Looking back, it was Grandma Li. Pen | fun | pavilion www. ｂｉｑｕｇｅ。 ｉｎｆｏ

I saw the face inside the glass cover wink at me, like a naughty little girl, and then swam to the side. I smiled bitterly and hurriedly followed, trying my best to keep a distance of less than two meters from her, because the water was too muddy, and it was difficult to see at a distance, for fear of losing it.

Strange to say, the river that stretches beyond the cave looks very clear, but why is this skylight lake so muddy?

The second grandmother said that there are a total of seven skylights in this area, which are distributed in the Big Dipper, of which the passage between the first two is on the surface, and the passage between the back five is in the underwater cave. After reaching the last skylight, there is a cave about 10 meters underwater, from which there is access to a dry underground cave, where the Suolong Well is located.

Since the water under the skylight may almost never be explored, the road ahead is fraught with positional hazards. In order to be able to return the same way when we encountered danger, we laid navigation lines along the way, but we didn't expect the water to be muddy, and many times we couldn't see where those lines were.

Of all the expeditions, the underwater cave exploration was the most dangerous and the most strenuous of all, and it took us nearly an hour to move forward for about 100 meters, and it was clear that the water was flowing slowly and rapidly along the way.

The cave was very spacious, and after swimming more than fifty meters in zigzags, a bright light faintly appeared on the top. We turned on the flashlight and shone it on the lake, but we couldn't see it because of the turbidity of the water.

Rising to the surface, a third skylight lake appeared in front of us, and a ray of sunlight poured down from the skylight, shining warmly on us.

I gestured to my second grandmother and asked how she was doing and if she wanted to take a break. She gestured to me to indicate that she was currently full of energy, and asked me to continue with her to find the next skylight. I admired the old lady and threw myself to the ground, and when I got to her current age, I was afraid that it would be difficult to even play LOL.

Just as I was about to go underwater to find a new hole, I suddenly caught a glimpse of a black shadow more than ten meters below the water on the right.

I hurriedly took out the dagger I had with me and stared at it aggressively.

This skylight is full of lakes, and there is no land to settle on, and if that guy is the legendary man-eating monster, it will be bad for David.

When the second grandmother saw me like this, she swam over and asked what was going on?

I pointed my finger there, and Grandma Li couldn't help but change her face when she looked at it.

But she quickly regained her composure and took off her helmet, as did I. After taking a big breath of fresh air, she whispered to me, "This cave has existed tens of millions of years ago, and it's not uncommon for a cave creature to exist. My master has been here several times, but he has never said that he has encountered any monsters that can attack people, and I have also been here, but I have never encountered them. We look for the hole on our own, and don't make any extraneous branches. ”

I nodded, put my helmet back on with her, and dived back into the water. Although the black shadow kept a distance of more than ten meters from us from beginning to end, I always felt hairy in my heart.

After diving about twenty meters, a narrow hole appeared in front of me, and its diameter reminded me of the black shadow just now. However, judging by the speed of the current, a huge underground river was deeper below, and we gritted our teeth, not caring if there would be danger, and swam into the hole.

The water is getting muddy, which seriously affects our speed, and new problems are emerging one after another. After thousands of years of water erosion, much of the sediment has fallen on the walls of the surrounding caves. We were very careful about our kicking of the water, trying to keep our distance from the cave wall and not touching the surface of the stones, so that the water would not become more muddy. However, the water is coming up from below, mixed with many bubbles, and as it rises, it will rub off a lot of sediment, making the visibility of the water deteriorate faster. In the end, I couldn't see the second grandmother next to me clearly, only vaguely saw a petite figure, and in desperation, I had to hold the navigation line next to me and move forward with difficulty. However, what worries me more than the above is that the speed of travel is so slow, and if the oxygen cylinders run out, the consequences will be unimaginable.

At that moment, the dark shadow reappeared. This guy has been following us, not attacking, not approaching us, I don't know what the hell is going on. Diving in an underwater cave is just that, on the one hand, to overcome the difficulties posed by the water pressure, and on the other hand, to overcome the fear of the unknown that may arise.

By the time we reached the seventh skylight, the oxygen cylinder was more than half used and it was impossible to return the way it came. However, the second grandmother said that after she arrived at Suolongjing, she did not return from the original waterway, but took another dry road and went up to the surface.

I looked around, and it was not much different from the previous skylights, and even the lake was nearly half the size of the lake, and there was no shadow of the wellhead at all.

Everyone took off their helmets and looked around in a daze.

I asked, "Second grandmother, this is the seventh cave, right?" Why don't you see the well? ”

The second grandmother said blankly: "I don't know why, in the past few decades, the cave has changed too much. As the water level rises, maybe the well has fallen below the water's surface? ”

I shook my head and said, "I have carefully searched when I dived just now, and the underwater terrain in this area is very undulating, and the drop is very large, and it is unlikely that a well will be built. And all the way around, I didn't see a well there. ”

"However, the route on the Long Yuan Sword is like this, it's right." The second grandmother muttered to herself, and after a while, she slapped her thigh and said in a low voice: "The Big Dipper is nine stars, seven appear and two are hidden, the eighth star is called Bixing, on the right of the seventh star, not seen, the ninth star is called the auxiliary star, and on the left of the sixth star, it is common." ”

I asked, "Second grandmother, what kind of mantra are you chanting?" ”

The second grandmother said: "This is not a spell, it is a passage from the Song Dynasty Astronomical Chronicles." It is said that the Beidou is not seven stars, but has nine stars. The eighth was called the Bird Star, and to the right of the seventh, it was no longer visible to the naked eye at that time. The ninth is called a secondary star, to the left of the sixth, and is sometimes visible to the naked eye. Since this is distributed according to the Big Dipper, could there also be nine skylights, not seven as we think? ”

I was excited and said, "It's possible!" Let's dive down and take a closer look, and maybe we'll find a new hole. ”

Sure enough, more than thirty meters below the stone wall on the east side, there was a narrow cave.

Just as we were about to get in, the black shadow that had been following us in the distance suddenly swam towards us! (To be continued.) )
