Dian Hua put down the bamboo slips in his hand and looked at the bookshelf, there was a wooden board engraved with a big "history" on the side wall of the bookshelf, and under each grid on the bookshelf was a wooden plaque engraved with the key information of the bamboo slips stored inside.

For example, the bamboo slips just now are stored in the "Jishui County" section of the "History" bookshelf.

Who said that the books of the ancients were stored indiscriminately without logic? Aren't they very logical? It's similar to the libraries of the modern world?

Discovering this pattern, Dian Hua began to look at the names of these bookshelves and the partitions above them, and there was a large frame, so that he knew it by heart.

Dianhua found a bookshelf of several types of books he was looking for. There are bookshelves with the word "Wu" that store the secrets of martial arts, bookshelves with the word "Di" that store books related to geography, and bookshelves with the word "miscellaneous" that store fortune telling in feng shui, etc.

With a rough outline, Dianhua began to search for relevant books in the planned order.

"The first thing I chose was the martial arts cheats. ”

Dianhua walked to the front of the Wuzi bookshelf.

"According to the habit, first read the history of the evolution of martial arts, theories related, and books related to the evaluation of martial arts cheats, so that you know what to do, and then choose specific martial arts cheats. ”

I knew it, I didn't panic in my hand, I made a decisive choice, and I soon found the book I wanted to read.

"Theory of Martial Arts", by Qi Hong, The Evolution of Martial Arts. ”

Dian Hua found that the books on theoretical research in the Qi Mansion Library were all surnamed Qi, and they should all be members of the Jishui Qi clan. Considering that this is an era in which books are recorded in the form of bamboo slips, the emergence of this phenomenon of family learning is quite reasonable.

Dian Hua reported the title of the book and the name of the author to the guardian behind the desk! One of the two guardians was in charge of the lettering record, and the other used the mechanism to open a deep secret passage, and then entered it and closed the entrance to the secret passage from the inside.

In the process of opening the door, the guardian who opened the door and the guardian who left a record behind the table, and even the two guardians at the door, kept an eye on Dianhua's reaction until the entrance to the secret passage was closed from the inside.

'The ancient people's awareness of the protection of knowledge is beyond imagination!'

While waiting, the bored Dianhua paced around along the aisle between the bookshelves.

The wall is a stone wall, and the stone wall is hollowed out with a seashell-like groove that resembles an erection of the ordinary, and a bronze eagle-shaped oil lamp is placed inside.

After Dian Hua stepped forward and took a closer look, he understood the benefits of such a design, one is fire prevention, and the other is light gathering.

Following the smoke of the lamplight, Dianhua discovered the ventilation system of this secret room, a row of vents only one foot apart by the thickness of chopsticks.

There was a bucket in each of the four corners of the room, and when Dianhua approached, he found that the water in it was very clear and clear, and there was no peculiar smell, and it seemed that the water was changed frequently, even every day.

This wooden barrel is also supposed to be used for fire prevention, and if a fire breaks out, the water in the barrel is used to extinguish the fire immediately.

If you look closely, there is a fish less than three inches hidden in the corner at the bottom of the barrel.

Why raise a small fish?

It should be the same as changing the water to prevent insects in the water, right?

In addition to being afraid of fire, bamboo slips are also afraid of insects, so there is such a design.

Looking closely at the bookshelf, I found that his material was actually metal, and the outside was coated with a layer of lacquer similar to the color of wood.

"It's no wonder that the labels on the bookshelves have to be specially hung with wooden signs, because the original bookshelves are made of metal, and the lettering is too difficult. ”

As for why the bookshelf is made of metal, it should also be because of fire and insect resistance.

As for why the paint is painted, one is because it is rust proof, and the other is because it is beautiful, right?

Dianhua picked up the bamboo slip and looked at it carefully, there was an obvious oily layer on it, and it smelled slightly pungent smell.

'The bamboo slips must have been professionally processed. ’

Dian Hua doesn't know what kind of treatment it looks like, but what can be determined is that it has a process of immersion oil.

Dian Hua can only guess the effect of the treatment, the oil immersion should be to increase the shelf life and moisture resistance, and the pungent smell should be to prevent insects.

As for whether there are other procedures and what the other procedures do, it is unknown that Dian Hua has not studied them specifically.

'The ancients really attached great importance to the protection and preservation of books!'

This aspect may be more important than modern people.

After all, in ancient times, people did not have electric lamps and induction cookers, and they used a lot of open flames such as oil lamps and stoves in their lives, and many of the appliances used in their lives were wooden products, and most of the houses were civil structures or all wooden structures, which were flammable.

Fire and water are ruthless, and once a fire breaks out in the ancient world, it will be a very serious disaster!

Because there are too many lessons learned, the ancients had such a strong sense of fire prevention, right?

"It's dry, watch out for candles. ”

Even throughout the night, special guards were arranged, and during the patrol, they sang and shouted loudly, specifically reminding everyone to be more careful at night and pay attention to fire prevention.

When he came back to his senses, he realized that the book he was going to borrow had already been picked up by the Guardian.

These guardians were really like wood, they didn't say a word, they didn't make a single superfluous movement, and they didn't remind me to go and get the borrowed books out of the stacks. ’

Dian Hua walked over and glanced at the dozen or so large bamboo slips on the tray, which weighed eight or nine catties when held up.

A book weighs eight or nine pounds of bamboo slips, and when I think of modern thin paper and even electronic books, my heart is full of nostalgia.

When Dian Hua walked out of the inner room and came to the teahouse-like hall, he found Qi Yu sitting at the tea table by the window, holding bamboo slips in both hands, smiling and reading intently, his eyes were happy, and he seemed to have gained something.

Dian Hua also likes the window position, but fortunately the hall is spacious and bright, with four windows on the walls on both sides and four coffee tables by the window.

Dianhua had a good impression of Qi Yu, so he walked to Qi Yu's side, sat down at another table by the window, and put down the tray.

It may be that the sound of putting the tray is a little loud, which alarmed Qi Yu, who was concentrating on reading, Qi Yu saw Dian Hua sitting at the opposite table, lifted the teapot in the middle of the table and nodded in greeting, and asked, "Dao Chief, do you need tea?"

After Qi Yu said, Dianhua was really a little thirsty.

Dian Hua looked at the steaming teapot in the other party's hand, lifted the empty teapot in the center of his tea table, and knew in his heart that this should be prepared by the other party himself in advance, not by the library pavilion.

After all, Qi Yu is not like Dianhua, the first time he came to the library pavilion, he knew that only teapots and bowls were provided, not tea, and he could only prepare his own tea if he wanted to drink.

Dian Hua put down the empty teapot in his hand, didn't know how politely he picked up the tray he had just put down, got up and walked towards Qi Yu and nodded with a smile: "Thank you, Master Yu." ”

Then he sat down unceremoniously opposite Qi Yu, picked up the teapot full of tea in the center of the table with his left hand, picked up an empty tea bowl on the table with his right hand, poured half a bowl of tea into it, picked up the tea bowl and looked at the color of the tea, smelled it again, and then frowned and took a small sip gently, his brows furrowed even deeper.

"This tea ......"
