Professor Xia was just about to chase after him, when the general and the beautiful woman arrived at the door, and the stone gate closed. The guards then closed their halberds and crossed them in a sign of majesty.

It was only a blink of an eye, and they were like a gust of wind, and it was too late for us to arrive.

"How can these two gods run so fast, it's like a gust of wind." Lingxin was amazed.

"Lingxin, our top priority now is to find a way to get out and recover that notebook." Professor Xia patted her on the shoulder and said.

However, the two powerful, deep-eyed soldiers in front of us were like two statues, and their expressions were as dead as the atmosphere of this dungeon.

I picked up a piece of gravel from the ground and knocked it on the wall, and the two soldiers turned their heads to look. They were still quite wary of the wind and grass, but after one glance, they turned their heads and continued to look straight ahead.

"Safety! Let's look and see if there's any mechanism on the wall. I reminded them.

"Hmm." They both nodded in agreement.

There must be a door to match it, otherwise what should I do if I enter and exit, and this underground palace is still under construction.

Then I suddenly remembered that when the group came in, the door seemed to be open all the time, and it was closed only after they had gone out.

In order not to make too much noise, we carefully searched the two walls next to the door.

The walls of this underground palace are made of green bricks, and a layer of white colloidal paste is used in the middle, which is staggered and stacked on top of each other, until it reaches the top of the underground palace. Due to the light, I couldn't see it further up, and I couldn't tell how tall it was.

Although we had passed through here when we came before, the dungeon was already badly damaged by then, so I couldn't tell the key to opening this stone door.

"Sen, have you noticed?" Professor Xia inquired about me after some inquiry.

He was an archaeologist, and no one knew the structure of the tomb better than he did, but he asked me.

I was a little "flattered" by him like this.

"No, these two walls are too clean." I shook my head and said.

"I didn't find out either." Lingxin looked at the two of us and said.

"You two don't look at me, I really can't help it." Seeing that they were still pinning their hopes on me, I emphasized.

At this time, I thought that it would be nice if my father was here, he would be proficient in Qimen Dunjia, but I was still not proficient in the arts.

Thinking of this, I can't help but worry that if I really can't go back, he will be the only one left in the family, and he will go crazy.

Examples such as "a few days in the cave, a thousand years in the world" seem to be written in the wild history, but this is also something that worries me.

I'm worried about this, but for now, I can only take it one step at a time. No one can change what has happened, they can only accept it.

It was at this moment that Lingxin walked up to the guard and waved her hand to try it, but the soldier took her for air.

Then something dramatic happened, Lingxin reached out to touch his armor, but her whole finger was completely sunk in.

"Dad, Sen. Come and see, it's so weird. Lingxin exclaimed.

I couldn't believe that the two of them were in front of us like projections, and they looked so real and without the slightest flaw. From this, I seem to believe that this is the case with all the life that exists here.

"Uncle Xia, what's the explanation?" I looked at him and asked.

He frowned and thought for a moment, but then shook his head and said, "All this is unusual, judging from my experience over the years and the information I have, we have entered a space that has never been seen before. ”

"Is it the outside world?" I blurted out.

"You know?" Professor Xia couldn't suppress his surprise and said in great confusion.

I can't tell him about this "outside world" that this is the plot of that dream, and that I proposed it. Although I don't know how different what he said is from my existence, everything we experience is not in harmony with the phenomenon of "outside the world".

"Well, a book." I wiped the tip of my nose and said.

"Really?" He questioned. Apparently he was aware of my little act of lying.

"I can't say, why don't you tell me what it is?" I asked.

At this time, Lingxin seemed very quiet about our conversation.

At this time, Professor Xia recalled:

Two years ago, in mid-July, one afternoon at the institute, I received an urgent mail.

"Professor Xia, there is now an eyebrow about the paranormal phenomenon you mentioned earlier." Assistant Xiao Wang knocked on the door and said to me when he came in.

I stopped my pen and took the file bag he handed me. The file bag was stamped with the words "outside the world" paranormal phenomenon, and it was also stamped with the seal of the General Administration: Top Secret Files.

The moment I opened the bag, it was difficult to calm my inner excitement, and there has always been controversy about the "outside world".

The dense text on the file records an experiment, the famous psychologist Liang Xiaosheng dreamed back to the Tang Dynasty after many hypnotic experiments on himself.

According to his description, during that time, he experienced various historical events similar to those in history books, and witnessed the legend of a generation of empress Wu Zetian. However, he was soon discovered by his assistants, and the whole person had entered a state of suspended animation, with an extremely weak pulse and heartbeat. Fearing for his safety, the assistant woke him up with the help of a device.

After Liang Xiaosheng woke up, he wrote a paper on this matter and asked his assistant to mail it to our bureau and give me a reply.

I asked him to verify this matter for me before, but Liang Xiaosheng mysteriously disappeared at home a week later. According to the clues brought by the housekeeper in his house, the light in his study was on all night, and when he delivered morning tea the next day, the person was gone.

I have been investigating this matter in many ways, but he has not been heard from so far. In this way, I suspect that his disappearance is closely related to the strange phenomenon of "the outside world", he was at first a soul piercing, and finally the whole person disappeared from the world.

Later, I carefully studied some of the main points in his paper, and found that after a person is in the "outside world", he can know the past and the present and the future alone—it is a different dimensional world.

Being there only for oneself and being intimately connected to another world seems to play a complementary role.

To put it simply, when people get there, they can perceive the world that blends with it, but they can't fit into that world.

"Just like we are now?" Lingxin interrupted him.

"Yes. Although he gave me the paper with the seal of the General Administration, there was no trace of it being opened, so I have the most say in this matter. However, his paper does not mention the specific operation of entering the 'outside world'. Professor Xia regretted.

"However, it seems that the meteorite is also the space-time hub that enters the 'outer world', and it is the last thing we saw before we got here." I added.

Although I have a general understanding of the ins and outs of the matter, as well as the existence of the supernatural phenomenon of the "outside world", I sigh in my heart for this underground palace: thousands of years ago, such an amazing secret was buried here.

"yes, I didn't expect that." Professor Xia nodded and said.
