help but froze on the spot, his eyes flickered, and he muttered to himself, "This... is this electromagnetic gun so powerful?"

At this moment, the image of Yevgeny showing off in front of him even appeared in Wilson's mind.

"What about you? How powerful is the laser weapon?"

Lu Yongchang's voice interrupted Wilson's "daydream".

"Professor, I'm going to find you." Wilson said with embarrassment in his eyes, "We have already made a laser weapon, but..."

Lu Yongchang showed a bit of joy: "There are already results? Take me to see it!"

With that said, Lu Yongchang walked directly towards the laboratory.

Wilson quickly followed Lu Yongchang: "Professor Lu, the effective attack distance of our laser weapons is only about [-] kilometers."

"Once it exceeds [-] kilometers, the power of laser weapons will rapidly decay."

"Besides, in order to increase the power of the laser, we..."

"Damn it!" Lu Yongchang's soul-stirring exclamation sounded in the laboratory, "So big?!"

"...We adjusted the size of the laser emitter a little bit," Wilson added in a low voice.

Lu Yongchang stared blankly at the laser emitters that occupied most of the laboratory: "You call this a slight adjustment?"

"The radius of this laser transmitter must be 10m?"

"...To be precise, it is 9.5 meters." Wilson said cautiously, "Professor Lu, despite its size, its power is also great!"

Lu Yongchang sighed deeply.

Those who make weapons are more "unreliable" than the other.

The former only has nuclear bombs in his mind, while the latter keeps trying to "make it bigger and stronger".

"for example?"

Hearing this, Wilson immediately became excited!

"Professor, according to our tests, even the armor of the Luanniao starship can't last a second in front of it."

Lu Yongchang was stunned.

He looked up again at the disc-shaped laser lens with a radius of 9.5 meters in front of him.

He suddenly discovered that the huge disc in front of him seemed much more pleasing to the eye.

"Cough cough!" Lu Yongchang coughed twice, moved closer to Wilson, and asked in a low voice, "Can the power be enhanced?"

Wilson: "???"

"You know, we are going to face a doomed interstellar war. The range of [-] kilometers is still a bit short to me." Lu Yongchang straightened his expression and continued, "Besides, without knowing the thickness of the enemy ship's armor and the In the case of insufficient strength, we can only increase the power of the weapon as much as possible."

"What do you think, Professor Wilson?"

Wilson suddenly came back to his senses: "Professor Lu, I think you are right!"

"It's just... a matter of range, this is already the highest power we can support at present."

Lu Yongchang frowned: "Is there a problem with the fusion reactor?"

"Not all." Wilson's eyes showed a bit of bitterness, "The main problem is heat dissipation."

"Professor, you also know that it is difficult to dissipate heat in space."

"We can only actively dissipate heat through a large amount of coolant, so the current laser weapon is the limit of what we can do."

Seeing Lu Yongchang's slightly disappointed expression, Wilson gritted his teeth and said again: "Besides, due to the heat dissipation problem, in actual combat, the effect of laser weapons may not be as good as you imagined."

"In order to increase the power and reduce the heat dissipation pressure, we specially designed this laser weapon as a pulse type."

"That is, it doesn't last forever."

Lu Yongchang's face became more and more ugly.

This is undoubtedly bad news.

Unable to continue to illuminate, this means that the threat of this laser weapon to enemy ships is not even as great as that of electromagnetic guns!

"Then what's the use of this laser weapon?" Lu Yongchang shook his head in disappointment.
