"The Gongshu Fuzhen has met the king!" The craftsman with long face and small eyes respectfully saluted Zhao Dan.

Zhao Dan looked at the craftsman in front of him and smiled very gently, "Are you a Qin?"

Gongshu Fuzhen replied respectfully: "The king, I am from Hedong County."

When Gongshu Fuzhen said this, Mao Sui, who was standing behind Zhao Dan, suddenly flashed a strange look in his eyes.

Zhao Dan showed a stern expression and said, "Okay, let me tell you what this printing technique is like."

As soon as he talked about this topic, Gongshu Fuzhen immediately became energetic and exclaimed at Zhao Dan: "King, this papermaking technique is a strange thing that I only see in my life."

Zhao Dan waved his hand and said, "Tell me the point."

Since the emergence of paper, Zhao Dan has started to use it in daily life. Although the paper produced is not much, he cannot stand Zhao Dan is the real king of Zhao.

Zhao Dan had long had enough of the life of holding hundreds of kilograms of bamboo slips in his hands every day.

Of course, as a wise king, Zhao Dan did not give the good thing paper, and all the ministers also distributed some.

So Zhao Dan had long heard of the praise and praise of paper like Gongshuofuzhen.

Gong Shufuzhen realized his incompetence, and hurriedly accused him of guilt and led Zhao Dan to a workbench.

It is said to be a workbench, but it is actually just a huge stone table that has been quite flat.

There are many utensils placed on this stone table in a very chaotic manner. Zhao Dan didn't recognize many of the utensils at all, or they were very different from the appearance of later generations.

Once you walk here, you can smell the strong smell of wood and ink.

Gong Shufuzhen picked up a wooden board and said to Zhao Dan: "King, this is the carved plate."

Zhao Dan looked closely and found that there were many small characters engraved on this woodblock, and each small character was inverted.

According to the introduction of Gongshufu, the selection and processing of this wooden board material is actually very particular.

The craftsmen of Zhao State have prepared many woods, such as pear blossom trees with moderate hardness, boxwood with tough and smooth texture, pear blossom trees with equal hard texture, ginkgo trees, poplar trees, jujube trees, etc.

Then saw them off, soak them in water, then dry them, and then flatten them, a very smooth-looking wooden board was born.

Carving words on such wooden boards is much better and more convenient than directly constructing on a piece of sawed blank.

After hearing this, Zhao Dan was also amazed. Although he didn't know how the printing technique was done in later generations, judging from the steps introduced by Gongshu Fuzhen, the printing technique is not simple at all.

Zhao Dan said: "Come on, print a page and show me."

Gong Shufu really respectfully agreed, then picked up a brush dipped in ink and brushed it back and forth on the wooden board for a while, then put down the brush, picked up a piece of paper from the side and covered it on the carved plate. After a while, he took the paper down and presented it to Zhao Dan.

A new page with several pages written in the Book of Songs: Qin Feng appeared in front of Zhao Dan.

Zhao Dan took the page with a strong ink fragrance, looked carefully for a while, and then nodded with great satisfaction.

"Yes, this is exactly what I want."

With a carved plate, it is actually not possible to solve the problem. There must be appropriate ink.

The printing ink is actually different from the writing ink.

If you use writing ink to print, the ink will melt and penetrate into the paper, resulting in blurred handwriting.

Once the handwriting is blurred, the printing will naturally fail.

According to the master craftsman around Zhao Dan, this is the problem that has always troubled the craftsmen of Zhao State.

"How did you solve this problem?" Zhao Dan looked at Gongshu Fuzhen in front of him with great interest.

Gongshuofu Zhen picked up a piece of black paint from the stone table, which looked like black charcoal and said to Zhao Dan: "Go back to the king, my father and grandfather once developed a kind of ink, which is called black smoke ink, which is an excellent thing for printing."

"So that's it." Zhao Dan was in a good mood and asked, "Your method of making smoke and ink can be handed over to me?"

Gongshu's tummy is obviously hesitant.

Zhao Dan waved his hand and said, "If you are willing to hand over this Yanmo method, then I will be given a fifth-level title and a bounty of 10,000!"

"Give the title to the fifth level!?" The faces of the big craftsman and Mao Sui next to him changed at the same time, and they all showed an envious expression.

This is definitely a big deal.

Gongshu Fuzhen immediately bowed down: "I would like to present this recipe of ink to the king!"

After being promoted to five levels in a row, Gongshufu was already qualified to submit to Zhao Dan.

"Very good." Zhao Dan looked at Gongshu's tummy with a smile and said, "From today on, you will be the master of this printing house."

Gongshu's belly looked obviously quite excited, his whole face turned red, and he suddenly said, "I'm not hiding the truth about the king. In fact, my ancestors have also passed down some methods of making weapons and crossbows. I am willing to offer them to the king."

"Weapon bow and crossbow?" Zhao Dan was stunned for a moment, then a happy expression appeared on his face: "Where is the drawing?"

Gongshu said respectfully: "King, it is not easy to keep these drawings. I have always kept them in my head. I also asked the King to come and try it after I made the finished product."

Zhao Dan nodded with a smile and said, "It's so great, so I'm waiting for your good news."

...

After returning to the palace, Mao Sui, who had been following Zhao Dan, suddenly spoke.

"Master, I think that the lord may have some problems."

Zhao Dan calmed down for a moment, then turned around and said, "What do you mean?"

Mao Sui said: "King, this Gongshufu is really a spy."

"What?" Zhao Dan's face showed a surprised expression: "Why is this?"

Mao Sui said: "King, although this person's accent sounds quite similar to the Hedong accent, he is definitely from Guanzhong."

"Guanzhong people?" Zhao Dan frowned and after a while, he said: "By this alone, I'm afraid he can't be determined to be a spy in Qin?"

Mao Sui continued: "The king doesn't know anything. I have recently read the information collected by the Hu Yiwei. I once saw an information that there was a unique formula in the Mo family of Qin, and the name of this ink is Black Smoke Ink."

Zhao Dan's face became solemn.

"If this is the case, then you will check it out for me to see how he entered this printing house and what plans he had."

Mao Sui paused, then whispered: "King, I actually have something I want to report to."

"What's up?"

Mao Sui said: "King, I recently discovered that there was a female palace maid next to Mrs. Mi. She took some opportunity to leave the palace quietly, and seemed to have had contact with Qin State."

Zhao Dan suddenly widened his eyes: "What happened?"

Zhao Dan was really angry this time.

First, there was a guy who was suspected of being a spy in Qin State, and then another wife who might be a spy in Qin State.

These Qin people are really able to calculate, they all come to my head.

"Investigate, let me investigate hard! I want to see what the hell is this Qin man trying to do on my territory!"
