Konoha, I have the Herrscher of the End core in my body.

"Naruto, an overseas wanderer, greets His Majesty the First Emperor. Congratulations to His Majesty on unifying the Central Plains. I have a papermaking technique that I would like to present to Your Majesty." Naruto said as he waved his right hand, and the next moment ten copies of the Analects flew in front of the First Emperor Ying Zheng.

The reason why Naruto came to see Masago three days later was that he was considering what gift to give him for their first meeting. The witch's rejuvenation potion and the longevity rice are both good things, but in the end he decided to give him the papermaking technique. The previous things only benefited Masago, but the papermaking technique can benefit all people. Since he appeared in this world, he would naturally not allow Masago to die early. However, it is still a long time for Masago to die, so there is no need to take out the life-extending things so early.

On the contrary, papermaking is different. With it, there is no need to worry about the various schools of thought and the monopoly of knowledge by major families. Fortunately, in order to build the empire before, I have learned about papermaking. In the world of Sword Art Online, I have stored a lot of information in the tablet computer.

He has been doing related experiments in the past three days. If someone else came to this world, they might not have the conditions to complete the experiments. But who is he? He is the Herrscher of Reason. With this, there is nothing he can't create. Modern technological products, including home computers, refrigerators, televisions, air conditioners, etc., Naruto has used the ability of the Herrscher of Reason to analyze, understand and reconstruct them.

The reconstruction of the Herrscher of Reason can be divided into two aspects. One is to understand its structure and use your own knowledge to understand the reconstruction. The other is to analyze it purely with Honkai energy and then reconstruct it. The second method does not require learning specialized knowledge.

"The Analects." Ying Zheng looked at the book in front of him, read the words on it softly, then raised his hand to take a book and started to read it. After Ying Zheng took action, the ministers behind him also took the books in front of them. Naruto's ten copies of the Analects were not only sent to Ying Zheng, but the ministers behind him also had a share.

"Is this paper?" No one who could stand here was a fool. Combining what Naruto had said before, they immediately understood what paper was. At the same time, they also understood that this thing was much better than the so-called bamboo slips.

"Bring a pen." After flipping through the Analects, the middle-aged man standing behind Ying Zheng immediately ordered the eunuch beside him to bring a pen, and then began to write on it. Others, including Ying Zheng, were watching him write.

"Congratulations, Your Majesty. Congratulations, Your Majesty." He then immediately saluted Ying Zheng with both hands, and the others immediately followed suit.

"Hello, Mr. Naruto, I wonder what the output of this papermaking technology is?" The man then left and looked at Naruto and asked.

"That depends on the technology of the empire, but the advantage of paper is not only that it is easy to write on, but more importantly, it is very cheap. For books like this, even if you sell one for ten cents, you can still make a profit."

To be precise, what Naruto presented to Ying Zheng was not only papermaking, but also movable type printing. These two technologies together were enough to make the Qin Dynasty move forward hundreds of years.

"Technology, mechanical engineering?"

"You can understand it that way." It turns out that the ancients were not fools.

"Xuan Gongshu family." Papermaking involves mechanical technology, so Ying Zheng immediately ordered the people of Gongshu family to come to the palace.

"Sir, I offer you this technique. What do you want?"

"I offer this technique mainly to congratulate Your Majesty on unifying the Central Plains and freeing it from war. Of course, I also have some personal needs. I heard that the Yin-Yang Family is subordinate to the empire, and I want their Yin-Yang technique." Naruto was not polite to Ying Zheng and stated his purpose directly. The Yin-Yang technique of the Yin-Yang Family, what he wanted in this world was the cultivation methods of Taoism and the Yin-Yang Family.

"Just that?" Ying Zheng was a little surprised by Naruto's request. In fact, Naruto didn't need to say it directly about the Onmyoji School's Onmyoji. After today, as long as he had the idea, he could get it.

"Your Majesty, please wait a moment. I have something else to offer you." Seeing that Ying Zheng was about to reward him, Naruto naturally knew the reason, but what he came to give him this time was not just the papermaking technique.

"Your Majesty, these are potatoes." Naruto immediately took out the potatoes. This thing is a powerful weapon in this era. The reason why he took it out now is naturally because planting takes time. For ordinary people, food is the biggest guarantee.

"Really?" When someone heard Naruto talking about the potato production, they immediately couldn't help but ask.

"Of course, this planting is easy, but of course you still need to study the details." Although there is information about potato planting in the tablet, it is a different world after all, so he can't guarantee it.

"Your Majesty, I have something else to report, but this." Naruto said this immediately after Potato. After thinking about it, Ying Zheng immediately dismissed his attendants.

"Your Majesty, do you know how big the world is?" After entering the imperial study, Naruto immediately took out a scroll. This was the world map he prepared. Although it was only a rough outline, it should be enough for Ying Zheng.

"This is the entire world, that's why you kept using Central Plains." After looking at the world map, Ying Zheng understood why Naruto had been talking about unifying the Central Plains.

"Your Majesty's lesson."

Then, when Ying Zheng was staring at the world map in silence, people from the Gongshu family arrived, so Naruto said goodbye and met with the people from the Gongshu family to explain the papermaking and movable type printing to them.

The person Naruto met here was not Gongshu Chou, but an elder of the Gongshu family. Gongshu Chou was not in Xianyang at that time. After hearing about the papermaking equipment that Naruto mentioned, he immediately said that there was no problem. The Gongshu family was worthy of being able to create the Hundred Battles Divine Crossbow in this era.

This world is Qin's Moon, but not the Qin Dynasty in orthodox history. For the Gongshu family who were able to create mechanical snakes, mechanical bats, Poto Saburo and Poto Chillang, modern technology was something they had not thought of. With Naruto to give them guidance, the Gongshu family's mechanical arts will probably have greater development in the future.

For example, Naruto told the Gongshu family about modern concepts such as assembly lines and molds. For modern people, basically everyone who has been to school knows these, but in this era, they are advanced knowledge.

"National Master, Great God of Destiny, Ying Zheng is really resolute and decisive."

Soon, the reward for Naruto came down. He was directly appointed as the national teacher, with a status comparable to the Moon God. The Great Sima of the Yin-Yang School was also sent over to deliver the Yin-Yang School's classics and be responsible for explaining them to him.

"Is this Yin-Yang magic? Now I have one more way to show off."

Learning Yin-Yang magic is not difficult for Naruto, the Herrscher of the End. Combining his memories, such as Yun Zhongjun stepping on the clouds, he can naturally step on the clouds as well. If he knew this before, he would definitely do it when he met Ying Zheng.

"Flat-bottomed Autumn Orchid, this move is very compatible with Wood Release. If a lotus is formed under the body, it will undoubtedly be more impressive."

Naruto thought so in his heart, and quickly formed a green lotus in front of him, then stepped on it and flew into the air. This scene made Da Siming, who was responsible for explaining Yin-Yang magic, couldn't help but open her mouth wide. She didn't just come to explain Yin-Yang magic, but also had the intention of testing Naruto's background. After all, Da Qin suddenly had a national master, and the Yin-Yang family couldn't help but care, especially after Donghuang Taiyi discovered that the fate of Da Qin had changed.

Donghuang Taiyi, the Moon God who was good at observing celestial phenomena, discovered that the celestial phenomena became chaotic the moment Naruto became the imperial teacher of Daqin. Donghuang Taiyi began to feel troubled by this. Originally, according to the plan of the Yin-Yang School, they wanted to use Daqin to achieve their goals, but now, the situation has changed.

"Deal with the Mo family? I have nothing to do anyway, so why not go and take a look? It's a good opportunity to see the mechanical Azure Dragon."

Naruto, who had only been in Xianyang for a few days, heard that Li Si had asked Liusha to deal with Gai Nie and Mo Jia, and immediately prepared to volunteer.
