We stood on the stone platform like a living bait, helpless, and countless man-eating leeches swarmed at us from all directions like black waves. The two yellow lines on the bottom of the leech's belly lit up in fright by the gunfire, and the dark cave was full of ghostly yellow light, I wonder if it was a signal that they were ready to attack.

This huge man-eating leech mainly lives in the underground rivers of the tropical rainforest, where there is abundant rain, and there are more mollusks such as plankton and snakes and rats, which provide them with an abundant source of food, but how did they now run into the underground karst cave of Black Tiger Mountain? What do they eat in this dark and cold underground river? Thinking of this, I suddenly remembered what Professor Kang had just said, he said that the wild history records that the Yizhou thorn history is fond of drinking blood, and the habit of the thorn history is exactly the same as the hobby of these cannibal leeches, will there be any connection between the two?

Countless ghostly yellow lines are constantly approaching us, and everyone is terrified and has gone to take weapons to defend themselves. The black bull pulled out the mountaineering pickaxe on his waist, this mountaineering pickaxe is T-shaped, the pickaxe head is sharp, the focus point is clear, it can be used as a close-range combat weapon, if you want to use it to deal with so many leeches, it is obviously not suitable, "Damn, now this thing is better than a broken broom!" With that, the black bull pinned the pickaxe back to the leather on his waist and pulled it with his hand, for fear that it would fall off during the fight if he didn't put it strong for a while. As soon as he lifted his legs, he hooked the Type 79 submachine gun on the ground with his toes, took it in his hand, grabbed his sleeve and wiped the blood on the gun.

I looked around warningly, and hurriedly opened my backpack and found three mountaineering helmets from inside, this kind of Italian-made mountaineering helmet is made of hard material to withstand a lot of impact, and there is a tactical spotlight in front of it, which can last up to 20 hours, especially suitable for use in this dark underground environment. I shouted to Gu Yixin and Hei Niu, threw the two mountaineering helmets to them, picked up the last one and prepared to put it on my head, and suddenly saw Professor Kang next to him, he didn't know when he found a mountaineering stick, holding it in both hands, trembling with fright, I estimate that this seventy-year-old man may have never seen such a terrible situation in his life. The traditional virtue of respecting the old and loving the young in my heart exploded instantly, and I knocked the last mountaineering helmet on his head, and Professor Kang was probably frightened by the so many man-eating leeches in front of him, and he didn't shirk or thank him. The black bull just put on the mountaineering helmet, looked at me, took it off and threw it to me, and said, "You use it, Lao Tzu has thick skin!" "At this time, there is no room for hypocrisy, I didn't shirk anymore, and quickly knocked on my head.

Zhang Xuefeng picked up a black backpack on the ground, took out more than ten boxes of ammunition for submachine guns, quickly put them into his personal satchel, threw the remaining boxes to the two mercenaries, and said in a commanding tone, "No one can shoot without my instructions!" ”

The black-pressed man-eating leeches outflanked us from all sides, and we were so frightened that we didn't dare to come out, and tacitly formed a circle of them, staring around with wide eyes, while at the same time pricking up our ears to listen to the movement on the cliff beneath our feet. Hei Niu asked me while being on guard, "Old Su, weren't you bitten by this thing just now?" I have to share my experience, does it hurt or not? ”

I turned off the wolf-eye flashlight, turned on the tactical spotlight overhead, and replied, "It doesn't hurt, I didn't even feel it at all." This man-eating leech is also a type of leech, and its saliva is said to contain narcotic ingredients that inhibit the defensive response of the attacker. If a leech bites you, you won't be aware unless you see it. ”

Gu Yixin added to me: "The mouthparts on both sides of the leech's body are their mouths, and the inside is like a circular saw. After adsorbing to the skin of the prey, it cuts the skin tissue with its mouth to form a wound, and then uses a strong suction force to suck out the prey's blood. Leeches have more than 300 tiny teeth that can be used to grind through muscles. When they suck blood, their bodies swell and become a sac of blood. Because leeches contain powerful anticoagulants in their saliva, even if they are bitten, they will not only not hurt, but will not bleed. ”

Hei Niu Xiao muttered: "You two sing and act in Huangmei Opera, and you are as comfortable as being massaged by a leech, since it doesn't hurt or itch, you two will be meat shields first." ”

I was just about to answer him, when I suddenly noticed that all the leeches in the cave suddenly stopped, and the sound of chirping disappeared at once, and the yellow lines on the roof and the rock wall flickered twice and gradually darkened, and everyone's nerves collapsed to the limit, and I knew that this calm might indicate a greater crisis.
