In the next two days, Tu Fei finally found the right direction, and there was no mistake in the direction of everyone's progress, so after two days of travel, Tu Fei led everyone to the center of the sand sea.

Along the way, everyone did not find any traces of those people of the Yang family, obviously their own people and the people of the Yang family are moving in different directions, so they did not find any traces, Chu Tianci believes that those people of the Yang family will never give up easily, after all, they have worked hard for so long, and they see that the benefits that are about to be obtained, how can they suddenly give up, although now they have successfully escaped from the hands of the Yang family, but the people of the Yang family will definitely choose to go to the center of the sand sea.

After really coming to the central area of the sand sea, Chu Tianci really understood the importance of Tu Fei's guide, in Chu Tianci's eyes, the sand was exactly the same, but in Tu Fei's eyes, it was completely different, it was precisely because of Tu Fei's existence, so Chu Tianci and his party were able to successfully avoid most of the quicksand, maybe at the beginning, Chu Tianci didn't believe that those areas of dodging belonged to the quicksand area, but after trying a few times with distrustful eyes, Chu Tianci knew that he had to admire Tu Fei, every time, the quicksand area that Tu Fei pointed out had never missed it, soAt this moment, the importance of Tu Fei is self-evident.

In this central area, everyone walked forward for a long time, and finally Tu Fei finally led everyone to a special place, according to Tu Fei, this place is actually a river, maybe it is also because of the previous sandstorm, so at this moment, it seems that there are more things that have been submerged by the desert to reappear in the world, but Chu Tianci is not good at these at all, so after careful observation, he can't make such a judgment.

After more than two days, Professor Gu's sadness has finally eased a little, although several of his students are still missing at the moment, but Professor Gu knows that it is more important that he should determine the specific location of the ruins as soon as possible, and only really let the ruins be included in ** Within the scope of protection, his task can be over, so at this moment, Professor Gu can only pack up his mood and find a way to find the ruins, after all, if he is one day late, maybe the Yang family will have one more chance, Professor Gu naturally does not want these things to fall into the hands of the Yang family.

Different from Chu Tianci, after Tu Fei made such a judgment, Professor Gu immediately went on a field investigation, and after Professor Gu's investigation, Professor Gu finally agreed with Tu Fei's conclusion, and the place where everyone was at this moment was really a riverbed.

It's just that Chu Tianci doesn't understand that everyone's goal is actually the ruins that have been revealed, and now they are looking for this riverbed, but they don't know what the intention is, and Chu Tianci still asked Professor Gu bluntly about his incomprehension.

Professor Gu had no intention of continuing to conceal it, after all, it was not only Chu Tianci who did not know the intentions of Professor Gu and Tu Fei at this moment, even Professor Gu's own students were puzzled, and they did not ponder for too long, Professor Gu directly said the final answer.

Professor Gu admitted for the first time that what he obtained in Kyoto was actually an ancient map, for this matter, Chu Tianci knew, and Chu Tianci also knew, in order to find the target faster, Professor Gu temporarily handed over the ancient map to Tu Fei to study, and it was precisely for this reason that the ancient map was retained, because of Yang Jin's betrayal, so the people of the Yang family also knew that in the hands of Professor Gu, there was something that would be helpful for this operation, after all, Professor Gu had not told anyone about this ancient map before, so even Professor Gu's students did not know the existence of this ancient map。

When the people of the Yang family searched Professor Gu's personal belongings, they did not find anything useful, because in their opinion, the items that Professor Gu got would definitely be carried with them, but they did not gain anything at this moment, and they naturally had doubts about Yang Jin's information in their hearts, or rather, what Professor Gu got from Kyoto was just a message, after all, this kind of thing Professor Gu could remember in his mind after hearing it, so when he searched his belongings, he would naturally not find anything, so later the people of the Yang family were not so imperative to get this thing, as long as Professor Gu was in his hands, then this thing will be known by the people of the Yang family sooner or later.

No one would have thought that Professor Gu would hand over this item to Tu Fei, so the ancient map was preserved, and after Tu Fei took out the ancient map at this moment, he said to the others around him: " The meaning of Tu Fei's guide is very simple, because we have such a map in our hands, so as long as we can find any of these iconic objects, if we want to know the specific location of the target location, it will be much simpler, but as we all know, most of the things have been buried in the desert to the ground, so now there is a riverbed, we should naturally pay attention to it. ”

At this moment, everyone naturally finally understood Tu Fei's plan, the destination that Professor Gu needed to go to, the only thing Tu Fei knew was that they were located in the central area of the sand sea, but where it was, Tu Fei couldn't know, if that place had been completely buried, everyone didn't even know where to go to excavate, and now it's different, a riverbed suddenly appeared here, then it is completely possible to roughly infer the specific location of the city according to the river on the ancient map, although it is still impossible to find the exact location, but this is enough to shrink a lot。

After everyone understood Tu Fei's intentions, they began to look for it on the ancient map, although there are many cities on the ancient map, but in fact, the real scope of this map is not particularly large, and, according to Tu Fei's estimate, most of the areas in this ancient map are actually in the center of the sand sea, so naturally, as long as you find the river in the center of the sand sea, and then compare it with the actual terrain, you should still have the opportunity to find the real target location.

Of course, although the river channel that appeared in the center of the sand sea is not long, it is not particularly short, so the riverbed in front of everyone at this moment, because it is only a part of its whole picture, so everyone can not determine which section of the river it belongs to according to the appearance of this riverbed, naturally, everyone can only see it as any section of this river, and then deduce the exact point of the target location according to this river.

According to the continuous inference of everyone, the final target location is determined in a narrow area, and the next goal of everyone is to find any clues through this narrow area, so that everyone can finally find the real destination.

Because of the specific location, after checking the area deduced by everyone, Chu Tianci frowned slightly, for finding the target location, Chu Tianci asked himself if he had no talent in this area, and in the matter of finding the target location, Chu Tianci generally did not express his opinion, but at this moment, when everyone was ready to really leave, Chu Tianci had to say:" Professor Gu, according to the area you deduced, if you want to complete the search, I am afraid it will definitely not be able to be completed in a short time, as Tu Fei expected before, it was originally a day's journey, and it took us two days to reach the central area of the Sand Sea, and now we have to rely on our own legs to move forward, so in this way, there will be more time wasted, I am afraid that the fresh water we have left is not enough to support us to stay here for a long time. ”

Chu Tianci finally said his worries, after all, in the desert, if there is no fresh water, he will soon die in this desert, everyone knows that the most important thing in the desert is fresh water resources, after all, it is impossible for everyone to carry too many fresh water resources, and the consumption in the desert is also very huge, so naturally it is impossible to support everyone for too long, but now Professor Gu has to search a large area, if everyone can't leave the desert before the fresh water is exhausted, it is very dangerous for everyone。

For Chu Tianci's reminder, Professor Gu hadn't said anything yet, but Tu Fei spoke first, "Captain Chu doesn't need to worry, although we are in the desert now, it is not completely impossible to find a water source, I remember that there is a well in the center of the Sand Sea, as long as we go to that place, we can replenish the freshwater resources we lost before." ”

This kind of thing, Chu Tianci is the first time to hear of it, originally Chu Tianci felt that there was no water source in the desert, but now he found that his knowledge of the desert was a little lacking, it turned out that in this desert, there would be such an existence as a well, so with a suspicious look, Chu Tianci looked at Professor Gu on the side.

Professor Gu came to the desert earlier than Chu Tianci, and before he really entered the desert, he also learned some common sense from some local people, so he naturally knew more than Chu Tianci, so he explained to Chu Tianci.

This desert was hundreds of years ago, but it was not necessarily a desert, at that time, there were also cities here, and in order to survive, there would naturally be some wells, maybe sometimes those wells were built, and the location chosen was more lucky, so that they could avoid being flooded by the desert, and in this way, the wells were preserved.

Of course, there is also a water source in the desert, and where there are many quicksand areas, the water source is more abundant, the reason why you can't see water in the desert is just because all the water in the desert is groundwater, and it is precisely because of the existence of groundwater that the quicksand can be generated.
