After we ducked into the small door, we were instantly shocked by the wonderful sight in front of us.
This is a huge natural stalactite hall, in the shape of a regular octagon, about three or four stories high. In the middle of the hall, there are rows of stone pillars towering from the sky to the ground, with various murals carved on them.
In the middle of the hall, there are four rows of lotus-seat stone pillars standing in parallel, and each row is composed of six stone pillars placed side by side.
I looked around and found that this was another confined space. Except for the small door we just entered, there was no exit anywhere else.
But suddenly, the small door we had just entered through made a rumbling sound. We turned around suddenly and found that the small door was closed.
At the same time, at the top of the hall, a pair of stone lanterns were lit.
The flame in the stone lantern danced strangely, instantly filling the entire hall with orange light.
Xiangyu leaned towards me with a little fear.
Immediately afterwards, the stone lanterns on the ceiling at the top of the hall clicked one after another, and all of them automatically lit up.
We all immediately looked towards the ceiling——
This kind of scene is more weird than shocking. It gives me the feeling that something terrible will jump out and attack us at any time.
"Look, there seems to be writing on these stone lamps." Zhang Jisheng suddenly said.
I raised my neck, and sure enough, there was a word on each lantern, and together they were:
There is a moon in Chang'an, killing people is invisible. It turns into clouds in the sky, accompanying me full and missing!
"What does this mean?" Xiangyu leaned towards me again.
"There is something strange in this cave. Let's be careful." After Zhang Jisheng finished speaking, he looked at the old man and asked doubtfully: "Old sir, there is no exit here. Why did you bring us here?"
Before Zhang Jisheng finished speaking, a gust of wind came from nowhere and blew the flames in the stone lantern above our heads. Suddenly, a spark of flame floated out from the stone lantern and hit the murals on both sides.
superior.
There was only a "sizzling" sound, and the two murals were ignited. Immediately afterwards, two red lines moved rapidly along the clockwise direction against the wall. In an instant, six murals on the eight walls were ignited!
The hall was instantly surrounded by two semicircular fire rings, trapping us in the middle.
The flames of the stone lanterns on the ceiling of the hall also seemed to get bigger, and bursts of hot air came out, making us choke and cough.
Xiangyu shed tears due to the thick smoke, "I finally know how the female mummies in the rooms on both sides of the corridor in the ancestral hall came from. It turns out that they were baked alive in this way. This is a huge oven."
"Sir, did you bring us here to die?" Zhang Jisheng became angry and asked, glaring at the old man.
The old man's expression seemed to have lost the indifference and indifference it had in the past, but he looked around at a loss, with extreme surprise in his eyes.
The fire got bigger and bigger, and I felt like my throat was about to be corroded, and it became difficult to breathe. And others didn't seem to be any better than me.
In despair, I suddenly noticed that the eight walls and the four rows of six stone pillars in the middle had a particularly familiar feeling.
Xiangyu was still injured and couldn't stand the torment of the thick smoke and heat. She couldn't help but cough violently.
"Let's go back to the stairs first," Zhang Jisheng said.
There was already thick smoke billowing in the hall, and our visual range was extremely low, and we could hardly tell the difference between east, west, north and south.
"The hot smoke is light and floats in the sky. Our cats lowered themselves, covered their noses and slowly found the entrance just now." Zhang Jisheng said, already covering his nose and mouth with his sleeves.
However, when we finally reached the door, the entrance had been closed at some point.
"Xiangyu seems to be about to faint," I supported Xiangyu, who was already weak, and said to the other two people at a loss. I looked at the old man, thinking that in this situation, he would have more solutions.
appearance.
"Calm down, you will get confused if you panic. Let's check first and see if we can open the door from the inside." The old man said, squinting his eyes and scanning the hall. Just as he was about to speak, he coughed violently due to the thick smoke.
He coughed for a while, "This hall seems to be a diagram of Bagua, but I can't see what hexagram is in it. I thought that each of the sixty-four hexagrams of Zhouyi has six lines, but there are only four rows in the hall.
The stone pillar is missing two lines."
If only grandpa were here, he would definitely be able to see something.
Suddenly, an idea flashed into my head. Could these two missing lines be the two unburned walls?
Braving the thick smoke, I ran to the center of the hall, stared at the smoke-filled stone pillars for a while, and finally figured it out.
"Jisheng Xiangyu, I understand, this is a hexagram drawn by Tian Fengji," although accompanied by violent coughing, my voice was full of excitement that could not be expressed in words.
The structure of this hall is the same as the layout of the bookshelves in my grandfather's study.
I hurriedly ran to the third row of stone pillars, and sure enough, I found an abrupt stone pattern on the edge of the stone pillar. I pressed hard, and a secret door appeared.
That night, when I found the hidden compartment on the bookshelf in my grandfather's study, I had always wondered why my grandfather would set the hidden compartment in such a position. Now, I finally know.
Because this position is "Nine Three" in the Tianfengjia hexagram: "The buttocks have no skin, their actions are orderly and severe, and there is no major fault."
