Da Qin: At the age of six, I beat Qin Shihuang at the beginning

Chapter 45 Ice making, Lie Yufeng will take the blame again

Of course Zulong has seen ice, especially in winter, the temperature in Xianyang City is still very cold.

It is a bit of an exaggeration to say that dripping water turns into ice, but freezing three feet in deep winter is also a common sight.

In palaces with wooden structures as the main body, there are often special large tanks for storing water.

This is a specially prepared water source to prevent fires in the palace.

But... when it comes to winter, these big tanks are useless.

The water inside often freezes into hard lumps of ice, which cannot be cut with a knife.

Zulong once imagined how great it would be if these ice cubes could be preserved until summer?

In the hot summer, sweating like rain, put two ice cubes by your side to cool down instantly!

It's just that the craftsmen tried many times, but they couldn't find any good method.

The best thing to do is to keep the ice until early summer - but that's not the time to use it.

Therefore, Zulong's current shock can be imagined.

This is the hottest time of day!
How could the ice that could not be stored in the imperial palace appear in Qin Mu's hands now?

Dian Wei exaggeratedly put his face in front of the ice cube, trying to absorb some cold air from it.

Nei Shi asked about the execution at noon, and he was sweating from the sidelines watching the execution.

Dian Wei sucked in the cool air greedily, and asked, "My lord, where did you get this ice cube?"

Qin Mu was speechless.

The co-author Dian Wei just told him about the execution scene of the internal history for a long time, and he didn't notice the ice cubes in his hand at all?

Qin Mu glanced at Dian Wei, and said, "Of course I did it myself, or could God have changed it for me?"

Zu Long also came up and asked, "Mu'er, how do you make this ice cube?"

Qin Mu rolled his eyes: "Why did I tell you? Where are my wives?"

Zu Long said with a smile: "Isn't there a lot of things these days? In a few days, I promise to call you over in a few days."

Only then did Qin Mu coolly explain.

"This ice cube mainly relies on an alchemist's alchemy material called saltpeter!"

"As long as we prepare enough saltpeter, add it to the water, and wait for a while, the water will freeze naturally!"

Zu Long and Dian Wei waved his hands, motioning for them to follow.

After entering the study, the two of Zu Long found that there were two water basins in the study.

The two water basins were actually full of cold ice cubes!
Entering this study at the moment, it's like walking into winter, even a little cold!

You know, it's midsummer now!

"These two basins are our ice-making props."

"These two pots are one big and one small. The big pots are whatever you want, and the small pots must use iron or copper pots."

"Fill the two basins with water, and put the smaller basin into the larger one."

"After that, you just need to add saltpeter to the big basin, and keep adding until the big basin is completely frozen."

"Finally, the ice cubes in the big basin will freeze the water in the small basin into ice. The ice cubes in the small basin are ready to eat!"

"You can make iced juice, shaved ice, iced watermelon... Oh, there is no watermelon in Daqin... What a pity."

Zu Long didn't bother to ask what is a watermelon, he now has a more concerned question.

"Mu'er, why do you put a small basin in the big basin? Can't the big basin just freeze?"

Qin Mu shook his head and said, "Saltpeter cannot be eaten directly, it causes cancer..."

"Cancer?" Zulong wondered.

"Hey, forget Dad, you don't understand."

Qin Mu slapped his head: "It's a terminal illness, the kind that waits to die when you get it."

"This... this method is too amazing!"

Zulong circled the water basin twice.

"I've seen this saltpeter before, and even alchemists use it every day. No one has discovered such a strange use!"

Zu Long stared at Qin Mu with bright eyes: "You came up with this?"

Qin Mu sighed, at this time, it's time for Lie Yufeng to take the blame again.

"Well...my master discovered it."

Zulong directly looked up at the sky.

This row of Yufeng is really amazing!

If it is said that after being a fairy, it is normal to know some medical skills and prolong life.

It is normal to have a high political vision, after all, with a long life, I have seen a lot.

But now he actually still has this kind of method that is almost miraculous!

Doesn’t making ice in summer reverse winter and summer?
This kind of miraculous method may only be possessed by immortals.

Zu Long further confirmed that Lie Yufeng is the descendant of Liezi.

As for Qin Mu, he is a top talent that he must cherish.

Even if Qin Mu didn't invent these methods, but he knows how to use them, that's enough.

Looking at Zu Long's face, Qin Mu knew that he was going to start praising Comrade Lie Yufeng, Comrade Backer.

Thinking of Zulong's bragging last time, which made him feel numb for two days, he quickly changed the subject.

"Father, how did you use the movable type printing that I taught you last time? How many books have you produced now?"

When Zu Long talked about business, he immediately switched to a very serious state.

He shook his head and said, "Not many. Although the process of copying is omitted in the current books, the speed is still very slow."

Qin Mu asked: "Why? Not proficient in movable type printing?"

"That's not it."

Zu Long took a sip of the iced juice Qin Mu handed over, and sorted out his words.

"The first is that the length of the bamboo slips is limited, and a few words cannot be printed on a single bamboo slip."

"Secondly, the bamboo slips themselves are curved, so in many cases the drawn characters will miss one side."

"The third is that the printing is fast, but a book still weighs tens of catties, and it is difficult to disperse and transport it to all parts of the country."

Qin Mu nodded.

Daqin's current books are carried on bamboo slips.

Even if he innovated the printing method of books, the bamboo slips themselves are the biggest factor restricting the circulation of books.

The problems summed up by Zu Long are almost all caused by the bamboo slips themselves.

He thought for a while and asked, "Have you guys tried printing books on other things?"

Zu Long glanced at Qin Mu in surprise, and said: .

"You are clever. The craftsmen tried various materials and found that the most suitable ones were those that were soft and flat."

"The best and best printing material they have found so far is silk."

"It's just that silk is too expensive. If it's printed on silk, I'm afraid even those rich landlords can't afford it."

Qin Mu asked tentatively, "Have you tried anything else?"

Zu Long smiled wryly: "I have tried everything. Except for silk, the best effect is wood."

Qin Mu was speechless. Could it be that Comrade Lie Yufeng should take the blame for papermaking again?
He was about to speak when he heard a thunderous sound from Zulong's stomach.

Well, the first time I ate something iced, I ate so hard, and the retribution came.

He didn't speak, and pointed in the direction of the hut.

Zulong forcibly controlled and walked into the hut.

Then, he discovered that there were a large number of things that were as white as snowflakes and as soft as silk, but which he had never seen before in the hut.

He reached out and took a sheet, this... can it be used to print books?
