Hearing me say this, the seventh master was also stunned, and hurriedly turned around and asked, "What?" What's the problem? Did you find something? ”

I hurriedly shook my head, "It's not that I found anything, but there is a problem that I can't figure out." ”

The Seventh Master asked, "What's the problem?" ”

"Since this ancient tomb is under this Laang Tso Lake, is the entire tomb flooded? Since there is a thousand-year-old ice layer down there, if it had been soaked in water, it would have melted a long time ago. ”

The Seventh Master smiled slightly, shook his head, and said, "I have also considered this problem, and after going down, you will understand, at the bottom of this Laang Tso Lake, there is a very thin stratum corneum, about nearly a meter thick, I don't know how it was formed, and I don't know what substance it is, in short, as long as it passes through the stratum corneum, there is a large space below, and the thousand-year-old glacier is under this stratum corneum." ”

After the seventh master finished speaking, we have arrived at the destination, Huzi drove the car to the bottom of a dirt slope, and after unloading the equipment from the car, he began to shovel the soil on the soil slope with a sapper shovel, preparing to hide the whole car.

The seventh master has already begun to change into a diving suit, and after Huzi has finished hiding the car, the seventh master has already squatted there and waited.

At this time, I wanted to smoke a cigarette to relieve my nervousness, but as soon as the cigarette was taken out, I was stopped by the seventh master, "Don't smoke, there is no end here, there is no shelter, you can see this smoke from several kilometers away." ”

After such a reminder from the seventh master, I hurriedly put away the cigarette, and when Huzi changed into a diving suit, half an hour had passed, and the four of us moved our bodies, came to the lake, and prepared to dive.

The seventh master helped us check the diving equipment one by one, and after making sure that there was no problem, he said, "It's too dangerous to carry the equipment directly, use the climbing rope to tie up our equipment first, and then pull the equipment down when it reaches the cuticle." ”

I nodded, and after tying up the weapons and equipment according to the method arranged by the seventh master, I handed the climbing rope to the seventh master.

The seventh master took the climbing rope, nodded, and took the first step into the lake, I saw that after the seventh master got in, there was no figure at once, only the climbing rope was still slowly down, I was afraid of the water I am now more and more nervous, a little cringe, but was kicked by the tiger and staggered forward several steps, the foot was unstable, and he was planted into the lake.

After entering the water, I turned on the underwater flashlight as fast as I could, and shone forward, although the water was very clear, and there was no turbid floating, but the seventh master in front of me still couldn't see his figure, only a climbing rope floating around in the water.

Then Huzi and Wang Chuyi also jumped into the water, Wang Chuyi swam to me, pulled my arm, pointed to the climbing rope, and signaled us to follow the climbing rope downstream, it should not be wrong.

After swimming for a while, I finally saw the figure of the seventh master not far away, only to see his whole person stop there, his hands kept dancing, he should have noticed the light behind him, the seventh master immediately turned his body and made a gesture to us to prohibit traffic.

As soon as he made this gesture, I immediately felt bad, I should have encountered the undercurrent that the Seventh Master said before! It's just that I don't know where this undercurrent is, whether it is in front of the Seventh Master, or between us and the Seventh Master, in short, under the reminder of the Seventh Master, none of us dare to swim forward.

The water temperature here is very low, and if you keep swimming, it's a little better, but after a cold stop, after two or three minutes, I feel cold.

Fortunately, the stay here was not long, and after a while, the seventh master waved his hand at us, signaling us to go over, and when I swam to the seventh master, I gestured to him and asked him if he had encountered an undercurrent.

The seventh master nodded, pointed underneath with his finger, and signaled that there was still a lot of depth, let's follow closely.

In this way, we followed the seventh master all the way downstream, about ten minutes, and arrived at the entrance of an underwater cave, at this time the seventh master stopped, and carefully shone it in with a flashlight, I could vaguely see through his diving goggles, his expression was very unnatural, as if he was surprised to see this hole.

At this time, I chuckled in my heart, the seventh master on the shore said that he had been here once, so he shouldn't show such a look, right? Could it be that the cave he had been to was different from what we see now?

At this time, the seventh master was also stunned, and just used a flashlight to shine towards the entrance of the cave, and there was no further movement, and the three of us were furious in our hearts.

You must know that we are not leisure diving, but in a very low temperature saltwater lake diving, and there is an underwater cave, this cave diving is not ordinary people can do, especially for some unknown areas of the cave, but also to be cautious, because the mortality rate of cave diving is very high, according to survey statistics, although the number of cave divers only accounts for 1/10,000 of ordinary divers, but the probability of accidents accounts for most of the diving accidents.

Looking at the unfathomable hole in front of him, the seventh master also hesitated, stayed for a long time, and finally waved his hand at us, signaling to go back to the shore first.

Immediately afterward, the seventh master quickly swam upstream, I saw him swimming towards the water, there dared to stay here alone, immediately followed him and began to swim upstream, the buoyancy of this saltwater lake was much greater than that of the freshwater lake, and it was almost effortless to swim upstream, and soon we returned to the shore.

The seventh master quickly took off the diving suit and said, "Hurry up and check the equipment and do a good job of oxygen supply!" In an hour, let's go again! ”

When the seventh master spoke, we barely had time to pause, and hurriedly checked our equipment again, and then took a new oxygen tank and replaced it.

After everything was prepared, the seventh master said, "This cave entrance is still the same as before, it won't be wrong, but there should be a change inside." ”

I was stunned for a moment, and then asked, "Seventh Master, how do you know that there has been a change inside?" When I was at the entrance of the cave just now, the light of the flashlight couldn't shine far at all, and the general situation inside couldn't be observed at all. ”

The seventh master sighed and said, "Like this kind of hole, even if it is an experienced diver, he does not dare to rush into the water, the last time we dived in, it was also an experienced old diver, with the guide rope in the first step, let the guide rope be arranged, and the people behind only need to use a small wire wheel to connect with the main rope from outside the hole." Just swim inward. ”

Hearing this, I couldn't help but be stunned, and quickly asked, "You mean, the guide rope is missing?" ”

The Seventh Master nodded, and then said, "This place is called Ghost Lake, even if there are occasional tourists who come to visit, they will never go down with diving equipment, plus there is an undercurrent surging underneath, and if you are not careful, you will die, even if there are a very few diving explorers who go into the water, they will never go to that hole." ”

The seventh master said this very urgently, and it can be seen that his heart is very entangled, but at this time, what is even more entangled is me, if the seventh master says so, the guide rope will never disappear for no reason.

Now there are only two possibilities, the first possibility is that someone has already entered, most likely the people of the Sky Wolf, and they have put away the guide rope after entering.

The second possibility is that the guide rope has corroded itself and cannot find the slightest trace.

However, the second possibility is very small, such an underwater guide rope is made of special materials, not to mention corrosion, even if more than ten years have passed, it is still intact.

Now that we have all calmed down, there is no guide rope in the cave at the bottom of the lake, and this is a big problem, you must know that ordinary diving is generally in open water diving, if you encounter problems during diving, you can immediately rise to the surface, breathe the air you depend on, even if the equipment fails, there is enough light to deal with the problem and find a diving partner.

And once we enter the cave, everything changes, that is, diving in a dark covered space environment, the error tolerance rate is very low, once we lose the limited air or limited lighting, or lose the guide out of the cave, and can not leave, then there is only one result waiting for us, that is, suffocation.

I didn't expect to encounter such a tricky thing when I first arrived here, and the trickier thing is a potential danger, that is, the team of the Sky Wolf!

We have all been too smooth along the way, and the wolf who has always been eager to repay the situation, since he let out the wind and said that there is a unicorn eye hidden in this ancient tomb, and he also knows that that thing is very important to us, he will never sit still, this is not like his style.

But until now, our group has not received the slightest obstruction, everything is too smooth, and it is too calm, the more this is the case, the more bottomless our hearts are, who dares to say that this underwater cave is not a calm wind? If they were waiting for us at the end of the cave, we would not even have the power to resist, we would all be lambs to the slaughter!

Thinking of this, I couldn't help but shudder and turned to look at the Seventh Master.

The seventh master frowned, it seemed that he should have the same concerns as me, he slowly put on his diving suit, coughed and said, "Bring a saber with you, don't be soft in case of emergencies." ”

As soon as the words fell, the seventh master came to the lake again, then looked at a few of us, and then said, "The guide rope will not disappear for no reason, I estimate that a group of tomb robbers have already gone down, as for whether it is the team of the wolf, it is difficult to say now, if it is, then we will consider ourselves unlucky, and we will break his two teeth desperately, if it is not ......" The seventh master snorted coldly and made a gesture to wipe his neck.

At this time, Huzi smiled and said, "Since someone has already gone down, it must be a wolf, otherwise who else will there be?" ”

At this time, Wang Chuyi, who had not spoken, stepped forward and said in a calm tone, "Borrow a knife to kill!" ”

As soon as these words came out, Huzi and I were shocked, and the seventh master also nodded with a gloomy face.
