The woman shook her head, "We don't know anything about this place, so we need to start with this place and find out what dynasty and civilization built the ruins of." ”

"And what are you going to do?" Scarface asked, looking at the woman.

"Starting from the statue of the mountain god, their belief in the mountain god is enough to show that they do not belong to the people of the center of the earth, but are an ancient remnant of faith."

Scarface shook his head, "No, the statue isn't just a matter of faith, it's just a matter of fear. ”

"Oh?" The woman raised an eyebrow.

And at this time, my curiosity made me notice a strange phenomenon, that is, when this woman raised her eyebrows, the epidermis on her cheeks did not move. It was only then that I suddenly realized that all the expressions of this woman could not be seen on her face.

Soon a good explanation jumped out, she brought a human skin mask?

I stared at the woman for a moment as her conversation with Scarface continued.

Scarface said, "Remember the altar we came from the drawbridge?" There is a pillar of death that sacrifices the living, and I found a mural over there, which shows ancient people hanging living people on it, and then waiting for the mountain god to come, which is the huge 'snake-like monster' we first saw, so I think that the ancestors who moved here did not simply believe in the 'mountain god', but fear, because they came here so they had to choose to believe in 'it'. ”

"For ...... Why? I hurriedly interjected, because just now the woman suddenly turned her head, and her eyes met me, and I changed the topic with a timidity.

"Stupid, it's because of a clash of beliefs." The woman took over the topic, "Didn't you notice something here all the way?" There are hook-shaped serpentine totems, and there are also mountain god totems, and a remnant tribe will not have two beliefs at the same time, if there are two, it means that it is a last resort. ”

Nodding my head, I suddenly had a feeling of enlightenment, it seems that most of the people here moved in later, so they were forced to worship the huge mountain god, and it is no wonder that there are so many sacrificial stakes on the river beach, because of their mountain god rations.

"It's also forced by life!"

"Let's go up first!" The woman glanced at me, brushed aside the haystack in front of her, and walked forward.

I was looked at in a cold sweat, and I thought to myself, could it be that I found out? No, it's not so easy to spot, maybe it's just because I'm looking at her rudely!

I couldn't care about the superfluous thoughts, so I could only grab my unkempt hair and follow them forward.

Soon we came to the bottom of the huge tower in the center of the square, and the staircase on the right side of the tower was broken by the yew trees, and the snake-like roots clinged to the staircase, shattering most of the staircase.

"Climb up the tree roots, take the stairs where there are stairs, and this place should be able to go up." The woman was a monkey, and she climbed a tree at every turn, but she just glanced up and turned around and said.

"What about this thing?" I kicked the big box with my foot.

"You're watching from below." Scarface said.

After saying that, he and the woman crawled up with their hands and feet.

In a few moments, the two of them disappeared into the upper tower through the leaves, and they were no longer visible.

And I'm bored here, but I started the idea of the wooden box.

It was just a black ordinary box, with metal corners at the corners, and a buckle in front with a padlock on the buckle, which was very common, and I remember when I was in elementary school, many of my classmates used it to lock drawers, and at that time, in order to peek into some of my classmates' little secrets, I specially asked my family to teach me how to open this kind of lock.

The working principle of this lock is very simple, its body has a lock core, in addition to the hole of the key insertion on the lock core, there are several round holes, these few round holes correspond to several round holes on the lock body, and a spring and 2 copper bullets of different heights can be placed inside.

After the key is inserted, due to the different tooth positions, the two marbles are topped to different heights, if the boundary of the two marble in all holes is equal to the circumference of the lock core, the lock core can be rotated in the lock body, so the lock is opened.

Thinking of this, I removed my keyring, and then pulled it straight hard, then folded one end of the 90, and then tripped the keyhole for rotation, and the wire swept back and forth near the pinball in the keyhole, so I tried it hundreds of times, and finally "clicked", and the lock was opened.

When I opened it, I found that the wooden box and notebook were inside, and there was a device inside.

It seemed that this box was originally used for this instrument, so I took out the instrument and looked at it, and soon found the name of the instrument on the nameplate.

"Geological radar sonde?" I muttered.

Isn't that what the geology team uses?

After looking around again, I found that there was a yellow external inspection certificate on the instrument.

This is a certificate that should be on a normal instrument, given by a local metrology institute or a qualified testing agency, and the time when the instrument can be used accurately, but when I saw the calibration time, the whole person was terrified.

Because it reads: "June 15, 2009." ”

Something from '09? Ten years ago?

Something ten years ago, four people, a geological survey team?

At this time, a series of thoughts kept popping up in my mind, as if I was pulling a rope, and I violently brought out everything on the other end.

Boom, as if a thunderbolt exploded in my mind.

Underneath the river slope, a team of 4 people, instruments for surveying and mapping.

Oh my God, is it...... Don't...... Thinking of this, I couldn't help but raise my head and look up, could it be that they were the four people who entered the underground cave and disappeared from the Surveying Institute ten years ago.
