"Oh, what gift?" A hint of surprise flashed in Tian Dan's eyes, he had already been rewarded by Mrs. Lan, after Lu Yunzhou solved the matter of Xueyan, he did not return home halfway, but came directly to Xiangguo Hall to see him.

Could it be that Lu Yunzhou had long expected that he would summon him tonight, and even wore the gift on his body before going out when he was going to arrest Blood Yan tonight?

The performance of Lu Yunzhou has given Tian Dan a deep understanding of his superior intelligence, and he has long stopped treating him as an ordinary young man, on the contrary, Tian Dan now thinks that it is not too much to think highly of and attach importance to Lu Yunzhou.

From the moment Lu Yunzhou stepped into the door of the study tonight, Tian Dan had an intuition, Lu Yunzhou's eyes carried a kind of eager initiative, he was not just called back by Tian Dan, he came here for his own purpose!

Combined with Lu Yunzhou's performance tonight, layer by layer, increasing the weight of his words, it was not until this moment that he officially established a preliminary tacit understanding and trust with Tian Dan, and then took out this so-called "gift".

Tian Dan even had reason to suspect that Lu Yunzhou planned to capture Xueyan with such fanfare, maybe it was to rely on this credit to get his own summons, and then present his carefully prepared "gift" to his case without a trace!

Thinking of this, Tian Dan was curious about Lu Yunzhou's gift.

What was it that made him insist on carrying it with him when he was chasing down the Assassins, and that he was willing to take it out after so long to lay the groundwork?

Under Tian Dan's gaze, Lu Yunzhou took out a paper envelope sealed with fire paint from his arms, as well as a thin book, which was also paper.

Papermaking, Lu Yunzhou had already asked this uncle to help him start manufacturing privately on the day Qi Jing came back, and it wasn't until this afternoon that Lu Yunzhou returned home, and the first batch of finished products had just been made!

All afternoon today, Lu Yunzhou stayed in the mansion, not waiting for Qi Ting to come back and give him the golden soft armor, but was busy tinkering with the letter and this small booklet.

This is the first time that paper has come out in this era, Lu Yunzhou took these two things that seemed very light and small, but were actually of great significance to this era, got up and walked to Tian Dan's bookcase, and solemnly put them on the bookcase.

"What is this?"

Tian Dan looked curiously at the thin book on the bookcase, as well as the letter, reached out and rubbed the material, and found that it was a material that he had never seen before.

"Back to Tian Xiang, this is a gadget I made some time ago unintentionally, called paper, Tian Xiang might as well take a look first!"

Lu Yunzhou explained, then returned to his seat and sat and waited.

Tian Dan glanced at Lu Yunzhou in surprise, and picked up the small book first.

I saw that on the cover of the book, it was written--"Guanzi < Jingyan > Nine Articles", which are tall and handsome, and the pen is a dragon and snake.

Tian Shan nodded, he recognized that this was Lu Yunzhou's word!

Before Lu Yunzhou came to this world, although Qi Yu was a well-known prodigal, he was also very famous in Qi State, otherwise he would not have been entrusted with a heavy task at a young age in the original book, and sent Zhao Guo alone to hook up with Mrs. Ya.

Lu Yunzhou's handwriting naturally inherited the skills of the original owner!

The book "Guanzi" is a book written by scholars of the Guan Zhong School of Qi after Guan Zhong's death according to Guan Zhong's ideological strategy for governing the country during his lifetime.

The whole book of "Guanzi" has 160,000 words, in addition to the nine articles of "Jingyan" in Tian Dan's hand, there are eight articles of "Foreign Words", seven articles of "Internal Words", seventeen articles of "Phrases", five articles of "District Dialect", ten articles of "Miscellaneous Articles", four articles of "Guanzi Solution", and sixteen articles of "The Light and Weight of Guanzi".

The book mainly records the governing methods of Guanzi, with a strong Legalist color, and also combines some of the ideas of Confucianism, Taoism, and light and heavy families, as well as a large number of military thoughts, involving all aspects of politics, military, economy and other aspects needed to govern the country, which can be described as the best guide for the rulers of this era!

The sage Guan Zhong is the common idol of the people of Qi State, and it is also the person most revered by Tian Dan and King Qi, and the people of Qi know that Tian Dan worships and wants to emulate the "middle father" Guan Zhong who assists the Duke of Qi Huan, and the book "Guanzi" is also Tian Dan's favorite reading on weekdays.

The titles of the five highest officials below the prime minister of Qi State: Da Sima, Da Si Tian, Da Si Xing, Da Si Li, and Da Ji, also Tian Dan insisted on retro after the restoration of the country, and followed the central official system set up by Guan Zhong that year.

In the future, the title of "middle father" of Lu Buwei of Qin State is just an imitation of Guan Zhong, the difference is that Guan Zhong's "middle father" is a title that Qi Huan Gong willingly and voluntarily honorifies, unlike Lu Buwei, who imposed it himself in order to step on Yingzheng's head.

And now Lu Yunzhou specially presented this paper version of "Nine Articles of the Pipe < Sutra >", which is naturally to do what he likes and show his favor.

Seeing Tian Dan open the "Nine Chapters of the >< Pipe and the Scriptures", Lu Yunzhou explained: "This batch of papers was just made at noon today, and the time is limited, so I copied the nine articles of the "Scriptures" first, and showed Tian Xiang the effect, as for the rest of the content, after I go back to complete the binding, I will dedicate it to Tian Xiang together!"

Tian Dan held the thin book in his hand, but his hand couldn't help but tremble slightly, as if he couldn't believe it, he gently rubbed the material of the paper in his hand again, slowly looked up at Lu Yunzhou, his eyes suddenly became fierce, and slowly asked: "Qi Yu, you tell me, this kind of ...... Is the manufacturing process difficult, what is the output, and what is the cost?"

Lu Yunzhou smiled: "This first batch of paper was made in only five days, the output is conservatively estimated, at least it can be filled with a car, the cost is very low, whether it is the material, the cost is lower than the cost of bamboo slips, and the manufacturing process is also very convenient!

The invention and development of paper is a very long and tortuous process. The appearance of paper was in the Western Han Dynasty, but the paper of the Western Han Dynasty was very expensive, and the quality was very poor. In the Eastern Han Dynasty, Cai Lun improved the papermaking technology, and the manufacturing cost of paper was greatly reduced, but due to the limitations of the process, it was not possible to make large, satisfactorily white paper, so it still did not achieve widespread popularity. In the Three Kingdoms period, bamboo slips were still the main writing carriers.
