After hearing the sound of footsteps leaving from outside the door, judging that Shi Yuan had left, Hua Yuye refocused all his thoughts on the mystery that was about to be uncovered in front of him, this is the pressure that has been in Hua Yuye's heart since that night, although Hua Yuye still accompanies her sister Hua Yuyue and her fiancée Ouyang Yaxin in the past few days of the 'Midsummer Festival', and seems to be having a good time, everything is the same as usual, Hua Yuye is still the original Hua Yuye, but who can know how Hua Yuye really feels.

After Shi Yuan's interruption, Hua Yuye was no longer a little enchanted at the beginning, but the feeling in his heart would not diminish in the slightest, and he turned his head to look at the four 'maps' on the table, "Finally, everything will be over, let me see what my father left behind" After taking a deep breath, Hua Yuye put the four 'maps' together.

At this moment, the mystery is about to be revealed.

On the front of the map, there are four 'maps' that can be put together into a complete map, but it seems that this is just a map, and there are no marks or instructions on the map, and from the border, it can be confirmed that this is a complete map made up of all the fragments of the 'map', because each ' There are letters on both sides of the map, and the four are just enough to form a border composed of letters, the two letters on the left are uppercase, and the two letters on the right are lowercase, and if you look closely, you will find that there is a small dot next to the letters, as if the map is surrounded in the middle, which is why Hua Yuye regards it as a border and determines that this is a complete map and there will be no other 'maps'.

As for the back of the map, the four 'maps' are written on the backs: 'l' and '8°', 'e' and 'w', 'i' and 'n', 'n' and '55°', and the letters and numbers present on the four 'map' fragments show that the positions are all one-to-one, four horizontal and two vertical, the first line: 'i' and 'n', the second line: 'n' and '55°', the third line: 'e' and 'l', and the fourth line: 'w' and '8°'.

Just from the front, the map without markings and descriptions is just a map, which has no effect on Hua Yuye, and the depiction range of this map in front of him is not small but not large enough to judge the specific location from the world map or regional map, but if you are lucky, it is difficult to say, or for some people who can remember the world map and people who are very familiar with the location depicted on this map, it is another situation, but for Hua Yuye, there is no impression of the location on the map. But in terms of the situation that Hua Yuye is facing now, even if the geographical location of the map on the world map is determined, it is the same as the role of the map in front of him, and it is impossible to determine where the specific location is. If Hua Yuye was lucky enough to find the corresponding place when he only got three 'maps', maybe Hua Yuye would 'think' that it was useful, thinking that he had found some clues, or 'thinking' that there might be marks on the fourth 'map', so that the range was also reduced a lot, but from the current situation, the above assumptions were useless at all, then the letters and numbers on the back of the map must have decisive use, and Hua Yuye needed to find out what the use was.

Hua Yuye noticed that the symbol of '°' on the back of the map was clearly marked in the upper right corner of the number, and it was difficult not to see it, because it was very clear that it was there, and the first thought that flashed in Hua Yuye's mind after seeing the symbol '°' was 'angle', 'Since it represents the angle symbol, the degree represented by the number has a role' Hua Yuye looked at the map in front of him, and the position letters corresponding to the numbers on the other two 'maps' were 'w' and 'n', Hua Yuye immediately judged that this was 'west' and '' North', the puzzle is sometimes like a mess of threads, when you find out where the thread is, it's easy to sort out the thread, of course, the premise is that the thread can't be knotted, otherwise it will be very troublesome, this is a bit like 'escape room' This kind of game, after finding out all the 'maps' and 'letters', the next thing is how to use these step by step.

"This should be the meaning of latitude and longitude" Hua Yuye made a judgment like this, as for the reason is very simple, because this thing is so simple, at this moment, Hua Yuye's words next to him will definitely complain about him, as for whether it is the correct answer, only God knows, and Hua Yuye has no correct answer in his hand.

'Since the numbers and letters correspond to the combination, then the other four letters corresponding to the above can also be combined in pairs' Hua Yuye continued to look for the answer along his own thinking, but found that the information obtained by the combination of two and two was completely not the same as the horse's mouth, but when he looked at these four letters together, he had a flash of inspiration, which is like an idiom split into four separate words, so the first time you see these four words, you can form an idiom in the brain, because the brain is very familiar with the frequent use of this word, and Hua Yuye at this time is the same, the first time Hua Yuye saw the four letters, Hua Yuye thought of the meaning in the brain'line'.

After judging the meaning of the letters and numbers on the back of the map, Hua Yuye tried to find other ways to explain, but in the end they were denied by themselves, or affected by preconceived ideas, in the heart, Hua Yuye was convinced of his judgment after drawing conclusions, so the brain automatically blocked the generation of other possibilities, flipped the map back to the front of the map, and the information on the back was written on the white paper on the side by Hua Yuye, which is a good habit for Hua Yuye, always prepare some blank paper on the table, and always write some of his thoughts on it, and then you can sort it out。

Now the information that Hua Yuye obtains is 'line', 'latitude and longitude' and 'map'.

The function of latitude and longitude is very simple, if you just rely on this small map range to confirm the location of the place on the map that exists in this world, it is impossible for Hua Yuye, and there are no landmark buildings or landmarks on the map, but the existence of latitude and longitude can determine the location relatively accurately.

"So what does the 'line' mean' Hua Yuye was a little incomprehensible, looking at the front of the map, 'longitude and latitude' thought of doing it, Hua Yuye found the world map for comparison, and quickly determined the location of this map on the world map, although it can't be completely overlapped, but it will not deviate too much, at least from the map,' It seems that the range is not small' according to the latitude and longitude marked on the back of the map Hua Yuye determined the location of the intersection of the two lines on the map, although it seems that this place does not have any particularity at all, but Hua Yuye's mood at the moment is extremely excited, excited to jump up, assuming to imagine the mood when winning the jackpot xxx million, although this is a little different, but Hua Yuye's mood at the moment is still somewhat similar, and at this time Hua Yuye very much wants to share this mood with others.

"It's all going to be over" Hua Yuye suppressed his excitement for a while, raised his head and looked at the time, and found that it was almost evening when he arrived at the school, from the morning to the school, and then various activities, after lunch, to the afternoon when he was called to the principal's office to get this last clue, and when he returned home, it had been a few hours unconsciously, and when he was fully engaged, time slipped away quietly.

'Knock knock' sounded at the door, "Young Master Yuye, it's time to have dinner" Shi Yuan's voice came from outside the door.

Hua Yuye only notified Ouyang Yaxin when she left the school and asked her to ask for a leave of absence for herself, nor did she explain the situation to her in detail, and she also did not inform her sister Hua Yuyue, so Hua Yuyue still doesn't know the reason why Hua Yuye left the school, and Ouyang Yaxin just thinks that Hua Yuye has left beforehand, for them, it doesn't matter whether the school courses go or not, even if they don't go to class for a semester, as long as the credits are enough, they can go to school as usual, which is why Hua Yuyue and Ouyang Yaxin have already finished school but didn't come to ask Hua Yuye, Hua Yuyue has been home for a while, Fluttershy also learns that Hua Yuye has arrived home.
