The road was dark and long, and the light from the three wolf eyes was not enough to illuminate the entire road.
After walking for about ten minutes, there was a crunching sound in front of me.
The fat man walked in front and shouted: "Old Hu, there is something blocking the road ahead, throw a cold firework to shine."
I took out a cold firework from my backpack and threw it over, and the cold firelight illuminated the front of us.
Something in the way.
I saw a huge iron frame standing in front of me, with a huge thing hanging on it.
Before we could get a closer look, the cold smoke went out.
At this time, Shiry Yang suddenly said: "Old Hu, look at the wall."
I looked over with wolf eyes, and saw a man kneeling on the ground every half meter beside the wall, placing a dog-headed figure with us in Xichen Temple.
Just like what I saw in the secret room, they were all naked people kneeling on the ground, with their hands behind their backs and their mouths wide open.
I walked closer and looked at the mouth of the human lamp with my wolf eyes.
As expected, there was some human oil in the mouth, but the wicks in the mouths of these human lamps were thicker than those in the secret room and were not completely rotten.
They are all connected with ropes.
I took out a lighter and lit one wick.
The flame of this burning wick lit another wick along the rope, passing one to another, and slowly all the lamps on this side were lit.
Shiry Yang walked to the other side of the wall and lit the wicks.
Gradually, all the lamps were lit, and the cave became bright.
We finally saw what was before us.
The cave has already ended at Rendeng.
In front of it is a suddenly open space, which seems to be a big hole dug into the mountain, so big that it almost hollows out the entire mountain.
There is a ditch on the ground two meters away from us, about three meters wide and four to five meters deep.
There is some liquid flowing in the river, which glows flickeringly under the bright light.
A huge iron frame stood in the ditch, almost reaching the top of the cave.
On the upper part of the iron frame stands a fan-like disk, inlaid with seven fan blades, which looks rusty.
The diameter of the disk is about three meters.
From a distance, this iron tool looks like a monster with a huge head, quietly waiting for people to come.
The fat man poked me and said, "Old Hu, do you think that iron frame is really a ventilation fan?
It stands to reason that the fan has not been invented yet."
Shiry Yang shook his head and said, "I don't know what the meaning of this iron frame standing in the ditch is.
I always feel that there is an inevitable connection between the two."
"I think the most serious problem now is how to cross this ditch."
I said to them.
"The liquid in this ditch doesn't look like water at all.
It may be corrosive in some way."
"Damn it, there aren't even mice in this broken cave, otherwise we could throw one in and try."
The fat man looked for any living things to no avail and said bitterly.
Shiry Yang stood on the edge of the ditch and looked down.
He turned around and said to me: "Old Hu, the ditch is obviously set up to prevent intruders from entering, but there is an iron frame in the ditch.
As long as the rope is tied Just swing over the top of the iron frame.
This design is obviously contradictory.
Do you think this iron frame has any other purpose?"
The fat man said: "Oh, isn't it obvious?
The fan on the iron frame must be a mechanism, and it might hurt people when it spins.
But hundreds of years have passed and it's already fucking rusty.
If you don't believe me, look at this.

Is there anything that can make this big fan spin?
In the old days, there was no electricity.
We could just hang on that big fan."
I took a closer look at the top of the iron frame, and it was indeed very rusty.
It should not be able to rotate easily without external force.
And looking at this iron frame, it is built around several thigh-thick iron pillars.
There is an iron pipe in the middle connected to the fan, which seems to have a bearing or something.
The most important thing is that these iron pillars, iron pipes, and bearings are all rusted to death, and they should not move unless something unexpected happens.
So I waved my hand: "Cross the river" Shiry Yang used the horse roping skills he had learned in the American West to easily put the rope on the fan.
The fat man estimated the length, held the end of the rope and said: "Needless to say, I, the deputy commander, must be the one who takes the lead and leads the way for the comrades.
No matter whether there is a mountain of knives or a sea of fire ahead, I will never back down."
After saying this, he thought Grab the rope and swing over.
Shiry Yang and I grabbed the fat man and said at the same time: "I'll come first."
I was afraid that the fat man would be reckless and something unexpected would happen, so I thought I would go on a journey first.
Seeing Shiry Yang also said to go there first, I knew she thought so too, and I couldn't help but feel a little moved.
I took off Shiry Yang's hand that was holding the rope and said, "Yang Shen, I know that in the United States, you emphasize that ladies come first, but in China, it's important that men go to the front and women sit in the rear.
So don't argue, I'll go first."
"But" Shiry Yang wanted to say something else, but I waved my hand to stop her from continuing.
I grabbed the rope, waved my hand and said, "Comrades, rush."
After shouting, I rushed forward with all my strength.
When I reached the edge of the river ditch, I jumped suddenly.
I thought for a second that my feet must be stepping on the land on the other side of the river ditch.
Unexpectedly, when I was halfway through the swing, the rope suddenly sank, and my forward momentum suddenly stopped.
He immediately swung towards the iron shelf next to him.
The fat man and Shiry Yang behind him exclaimed.
Just when I was about to hit the iron frame, I stretched my legs and kicked on the iron frame, and my body immediately swayed away.
The fat man immediately wanted to come up with a rope to rescue me, but Shiry Yang stopped me and said anxiously: "You must not go up there.
This iron frame has been rusted for so many years.
What if it can't bear the weight of you two?"
The fat man had to give up after hearing this. , looked at me anxiously.
When I swung back and was about to hit the iron frame, I hooked my leg on an iron pillar, but my leg also hit the iron pillar hard.
I groaned in pain.
Soon enough, just when my legs were hooked on the iron frame, I suddenly let go of the rope and used the momentum to hug an iron pillar tightly
