Zhang Ning asked again: "Then what are you doing? Do you need me to help you?"

Han Nuo was not polite, saying, "Of course I need your help. But I don't have to hurry up. Let's talk about you coming to me first, what's wrong."

Zhang Ning suddenly felt relieved and said, "Ah, yes, we came because the things you asked us to prepare before were almost busy. Do you think you should go and have a look?"

Han Nuo said in surprise, looked at Zhang Jiao and asked, "So fast?"

Zhang Jiao nodded and said, "This matter is more important, so we must naturally take it as soon as possible."

Han Nuo immediately stood up and said, "Then let's go over and take a look."

On the way in the past, Han Nuo realized that because Guangzongcheng had him as a helper, Zhang Jiao planned to let Chu Feiyan return to Julu. There was no general there guarding him, so he was always worried.

Before Chu Feiyan went back, it would be best to see what the so-called papermaking and printing are going on. If he could, he would do it directly after he went back to Julu. Even if he couldn't do it, he could prepare it first.

Han Nuo knew that Zhang Jiao had some other reasons, and wanted to ask Han Nuo to hand over the two techniques as soon as possible.

Han Nuo sincerely wanted to help them, so he naturally didn't bother to care about their thoughts.

At this time, we came to a forest, and there was a small river beside the forest. Han Nuo specifically instructed that the place they chose was the lower reaches of the river.

Papermaking was already in the pre-Qin period as early as the Western Han Dynasty, and even the pre-Qin period, and the later technology was considered mature, but the quality of the paper produced was not good.

Eighty years ago, Cai Lun only improved papermaking to make the paper look better and make it easier to make.

Therefore, Han Nuo did not hide anything. In this selected venue, he explained it one by one with the listening of various craftsmen.

Papermaking is generally divided into nine steps: cutting hemp, washing, soaking ash, steaming, pounding, beating, paper making, drying paper, and peeling the paper!

The technology in later generations was just improved in these nine steps.

Even though these craftsmen have never been exposed to papermaking, these steps are not difficult, and Han Nuo explained in detail, so they could easily understand it.

"So that's it, mulberry or vine peel can be done?"

"Wheat rod and rice rod are OK?"

Han Nuo nodded: "Of course. In fact, there is also bamboo, but now it is difficult for you to do it. It is easier for you to use it like the mulberry vine."

"Just like wood ash water?"

"Yes, if you can find a better one, you can use lime water naturally. If you don't have it, just use wood ash water."

The craftsmen asked the questions one by one, and Han Nuo also answered them one by one.

As for the explanation of printing, it is a bit troublesome.

Because paper is rare at this time, books are spread by hand.

Of course, there are also considerations about whether you have a good memory than a bad pen.

But there was indeed no sign of printing at this time, and some were just prototypes such as seals, clay seals, rubbings, etc.

Printing originated from Taoist woodblock printing, which happened after the papermaking in the Jin Dynasty was introduced to Jiangnan and paper became popular.

In the middle and late Tang Dynasty, woodblock printing was widely used. By the Northern Song Dynasty, Bi Sheng invented movable type printing, but because of the small variety of books and the small output, it was not widely used.

For the craftsmen at this time, this printing technique was a craft that they had never seen before and had not even heard of, so it was naturally difficult to understand.

Han Nuo started with woodblock printing.

Han Nuo directly wrote the five words "Che Shang Tianranju" on a piece of Cai Hou paper, and then pasted the front of Cai Hou paper on a flat and smooth thick wooden board.

The words I saw at this time were the reverse character on the back, and Han Nuo asked the craftsman to cut off the parts that were not written.

An old craftsman was elected and quickly cut it out.

At this time, I looked at it again and there was a positive text with a convex font on the wooden board, which was completely different from the negative text of the stele with a concave font.

Concave and convex, positive and negative are completely opposite, just like the opposite yin and yang.

Han Nuo then asked someone to apply ink on the protruding handwriting on the wooden board, then took a piece of Cai Hou paper, pasted it on the wooden board, wiped the back of the paper, and rubbed the handwriting!

Han Nuo asked the craftsmen to take a piece of paper and print it.

“Is this printing?”

Looking at the five characters printed, the craftsmen looked around and compared, and after comparing, they found that the handwriting was exactly the same!

"That's great!"

"Yes, using this method, you won't have to copy so hard anymore!"

"It's okay to have as many books as you want! Just enough paper tubes!"

"By the way, did you teach us papermaking?"

"I see!"

"Sir, wise!"

Amid the compliments of the craftsman, Han Nuo waved his hand and said, "Do you think it's just this? This is not all!"

"ah?"

"what else?"

Zhang Ning saw the magic of this printing technique next to him and asked excitedly: "Isn't this real printing technique?"

Han Nuo did not rush to answer and asked first: "Are they all trusting?"

Chu Feiyan, who had been watching quietly by the side, replied in a deep voice: "This is natural!"

Zhang Niujiao also said from the side: "Look at them to speak out!"

Han Nuo nodded: "Okay. You have seen the next thing, but you must not tell me!"

The craftsmen responded repeatedly in Zhang Niujiao's eyes: "Yes, yes, yes, I will never say it."

Han Nuo drew out the new big sword, slashed six times in a row, and took out all the five words above!

Five characters, five pieces of wooden boards with the same length.

Han Nuo changed the order of these five wooden boards and became "Just the Sky Guest"!

"This!" Zhang Jiao understood first and said in surprise: "Can this be like this?"

Zhang Ning took Zhang Jiao as his disciple and taught Taoism. He was naturally smart and understood. He immediately snatched a piece of Cai Hou paper and rubbed a copy on the spliced ​​wooden board.

The five words "Actually the guest in the sky" are vividly displayed on the paper!

"Is this the real printing technique?" Zhang Ning asked excitedly.

Han Nuo nodded: "Yes, this is the real printing technique!"

Zhang Ning turned around, separated the five words, and then formed the order of "Che Shang Tianran House" and printed another copy.

The five words on paper are naturally the words "Cheers and Tianranju"!

At this time, even as dull as Zhang Niujiao understood!

Zhang Jiao took two different pieces of paper together and recited: "The guest is at Tianranju, but the guest is at Tianranju! Good! Good! Good!"

Only then did Zhang Jiao truly believe in Han Nuo, not only believed in Han Nuo's identity as a god descending to earth, but also believed in his sincerity to help him!

Three Enlightenment Classics, "Three Character Classics", "Hundred Family Names", and "Thousand Character Classics", plus this papermaking and printing technology, Zhang Jiao still doesn't believe in his sincerity!

Such a great gift would be presented to the Han Dynasty, which would be enough to be a marquis and ministers!
Chapter completed!
