Dreaming back to the Tang Dynasty, I was working as a detective in Chang'an

I dived into the well again. This time I didn't waste time. I went straight to the bottom of the well and looked at the base under the dragon head carefully, for fear of forgetting any details.

I returned to the well again and copied the base on the ground using branches as I remembered.

The fat man knelt down and watched carefully without saying a word.

"Strange, why is it the Sixteen Ancient Hexagrams of Zhou Tian and not the Eight Trigrams?" He said to himself.

"What is the sixteen hexagrams?"

"This hexagram is divided into the Innate Bagua and the Acquired Bagua. The founder of the Innate Bagua is Fuxi. When this Bagua spread to the Zhou Dynasty, King Wen of Zhou invented the Acquired Bagua based on the number of the nine palaces in the Hetu Luoshu. He combined the Innate Bagua and the Acquired Bagua. After deducing the hexagram numbers of the acquired eight trigrams, we finally deduced the "Sixteen Hexagrams of the Whole Sky" that hides the secret of heaven, which is the sixteen-character ancient hexagram of Zhou Tian. Later, it was thought that the number of hexagrams of the Quan Hexagram was too complete, and it had completely understood the changes in the universe. If you understand the mystery of creation, you will be jealous of ghosts and gods, so you will destroy half of it, which means that after King Wen of Zhou, only gossip has been passed down."

I was confused and said:

"What about the sixteen hexagrams and the eight trigrams?"

The fat man said:

"This shows that this dragon worships Fuxi and has lived for thousands of years."

"How to break this?"

"I only know a little bit about the gossip, but I have never seen any of the sixteen hexagrams in the sky. We can only take risks."

The fat man looked at the pattern on the base carefully again and fell into deep thought.

"Tonight happens to be the night of the full moon. This hexagram will coincide with the pure yin energy of the moon at Zishi. At this time, it will condense into a point. As long as the dragon's mouth of the dragon head is aligned with this point, it should be able to break For this mechanism, we just need to sit here and wait until midnight."

The moonlight was like water. We sat quietly by the well and waited for the moon to gradually climb up. Everyone stopped talking and looked up at the sky. The stars in the sky were blinking. Everyone had something on their mind.

At midnight, we began to stare intently at the sixteen-character hexagram on the ground, motionless for fear of missing something.

It was really magical. Suddenly a beam of light shone down from the sky, began to rotate slowly, and then settled on the word "Kun" in the southeast direction.

This is like a compass, finding the direction for us to open an account.

The fat man said to me:

"Look carefully at this position. After a while, you can go down and twist the dragon head onto the word Kun. Remember not to pause in the middle. If there is a pause, the mechanism will be triggered."

"okay, I get it."

The fat man patted me on the shoulder and said:

"Brother, it's all up to you this time. All you have to do is lure the dragon up. Remember not to get entangled with it."

I re-equipped myself and went down the well.

When I got to the bottom of the well, I took off the well bricks, and then carefully looked at the base under the dragon head, looking for the word Kun in the southeast direction.

The word Kun is on the opposite side of the dragon head. I turned it 180 degrees and felt some inexplicable fear in my heart.

There was no movement at first. Just when I was wondering if I had screwed it wrong, I heard a "click" and the base began to rotate slowly.

After it turned twice, it began to sink one level. It turned out that there was another layer underneath, which happened to merge with the upper layer. At this time, something magical happened.

The base separated to both sides, and the water in the well immediately disappeared without a trace, and a set of stone steps appeared.

I held up the fluorescent crystal tube and began to walk slowly down the stone steps.

The stone steps were not high, and after only walking five or six steps, we reached the level ground. My eyes slowly adapted to the darkness, and following the faint light from the fluorescent crystal tube, I discovered a huge underground cave.

This cave is so big that people can't imagine it. There are stalactites everywhere and the sound of water drops falling.

I held up the fluorescent crystal tube and walked aimlessly in the cave, not knowing where the dragon was hiding.

After walking for a while, I found almost nothing moving. Could it be that there are other mechanisms here?

Tired from walking, I sat on a huge stalactite to take a breather.

At this time, a gust of wind suddenly blew. Although it was very slight, I really felt that there was something behind me!

I broke out in a cold sweat, and when I looked back, I saw a huge dragon looking at me pitifully.

I was so frightened that I stood up immediately and took several steps back.

When did the dragon come? Why is it so mysterious? It's so scary that it comes so suddenly.

"You are really capable, you can actually find the place where I am retreating."

The demonic dragon didn't intend to eat me. It actually observed me with interest, as if it had other things to do than eat me.

"Well, don't you see who our brothers are?"

The dragon laughed and said:

"Did Fatty ask you to find me and lead me to the well so that he can take me in?"

This dragon is really good at pinching and calculating, and is as good as a half-immortal.

"You do not dare?"

"It's not that I don't dare, it's just that I'm not interested." Demonic Dragon said proudly.

"If you don't dare, just say it and no one will laugh at you." I laughed.

"You don't have to use the provocation method to lure me up. I'm very weak now and have no energy. I won't kill you. It's not that I can't kill you, but I can't kill in seclusion, otherwise my power will be broken. You'd better not force me. "

"To put it bluntly, you really have no choice now, so stop pretending to be a big-tailed wolf and follow me up there, otherwise you will die quickly."

The demonic dragon circled around me and said:

"We can keep things separate from each other. Don't mess with my affairs, and I won't cause trouble for you."

I said:

"I just don't understand why you are so stubborn and want to kill the emperor. Wouldn't it be great for you to be a dragon? You are so free, why are you causing trouble for yourself?"

The dragon muttered:

"That was the grievance between the emperor and I in our previous two lives. It took me two lives but I couldn't kill him. I'm not willing to accept it."

"What's the grudge between you?"

The demonic dragon coiled its body and lowered its head. It looked very weak and non-aggressive, which made people feel a little pitiful.
