In view of what Lao Zuo said to me before, now as long as I see things in the Eastern Han Dynasty, I have a strange feeling in my heart.

"At that point in time at the end of the Eastern Han Dynasty, something must have happened......"

Staring at the door on the dirt bag, Lao Zuo's words began to keep recalling in my mind.

Until Lao Zuo asked me: "Can you open it?" I came back to my senses.

He asked if the secret door could be opened.

There is no such thing as a nose or handle on the door panel, and the whole door panel is tightly fastened to the door model, and the door shaft is not even visible at the junction between the door panel and the door frame, so you can't tell whether the door is open inward or outward.

At first, I was still thinking that there might be a more delicate mechanism arranged on this door, so I took out the bell hammer and knocked it a few times, and the sound from the door panel was very muffled, and the bell in the hammer also made a rapid and regular sound, indicating that the white door panel was solid, and there seemed to be no space for placing the mechanism.

Then I took out a very thin knife from the woodworking box and plowed it along the junction between the door panel and the door frame, and I didn't feel any resistance.

It seems that this door panel is actually a cover pressed into the door frame.

This was a bit unexpected, the structure of the secret door was too simple.

But now is not the time to be happy, judging by the sound of the hammer bell just now, it is likely that under this door panel, there is probably a large solid rock formation.

I was about to change tools, and Lao Zuo asked me on the side: "Is there a mechanism in it?" ”

"Don't ask so much." I smiled helplessly.

It is said that Lao Zuo is also a long-famous figure in the industry, why is he always asking this and that like Li Huaishan at the beginning, he keeps thinking about it.

Lao Zuo smiled slightly awkwardly: "I'm just very curious about your craftsmanship." ”

Yes, he was curious, but he wasn't just curious, he was anxious to see my skill at cracking the mechanism, and it seemed that he wanted to steal from me.

I took out two very thin hook knives from the toolbox, first sank the edge of the knife into the gap at the edge of the door panel, and then turned the handle thinner than the needle, and lifted it up with both hand and elbow at the same time.

This door panel weighs fifty or sixty pounds, but fortunately, the two hook knives are made of special steel, and the strength is very high.

With a loud "smack", the door panel was pulled by the hook knife and slipped out of the door frame.

There was something else under the door panel, and as soon as I pulled it up, I saw a relief carved out of the sun carving technique under it.

The main relief is carved on a round stone slab, carved with 36 nameless mountains and 18 landed rivers, the carving is extremely detailed, on the mountainside and belly of some mountains, you can also see clear terraces and square fields, and on the edge of the whole stone slab, there is also a circle of intertwined protrusions, which looks like the thread marks used to connect the cloth when sewing.

Lao Zuo snorted and said, "Why is it the other way around?" ”

I couldn't help but wonder, "What's the other way around?" ”

Lao Zuo said: "In ancient times, people generally believed that the sky was round and the earth was square. But the stone slab engraved with the sun, moon and stars just now is square, but the board engraved with mountains and rivers is round. ”

If he hadn't said it, I really hadn't thought of it for a while.

However, we are not sure whether this is a pure coincidence or deliberate.

Moreover, we don't know if there is such a thing as a round sky in the culture of Heiyi.

Lao Zuo said again: "What do these thread-like reliefs mean?" ”

I picked up the hook knife, knocked on the stone protrusions around the stone slab, shook my head, and said, "This is not a relief, it is a yin and yang line." ”

Lao Zuo didn't understand what the "yin and yang line" was, and his face was a little suspicious, but he didn't ask much.

In fact, if he asked at that time, I must have told him what the yin and yang line was, although these three words are from the "Book of Luban", but they are just a noun, and do not involve the core of Luban's inheritance.

The so-called yin-yang line is actually a kind of staggered line used to fix the mechanism, because the wiring technique is left and right overlapping, up and down staggering, left and right are yin and yang, and the bottom and upper are also yin and yang, so it is called "yin and yang line".

Like most of the organ structures recorded in the Book of Luban, the yin-yang line does not have a particularly fixed situation, as long as it is a structural chain that overlaps left and right, intersects up and down, and reinforces the large organ parts by repeated hooks, it is called the yin-yang line.

For example, the yin and yang lines are made of stones, and the stone teeth are pressed together tightly, staggered and orderly, and they fit so tightly that even the hook knife in my hand can't penetrate it.

Then I took out the bell hammer and struck it several times on the yin-yang line, and the bell sounded very muddy, indicating that there was a more sophisticated mechanism under the yin-yang line made of this stone.

I guess it was some overlapping gears, anchor hooks, and threads.

Before I came, I really didn't expect to encounter such a complex mechanism in this kind of place, but fortunately I have a habit of keeping a toolbox with me, otherwise I would not have been able to handle such a mechanism structure with a pair of hands and a bulky sapper shovel.

I took out a set of smaller hammers and chisels from my toolbox and cut a shallow mark along the curved surface of a stone tooth.

Although these stone teeth look like they are now, I can smell that these stone teeth have a smell of the age of more than ten years ago, and it is estimated that someone has carefully poured stone slurry on them, wrapped the inside of the stone teeth, and later polished the dry slurry to make these stone teeth look so natural.

Sure enough, when a shallow mark was chiseled on the surface of the stone tooth, it was obvious that a metallic luster similar to bronze appeared inside the chisel mark.

However, the sheen is not transparent, with a bit of a rough frosted feeling, and it is clear that the copper elements have been rusted by time before being poured with stone slurry.

From these bronzes, you can smell the smell of the Han Dynasty.

Since they have been wrapped in stone slurry and have not been contaminated by other flavors, the age smell is very pure. I can roughly judge that this thing should have been produced around 180 AD, which is estimated to be only three or four years away from the end of the Eastern Han Dynasty.

At the end of the Eastern Han Dynasty, it refers to the period from 184 to 220 A.D., when the heroes rose together, but Cao Pi had not yet usurped the Han Dynasty.

Thinking of this, I couldn't help but have another thought, this place called Mud Town by the Great Witch of Nojan may also have some kind of inexplicable connection with the old family.

Lao Zuo probably saw that I had been stunned and was a little uneasy, so he raised his hand and patted me on the shoulder: "Why are you stunned?" ”

I tried to stretch my breath, but I couldn't calm down my mood, so I simply didn't care about the state of my mood and asked Lao Zuo directly: "You say, what happened in the last years of the Eastern Han Dynasty?" ”

Lao Zuo is very smart, as soon as I asked, he sensed the problem: "What, this door is something from the Eastern Han Dynasty?" ”

"Well, its production time is only three or four years away from the end of the Eastern Han Dynasty."

"Oh, I can't tell what happened at that point in time, I'll go back to the Soul Village, try to see if I can find the relevant information, you go with me."

I also knew that it wasn't the time to say this now, so I nodded my head quickly, and lay down on the dirt bag, concentrating on the mechanism in the secret door.

When I kept waving the small hammer and chisel in my hand, I removed all the stone shells wrapped in the yin and yang lines, and the stone teeth turned into copper teeth that shimmered blue.

Each copper tooth has a small hole the size of a grain of rice, and the tooth is hollow, through which a relatively small tool can be poked into.

Thanks to a ghost eye, it would have been impossible to see through such a small hole to see the mechanism inside the tooth cavity.

Inside the cavity of the tooth is a seemingly irregular pile of gold threads and anchor hooks, which are the thickness of hair, intricately wound around the tips of the anchor hooks, some of which are linked to each other, and some of which are connected to the bottom of the anchor hooks.

The gears, which were only the size of fingernails, were also made of gold, except that the anchor hooks were not made of metal, but rather carved from the bones of some animal.

I repeatedly observed the intricate structure of the tooth cavity, and found that the gold wire wrapped around the anchor hook was actually only one long wire, and as long as I first removed these gold wires from the tip of the hook, and then removed the anchor hooks that were hooked together, the gear at the bottom of the hook should be able to turn.

This is easier said than done, because every Karakuri element in the cavity is so small that it is necessary to use the finest techniques and tools to untie them one by one, and if you accidentally break the gold thread in the middle of the way, or dial the wrong anchor hook, the door will not be opened.

Why don't I just break it down, you ask?

Indeed, although there may be a metal plate sandwiched inside the stone cover, Liu Shangang has powerful armor-piercing bullets and clay explosives in his hand, and he can also say that he can explode, but I still dare not do it.

Since all the stone shells on the yin and yang lines have been chiseled off by me, a very pure spiritual charm has floated out from the cavity of the copper tooth from time to time, and in terms of strength, it is comparable to the spiritual charm emanating from the entire spiritual street.

I guess that this entrance should have been opened with scriptures or spells, and inside the entrance, there is very likely a very powerful magic circle, and it is tantamount to killing yourself if you break it directly.

Next, I started cracking the mechanism.

I pulled out two tools from my toolbox, a thin, unedged hook knife, and a miniature version of a long-handled gourd hammer with a thin layer of cotton yarn wrapped around the head of the hammer.

First, use the hook knife to gently pull the gold wire away from the anchor hook, and after twitching the hook knife, stuff the gourd hammer the size of an ear picking spoon into the tooth cavity, and carefully remove the anchor hooks that are hooked together.

With only one tooth cavity for the mechanism, the gears are not moving, and all the mechanisms in the copper teeth must be cracked before the gears can move, so I can't tell if there has been a mistake in front until the last set of anchor hooks is opened.
