"There are no similar patterns on the map, have you also compared the city maps, such as railways, highways, and shipping routes?" Huo Chi was a little unwilling when he heard this.

"That's for sure, I've compared the patterns on the map, and it's really not exactly the same, not even more than 80% similar. Abu replied helplessly: "I can't help it, how can I not find it? ”

Abu couldn't find a map identical to the metal key, and Huo Chi was completely confused. This place can be said to be the most comprehensive military department on the map of the subcontinent, and the data reserve even exceeds the official reserve.

If he couldn't find the corresponding map here, Huo Chi really didn't know where else to find it. Unless you return to the headquarters of the Huaxia Expedition on the main continent and look for information there, you may be able to find more valuable clues.

However, it is impossible for them to return to the main continent now, and even if they have the return ticket given by Mr. White Fox, the snow leopard team must go to the sentry post to recover first.

Alas, it seems that this matter can't be solved for the time being, and if you want to figure out what the hell is going on, you may have to return to the main continent to continue.

Thinking of this, Huo Chi took off his gloves very regretfully, there is no need to delay time here, hurry up and buy gasoline.

"Huo Chi, don't you continue to search, is it time?" Su Qingqing found that Huo Chi had put his gloves on the table, and seemed not ready to continue.

"I still can't find it, there are too many ancient maps here, there is not enough time, and if you want to read all the maps here, it will cost too much money. Huo Chi said with some regret: "I didn't think about it well, I thought it would be easy to find." ”

"What the hell are you looking for? Could it be those patterns on the Ice City Key?" The Sugar Glider knew a thing or two about it, so she knew what Huo Chi and the others were doing after a little thought.

"Well, that's it. Huo Chi didn't intend to hide it from her, so he nodded and said, "It's a pity that there are too many maps and limited funds." It's like looking for a needle in a haystack. Moreover, among the maps that have been seen, there is no one similar to it at all, and it may be very difficult to find the map that corresponds to that figure. ”

"Looking for a needle in a haystack, that's an interesting word. After reciting two sentences of looking for a needle in a haystack, she suddenly raised her head and looked at Huo Chi and said, "Is the direction you are looking for? Could it not be a map at all?"

"It is possible ... I couldn't think of anything else, though. And with each additional possibility, the amount of information that needs to be searched doubles, so it's a real clue. "Huo Chi thinks Patassas has a point, but if it's not a map, what could it be?

"Could it be the figure in this?" said Sugar Glider, holding up the old book in his hand.

"Ancient aqueducts?" Huo Chi took a closer look and found that the book in the sugar glider's hand turned out to be an architectural book introducing ancient aqueducts, and he couldn't help but ask curiously: "Could it be that there are similar figures in the aqueduct?"

"yes, look at this, doesn't it look like it? I vaguely remember that the card was a similar pattern, right?" The sugar glider flipped the book in his hand and showed a piece of hand-drawn paper inside in front of the two of them.

"Huh?" Huo Chi narrowed his eyes, and on the yellowed old book in front of him, there was a fine drawing of the aqueduct, and the aqueduct on the drawing was criss-crossed, and it did look like the pattern on the key.

"Wouldn't it, look around and look for it, that pattern is not a map at all, but a water conveyor?" Huo Chi snatched the book and began to read it seriously.

"Maybe it's not an aqueduct, maybe it's an electrical circuit or something?"

"No, no, it's the water pipeline!" Huo Chi quickly flipped through the entire book, he didn't actually look at it carefully, but handed over the task of comparison to Abu again.

Abu acted quickly and compared the aqueduct drawings in the book one by one, and to Huo Chi's surprise, it really found a similar pattern, but a pattern with a similarity of up to 99%, in a sense, the two patterns should be the same!

"Really?" Sugar Glider was also a little surprised, she just said it casually, but she didn't expect to make her say it right by mistake?

"Really, look at this picture. Huo Chi turned around and spread the old book on the table, he took out the drawing he had rubbed out of his arms and put it on the old book.

Su Qingqing and Patassas hurriedly came over, and when they took a closer look, they all showed joy.

"I'm really right!" the Sugar Glider excited.

"Found it, finally found it, great!" Su Qingqing was sincerely happy, after all, this pattern is inextricably linked with her sister, and if she finds one of the links, she may really be able to unlock her sister's secret.

"Well, it's exactly the same, thank you, Patassas, for helping me again!" Huo Chi was genuinely grateful to the Sugar Glider, this girl was such a lucky star, without him, he and Abu would not know how long they would have to delay on the map.

It really takes no effort to break through the iron shoes and find nowhere to find them, and the answer lies in this ancient book on the aqueduct. It turned out that the pattern on the key was not a map, not a road or railway, but a water conveyor.

Huo Chi felt that when he had contact with the aqueduct in his life, that is, when he was in the world geography, the teacher briefly introduced the ancient Roman aqueduct in class, and the aqueduct in this world was much more complicated than what he saw at that time.

On this hand-drawn drawing in front of me, many aqueducts are intertwined, and when viewed from the air, these aqueducts are as complex as the original subway line, which is really magical.

"Hehe, I didn't expect it either, it just happened, it just happened. Patassas' face flushed, and he was embarrassed.

"This happens to be so useful, otherwise I don't know how long I'm going to have to look for it, and the key is that I can't find it right. Huo Chi flipped through the two pages of the old book and said, "Laconia, where is this place, why can't I find it on a modern map?"

"Because, Laconia is now gone. Su Qingqing also saw the real address of the aqueduct, and these words seemed to be too dazzling, which stabbed her eyes a little bit.

"Disappeared?" Huo Chi was puzzled, he casually took a modern map and said, "Where can it disappear? Where was it originally located? Qingqing, you tell me." ”

"It should be here. Su Qingqing rubbed her eyes, stretched out her hand and clicked on the map: "It's here, but it's gone." ”
