It had been ten minutes since Chen Lei and Xu Bintang under the extreme low temperature. The two began to run together, trying to escape from this area, and hoped to heat up the body through exercise.

However, no matter how you run, you can't find the exit, and your body temperature does not get hotter with your running.

"Forget it, Bintang! I suddenly have an idea."

"Chen Lei, you can't give up! There is always a way to go out, at least you have to wait until someone comes to save us!"

"It's really damn. We don't get used to bringing our mobile phones when walking normally. Now we can't even call for help. But I remember that Ye Zeng brought his mobile phone and he would definitely contact people. So, we continue to move and must not freeze to death here. If we work hard, we will definitely get out!"

"Are you sure you can make a call? You just call. Do you think we can still get out?"

Chen Lei sighed and said, "We may have encountered another supernatural incident. Everything here reminds me of that magic cake!"

Xu Bintang was stunned, "No way?!"

"Why can't you? Can you explain everything here scientifically?"

Chen Lei shivered for a few times and continued with a tremolo, "Before coming in, did you see the situation of the four high school students? They must have been in the same environment as we are now, cold and desperate. At that time, we were outside, less than one meter away from them. We could see them and hear their voices, but they couldn't see us or hear our voices. I tried to save them, but when I reached out, I couldn't touch each other. The moment my hand touched this area, the distance that was originally visible to the naked eye was instantly amplified!"

"You must be the same as me, right? I've measured the range of the four high school students walking around in circles before I came in. It was only four by five meters, just twenty square meters, but what about the actual space here? It seemed infinite. We walked for so long and didn't even see the other people's faces!"

"Speaking of this, I am extremely lucky. I am sure you and I can meet you and I have already triggered a low-probability event."

"But I'm afraid that's all luck. Not to mention that we can never get out, we have a way to get out, and we don't have that time anymore, we will freeze to death. As for rescue, if the person who comes here doesn't know the information here, it will end up like us. Even if we know the information, how long will it take to find a way to rescue us? How long can we stay in such an environment?!"

"This..." Xu Bintang agreed with what Chen Lei said.

At the same time, Xu Bintang also felt that his old friend seemed to have made some decision, so he asked, "So, what do you want to do?"

"I'm thinking, when you and I are about to die, why not do your last mission, study here, and pass on the results!"

Chen Lei took out a recorder from his shirt pocket and said, "Facts have proved that the people inside can convey sounds to the outside! Record the results of our internal observations and play them, so that people outside the area can crack this area based on the clues we provide!"

Seeing Xu Bintang nodding in agreement, Chen Lei smiled and said, "So should we name our project according to previous practice?"

"When I was running before, I remembered a story. Do you know that King Wen of Zhou drew a land to prison?"

Xu Bintang is naturally familiar with it. After all, although the two are both physicists, they are also enthusiasts of literature, history and biography. Their friendship comes more from literary exchanges, rather than collisions between physics.

The plot is a prison, which tells the story of what happened between Wu Ji and King Wen of Zhou.

Wu Ji was a filial son who made a living by harvesting firewood. One day he came to Xiqi City to sell firewood. At the south gate, he was passing by with King Wen's carriage. Because the road in the city was narrow, one of the ends collapsed when he changed the shoulder pole. When he turned over the shoulder pole, he beat Wang Xianger, the sergeant guarding the gate, and was killed immediately.

He was taken to see King Wen. King Wen said, "If Wu Ji beat the king to death, it should be a duty." He ordered a circle to be used as a prison cell on the ground of the south gate, erected a piece of wood to be a prisoner, and locked up Wu Ji up.

Three days later, Doctor San Yisheng passed by the south gate and saw Wu Ji crying sadly, so he asked him: "It is natural to kill someone to pay for his life. Why do you cry?"

Bukit said: "The villain's mother is seventy years old. She only has me and the villain has no wife. She is alone and afraid she will starve to death!"

San Yisheng entered the city and came to see King Wen, and said, "It's better to let Wuji go home first, and then come to compensate the king's prime minister for his resignation. Don't know what?" King Wen was right and asked Wuji to go home.

Drawing a jail as a prison means drawing a circle on the ground as a prison, only allowing it to move within a specified range. This allusion reflects the trust and sincerity of an ancient gentleman.

Thinking of the current situation of the two, aren’t they trapped in this space and unable to get out?

Xu Bintang didn't expect that his old friend would be so optimistic at this time, so he talked about literature and history with himself again. He immediately smiled and said, "When is it, you still have this flower head! It's up to you, name it whatever you like!"

Chen Lei also smiled: "Nah, the drawing of the ground is a prison, and the drawing of the ice prison is still an ice prison. Then the research topic is called the drawing of the ice prison."

"In order to avoid other people coming in, you repeatedly remind me of the intervals I said: "Don't come in, listen to the recording after listening to the recording." If you add something after I finish speaking, I will insert this sentence between your speeches. In short, no matter what, no one else can fall into this dangerous place."

"Then it's starting!" Chen Lei nodded when he saw his old friend, pressed the recording button to start recording:

"I call this area a painting ice priest. The observation results outside the area are roughly 20 square meters. The length starts from the artificial lake and rockery to the flower bed next to the tree-lined avenue. The width starts from the three of us stopping and footprints to the outside of the pavilion. I have shoveled the three of us stopping with our feet. We need to search carefully to avoid crossing the boundary! This range extends outward for ten meters to be warned, and no one should enter!"

"The area is extremely dangerous, the space is endless, and it seems to be boundless. When you enter, you will be lost. There is a low temperature environment inside. It has been fifteen minutes since I entered it, and my consciousness is a little blurred, so I guess the ambient temperature is around minus twenty degrees Celsius."

"The outside of the area cannot be seen inside the area, but it can conduct sound to the outside. Conversely, people inside the area can be seen outside the area, but it cannot conduct sound to the inside of the area. Summarize the existence of sound and unidirectional connection between light and shadow in the inner and outer areas."

"Confirm that the ice bars in the drawing are effective for people, and it has not verified whether they can be effective for other creatures."

"Now verify whether the drawing of the ground is effective for dead objects!" Chen Lei said that, he took off his watch and threw it forward. The watch was first in the sight of the two of them, and then suddenly disappeared.

Chen Lei then threw his glasses, left and right leather shoes into the left and backwards in turn, and got the same result.

"After experiments, it is likely that this area will not be effective for dead objects. You need to find my watch, leather shoes, and glasses outside the area to prove it."

With such a result, Chen Lei breathed a sigh of relief. If it really cannot take effect on dead objects, it will prove that people can be rescued through tools and unmanned equipment, unless the internal and external dead objects are also unidirectional.

"Some characteristics in this area are the same as the indispensableness of the cake, such as violating the thermodynamic theorem, without heat conduction inside and outside the area, and violating optical theory. Seeing the inside outside means that light can pass through this area and reflect back to the eyes of people outside outside the area, indicating that for light, the inside and outside the area is bidirectional, which is contrary to the inability to see the outside inside. And the situation of the infinite space inside cannot be explained by science. Therefore, assuming that the sources of the two are consistent, we can combine reference research."

After recording this, Chen Lei became more and more dazed. He calculated the time he had been here for at least half an hour. In theory, without insulation measures, he was in an environment of minus 20 degrees Celsius for 30 minutes, which basically means that half of his foot had already stepped into the gates of hell.

He felt his body was a little hot, and as a physicist he knew that he was already in a state of "anomalous heat".

He who likes literature, history, biography and literature suddenly remembers the description from Ice and Fire:

If you stay in the extremely cold temperature for a long time, you will dream quietly, dream of hot wine and warm campfires.

Very hot, yes, nothing is as hot as the cold anymore.

But in just a moment, it will penetrate into you and fill your body. After a short while, you will not have the strength to resist and are eager to sit down and rest or take a nap. It is said that at the end it is completely uninjured.

You are just weak and drowsy, and then everything fades away, and finally, as if drowned in hot milk, peaceful and quiet.

As if verified this description, Chen Lei began to unbutton his shirt collar and tried to expose his chest and abdomen. He began to take off his pants, socks, and underwear.

"Raise...look...in the sky!" Chen Lei heard the voice of his friend in a trance.

"In the sky?" Chen Lei looked up hard, and he saw the still white cloud. When he recalled that he liked to look up at the clouds when he was a child, there were clouds of various shapes, including fish, birds, chicken legs, cattle and sheep. Even if he didn't look like anything, he could even imagine what he knew.

So what are the clouds in the sky now?

Chen Lei suddenly opened his eyes wide, and the still clouds in the sky vaguely formed the word.

Those two words are: Shen?

No, Shen, Lue!
