Through that strange crack, we tried to look across to see where the flies-sized birds had flown to.

But those birds are long gone.

At this time, as if he had thought of something again, the cousin picked up a stone from the ground, probably for safety, to prevent falling into the crack, so the cousin lay down, he climbed twice, close to the end of the stone pillar, and then with the stone in his hand, he began to knock on the stone pillar, and while knocking, he leaned his ear to listen to the sound of the stone pillar, what was he going to do?

After a few taps, he stood up, turned to us and said, "This pillar is empty inside." ”

Everyone was surprised again - what, the stone pillar was hollow?

Hearing what his cousin said, Xiao Lei also picked up a stone, lay on the ground and concocted it in the same way, then stood up and nodded, saying, "My cousin is right, this stone pillar is really hollow." ”

Madman Six asked his cousin in surprise, "How did you guess that this stone pillar is hollow?" ”

This is also what we want to ask, looking at my cousin's series of actions, he should have guessed that the stone pillar is hollow, and then hit it with a stone to verify it.

"Have you noticed, the flying insects, to be precise, the birds, just flew to the hole, the hole where the human skin got into, they should have wanted to get into the hole, but the hole was sealed, and they couldn't get in.

Have you ever wondered, why do they want to go into that hole? I think it's for that skin.

I think that with the size of this bird, they should be parasitic on human skin, because the cells on that human skin have a very fast metabolism, so there should be a lot of 'dead skin', which is what we call 'dander', and that group of birds may feed on dander. ”

Kenya next to her frowned, and couldn't help but say softly: "Oops, this bird is disgusting." Listening to my cousin's words, everyone felt the same way.

The cousin continued: "But I think that there should be a 'symbiotic relationship' between human skin and this group of birds, and the birds eat the dander of human skin, and after the dander is eaten by this bird, it is also very beneficial to human skin, otherwise if the dander is not cleaned up in time, it will stick to the surface of the human skin, and the function of human skin cells will also be affected." ”

"We can understand what you're saying, but how did you guess that this pillar is hollow?" Sister Li asked.

The cousin smiled slightly, pointed to the stone pillar and continued, "This bird is very peculiar, they look for human skin, like a bee finds a flower, and must be very capable in this regard, since they see that the hole is closed, why do they fly to the other side?" The biggest possibility is that the human skin is on the opposite side.

How can human skins go to the other side? You see, from here to the opposite side, how to walk the nearest and most convenient? Of course, it is the pillar of Tongguò, although it is said that human skin can also fly through the wind, but this crack is more than ten meters wide after all, in addition, have you paid attention? Because of the complex terrain here, the air currents are very chaotic, and it is very difficult to drift through with the help of the wind.

Even if the human skin walks along the stone pillar, it is not too easy, because the human skin is very light, so it is easy to be blown away by the turbulent current.

Therefore, the best way for human skin to get to the other side is to go through the stone pillar, and it occurred to me that the stone pillar might be hollow. ”

It turns out that this is the case, my cousin's thinking ability and reasoning ability are really beyond the reach of ordinary people.

At this time, Xiao Lei lay on the edge of the crack and looked under the crack, it was sunny today, but because the crack was twenty or thirty meters deep, it could not completely illuminate the bottom, but unfortunately we didn't bring binoculars, but even if we used the naked eye, we could vaguely see the bottom of the situation.

The bottom seems to be a green meadow, and there are some large boulders, and it looks flat, not unlike the bottom of a normal valley.

"I want to go down and see, at this height, it's still okay to go down with a rope", Xiao Lei took the initiative to mention yì and said, "This crack and stone pillars, I always feel very mysterious, at the bottom of this valley, maybe we will have new discoveries." ”

Everyone knows that with Xiao Lei's skills, it is of course nothing to go down to this valley with a rope, and he can also come up easily, but the valley below this crack is very different from the ordinary valley after all, not to mention anything else, it is the kind of feeling of dizziness when you look down and feel a strong sense of dizziness, which is very unusual.

We've seen a lot of canyons deeper than this, but we've never felt so dizzy, and from that alone, we know that this crack is not very weird, so it should be very dangerous to venture down to the bottom of this crevasse.

Therefore, for Xiao Lei's plan, my cousin, Crazy Six, as well as Old Man Yuan, Mr. Chen, etc., all unanimously expressed their opposition, Old Man Yuan said: "Young man, your courage is commendable, but the bottom of this crack is indeed too weird, you may not know that every time it rains, from this crack, there will be a miserable laughter, so, under this crack, there are too many mysteries, if you don't understand it clearly, it is indeed too dangerous." ”

Xiao Lei saw that everyone didn't agree with him doing that, so he sighed and said: "Actually, I have thought of what everyone said, but I think that so many mysteries are like threads that are mixed together, only one is straightened out, and the others may be solved, so I want to start with this clue and seriously trace it all the way, maybe there will be heavy discoveries." ”

Everyone was silent for the time being, in fact, Xiao Lei's words are also very reasonable, and with his skills and abilities, if he goes down, he will definitely find something, but on the other hand, the bottom of this crack is really too weird.

In the end, it was my cousin who spoke: "In this way, Tian Liwen and Professor Shan may know more secrets than we know about this matter, why don't we go back and ask them?" ”

Everyone thinks that my cousin's method is feasible.

At this time, a thought flashed in my mind, my heart tightened, and I hurriedly said: "It's bad, we all came to chase these 'flying insects', and there was no one left to guard that section of the 'branches', and when we go back, will it be gone?" Because this place is so weird, our clues will always be mysteriously cut off. ”

Mr. Yuan smiled slightly and said: "Well, there is such a possibility, Brother Wang thought of this just now, so let's come over to chase after him, he reminded him a little about this matter, I whistled, let the 'Phoenix Empress' stay by the side, maybe you are all in a hurry to chase and didn't notice this." ”

I see, my cousin is still thoughtful, and there should be no problem with that kind of 'Phoenix Empress' to take care of it.

Everyone looked around the crack for a while, and then returned to Old Man Yuan's courtyard, and sure enough, the 'Phoenix Empress' was standing on a stone not far away, looking at the 'branch' on the ground, there was this kind of bird, and it was estimated that no one could steal it.

In addition, I also slowly realized that the reason why Old Man Yuan didn't let the 'Phoenix Empress' follow him was to let the 'Phoenix Empress' take care of the house, because in Old Man Yuan's home, the value of Xuan Heng's manuscripts on the shelves alone was immeasurable, and if there was a slight mistake, the loss would be too great.

In fact, everyone's next step is to carefully interrogate Tian Liwen and Professor Shan, because judging from what the female translator heard and Tian Liwen's words, the two must have a secret hidden from us, and this secret may be related to that human skin, and for us, it may be extremely important.

When we returned to Mr. Chen's house, we found two Japanese female assistants helping Mr. Chen's wife prepare lunch.

But I didn't see Tian Liwen and Professor Shan, haven't they gotten up yet? No, it's almost noon.

"Professor Shan, what about that Xiao Tian? Haven't they gotten out of bed yet? Mr. Chen asked his wife.

"I woke up early, and the girl told me that they still had some urgent matters to deal with, so they left first, and said that they were very grateful to you for saving Professor Shan", Mr. Chen's wife replied while chopping vegetables.

"What? Let's go? How can you let them go? Chen Lao Xianqing said a little excitedly.

His wife gave him a blank look, but her tone was still very calm: "It's really strange, you didn't let me stop them, besides, people want to leave, can you stop it?" ”

The cousin hurriedly played a round and said: "Ha, yes, what the old sister-in-law said is right, alas, it's actually okay, we used to ask the two of them something, let's go." ”

Mr. Chen's feelings also slowly calmed down, and he knew that he really couldn't complain about his wife.

Old man Ouyang told us that not long after we went out, Professor Shan and Tian Liwen got up, and after a hasty breakfast, they said that they had something to do, so they left.

We were a little disappointed that an important clue was cut off, and the reason why they left so quickly may be because we were afraid that we would get to the bottom of their secrets.

"Don't despair, don't they say in that hotel? Let's go to that hotel and find them directly," Sister Li said.

Xiao Lei shook his head: "I'm afraid it's not easy, Professor Shan was hypnotized in that hotel, so they must be full of fear of that hotel, they won't stay in that hotel for a second, let alone spend the night there, when we go to that hotel to find them, I'm afraid they have already left." ”

After listening to Xiao Lei's analysis, everyone nodded again and again, Xiao Lei is right, this is also human nature, in this way, in this vast mountain, to find two people, is simply looking for a needle in a haystack.

We may never see these two mysterious people, and we will never have a chance to crack the secret hidden in them.

Just when everyone was disappointed and regretful, something unexpected happened--I heard Mr. Chen's wife shouting loudly in the courtyard: "Come on, everyone, that girl is back again, come out and have a look." ”

What, Tian Liwen is back again?!

Xiao Lei was the first to run out, and we followed closely to the courtyard, at this time, I saw Tian Liwen sitting on the stone in the courtyard, panting heavily, her pants and shirt were scratched, and there were several abrasions on her face, and her face was frightened, and she looked extremely excited.

What's going on?
