The remaining explanation is that the vibration source is not within the hearing frequency range of the human body.

In other words, Feng Zilong and Zhao Min's knowledge of this aspect is simply zero, and it is no longer possible to find out why from this aspect.

At the same time, Zhao Min also remembered a question, that is, before she and Feng Zilong climbed this slope, they saw that there were a few trees growing on this slope, but at this time, except for stones or stones, there was not even grass on such a large slope, let alone tall trees.

Where did you go with those trees you saw earlier? Could it be that what you see is an illusion at all?

Yes, it's an illusion.

Zhao Min comforted himself while thinking. Now, apart from this, she, like Feng Zilong, can't find a good way to convince herself. After all, it's so strange here, it's clear that the terrorists are close at hand, but they are like an interface between them, only the people inside can see the outside, and the people outside can't see the inside.

If this is the case, then as long as you go to the foot of the slope, pull one terrorist in and kill it, and then pull another one in, and so on, how long it takes, you can wipe out all the terrorists here. But now the question in front of her and Feng Zilong is - is it possible to see the outside from the inside, but not from the outside?

It should be impossible to say that those terrorists are pretending, because they are so far away from Feng Zilong and Zhao Min, if they really saw Feng Zilong and Zhao Min, it would be fake not to shoot and kill, because Feng Zilong and Zhao Min killed several of their accomplices.

But they never shot and killed, which means that they should really not be able to see Feng Zilong and Zhao Min inside.

Feng Zilong and Zhao Min are now thinking about how to pull a terrorist in to try whether the other party is really invisible or fake, if one is pulled in, and the others have not reacted, it means that the outside really can't see the inside. In this way, he and Zhao Min can let go of their hands and feet to pull in the terrorists who walked to the edge of the rocky slope and kill them.

It took about twenty minutes to catch up with Feng Zilong, who was standing at the foot of the rocky slope at this time, studying what the terrorists in front of him were doing very carefully. He and the terrorist were only separated by a thin membrane, but the interesting thing was that Feng Zilong saw him really, but he didn't see Feng Zilong at all, because Feng Zilong punched him, but he turned around and saw nothing, only a gentle slope in front of him, which was full of rocks and sparsely growing a few large trees.

"You punched him?" When Feng Zilong heard the words, he turned around, nodded, and said, "He really can't see me." Zhao Min said I saw it, and at the same time told him that in the space where he was, as long as the distance was more than five meters, he couldn't hear the other party, Feng Zilong said No wonder he called her just now She didn't react at all, it turned out to be like this.

But somehow, the terrorist couldn't get through the film. Feng Zilong sneered at him, and when he just approached, he suddenly grabbed the handle of his gun, pulled it inside, and the gun was in Feng Zilong's hand, and the terrorist was like touching a steel plate, and he got a few big green bags on his head, sat on the ground baldly, and stared inside.

"Let me slap him." Zhao Min said, slapping the past, horn, the person was beaten by her and didn't get up for half a day.

Just now he was punched, the gun was confiscated, and at this moment he was slapped again, which made him angry and scolded his mother. But he was beaten and robbed, but he didn't even know what the person who beat him and robbed him looked like. When encountering this kind of thing, no one will believe it unless you experience it yourself. It's like at this moment, he said that he was beaten and the gun was snatched away, and he didn't believe it at all.

"Head, my gun was robbed."

A person with a particularly vicious face shook his head: "You can coax others, but you can't coax me, you said that your gun was robbed, just a few of us here, dare to ask who robbed your gun?" ”

"I don't know."

"Don't know?" The man's eyes were staring at him like sharp blades, "You're talking nonsense with your eyes open, aren't you?" In broad daylight, who would dare to snatch your gun? ”

"Head, I really don't know."

"Where was your gun robbed?"

"This is it."

"This is it, are you dizzy, there is not even a ghost here, who will snatch your gun?"

Feng Zilong and Zhao Min were only three or four meters away from the little leader, and he and Zhao Min could hear their conversation clearly, but he and Zhao Min had no intention of continuing to grab their guns and beat them.

"This is the rocky slope that the gods don't dare to go up on, you said that your gun was robbed, could it be that the ghosts and gods on the rocks are really resurrected again?" As he spoke, he looked back and forth on the rocky slope for a long time before locking his eyes on the person who was punched by Feng Zilong, "I wonder if you peed on the stones on this rocky slope?" I have heard the older generation of people say that the stones on this rocky slope cannot be touched, cannot sit on, and cannot pee and drench, and if you do these things, you will be punished, and if you say that you have been beaten, you must have done something sorry for the ghosts and gods on this rocky slope, so you will be retaliated by them. ”
