Speculation

"It's true that Level 4 Civilization doesn't have the Stellar Energy, but have you ever thought about it? Back then it was back then, and now it is now. Back then, when that Unknown Civilization crossed from the Perseus Arm to the Orion Arm, it was indeed a Level 4 Civilization, but who can guarantee that they didn't make any progress after reaching the Orion Arm?" Man Yuemei put down her crossed legs and said slowly. Her words clearly shared the same viewpoint as Yue Yuan.

After a pause, she continued, "Back then, we received information from the fake Interstellar Transaction Market of the Crimson Flame Civilization that it was the work of a Level 5 Civilization that crossed the spiral arm, heading towards the Perseus Arm. The Crimson Flame Civilization received the information from the real Interstellar Transaction Market, saying that it was a Level 5 Civilization that had betrayed the Perseus Commonwealth."

In my opinion, that Level 5 Civilization might not have become Level 5 Civilization when it rebelled, but rather after reaching the Orion Arm. Perhaps they dared to do so because they believed they could break free from the Perseus Commonwealth after discovering the Civilization Ruins. Now, regardless of the reason, we have found clues that an Unknown Civilization crossed from the Perseus Arm to the Orion Arm.

I think... if we follow this clue, we might find the culprit who destroyed our Solar System. On this trip to the Perseus Arm, if we encounter other local civilizations, we can also gather information on this matter.

Hearing this, everyone nodded in agreement.

Those who don't remember the specific details of the message they received from the Crimson Flame Civilization have already connected to the 'Tianhe Light' database through their Built-in Chip to search for it.

Upon this search, they discovered that the information humans had received back then was exactly the same as what Man Yuemei had said, except that Man Yuemei had missed one point.

The information obtained from the Crimson Flame Civilization back then also mentioned that the reason why that civilization defected from the Perseus Commonwealth seemed to be because they obtained some Characteristic Technology artifacts during an exploration of a Civilization Ruins, and also received news from the Previous Generation Voyager.

Looking back from the perspective of modern human understanding, the so-called Previous Generation Voyager were Precursor.

Therefore, it can be inferred that the Characteristic Technology creation is likely related to the Precursor's Characteristic Technology, or perhaps it is a Precursor- Characteristic Technology creation.

From this perspective, the civilization that destroyed the Solar System must still possess that kind of artifact. If humanity ever has the ability to seek revenge, they should be wary of that unknown, Characteristic Technology creation.

It seems that the discussion wasn't entirely fruitless.

Just then, a scientist in charge of Space Mine exploration suddenly pushed open the door and passed a report to Yue Yuan in front of him.

Yue Yuan knew what kind of report it was from the person who came, because he had ordered it. The report was to have a team of Expert Group an investigation team to use big data to extrapolate the time when the two satellites were destroyed, based on observations and explorations of the Space Mine, the on-site conditions, the geological conditions, the distribution of Rocky Satellite fragments, and so on.

The fact that this person has come means that the answer is already known.

After glancing at the report, Yue Yuan's expression became much more serious.

In short, this Space Mine existed at least seven thousand years ago, or rather, the two satellites were destroyed at least seven thousand years ago. Seven thousand years ago, that's a long time ago, which absolutely aligns with the human Earth Era. Like geological surveys, such time calculations have a huge margin of error, so seven thousand years ago is just a conservative estimate; the actual timeline could be over ten thousand years.

With the travel capabilities of Level 4 Civilization, reaching the Solar System from here is not actually that far, especially considering that the civilization that destroyed the Solar System had already reached Level 5 Civilization at that time.

Therefore, after seeing this report, Yue Yuan became even more convinced that the Unknown Civilization that had destroyed two satellites here was the prime suspect.

"Very good. Take a look at this report as well. You don't need to express your opinions. Just keep this in mind for now, and we'll find out more about it when we get to the Perseus Arm before making any plans." Yue Yuan shared the report with everyone present and uploaded a copy to the human data center for safekeeping.

The grudge of destroying our home planet can never be erased; we must find that damned Unknown Civilization and settle the score, provided that Human Civilization itself has the capability. According to intelligence, that Unknown Civilization has reached at least the level of Level 5 Civilization. Therefore, until humanity reaches Level 5 Civilization, we must remain hidden. Even if we find out the name of that civilization and their location, we cannot reveal that we are the survivors.

Otherwise, there may be utter destruction.

Of course, hiding doesn't mean we can't use the Human Civilization" to refer to ourselves. Even if we use the name "Earth civilization," other civilizations won't know where we came from. As long as we don't expose the detailed data in the database about the destruction of the Solar System, no other civilization will know that we are the survivors of that time.

This is how contact occurs between Cosmic Civilizations. After all, it involves translation. For example, the name "Nair Civilization" is a name given to them by humans from the Chinese character database after they learned the meaning of the translation.

However, just to be on the safe side, Yue Yuan felt it best not to say that he came from the Orion Arm Perseus Arm.

Only by concealing one's true intentions can one better survive. Only by surviving can one reason with others and seek revenge.

After a brainstorming session, and seeing that everyone present had finished reading the report, Yue Yuan changed the subject and said, "Alright, let's put this aside for now. The main reason I called you here is that I have an idea that I need you to consider."

Upon hearing Yue Yuan's words, Yi Kai made a move to get up and leave, because he felt that there was really nothing for him to do here, and it would be more enjoyable to go back and be with his wife and discuss the mysteries of life.

Humanity has been Level 4 Civilization for a long time, but there hasn't been much progress in Life Science. Take human enhancement technology, for example; it's still based on the technology used in Level 3 Civilization. As a leading figure in Life Science, Yi Kai is under a lot of pressure. Recently, because of this, there have been many voices saying that if he can't produce results, he shouldn't occupy the position.

He was also a little annoyed by these rustling sounds, so he made an excuse to come to Yue Yuan's place to relax and see an old friend from the Earth Era.

After reminiscing with Yue Yuan about things from the Earth Era and listening to these people talk about the Perseus Arm, Yi Kai felt much better.

However, just as he stood up, Yue Yuan stopped him, saying, "Academician Yi might as well listen too."

Life Science can't be rushed. Yue Yuan had looked into it and found that neither the branches of technology developed from the core theory of Level 4 Civilization nor the main technological path were closely related to life and genetic engineering. It was no surprise that Yi Kai couldn't achieve any results.
