There are many mysteries to solve, and to really sort out his thoughts, Long Yun's first consideration is the true intention of his mission.

As a newly recruited KGB agent, going alone to the "dead city" to investigate the truth about the night of the tragedy, there will be two levels of interpretation of intentions: first, through the collection and analysis of clues, to find out what the truth of the tragedy is, and second, if the truth is found, how to report it to the KGB and even General Secretary Malenkov?

These two questions seem to be the same thing, but in fact they have different meanings.

To put it bluntly, since he went to investigate with some purpose of his own, Long Yun needed to carefully consider everything he saw in the "Dead City", rather than reporting the situation without reservation.

On this issue, while walking through the underground base and thinking at the same time, the judgment gradually formed in his mind became clearer and clearer, and he checked the situation at that time in the central hall of the underground space, and looked through a lot of fragmented materials, Long Yun is now more sure of this, no matter what happened to the tragedy seventeen years ago, it seems that it is not because of the research of the "Rome" base.

Or, to put it more precisely, the entire "Rome" base seemed to have suffered a tragedy unsuspectingly, far from what he had imagined.

Before entering the "Dead City" for the second time, he knew nothing about the world after the "Black Wall", and although Long Yun had stayed in this abandoned base, he did not have the time or opportunity to investigate the secret research conducted in the base in detail. In his vision, since he found a huge reserve of "energy media" here, he also established a large-scale secret base. There must have been some plans on the part of the KGB. And then something went wrong in the course of a series of top-secret studies. will lead to the sudden explosion of mysterious power, and no one in the base will be spared......

Such speculation seems to be more reasonable.

However, now, what Long Yun saw in front of him was not like this, he used the "black light" with no sense of tone to explore every corner of the underground space, although he didn't have time to look through all the places, and many of the equipment in the hall couldn't be named at all, but with the paper materials that he searched out one after another, he read and strung together the events in his mind. He also had a general impression of the day-to-day operations of the "Rome" base.

These materials may have been yellowed on the paper, but they could not be seen under the "black light", in fact, thanks to the fact that computers and other information products were still relatively primitive in that era, and in many workflows, the intervention of computers was very limited, and scientific researchers and ordinary workers were more accustomed to making paper records.

With this favorable condition, Long Yun paid attention to collecting these materials during the exploration process, read them in a hurry at the relatively short time, recorded the synopsis, and if it was something long, he temporarily marked it and put it back in its original place - this is the only way for the time being, he came to the "dead city" this time. Although it is to investigate and collect evidence and collect clues, it is necessary to say that all the materials in the huge area behind the "black wall" are loaded onto trucks and taken away. That's also impossible.

It was in this kind of hurried reading and sorting out his thoughts that Long Yun gradually figured out that from the discovery of energy media by the expedition team in the hinterland of Central Asia to the outbreak of the tragedy of the "Rome" base, this period is not a long time, in fact, this secret base has been under construction, large-scale construction and practical preparations, but there are not many real projects that have been carried out. Moreover, the progress made in these early developments is indeed very impressive judging from the few documents that have been left behind, but these conclusive things, as well as the related numbers, are probably all preserved together with the old computers and tapes in the underground base of Zài, and now of course they have become a pile of waste.

In this way, Long Yun soon discovered that the tragedy that befell the "Rome" base was obviously not caused by some dangerous superpower, but rather a "natural disaster" without warning.

The value of this judgment is undeniable that it is a "natural disaster", not a "man-made disaster".

In the huge empty underground space, he still habitually walked forward with a gun, and he never found any evidence of "man-made disasters", or the chaotic scene of the failure of the real yàn, and the same was true on the paper materials in the base, and there was no mention of any superpowers with unknown prospects and extremely high risks, let alone any clues that "real yàn may cause serious consequences".

From passing through the "black wall" to now, he has been entrenched in the entire building for a long time, as far as Long Yun's overall impression of this underground base is concerned, although more than ten years have passed and the scene in front of him has long been different, he can still feel the operation scene in the base back then.

Before the "tragedy" broke out, it seemed that the work here was still going on in an orderly manner, and the trucks entering and exiting the spiral passage and the central hall were constantly flowing, transporting truckloads of earth and rock to the surface, and only then did they dig such a huge underground crater; Stout cables, which are brought underground from the distribution stations in the above-ground complex, provide power to a large number of equipment scattered throughout the country; Technicians transferred from the "Rome General Directorate" of the KGB brainstormed at the seminar to determine the next direction of facility construction and research......

Then the tragedy broke out, so that all this qiē was annihilated in the endless river of time.

This was gradually determined in the investigation, and the gains were not small, but this made Long Yun fall into new confusion.

Gradually collecting a backpack full of investigation materials along the way, he pondered on the way back to the surface through the Guò tunnel, no matter what, the "giant tree" was undoubtedly the cause of the tragedy of the "Rome" base, but the reason was not known, since it was not caused by a research accident in the base, then what could be the cause.

This question, not only was he very curious, but it was conceivable that the "General Administration of Rome" and even the general secretary were eager to answer it, but now there was no conclusion, which made Long Yun feel troubled for a while, and then he thought of the first paper material found in the underground base before, and a large number of "double opaz" in a certain room.

Oh, and it wasn't without warning before the tragedy at the "Rome" base.

Climbing all the way to the emergency passage and putting the collected documents and items outside the "black wall" airlock door, Long Yun's thinking continued, although he couldn't figure out what was going on with those mysterious items that were not in the right era and had even wrong characteristics, but it was obvious that these things could not have been "thrown away by the spies intentionally or unintentionally", at least the age was not the right number at all. On the other hand, although the KGB personnel found these items, they failed to discover this simple fact, to say that the detectives' professional skills were insufficient, Long Yun thought that this was basically impossible, so he naturally assumed that the moment when these things appeared was quite close to the time when the tragedy occurred at the "Rome" base.

While thinking, he returned to the underground base, and since he had this rough judgment, Long Yun entered the room where the "mysterious items" were displayed again and carefully examined a small part of the items.

From his own point of view, it is obvious that these things only appeared in the United States in the eighties and nineties, but now they are placed in a secret base of the Soviet Union that has been sealed in the dust for more than ten years, which looks really abrupt; In order to have a chance to test his judgment and preserve some evidence, he selected a few small, lightweight, and obvious features from the items on the bench, and packed a Zippo lighter in a soft plastic bag, a small piece of slightly damaged logic circuitry, a clear plastic handle cone, a hard drive disassembled from a "COMPAQ" computer, and an alloy wrench that didn't look weird.

Long Yun packed all these things into his backpack, and he had already made up his mind to keep them for study and not submit them to the KGB department for the time being.

American goods from inexplicable times, these items appeared in the "dead city", which is obviously very unreasonable, and it is said that Long Yun should record this situation in detail, and then report it to the "General Administration of Rome" and other aspects. However, as early as when he discovered these mysterious objects, he vaguely felt that something was wrong, or subconsciously believed that there was no direct connection between the tragedy of the "dead city" and these objects; Going a step further, Long Yun actually noticed that these seemed to have undergone a "double opaz" that had gone through a time and space disorder, and the clues revealed were likely to be related to his crossing, so this required absolute secrecy rather than rashly letting the outside world know.

After all, the so-called "time travel", operating in a parallel world as Viktor Rezenov, can be said to be Long Yun's biggest secret in this time and space, and he will subconsciously protect himself now, and he is unwilling to let anything that may reveal this secret be known.

While busy, while thinking, by the time the entire underground base was basically explored, and the related items were almost collected, a whole day had passed.

Because he came to investigate alone, and there were no companions around him to discuss, Long Yun could only rely on his own knowledge and judgment to deal with it, he went back and forth between the underground space and the MAZ off-road truck, and filled the temporarily installed compartment behind the truck with investigation evidence. After doing this, seeing that the sky had darkened, he returned to the tent with his AKS74 on his back to rest for a while, planning to drive away early the next morning.

When night fell, the "dead city", which was already empty, was even darker and more silent at this time, and the cold wind that had been howling for several days almost stopped, so that Long Yun could not hear a sound in his ears. (To be continued......)
