Chu Ling dragged his suitcase and walked behind Luo Xi for a while, and then came to a cave.

He looked at the cave with some surprise and said, "Isn't it?"

"Yes, the cave you chased to the door that night and didn't go in. Luo Xi said and looked at him with an inexplicable smile, "Later, I went in to check and didn't see any ghosts." The train did not start, and the train could not enter the original boundary without starting. But it just disappeared inside, don't you think it's weird?"

Although he felt that Luo Xi had something to say, Chu Ling didn't bother to care about it, he opened his mouth and asked, "Inside this cave, is the road to the original realm?"

Luo Xi carefully examined Chu Ling a few times, and then led the way in front of him: "Come with me, you now have the qualifications to enter and exit the Origin Realm, and you can come in." ”

Chu Ling nodded, followed Jinru into the cave, the cave is a classical metal structure similar to other places, and after walking for a while, he came to an elevator, the two stepped into the elevator, the elevator went all the way down again, and Chu Ling estimated that it was at least a hundred meters or so deep.

Neither of them spoke along the way, and since Luo Xi made things clear in the hospital, there would be an awkward atmosphere when the two of them were alone.

When they stepped out of the elevator, they came to a small train station, and out of the only three platforms, only one platform was now parked with trains. And this kind of train is not big, except for the front of the locomotive on the left and right, there is only one carriage in the middle.

"Take the train to the Origin Realm?" Chu Ling asked a little strangely.

In his imagination, it's another world, and the way to travel through the world should also be very high, not to mention a fantasy teleportation magic array, but also a wormhole crossing with a sense of science and technology. Now it's just a train away, which makes him a little disappointed.

"What, how do you think you have to go to the Origin Realm?" Luo Xi asked as she looked at Chu Ling with some amusement.

"Uh. Chu Ling thought about it, but still didn't say the plots in his mind and the movie in his mind, he just complained, "You said you were going to another world, I was thinking that I might look a little taller." ”

"What's wrong with taking the train? Actually, you seem to have misunderstood something, the original realm cannot be said to be another world in the strict sense. Luo Xi took Chu Ling to a uniformed staff member and took out his own documents, after the staff scanned it, Luo Xi took out another document for him to scan, and after finishing it, he turned around and handed it to Chu Ling and said, "This will be your document from now on, be careful not to get rid of it, the money for the replacement will come out by yourself, and it is not cheap." ”

Chu Ling took the document and looked at it, there was a card in the small notebook, and there was a headshot of Chu Ling in the upper left corner of the card, and next to it was his name, ability department, ID number, and personnel rating. It doesn't give a detailed name to the ability, as it's a very private thing for the ability, and the person rating is a "D" at the end.

Chu Ling took a look at it and put it away, and followed Luo Xi

trains. The train was empty, and there was no passenger except for a waiter at the bar at the end.

After Luo Xi casually found a place to sit down, he pointed to the bar and said to Chu Ling: "If you want to drink something, go and order it yourself, and by the way, help me order a milkshake, thank you." ”

Chu Ling glanced at her a little speechlessly, then put away his luggage, walked to the bar and ordered a milkshake and a beer. For some reason, he's been relying on beer lately.

After putting the milkshake in front of Luo Xi and watching her cutely lean over to the straw and take a deep sip, Chu Ling asked, "Why do you say that the original realm is not another world?"

"What theories about space did you talk about during your training?" Luo Xi asked suddenly, playing with the small buoy floating on top of the milkshake.

Chu Ling was stunned for a moment, and then he spoke: "There is only Estan's theory of spatial energy loss, and it seems that it only talks about the first half." ”

"Well, Estein is the first person to awaken the 'super intelligence', not only did he publish a lot of classic theories in the world of ordinary people, but then the world of Jinru was also researched a lot of things. Luo Xi pointed at Chu Ling with a buoy and said, "In addition to the theory of spatial energy loss, he also published a famous theory, do you know?"

"What theory?"

"The Theory of the Density of Space in the Universe. ”

Chu Ling suddenly became a little interested, and after he took a sip of wine, he leaned forward and said, "Tell me." ”

"Liquids have densities, the liquid with high density is below, and the liquid with low density is above, and the two sides do not interfere with each other, and there is a clear distinction. Space is the same, space is originally a huge energy aggregate, they also have energy density, and the energy density in this aggregate is not all the same. These energies of different densities are all in an aggregate, but they do not interfere with each other. ”

Luo Xi took a sip of the milkshake and said: "Actually, you have a problem with the definition of the world, a world represents a law power, and a law power represents a space, but in a space, there is not necessarily only one plane. The energy of different densities in a space will produce multiple small planes in it, which belong to the same space, but do not affect each other, which is very magical. ”

"In ancient times, the Origin Realm should have been called the Immortal Realm. When we go from the earth to the original realm, we are actually going from a high-density liquid to a low-density liquid, as long as we find the right method and location, it is not difficult to cross. But what you are talking about traveling through the world, that is the law that you have to break this world, and then find another law outside the world, and then break it in, is basically impossible. ”

"The earth and the primordial realm are like liquids of different densities in a cup, they actually belong to the same space in essence, but they are layered because of the different densities. It's not too hard for us to want to go from one liquid jinru to another, but if we want to break the cup jinru another cup, it's even harder. ”

At this moment, only the radio was heard.

"The cross-border train is about to depart, and bumps on the road are normal, so please don't be nervous. ”

Chu Ling came back to his senses, only to find that there were already several people sitting around.

At this time, the train began to move slowly, Chu Ling curiously leaned to the window to watch, this was the first time that the train that crossed the plane had been done, and he had to witness this scene well.

However, he was not interested after looking at it for a while, because here is the same as in the subway, there are advertising lights on both sides, the only difference is that the advertising lights here should be the advertisements of some companies on the other side of the original world.

As the speed of the train gets faster and faster, the advertising lights have also been left behind. At this time, steel plates began to be lowered from the windows of the train, and the entire carriage was closed at once.

Chu Ling looked around, and those people all had strange expressions, obviously they had long been accustomed to it.

Seeing his puzzled look, Luo Xi smiled and explained: "To start crossing, the glass can't resist the oppressive force brought by crossing the plane, and in this process, a highly strengthened special metal is required to resist the impact and oppression of turbulence. ”

Chu Ling was a little nervous for no reason after hearing what she said, thinking in his heart what if something happened to the train on the way through?

Chu Ling asked himself this question, and Luo Xi showed a sly smile when he heard this, and said: "If something happens, then you will accept your fate, what else can you do? Are you not afraid of accidents when you take a plane or train outside? ”

Chu Ling smiled awkwardly, the first time he took this train, he would always think about such and such things in his heart, to put it bluntly, it was not practical.

At this time, Luo Xi seemed to deliberately speak: "Besides, if we have an accident on the way through, we will definitely fall into the turbulence between the two planes, this place, no one dares to search and rescue." ”

Chu Ling's face turned pale when he heard this, and he had words in his heart, God, Buddha, you bless me a lot.

And things didn't seem to be as Chu Ling wanted, and at this moment, the train slammed!

From the outside, the whole body of the train was covered with a layer of bright white substance, and in front of it was a rock wall!

At this time, a white ray suddenly shot out from the front of the car, and the ray shot on the rock wall, which actually made the rock wall ripple in a circle, and then from the very center of the ray, seven kinds of visible light mixed with red, orange, yellow, green, blue, and purple, the circle slowly expanded, revealing a deep black hole in the center.

When the train reached the end of the track, it rushed directly into the black hole.
