Ten minutes had passed since Chen Lei and Xu Bintang were under extremely low temperatures, and the two began to run together, not only in a vain attempt to escape from this area, but also in the hope of heating up their bodies through exercise.

However, no matter how much I ran, I couldn't find an exit to leave, and my body temperature didn't get hotter with running.

"Forget it, Bintang! I suddenly had an idea. ”

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

"Damn it, I usually take a walk, you and I are not used to carrying mobile phones, and now we can't even call for help, but I remember that Ye Zeng brought a mobile phone, he will definitely contact people, so, let's continue to move, we must not freeze to death here, we will definitely be able to get out if we work hard!"

"Are you sure the call will go out?

Chen Lei sighed and said, "I'm afraid we have encountered another supernatural event, everything here reminds me of that magical cake!"

Xu Bintang was stunned, "Won't it?!"

"How could not, can you explain everything here scientifically?"

Chen Lei shuddered twice, and continued with a trilling voice: "Before you came in, did you see the situation of those four high school students?" They must have been in the same environment as we are now, cold and desperate, we were outside, less than a meter away from them, we could see them and hear their voices, but they couldn't see us and we couldn't hear us, I tried to save them, but as soon as I stretched out my hand, I couldn't touch each other at all, and the moment my hand touched this area, the distance that was originally visible to the naked eye was instantly magnified!"

"You must be like me, feeling incredible, right? Before I came in, I visually measured the range of the four high school students walking around in a circle, but it was only four by five meters, a range of twenty square meters, but what about the actual space here? It seems to be infinite, we have walked for so long, and we haven't even seen the faces of other people!"

"Speaking of which, you and I are extremely lucky, I'm sure you and I can meet inside, this is already a low-probability event. ”

"But I'm afraid that luck is nothing more, not to mention that we will never be able to get out, but there is a way to get out, and we don't have that time, we will freeze to death in it. As for the rescue, if the people who come here do not know the information here, they will come to the same fate as we do. Even if we had the information, how long would it take to find a way to rescue us, and how long would we be able to 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 decisions, so he asked, "So, what do you want to do?"

"I'm thinking, when you and I are about to die, why don't you do your last mission, study here, and spread the results!"

Chen Lei took out a voice recorder from his shirt pocket and said, "It turns out that the people inside can transmit sound to the outside! Record the results of our internal observations, and then play them, so that people outside the area can crack this area according to the clues we provide!"

Seeing Xu Bintang nodding in agreement, Chen Lei smiled and said, "Then should we give our project a name according to the past practice?"

"When I ran around before, I remembered a story, do you know that King Zhou Wen painted the ground as a prison?"

Xu Bintang is naturally no stranger, after all, although the two are both physicists, they are also lovers of literature, history and biography, and their friendship comes more from literary exchanges than from the collision between physics.

Painting the ground as a prison, it tells the story of what happened between Bukit and King Wen of Zhou.

Bukit was a dutiful son who made a living by collecting firewood. One day he came to Xiqi City to sell firewood. At the south gate, I was catching up with King Wen's car passing by. Due to the narrowness of the market, when the firewood was replaced, he did not know that he collapsed, and when he turned the flat shoulder, he beat the sergeant Wang Xiang'er who was guarding the door, and he was killed immediately, and he was taken to see King Wen. King Wen said, "Since Bukit killed the king, he should resist his fate." He ordered to draw a circle on the ground of the south gate to make a cell, erect a log to make a jailer, and locked Bukit up.

Three days later, the doctor Sanyisheng passed by the south gate and saw Bukit crying bitterly, so he asked him: "It is natural for a person to kill to pay for his life." Why are you crying?"

Wu Ji said: "The villain's mother is 70 years old, she only has one child with me, and the villain has no wife, and the mother is lonely, afraid that she will starve to death!"

San Yisheng entered the city and entered the palace to see King Wen, saying, "It is better to let Wu Ji go home first, and wait for him to finish supporting his mother, and then come to repay the king's life." I don't know how?" King Wen approved and let Bukit go home.

Painting the ground as a prison means drawing a circle on the ground as a prison, and it is only allowed to move within a designated area. This allusion reflects the sincerity of ancient gentlemen.

Thinking of the situation of the two of them now, aren't they confined to this space and can't get out?

Xu Bintang didn't expect his old friend to be so optimistic at this time, but he talked about literature and history with himself again, and suddenly smiled: "When, still engage in this flower, it's up to you, you can name it however you like!"

Chen Lei also smiled: "Na, painting the ground is a prison, and the painting is still an ice prison, so the research topic is called painting the ice prison." ”

In order to prevent other people from coming in, I have repeated the sentence "Don't come in, listen to the recording" at intervals, and if you add anything after I have finished speaking, I will also insert this sentence between your speeches, in short, no one else can fall into this dangerous situation in any case. ”

"Then it's on!" Chen Lei saw his old friend nodding, pressed the record button, and began to record:

"This area I call the painting ice prison, the observation results outside the area, the range is roughly 20 square meters, the length from the artificial lake rockery to the boulevard next to the flower bed, the width of my three people to stop the footprints to the periphery of the pavilion, I have used my feet to shovel the place where the three of us stopped, need to be carefully searched, to avoid crossing the boundary!

"The interior of the area is extremely treacherous, the space is endless, it seems to be boundless, you get lost when you enter, and the interior is a low-temperature environment, I have been in it for fifteen minutes, and my consciousness is slightly blurred, so I guess the ambient temperature is about minus 20 degrees Celsius. ”

"You can't see outside the zone, but you can transmit sound to the outside, and conversely, people outside the zone who can see inside the zone can't transmit sound to the inside of the zone. Summary: There is a one-way connection of sound, light and shadow in the inner and outer areas. ”

"Confirmed that the Ice Dungeon works on people, but does not verify that it can work on other creatures. ”

"Now verify whether the painting is effective against dead objects!" Chen Lei took off his watch and threw it forward, the watch was first in the sight of the two, and then suddenly disappeared.

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

"After experimentation, there is a high probability that this area will not be effective against dead objects, and you need to find my watch, leather shoes, and glasses outside the area to prove it. ”

Getting such a result, Chen Lei breathed a sigh of relief, if it really can't take effect on dead objects, then it proves that people can be rescued through tools and unmanned equipment, unless the inside and outside are also one-way for dead objects.

"Some of the characteristics of this area are the same as the indispensability of the cake, such as violating the thermodynamic theorem, there is no heat conduction inside and outside the area, which violates the theory of optics, and the outside sees the inside means that the light can pass through the area and reflect back to the human eye outside the area, indicating that for light, the inside and outside the area are connected in both directions, which is contrary to the inability to see the outside inside. and the situation of the infinite space inside, which cannot be explained by science, therefore, assuming that the sources of the two are the same, they can be combined with reference studies. ”

Recording this, Chen Lei's consciousness became more and more trance-like, calculating the time that he had been here for at least half an hour, theoretically, people have no thermal insulation measures, and they have been in an environment of minus 20 degrees Celsius for 30 minutes, which basically means that half of his feet have stepped into the ghost gate.

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

He likes literature, history, biography and literature, and suddenly remembered the description from the ice and fire: If you stay in the extremely cold temperature for a long time, you will dream quietly, dreaming of hot wine and warm campfires. It's hot, yes, there's nothing as hot as the cold anymore. But after a while, it will burrow into your body and fill your body, and after a short time you will have no strength to resist, longing to sit down and rest or take a nap, and it is said that in the end you will not feel any pain at all. You just feel weak and drowsy, and then everything fades away, and finally, like drowning in hot milk, it's peaceful and quiet.

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

"Lift... Rise... Heaven!" In a trance, Chen Lei heard his friend's voice.

"Heaven?" Chen Lei raised his head vigorously, and saw the still white clouds, he recalled that he liked to look up at the clouds when he was a child, those clouds of various shapes, like fish, like birds, like chicken legs, like cattle and sheep, even if it is not like anything, he can make up what he knows.

So now, what are the clouds in the sky like?

Chen Lei's eyes widened suddenly, and the clouds that were still in the sky were faintly made up.

Those two words are: Shen ??

No, Shen, omitted!

"Shen Luo!" Chen Lei recorded his last sentence, pressed the end button with all his might, and pressed the loop play button before he lost his last consciousness at the dying moment.
