I followed her gesture and looked around, and found that the group of seven people had already gotten into the dark water, and those with searchlights had already turned on and groped around. Pen & Fun & Pavilion www.biquge.info but the range of underwater light is limited, and it is not true to see it from a distance.

Suddenly I realized something was wrong and looked around. That's right? Why are there seven? I, Huzi, sick beauty. Monk, big strong, steamed buns...... There are only six people in total, how can it be seven?

I was gesturing in the water, and everyone looked at me suspiciously, and when the monk's searchlight hit my right hand, I made a '7' gesture to him, and then pointed to the seventh black shadow.

The monk turned his head to look, obviously startled, hit a few big blisters in his mouth, and hurriedly came to me. The black thing was motionless, and the monk held a searchlight and hit the thing, as if the thing was very afraid of the light, and twisted its body and swam out of the range of the light. Just that moment, I saw the thing clearly, the black body, the surface was shiny, there were hands and feet, I don't know what kind of monster, this moment scared me to choke a few more mouthfuls of water.

I dived for about 2 minutes, and I felt my lungs swell so badly, my head started to get dizzy, and I couldn't hold on anymore, so I desperately went upstream to get out of the water. There was another burst of darkness in the thick fog on the water, and although the air in the fog was viscous, it was not so bad that I couldn't breathe, and I took a few greedy breaths.

Now I really envy them for a few of them who can 'turtle breath gong', this breathing method necessary for going into the water, no matter what, it must be practiced, and it will not be the hind legs of the old people in the water.

After a large breath of air into my lungs, I went into the water again. At this time, I found that the water level was already very high, and I slightly estimated that eighty percent of the entire chamber had been overflowed by the sea, and if I could not find the exit, I am afraid that the first person to drown would be self-evident.

The tiger, who was not far from me underwater, gestured to me to ask me how I was doing. Then I did a few turtle breathing postures. At this moment, I really doubt that this 'Huzi' is really my brother? Otherwise, this anxious look, as well as the starting style of the turtle breath gong, are the same as the tiger in my impression.

Whether it is a tiger or not, if you don't find an exit, then everything is meaningless.

The sick beauty was so fast underwater that she swam out of the aperture of the searchlight, and I think she must have been looking for a way out of the wall. The instinct to survive caused us to scatter and separate, each groping for the wall. Naturally, I am no exception, but the seventh shadow that appeared in the darkness is also in this secret room, and this feeling of thorns in the back is not impermeable.

I dived down and groped for the stone wall to the south, and not far away the tiger looked at me, and the cat swam towards me, he followed me with a searchlight, and I groped for the neatly arranged bricks on the stone wall.

The wall layout is clear, and the specifications are neatly arranged. I stared at the cave as I fumbled for the walls. I found that this kind of brick is very cumbersome in architecture, generally the ancient building is built in a solid and atmospheric layout, it is impossible to create such a trivial and small brick, if you want to be beautiful, this kind of yellow and blind brick has no aesthetic at all, how to look at it feels very awkward.

Just about to turn his head to see Huzi's situation. When I turned around, I suddenly found a black head in front of me! Because the thing was carrying the halo on the tiger's side, the whole face couldn't be seen really, but this was a big face, and it was estimated that the whole face was more than half larger than mine.

In fact, since I entered the water, I have never seen any terrifying and hideous grimaces, and at this moment, this strange face immersed in the darkness is really scary enough for me. It's no wonder that what often happens to people is not terrible, but what is terrible is not knowing what will happen.

I shuddered, and jerked back, and the black monster came close. In the darkness, the monster stretched out a long tongue and swayed and wriggled in the water, like a red water snake spitting apricots at me.

I was already frightened, and I saw the glow of the searchlight in front of me flickering. The tiger behind the monster smashed it on the head, and there was a lot of resistance in the water. The searchlight hit the monster's head with no lethality at all, but it turned its head excitedly, and for a while the blisters jumped and pounced on the tiger.

I rushed up from behind, and because I was in the water, my speed was naturally greatly reduced. I threw myself into the air and squinted to see that Huzi was already scuffling with the monster, and the two bodies were rolling in the water, swinging in circles of churning waves. And over there, Huzi's searchlight gradually sank out of his hand, and suddenly it was dark all around.

I hesitated for a moment whether to dive down to chase the searchlight, or go up to help Huzi? Only one was stunned, made a decision at the moment, and rushed up to help. Whether he is a tiger or not, after all, it is a human life.

I kicked under my feet, rushed up a few meters desperately, took out my spear and stabbed it in the direction of the black shadow. I felt a small sound in front of me, and I thought that the knife had entered the flesh. Before I could do a few more blows, I felt a huge push hit me, followed by a huge force on my head. This smash made me dizzy, and the force was very strong, and it knocked me down and sank to the bottom of the water for several meters. Immediately after that, the nose, ears, and mouth were filled with several mouthfuls of water.

My head hurt so badly that I immediately realized that the air in my lungs had been depleted, and my forehead was sticky and felt hot. The instinct to survive made me fight to the death, and when I was sinking, there was a slowly falling searchlight next to me, and I reached out and pinched it, and shone the searchlight upwards.

The first time I looked at Huzi, he was clutching his chest and looking pained, and the monster was somehow gone. I turned the searchlight up again, but to my horror, I found that the water level had reached the top, filling the entire chamber, which meant that I had no more air to suck.

The blow made my spirits panic, and at this moment I felt a warmth on my face, and I reached out and touched a handful of them on the searchlight, and the blood on my hands rippled in the water. Now the pain in the seven orifices is terrible, could it be that I have held my breath for too long and have not breathed, and my body functions have begun to be damaged?

The dizziness in my brain became more and more intense, and soon my consciousness was blurred. At this moment, I felt that my body involuntarily became very light. Doesn't it seem like I'm really fit to get into the water? I said this to myself, and my body sank, and the darkness around me came rushing over me endlessly......

I felt as if I saw my sister's face weeping in the dark, and I felt as if I saw my mother crying in the distance......

In the dark, a black silky mass of something draped down my face and stroked my cheeks. I was so frightened that I opened my eyes, and found a cold face on my face, too dark to see really, only to feel that the surrounding was black dancing silk, around my nose, itchy I subconsciously inhaled, and suddenly the sea water poured in, choking I almost turned my back on the breath, but somehow, it seemed that the sea water poured into the nose and the familiar fragrance of lilies......

I felt a mouthful of oxygen pass through my mouth, and I was instantly shocked. Instinctively, he stretched out his hands, hugged the object in front of him, and gulped down oxygen. The man's body trembled, and the silky filaments seemed to be a little messed up, floating in the water.

I didn't have to take a few breaths of the oxygen that the man had crossed. Good fellow, the man kicked me in the waist and abdomen, and my whole body was kicked and sank, and I choked violently, so that I didn't swallow the water, otherwise those few mouthfuls of oxygen would have been in vain.

After the stingy fellow's kick, I was already near the lower end of the chamber, and the sunken searchlight was at my feet, and I bent down to pick it up, and flew up again with the searchlight. When I swam to the platform, I looked around with the help of a searchlight and found that the condition of several teammates was no longer optimistic. Several of their bodies trembled and twitched in the water, afraid that this would only happen under extreme lack of oxygen. Especially the monk grimaced in the water with a hideous face, and his mouth was open and shaking like a hanged ghost!

I reassured myself and estimated the amount of oxygen I had just crossed, and I could only hold my breath for less than two minutes at most, and now that the situation was extremely urgent, how could I find an exit in these two minutes.

What's more, there is a seventh shadow staring at this space, and the blood in my seven orifices is seeping out. At this time, it was as if something flashed through my mind......

Seven!? Seven tricks? The seventh shadow? The seventh change? 142857？ The seventh change in this set of numbers? Seven? The numbers of 142857X1-6 are all numbers that change 142857 arrangement, why do they change the numbers when multiplied by seven? 142857X7=999999

All 9? It's all 9!

Is that so? Is that so!? I quickly swam to the corner of the wall with a searchlight, and wiped away the blood from the seven orifices, and my head hurt terribly. But here's the point, I've got the answer to this riddle! I had swept over the wall at great speed, mentally counting the number of bricks on the wall, 500 horizontally and 500 vertically, and sure enough!?

I was anxiously doing mental arithmetic on the side of the wall, when the sick beauty also came to my side, looking at the bricks on the wall with a pair of eyebrows. At this time, I was too lazy to take care of her, I didn't have time, I swam through the mental arithmetic on the side of the three walls, and when I came to the fourth wall, I felt that I couldn't hold on anymore, and my lungs throbbed for a while because of the lack of oxygen.

It's really different! There is a brick missing from the corner of the fourth wall. It turns out that each wall is 500X* equal to 250,000 bricks, and one of the walls is missing one, and the sum of the four is exactly 999999. That is, the variable of 142857, then the mechanism must be in the last place without bricks!

I gritted my teeth and swam towards that place, but the distance of a few meters was as far as the end of the world, the corners of my mouth twitched, and a cloud of blood mist was swallowed dryly, floating in the dim water, and I stretched out my hand to look at the place just a few meters away, but I couldn't get close to it. The blood oozing from the corners of my eyes blurred my eyes, and my hand finally slowly drooped down, slowly sinking in the direction of darkness......

As if I heard the sound of a water wave in the dark, at the moment of confusion, the corner of my eyes seemed to swing a white flower ocean, the figure floated past me, she was like a goddess in a dream, her right hand pinched the orchid into a finger, and pointed at the brick, the riddle of the riddle......

The next moment! All around is the roar of the cave mountain......
