After getting what she wanted, Linlang was not in a hurry to take a serious look at it here. He slipped into his shirt and turned to leave.

It's just that when the corner of his eye inadvertently wiped a book behind him, his footsteps suddenly stopped.

It was a thick book of poems, and a small corner of yellowed paper was exposed under the torn cover, which must have been some years old.

It's just that Linlang pays more attention to the things on it.

- A beautiful black plum......

But the small one is already a little blurry, and it always feels a little familiar. It should be the painter's leisurely drawing while reading a book or doing something.

She tried to carefully open the page, only to find that it was only halfway.

There are traces of burning on it, and a shallow word can be felt on the back of the bookcase - Lu.

There are many people with the surname Lu, but it is estimated that there is only one that can touch the palace library.

That is the Jing'an Hou Mansion.

The unlucky little son who was implicated...... In terms of age, I would be at least fifteen or sixteen years old by now.

Forget it, don't think about it yet.

Stay longer and risk more of being caught.

……

followed the original path and went back, and Linlang returned to the small kitchen smoothly.

The palace maid's residence is a multi-person system, so she is looking for an excuse to go to the small kitchen to develop new dishes, starting from the small kitchen, and naturally returning here.

As a high-quality worker, Linlang used to be like this, and others are used to it, so there is nothing suspicious.

It's late at this point, and there's not much to do.

But Linlang still carefully confirmed that the doors and windows were closed enough, and then sat down in the corner and took out the small note.

This is the physical evidence that dragged the entire Shen family into the water that year.

Linlang raised the fire lamp and looked at it carefully.

It was a piece of waterproof paper with a thick yellow wax coated, and because of time, a few of the glyphs had been scattered a little, but the original appearance could still be seen.

The content is nothing more than the internal secret routes of some northern defenders, and the people of Linlang don't understand these, but they can see the handwriting.

The Shen family is a scholarly family, and Lord Shen, as a master who used to be full of peach and plums all over the world, is naturally a good hand and highly recognizable.

But Linlang didn't believe that if he hadn't done it, how could the exact same words appear in this world inexplicably.

Moreover, this piece of wax paper itself is the biggest problem.

Fish belly books are not uncommon, but most of them use silk yarn brocade, which can also be waterproof.

But the Shen family used wax paper in the case.

After carefully observing and thinking for a long time, Linlang had the courage to gently scrape off the small corner of the piece of paper that was not big in the first place.

Sure enough.

It is two layers, two layers of wax.

Waxing can make the paper transparent, so this first layer is probably for easy copying. What is really used for waterproofing should be the second layer.

The method of first ticking and then filling in is also called Xiangtuo, which is enough to fake the real calligraphy and painting. If the writer has a certain skill, it is even more difficult to see.

But Linlang, as a top calligrapher, and the inspiration brought to her by this piece of wax paper, can still think of this idea.

Sketch the outline of the character first, and then fill in the ink in the middle. It is precisely because of this method of copying and counterfeiting that silk is not chosen, because the outline is drawn on this material first, and the ink is easy to spread.

But I just don't know why, such a thing with key physical evidence was not destroyed, nor was it locked up in the warehouse after the case was concluded.

Instead, it was forgotten in a book, abandoned in the library of the palace for so many years......
