With a "squeak", the heavy metal door opened.

I didn't expect it to be so easy to open the door, Long Yun pushed the door open at a small angle, observed the lock on the side of the door, and found that this door used an electronic lock that was very fashionable more than ten years ago.

The electronic magnetic lock was a novelty that must have been considered super reliable and impossible to crack at the time, but who would have thought that all the electronic devices here would completely fail overnight, and even the backup power supply would be destroyed by a mysterious force, and no matter how advanced the electronic lock was, it could only become an ornament? Seeing that the door opened so lightly, saving him the effort of trying to climb the high wall, Long Yun was about to step into the dimly lit doorway, but suddenly stopped.

Right in front of him, in the dim hallway on the inside of the door, there was a long line of blurred shoe prints on the ground that had been deposited with a layer of dust.

――？！

The scene in front of him made his eyes widen and he stood on the spot.

In front of Long Yun, a string of shoe prints that were completely ordinary and could not be more ordinary made him extremely frightened all of a sudden, and he stood in place in a daze without moving.

Shoe prints?

-- What is this?

For a moment, Long Yun almost wondered if he had seen some hallucination; When he finally broke free from the shock, he slowly leaned down to examine the shoe prints on the ground, and even reached out to touch the dusty rough ground to make sure they were real.

But...... But this is ridiculous, how is this possible?

Barely regaining the slightest ability to think, Long Yun's first reaction was, could this be the traces left by the staff back then?

"The traces of history have been discovered". This idea is a very bizarre idea, but it is also a reasonable assumption. But he looked around a little and immediately dismissed this speculation. It's absolutely impossible.

The reason for this certainty is that it is assumed from the situation at the scene that the sedimentary sand that left shoe prints in the door leaf was apparently blown in by the wind from the outside and deposited on the ground over the years. In this way, there are two doubts in the speculation just now: first, when the base is operating normally, it should not be left unattended and abandoned to the point that there is a thick layer of sand; Secondly, even if there was sand deposited here at that time, there were shoe prints of passers-by. This means that the door opening is not a completely enclosed space, and it is impossible for any sand imprint to remain for more than ten years in the environment of wind and sand.

But......

The more he ruled out this possibility, Long Yun's heart was furious, if it wasn't someone who stayed back then, then what was going on?

Then he began to wonder again, did he walk in circles and see the shoe prints he left before?

This idea of self-denial is, of course, absurd, but in all fairness, it is probably the same for anyone in his situation; With a hint of fantasy, Long Yun stood up and looked at the soles of his shoes. The pattern is not consistent with the shoe print on the ground, so this possibility is completely ruled out.

In the vast Gobi in the heart of the Soviet Union. The "dead city", which has been abandoned for many years, the place where anyone who approaches it will mysteriously die violently, has clearly recognizable shoe prints, which is simply extremely weird.

Whose shoe print would that be?

Who is it that would appear in this forbidden land of mankind?

A series of doubts and shocks made Long Yun, who was in a daze, a little dizzy, he entered the door completely unconsciously, and after closing the metal door, he leaned against the wall inside the door and gasped.

After a long time, he gradually sobered up from the extreme horror, and gradually clarified his thoughts and began to try to think about this strange thing. Picking up the kettle and taking two sips of water, countless thoughts turned through his mind, Long Yun didn't understand at first what the origin of this person who entered the "dead city" before him and left shoe prints; But as a speculation gradually surfaced, he couldn't help but secretly gasp.

If it is said that he was able to step into the "dead city" because he was not affected by mysterious powers because he possessed superpowers, and now he found signs of other people's existence here, then the only reasonable explanation can only be-

The mysterious person who entered here before him is also a person who is not affected by mysterious forces and also has superpowers.

But......

But is this possible......

Subconsciously shook his head, as if he was confused by his own thoughts, Long Yun remembered his previous experience in the superpower test at the KGB headquarters, could it be that there were really people in the Soviet Union who had the same spiritual superpowers as himself and were not known?

Regardless of whether such a person exists or not, at least in this parallel world, there is no official person who knows about mental superpowers, and I am still very sure of this.

Thinking of this, Long Yun subconsciously clenched the handle of the AKS74 gun in his hand, and he realized that there was already some kind of threat of unknown origin lurking in this dead and silent town he was in. It is very obvious that the mysterious person who entered the "dead city" before him, whoever he really is and how he learned about this place will never be someone sent by the Soviet Union, that is, the KGB; Naturally, then, this guy who can penetrate the barrier of mysterious power, his motive for infiltrating the "dead city" is very questionable.

What is this mysterious figure of unknown origin doing in the "Dead City"?

It won't be a good thing, that's simply a certainty.

Feeling his heart pounding in his chest, Long Yun barely calmed himself down first, the shocking discovery just now completely changed the situation of this secret operation - the original plan was to search and investigate in a no-man's land, but now it has become a hide-and-seek with an unknown mysterious opponent, but it is in this strange forbidden place of death, how can this not make people feel extremely nervous?

The discovery of traces of living people in what should have been an uninhabited "dead city" made Long Yun only feel that his hairs stood on end, and he unconsciously clenched the gun in his hand a little tighter.

But now he knew very well that where there was no backup, tension was of no use; Now you have to think for yourself and then act decisively. Fortunately, when I set off before, I carried the necessary weapons as a precaution, and now I have an AKS74 short assault rifle in good condition, which gives me a lot of confidence support, and if I encounter my opponent, I will not be beaten passively with my bare hands.

In this way, convincing himself to calm down, Long Yun finally began to make careful logical reasoning.

First of all, whoever left these shoe prints was, that person must have entered the place before him; And looking at the clarity of the footprints, one can even boldly speculate that these footprints will not last more than a day or two.

So in other words, the mysterious person who came here before him, no matter who he is, is likely to be still active in the "dead city" at this time? (To be continued......)
