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

"Why do we go near a black hole?"

"There...is not a safe place."

He Bilin's words resonated with many people.

As the most powerful celestial body in the universe, even a small black hole is not something humans can contend with today!

Its huge gravitational force makes the escape velocity in the event horizon exceed the speed of light.

Simply put, within a certain range, even light cannot escape the attraction of black holes.

Such a dangerous area naturally aroused the concerns of many researchers.

What if... the human fleet has an accident and enters the horizon of the black hole, what should we do?

Lu Yongchang sighed slightly: "Do you still remember what I said not long ago?"

"We lack a constant that describes the gravitational field."

Seeing everyone around nodding, he continued to explain.

"Only by finding the illusory graviton can we have a chance to obtain that constant."

"If you want to get gravitons, the energy of the circumsatellite particle accelerator is far from enough."

"Of course, we can build larger particle accelerators." Lu Yongchang shrugged, "For example, around the dawn star, or around Gliese 555, or even a particle accelerator around the galaxy."

"But we don't have the time."

Lv Yongchang's eyes dimmed a bit: "We don't know when the Pastoral School will come here."

"So, I thought of a shortcut."

Lu Yongchang turned his head to look at the marked small black hole in the holographic projection, and his eyes showed a bit of longing: "Perhaps, we can find that mysterious graviton by virtue of the strong gravity of the black hole."

He Bilin and a group of scientific researchers suddenly realized, and their eyes showed a look similar to that of Lu Yongchang.

That's a black hole!

The most powerful celestial body known to man so far.

No scientist can resist the allure of black holes.

If so, replace it with a larger black hole.

……

"Beep! Beep! Beep!"

Harsh sirens came from all around, interrupting the imagination of Lu Yongchang and the scientific researchers.

Seeing the bloody holographic warning signs constantly appearing around him, Lu Yongchang suddenly came back to his senses.

"Zero, what happened?!"

Before the words fell, the familiar electronic synthesizer sounded.

"Professor, the antimatter collection device located outside the Gliese 555 star system has detected UFOs!"

The antimatter collection device was put into use before the Dyson Sphere Phase I project.

The antimatter collection device similar to a huge funnel "wanders" around the Gliese 555 star system, collecting the antimatter scattered in the universe.

At the same time, these antimatter collection devices also integrate high-precision detection units.

It can also be regarded as the first warning line of human civilization.

Therefore, when Lu Yongchang heard the words, his expression changed drastically.

UFOs outside the star system...

Subconsciously, he thought of the pastoral civilization he just mentioned.

"So fast?!" He blurted out, "How is it possible?!"

The researchers around him naturally had the same idea.

There was more or less panic on everyone's face.

In the originally peaceful laboratory, the atmosphere of panic is spreading.

"calm!"

Lu Yongchang looked serious, and shouted in a deep voice: "Why panic, I haven't confirmed the specific situation yet, calm down!"

"According to the information disclosed by [Hua], there is only [Hua] a pastoral civilization in the Milky Way."

"That is to say, other idyllic civilizations need to sail across the river system to come to us."

"How much time has passed?!"

Under Lu Yongchang's shouting, all the scientific researchers managed to regain their composure.

Looking at the eyes of everyone around him, Lu Yongchang gave orders one after another in an orderly manner.

"Zero, inform Zhao Zijie that, except for [Earth], the starships belonging to the battle formation will set sail immediately."

"Activate [Guangwei Planetary Fortress]."

"Preparing to start the [Dandelion] project."

"..."

While giving the order, Lu Yongchang's eyes revealed a bit of worry.

Yes, normal interstellar travel cannot have such a high speed.

But what if the opponent has mastered wormhole technology?

According to the superstring gravitational field equation, it is possible to realize the wormhole technology.

"Yongchang, the real-time image is out."

Fang Xu's voice came from the side, and at the same time, a holographic projection with azure blue background was dragged to his side.

Lu Yongchang quickly concealed the worry in his eyes, and turned his attention to the holographic screen.

With just one glance, he froze in place.

UFOs appear spherical and dark gray throughout.

About [-] meters in diameter.

Very small.

Its flight speed is not fast, even slower than the antimatter collection device on the side.

"This is not pastoral civilization!"

Lu Yongchang looked at the picture with some doubts, and murmured in a low voice: "If the [painting] is telling the truth, the pastoral civilization should be all dimensional creatures."

"Just like [painting], it's either a low-dimensional life, or a high-dimensional life that we can't see."

"Anyway, it can never be like this!"

Chapter 532 Sixth Level?Seventh grade?still……

The burden in Lu Yongchang's heart was suddenly relieved.

It’s better if it’s not pastoral civilization.

But the next moment, a new confusion emerged in Lu Yongchang's heart.

It's not an idyllic civilization, so what is the origin of that spherical flying object that looks like a high-tech content outside the Gliese 555 star system? ? ?

Lu Yongchang, who was staring at the holographic projection, suddenly realized a problem.

"only one?"

Lu Yongchang glanced at Fang Xu in surprise: "Are there no other similar flying objects?"

Fang Xu shook his head, and responded with some confusion: "So far, the antimatter collection device has only detected one UFO."

Lu Yongchang's face changed slightly.

This act of single-handedly coming to a strange star system...

"Detector?!" Lu Yongchang and Fang Xu said in unison.

Seeing the other party express their inner guesses, both of them showed knowing smiles on their faces.

"It's just a detector." Lu Yongchang breathed a sigh of relief, and said with a relaxed face, "I was shocked, I thought the pastoral school would come here so soon!"

Fang Xu's face was also full of rejoicing: "Yeah, I don't know what level of civilization would be interested in such a barren star system."

"I guess it shouldn't be some advanced civilization."

Lu Yongchang chuckled, nodded in agreement, and then said casually: "Zero, how did it appear? Where did it come from?"

"Tune up the video and show it to me."

The voice fell.

The holographic projection screen changes rapidly.

A familiar picture then appeared in front of him.

Darkness, deathly silence, only the dots of light in the far distance can bring some peace of mind.

Suddenly, there was a slight change in the quiet and dead scene.

Without any warning, a dark gray spherical flying object suddenly appeared in the screen.

Seeing this scene, Lu Yongchang only felt his heart skip a beat.

broken.

This unusually "familiar" picture directly touched the DNA of everyone present.

"Damn it!" *N

"Curvature Sailing!!"

For a while, the laboratory fell into "panic" again shortly after returning to tranquility.

The original relaxed expression on Lu Yongchang's face has all disappeared, replaced by an unprecedented solemnity.

"how is this possible……"

"With curvature navigation technology, at least it is a level [-] civilization that has developed to a certain extent."

"How could they be interested in this barren land?!"

Before he had time to think too much, Lu Yongchang said directly: "Zero, send out detectors and adjust the orientation of every nearby antimatter collection device. I need to see the whole picture of this detector!"

"Roger that!"

The moment the electronic synthesizer sounded, the angle of the picture in the holographic projection also began to change.

The camera moves slowly.

The whole picture of the detector then appeared in front of the eyes of all the researchers.

suddenly.

"Where's its power system?!"

Fang Xu's horrified voice came from the side: "What is he driven by?!"

Lu Yongchang didn't reply, but looked gloomyly at the holographic projection in front of him.

No Hall propulsion.

No antimatter engine nozzles.

And no messy propulsion system nozzles.

The entire detector is a perfectly round sphere!

But it is such a sphere that is flying towards the Gliese 555 star system unswervingly!

What a big deal!

There are only these four words left in Lu Yongchang's mind.

Although the pastoral school didn't come, an equally terrifying advanced civilization came!

Although he still doesn't know what civilization sent the detector, but from the curvature navigation and the mysterious propulsion system, it can be seen that the civilization that made this detector is definitely not something that today's humans can resist!
