"In addition. Because it is a ciphertext, yin, corresponding to a figure similar to a woman bending her knees to look at the ground, yang corresponds to a figure of a man holding his head up, looking at the sky, a girl is thin, the eldest woman is plump, middle-aged has a crown, and a young man seems to be running for youth. ”

The voice in my head reminds me of these descriptions.

Zhang Yi looked for this box one by one.

In fact.

These lines are very abstract, and even much more abstract than the ancient hieroglyphs. However, although it is abstract, it has its own characteristics, and Zhang Yi can still distinguish them.

Therefore.

Next.

He operated on this Luban lock according to the "password" reminded in his mind.

Yin (female), Dui (girl), Xun (eldest daughter).

Yang (male), Kan (middle male), Gen (young male).

At last.

It's Dikun.

With each step of operation, this Luban lock will change a little. These ciphertexts, densely covering the entire wooden box, are somewhat similar to the dragon seal ghost seal.

Zhang Yi thought when he was operating.

Could it be that the dragon seal ghost seal is also some kind of Luban lock?

Of course, this is just speculation.

The two dragon seal ghost seals, one large and one small, will be fused together for no reason, which illustrates the particularity of the dragon seal ghost seal. Even if it really has some kind of relationship with the Luban lock, it is definitely not this ordinary Luban lock.

Next.

Step by step searching, checking, manipulating, the whole box, has withdrawn a lot of wooden strips.

The last Dikun, the corresponding place, is above that Pagbala temple.

Zhang Yi pressed down.

The stick popped out.

Then, slowly pull it out, and in the process of pulling it out, the remaining wooden strips on the wooden box are all moving.

Some in, some out.

Postures are inconsistent.

By the time Zhang Yi pulled out all the wooden sticks, the entire wooden box had already been opened.

The wooden strips protrude in all directions.

Like a hedgehog.

In the middle of the wooden box, it is only the size of two palms together.

Inside, there is a seal.

At the bottom of the seal is a neatly folded piece of paper. It is estimated that the seal will definitely be able to prove the identity of the owner of this manor, so what kind of content does that paper have?

At this time.

Cheng Xi on the side was already stunned by the process of Zhang Yi untying Luban's lock.

She asked subconsciously.

"You can open such a complicated mechanism, huh?"

Zhang Yi smiled.

"It's okay, I don't think this Luban lock is too difficult, just press it a few times and open it!"

Zhang Yi understated.

At the same time, he had already taken out the seal in the box. However, as soon as the seal was moved, the paper inside suddenly began to change color.

In the beginning.

It is a fair-skinned yellowish color.

But when the seal was removed, the paper had gradually turned yellow-brown, and the color was getting darker and darker.

That rapid oxidative change is visible to the naked eye.

Seemingly.

This nine-turn yin-yang chain lock has a very good seal, and as soon as it is opened, due to its age, oxidation immediately occurs. However, after this oxidation only lasted for a while, it stopped.

It is also not known if it is damaged.

Cheng Xi subconsciously prepared to take the piece of paper and see what was on it.

After all.

It's so well hidden, it must be some kind of classified content.

See here.

Zhang Yi immediately blocked it.

"Wait! Sister Xiaoxi, don't move yet! This thing, paper, is too old, and it suddenly oxidizes, and it may be broken directly when you touch it! ”

Oh.

Cheng Xi retracted his hand.

Holding a seal in one hand.

Zhang Yi approached the paper cautiously with his other hand, and he held his breath.

Paper is indeed brittle when oxidized.

Even though Zhang Yi's hand approached extremely carefully, there were still cracks on it. It seems that, as Zhang Yi thought, the rapid oxidation in a short period of time has almost ruined this piece of paper.

So.

Just this piece of paper, let alone pick it up and look at its contents, I'm afraid that if you move it slightly, it will turn into powder.

"I finally found a clue, but now I can't see it, Zhang Yi, what should I do now? You sell antiques, is there a way to restore this piece of paper? ”

Cheng Xi asked.

Mention of fixes.

Zhang Yi couldn't help but feel a stir in his heart.

"You take this seal first, it's a try!"

Cheng Xi took the seal, looked at it roughly, and muttered.

"Keqin, the helmsman of Tonglu Hall, Zhang Yi, the owner of this manor, is the helmsman of Tonglu Hall, you are so smart, you guessed it, this place really has something to do with Tonglu Hall!"

"But...... What's the word next to this? ”

When Cheng Xi spoke.

Zhang Yi's hand had already lightly touched the piece of paper that had just oxidized rapidly.

He was so careful that he even stopped breathing, and when he couldn't hold it anymore, he would quietly twist his face to the side, take a breath, and then continue.

Followed by.

The voice in my head followed.

"Excuse me, is it an appraisal?"

"Identification!"

In Zhang Yi's heart, he immediately secretly said the word.

"A complete map of the underground secret structure of Keqin Manor at the end of the Qing Dynasty."

Hearing this, Zhang Yi couldn't help but tremble in his heart, he guessed right, this piece of paper is really a very important thing, this is the map of the underground secret passage!

What if the most critical thing is ruined like this?

Without this map, I can't even find the location of the tunnel.

Zhang Yi's heart was in his throat.

In this case.

If you sneeze, the paper will probably be ruined.

Next.

The voice in my head continued.

This picture shows the whole map of the underground secret structure of the Keqin Belle Manor at the end of the Qing Dynasty. Keqin Baylor does not like to compete with the world, good antique calligraphy and painting collection, perennial seclusion here. In the meantime, he built a secret underground structure project, which was another identity for him, he was a member of the Tonglu Hall, and made great contributions to the Tonglu Hall treasure collection project. ”

"This underground secret structure, connected to the old site of Tonglu Hall, and the underground secret warehouse of Tonglu Hall, is one of the core secrets of Tonglu Hall."

"It's a pity that in the process of opening the Luban lock, because of the careless operation and lack of experience, the paper is rapidly oxidized within a short time, resulting in serious damage to the paper, which is like dust and cannot be handled."

"Excuse me, do you want to fix it?"

Listening to that sentence, because of the careless operation, Zhang Yi couldn't help but feel ashamed.

It is estimated that if you hand it over to Uncle Chen to open this Luban lock, there will be no problems.

But.

Fortunately, Cheng Xi mentioned the repair, otherwise, Zhang Yi didn't expect this stubble. Originally, I just gave it a try, but I didn't expect it to be able to fix it.

Therefore, Zhang Yi immediately secretly said the word in his heart.

"Fix!"

In the twinkling of an eye.

The paper didn't seem to have changed much.
