Hang Yi didn't 'figure' out what was going on, he just felt as if he had been sucked into a huge whirlpool. When he came back to his senses, he found himself standing in a white world, with nothing around him, only the vast white 'color', unable to distinguish between heaven and earth - fortunately, he was not the only one who was here, but also a few classmates who had just gathered in the middle of the classroom.

"What is this place?" Lu Hua asked in a daze.

"I don't know." Hang Yi looked around and said, "It looks like another world." ”

"Another world? We're not going to die, are we? Lu Hua's face turned pale.

"Do you have a breath and a heartbeat, don't you feel it yourself?" Sun Yuchen walked over to them, "We didn't go to heaven so easily. ”

"It doesn't look like heaven here, either." Helenko looked left and right, frowning. "Heaven wouldn't be so bad."

"It's not heaven, it's not hell." Lei Ao continued their words, "We are in a wonderful space, and I suspect this is not the real world. ”

The eight people who had been sucked in together all gathered together, and everyone looked 'confused' and puzzled, and it was obvious that none of them realized what had just happened.

Suddenly, a voice came from afar: "Ah! You're here too?! ”

Everyone looked at each other and saw a 'girl' running towards them - Ni Yanan, who disappeared first.

Ni Yanan ran to everyone's side with a sigh of relief, she was cold just now, but now she hugged everyone as if she had seen a long-lost relative. She burst into tears and said, "Great, great! Finally someone is here...... I'm going crazy! ”

"Great?" Wei Wei raised her eyebrows and looked at Ni Yanan.

"No......" Ni Yanan realized that she had said the wrong thing, "I'm just, I'm so happy, please forgive me for not choosing my words." You don't know, I'm alone in this empty, pale and dreary world, and I'm about to collapse! ”

Lu Ping wondered: "Ni Yanan, we rushed over after hearing your screams, and there was only a minute or two between before and after - although it is very depressing here, you won't be unbearable so soon, right?" ”

"What? A minute or two? Ni Yanan said in surprise, "How is it possible?" I feel like I've been here for a long time! ”

Everyone looked at each other in amazement, and Hang Yi asked, "How long do you think you've stayed?" ”

"I don't know, maybe ...... A couple of hours. Ni Yanan said.

"A few hours? How can it be? Sun Yuchen frowned and said, "Delusion, right?" ”

"No, it can't be a delusion." Ni Yanan said firmly, "The best proof is that I am very hungry now. But I had breakfast in the morning. Based on that, I guess I've been here for three to four hours. ”

Everyone's eyes widened in astonishment. Wei Wei pointed to the watch on Ni Yanan's wrist and said, "Why 'estimate'? Aren't you wearing a watch? ”

Ni Yanan shook her head and said, "I don't know what the hell this place is—the watch has stopped moving since I came in." ”

Everyone was stunned and quickly looked at the time displayed on their watches or mobile phones—and sure enough, all the items that indicated the time stopped working.

"The time here...... Is it stationary? Sun Yuchen was amazed.

"I'm afraid it's not that time stands still, it's that time flows quite slowly." Helenke pondered, "Judging from what Ni Yanan said, it seems that one or two minutes outside is equal to a few hours here. ”

"Is there such a place in the world?" Lei Ao asked, scratching his head.

There was silence for a while. Lupin asked Ni Yanan, "What did you do during the hours you spent here – if you ever had it that long?" ”

Ni Yanan said: "I was very scared, I wanted to find an exit and leave this hellish place, but this place is as wide as the ocean, no matter which direction I walked, all I saw was an endless white 'color'......" She paused, "And I suspect that there is no real 'direction' here, no matter which direction you go, you will eventually return to the beginning - the evidence is that I have been walking in one direction at first and have not looked back, but just now I heard your voice and quickly found you." ”

"In other words, you're actually going around in circles?" Liu Yujia asked uneasily.

"That's pretty much it."

Wei Wei took a deep breath and said, "There is no 'time' here, and there is no 'direction', and I guess there is no 'exit'. It's a white 'colored' grave! ”

Wei Wei's words made everyone shudder. Hang Yi saw Lu Hua's brows furrowed, as if he was thinking about something, and asked, "What are you thinking, Lu Hua?" ”

Lu Hua slowly raised his head and said, "I remembered some events that I had seen in the book before, which were very similar to what we are experiencing now. ”

"What event?" Everyone looked at him.

"In 1975, there was an incredible disappearance in the Moscow subway. A metro train leaves Belorusskaya station and takes just over ten minutes to reach the next station. Who knew that within ten minutes, the subway full of passengers suddenly disappeared without a trace. After that, the police and metro management launched a carpet search of the metro lines throughout Moscow, but they never found the subway and the hundreds of passengers on the full train. These people mysteriously disappeared on the subway tracks. ”

"You say it's a real event?" Sun Yuchen frowned and asked in disbelief.

"Yes. There are many more similar incidents. Lu Hua continued, "In July 1999, about 100 members of the Church in Colombia, Central America, went to the top of Mount Arris to worship. Believing that August 1999 was the 'end of the world', these saints went up the mountain to pray collectively for God's salvation. Who knew that this group of disciples never came down after going up the mountain, and disappeared. The incident alarmed the Colombian government, who sent a large number of police officers to search around the summit of Arris, and sent helicopters. In the past month, the entire Sierra Nevada has been searched, but there is no trace.

"If these are just incidents, then what is happening in the Bermuda Triangle, known as the 'Devil's Sea', is even more difficult to explain. Countless planes, ships and people have gone missing in these waters. No one knows where these missing planes or ships have gone. Lu Hua paused slightly, "Moreover, these disappearances all have one thing in common, which is quite similar to the situation we encountered - they all disappeared without a trace in an instant. ”

Everyone stared at Lu Hua. Hang Yi asked, "What do you mean by saying so much?" ”

Lu Hua said with a pale face: "If the situation we encounter is of the same 'nature' as these disappearances...... I know where we are. ”

"Where?" Let's ask together.

Lu Hua swallowed: "We are in another space." ”

"Alternate space?" Everyone was shocked. Hang Yi asked, "What do you mean?" ”

"Another dimension is a mysterious place that exists outside the normal world, which can also be called an alternate dimension." Lu Hua said, "Just as we are facing now - the speed of time flow in another space is very slow, about one hour outside is equal to ten years here. ”

"How do you know?" Sun Yuchen asked.

"I read it in a scientific magazine."

"You're talking about 'science fiction' magazines?"

"No, it's a very rigorous scientific journal." Lu Hua emphasized, "Although the concept of extradimensional space often appears in science fiction and movies, scientists have long concluded that alien space does exist. ”

"Tell me, what's going on?" Lei Ao said with interest, as if he was not worried that he was in it.

"According to Einstein's concept of 'four-dimensional space-time' mentioned in General Relativity and Special Relativity, our universe is made up of time and space. The relationship between time and space is that in the structure of space, there is an additional time axis in addition to the three axes of length, width and height of ordinary three-dimensional space, and this time axis is an axis of imaginary values......"

"Oh, don't talk about these esoteric things." Lei Ao made a headache. "Say we understand."

"Well," Lu Hua concluded, "To put it simply, the interdimensional space is a 'parallel universe' hidden around the real world. This space is completely independent of the normal world, and only in some very special circumstances will the "door" to the other world be opened, and once people in the real world enter this "door", ......"

Speaking of this, Lu Hua stopped and bit his lip tightly. Hang Yi asked, "What's wrong?" Let's move on. ”

Lu Hua closed his eyes and hesitated for a long time before continuing: "Once you enter, you are enclosed in another space, and there is no way to leave. ”
