When the group entered the small room 15, the layout was much simpler than they expected, there was only a bench in the room, not even a table, and the walls on all sides were empty, and there was a magic crystal lamp hanging on the roof, which looked like an enlarged version of the lamp on the ceiling in the hall outside, but the difference was that the lamp was obviously hung up, and it was red and white, exuding a somewhat yellowish light.

"Please wait here, Master Karel is talking to the others right now, and will be here in a moment." The white-robed little brother stood at the door and said in a normal tone.

Cheng Shi nodded, indicating that he could wait here, and then the white-robed little brother gently closed the sliding door to enter the room.

After waiting for about five minutes on the benches in the room, a figure suddenly appeared on the milky white wall in front of them, and the figure gradually changed from blurry to clear.

"Is that you?" Karel, who was dressed in blue overalls, showed a look of surprise when he saw Cheng Shi and the others.

Cheng Shi quickly looked up and down, left and right when he heard the sound, and found that the magic guide video call technology in this room was quite interesting, there was no display screen, no projector, and no camera, the images on the wall seemed to appear out of thin air, and the other party could obviously see the people in the room.

Although Cheng Shi was looking forward to seeing Karel again, in order to better communicate with him, when he saw Karel's somewhat surprised expression, he deliberately behaved very calmly: "Long time no see, you look much better." ”

"Old man, you don't look like you woke up thousands of years ago." Yang Yang couldn't help but be surprised when he saw Karel with a full face.

Karel smiled slightly awkwardly: "As you think, I'm healthy now, and I'm already in charge of the lab, since we're old friends, let's meet and talk." ”

Cheng Shi hurriedly nodded: "Okay, you have changed so much here, I have a lot of questions I want to ask you, is it convenient for you now?" ”

Karel bowed slightly: "Yes, you can come here, there is a magic elevator in room 1, I will wait for you in the underground laboratory." ”

After Cheng Shi walked out of room 15 with a few people, he briefly told the white-robed brother outside about the communication with Karel, and he didn't ask anything, and walked directly to room 1 with a few people.

The only difference between the decoration of room 1 and room 15 is that the floor is black, and it can be vaguely seen that the floor is separated from the four walls.

Once the group had taken their seats on the benches in the room, the floor began to descend silently, and after about two minutes, they reached the finish line.

With a sliding door with various complex runes suspended on it slowly opened, everyone saw a woman with a European face standing at the door of the elevator, she was wearing blue overalls, blonde hair and blue eyes, she was not a native of Tikonia at first glance, and at this moment she was waving to Cheng Shi and the others.

"Aven, you're not dead either?" Kayla saw the acquaintance in front of her, and she couldn't hold back for a while, and directly called out a name that no one had ever heard of.

"Are you talking to me?" The woman, whom Kayla calls "Aven," pointed at herself in surprise.

Cheng Shi saw that the laboratory staff who came to greet them obviously didn't know Kayla, so he hurriedly glanced at the vampire girl.

"I'm sorry, you look alike to a friend of mine, I recognized the wrong person." Kayla hurriedly explained.

"It's okay, my name is Susan, the elder is already waiting for you in the living room, please come with me." The woman who claimed to be named "Susan" motioned for Cheng Shi and the others to go with her after speaking.

When Cheng Shi and his party came to the laboratory corridor, except for the floor, there were complex magic runes suspended in the corridor, and even some rune symbols occasionally crossed in the air, and this underground laboratory was obviously expanded on a large scale, standing in the corridor, it was almost impossible to see the end.

The crowd walked for a long time under Susan's leadership, and finally came to the parlor she had spoken.

It was a room, roughly fan-shaped, spacious inside, with a large round table in the middle, filled with all kinds of fruit and fruit snacks, about a dozen chairs around the round table, a few magic crystal lamps of different shapes but no aesthetics hung on the walls on all sides, and a black and neatly arranged pipe on the roof, but there was no other excessive decoration.

If it weren't for Susan saying that this was a meeting room, Cheng Shi would have imagined that someone would design the meeting room like this, because the gloomy atmosphere exuded from the whole room was very unsuitable for all kinds of business negotiations, but now he could only understand it as a cultural difference from different planets.

Karel stood quietly in the corner of the room, and when he saw Cheng Shi and his party enter the room, he greeted him and waved Susan to leave.

"I know you must have a lot of questions to ask, and I can talk to you here today." Karel said with a smile that was not too much to ponder.

"Okay, this time we came here to learn more about your situation here, to see if there is anything we can help with, before I said that I wanted to buy magic cores, just to see you, you should be able to understand, right?" Cheng Shi said frankly.

Karel smiled and nodded: "It's nothing, I know you'll come sooner or later," he waved his hand and motioned for a few people to sit down, "The meeting room is temporarily prepared, but the fruits are fresh, you can eat whatever you want, you're welcome." ”

The three underage girls in Cheng Shi's team have long been salivating for all kinds of alien fruits on the round table, but they still know the most basic rules, and they can only swallow saliva in their stomachs before they receive the leader's order to eat.

After the group sat down, Cheng Shi told everyone in the communication channel that they could eat the fruit on the table, but reminded them to pay attention to their appearance.

"Can you tell me what's going on with the aliens working in your lab right now?" This was the first question Cheng Shi wanted to ask, because he had followed the footsteps of the aliens on the earth this time, and he had just seen several staff members who looked like earthlings in the corridor of the laboratory.

Karel was not surprised by Cheng Shi's question, only to see him frown slightly: "Those people you see are not aliens, although they look a little different from us now, they are still the descendants of our people." About 5,000 years ago, our universe has undergone great changes, there are many spaceships from other worlds in space, at first we were reluctant to contact these people with unknown purposes, but they were very interested in some of our magic technology, so they forcibly landed on the surface of this planet, when we found that our magic energy air defense weapons did not work on the shields of their spaceships, we could only submit to them and try to communicate with them, and then they were sent

Some followed their spaceship to their universe. ”

After listening to Karel's more brief description, Cheng Shi thought that it was not particularly unexpected, but how did the aliens come to the earth, and still did not get an answer, you must know that on the earth more than 5,000 years ago, human civilization may have just had a prototype, and it is impossible for someone to drive a spaceship across the universe to bring people over for tourism.

"Outside of this universe of yours, there are indeed other universes, which we call the main universe, and this universe of yours has had problems since its birth, which is why it is what it is today," Cheng Shi said in a language that Karel could easily understand, "Why are you building such a huge underground world here?" Is it because the surface ecology is not suitable for survival? ”

Karel sighed: "Planet Parro is far away from here, we can come here and survive here, it is enough to show that we have mastered ultra-high astronautical capabilities, but as you said, there is a fundamental problem in our universe, but we didn't know this situation at the beginning, we went to many galaxies in this universe and found many planets that should have evolved higher life, but they either did not evolve life, or did not evolve higher life, or have become extinct, It makes us desperate. ”

Karel paused as he spoke, and when he saw Cheng Shi staring at him intently and listening to him very carefully, he continued: "When we first discovered this planet, there were only some primitive plants and lower animals on it, and the planet's ecology was already very fragile, but it was still dying, but its underground was rich in water resources, and we were forced to settle on this planet in the end. We have gone through great pains to build the Crystal City on the surface of this planet, and use magic technology to transform the surface ecology of the planet. But we soon found out here that something similar to Parro's was changing, and we were desperate at the time, but in order to live longer, we did everything we could to build the current underworld, and when we did this, we didn't cheer, because we knew it was just a delaying tactic. It wasn't until we came into contact with people from other universes that we realized that there really were heavens beyond the heavens, so we industrialized the magical energy technology they were interested in in exchange for their technology. ”

Cheng Shi saw the complicated expression on Karel's face change, and after being silent for a long time, he asked again, "Then what are you sending people to the main universe for?" Is it to find a more stable ecological planet? And how did you get in touch with the people who were sent out? ”

"Yes, for us, survival is the number one priority," Karel first confirmed Cheng Shi's speculation, and then said, "In exchange, we offered to let some of us follow their spaceship to visit and study in their universe, but none of these people will come back alive, and the explanation they give is that these people will suffer the same convulsions when they arrive in their universe and will die soon, we didn't believe it at first, but they showed us the holograms they recorded, We didn't understand it, but we couldn't help it. At that time, we were just thinking of sending some people to their universe to see the field, so we didn't think about connecting them across the universe. ”

Cheng Shi nodded, agreeing with the logic of Karel's statement, and at the same time sympathizing with the elves' plight.

But I don't know why, Cheng Shi always felt that the elf elder in front of him today was surprisingly cooperative, not only asking what to say, but also saying it in as much detail as possible, which couldn't help but surprise him a little.
