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

In just 15 seconds, they can completely destroy an 800-meter Luanniao starship!

Although there will not be such a perfect output environment in a real interstellar war, this terrifying firepower has brought enough confidence to Lu Yongchang!

"it is good!"

Lu Yongchang breathed slightly short of breath, and said in a deep voice: "Zero, pack up this information and pass it on to the chairman of the council, so that the old man will be happy too!"

"Okay, Professor."

Zero was as calm as ever.

After the weapon system test was completed, the holographic image in front of him gradually dimmed, and the transformed ostrich at the side also slowly turned its direction and drove towards the space port.

Everything came to an end, only the dilapidated Luanniao I starship in the distance, which was almost broken into dregs, slowly drifted away from Mars, as if telling the tragedy that happened just now.

"Professor." Wilson's voice sounded from the side.

"Huh?" Hearing the call with a little trill, Lu Yongchang was stunned, and turned to look at Wilson beside him.

Wilson's complexion was slightly pale, and his eyes were full of complex emotions mixed with excitement and fear.

"Professor Wilson?" Lu Yongchang frowned slightly and called softly.

"Professor." Wilson swallowed hard, "Since we can destroy a Luanniao starship within ten seconds, then you say, the Proxima civilization, will they also be able to..."

Lu Yongchang fell into silence.

After a long time, he sighed softly: "Although I really don't want to admit it, there is a high probability that the Proxima civilization also has such strength."

"Moreover, they also have the advantage of fighting locally."

"I know what you want to say." Lu Yongchang sat back in his chair with a complicated expression, "Defensive technology, right?"

Wilson nodded repeatedly.

Lu Yongchang sighed again.

Memories of the past few days slowly emerged in his mind.

When the high-energy ion beam technology made a breakthrough, he realized the problem of weak defense.

So he entered the technology tree space again, trying to find a higher level of technology.

He searched the technology tree of the first-level civilization, but he couldn't find a defensive technology that could be used.

Although he didn't get any gains in defensive technology, he did have additional gains in other areas.

Because the research and development of ion beam weapons has been completed, the dim cursor on the left side of the technology tree gradually brightens.

[The prototype of energy weapons: preliminary mastery of ion beam weapons]

Afterwards, white spots of light spread upwards, reaching straight towards the weapon that symbolized the second-level civilization.

[Initial Mastery of Energy Weapons: Plasma Weapons]

At that time he was moved!

After all, who would think that their firepower is not enough?

There is a saying that offense is the best defense, as long as he wipes out the Proxima fleet first, the human fleet will not be harmed!

So, he once again focused his attention on the cursor of the second-level civilization.

And then... no more.

The severe dizziness directly kicked him out of the technology tree space.

Fortunately, he was not in a coma, otherwise, he would have to face Dr. Wen's strange eyes again...

Lu Yongchang shook his head, put aside the distracting thoughts in his mind, and said in a deep voice.

"Professor Wilson, it is very difficult for us to realize such a technology in a short period of time."

"Let's talk about the electromagnetic gun first."

"In the face of such a powerful metal storm, even if we use the best materials to construct the shell of the starship, we cannot stop its attack."

"Let's talk about the ion beam. The defense method is likely to deflect it with the help of a magnetic field, but we have no way to create a stable magnetic field shield around the starship."

"As for the lasers..."

Speaking of this, Lu Yongchang had a bitter smile on his face.

There was some confusion in Wilson's eyes: "Then, then we..."

Lu Yongchang reached out and patted Wilson on the shoulder: "Relax."

"Although we don't have defense technology, but thinking about it better, there is a high probability that the Proxima civilization is like us, and it is a crispy skin with high attack power."

Wilson smiled wryly and shook his head: "So, this interstellar war is actually a weapon range?"

"..."

Lu Yongchang nodded with a strange expression: "It's not wrong if you want to say that."

"In addition to the range of weapons, the rest mainly depends on the maneuverability of the starship and on-site command."

"Of course, if we make the starship big enough, we may be able to solve this problem."

Wilson: "..."

Armor is not enough to stack blood bars, is it?

Chapter 235 Minimalist Plasma Weapon

"Cough! Just take this plan as a joke."

Facing Wilson's strange eyes, Lu Yongchang said with a smile.

Let's not talk about whether the current material strength can support the so-called planetary fortress.

It is the extremely huge weight and volume that doomed this to be an unrealistic idea.

At least, for low-level civilizations, this is a plan that is absolutely impossible to complete.

"The experiment is over, and we should go." While talking, Lu Yongchang untied the magnetic buckle between the space suit and the chair.

Wilson naturally followed in Lu Yongchang's footsteps.

"By the way." Walking in front of the space elevator, Lu Yongchang suddenly said, "You reminded me."

"Since this is a battle of range, maybe we can bring out some old stuff."

Wilson cast a puzzled look at Lu Yongchang.

……

Mars City No. [-].

in an office.

The office door opened slowly, and a young voice came from the door.

"Old Qian, are you looking for me?"

The old man behind the desk took off his glasses, slowly raised his head and looked towards the office door.

After seeing who was coming, a kind smile appeared on his wrinkled face.

"Qiao Sheng, come in and talk."

The young man standing at the door walked into the office without any hesitation, and sat down respectfully on the chair in front of the desk.

"Teacher, what's the matter?"

Qian Zhengyang did not speak, but silently looked at the young man in front of him.

After a few minutes passed, Qiao Sheng asked tentatively again: "Teacher?"

Qian Zhengyang breathed a long sigh of relief, and said softly, "Qiao Sheng, from now on, you can go to Mars City No. [-] to work with Academician Cao Liangcai."

"Teacher?!" Qiao Sheng looked panic-stricken and exclaimed, "Did I do something wrong?"

The smile on Qian Zhengyang's face became softer, and he slowly shook his head: "No, you did nothing wrong."

"On the contrary, you are doing very well."

"Even if you stay in our deserted department, you can still calm down and do research."

"In the past few years, you should be the best student I have ever taken."

"Then, why..." Qiao Sheng's eyes were full of confusion and puzzlement.

Qian Zhengyang sighed again, waved his hand, and turned the holographic image in front of him to Qiao Sheng.

"Look at this, you should be clear."

In the holographic image, it is the result of the weapon test just now!

"This..." Looking at the amazingly powerful weapon in the picture, Qiao Sheng couldn't help but froze in place.

"Did you see it?" Qian Zhengyang shook his head helplessly, "Times have changed, and missiles are outdated."

Qiao Sheng didn't speak, but just stared blankly at the fragments of the Luanniao starship flying around in the picture.

"Then, what about you?" Qiao Sheng asked subconsciously.

"I?"

Qian Zhengyang shrugged with a smile: "I'm an old bone, what else can I do?"

"It just so happens that I can also enjoy retirement in advance."

"You are different, you are still young, and you can change directions."

"Don't worry, I will write you a letter of recommendation. Lao Cao and I have a very good relationship. When you get there..."

Although Qian Lao had a smile on his face, Qiao Sheng could see the bitterness hidden under the smile.

Qiao Sheng opened his dry lips slightly, but didn't know what to say.

"Academician Qian Zhengyang, there is a communication from the spaceport, is it connected?" Zero's voice sounded from the side, interrupting Qian Lao's chatter.

Qian Lao was stunned for a moment, and subconsciously asked, "Spaceport?"

"Yes, it's a communication request from Professor Lu." Ling explained softly.

The look of astonishment on Qian Lao's face became more and more intense: "Professor Lu?! Quick, get me through!"

……

On the holographic screen, Lu Yongchang greeted Qian Zhengyang with a smile on his face.

"Professor Lu, hello, hello." Qian Zhengyang said with a bit of respect in his eyes, "I don't know if you are looking for me..."

Lu Yongchang's gentle voice came from the side speaker.

"Mr. Qian, that's right."

"Considering that the new weapon has a short range and can only pose a threat to enemy ships within [-] kilometers, I plan to start the missile research and development project again."

"..."

Qian Zhengyang stared blankly at the holographic image in front of him.

For a moment, he actually felt a little dazed.

Project revived?

Missiles are not outdated?

Can he continue to study missiles? !

Questions flashed through his mind.

"Old Qian? Old Qian?" Lu Yongchang's voice came from the loudspeaker.

"Professor, I'm here." Qian Zhengyang responded quickly.

Seeing Qian Lao's expression, Lu Yongchang also guessed the general reason in his heart.

He chuckled and continued, "Old Qian, let me tell you again."

"In order to adapt to interstellar warfare, we need to increase the cruising mileage and cruising speed of the missile. The cruising mileage must be at least 30 kilometers, and the cruising speed needs to be above 1000 kilometers per second."

"Unlike those new weapons, missiles are mainly used for sneak attacks in interstellar wars due to the speed limit, so the concealment of missiles is more important."

"Are you confident in these?"
