In all movies, falling into the water must meet a waterfall. It's only today that I'm sure that the film is really from life, and the smooth sections and deafening sounds all indicate the existence of the waterfall ahead.

This kind of underground environment is prone to some extreme terrain, and it is impossible to imagine how high this waterfall can be, and judging from the place where we just fell, the scale of this waterfall is not very small. I struggled to shove little Adam into my bag, ready to fall. It's completely different from what happened on that mountain, and I can't do anything with this kind of rushing water.

Liu Dongxi still did not give up his efforts, and threw the pulley crossbow in his hand towards the rock wall. This trick is also ingenious, and it is very accurately stuck in the rock crevice. The rope at the other end should have a quick hanging somewhere, I cheered in my heart, and I was ready to grab Liu something. I didn't think that the rope could not hold this kind of power at all, and with a bang, it danced wildly and shook my ears and went backwards.

This last effort came to naught, and I shouted, "Dive down!" He took a deep breath and dived into the water, followed by a feeling of weightlessness.

When I emerged from the bubble, I saw that the heads of the other three people were also floating on the water. This waterfall was not like the three thousand feet that we thought, but a mound two or three meters high, and I dived into the water with my own cleverness, and not only did it not play any protective role, but also hit the bottom of the rock.

The four of us finally got together and tied each other up with a quick hanger, and it was a horrible situation to get separated in this environment anyway.

God knows how this waterway can be so smooth, and I don't know where so much water comes from in the winter, and I don't feel like I'm drifting underground, but a little like I'm sliding through my veins. Perhaps this kind of place is the vein of this land, and we walk through it, not knowing whether it will be treated as nutrient absorption or as if it will be treated as an invader who died at the hands of white blood cells. I gave up my extra resistance and tried to keep my eyes open, and the walls of the cave often showed beautiful colors at high speed, and I couldn't even make out what they were.

The drift lasted about forty minutes, and I felt a sudden emptiness in front of me, and I rushed out of this long pipe. But it's still dark outside, I'm not sure if it's outside, even if it's late at night, it's not such a dark night.

The surface of the water had widened, the current had begun to slow down, and my feet had touched the ground from time to time, and Lu Yan turned on the flashlight again, and the light shone far away. We vaguely saw the riverbank and swam desperately in that direction. Because my hands and feet were frozen before, I couldn't listen to the call, so I had to swim very hard. Halfway through the swim, I felt a little overwhelmed, so I buried my face in the water to save some effort.

At this time, I suddenly had the feeling that something was peeking at the bottom of the water, and I was shocked, I knew that it was wrong, but I didn't dare to open my eyes to see it, but I just swam forward quickly with my hands and feet. But the feeling of being watched grew stronger and stronger, almost like an awl piercing my eyelids. I couldn't bear it anymore, and opened my eyes suddenly, it was pitch black under the water, and the light of Lu Yan's portable flashlight was scattered, which was basically ordinary sand and gravel.

I should be too nervous and a little nervous. I widened my eyes and searched without finding any clues, and then I felt that my eyes were hurting and I hurriedly closed my eyes. It didn't matter if he closed his eyes, a long white face suddenly appeared in front of him, and his black hole eyes were full of grief and reluctance.

I was so frightened that I couldn't hold my breath anymore, so I choked on a mouthful of water, but fortunately I reached the shore in front of me, and I slammed my hand on the stone, and I didn't care about the pain, so I quickly grabbed it and climbed up.

There were all kinds of rocks on the shore, and I had just looked around, but the lights went out, and the white face suddenly appeared in front of me again!

This surprise is not trivial, but I stabbed my sword in the air! At this time, the white face moved along my line of sight, and I realized that this was just a visual image, and although I don't know how it was produced, it would never cause me any harm. So I didn't care about him, and let that white face slowly fade in front of my eyes.

There was a soft sound next to him, and Liu Dongxi ignited a fire. The only thing we didn't get wet with water was the things in the waterproof bag, and Liu probably set my notebook on fire.

"What is this place? How can you be so depressed. Liu Shidong snorted.

I lit the fire and saw some dry branches around me, so I hurriedly took them and handed them to Liu. The fire soon ignited. We dragged a half-dead tree from a short distance away, and cut down the wood little by little to make do with it.

As the fire dried, I felt a little relieved, so I took off my clothes and baked them. Little Adam had already stretched comfortably by the fire.

"What is this place?" Wang Dake asked.

I think she has a very second question, and she doesn't bother to answer it at all. Who knows where we are now?

Liu Dongxi thought hard, "We are about ...... west of Xiazhuang."

I seemed to see Lu Yan smile, and Wang Dake looked at him directly with disdain, turned around and pulled the bag, and then turned around and found the box that would explode.

Is this what it's about? I was a little uncomfortable but didn't show anything, just looked at her closely. This box is worth a lot of money, and few people will run around like this, and he can hold this thing probably related to her mission, and he doesn't know what will be in it.

Wang Dake didn't enter the password as carefully as I imagined, but didn't care about turning on the switch directly and opened the box, there was nothing strange in the box, only a yellow handheld GPS lying inside. Wang Dake smiled at me, "Fourth brother, I lied to you before, and this box didn't start at all." ”

I was upset, but I waved my hand to show that I didn't care, after all, it was really not interesting to care about those little things in such a place. Wang Dake picked up the GPS and operated it for a while, then frowned and said, "This underground is too deep to search for stars at all." "I already knew that this was the result, I used to go out to play, and I couldn't find it at all, let alone in such a deep underground.

Wang Dake was still shaking there, and I felt a little strange, so I asked, "Haven't you used GPS before?" How is it possible to find stars in such a place? ”

"This GPS is different from the civilian kind, and I have used it underground, so there is no problem at all."

"Dake, the kind of underground you are talking about is not the same concept as our underground!" Liu Dongxi said.

"What's the difference, this machine can also be located by the characteristics of the geomagnetic field, but it is not so accurate!" Wang Dake argued with himself.

"Really?" I'm in awe, has science reached such a level of science fiction now?

"Of course it's true, we collected the geomagnetic features of this piece before we came in, and all of them were stored in this device, and then it will locate it according to the characteristics of our location." Wang Dake said this like a salesman, and added: "But this thing is not accurate enough, and the error will be around a few hundred meters." ”

I've always been very interested in this thing, and I leaned over to her to see it clearly, and Wang Dake also handed me the little thing, only to see that in the grid on the small screen, a black dot kept running around, and a bunch of parameters were scrolling wildly on the side.

"What is this?" I asked.

"It's positioning!" Wang Dake stretched out his head to take a look.

I said yes and continued to look at the light, and the dot flew around like a headless fly and finally landed in one place, making a dripping sound.

"That's it!" Wang Dake snatched it back, "You don't understand ......"

Wang Dake swallowed it back halfway through this, with an extremely frightened expression on his face.

I didn't know what was going on, so I hurriedly took it and looked at it, but I couldn't understand it, and when I was about to ask, a few words popped out of Wang Dake's teeth, "It's at the bottom of the lake!" ”
