The little girl and Zuo Boyang rowed the boat slowly, slowly moving forward in the direction guided by Xue Lang.

Xue Lang's gaze traced the bright spots in this large area of rocks, shuttling through the cracks in the stones.

This bright spot is more than 50 meters in diameter, and it rises from under the rocks, and the water waves are scattered in all directions. Looking at it, it's like a grassland full of fireflies, or a starry sky.

However, in this beautiful picture, there is only destruction.

The point of light looks like it is coming from below, but in fact, the direction of the water is not directly from the bottom to the top, but there are traces of horizontal flow.

Xue Lang could clearly feel this.

Here, the fish and shrimp are cut off, and the corpses of fish that have rotted and only skeletons are everywhere in the cracks of the stones.

It is estimated that it has sunk to the bottom before it has drifted to the shore.

So much......

Xue Lang's gaze swept over the bones, and his heart was shocked.

This will make him believe the little girl's analysis before.

These points of light disappear when absorbed by life, and the flow of water into larger rivers brings with them huge schools of fish.

According to satellite imagery, the river has not been turbulent and suitable for fish to spawn upstream.

Emerging from the ground, it should be rich in minerals, the water is clear, and there is a great possibility of attracting fish.

Without these fish, Xue Lang believed that this was already a lake of death, and even the nearby residents would not be able to escape their fate.

It was the fish that kept going upstream, who fell victim to this disaster and gave him a chance to redeem it. Otherwise, it's really hard to predict what exactly will happen.

It's not that Xue Lang is too kind-hearted, this lake, this river, doesn't flow through Huaxia, and people don't seem to have anything to do with Huaxia. But Xue Lang can't sit back and watch his life disappear silently, even in the island country he hates, the country of rice, he will find the source of destruction, take it away, or destroy it.

It doesn't matter if it's the result of his cause, it's different from war, where civilians die innocently and their lives disappear, and he sees and knows it, so it must be contained.

Unless you can't afford it.

His thoughts flickered, and his attention was always following the trajectory of the water, ignoring the bright spots.

In just eight minutes, the air raft left the area where the light spots were dense.

The points of light continue to flow laterally in the deeper crevices of the rocks, and the flow continues.

Further, it is no longer emerging from a crevice in the rock, but a complete underground river.

Although the river channel is full of cracks, it has not collapsed.

Look at the width, there are more than ten meters, the height, half a meter away, the flow is not small, full of water, although not turbulent, but the speed is not slow.

Xue Lang's eyes followed the current, and gradually, they left the steep rock wall and paddled towards the lake. In less than twenty minutes, Xue Lang and the others rowed near the shore.

At this time, the lake became shallower, and gradually you could see huge rocks one and a half meters above the water's surface.

The underground river, on the other hand, still maintains that height, that is, at a depth of more than twenty meters below.

Seeing that Xue Lang didn't say stop, Zuo Boyang and Jasmine looked at each other and continued to row forward.

After a hundred and ten meters, they arrived at the shore, and in the dead fish floating, Xue Lang raised his head and found that he had reached the lake.

"Let's go, go up."

Xue Lang said and jumped up, landed lightly on the shore three meters away, pulled the rope, and dragged the air raft to the shore.

Jasmine and Zuo Boyang went ashore one after another, and just as they were about to ask, Xue Lang pointed to the air raft and made a gesture, and at the same time ordered in the headset: "Drill the Sky Mouse, lift the alert, keep up, we are located in the direction of you at six o'clock, two kilometers away from the shore." ”

"Yes!"

Zhang Bin answered the order, took a big bag with a gas raft, put away the gun, and ran wildly.

At this time, Jasmine deflated at Zuo Boyang, wiped the water, and was about to put away the gas raft before asking, "Captain, have you found the direction?" Is that the direction we've been coming from? ”

Xue Lang nodded and said: "There is an underground river below, the direction has not changed, it is a little curved, there is a space in the middle where it spreads, some collapse slightly, and it does not block the flow of water." ”

"It's not underwater."

Jasmine said as she took out her compass, turned left and right, and was determining the direction of the river.

It seems that he has learned the ability to see the feng shui landform of Liu Defeated City......

Xue Lang didn't bother the little girl, remembering the scene when Liu Yucheng was looking for the treasure specified at the end of the Tangram Box, and he had great confidence in finding the golden object.

If she hadn't seen something wrong with the direction of the lake, she wouldn't have come here. The exploration is all around the original base area.

If a gold object is nearby, a violent explosion causes the rock formation to break, and even if there is no water, the geological structure is loose, and it is difficult to excavate safely. Not to mention underwater.

Therefore, he had always hoped that the golden object could be near the Ichibu Spring, which was more than five kilometers away, and the ground was full of mountains, and the possibility of collapse was very small.

Without waiting for Zhang Bin to arrive, the little girl put away the compass and said: "Captain, it seems that it is really possible that it is the underground river in the first spring, but the first spring is not necessarily the outlet of all the underground river flows. ”

After the little girl finished speaking, Xue Lang's eyes were empty.

It's a big possibility, but he doesn't quite agree with it.

If it flows into the underground river in the base, that is, the underground river that forms the lake in front of you, then the drinking water is taken from the small island country base here, then there can be living people? Died early. Even if it is nourished by wood-based crystals, it is for masters, and ordinary people don't have that treatment.

However, there is a possibility that a violent shock shook some places, causing the merging of two otherwise unrelated underground rivers.

But in either case, if you follow the current, you can see the presence of crystals.

Zhang Bin arrived, and the four of them set off directly.

Zuo Boyang and Zhang Bin were in charge of guarding, Jasmine and Xue Lang were holding a compass and concentrating on exploring the course of the underground river, looking at those points of light, looking for the source of the points of light.

They walked all the way slowly, and as the terrain gradually rose, the underground river became farther and farther from the ground, and it had exceeded thirty meters.

As the depth of the underground river increased, Xue Lang felt gradually strained, and he could see the river, but the light spots were looming.

It seems that the "line of sight" through the rocks will cause obstacles, as in the Mexican country, the closer you get to the stone eggs, the shorter the distance to probe.

Isn't it far from a golden object?

After walking less than a kilometer, Xue Lang felt that he couldn't see it. In the end, even the underground river was gone.

He stopped and looked behind the route he had been pursuing, and made sure that the underground river was not a straight line, but a zigzag one, so that the kilometer was almost four kilometers away.

Now it's troublesome......

He looked at the little girl who was staring at him with a compass, shook his head, and said, "I can't see the river anymore, and I'm not sure if there are those particles in the water." ”

"Huh?!"

The little girl blinked her eyes unexpectedly, looked at the compass, and said, "How is that good?" Isn't it impossible to find a specific location? ”

Xue Lang nodded helplessly, and then asked, "Can you see the river?" ”

"Yes, I can still find the river, follow you all the way, and I didn't miss the direction." The little girl said affirmatively.

Xue Lang's eyes were empty, and he said, "Let's go, then let's see if the river passes through a spring first." ”

The little girl had no idea, nodded when she heard the words, stared at the compass and walked in front.

Xue Lang followed closely beside him, but he still searched for the underground river meticulously.

Unfortunately, he could see the depth of thirty or fifty meters, and he couldn't see the underground river at all.

They climbed a mountain and followed it.

Although the height of the underground river is not the same along the way, it will definitely not climb the mountain, it should be passed through the mountain, otherwise, so much pressure would have erupted earlier.

Xue Lang would simply give up perception. He knew that a depth of two or three hundred meters was not something he could see at all.

Before going downhill, Xue Lang determined that the front was not far from Yiyi Spring, because this direction was in the direction of Yiyi Spring.

However, the underground river is winding and winding, and it is difficult to say whether it will necessarily flow through a Ichizumi.

If it doesn't flow through, do you have to dig along the spring one step?

But in any case, let's determine the river first.

The four of them walked not very fast, and in the forest, they gradually approached the location of a spring, which was the other end of this mountain range, that dangerous area.

However, as Xue Lang expected, the underground river bypassed the Yiyi Spring at the bottom of this slope of the mountain, and it was at least two kilometers away from the Yiyi Spring.

Along the way, Xue Lang still couldn't see the spring, and he couldn't even see thirty meters underground.

The river didn't flow through a single spring, so Xue Lang's analysis stood up. One step spring is not the same thing as that underground river, only recently it has flowed together.

The little girl stood there and looked back at the direction of the Yiyi Spring on the other side of the mountain, and asked, "Captain, according to the location, the Yiyi Spring is in this direction, the slope of the mountain, shall we continue to track the underground river?" ”

Xue Lang looked at the time, shook his head and said, "The length of this mountain range is more than dozens of kilometers. Even if the underground river goes around and detours to the Yiyi Spring, I think the location is still near the Yiyi Spring, the reverse flow is impossible, the water volume of the Yiyi Spring is not enough to reach the level of power generation that we see in the base, and there is a drop, and the Yiyi Spring should be another waterway, or a tributary, the water outlet is blocked, and the diversion flows into the ground, so that it does not affect the towns outside the mountain or anything. ”

The little girl pondered, put away the compass and said, "The clue is broken, so let's go back to the spring first to see if there is anything new, I haven't carefully investigated it yet." ”

Xue Lang knew that it was useless to be anxious, since he was sure that the golden object was here, it was already a big gain.

"Let's go, go back to the camp first, it's dawn soon, go back and rest, and then study and study a spring carefully, if you can't dig up there to find it, how can you find it."

Xue Lang said and took the big bag of the gas raft that Zhang Bin was carrying, turned his head and went straight to the top of the mountain.

But having said that, according to the size of the previous four, he knew that if he wanted to dig it out in the mountain, no matter how big the project was, it would be impossible to find it, unless he knew the specific location, even if it was excavated, it would not take too long, otherwise, it would be difficult to find.
