Niu Er was very frightened, he didn't know what happened, he only remembered a tall and big, can't see his face clearly, he buttoned his hat on a hot day, wore sunglasses, covered his mask, walked towards him like a fly, didn't listen to his drink at all, came up and couldn't help but say, he slapped his hand, and then, he felt that he was flying up and flying up, so frightened that he instinctively closed his eyes.

And when he opened his eyes again, he was surprised to find that he was floating, and his whole body was full of energy, and he couldn't feel any of the points, as if he was floating in mid-air.

However, he couldn't see far, just twenty or thirty centimeters away from his eyeballs, there was a transparent film that glowed, and outside the film, it was pitch black, there was no starlight, no moon, no sun, and no artificial light!

It's really black, and you can't see your fingers at all!

"You...... Who are you? What have you done to me? I ...... Where am I?" suddenly happened to Niu Er, a strange thing that was completely beyond his imagination, making Niu Er's scalp numb and his whole body trembling, since he was a child, he has never been so afraid.

"You...... Who are you? What have you done to me? I ...... Where am I?"

"You...... Who are you? What have you done to me? I ...... Where am I?"

"You...... Who are you? What have you done to me? I ...... Where am I?"

“……”

Countless voices, countless voices of his own, saying exactly the same thing as him, began to vibrate and echo in his ears over and over again.

If Niu Er had not forgotten the acoustic knowledge taught by the teacher in junior high school physics class, he should know at this time that this is a reflection phenomenon of sound, referred to as echo!

If he had studied in high school and listened carefully to high school physics classes, he would have understood that any echo has a certain time limit, and in a closed or semi-enclosed space, it will be reflected once or twice, two or three times at most, and it will slowly decay and eventually disappear.

If Niu Er has read a large number of popular science books, especially popular science books on physics and materials science, in the face of extremely slow attenuation, constantly echoing and lingering in his ears, the real "lingering sound", he must be able to realize the following two points:

1. I am currently in an extremely closed, or even completely closed, confined space where sound waves cannot be transmitted at all, but can only reflect oscillations back and forth in the internal space!

2. The material used to make this confined space is extremely special, almost completely does not absorb sound waves, but only reflects sound waves!

Unfortunately, Niu Er is just a student who only has a first Chinese, and the physics is extremely poor and all returned to the teacher, facing an ordinary acoustic phenomenon that is not surprising, but the reflection time of sound waves is many times longer, and the attenuation time is many times slower, completely stunned, frightened, completely surrounded by a boundless fear!

He didn't dare to speak anymore, because something terrible was learning from him, ravaging his ears over and over again with his own voice!

"Are you in hell or hell......? Could it be that the person just now was a soul seducer? He had done a lot of evil in the world, and the king of Hades couldn't see it, so he sent this soul seducer to hook my soul? Could it be that I am dead now? I just exist in the situation of breaking my soul?" Niu Er didn't dare to speak, but only dared to think in his heart.

However, when he thought about it, he thought that he might be dead, and only his soul was left, and suddenly his liver and gallbladder were torn, and his urine flowed out.

He raised his hand violently to pinch his face, but found that he could pinch it, and it hurt to pinch himself, and his face was still warm, still hot!

"I shouldn't be dead, I shouldn't be dead! I'm still alive! Dead people don't have temperature, and they don't feel pain......" Niu Er began to comfort himself, and subconsciously spoke up.

And so, a series of identical, demonic sounds, penetrated into his ears again, vibrating in his ears, echoing:

"I shouldn't be dead, I shouldn't be dead! I'm still alive! Dead people don't have temperature, and they don't feel pain......"

"I shouldn't be dead, I shouldn't be dead! I'm still alive! Dead people don't have temperature, and they don't feel pain......"

"I shouldn't be dead, I shouldn't be dead! I'm still alive! Dead people don't have temperature, and they don't feel pain......"

“……”

"What the hell is going on?Where am I?Who are you?What do you want to do with me?......" Niu Er had countless questions in his mind that he wanted to ask, but he didn't dare to ask. In the first two voices, "someone" has clearly told him:

No one will answer any of his questions! Anything he says will be slapped back again and again!

————————

Any fear and any shock has a certain duration, and after a long time, the fear and fear will become numb as soon as the fear and fear pass.

Especially when you know that you are safe for the time being, and no one wants to physically harm you immediately, this sudden fear will quickly disappear.

Niu Er was frightened, and after being scared for more than half an hour, the fear in his heart slowly disappeared.

At least not as scared as it was at first.

He began to observe, to study the place where he was "imprisoned".

Yes, he couldn't think of any word to describe his current situation other than "captivity".

First of all, there is no doubt that he is floating in a tight, airtight "cover".

It was a rectangular cover, tall, only a little taller than him, wide, only a little wider than him, and long, only a little longer than him. It feels like a coffin to him. It's just that the material of this coffin is not wood, but a transparent film that has never been seen before, exuding a faint fluorescence.

And he, not lying in a coffin, nor sleeping in a coffin, but like an astronaut in the space station, floating in the coffin. His feet, dangling, made no contact with the bottom plate of the coffin, the membrane at the bottom.

At the beginning, the cow's ears floating in the "coffin" did not dare to move at all, for fear that the transparent luminous film wrapped around him would be electrified, and as soon as he moved, as soon as his body touched the luminous film, he would be shocked, or fall into the luminous film, or tear the luminous film, and fall into the unfathomable outside, like the abyss of eighteen layers of hell.

But it's not an option to stay still. Maintaining a posture for a long time also made him feel very uncomfortable, itching all over his body, and wanted to scratch it with his hands.

After Niu Er felt that he couldn't stand it anymore and remained motionless, he began to try to reach out and touch the transparent membrane in front of him.

He first stretched out his right hand, then changed to his left hand, slowly, inch by inch, using the tip of his index finger to touch the glowing film in front of him.

Thirty centimeters, twenty centimeters, ten centimeters, five centimeters, three centimeters, two centimeters, one centimeter...... As the distance approached, Niu Er held his breath, and his heartbeat beat uncontrollably beat violently, in this life, except for the first time with a woman, I have never been so nervous!

The index finger finally touched the glowing film.

The first feeling of the cow's ear is that it is hard, very hard, like glass!

The second feeling was slippery, quite slippery, more slippery than any glass he'd ever seen!

He pressed his entire palm tightly against the glowing film, trying to climb up with the strength of his head so that his head could touch the top of the "coffin".

But he failed!

He couldn't borrow a little bit of strength at all. This luminous film is not slippery, it is 10,000 times "slippery" than any slippery object he has ever seen in reality!

If Niu Er had a certain knowledge of mechanics, he would definitely think of a theoretical concept of physics at this time:

Zero friction!

Or rather, absolutely smooth!

However, although you can't move up and down, you can move forward and backward, move left and right, and you can start.

As long as he reached forward and pushed the spatial membrane in front of him, his body would move backwards.

Or push the space membrane to the left, and his body will move to the right.

"Force and reaction!" At this time, Niu Er vaguely recalled the laws of Newtonian mechanics that the physics teacher had talked about in junior high school physics.

But there are three laws of Newtonian mechanics, and he has no idea which ones belong to them.
