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

They have never experienced such a high-pressure environment, and they have no plan to deal with it!

"[Zanka] Ah..."

Sure enough, a crew member wailed: "Save your poor people!!"

The wailing of this crew member, like the fuse of explosives, instantly ignited the negative emotions in the hearts of all the crew members.

"Leader, let's, let's turn around and fight them!"

Another crew member looked red-eyed and shouted like crazy: "We have no way out, how about..."

"Nonsense!" Aldan yelled violently, "Everyone, please be quiet!"

"Haven't come to the real desperate situation, cheer up!"

"Please believe me, last time I was able to lead everyone out, this time, I can also lead our civilization to live!"

The leader Aldan's shout temporarily stabilized the morale of the army.

The voices of crying father and mother in the command center quickly decreased.

"Milo, go and choose the fleet's next target star system." Aldan gave the order in a deep voice without any hesitation.

"Mullon, estimate the fuel situation of the fleet after acceleration, and assist Milo in screening star systems according to the range of navigation."

"Yes!"

Milo and Mullen responded in unison.

……

452 light-years away from the star system Kepler 4.2.

A spherical probe flicks across the empty universe at a speed of 0.5c.

The antimatter engine behind it was working at full capacity, spewing out extremely strong gamma rays.

It is a part of the vigilance network of human civilization around the star system.

At present, with the efforts of human civilization, this warning network has spread to the area of ​​5 light years outside the star system.

With such a wide range, it is destined that the alert density will not be too high.

A detector is often responsible for the detection and security of a large area.

As usual, this spherical detector is carrying out the exploration mission according to the planned route.

This should have been a dull and boring thing, at least, for the past six months, it has been.

"Drip drip..."

A message came from the sensor. It seems that something has been discovered in this empty universe.

The computer in the detector quickly analyzes and verifies this information.

In a very short period of time, the computer has completed the processing and rating of this information.

AAAAA!

Without any hesitation, the computer quickly sent the information back to the Kepler 4.2 star system 452 light-years away.

In the vacuum, tachyons quickly dissipate the newly acquired energy, and leave two gamma rays with different frequencies traveling in opposite directions in the illusory universe.

……

Kepler 452 star system.

After several years of steady development, the Kepler 452 star system at this time has become an extremely busy "metropolis".

From the main star to the boundary of the star system, medium and large starships can be seen everywhere.

Machinery has become the main theme of this star system.

The tachyons coming from afar passed through this area at a very high speed, leaving behind two distinctive gamma rays, and then flew towards infinity at a higher speed.

The tachyon information receiving point set up near Kepler 452c quickly captured these two special gamma rays.

Information processing and translation work take hardly any time.

This information from 4.2 light-years away appeared in Zero's "sight" in just a few milliseconds.

Its priority continued to rise and quickly overwhelmed all missions currently being carried out within the fleet.

In the next instant, an extremely piercing siren sounded in 【Earth】!

Chapter 684 Yevgeny's Plan

Inside the office.

At the same time as the ear-piercing siren sounded, the holographic projection in front of Lu Yongchang also turned blood red.

At the same time, a message with the highest priority directly covered all the messages and popped up in front of his eyes.

"Professor, a UFO was found 4.2 light-years away."

"Preliminary judgment shows that the probability that the aircraft is a probe of an alien civilization has reached 99%."

At the same time, an image from 4.2 light-years away appeared in front of his eyes.

"4.2 light years?"

This familiar distance caused a ripple in Lu Yongchang's heart.

At that time, the distance between the earth and the neighboring galaxy was exactly 4.2 light-years.

The natural moat at that time, in today's view, has become a small gully at the door of the house.

This can't help but make Lu Yongchang feel countless emotions.

Looking at the slightly worn-out ellipsoidal detector in the holographic projection, he slightly raised his eyebrows and put down his work directly.

"This is……"

Looking at the extremely familiar engine style behind the ellipsoid detector, the joy in Lu Yongchang's eyes instantly became intense.

"Hall Thruster?"

"What about its flying speed?" Lu Yongchang asked Ling in a slightly hasty tone.

"The current sailing speed is 0.35c."

Lu Yongchang stood up abruptly from his seat and rubbed his hands excitedly: "The sailing speed is quite standard!"

"It should be a detector sent by a second-level or third-level civilization."

"Yongchang!!" Fang Xu's shout came from outside the office.

Swish.

The office door suddenly opened.

Fang Xu rushed into the office eagerly, and shouted loudly: "Yongchang, did you see it?!"

"It's time, it's finally time!"

"The Sociology Branch has sent me a message just now, asking me when..."

"Wait." Lu Yongchang interrupted Fang Xu's words, "Don't be too happy first."

"Have you forgotten the lesson of that time?"

"You mean... this detector may be a smoke bomb thrown by a higher civilization?" Fang Xu's excited expression gradually subsided, and he asked in a low voice.

"Or it's a bait." Lu Yongchang said softly, "That's what the star robber civilization, the Rathor civilization, did."

"Then you mean..."

Lu Yongchang turned his hands away and paced back and forth in the office, his eyes revealing a bit of contemplation.

"Prepare for battle!"

Lu Yongchang's eyes flashed, and he made a decision: "Using such an outdated detector as a bait, the civilization behind it is nowhere stronger than it should be."

"Even if there is a fifth-level civilization behind it, humans today can touch it!"

While speaking, Lu Yongchang boarded the robotic arm robot with the help of the mechanical arm, and then he waved to Fang Xu: "Go! Come with me to the command center!"

……

【Earth】command center.

In the huge holographic projection, the old ellipsoidal detector still maintained its own course, sailing forward silently.

From time to time, a device similar to a wiper will gently sweep near a few lenses to take away some interstellar dust attached to it.

Behind it on the right, a spherical detector quietly followed it like a ghost, waiting for the capture command from the command center.

This quiet and peaceful scene formed an extremely sharp contrast with the tense and anxious atmosphere in the [Earth] command center.

"It's strange, hasn't it found our detector yet?"

He Bilin frowned, and murmured in a low voice: "Why can it maintain its own route so calmly?"

"Could it be... is it really a bait thrown by a higher civilization?"

He Bilin's words caused a slight commotion.

Lu Yongchang raised his eyebrows, and explained softly: "At present, our detector is in a silent state, and we have also used tachyon communication to communicate with us."

"If the opponent is really a second-level or third-level civilization..."

"At this distance, it really can't find our detector."

The corner of He Bilin's mouth twitched slightly: "Then... what if it's bait?"

"Then we will be in big trouble." Fang Xu took over the conversation, "Prove that the advanced civilization behind it doesn't panic us at all."

"I'm afraid that only advanced civilizations of level six or above have such confidence."

"It's unreasonable." Academician Lin Zile from the Sociology Branch interjected, "A level [-] civilization should not use such petty means of stealing."

"Just like we can't use an ant as bait."

"The gap between the two is too great!"

Lu Yongchang nodded, expressing his agreement with Academician Lin Zile's words: "Therefore, I prefer that the other party is really a low-level civilization."

"The key question now is how we should use this detector to lock the position of the opponent's civilization."

……

This question raised by Lu Yongchang has aroused heated debate.

Some academicians believe that we should establish a connection with the other party, and then slowly map it after gaining the trust of the other party.

Most of the academicians of the Sociology Branch share this idea.

After all, if this plan is successful, human beings might soon be able to have a truly subordinate civilization.

[Nus civilization]?

The human fleet has not yet found a suitable planet to serve as their habitat. As of now, the entire [Nus Civilization] still has only one small tree that is not too big living in the laboratory, so it is not a subsidiary civilization in the true sense. .

Of course, this plan was opposed by many.

Too time consuming, too many variables...

In short, under the opposition of most academicians, this proposal was the first to be rejected.

The plan to live to the end was proposed by Academician Yevgeny.

Lu Yongchang looked at the extremely simple and crude plan in front of him, and the corner of his mouth twitched suddenly.

He scrutinized the other proposals, and finally sighed deeply.

"Just this plan."

"Zero, start executing."

……

Following Lu Yongchang's order, in the peaceful universe 4.2 light-years away, an undercurrent began to slowly surge.

The two spherical probes in the adjacent area quickly entered the state of curvature navigation, flying towards the destination.

Considering the short distance between the two sides, the speed of curvature navigation is kept at 1.01c.

When the other two spherical detectors are about to reach the target, the spherical detector that has been following the ellipsoidal detector also enters the state of curvature navigation!
