The calculated data of each explosion point has been repeatedly calculated, and the cracks inside the rock wall also give Ning Xiaofan the possibility of blasting through the rock wall.

Bang Bang -

With the sound of dull explosions, the water surface boiled like boiling water in a pot, and the churning water continued for several minutes before finally calming down.

And that's the end of it?

There was no earth-shattering sound, and there was no imaginary scene of rock fragments flying all over the sky, except for Ning Xiaofan, who was determined in his heart, everyone present couldn't help but look at each other, and they didn't know whether this underwater blasting was a success or a failure?

"Huh! Look, the water seems to be lowered! Yang Hai suddenly pointed to the dark river channel.

Everyone listened, including Ning Xiaofan, who was stunned for a moment.

The calm water surface seems to have changed little, but if you look closely, you will find that the water level is really lowered a little, not very obvious, only two fingers wide, and it is really not easy to find if you don't look closely.

The drop in the water level means that the water flow has an outlet, and it also means that the rock wall has been blown through, Ning Xiaofan couldn't help but secretly breathe a sigh of relief, and said: "This waterway should be opened, everyone sort out the equipment and prepare to go into the water." ”

When everyone heard this, they were about to turn around and clean up, when Yang Haidao, who had been observing the water level, said: "Wait, the water is a little fast, you have to wait for the water to slow down." ”

When everyone heard this, they took a closer look at the water surface, and sure enough, the speed of the water level was not fast, but the water surface had already appeared a whirlpool of different sizes, and it was faintly accompanied by the roar of the water rushing over the rock wall.

The water is turbulent, forming an undercurrent whirlpool, and it is obviously not safe to enter the water now, so everyone has to wait for the time being, waiting for the water to slow down.

It's just that to everyone's surprise, hours have passed......

Strangely, when the water level dropped to a certain level, it seemed to be silent, and the current was still turbulent, but through the hydropower, you could faintly see the hole in the rock wall that had been blown open underwater.

The entrance of the cave is craggy, the area is not small, the diameter is nearly four meters, under the reflection of the light of water and electricity, it is like a gloomy mouth.

Waiting is a very grinding thing, in the dark and weird underground world, there is almost no concept of time, and everyone did not deliberately look at the time display on the watch, only knowing that in the process of waiting, the group has eaten four times and had a good sleep.

In the long and painful wait, the water level, which seemed to be not very moving, dropped a little, although slowly, but the explosion of the hole was less than a foot from the surface of the water, giving everyone a little hope to pass through the hole.

When everyone gathered together to prepare for the fifth meal, they heard the old king who was observing the water level not far away shouting excitedly: "It's exposed, the hole is exposed." ”

When Ning Xiaofan and the others heard the shouting, they couldn't help but put down the dishes and chopsticks in their hands and ran towards the edge of the platform.

When they reached the platform, everyone saw at a glance that the hole that had been soaked in water had been exposed.

The fat man immediately exclaimed: "Ah, the entrance of the cave is really exposed, and the fat man thought that he would have to wait for a day or two." ”

It's no wonder that the fat man sighed so much, this hole has been soaked in water, when the water level dropped, the hole seemed to be less than a foot away from the water surface, and then it dropped a little bit, and then later, the drop in the water level seemed to be stagnant.

The water level dropped and stagnated, but the water flow was still turbulent, and everyone thought that the water level drop was over, so that Ning Xiaofan and the others were secretly anxious in their hearts, thinking that they didn't know how long they would have to wait, but they didn't expect that the stagnant water level actually fell again, and the scale of the decline was not small.

At this time, everyone noticed that the water level was still falling at a speed that was visible to the naked eye, and they could clearly hear the sound of the water rushing through the entrance of the cave, and the water seemed to become more turbulent.

"I mean, the water level is going down too fast." The fat man couldn't help but mumble.

"Fat brother, isn't it good to go down faster, it's good to go all the way down to the end." Hou San on the side said excitedly.

When the fat man heard this, his little eyes blinked and said: "It's also ha, it's best to drain all the water here, hehe, at that time, the brothers don't have to dive so hard to swim over, how easy it is to walk directly from the hole below." ”

At this time, Yang Hai, who was standing quietly observing the water level, opened his mouth and said: "I'm afraid we have done something good this time, but if we don't get it right, the outpost that is half flooded, and the water level will also drop at this time." ”

As soon as Yang Hai said this, everyone's eyes couldn't help but show a hint of thoughtfulness.

The fat man's brain was bright, and he thought of something at once, and hurriedly said: "Damn, listen to Lao Yang, you said this, do you mean that the water level in this water area has been lowered?" When the water level drops to a certain level, isn't it much more convenient for other prospecting teams to explore the way, so isn't it a big bargain? ”

Yang Hai sighed and said, "I'm afraid that's the case, the water in this water area should have poured from this outlet that we blew up, otherwise, this water level wouldn't have dropped so slowly." ”

When Hou San heard this, he was a little indignant and said: "Your sister, it's easy for us to open a passage here, but it's cheaper for another Wang Balamb, this ...... That's not a good deal, isn't it? ”

"That's it, I also donated blood, why should I be a cheap outsider." Biaozi also echoed with an unconvinced face.

At this time, Ning Xiaofan frowned slightly and said, "Okay, okay, it's not cheap, it's good that we can blow up this exit." Besides, I don't know how far this water level can drop, if the water is still so urgent, we have to continue to wait, I don't know how long we will have to wait, you all stop. ”

Ning Xiaofan's words, the fat man, Hou San and the others were silent, the water level has dropped, but if the water is still so urgent, it is not suitable to enter the water at all, and they have to be trapped here and unable to move.

For a while, everyone couldn't help but be happy and dispersed.

I don't know if it's lunch or dinner, but I have to wait, and everyone gathers together to play cards, chatting and chatting, and killing time there......

I don't know how long later, when it was Zhang Chun's turn to guard the water level, he came back with a piece of news, the water flow began to slow down, and the water level dropped a lot, and half of the exposed hole was already exposed.

Zhang Chun's news lifted everyone's spirits and gathered to the edge of the platform again.

As Zhang Chun said, the water level has dropped a lot, and the craggy hole that has been blown open has been half exposed to the surface of the water, and the water has not only slowed down, but at this time, it seems to have stopped.

Has the water stopped?

Everyone couldn't help but look at me, you looked at me, and their eyes showed excitement.

Ning Xiaofan touched his chin while observing the water potential, and then looked at Yang Haidao: "Old Yang, how are you watery?" ”

"It's okay......" Yang Hai replied, with a hint of doubt in his eyes.

"You take your gear and go down the cave to see what's going on across this passage."

"Oh, understood." Yang Hai responded, turned around and went to sort out the equipment.

Seeing that Yang Hai didn't hesitate, Ning Xiaofan's eyes flickered, and then turned to Hou San and said, "Hou San, this path-finding work is your duty, you can also go and prepare, go with Lao Yang." ”

Hou San was stunned for a moment when he heard this, then nodded with a bitter face, and turned to leave.

Ning Xiaofan followed and said to the rest of the people: "Okay, everyone pack up their equipment, and when Lao Yang and Hou San explore the road, it's almost time for us to set off." ”

By the time everyone began to pack up, Lao Yang and Hou San had already equipped their diving equipment and went into the water with waterproof lights.

The entrance of the cave is halfway out of the water, and you can't use diving equipment, just swim in, and bring diving equipment to be prepared.

Ning Xiaofan had scanned the rock wall that blew out of the hole, and it was more than five meters thick, if nothing else, Yang Hai and Hou San would soon be able to walk through this passage.

Sure enough, everyone packed up and didn't wait long on the shore, Hou San's figure was revealed at this end of the cave, but Yang Hai's figure was gone.

Without waiting for Ning Xiaofan to ask out loud, Hou San said excitedly: "It's through, over there...... It's so big over there, you can't see the ...... at a glance."

When the fat man heard this, he hurriedly asked, "Can't see the edge at a glance?" You dead monkey, let's be clear, what's the size? Is it dangerous? What about that guy Yang? ”

Hou San swallowed his spit and said, "Fat brother, it's a lake, there's a big lake over there, the area is very large, it's as big as the sea, it doesn't look dangerous." Lao Yang was waiting at the other end of the cave entrance, but he didn't follow, by the way, Lao Yang said, I have to prepare the rubber boat. ”

The Great Lakes? After listening to Hou San's words, everyone couldn't help but look at each other, this underground is evil enough, there is actually a big lake, as big as the sea?

But no matter how evil it is, it has to be faced, Ning Xiaofan didn't say much, and immediately beckoned everyone to bring their equipment and go into the water.

Although the entrance of the cave is half exposed, the hole that was blown open is about ten meters deep from the bottom of the rock wall, and everyone has to swim a short distance, and after entering the cave, the depth of the water is also neck-deep.

Everyone entered the cave one after another, and the length of the cave was only more than five meters, and soon they flowed to the other end of the cave one by one.

Yang Hai was waiting at the other end of the hole, his body soaked in the water, only his head above the neck was exposed. Through the entrance of the cave, there is a vast black area outside the cave, and it is not clear to see the true face of the so-called big lake.

Ning Xiaofan was about to step out of the hole, but was stopped by Yang Hai: "Be careful, don't step into the air, the water is deep." ”

Ning Xiaofan was stunned for a moment, and then reacted, this passage is not at the bottom of the rock wall, since it is a big lake outside, there is naturally no place to stay, and if you step out, don't you have to step into the deep water area.

Of course, Ning Xiaofan has excellent water quality, and he can't drown even if he steps on the air, but there is no need to go to the deep water.

The waterproof flashlight in his hand swept around the outside of the cave, and under the reflection of the flashlight, there was a vast water outside the cave, sparkling and vast. At the end of the pillar of light, I can't see the edge, and I don't know where the end of this water is?
