After experiencing the adventure in Sichuan, climbing is no longer a problem for me. I visually measured the height of the cave, which was more than sixty meters high, about twenty stories high.

Fortunately, it was much easier to walk on this rock, and in less than an hour, I was able to climb very high, and I was most proud that the cigarette from my ears did not fall off the whole time.

I tied a rope with an iron thorn and made a simple safety rope, and by the time I found it difficult to go any further, I was about ten meters away from the top of the cave.

The fat man echoed me below, and I shone my flashlight at the roof of the cave, which was full of stalactites pierced like wolf teeth. As I expected, I found that there was something between these stalactites.

But these stalactites are so big and staggered that I still can't see clearly at this distance.

"Is there anything?" The fat man is looking forward to it very much below, and I said in my heart that if he doesn't climb by his mother, Lao Tzu won't say that he will be angry with you, so he will ignore him.

The fat man screamed persistently below, and I tried to change the angle on the rock, and several times I almost fell, but I still couldn't see clearly.

I took a few breaths, feeling a little depressed, and finally climbed so high, but it was still in vain.

The fat man shouted: "The sunshine incense burner produces purple smoke, and the purple smoke is born in this mountain." It's impossible to see clearly from your position, you shine it on me, the flashlight is at its brightest, I'll take a look. ”

I scolded: "Don't read it if you don't have a culture, if you want to read it, straighten your tongue and then read it?" ”

"Lao Tzu and his mother enliven the atmosphere, you are anxious, don't keep squeezing me, and then I will smoke your sunrise, you may not be a purple smoke." The fat man was furious.

I cursed, so I had to shine my flashlight into the stalactites. As a result, after a long time, he couldn't see any flowers.

But he also saw that there was something in the middle of the stalactites. It's not big, but it must be man-made.

"I can't see it. It's too far away, and the light isn't strong enough. The damn deformity took the telescope away, otherwise it would have been able to see clearly. ”

The core problem is still too far, the tactical distance of the wolf's eye is actually not close, but the human eyesight is limited, and under this kind of gathered light, things are too small, if at the same time they are not something you are familiar with. You see the shape and it's hard to tell what that is.

In this case, either the telescope is expected, or it has to be closer.

When I looked up, it was really difficult to climb and the danger was very high, but at this time, I had decided to take a risk.

I made a gesture to the fat man that I was going to go up, and whether he saw it or not, I continued to look for a place to stay, and went up a few more steps.

I found out. All the way up there were smooth lime waterfalls, and at a reverse angle, I just had to step on them. As long as it takes three seconds, the flesh will lie on the fat man's stomach in a blur.

I don't know how long I struggled in that position, the fat man called me countless times below and I ignored him, I climbed so high, I was unwilling to go down like this.

But there was really no way, and finally the fat man was helpless below, and shouted to me: "Come down, the foreman has promised to give money." ”

Staying in that place, I've run out of energy. I just crawled down and fell all the way to the ground. The fat man shook his head at me.

I clapped my hands and sighed, "I'm completely out of line now." If you have any tricks, go for it. ”

"Fat man, I'm in the morning, I'm out of line, but you're not fruitless, at least there's something on it." He said, "Actually, I have a way that is possible, but I don't dare to say it because it's too risky." You can make a hook with an iron spike and see if you can hook something by throwing it over, swing it over. ”

"Then how am I going to get back?"

"Come back to a fart, you hang on it, and when you find the entrance, I'll go to the building to rescue the little brother and them, and then come to save you." You hang up, smoke a cigarette, and think about the good days ahead of us. ”

The fat man's method is feasible but nonsense, I definitely don't do it, I don't want to say whether the above thing is really related to the entrance, just say that the fat man is really gone, if he also dies in it, then I will hang here and starve to death, this way of dying is too hard.

After climbing again, my physical functions were very exhausted, my fingers were a little shaky, so I moved and went to soak in the water, and at this time, I suddenly realized that my hands did not feel right.

When I shined a flashlight, I noticed that my fingers were dark and my nails were all black.

Dirt? Mud?

But it felt very greasy, not muddy, and when I smelled it, I could smell a strange smell in my nails. Not everyone could smell it, but I knew what was on it.

"Don't look at it, the old ladies are the same, and they are so particular." The fat man scolded.

I said, "No, it's the smell of oil." As he spoke, he looked at the rock walls around him,

"There's fire oil in the cracks of these stones."

I came to the edge of the rock wall, reached in and touched it, it was dry, there was nothing, and then I continued to climb up, all the way to the height of three or four people, I reached into the crack of the stone, and I touched the black oil in my hand.

Fire oil is a special kind of oil, its ingredients are strange, many recipes can be called fire oil, the only common feature is that this oil is a gelatinous, flowing, but very viscous. In the case of a cotton core, it burns very slowly, and it is generally made in a closed place to make a permanent lamp and torch. They will not spoil and will not dry up after sitting for a long time.

The gap was so narrow that my hand couldn't fully penetrate it, but when I shone a flashlight into it, I found that there was a high level of oil in the gap. The dark layer can also be seen with a lot of fist-sized cotton balls inside.

I looked up the gap and saw that the gap filled with fire oil was continuous, spiraling all the way to the top of the cave.

This is a road to ignite the fire, looking at this cotton core, it seems that it is still used for lighting.

The fat man also climbed up, and when he saw it, he was surprised: "Yo ho, there is tahini sauce in it, what is this?" ”

I pointed to the cotton wick and explained to him, and he looked up and said, "Holy shit, this point must be spectacular." ”

"But what is this thing for?" I said, "Do you need so much oil to look in the mirror?" What a extravagance. Moreover, this thing must be disposable, and it is impossible to extinguish these fire oils when they are lit. Even if you have a fire extinguisher, it's not easy for you to climb up and spray it around. At all, the oil had to be burned out. ”

"Not necessarily." The fat man said, he pointed to the cotton wicks in it, "You see these cotton cores, there are traces of burning, these things have been ignited." ”

I shook my head: "I must have ordered it when I tested the quality of the cotton core, and then put it in." If it is lit here, the fire oil here must be burned before it can be extinguished. You climb up against the blazing fire on the wall to extinguish the fire, how many people must die, and all the oil ditches here are connected, and if you want to extinguish it, you must extinguish all the cotton cores at the same time, and if you extinguish only one lamp, the flame on the side will immediately ignite it again. ”

The fat man touched his chin and nodded: "Makes sense." However, this oil ditch and this mirror should be connected here, right? ”

I nodded, and he said, "That's fine." As he spoke, he took out his lighter," said Comrade Marx, saying that practice is the only criterion for testing truth. ”

When I saw it, I was immediately shocked, and I just wanted to ask, "What are you going to do?" ”

The flame of the lighter almost flew out of the fat man's hand, and the fat man poked the lighter into the crack, and the fire oil star in it was ignited at once, and he saw a fire dragon erupt out of the crack in the rock.

Neither he nor I expected the flames to be so fierce, and both of them were caught off guard, and reflexively threw themselves out and fell heavily into the water.

Fortunately, there was water below, and I didn't fall into pain, so I immediately struggled to get up, and when I looked up, I saw a spectacle that made my jaw drop.

I saw a fire dragon spiraling all the way up, as if frightened, crawling on the cave wall, leaving a raging mark of flames. Almost instantly, the entire cave was illuminated by firelight.

At the same time, the temperature in the cave began to rise, and the smell of fire oil immediately filled the entire space.

We watched in amazement as the dragon spread upwards in a circle, almost dizzy.

It took ten minutes for the dragon to reach the top and stop, and we saw a spiral of flames crawling all over the cave wall. The whole cave was fully revealed, and I found that the shape of the cave resembled an inverted trumpet, and all the fire was concentrated in the mirror of the water. The ancient building in the mirror is illuminated as if it were daylight.

"Awesome." The fat man said sluggishly.

I looked back at him and snatched the lighter in his hand: "You insane, what if this oil road is connected to explosives, this place is not as good as before, fat man, can you be reliable and let us live a few more years?" ”

"You shouldn't be here if you want to live a few more years." The fat man said, he didn't look at me at all, but looked at it, "Fat man, I'm not as grinding as you, you see, what is that?" ”

When I looked up, I immediately saw that on the top of the mountain, in the originally dim area, there was a very small model of an ancient building.

A small model of the ancient building, hanging upside down on the roof of the cave. If it weren't for the strong light that eliminated all the shadows, it would have been impossible to see.

"Zhangjia Ancient Building!" I frowned. At the same time, I saw that on the ancient building, there were many flashes of light. It seems that there are many lenses around the model of the ancient building, which are reflecting the light of the fire here. At the same time, I also saw that on the surrounding walls, there were countless points of light faintly flickering, and the whole cave seemed to be glazed.

The fat man muttered, "It turns out that the Zhang family is all from Lilliputian. ”

"No, it's a filter." I said, I looked at the shape of the whole cave, and I immediately understood how it worked, and when I looked at the walls full of flames, I knew that I couldn't verify it. But I'm almost certain that there will never be a second possibility for the secret of the ancient building in the mirror. (To be continued)
