This waterproof bag is very ingeniously designed, and it looks like a high-end product, so I tossed it for a long time to open it and carefully took out the paper inside.

This little pile of paper does not look much, but it has to be unfolded a meter square, and the material used is not clear what it is, but more like a kind of film, thin and tough, with a pale yellow color, and it is full of words, and there is a picture in the center.

I don't know these words, they should be the words of a certain ethnic minority, and the strokes are stereotyped and varied. The map in the middle is extremely detailed, faintly outlining an extraordinary atmosphere between square inches, but I can't see what it is, but I feel that it looks a little like a map.

I have seen some ancient maps, most of them sketch the general terrain, with a variety of very pictographic patterns to mark the terrain features, a mountain is a peak, a water is a lake. I have never seen such a precise map, those fine lines, and regular settings, which make people think of cities or machinery!

Liu Dongxi walked up to me and squatted down, "What is this?" ”

I spread it on the ground and said, "I don't know, I found it on him, I don't know what the ghost drew on it." ”

Liu Dongxi lowered his head and looked at it carefully for a while, and suddenly said, "Dake, you come and take a look!" ”

Wang Dake leaned over and looked at it: "I don't know these things!" Deceptive stuff, right? ”

"This was found from your Professor Feng? Do you think it's going to be a deception? I raised the waterproof bag at her, "Anyway, wasn't this Professor Feng saved by you?" How did you get here? ”

Wang Dake thought for a moment and said: "I don't know, it was very chaotic at the time, and when we were halfway there, people had already started to disappear, and there was no trace left, we all thought that the evil spirits had taken them away, and we agreed not to mention those things!" ”

This explanation was so far-fetched that I asked, "That's it?" ”

"That's it, I don't know how he got here! I was shocked when I saw that it was him just now! ”

"It's a strange material, I don't know what it's made of." Wang Dake said while twisting the piece of paper.

"That's human skin!" Liu Dongxi said coldly, "In the early years, my family got an ancient book from the ancient tomb and said that the abdominal skin of the person who devoured people was taken, supplemented by wormwood ash, and polished with the scalp of the person being eaten, and finally the skin could be wiped into paper, which would not rot or break for ten thousand years, and ten thousand rolls could be taken in." This kind of thing is extremely rare, but I didn't expect to run into it today! ”

Wang Dake immediately threw the paper to the ground, and almost wanted to jump on it and step on it when he saw the disgusted expression. Liu Shifu hurriedly picked it up and said: "This thing is very precious, and the content written on this kind of thing must be extremely important!" Unfortunately, we don't know the words, we can't know what it says. ”

"If you don't know it, put it away first, what's in your backpack?"

"It's just some ordinary equipment, this Professor Feng came here with such a picture, it must have something to do with here, maybe this is my great-grandfather's thing!" Liu Dongxi said.

"Don't care whose it is, it's yours now, if you don't understand it, put it away quickly!" I put that aside and went over to see what they had turned out.

There were already a lot of them on the floor, most of them were food and batteries that we needed very much, a safety box identical to Wang Dake's, a hardcover notebook and two pens. The rest are simple tools, and judging by these things, this guy may really be a professor, not only has a rangefinder and other instruments, but even has a geological hammer in it.

Lu Yan had already divided the battery into several parts, I took one and packed it, and sat aside to look through the notebook. This should be the same thing as a working day journal, and I remember that it is all some running accounts, and the font in it is not as sudden, but has some elegant taste in it.

It can be seen that this Professor Feng is a very rigid and rigorous person, and the account of his daily life and work is very detailed. However, this work diary seems to have just been renewed, and it has been written for more than ten pages. But from these more than ten pages, it can give people a very intuitive impression. Here are some of the more valuable excerpts:

“…… Still can't be deciphered, this kind of text contains more information than I imagined, I tried to use the Tangut language for reference, but found that it was completely incomprehensible......"

“…… It's not a book, it's not a book, it's a document that's completely outside the records of human history, how could there be such a complex text? ……”

“…… Map? No, it's more like a circuit diagram! It couldn't be, I didn't even know what electricity was at that time......

“…… Nothing else, let's go to the place first, maybe this thing has nothing to do with here, my calculation is correct, and their training needs to be more targeted......"

“…… Maybe there can be a new way to ......"

It seems that he only recently got this document, and like us, he has no clue at all. There are all kinds of unreliable speculations behind it, it seems that this old man's ability to think differently is still very strong, and his ideas are quite trendy, and even aliens have thought of it. I continued to look back, only to be caught by a passage. The passage goes like this: "...... I'm going to go in tomorrow, can I see Lu Yuan? Even if it weren't for these decades, I'm afraid he wouldn't know me anymore! Among the three of them back then, why did he get such an ending? ”

I didn't understand this very well, but I understood it almost immediately, this Professor Feng is really Feng Bolin, after Liu Weiming died, the three of them were undoubtedly Zhang Guoqing and the other three people, and it was not only Zhang Guoqing who entered this place back then! Those three people are Zhang Guoqing, Feng Bolin, and one other, undoubtedly Lu Yuan! Feng Bolin was lying in front of my eyes, Zhang Guoqing had become that monster, but I didn't know where this Lu Yuan was sacred.

"I'm going to go in tomorrow" should be talking about the action of entering the sinkhole, so Lu Yuan is in this sinkhole, but how can there be anyone in this sinkhole? How could he know so conclusively that he would definitely be able to meet this person named Lu Yuan? Could it be that this person is on his destination or on his way? According to Wang Dake's description before, their purpose must have been the Danfang under the tree, and there were no living creatures on the way...... Except for the monster at the end, can it be said that ...... That monster is not Zhang Guoqing, but this Lu Yuan?

If that's the case, where did Zhang Guoqing go? I obviously didn't feel that my brain was enough, so I had to close the notebook and hand it to Liu, rubbing my temples and walking out. This Feng Bolin can still participate in such an activity at such an advanced age, it is really old and strong, and it must be of great benefit to have studied this secret so persistently for many years. It seems that the prolongation of life is no longer satisfied, and even the dream of eternal life has come.

I looked at the shadow of the mountain looming in the distance, and my heart was stirred, the events of that year had finally been the most powerful evidence and supplement, although this matter has little to do with us, but I still want to know the truth of the facts. Maybe I thought it was dark before, Feng Bolin may not be for eternal life, but just curious. After all, this curiosity has always been the driving force behind human progress.

I was thinking about it, but I didn't notice that Liu Shiwu was already sitting next to me, "Professor Feng's corpse is a little weird!" ”
