It was an unbelievable scene, and the beard looked up at the stone wall inserted into the darkness and was amazed: "I heard that blood was spattered three feet, and now it is blood spattered." Pen "Fun" Pavilion www.biquge.info"

I'm not right, this blood was not splashed up, it was obviously someone who was dragged up and flowed all the way down. If you look at this long drag mark, we might as well imagine the recreation of the scene.

Let's say, it was Yu Su's team, there were seven of them, they swam from the underground river upstream, they went ashore here to rest, they made a fire to roast their clothes, and then there was an accident, and someone was injured, and a lot of blood was shed, and they shot something that attacked them, or a person. The wounded man was dragged all the way to the bottom of the stone wall by what attacked them, and then quickly climbed up.

After listening to my speculation, the corners of Abang's mouth couldn't help but tremble again, and he looked around vigilantly, and said in a low voice: "There can't be an invisible monster here, right?" ”

I don't think so, that big monster is so big, if it really tosses around here, it will definitely leave more traces, I guess...... Halfway through the words, I suddenly felt a chill on my forehead, as if the rain was dripping on it, and I said to myself that this is underground, how can it rain? Thinking about it, I wiped my forehead, and when I looked at the back of my hand coldly, my whole body immediately froze, and it turned out to be a drop of blood.

Hu Zi and Abang immediately shone the flashlight upward, but unfortunately we used ordinary waterproof flashlights, the power was too small, the penetration was not enough, and it could only shine out a range of more than ten meters, and it was still pitch black.

But the drop of blood on my forehead shows that there must be something in the darkness that we can't see above.

"Could it be that we're all wrong?" "Let's think about it the other way, what if that person wasn't dragged up, but climbed up on his own to avoid the danger below? After all, it's not realistic for something to drag a big living person to climb such a steep rock wall. ”

At this moment, there was a pop, and something suddenly fell from it, and we looked down and immediately took a breath of cold air, which turned out to be a bloodstained thigh bone that had been gnawed clean.

Hu Zi leaned in and said to Abang: "If that person really climbed up by himself, then is this a distress signal?" Then this guy is really willing to do it. As he spoke, he looked around: "This place should not stay for a long time, flash people." ”

I also think things are too evil, there must be something terrible up there. I remember watching documentaries about big cats, such as cheetahs, and predators that caught their prey and moved it to a higher place to eat. There are certainly no big cats like cheetahs in this underground environment, but we can even encounter invisible big guys, and there is no guarantee that there will be nothing else.

Not daring to think too much, the three of us hurriedly walked downstream along the underground river, looking back as we went, I was afraid that something would follow us.

I'm not sure if there are any Yu Su among the people who started the fire by the river, but it must be someone from their company, as for why they left, and how those blood stains and bullet marks were caused, the reproduction of the scene I just now is just some of my subjective assumptions, and I can only ask them what the real situation is.

The beard walks very fast, and it seems that he is completely hairy, I remember that he has been on the ground a few times, and he has not even been like this when he played with the invisible monster just now, which makes people feel very panicked.

I saw that he reacted so wrongly, and I wondered if it was because he knew what was going on. However, when I asked him, he said that the people in Yu Su's team had guns, and he felt safe with them. I didn't expect him to answer so unreliable.

As we walked, the river narrowed, and the current became more and more turbulent, and there were a large number of rocks on the flat beach, all of which were very large, the largest of which was more than one person high, and we walked around it, and the speed of our march slowed down significantly, and then I heard some small grinding sounds overhead, as if something was crawling on it......
