Gao Moli stood up and looked up, as if he had a premonition of the great changes that were about to come in this underground cave, and he told me to follow him closely. I didn't know why, and was about to ask him when I suddenly heard the sound of water in the hole above my head stop. The sound of the water is the only sound except for our screams and the slight rustling, and it is also the loudest sound in this cave, from the moment we entered, everyone has been used to it, and now it suddenly disappears, everyone can't help but be stunned, thinking about it, the water in the black pool has completely flowed. At the top of the cave, there is a nearly circular hole with a diameter of more than ten meters, which is like a living door for us who are hanging by a thread, hanging high in a place that is difficult to reach. At this time, the moon has been tilted to the west, and the cool moonlight shines obliquely through the cave entrance above the cave, forming a huge circular spot of light on the rock wall on the side of the stone platform, which is clear and bright, giving people the illusion that the moon is embedded in the rock wall.

The man-eating leeches shrouded in the shadow of the moon suddenly stopped wriggling, stood still for a while, and quickly turned around and fled. The leeches around Moon Shadow also began to agitate, and this restlessness soon formed a chain reaction, and the leeches on the entire rock wall fled for their lives as if they were facing a great enemy, retreating at great speed to the top of the cave far away from the stone wall. The leeches on the stone platform where we were also retreated, crackling and falling into the river.

"What the is going on? Could it be that cannibal leeches are afraid of moonshine like vampires? No, vampires seem to be afraid of sunlight and like moonlight. The black bull said as he pulled off the man-eating leech that was tightly attached to his leg like a cucumber. I've just learned how powerful these man-eating leeches are, they can probe their mouthparts under human skin through their trouser legs, and thus suck human blood. If the black bull wasn't wide and fat, the leeches on his legs were enough to cause him to lose too much blood.

"I don't think it's a matter of light, the tactical spotlights above our heads are stronger than the moonlight, and they're not afraid at all." With that, I looked up, and at the same time I felt a strong air flow rushing in from the hole overhead, and this air flow gradually strengthened, and soon formed a strong gust of wind in the cave, which made it a little difficult for people to stand, I grabbed a blown tumbling military kettle on the ground, and said, "Don't doubt it, it must be the wind that blew those man-eating leeches away." ”

Gu Yixin picked up the panting Professor Kang, walked up to me and said, "I don't think this theory is quite valid, there was no such strong wind just now, and there is a layer of mucus on the body surface of the leech, and the adsorption capacity is very strong, such a wind cannot pose a threat to them at all, I think they may have a premonition of some kind of impending danger, and this danger may be fatal to them." ”

Gu Yixin's explanation is not unreasonable, the ability to predict danger is common in the animal kingdom, many animals have special senses in certain organs, they can know the occurrence of some disaster events in advance of humans, such as jellyfish in the ocean can predict storms, rats can avoid mine collapses or harmful gases in advance. One of the most common is the premonition of the animal on the earthquake, the underground fault plane will produce a low-frequency sound wave before the earthquake, this kind of sound wave people can not perceive, but those animals who feel very sensitive, when they feel this sound wave, they will be frightened, so that there are abnormal phenomena such as winter snakes out of holes, fish jumping on the water, pigs and cows jumping circles, dogs crying and wolf roaring. The sudden retreat of man-eating leeches is also an anomaly, and they may really have a premonition of some kind of danger approaching, which may be due to the special nature of the organs, or it may come from their accumulated survival experience.

Gao Moli didn't pay attention to our analysis, walked straight to the stone wall, stretched out his hand to touch the moonlight on the stone wall, his expression was still as calm as ever, but there was a faint trace of eager expectation in his eyes, as if he was expecting something to happen. I was about to walk to the edge of the rock wall, but my legs were grabbed by the old smoking gun wailing, "Help me!" Little gentleman, help me! ”

I was startled, and quickly looked down at him, only to see the old cigarette gun sitting on the ground, wailing in pain, the broken jade cigarette stick fell to the ground, and the other section was still tightly grasped in his hand, he curled up on one leg, one leg was spread on the ground, and something seemed to be squirming under the flat trouser leg, and the old cigarette gun hit the trouser leg with the half of the jade cigarette stick in his hand, and wailed in his mouth, "It hurts me!" Help me! I secretly said no, quickly squatted down to pull his trouser leg, only to see a white bone stubble exposed, the calf bone has no trace of flesh and blood, dozens of cannibal leeches densely bitten on his kneecap, in the blink of an eye, the flesh on his kneecap also disappeared, the old smoking gun looked down, frightened screamed and fainted. It seems that the leeches here have indeed mutated, not only sucking human blood, but also eating human muscles, and the gnawing speed is quite fast, it is no wonder that the glasses team doctor instantly turned into a pair of skins.

I beckoned Hei Niu and Gu Yixin to come over, put the paratrooper knife in the only remaining charcoal fire in the smokeless stove and roasted it red, aimed it at the knee of the old smoking gun, and scalded the leeches off one by one. Gu Yixin sprinkled some medicinal powder on the knee of the old smoking gun, and then tied his thigh with a bandage to prevent excessive bleeding and bacterial infection. After some tossing and turning, the three of them finally disposed of the stump of the old smoking gun, and just as I was about to stand up, I felt a tremor under my feet.

The black bull looked at me with wide eyes and asked with a puzzled face, "Damn, this is going to be an earthquake?" I looked around vigilantly and replied, "It seems to be, it doesn't seem to be, I've experienced earthquakes, earthquakes have explosive qualities, and they don't tremble like this all the time, and it feels like the cave has been adjusted to vibrate mode." ”

"Look at the river!" Gu Yixin shouted, and everyone's eyes were on the underground river, only to see that the water in the underground river suddenly rose up at some point, and there was only two or three meters away from the stone platform, and the black shadow under the river was rolling, like a demon ready to break through the water at any time.

Suddenly, there was a rumbling overhead, the moon shadow on the rock wall disappeared all at once, and the hole at the bottom of the waterhole and the cave was sealed by a huge rock that collapsed on the surface, and the cave became a claustrophobic space completely isolated from the outside world.

There is a very narrow gap between the stone wall and the stone platform where we are, the stone wall moves up, forming a natural press, countless man-eating leeches are continuously brought into the gap, and the man-eating leeches in the gap are rubbed and squeezed by the boulders on both sides, and in an instant, the blood plasma is splashed, and the stone wall, the stone platform, and the river are full of blood. The dark shadows in the underground river seemed to be awakened, churning like boiling water, and all the man-eating leeches opened their mouthparts on both sides of their bodies, greedily sucking the scarlet river water. The scene in front of me was like a grand blood sacrifice ceremony.
