But soon I knew another role of Lu Xiaodan.

At this point, she came directly to the monster, and then reached out and pressed the monster's stomach lightly.

I watched her keep touching the inside, and after a long time, she said: "There is a mechanism in the stomach, it looks like a crossbow sword, and there is a box-like thing, maybe ***." ”

Damn, you can feel it? I looked at the monster, and there were indeed some seams in his belly.

It seems that it really can't be easily moved.

And I looked around carefully, and sure enough, under the monster's tail, I could see something like a shiny jade plate.

This thing looks very valuable, but putting it here reminds me of the ice jade on the top of the green corpse's head.

This thing is a mechanism, not for taking away at all, I think it should be turned, but once it is turned, I don't know what kind of effect it will have.

Lu Xiaodan had already touched it at this time, and then snorted coldly and said, "There is still liquid in the body, I'm afraid it's oil, if you're not careful, you may touch something like flames." ”

"I'll go, such a cow?" A man who came with us said.

Lu Xiaodan nodded and said: "This is the living corpse mechanism, this monster outside should have been a living creature before, it's really strange, what kind of animal is this, why can't you see it now." ”

"It's normal." I had no choice but to say, "In the current world, it can be said that there are many extinct animals, whether they are man-made or naturally formed, so it is normal for this animal to not see it now." ”

Lu Xiaodan nodded, but immediately said, "Then Brother Wen, have you found the mechanism?" ”

"I found it, but I can't turn it yet, let's go back first and ask about the situation over there."

Our team went back through the passage to the edge of the stone wall.

This stone wall is really well built, it is seamless, and there is no translucent place at all.

Fortunately, the stone walls are relatively thin in some places.

As we got here, we heard a few tapping sounds.

It seems that Brother Long and the others have also opened the door and asked us about the situation here.

Brother Tiger took out a sapper shovel from his backpack, and then tapped it on the stone wall a few times with the side of the hammer.

Immediately there was a knocking sound over there.

I don't know what they call this kind of password, anyway, people can communicate that.

"Say what?" Brother Tiger looked at me and asked.

"Tell them about the situation, and tell them not to stand in front of the agency."

Brother Tiger immediately tapped on it, and then listened to the sound on the other side.

After a while, there was a knocking sound on the other side.

"Understood, he asked us, how are we going to operate this mechanism?"

I thought about it for a while, and it is said that such a mechanism must be screwed, but it is screwed in this direction, but it is exquisite.

You know, we are now in two completely opposite rooms, that is, we should turn the wheel in opposite directions.

In this way, it conforms to the principle of the reversal of yin and yang of these things.

After talking to Brother Long over there, Brother Long quickly responded: "The key is how many turns?" ”

I was stunned for a moment, a few laps, I really didn't think about this.

That turntable is not like the current water screwing valve, it has a certain number of turns, and when it turns to a certain point, it stops.

It should be able to rotate indefinitely, but with a few turns, it's a headache.

If we go to a lap that doesn't correspond, then there will be a problem, right?

Wait a minute, nine layers and eight formations, I thought about it carefully, and suddenly realized that this is a mechanism set for us by the ancients.

"How long have we been down?" I glanced at Brother Tiger.

Brother Hu immediately looked at his watch and said, "Twenty-six minutes." ”

"No, I mean, how long have we been down since we opened it forty-eight hours?"

Brother Tiger sighed, looked at it a few times, and said, "It's not long, it's only six hours, that is, there are forty-two hours." ”

I see.

I smiled slightly, what a powerful mechanism, if I hadn't just thought of the words written by my father in the I Ching, we would have died here.

I remember when I first read it, it said that there were nine layers and eight formations, and the eight formations were the same as the outer formations, each formation decreased, and finally when the door was closed.

At the time, I didn't know what it meant, but now I understand it all.

This is too damn and designed too ruthlessly, right?

Forty-eight hours outside is also a limit here.

In this way, the time limit of the array outside should correspond to this place, and there must be some connection between them.

This connected place neatly controls the time limit of the entire mechanism.

If we do it wrong, then if the internal and external time is not synchronized, it is very likely that we will be stuck here.

"What the hell is going on? Brother Wen, do you have a suggestion? Lu Xiaodan asked anxiously.

I nodded and asked Brother Tiger for the exact time.

Brother Hu thought about it carefully and said, "Six hours and twenty-seven minutes." ”

How can this minute correspond? My head hurts a little.

But I quickly found a way.

I asked Brother Tiger to knock on that side first, saying don't worry, we still have about half an hour to continue up, let them pay attention.

Then I asked Lu Xiaodan for a piece of paper and pen to calculate.

It should be said that the ancients designed this thing not only to be accurate to the hour, that would be really troublesome.

But if it's accurate to the score, they don't have the ability to do it.

So I think they probably counted by the moment, because in ancient times there was often such a thing as a moment and a moment.

For example, three o'clock in the afternoon, it is a good time for decapitation.

I don't know what the scientific basis is.

If we do this calculation, then we are now facing such a situation.

If it's by the quarter, I'm not very good at corresponding, and this number, if it's placed in the dial, looks at the minute hand or corresponds very well.

But the disc obviously has no minute hand, it can only be the hour hand, so it requires a rather delicate operation when it comes to the quarter.

I calculated that it would take 12 hours for the disc to rotate once, and if we rotated it on the spot, it would be simpler.

For example, in another thirty minutes, it will be seven hours.

In other words, there are forty-one hours left, and three revolutions are thirty-six hours, which means that there are still five hours to turn.

And five hours, just thirty degrees less than one hundred and eighty degrees, is just right.

I think it's possible to measure this angle, and we don't need it to be completely tight.

At this point, I breathed a sigh of relief.

"Brother Wen, how's it going?" Probably seeing that my expression relaxed, Lu Xiaodan immediately walked over and asked.

I asked a few people to come closer, and then it was mainly Brother Tiger, and I showed him the picture I had drawn on paper.

Brother Hu looked at it for a long time and said, "These two, one is in the direction of six o'clock, and the other is in the direction of five o'clock." ”

"Great, it's best if you have that kind of statement." I clapped my hands, and the word was professional, "The agreed time is seven hours before we come down, what time is it?" ”

Brother Hu looked at his watch and said, "Five forty o'clock." ”

"Okay, let's start at 5:40, so make a mark on the disc and the stone below the disk, and the dots on the disc correspond to the six o'clock direction below, and then make a mark in the direction of five o'clock."

Brother Tiger frowned and said, "This is very difficult to post, you must know that our secret language is unlikely to be so detailed." ”

I scratched my head, thought for a moment, and said; "Don't worry, you listen to it first, and then see how to pass it on to him."

Then I drew a picture on the paper so that Brother Tiger could understand it a little bit.

Actually, the reason is very simple.

Draw a dot on that disc, this thing is equivalent to making a mark on the disc, and this dot can be drawn anywhere.

Correspondingly, on the stone platform below this point, make a mark of six o'clock, and then deviate from the angle of thirty degrees to make a mark of five o'clock, which is to mark the beginning and the end.

Then, when we turn the disc, we have to turn it three times and five hours, that is, the mark on the disc crosses the origin of the starting point at six o'clock three times, and then turns to the dot in the direction of five o'clock.

After talking to Brother Hu twice, he finally understood, then thought for a while and said, "I can pass it on, don't worry." ”

I nodded, and let him tap it.

Brother Hu finished it quickly, then smiled and said, "Got it, they will start at 5:40, we just got the table right, there will be no problem." ”

That's for the best.

Of course, we had to get ready, and we got into the room, and we all went around behind the monster, and then Tiger took out an oil-based pen and made a mark on the disc.

I watched him operate for a while, and didn't remind him, to make sure he really understood what I meant, and passed it on to Brother Long.

Thankfully, he's done a pretty good job.

I breathed a sigh of relief, stretched and said, "Great, this way, we will definitely be able to go up, and it will only take eight hours, so that it won't be long before we reach the top." ”

"That's for the best." Lu Xiaodan said with a smile: "But there is a question I want to ask you, Brother Wen, that is, if we go up, do we take one line or two." ”

"Two of them, two symmetrical ones, so that we can continue to enter the eight formations in different positions, which is right, I believe it is going up."

I responded with a smile, but when I finished responding, I immediately felt that something was wrong, did I forget something just now, damn, I really forgot.
