Dongfu climbed along the rumble for a long time, the muddy and sand-covered water almost covered his head and face, and he held his breath and advanced forward for hundreds of meters, the hole was so narrow that he could only barely pass forward by turning sideways. The sound of the water is loud, the water flow is rapid, Dongfu took a lot of effort, and finally climbed to the end of the narrow hole, the terrain at the end of the hole changed abruptly, the entrance of the hole was like a slender and long narrow line, like a thin slit in front of Dongfu, nearly three or four meters long, only thirty centimeters high, the water flow and sediment were rushed into the tile from this crack, such as a bell mouth was collected by the tunnel and flowed down the tunnel.

Dongfu approached this slit, stretched out a hand to lift the ice crystals out of the slit, and his eyes were inherently stronger than them, but he still looked at it carefully for a long time before he could vaguely see it, and he was suddenly shocked.

In the place where the faint light of the spar outside the stone crack shines, there is obviously a huge platform, and the edge cannot be seen clearly in the darkness, but you can see a huge stream of water falling from the sky not far away from a hundred meters, it is a magnificent waterfall, and the sound of the water flow is caused by the fall of this waterfall. The front end of this platform is extremely wide and long, like a sharp blade inserted into a waterfall, and part of the rushing water falls fiercely on the protruding platform, splashing and overflowing. The sound was deafening. And outside the platform should be a larger and huge natural cave, the sound of the waterfall after flowing down the rumbling echo in the cave, endlessly. With the water rushing in, the cold breeze continued to pour into the cracks of the stone, making a whining sound.

This is obviously not something that can be done manually. Dongfu was shocked by the magic and brazen momentum of the heavens in this natural world, and lay on the edge of the stone crevice to observe for a long time, thinking that this day had been out for too long, afraid of cold ice and worry, and finally pressed the curiosity in his heart, still went back along the road, and called Qingqing back to the cold ice cave together.

When I went back, I talked about the wonders and ice I saw, and I thought that the water flow of the waterfall on the cave was already turbid, which caused the water flow to be muddy in the cave.

I don't know how high this waterfall is? How big is this cave? Is this waterfall pouring down from the dark river on the top of the cave? With such a big current, I don't know how the dark river is surging. The cave was so dark that it must have been in the depths of the ground. How did the ancestor of the cold ice discover this big karst cave?

Dongfu is like a child who has discovered a new world, his mind is full of the mysterious cave, and Han Bing has been talking about this mysterious underground world, and he can't wait to go back and explore it again immediately in his excitement. I also thought that if I knew the thickness of the platform, it would be best to dig a pool on the platform, because when the waterfall falls, the water will first flow into the pool, and then overflow after precipitation, so it may not be so turbid.

Han Bing wiped the scratches on his face and body that he accidentally cut when he crawled through the tunnel with mugwort oil, and smiled to soothe: "Have a good rest today, you will go earlier tomorrow, and now that you are familiar with the road, you will be able to walk faster, this water has been clear in previous years, maybe it is only the recent heavy rain that has muddied the dark river, and it will be clear again in a few days." ”

I remembered that Dongfu said that the cave was too dark, and I went to the cryolite accumulation place, and after looking for a long time, I finally turned over to two stones that were very good and bright, round and slippery, just enough to hold, and there was a hole, which could be hooked with a finger and would not fall, which was very convenient, and the white light was shining in the hand, like a small moon.

"This stone was originally left by the ancestor of the master, and it should have been specially polished for illumination. It's exactly a pair. I played with it when I was a kid, and I can't remember it if you don't say it. Tomorrow you can take this to the stone platform, and it can also illuminate the surroundings. ”

Dongfu is very happy, this stone is like a lantern, the white light is soft, and it is very firm to hook the finger while taking advantage of it. It can also be tied with a thread.

Han Bing wrapped the other one firmly with ice silk, and knitted a hood with ice silk. Weave the ice-stone lantern into the hood. She has very clever hands, and after half a night's work, she has done it. Dongfu woke up from sleep and saw that Han Bing was trying to size his head on his head, so he hurriedly took her hand distressedly: "Don't be tired, you hold your stomach, or rest early." ”

Han Bing pursed her lips and smiled, taking advantage of the situation to put it on Dongfu's head, she also tied two thick straps, Dongfu put this hood on, and then fastened the strap under his neck, it was like wearing a cool hat, and it was still a hat with a headlamp. In this way, whether it is sideways or prostrate, it does not matter, one can be tied with ice silk and hung on the hand, and the other can be worn on the head, which is extremely appropriate.

So on the second day, Dongfu was fully dressed, fed and drunk, and went on the road of water source remediation in high spirits.

Before leaving, he didn't forget to hug Han Bing in his arms, and listened carefully to Han Bing's belly for a long time, and laughed softly: "But be obedient, don't kick your mother lightly." ”

Han Bing smiled and stroked his stomach: "I have been playing especially happily in the past two days, one time on the left and one on the right, very skinny, maybe a kid." ”

Dongfu couldn't help but squat down again and listen carefully, and his heart was extremely happy: "The boy and girl are all good." Daddy loves it. ”

Han Bing took out one of the lotus root pieces and said, "You still go with Qingqing, I will make the lotus root stewed rice, and then ask Qingqing to come back and carry it for you." “

Dongfu carried a pot of water splash on his waist with a leather bag, and advised, "Don't be too tired, I'll just get down." ”

As he spoke, he pulled Han Bing and hugged him, kissed him on the face, and then strode out.

The water flow on the lotus platform is still turbid, and Dongfu is full of confidence that he will be able to solve the problem of this water source.

Unexpectedly, there was no turning back.

It took Dongfu two hours to climb to the end of the water source and the source of the water found yesterday, in front of the narrow stone crevice. He took out the pickaxe he had prepared, knocked out a hole, and drilled through it.

The platform connected by the stone cracks is huge, and I am afraid that there are hundreds of square meters. Coming out of the tunnel and entering this vast platform, the sound of the waterfall falling into the water is even more deafening. In addition to the sound of water in the cave, there is also the sound of wind whimpering, and the cold invades people. The air was filled with the smell of water and a strange smell of sourness, and the platform beneath his feet was covered with slippery moss, a few inches of thick dirt, and he slipped three steps in one step and sunk deep into one's feet.

Dongfu walked to the side farther away from the water, looked down, the bright white light of the spar could only shine near, and vaguely saw the craggy mountain connected by the platform down, like a cliff straight down, and then down the dark darkness like the mouth of a monster, throw a stone down, and carefully distinguish it for a long time, and you can't hear the echo of the landing at all, which is unfathomable.
