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

"Zero, what does this signal mean?"

Lu Yongchang asked in a deep voice.

After mastering the Proxima Centauri dictionary, they can completely interpret the captured Proxima Centauri signals.

Soon, Zero gave his answer.

"Professor, there is no information contained in the signal."

"It's more of an active detection tool."

"Similar to our active detection radar, but with a slightly different frequency band."

Hearing this, Lu Yongchang's face sank: "How effective is our radar absorbing coating on it?"

Active detection methods have advantages and disadvantages.

The advantage is that it can detect surrounding enemy targets in real time and deal with upcoming strikes in advance.

The disadvantage is that once it is turned on, while releasing high-power electromagnetic waves, it also exposes itself to the opposite line of sight.

Therefore, the Earth Fleet has not started the active detection method for a long time, just to prevent it from being discovered by the Proxima Centauri civilization.

But the Proxima Centauri civilization on their parent star is different from the Earth civilization. They are destined not to hide their existence. Therefore, they can unscrupulously use high-power detection equipment to search for Earth civilization around the clock.

This is also the case, once the radar absorbing coating on the outer layer of the starship does not absorb it well...

That means that the human fleet at this time has been completely exposed to the sight of the Proxima Centauri civilization!

Everyone present is naturally aware of this.

Therefore, when Lu Yongchang asked this question, everyone stretched out their hands and fastened their seat belts, and made preparations for emergency maneuvers and blows!

"The absorption effect is good."

Zero's voice was as flat as ever: "According to estimates, we are most likely to be a slightly larger asteroid in the detection equipment on the opposite side."

"Just like the asteroid next to us."

Lu Yongchang subconsciously turned his head and glanced out the porthole.

An asteroid with a diameter of more than [-] meters dangled around the fleet.

"call……"

Zero's words let everyone breathe a sigh of relief.

Lu Yongchang wiped the cold sweat off his forehead with his hand, and said softly, "Everyone, since we haven't been discovered, it's time for us to work."

"Let's surprise the neighbors with something!"

As soon as the voice fell, Zhao Zijie on the side had already pressed the remote communication button.

"First Fleet, all members obey orders."

"Immediately lock on Proxima b!"

Like Zhao Zijie, the commanders of the other three fleets also quickly issued combat orders.

As the order was issued, Zero quickly sent the predicted trajectory of the ballistic trajectory and the trajectory of Proxima b to the onboard computer of each [Golden Crow] battleship.

A few seconds later, the response came.

"First Fleet, the locking mission has been completed!"

"Second Fleet..."

Seeing that the four fleets have completed the target locking, Lu Yongchang showed a ruthless look in his eyes, and shouted sharply:

"Fire!"

The moment the voice fell, countless tongues of flame spewed out from the gun barrels of the electromagnetic guns of the 250 [Golden Crow] battleships!

The energy generated by the fusion engine accelerates the projectile in the barrel to 6000km/s in a very short time!

After the projectile was ejected, it flew straight towards Proxima b, which is 0.95 astronomical units (AU) away!

These projectiles wrapped with miniature nuclear bombs will reach the sky over Proxima b in 6.57 hours!

"Zero, immediately change the direction of the fleet!"

After the blow was issued, Lu Yongchang immediately shouted: "Pay attention to the power of the Hall thruster!"

"Got it, Professor."

Under Zero's control, the fleet began to turn slowly, drifting in another direction like a ghost.

PS. In order not to get stuck in the plot, this chapter has been increased.

Chapter 266 A gift from thousands of miles away

Proxima b.

Central Academy of Sciences.

Augustus was wearing a unique black robe, pacing back and forth in the observation room.

"what's the result?"

Seeing an observer get up, Augustus quickly cast a questioning look at the observer: "Have you found any traces of solar system civilization?"

Facing Augustus' scorching gaze, the observer tremblingly shook his head.

When Augustus saw this, the aura around him was suppressed a bit again.

"Five years! Five years of searching!"

Augustus opened the breathing hole, exhaled a hot breath forcefully, stretched out his short and dry forelimbs, and slapped hard on the detection instrument in front of him.

"Not even a hair of the solar system fleet was found!"

The observer didn't dare to speak, but just stepped back silently, and sat back on the chair again.

"Your Excellency Augustus, is it possible that the solar system fleet has left?"

Aside, Nartes asked cautiously.

Augustus turned around abruptly, his six eyes staring at Nartes in front of him.

"Nartes! Do you think this is possible?!"

"They gave up the habitable star system in front of them and ran to find Ross 8.24, which is 154 light-years away?"

"That's nearly twice the distance!"

Nartes was momentarily at a loss for words.

That's right, unless the solar system civilization's brain is caught by the door, it is impossible to give up a piece of fat.

According to their hundreds of years of observations, within ten light-years, there are habitable solid-state planets in the solar system other than 4.22 light-years, and in the Ross 8.24 star system 154 light-years away.

Ross 154 (with Proxima b as the origin)

The atmosphere in the observation room was so heavy that it seemed as if water could be squeezed out.

"Continue to detect!"

Augustus' voice broke the heavy atmosphere in the observation room: "Give me the optical telescope!"

"Since electromagnetic waves cannot detect them, use your eyes to pick them out bit by bit!"

After the words fell, Augustus turned and walked towards the door of the observation room.

"Huh..." Seeing Augustus's back gradually disappearing at the door, Nartes slightly opened his breathing hole and breathed a sigh of relief.

He exchanged glances with several observers on the side.

Everyone saw bitterness and helplessness in each other's eyes.

Just when Naertes was about to say something, a rush of high-pitched sirens sounded in the Central Academy of Sciences!

At the same time, countless white warning lights lit up!

Nartes couldn't help but froze in place.

The high-pitched sirens were drowned out by the high-pitched shouts of the observers.

"Enemy attack! Enemy attack!!"

……

a few minutes ago.

In the synchronous orbit of Proxima Centauri b, there are a large number of defense facilities around the planet.

Laser cannons, electromagnetic guns, and various active detection equipment formed a dense defense network around Proxima b.

Suddenly, a large number of active detection devices sent an alarm to Proxima b!

There is no other reason.

The electromagnetic wave signal sent back showed that a large number of unknown objects moving at high speed suddenly appeared 120000 kilometers ahead!

……

"Damn it, what's going on!"

August's voice sounded again.

He moved his slightly withered lower limbs and returned to the observation room again.

"Your Excellency Augustus, the active detection equipment shows that a group of unidentified objects moving at high speed have appeared 12 kilometers away from us!"

Hearing this, August's heart sank.

coming!

"Is it the solar system fleet?" Augustus asked hastily.

Just find out where the enemy fleet is and the war will be much easier.

"Uh...it doesn't look like it. The data displayed by the detection equipment is a bit strange. Could it be an error?" Nartes looked at the monitor beside him and said doubtfully.

Not an enemy ship?

Suddenly, a fatal thought flashed through Augustus's mind.

He suddenly widened his three pairs of eyes, rushed forward and pushed away Nartes who was in the way.

When he saw the data displayed on the monitor, his six eyes showed a strong sense of horror!

"Quick! Prepare to intercept!"

"That's the projectile fired by the electromagnetic gun!!"

As he spoke, he glared fiercely at Nartes and the observers around him.

Damn it, no one can see such an obvious feature!

At a speed of 6000km/s, it only takes 12 seconds to cross the 20 kilometers.

Thinking that they had wasted nearly ten seconds of interception time just now, Augustus felt his teeth itch with hatred.

Time was limited, and he didn't have time to reprimand everyone, so he reached out and pressed the white emergency button on the side.

"quick!"

"Start the automatic interception program!"

"We must not let these projectiles attack our planetary defense equipment!"

……

The moment the white button was pressed, a radio command was sent from the Central Academy of Sciences to the planetary defense facility in synchronous orbit.

In the next second, under the control of the preset program of the central computer, the electromagnetic guns and laser cannons in the corresponding area started charging.

At this time, a full 12 seconds had passed since the discovery of the batch of projectiles.

The first batch of "gifts" sent by the human expedition fleet traveled across thousands of rivers and mountains, and arrived at a distance of 48000 kilometers from Proxima Centauri!

After one second, the interceptor weapon is fully charged.

The distance of the projectile to Proxima b: 42000 kilometers!

Under the control of the central computer, the laser cannon and the electromagnetic cannon instantly poured out huge firepower forward!

The short laser beam hits the target first.
