This low-frequency noise is the most penetrating and can travel far away.

It feels like it's right above the head, but in fact, according to Zhang Zimin's judgment, it's at least above the 19th floor!

From this point on, everyone was nervous and their palms were sweaty.

Zhang Zimin was a little confused and frightened, and he could cause this kind of movement on the floor slab separated by a carpet a few floors away, at least because of the volume of Dwayne Johnson and landing from a height of nearly three meters.

What is reassuring is that the other party should not be a crawling monster, or rather, a monster that falls on all fours. Rather, it moves on two legs like a human.

That's a little better. Anyway, in Zhang Zimin's impression, crawling things are at the top of the food chain most of the time, and they are the most difficult things to deal with and almost have no shortcomings.

Zhang Zimin really doesn't know what to do now, since he doesn't know, of course he continues to pretend to be dead and silent.

Fortunately, one thing is right, this ghost thing is on the 20th or 21st floor, which is the cusp of Zhang Zimin's designation as "today's bloody gas has not dissipated for the time being".

In this way, in a cold sweat, my breathing became very tight, and I couldn't see anything in the dark, I persevered until about 11 o'clock.

It was quiet all the time, and the building was carpeted, which made it difficult to catch the general movements.

Until 11:10, there was another relatively large and low-frequency movement.

It is clearer than last time, so Zhang Zimin analyzed: The previous one should have appeared on the 21st floor. And this time on the 20th floor?

This time it's more like it's right over everyone's heads. As a result, the frightened young man around him couldn't stand it anymore, and thought: The monster is coming, and if you don't run, you will die.

Her uncle suspects that the monster has locked on the four people here, and if he escapes decisively, there will be a chance of survival, because the three people who stay here are the monster's biggest targets, and the monster will most likely not give up the three here in order to chase one.

In addition, her uncle saw that Zhang Zimin no longer had a shotgun in his hand, and his deterrent effect was greatly reduced. At this point, he didn't even bother to say anything, and suddenly exerted his strength without saying a word, and escaped from under Zhang Zimin's table. Run quickly towards the entrance of the building in the direction of the security gate.

Zhang Zimin wanted to tell him not to run, but he also knew that this was the most useless nonsense at the moment, and on the contrary, he would make movements and increase variables.

So Zhang Zimin chose not to say a word and continued to be silent!

The otaku Xue Xiang is still heartless, although he heard some movements, but this Nima is not something that Xue Xiang can change. He didn't even care about Zhang Zimin's life or death, let alone other people, so he still didn't say anything, he just wanted to hide until he was old, and quietly hugged the little girl to keep her warm, and at the same time raised his hand to cover the little girl's mouth.

At this point, there was no movement except for the young man running.

Branch——

In the distance, there was the sound of the security door being pushed open in the silent darkness.

Branch——

The security gate closes automatically.

Knock Knock –

Then there was the echo of footsteps in the silent corridors.

Zhang Zimin was even more nervous, and silently changed to a strengthened slingshot in his hand (double rubber band).

This kind of slingshot has not been trained in ordinary times, and it is very difficult, and the way to control it is another kind of knowledge, even with Zhang Zimin's strength, it will be a challenge to quickly expand the consummation.

Therefore, the real combat efficiency has yet to be tested, but it is a last resort, and now we must be ready for hard fighting.

It is inevitable that the thrust of the slingshot is smaller and easier to control, so it is really significantly easier for non-professional people to play slingshots with a limited width of the rubber band (to reduce the thrust), or to replace the mud bullet with a heavier steel ball (to reduce the thrust in disguise).

It's just that the steel ball is more powerful under normal conditions, and it is easy to get into trouble if it is not well controlled, and it is easy to scrap your palm when you make a mistake, and it is more expensive than mud bombs, so there are not too many people who usually play with steel balls.

While thinking about it, there was finally movement again, also in the corridor. The speed was very fast, and the resonance of the sound showed that it was at least three to four times the size of the little girl's uncle.

Zhang Zimin concentrated his perception: Judging from the sound, this ghost thing stayed at the entrance of the security gate on the 16th floor for a while, but finally did not come in.

followed by a stronger and faster movement, as if she was chasing her uncle.

At some point, there was no sound again.

After a while, her uncle had already run out of the lobby of the office building, and in fact there was some movement in front of the square in the silence.

I thought he could get away!

But the form changed again, and suddenly there was a very sharp noise. It was as if something had broken through the glass wall of the building from about the seventh floor.

The reason why Zhang Zimin judged that it was about the seventh floor was judged based on the speed of free fall and then the interval between listening to the heavy objects falling on the square.

"Unless it's a suicide, it can land from the seventh floor, its organization has been strengthened to the point of terror!"

Zhang Zimin thought so in his heart.

Then, in the silence of the night, her uncle's rather miserable cry "Ahhh

There was only one sound, no more, and everything was calm!

It's not a perfect job, and it's a little hard to explain to Quinlan. But that's it, Zhang Zimin will never think much about this problem, and will only wait to solve the sequelae caused by it. Nothing else is the point.

At the same time, Zhang Zimin knew that there should be no more danger tonight.

This is because there is induction, and there is movement in the distance outside the office building. It seems that it began to parade in the dark, and the direction of its journey is probably the same as the old post and telecommunications community.

When I looked up at my watch, it was not yet twelve o'clock.

Zhang Zimin was afraid that he would forget some details after sleeping, so he took out a pen and took an A4 piece of paper and began to write blindly:

The rescue mission was basically successful but the situation has changed, and tonight the rescue team was trapped on the 16th floor of "Zhujiazhuang", feeling and even facing the threat that has been in close proximity.

After analysis, it has a special strengthening organization, which is more intelligent and sensitive than ordinary zombies. It is now almost certain that his sensitivity to noise and gore is in the category of corpses, and there is no mutation. It's a key point within a point.

In addition, it is similar to a zombie, and has a fixed preference (range of activity), but this thing does not have a fixed time every day, and the time it approaches the base seems to be advanced every day.

Well, I still think that "daily advance" is still one of the rules, and it is a law that can be used, but it still needs to be observed, Xu Rulin's state, maybe it is the main skill to defeat this monster.

Putting together the entire timeline of today, I suspect that the monster's lair is in this building, which is a bit unscientific considering that a cobra can survive so long in a building on the cusp of the storm.

Then this proves in turn: this monster has super strong tissue, but it must have a huge flaw in order to be exploited by cobras.

Combined with my earlier guess, based on Quinlan's reaction to light, I'm pretty much sure that this monster's nemesis is Daylight, which is supposed to be its hardware-level vulnerability.

These discoveries have made me feel a little more at ease now that winter is approaching. I don't have a tactic yet, but I'm trying not to let this monster survive the winter. Either you die or I finish!

Cobra is a very insidious and shrewd person, but unfortunately he didn't die, and today's sniping failure against him was not my mistake, but that he was too treacherous.

Even if he is now the commander of the light pole, he is still a great threat, and subconsciously I know that such a person will be at the top of the food chain no matter where he is, and he will always find an opportunity to hunt others and take power. It's his talent!

The second regret of not catching the cobra is that he must have been so clever that he must have a log, he has been in the same room with the monster for almost a long time, and with his shrewdness, he must have summarized many characteristics and laws of the monster.

Obtaining his journal can greatly increase the success rate of our monster hunting, but unfortunately it is not obtained.

On the evening of November 20, it was very cold and distraught, and Zhang Zimin, the people's postal officer, left a message at the temporary hiding point......
