"Nothing, I lost..."

Behind the isolation gate, there is a very open place. Through the feedback information of ultrasonic and electromagnetic waves, the two collectors know the general environment of the interior in a short time.

Behind the gate is a closed environment, so it is ensured that the gas does not leak out. This closed environment is not specially built, but is composed of two gates closing the main road.

This confined environment is very empty, except for some metal fragments, the collectors did not find anything through scanning.

"Wait, there is a text message here."

With the help of infrared spectroscopy, one of the two collectors found a text inscribed on a metal wall.

[...In the end, we still suffer from our own evil results, and our inevitable destiny is inevitable. All our efforts are ultimately in vain...I have never believed in destiny, but now I have to believe in it. At this moment, it is troubled in my mind. There is still no answer to the question for a long time, and there will be no chance to know again in the future-if we had not been in contact with the spiritual realm in the first place, would the result be better than it is now? Or...]

"Not finished?"

"It's uncomfortable. Just write it all. The previous text messages are like this..."

The burned text was not complete, it seemed that the writer was interrupted before the burn was completed, which made the two collectors who browsed the information feel uncomfortable.

The writer's information was not burned completely. Naturally, there was a reason, and the collector was investigating its surroundings.

"There are no signs of fighting, and no corpses."

"What is this indicating?"

"Explain that the writer voluntarily left based on his own will for some reason."

The collector guessed that the probability is higher, and the other possibility is that someone attacked the writer who was recording the information and erased the trace.

However, the latter may be somewhat redundant. The crisis faced by Perdue civilization is to the extent that civilization is destroyed. The attacker attacks the writer, and there is no need to erase the traces, unless the attacker can predict the future and know the collector early. We will visit here.

This is obviously impossible, so they tend to the former, what is the reason for the author, based on their own will not to burn.

"There are also two gates. The gates show no signs of damage, and there are no other hidden passages. The writer left before the two gates were lowered."

Some nonsense, but this is the condition of analysis, so it must be listed.

"Is it because I saw the gate lowered and I left in a hurry in order not to be sealed?" one of the individuals asked rhetorically.

The gate is very thick. If the writer of Perdue Civilization does not carry the tools for breaking the gate, when the gate is lowered, he will undoubtedly be trapped in it.

But after careful consideration, the collectors felt that some places were unreasonable.

"Then why did the writer deliberately choose this place to leave a message? Wouldn't it be possible to finish writing with peace of mind if you change the place?"

It can be seen from the text message that the writer is very desperate and very powerless. If there is room for reversal, it will not be enough to leave such a message. It can be deliberately placed on the wall in two situations. One is that time is tight. I just found a place to burn it. The other is that I already know that the destruction of civilization is inevitable and unchangeable, so I write down my last words by burning it on the wall. Temple Street

But the problem is that no matter what the possibility is, it doesn't seem to be a problem to pick a place that is not disturbed to write. Even if it is the former possibility, the writer can run outside the gate to continue writing.

"Other places are tattered. If you burn them in other places, it is very likely that you will not be able to save what we see now... Huh? The author clearly knows that this place can survive the crisis of ruining civilization?"

The collectors think about it, but they can only think that the author himself clearly knows that the enclosed space formed by the gate can allow the text information inside to survive the crisis of the demise of civilization, so he will deliberately leave it in the enclosed area of ​​the gate. Text.

But based on this guess, the collector thought of another question.

"It's a bit weird. Since it is possible to survive the crisis of destroying civilization, why not transform it into a refuge? Or imitate the structure here and create a refuge for the continuation of civilization fire."

"It really feels a bit strange. In terms of industrial capabilities, it should be no problem to create a ring of stars and create a similar refuge in a short time."

In terms of industrial capabilities, Perdue civilization is the second most technologically advanced civilization among the alien civilizations known to collectors. Although a considerable part of it uses technology developed in the spiritual realm, it can create rings of stars. The stellar ring, its own industrial capacity has surpassed the current collectors have seen, except for all alien civilizations except Hui civilization.

Thinking in another way, the collectors can create this kind of refuge in an emergency, and there are more than one. There is no reason that Perdue civilization can't create it.

"Or the writer can stay here. Although there is nothing here, it is definitely more protective than other places, and will be able to live longer when a crisis comes."

"But the writer didn't do this, why?"

"……do not know."

The desire to survive, this instinct derived from the most root of living things, is not easy to overcome. For the life that is about to die, even if one more second lives, it is still alive.

The doubts in my mind cannot be answered because there is too little information.

However, fortunately, it is not without gain. Collectors can at least be 100% sure that the destruction of Perdue civilization is directly related to the spiritual realm.

...

The exploration of the ring remains near the end, and the collectors will bring the explored information back to the cluster network for analysis ~lightnovelpub.net~ to build a physical model of the ring remains.

From the physical model, the collectors found something surprising to them-the star ring of Perdue civilization, when Perdue civilization died, it was very likely that it was still in a state of intact.

All the damage to the ring remains is due to its own reasons, rather than structural damage caused by external factors.

"The damage simulation here and here shows that it is the damage caused by the explosion of the nuclear reactor."

"There are also these places. From the analysis of the wreckage, this place was originally an ammunition depot. The loss of control of the reactor led to the martyrdom..."

"Due to the loss of control of the reactor, the ring-stellar accelerator can no longer maintain the electric field, and the subluminal particles inside broke through the ring wall, so a big hole appeared in the ring remains."

What happens if the stellar ring loses its energy supply? Without energy to maintain the internal electric field and lose the internal sub-light-speed particles, strong gravitation can no longer be formed. The strong structure formed by the use of gravity and the inertia of the sub-light particles will collapse.

"...All the reasons for the destruction of the ring ruins are actually caused by no one to maintain?"_
