The road was dark and long, and the light from the three wolf's eyes was simply 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 shouted as he walked in front: "Old Hu, there is something in front of you blocking the way, throw a cold firework to shine." I pulled out a cold pyrotechnic from my backpack and threw it over, the cold light illuminating what stood in our way. I saw a huge iron frame erected in front of me, and a huge thing hung from it. Before we could see any further, the cold smoke went out. At this time, Shirley Yang suddenly said: "Old Hu, look at the wall. "I looked at the wolf's eye, and I saw a human lamp kneeling on the ground every half a meter by the wall, the same as we saw in the secret room where the kobold statue was placed in the Dust Washing Temple, all naked people kneeling on the ground, with their hands behind their backs, and their mouths wide open. I approached and shone the man's eye on the mouth of the lamp, and as expected, there was some human oil in the mouth, but the wicks in the mouths of the lamps were thicker than those in the chamber, not yet completely rotten, and each wick was connected by ropes.

I took out my lighter and lit a wick, and the flame of this burning wick lit the other wick along the rope, passing one by one, and slowly all the lamps on this side were lit. Shirley Young walked to the other side of the wall and lit the wick, and gradually all the lights were lit, and the cave was bright. We finally saw what we were seeing.

The cave was already at the end of the human lamp, and in front of it was a space that suddenly opened up, as if it was a big hole dug in the mountain, so big that it almost hollowed out the entire mountain. Two meters away from us there was a ditch on the ground, about three meters wide and four or five meters deep, and there was some liquid flowing in the river, which shone in the bright light. In the ravine stood a huge iron shelf, almost reaching the top of the cave. On the top of the iron frame stands a fan-like disc inlaid with seven fan blades, which looks rusty. The diameter of the disc is about three meters, and from a distance, this iron object looks like a monster with a huge head, quietly waiting for the people who come.

The fat man poked me and said, "Old Hu, do you think that iron frame is really a fan for ventilation?" It stands to reason that the DPRK should not have invented the fan yet. ”

Shirley Yang shook his head and said, "I don't know what this iron frame stands in the ditch, but I always feel that there is an inevitable connection between the two." ”

"I think the most serious problem right now is how to cross this ditch." I said to them, "The liquid in this ditch doesn't look like water at all, maybe it's corrosive." ”

"Damn, there's not even a mouse in this broken cave, otherwise you can throw one down and try it." The fat man searched for living creatures to no avail, and said hatefully.

Shirley Yang stood on the edge of the ditch and looked down, turned back to me and said, "Old Hu, this ditch is obviously set up to prevent intruders from entering, but there is an iron frame standing in this ditch, just tie the rope to the top of the iron frame and swing it over." This design is clearly contradictory. Do you think this iron frame is used for some other purpose? ”

The fat man said: "Oh, isn't this obvious, the fan on this iron frame must also be a mechanism, maybe it will turn and hurt people, but hundreds of years have passed, and it has been rusty, I don't believe you see, there is something that can make this big fan spin, and there was no electricity in ancient times." If you want me to say, we'll just hang on that big fan and swing over. ”

I took a closer look at the top of the iron frame, and it was indeed rusty to death, and if there was no external force, it should not turn lightly. And look at this iron frame, it is surrounded by several thigh-thick iron pillars, and there is an iron pipe connected to the fan in the middle, as if there is 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 if nothing else. So I waved my hand: "Cross the river!" ”

Shirley Young used the lassoness skills he had honed in the western United States to put the rope on the fan with ease. The fat man estimated the length, held the end of the rope and said: "Needless to say, it must be my Deputy Commander Wang who took the lead, and he will be the first to wade for his comrades, no matter whether there is a mountain of swords or a sea of fire ahead, I will never flinch!" After saying that, I wanted to grab the rope and swing over. Shirley and I grabbed the fat man and said, "I'll do it first!" ”

I was afraid that the fat man would be reckless and something would happen, so I thought I would go on the road first. Seeing Shirley Yang also say that she would go first, I knew that she was thinking the same way, and I couldn't help but be a little moved. I took Shirley Yang's hand and grabbed the rope and said, "Yang Shen, I know that you in the United States pay attention to women first, but in China, the emphasis is on the big husband charging into battle and the woman sitting in the rear. So you don't fight, I'll go first. "But......" said Shirley Young, and I waved her to prevent her from continuing. I grabbed the rope and waved my hand: "Comrades, rush!" After shouting, he rushed forward desperately.

When I reached the edge of the ditch, I jumped suddenly, thinking that the next second I must have my feet on the ground on the other side of the ditch, but when I was halfway through, the rope sank down suddenly, and the momentum of progress suddenly stopped, and I immediately swung towards the iron frame next to me. The fat man and Shirley Yang behind him exclaimed. Just as I was about to hit the iron frame, I stretched out my leg and kicked on the frame, and my body immediately swung away.

The fat man was about to come up with a rope to save me, but he was stopped by Shirley Yang and said hurriedly: "Don't go up, this iron frame has been rusty for so many years, in case you can't help the weight of the two of you!" When the fat man heard this, he had no choice but to give up, and looked at me anxiously. When I swung back and was about to hit the iron frame, I hooked an iron pillar with my leg, but my leg also hit the iron pillar hard. I grunted in pain. It was too late, and just as my legs were hooking the iron frame, I jerked loose of the rope and clung to an iron pillar with the force of my momentum.
