Huo Chi carefully checked the metal card in his hand, this thick card was silver and white as a whole, and it should be the same as the material of the unknown metal commonly found in the ruins, but there was no text on the surface of this card, and Huo Chi did not know what its function was.

What makes Huo Chi more concerned is that there are shallow reliefs on both sides of this card, and the relief on one side of Huo Chi feels a little familiar, it is a triangle that is divided into several small pieces inside, and in the center of the triangle, an X is drawn by the carver.

"Qingqing, look at this pattern, is it familiar?" Huo Chi showed one side of the card to Su Qingqing.

"It's familiar... Oh! I remember, when we were looking for my sister in Huaxia before, we had seen a similar pattern in a house that was about to collapse. Su Qingqing thought about it after looking at it a few times.

"And when we were under house arrest by the Demon Conservation Society, they also had this pyramid in their pamphlet. Huo Chi said this and thought for a moment and said: "These three figures are similar, and they should depict the same thing. ”

"You have actually been under house arrest by the Demon Protection Society?" The white fox heard Huo Chi's answer and was shocked: "Isn't that place impossible to get out of if you go?"

"That's true, I almost didn't come out at that time, and even if I ran out, I paid the price. Huo Chi subconsciously touched the ribs, he was seriously injured at that time, and his ribs were almost broken, that kind of pain, I really didn't want to experience it a second time.

"You mean you've seen this pattern in the Demon Protection Society?" the white fox took the card in Huo Chi's hand and said, "Such a rough pattern... The carving is very good. ”

"Well, it's on the brochure of the Demon Protection Society, I remembered it when I saw it, but I didn't expect to see it again here. Huo Chi said: "I still care a little about the pattern on the other side of the card, although it is also very simple, but it is very similar to some kind of map, to be exact, a bit like the subway map." ”

"What is the subway?" the white fox turned the card over and found that the other side of the card had been carved by the carver with many geometric lines. The lines crisscross and seem to be a bit like a map.

"Uh... It's a train running on the ground ... Huo Chi suddenly found that there was no such thing as a subway in this world, and he was really careless just now, and he unconsciously brought things from the original world into it.

"Do you mean the kind of train that uses rails?" the white fox seemed to know about ordinary trains.

"Pretty much. Of course, Huo Chi couldn't tell him that it was a car running under the ground, but he didn't plan to continue to dwell on this issue: "In short, this side of the thing is very much like a route map." ”

"Where is the route map?" White Fox wondered: "The train has been abandoned for many years in various countries due to the fact that the tracks are often destroyed by monsters, and now most of the tracks have been stripped and re-smelted, if you want to figure out what this is, you can only find the previous route map for comparison." ”

"You may be able to find it in the military department. Su Qingqing said: "However, there are many ancient route maps in various countries, and it may take a lot of time to find out the source of this route map. The question is, is this really a road map?"

Yes, is this really a route map? Huo Chi used to have developed rail transit in the city, so when I saw such a line map, I had a preconceived idea that this was a subway line map, but this line composition pattern may really have other explanations.

"When we have the opportunity, we will go to the computer of the military department to check, and now I can't guess what's going on here. Huo Chi took the card back and looked at the simple pyramid again, feeling that there must be some kind of connection between the patterns on the front and back of the card, but he didn't have any more clues now, and he couldn't guess what the connection was for a while.

"By the way, Abu, do you have a similar pattern in your database?" Huo Chi remembered Abu.

"Nope. Abu said: "Yes, I don't want to spend energy on checking." ”

"Poof, Abu, why did you refuse so quickly?

“。。。。。。 Abu fell silent, it obviously didn't want to answer the question at all, but Abu's silence made Huo Chi understand that the pattern on this card was indeed related to Abu's fellow countryman.

Abu is very taboo about that fellow who doesn't know what, as long as it involves that fellow, it will pretend to be stupid and stunned.

"Since we can't figure out what's going on, let's continue on our way. The white fox said: "Huo Chi, you put away that card, and when we go out, we will find out what's going on." ”

Northland White Eagle Excavation Team Dormitory Area Villa

"You checked all the places and didn't find Huo Chi and them?" Captain Su's eyes widened angrily, he couldn't believe that the White Eagle people, who had an absolute advantage in the Northland, couldn't find a few expedition members.

"Not really, don't worry. The blonde white-eyed man with a smile on his face was smiling: "We immediately sealed the border after learning about you, and the border did find some clues in the early hours of the morning, and they are still searching." ”

"It's been six or seven hours, and they're definitely out of the Northlands, you! Captain Su suddenly felt that the White Eagle Man was too unreliable, and he stood up and walked back and forth in the room, seemingly unable to calm down at all.

"Ahem, Captain Su, why are these expedition members so important to you?" The White Eagle Man also stood up, and he slowly followed behind Captain Su, as if waiting for his answer.

"Because there is a very important person in it, this person is very important to me, and he is also a shortcut to achieve your goals. Captain Su slowly walked to the foyer, his gaze casually sweeping to the ground.

"Is it a shortcut to the goal?" the man said, "With him, we can take full control of the subcontinent?"

"Hehe, what is the subcontinent, with him, the main continent can also be taken. Captain Su's face changed suddenly when he said: "Did you come to clean up again when I was asleep?"

"Nope. The man noticed that the scar on Captain Su's face was distorted, and he knew that this guy from the White Eagle Laboratory should be suspicious of something.

"No?" Captain Su's face sank: "You go back first, later, I will go to the excavation team headquarters to report the situation this time, I hope you can catch Huo Chi and them." ”

"Hmph, are there any people in the Northland that we can't catch? Soon the search will be complete, and when the time comes, we will know where they are hiding. ”

"You guys have to focus on the search over there, I'm worried that those guys might hide the expedition members. Captain Su opened the door of the villa and made a gesture of please.

The White Eagle man shrugged his shoulders and walked out of the villa quickly, the two of them glancing at each other, but both of them looked contemptuous.
