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

After a short wait, the wake-up procedure began, and Zero's unique electronic synthesis sound sounded from the speaker.

"Professor, professor!"

……

In the technology tree space.

Lv Yongchang hung in the air and "sat" in front of the bright white technology tree, staring blankly at the mottled background in the distance.

In front of him was a cursor with a brightness of over 50%.

【Tachon Radar】

After mastering the curvature technology, a new problem emerged.

After entering the curvature navigation, the ability of the starship to observe the outside world has been greatly reduced.

the reason is simple.

The existing observation methods are all developed based on the speed of light universe.

Therefore, when the speed of movement exceeds the speed of light, the previous means of external observation will fail on a large scale.

For example, when a person is flying faster than the speed of light, the naked eye can only see the starlight in front of him speeding up and "rushing", while the starlight behind him can no longer catch up with you.

The same goes for starships.

Calculation and processing of the information transmitted from the front of the starship can well restore the scene of the starship's forward direction.

Information processing for the rear or the side... humans don't have a good solution at the moment.

Therefore, today's planetary-level warships have a huge flaw after entering super-light speed navigation-once they encounter an attack from the rear or side, the warship will be like a blind man, unable to evade and counterattack at all.

In other words, in order to cope with possible future wars, the current human fleet urgently needs a radar that can be used in a state of curvature navigation.

Since this will not affect the normal navigation of the starship, the Academy of Sciences lowered the priority of this research slightly at first.

The Academy of Sciences did not put this research on the agenda again until the rest of the basic research was completed.

The tachyon radar in the technology tree system can just meet this demand.

Under the action of gravitational field and external energy, tachyons will change slightly.

Tachyon radar is manufactured based on this characteristic.

However, limited by the nature of tachyons, it has a huge difference from previous active detection radars—it is a passive detection radar.

But this will not affect the detection accuracy and detection efficiency of tachyon radar.

Whether it is the planetary-level gravitational field, or the gravitational shield of the planetary-level battleship, the curvature bubble...these will trigger the reaction of the tachyon radar.

Coupled with the superluminal characteristics of tachyons, tachyon radar can even achieve passive detection of surrounding areas without delay within the allowable range of accuracy!

There are advantages and disadvantages.

In the case of having the great advantage of superluminal detection, it also has a huge disadvantage-in the case of insufficient precision, when the detected object is too backward or too small, it will not be too large. big response.

For example, a small meteorite.

Its gravitational field is too small to induce frequency changes of tachyons.

Another example is starships of level [-] civilization and below that have not yet mastered gravitational technology.

The mass is relatively small, and they have not mastered sufficiently powerful gravitational shield technology and curvature bubble technology, and cannot induce the response of tachyon radar. Even if the detection accuracy is greatly improved, it is easy to regard these starships as a star in the universe. asteroid.

This is exactly why the Sweeper civilization was forced to use a carpet search for the human civilization fleet.

But is this a problem?

no problem.

For today's human civilization, or for higher-level civilizations, how much difference is there between a starship of level four or below and an asteroid?

"professor……"

"professor!"

The faint calling sound interrupted Lu Yongchang's thoughts.

After a little identification, he realized that it was Zero's voice.

He stopped his thinking, glanced at the bright white technology tree and the mottled background again, and with a movement of consciousness, he directly exited the technology tree space.

……

"Professor, professor..."

With the return of consciousness, the calling sound in the ear quickly became clear.

Listening to the unchanging, stiff electronically synthesized sound without much ups and downs, Lu Yongchang felt his teeth ache.

He opened his eyes suddenly: "Okay, stop howling!"

"teach……"

The electronic synthesis sound stopped abruptly.

"What happened?" Lu Yongchang subconsciously frowned and asked as he looked at the orange warning message flashing in front of him.

"The expedition fleet sent a tachyon message. The fleet has arrived in the coordinate area, and the target fleet has not been found yet..."

Lu Yongchang reached out and clicked on the message, quickly glanced at the content, and said in a deep voice: "It's only been less than 4 months, and they can't run far."

"Tell the expedition fleet, let them send detectors to conduct a carpet search!"

"Also, if there is a war, let Zhao Zijie do a good job in command."

"receive."

Chapter 689 Eugene Civilization

The holographic projection has once again returned to its previous azure blue color.

Lu Yongchang exhaled a long breath, raised his hand to operate on the holographic image.

He opened the [Tachyon Radar] plan at the beginning, marked the places with obvious loopholes, and corrected and improved them one by one.

Then, he recorded the inspirations generated in the technology tree space one by one.

The research progress of tachyon radar is advancing steadily and slowly.

The brightness of the cursor in the technology tree space also slowly increased with Lu Yongchang's movements.

……

9.16 light-years away.

The United Expeditionary Fleet.

When the tachyon information appeared on the holographic projection, Bai Yixuan, who was sitting in the command center of the Titan Mothership, slowly got up from his seat and gave the order with a serious expression.

"Attention all units, start a carpet search!"

After the voice fell, the hatch on the side of the battleship quickly opened, and silver-white spherical detectors swarmed out, and flew in all directions under the impetus of the anti-matter engine.

After leaving the fleet for a certain distance, these spherical probes activated the curvature engines one after another, and disappeared into the visible universe.

……

In the silent and dark universe, an unreasonable scene appeared.

A not-so-large fleet maintained a steady speed, catching up with the fleet ahead.

Comparing the two fleets, the pursued fleet is not only larger in size than the chasing fleet, but its flight speed is also much higher.

Even from the outside, the pursuit fleet looks like a motley army, and the surface of each starship of different styles is full of traces of war.

In that small and chaotic fleet, there is a relatively large starship.

That's their flagship.

Inside the flagship, a series of intelligent creatures with a ferocious appearance are concentrating on completing their own tasks.

The orange-yellow vertical pupils, the fine scales all over the body, the elongated and forked tongue, and the sharp fangs in the feeding organs all show the characteristics of their carnivorous race.

They once lived on a barren desert planet, and their ancestors were a group of carnivorous lizards.

They were originally cold-blooded and temperature-changing animals, but with the "help" of lack of resources, they were further shaped into an extremely cruel and brutal race.

After evolving wisdom, this group of lizardmen built a highly hierarchical society and successfully lit up space technology.

They named their home planet Eugene, and at the same time called themselves Eugene civilization.

This civilization, which is still under the feudal monarchy, is a real star thief civilization.

Under the strict and strict hierarchy, the Eugene civilization is full of cold and cruel atmosphere.

After leaving Eugene, they have been active in this star field with a brutal and fearless combat style.

Looting the materials of low-level civilizations and stealing the technology of high-level civilizations...

In battle after battle, this star thief civilization composed of lizardmen successfully promoted to a third-level civilization.

hundreds of years ago.

The probe sent by Eugene's fleet is eyeing a star system with fertile resources.

But these resources did not arouse the interest of Eugene people, after all, they are not good at mining and developing technology.

Instead, it was a third-level civilization living in it that caught their attention.

The long-term peaceful life of the Talodan civilization made it neglect the development and research of weapons and equipment.

But in other aspects, the technological level of the Talodan civilization has reached the pinnacle of the third-level civilization.

They even started research work on antimatter engines.

From the perspective of Eugene Civilization, Talodan Civilization is like a huge experience baby.

This is simply a gift from the universe to Eugene's civilization!

Thank you for the gift of the universe! !

On the day the Talodan civilization was discovered, the emperor of the Eugene civilization uttered this exclamation more than once.

"Has the mothership responded?"

Kolei, who was sitting in the central area of ​​the command room, opened his mouth full of fangs and asked.

"General, the siege plan has begun!" In the distance, a sailor hurriedly responded, "The mothership has dispatched ten squadrons, ready to encircle the Talodan fleet from all directions!"

General Corey twitched the corner of his mouth, revealing a cruel grin: "Very good."

"I want to see how this unarmed civilization can escape our siege."

Thinking of the advanced propulsion technology of the Talodan civilization, Kolei's erect pupils shrank slightly, revealing a strong color of greed unabashedly.

With the advancement technology of Talodan civilization, the strength of Eugene civilization will be improved like never before!

And it will also be commended by the emperor!

While fantasizing about various scenarios, Corey let out a breath mixed with the smell of blood, then got up and left his seat.

Coming to the gate of the command room, looking at the constantly rotating corridor in the distance, it loosened its muscles and got into the bridge connecting the corridor and the command room.

A faint sense of weightlessness followed, which intensified as it advanced.

It unhurriedly controlled its own direction with its claws, and floated towards the corridor.

The command room can rotate by itself and generate a certain amount of equivalent gravity, which is considered a luxury for a starship of a third-level civilization, but it is also the reason why it chooses it as its flagship.

With its identity and status in Eugene's civilization, it is worthy of such treatment!

The guards waiting in the corridor saw it and quickly saluted it to show their respect.

"Come on, follow me to the processing factory."

"Those wastes should also be processed into cans. Just in time, I will add a meal to everyone before the war begins."

Corey said in a natural tone.

Similarly, those guards nodded as a matter of course, and even showed a ferocious smile of excitement on their faces.

In the Eugene civilization, this is already a well-established tradition.

For the egg-laying Eugenes, the population size has never been a big problem.

Chapter 690 Talodan will never be a slave!
