Liu Yaoxi slowly opened his eyes, everything in front of him was completely the same as before, the difference was that there were no four figures outside the glass door.

Liu Yaoxi looked left and right, and the other three people also opened their eyes one after another. The four of them looked at each other a few times, but none of them spoke, and no one broke the silence.

I don't know when, Xia Mengyou grabbed Liu Yaoxi's left arm again. What slid over from Liu Yaoxi's left arm was Xia Mengyou's nervousness, worry, and a hint of fear.

Liu Yaoxi looked at Xia Mengyou, smiled at her dotingly, and told her with her eyes that it would be okay, even if it was dark here, they could all see each other's eyes.

Yun Feiyu and Ye Fenglan are okay, both of them are quite bold, and there are not too many waves in their hearts. Just glanced at each other, exchanged a look, read each other's hearts, and waited for the door to open.

After a while, the glass door in front of the four of them opened. The four of them didn't hesitate too much, didn't say a word, and took steps in unison.

The four of them walked and observed their surroundings. Just walked out for half a minute, Yun Feiyu suddenly ran to the side, stood by the cave wall, and looked carefully.

Finally, Ye Fenglan's voice broke the calm for the first time: "Yun Feiyu, what are you doing?" Ye Fenglan asked as she walked to Yun Feiyu's side.

Liu Yaoxi and Xia Mengyou didn't understand this operation, so they also followed.

"Look." Yun Feiyu touched the wall of the cave and said, "This wall is obviously different from what we saw a few minutes ago. ”

When Liu Yaoxi heard this, he also stepped forward, carefully observed the cave wall, and touched it with a serious face.

"See what?" Xia Mengyou saw Liu Yaoxi's serious face and couldn't help asking.

"Hmm......" Liu Yaoxi made a thoughtful gesture, turned his head, looked at Xia Mengyou and said, "I didn't see anything." ”

"Then you still look professional." Xia Mengyou slapped Liu Yaoxi angrily.

"You have to ask Yun Feiyu this question." Liu Yaoxi looked at Yun Feiyu with some grievances and said.

Yun Feiyu looked at Liu Yaoxi and Xia Mengyou and smiled helplessly, then looked at the cave wall and said, "Look at this cave wall, this tunnel, it is obvious that it was dug several years ago. "Yun Feiyu is really fantastic," their tunnel is not too decorated, it looks like it is actually just a simple cave, so you can see the soil here. ”

"I don't know you know any of this, do you?" Ye Fenglan couldn't help but boast.

"Just look at it when you're bored." Yun Feiyu smiled bitterly, and then continued to touch the cave wall while saying, "Although I only know a little bit about it, but, roughly ......" Yun Feiyu paused, swallowed his saliva, and said slowly, "We have indeed traveled to the future. ”

“……”

“……”

“……”

Silence, sudden silence, even the atmosphere became a little awkward.

"What's wrong with you?" Yun Feiyu turned to look at us and asked.

"Nothing." I smiled wryly and shook my head, "I just think, I'm still a little bit unconvinced." ”

"But the possibility is not ruled out, and it is also possible that the group of people did it on purpose." Xia Mengyou suddenly spoke, "Actually, we are still in a dream. ”

"Alas, don't guess, it's useless to guess." Ye Fenglan was a little impatient, and took a step away as she spoke, "Let's go, most of those people are waiting for us in front." ”

"One step at a time." Liu Yaoxi continued to walk forward as he spoke, and Xia Mengyou and Yun Feiyu immediately followed.

Just a few steps out, Liu Yaoxi suddenly seemed to remember something, raised his left hand and saw that the watch was still there! But the three needles no longer moved, no matter how Liu Yaoxi shook it, looking at it from a different angle, the three needles in the dial were still indifferent.

"Liu Yaoxi, what are you doing?" Xia Mengyou ran to Liu Yaoxi's side and asked.

"This watch, it's useless." Liu Yaoxi shook his left hand again, looked at it again and said.

"Aren't you talking nonsense, after 5 years, that thing can still be used?!" Ye Fenglan looked at Liu Yaoxi helplessly not far in front and said.

"That's right." Liu Yaoxi nodded, then pulled Xia Mengyou and continued to walk forward.

After walking for about five minutes, they finally came to a stone door, which was very similar to what they had seen "a few minutes ago", most likely the same door.

The four of them just stood in front of the door, waiting for what would look like behind the door. Will it be a lab? Or is it still the same as before, a villa? Or, is it a real futuristic world? The four of them couldn't help but make one hypothesis after another in their heads. The door didn't open, and they could go on in reverie.

"Boom!" There was a loud bang, and the four of them only felt that the surroundings suddenly shook a few times, and it was relatively strong.

"Holy!" Yun Feiyu scolded directly, "It's not going to collapse, is it?!" As soon as he finished speaking, the shaking stopped.

"It won't be so fast......" Ye Fenglan teased with a wry smile. After saying that, the door in front of the four of them was opened.

"It seems that it's just because this one hasn't been used for too long." Liu Yaoxi looked at Yun Feiyu and Ye Fenglan and said.

"Let's go." This time, Xia Mengyou walked in front.

Behind this door, there was still a passageway, but it was much darker, and it was almost impossible to reach out of sight. Xia Mengyou retreated without taking a few steps, choosing to walk side by side with Liu Yaoxi.

Compared to the passage on the other side of the door, the only difference was its width, which was obviously narrower, so they had to walk side by side. Liu Yaoxi and Xia Mengyou walked in front, followed by Yun Feiyu and Ye Fenglan.

"What kind of place is this, it's too dark." Xia Mengyou's tone was full of disgust, and some fear.

"Even if you don't have a few lights." Ye Fenglan complained.

"It shouldn't be long, just hold on for a while." Liu Yaoxi comforted. In fact, Liu Yaoxi didn't have much bottom in his heart, about what would happen, what he would see, or what he would hear.

This time it didn't take long to walk, only about two or three minutes away, and Liu Yaoxi could see the light in front of him.

"It's almost there." Liu Yaoxi turned his head and said to them.

"Hmm." "See." Yun Feiyu and Ye Fenglan replied.

"Let's go, it's too dark in here." Xia Mengyou put her arm around Liu Yaoxi and said as she walked.

The light grew closer and stronger, and finally, they stepped out of this dark passage. The sudden bright light forced them to cover their eyes and wait for their eyes to recover before they could see where they were.

This place, like the hemispherical hall before, is large, completely white, and gives an indescribable feeling.

"Where am I?" Liu Yaoxi exclaimed. As soon as the words fell, the door behind them was closed, and this scene did not seem to make them feel too frightened or surprised, and did not show any exaggerated expressions. Xia Mengyou's fear before was purely because of the darkness and the unknown.

"Always asking nonsense." Yun Feiyu responded.

"Cut, sigh." Liu Yaoxi also responded. After saying that, he touched the wall and walked out at the approximate location of the door they had entered.

"Hey! Liu Yaoxi, where are you going? Xia Mengyou saw that Liu Yaoxi left directly, so he shouted to him.

"I'll see how big this is." Liu Yaoxi had already walked out a few steps, "If you look at it with your eyes, you can't see it clearly." ”

"Oh." Xia Mengyou replied.

"I'll take a look too, it's more efficient" Yun Feiyu said as he set off from the opposite direction of Liu Yaoxi, and also touched the wall and left.

This place is said to be big and small, and Liu Yaoxi didn't walk long before he could feel that the walls were obviously bent. After walking for a while, the distance between Liu Yaoxi and Yun Feiyu had already begun to shrink. In the end, Yun Feiyu and Liu Yaoxi converged.

"This place, hemisphere." Yun Feiyu said.

"Well, at first I thought it was a cylinder. Later, it was discovered that the wall was not only curved from side to side, but also not straight up and down. Liu Yaoxi replied.

"Hey! How's it going? Ye Fenglan saw that Liu Yaoxi and Yun Feiyu had converged, so she shouted to them.

"It's pretty much clear." Yun Feiyu replied. After speaking, Yun Feiyu and Liu Yaoxi walked back.

"This place, hemispherical. The radius is about ten meters, which is quite large. Yun Feiyu said to Ye Fenglan and Xia Mengyou.

"The walls here are all white, probably to give us a feeling of being endless and trapped." Xia Mengyou looked around and said.

"Hmm." Liu Yaoxi also nodded, "This place, after looking at it for a long time, it is easy to have a sense of emptiness, and it is not a good thing to be completely white." ”

"It's been so long, it's time for those four to come." Ye Fenglan changed the topic.

"That's right." Liu Yaoxi said and looked at the door they had come in before...... However, they could no longer find the place where the door was.

"It's quite thoughtful." Yun Feiyu walked to the wall and touched the wall, "There is no trace at all." ”

"Indeed, I can't see it at all." Xia Mengyou stood a little farther away, looked at it, and said.

"So why are we going to wait now?" Ye Fenglan asked helplessly.

"No one came to us, and the four didn't come, so we had to wait." Liu Yaoxi replied helplessly.

"Looks like you're going to be bored if no one comes." A voice of vicissitudes suddenly appeared.

"Who?!" Yun Feiyu behaved very cautiously.

"It can't be an enemy." Liu Yaoxi smiled bitterly.

"This voice, who is 70 years old." Xia Mengyou guessed.

"That's right." The voice came out again, "I am indeed from 70 years, but I am not the future of you. ”

"Oh?" Ye Fenglan instinctively wondered.

"What about the other four?" Xia Mengyou asked first.

"You don't have to worry about that, you'll see them later." The old man replied.

"So what do we need to do?" Liu Yaoxi also asked directly to the point.

"You don't have to know this so quickly, we will tell you when we need your help."

"Then you mean you don't need us yet." Yun Feiyu said a word.

"Yes." None of the four expected him to answer so quickly and directly.

"So are we really going to wait now?" Ye Fenglan couldn't help asking, "You have to change places for us." ”

"Don't panic, don't you want to see those four?"

"Coming?" When Xia Mengyou heard this, she began to look around.

"Here we are." As soon as the sound of vicissitudes of life died down, the floor about five meters in front of them was opened up as a passageway. Then four beds the size of a hospital bed were raised, and one person was in each bed.

The four men looked at each other suspiciously, and trotted over.

Lying on the bed, it is indeed the future of them. It's just that the question in the minds of the four people has the same question: Why are they here? Shouldn't it have come in through the same door they had just passed?

The answers to these questions should only be known to the old man just now, or the four people in front of him. But now the four people in front of him are in a coma, and they don't know when they will wake up.

The four of them just stood in front of the bed, silent......
