Cheng Shi took three pieces of paper to the round table area of the hall, found a random place and sat down, and began to carefully flip through the pages one by one.

"Xiaoqiao, I don't think there is anything special about the properties of these weapons, can't other advanced civilizations in the universe create them?" Cheng Shizai asked quietly after carefully reading the first piece of paper.

"Master, there is really nothing special about these weapons themselves, many civilizations in the main universe can make them," the ship model said with a slight vibration, "but the core technology of these weapons is not in the weapon itself, but on the magic core attached to it, this core can be replaced, and installing the magic core is equivalent to loading the bullet, so the weapons they deliver are all versions without the magic core installed, so naturally they look very ordinary, and the price is not expensive." ”

Cheng Shi looked carefully at the rough weapon pictures printed on the paper, and found that each weapon had an interface reserved for installing the magic core, but this interface was not emphatically marked, as if the magic core was not regarded by the seller as the main selling point of the weapon.

And when Cheng Shi turned to the third page, compared to the first two pages, the font on this page was smaller, but it was more neat, and the table on it corresponded to the number of exchange items needed to buy each weapon one by one.

And these exchange items that need to be provided by the buyer are not scarce things in Cheng Shi's opinion, and they are all single substances, but they have extremely high requirements for the purity of the substance, such as 100% purity water, 100% purity silicon, 100% purity iron, etc.

Obviously, these highly pure substances can make a lot of things, so it is difficult to speculate on what the seller wants to do with these things.

"Xiaoqiao, is the coordinate you got in this hall?" Cheng Shi asked puzzled.

"The signal disappeared inside this spire, and the ship estimated that after the container entered the secret space here, the positioning signal was blocked, so the location information it recorded was incomplete, and the broken part in the middle should be the time of unloading." The information bridge said analytically.

Cheng Shi rubbed his head: "Then what now?" I'm not really going to be an arms dealer, am I? ”

"The ship suggested that the master let the birds go around the independent huts, and that she should have good ears, so that she could help listen to what others were talking about, so that the master could know what to do."

Cheng Shi sighed silently, he didn't expect that the owl girl's instinctive talent could one day be used as a creature to steal. Although he didn't want to do this, he didn't have any other way to advance the investigation of the matter for the time being.

To prevent theft by others. Listen, Cheng Shi specially asked the information bridge to establish a battlefield communication channel, so there was a very strange scene in the conversation between the two.

Most of the time, Cheng Shi was talking, but he didn't open his mouth, while Yang Yang watched Cheng Shi make all kinds of complicated expression changes, such as nodding, surprised, worried, etc., of course, the owl girl would occasionally interject a few words.

Under Cheng Shi's arrangement, Yang Yang walked to the innermost row of rooms in the hall with some worry, in order not to arouse the suspicion of the staff in the hall, Yang Yang pretended to find someone to check the house number of each room one by one.

"Ma'am, this is our key account area, and there are secret meetings in it, do you have anything to do?" A white-robed staff member walked up to Yang Yang and asked softly with a serious expression.

Yang Yang slowly turned to look at the white-robed little brother, and found that he was the person who had just sent information to Cheng Shi, so he smiled calmly: "

I'm looking for someone, but my eyes aren't very good, so I have to get closer to see the house number. ”

"Then tell me what is the house number you are looking for? I'll help you find it. The white-robed little brother said politely.

In fact, when the owl girl was near the round table just now, she had already seen all the house numbers clearly, but when the white-robed little brother suddenly asked like this, she was a little stunned for a while, so she was stunned for a moment: "It seems to be No. 34, I can't remember it clearly." ”

"Are you sure it's room 34?" The white-robed little brother asked with some confusion.

Yang Yang nodded, but then shook her head again, she just said it casually, the purpose was to try to say the room number back as much as possible, so that she could walk forward a little more: "I only remember that the room number starts with three, can you take me there?" ”

The white-robed little brother sighed speechlessly: "There are only 33 rooms in total, you better go back and ask for the room number before coming over." ”

"I remember, it's room 33." Yang Yang suddenly said affirmatively.

The white-robed little brother looked surprised: "Are you really sure this time?" If there are guests in the room, I can't just open the door of the room. ”

Yang Yang nodded very sincerely.

The white-robed little brother looked at Yang Yang again in surprise, and then said, "Then you can come with me." ”

Yang Yang listened to the sound in the room she passed by while walking, and she deliberately slowed down, but fortunately, the white-robed brother didn't urge her.

The two of them arrived at the door of room 33 in a short time.

Yang Yang naturally knew that if he knocked on the door of this room, the matter would be revealed immediately, so he hurriedly said: "I'm sorry, I still have to go back to confirm the room number, sorry, I'm sorry to disturb." With that, he ran to the door of the hall.

The white-robed little brother saw the back of Yang Yang leaving in a hurry, he was stunned in place, he just felt that the other party was very strange, but he didn't know what was going on.

Cheng Shi and Yang Yang said in advance that they were plagiarized. The listening strategy is to get her done plagiarism. After listening, don't go back to the round table area, just go out and find a quiet place to report the plagiarism. Listen to the results.

"Landlord, I only heard some staccato voices in the room, and the most people in there said was the energy level of the weapon, and one person said that level nine was the highest level...... Others say that the spaceship is exchanged for something...... I also heard the name of a person called 'Karel' repeatedly. Yang Yang said hurriedly, for fear that he would forget it for a while.

The mystery of the elf elder Karel has also been hanging in Cheng Shi's mind, but this time he came to find the entrance to the underground laboratory of Crystal City, and not to mention the small space in that laboratory, the main thing should have been that great changes have taken place there, so Cheng Shi naturally couldn't let the information bridge directly teleport in, which is also the reason why they came to Crystal City again, and Cheng Shi never mentioned Karel.

When Cheng Shi heard Yang Yang say the name "Karel", suddenly, he felt that all the incredible technologies that were happening in the Crystal City should be related to this elven elder who had been sleeping for thousands of years.

"Yangyang, good job, don't come in, I'll let Barbara and the three of them go out with you." Cheng Shi was in the communication channel and said comfortingly.

Yang Yang nodded vigorously and didn't speak, but Cheng Shi couldn't see her body language.

"Barbara, you take North and Kayla out to meet Yangyang, and go shopping around casually, but don't go far, I'll go talk to them with the big one first." Cheng Shi looked at Barbara with a smile and said silently in the communication channel

Road.

Barbara nodded, and left the hall with the little mermaid and the vampire sister.

"Hello, can we talk?" Cheng Shi got up and came to the white-robed little brother and asked.

The white-robed little brother glanced at Cheng Shi in surprise, and nodded with some disdain: "You say? ”

"The products on these pieces of paper you gave me are too ordinary," Cheng Shi pretended to be very sophisticated, "What I want is the magic core, who should I talk to about this?" ”

The white-robed little brother looked at Cheng Shi in even more surprise when he heard the sound, his eyes were like looking at a brain-dead alien.

In fact, people who come here to buy weapons will not look at the weapon leaflets issued by the staff at all after coming in, and will usually directly talk about some details of the magic energy core. And after Cheng Shi received the flyer from the white-robed brother, he also sat in the waiting area and studied it carefully, which couldn't help but surprise the white-robed brother, knowing that the people sitting in the waiting area were basically locals who came to interview magicians.

"Are you really here to buy weapons?" The white-robed little brother was stunned for a moment and asked.

Cheng Shi pretended to shrug his shoulders very easily, and then said in a somewhat awesome tone: "That's not nonsense, otherwise what are you doing all the way here?" I want a ninth-level magic energy core, can I talk to Karel directly? ”

When the white-robed little brother heard Cheng Shi easily say Karel, he immediately became a little intimidated: "The ninth-level magic energy core is the product that Elder Karel is most proud of, even if you only buy one, you can communicate with him face-to-face, wait a minute, I will contact him." ”

Cheng Shi immediately secretly rejoiced in his heart when he heard this, he didn't expect that the proper pretense would be so good.

After a while, the white-robed little brother came to Cheng Shi's side again.

"Elder Karel agreed to interview you, but I have the impression that there were more than two of you when you first arrived, right?" The white-robed little brother said with a polite smile.

Cheng Shi smiled, thinking that Yang Yang's strange behavior just now might not be easy to explain, so he said: "They are going to do other things, and the two of us can make all the decisions in business." ”

The white-robed little brother showed a sad face: "I'm sorry, when I just communicated with the elders, I said that there were six people in your group, I don't know if I remembered wrong?" ”

Cheng Shi pondered that Yang Yang hadn't caused any trouble before, if the other party wanted to ask, at most he said that he had just gone to the toilet, Yang Yang couldn't find himself for a while, and her brain was not good, so she rushed to the doctor.

"Oh, since you've said so, then I won't embarrass you, they should be nearby, I'll go out and call them back now." Cheng Shi said sincerely and easily.

When the white-robed little brother heard this, he immediately nodded and bowed down to express his gratitude and understanding.

Cheng Shi took Oldman to the square outside the crystal spire, and after the information bridge confirmed that the battlefield communication channel could still be fully covered, he directly broadcast in the communication channel.

After a while, Barbara took the three of them to the square to meet Cheng Shi and the others.

After Cheng Shi briefly explained the situation to everyone, Yang Yang immediately questioned it, but Cheng Shi asked her to pretend to be dumb at that time, and everything was explained by him, and the owl girl thought that there was an omnipotent team leader, so she didn't say anything.

After a brief discussion, the group returned to the hall on the first floor of the spire.

When Yang Yang saw the white-robed little brother again, he didn't dare to look at him at all, and kept silent and lowered his head, but who would have thought that after the white-robed little brother saw the six people gathered, he directly led them into room 15 in the hall.
