Hearing Gao Chao's order, Da Liu and Xiao Liu worked hard, grabbed their backpacks as fast as they could, and jumped directly into the water with Gao Chao.

The surface of the water has begun to change, not only the waves are rising suddenly, but even the originally warm wind around seems to have become much stronger immediately, and the three of them are trying to swim towards the center of the sea, because according to Gao Chao's idea, if this sea really starts to move, only the center of this water area is the safest.

Gao Chao swam at the front, he really didn't expect that this sea that didn't seem to be big, but the water was very deep, he had tried to swim downstream, wanting to see how deep the water was, and he also had a bottom in his heart, but he tried to swim a distance downstream, but found that this place was much deeper than he imagined, and finally both strength and strength were a little inadequate, so he quickly swam to the surface.

At this time, Da Liu and Xiao Liu had already swam up, and when they saw Gao Chao emerging from the bottom of the water, they asked him very worriedly if he was in trouble, Gao Chao waved his hand and said that it was okay, although he still had some pain in his legs, it did not affect swimming in the sea.

At this moment, suddenly a gust of wind blew on the water, blowing huge waves on the water, Gao Chao and the three of them were caught off guard, they were all filmed miserable, Gao Chao shouted loudly in the gap: "Quick, hold your breath." ”

Da Liu and Xiao Liu both heard Gao Chao's words, and both of them immediately took a deep breath with Gao Chao, and quickly dived underwater before the next big wave hit.

Not to mention, the wind is strong on the water, but at a distance of about two meters underwater, it is already relatively calm.

Da Liu turned on the water flashlight, and suddenly grabbed Gao Chao, signaling him to look at the bottom of the water, everyone took a look, good guy, only to find that under the action of the light, the bottom of the water is like a constantly tumbling water surface, which makes people look at it with a fantasy feeling.

In fact, Gao Chao has already understood that the bottom of the water that seems to be tumbling is not actually something underwater, but that the bottom is constantly moving, of course, this is only a relative movement, thinking that the bottom of the water is just a sand dune, and what is really moving is actually the sea where they are located.

I saw that the sand dunes at the bottom of the water kept receding to one side, sometimes high and sometimes low, sometimes slow and sometimes urgent, which is also the reason for the huge waves over the whole sea.

Gao Chao looked at Da Liu and Xiao Liu next to him underwater, the three of them were a little overwhelmed, if they continued at this speed, they really didn't know where they would be taken by this sea, if they didn't do it, they would never be able to find it back.

Just as the three of them were about to float up to breathe, Gao Chao noticed that the water surface had been much quieter, and when he looked down, the sand dunes under the water were also slowly stopping, that is, the sea should have temporarily stopped moving.

So Gao Chao made a gesture, and the three of them immediately swam quickly to the surface.

Emerging from the water, all three of them gasped for air, and the same scorching sun shone on their heads, immediately making them feel a burst of warmth, which was much more comfortable than underwater.

Da Liu looked back and forth in a rough manner, and then said to Gao Chao: "Old Gao, this place ...... This place is really different from what it was before. ”

Xiaoyanagi also said: "Yes, where are we running now?" ”

Gao Chao waved his hand and said, "Go ashore first, quickly." ”

The three of them swam to the nearest shore and soon climbed onto the sand, Da Liu sat on the ground and wanted to rest, but Gao Chao immediately asked Xiao Yanagi to take out their special locator and let him find where they were now.

Xiao Liu used the locator to locate it, and then quickly showed it to Gao Chao, Da Liu also came up at this time, and the three of them formed a circle, all staring at the screen on the locator.

Gao Chao suddenly nodded and said, "You see, where we are now is the north of where we were before, and judging from the instrument, we have moved a distance of about five kilometers. ”

"Five kilometers?" Da Liu also carefully checked the locator in Gao Chao's hand, and then said in surprise: "My mother, it only took a few minutes for us to go out five kilometers?" ”

Five kilometers in the desert is not a joke, if it is walking, it needs to keep climbing over various sand mountains, that is, it has to continue to rise and fall, so the distance of five kilometers is equivalent to more than ten kilometers, which does not take into account the weather conditions and other factors, so it is very difficult to cross five kilometers in the desert.

Gao Chao was not surprised by this, but he immediately took the locator and climbed a sand mountain next to him, after all, his legs and feet were inconvenient, Xiao Liu and Da Liu hurriedly went up to help, and the three of them climbed the sand mountain, all tired enough.

The sun was probably at noon, and it was extremely uncomfortable to shine on them.

Gao Chao didn't care about this, but immediately looked in the direction where they were before, five kilometers away, looking at the sand mountain, he could even see some clues at a glance.

Da Liu and Xiao Liu were both waiting for the results of their superb observations, and no one dared to speak.

After a long time, Gao Chao suddenly said: "Look, the area we came from here, can you see a winding ridge next to it?" ”

Da Liu was stunned for a moment, and quickly squinted his eyes to look into the distance, Xiao Liu's eyes seemed to be much better, and he nodded and said, "Don't say, Lao Gao, there is indeed a winding ridge that curves like a snake from over there." ”

"It's really ......" Da Liu also said suddenly: "There really is, it really looks like a snake, but this ridge is all sand mountains, could it be caused by strong winds?" ”

Gao Chao shook his head, didn't speak, and kicked the sand under his feet twice, and then said: "Look, how can there be so much sand on this sandy ground?" ”

Only then did Da Liu and Xiao Yanagi notice that what Gao Chao said was that although they were on the sand mountains, and there seemed to be yellow sand all around, there was a very hard and thick shell on the surface of these sand mountains, and even if they kicked it with their feet, they couldn't kick the sand to pieces.

Xiao Liu nodded and said, "That old Gao, do you mean that these sand mountains are fixed?" Won't move? ”

Gao Chao nodded and said: "Most of the sand mountains in the desert can move, but this area is different, in addition to the hard shell in the sand mountains, there are also those moving Haizi, I think, this has a lot to do with these sand mountains." ”

Da Liu was stunned and said: "Lao Hu, then tell me, this Haizi can move, what does it have to do with Shashan?" ”

Gao Chao said: "There is a saying in Feng Shui, when the wind meets, the qi is dispersed, and the boundary water is stopped, and it is for this reason that Feng Shui becomes very important according to the connection between mountains and rivers. Also, in this world, feng shui is everywhere, and feng shui is simply everywhere, so even in this desert of Badain Jarin, there is still the truth of feng shui, so think about it, why is water called water? ”

Da Liu and Xiao Liu were both dumbfounded, and then the two of them shook their heads together.

Gao Chao then continued: "Water is flowing, only flowing is called water in feng shui, a pool of stagnant water has no meaning, just like this sea, although it is a miracle in the desert, but it is still flowing, I am thinking, in fact, this sea itself is not moving, what is really moving, is actually something underwater." ”

"Something underwater?" Da Liu exclaimed: "Is there anything else under this water?" ”

Gao Chao nodded and said: "The reason why water appears in the desert is not because these waters are accumulated in the desert, but because under this desert, there must be a dark river, so at a specific time, the dark river tide surges, plus in a certain place on the surface, there may be a water mouth that we can't see, so these waters will gush out of the ground from the dark river through the water mouth, forming these sea children, and the sea children move, it is likely that there is some kind of magnetism in the water of these dark rivers, when the dark rivers flow underground, The water on the ground cannot immediately return to the dark river, so it will be driven by the underground dark river, so that it moves back and forth on the desert, but no matter what, their movement is regular, and the law is nothing more than the flow direction of the underground dark river. ”

Da Liu finally seemed to understand something, and couldn't help but exclaim: "So that's the case?" That...... Does this dark river mean a lot to us? ”

Gao Chao nodded and said: "Of course, I just let you see the mountains on the desert, in order to find the relationship between the dark river and these sand mountains, if my guess is correct, it is this winding sand mountain and the underground dark river that has a connection, which is also what Feng Shui says, two waters sandwiched by a mountain, or two mountains sandwiched by a water." ”

Xiao Yanagi said at this time: "That old Gao, there seems to be only one dark river in this place, right?" ”

Gao Chao glanced at Xiao Liu and said: "That's right, I observed that there is only one in this place, so theoretically, on the other side of this dark river, there should be a mountain range formed by a sand mountain." ”

Da Liu hurriedly looked to the side when he heard this, but scratched his head and said, "But it's strange, there are no mountains formed by sand mountains on this side." ”

Koyanagi also said: "Yes, not to mention the mountains, there is not even a sand mountain, it seems that the terrain is still very low here." ”

Gao Chao smiled and nodded and said: "You are right, this side looks like this, it does feel that the terrain is lower, this is unreasonable, two mountains and one water, if the water can flow under this desert, it must follow this principle, but now, there is only a mountain range on the west side, but there is nothing on the east side, but this underground river does not flow to the lower ground, you say, why is this?" ”

Da Liu and Xiao Liu glanced at each other, both a little embarrassed, Da Liu said directly: "Old Gao, Captain Gao, you can tell us the answer directly, we are also in a hurry." ”

Gao Chao was a little embarrassed, he always liked to sell off when he spoke.

So he could only hurriedly say: "Okay, in fact, I suspect that the reason why there is such a situation means that there must be a hidden mountain range under this desert that we can't see, or ...... A very large underground structure. ”

Da Liu and Xiao Liu finally understood.

Da Liu immediately said: "I understand, maybe on the east side of this dark river, the whole is an underground building, so this dark river will flow between two mountains and one water, isn't it?" ”

Gao Chao nodded and said: "It should be like this, otherwise according to the theory of feng shui, as long as there are mountains, it is impossible not to have star peaks, so I think there is an article here." ”

Da Liu jumped up happily: "Great, we found the underground building, and finally found it." ”

Xiao Liu said helplessly at this time: "Da Liu, isn't it too early for you to be happy now, even if we find it now, we can be sure that there is a building underneath, but how can we get in now?" ”

Da Liu said angrily: "Nonsense, isn't there you?" Aren't you kid an expert at blasting? If you blow it up and put a shot, won't it go down? ”

Xiao Liu said with a look of embarrassment: "I said Da Liu, do you not have a backache when you stand and talk, do you think I am the grandson of Tuxing, just go down when you talk about it, don't you have to find the blasting point?" You can't just throw it anywhere, and let me tell you, I don't have a lot of explosives with me, so I might not be able to blow it up if I put it all there. ”

Da Liu was stunned for a moment and said, "I grass, didn't I ask you to bring all the explosives?" How many did you bring? ”

Koyanagi said, "I want to bring them all with me, but do you know how heavy that is?" More than 60 kilograms, you think I'm superhuman? Most of them were left in the car. ”

Da Liu grabbed Xiao Liu's collar, bared his teeth and said, "You kid is awesome, dare to talk to your superiors like this, do you believe that I will fix you?" ”

Xiao Liu didn't show weakness, stared at his little eyes and said: "I'm grass, don't pretend to be a calf with me, your kid will be here for two years longer than me, and you're still a superior, and I'm also trying to fix you!" ”

The two of them don't give in to each other, and they are tense, and they are about to make a big move.

At this critical moment, there was a "bang" and a gunshot rang out.

Da Liu and Xiao Liu were both stunned, and looked at Gao Chao next to them together.

I saw that Gao Chao was holding a pistol in his hand, and wisps of green smoke were coming out of the muzzle, and then the two people understood, and as soon as they calmed down, they both let go of each other.

Gao Chao glanced at the two of them, and both of them turned their faces away angrily, obviously knowing that they were wrong.

However, Gao Chao still said: "I don't want to say more, you are all men, you are all soldiers, we have a task now, you can still fight by yourself, what kind of heroes are you?" Are you worthy of your dead comrades? Are you worthy of Xiao Wang and Xiao Pony? ”

At the mention of their dead comrades-in-arms, these two people wilted all of a sudden, and in their hearts, they have always held back a fire, and there is really an indescribable sadness in their hearts.

Xiao Liu suddenly said, "I'm sorry, Da Liu, I'm ...... I shouldn't have ......"

Da Liu also hurriedly said: "Don't say it, Xiaoliu, it's me who is wrong, my temper is too short-tempered." ”

After the two of them finished speaking, they hugged each other, and their eyes were moist.

On the battlefield, the friendship between comrades-in-arms is difficult to describe in words and words.

At this slightly touching moment, Gao Chao suddenly said: "Attention, there is a change in the water below. ”
