From the prosperous era of Han Wu in the Western Han Dynasty, Yan Yan also mentioned the prosperous era of the Ming Dynasty in the Eastern Han Dynasty, the prosperous era of the Kaihuang Dynasty in the later Sui Dynasty, and the later prosperous era of the Tang Dynasty.

All these prosperous eras have one thing in common: political openness, ideological emancipation, abundant talents, vast territory, consolidation of national defense, and most importantly, national harmony.

If nothing else, let's just say that during the prosperous period of the Tang Dynasty, Chang'an City gathered people from all walks of life such as monarchs, envoys, merchants, monks, students, craftsmen, doctors, etc., who not only brought their own advanced technology and advanced culture, but also brought the advanced technology and culture of the Tang Dynasty back to their own countries, completing the integration of economy, culture, handicraft, music and dance, etc., which had a huge impact on the society and culture of the Wa Kingdom, Goryeo and even the countries of the Western Regions.

Of course, the premise of opening is that we have strong national strength to support, that is to say, what we need to do now is not only to prepare for war with those countries, but more importantly, to increase our own national strength, so that the people are rich, and the people are rich, the treasury will naturally be full, so that we can afford to raise more troops to deter these countries." Yan Yan concluded.

She had obtained these words by combining what she had learned in the previous life and what the original owner had learned in this life, and she herself definitely did not have such a rich knowledge of history.

"But how can we increase our national strength?" Li Sui asked.

"Vigorously develop agriculture, handicrafts and commerce. Not to mention the far, just to say the near, still take the Tang Dynasty as an example, the Tang Dynasty's agriculture has developed greatly, first of all, they improved the structure of the plow, made the Quyuan plow, and created a new type of irrigation tool barrel car; secondly, a large area of water conservancy was built, a series of irrigation canals were dug in the Yellow River and Yangtze River basins, and old canals and weirs were repaired. Third, a large amount of barren land should be opened. ”

Yan Yan paused, and Li Sui interjected and asked, "Sister Yan'er, no wonder you bought such a large piece of barren mountains and barren mountains, and you searched for novel seeds everywhere, it turns out that you want to emulate the Tang Dynasty." ”

"Yan'er, where did you get these from?" Yun Ze asked.

"In the past six months, I have turned over a lot of agricultural books for taking care of barren mountains and looking for new seeds and planting methods, which are recorded in the books." Yan Yan replied generously.

Because these contents are indeed what she sees from the book, but none of the people here have ever read agricultural books or paid attention to the field of agriculture.

This is understandable, after all, there is a specialization in the art industry.

"What about the crafts?" This time it was Li Zhi who asked.

"The handicraft industry of the Tang Dynasty is mainly manifested in the textile industry, the ceramic industry and the paper industry, which they use to communicate with those Fanbang countries in exchange for the lack of leather goods, precious stones, spices, medicinal materials and other things that are lacking in the Central Plains. When it comes to handicrafts, in fact, we also have technology in Dazhou, but our workshops are generally self-sufficient, because the overland Silk Road has been cut off by these Fanbang countries, and our goods can't be sent out, and Fanbang's goods can't come in. That's why I suggested to the emperor to open up a sea passage and open a few more coastal cities. In fact, it is not called opening up, because in the middle and late Tang Dynasty, due to the war, they have opened up a sea route on the southeast coast, which is said to be thousands of miles away, passing through more than 100 countries, we only need to find out this route according to historical records. ”

The reason why Yan Yan suggested this was because she knew that the maritime trade in the Northern Song Dynasty was very developed, so don't look at the strength of the Song Dynasty's army, but the economy was very developed.

"I know this, there were a lot of boats in my hometown before, and then because of the war, all these strong laborers were drawn to be soldiers, and now they say that they want to fight, and this sea route is not so easy to build." Yun Ze said.

He was worried about the silver needed to build a large ship on the one hand, and the sailors on the other, because he knew that there would be robbers not only by land, but also by sea, so he would definitely not be able to run one or two ships on such a long road, but to build a fleet, and the silver taels and manpower required were definitely not a small number.

In peacetime, maybe you can draw out this money and manpower, but now is the period of preparation for war, both of which are lacking in the Great Zhou, and the emperor must prioritize them, and the current importance and urgency are war.

Yan Yan is also aware of this, so she has a proposal, that is, she wants to raise funds from the private sector to build a fleet, although the treasury is empty, but these merchant families must have silver in their hands, and they will take the lead in forming a fleet, although most of the benefits go into their purses, but the state can at least receive a certain amount of taxes, and at the same time can feed a lot of people.

"That's a good idea, you told the emperor?" Yan Peng asked.

Yan Yan shook his head, "The emperor is most concerned about the war in the north now, and besides, I also have a superficial idea, I have mentioned it to the emperor before, and I haven't specifically touched on these, I... ”

Before Yan Yan's words were finished, Qingxiu suddenly ran over, saying that there was a distinguished guest at home, Yan Yan was about to ask what kind of distinguished guest it was, only to see Li Cong striding along the folding board bridge, and there were four guards standing behind him, but they didn't go to the bridge, but looked around vigilantly.

When Yan Yan saw it, he hurriedly helped Lu You to stand up, just walked out of the pavilion, and before he knelt down, Li Cong stepped forward to help her up, "Flatten, this is in your house, you don't need so many rules." ”

Having said that, Yan Peng and Yun Ze had already knelt down at that time, "Weichen knocked to see the emperor." ”

"Let's all be flat, you are not outsiders, don't talk about these false courtesies, I just came out of Cining Palace, I heard that a few of them haven't returned to the palace yet, I am curious about what Yan'er is doing for you to eat, so I also came to join in the fun." Li Cong said as he took the initiative to walk to the middle of the pavilion and sit down.

Seeing this, Yan Yan ordered someone to prepare a new set of tea sets for him, and also ordered someone to bake a few fish and shrimp for him again.

"It's a coincidence that my father came, we are discussing with Sister Yan'er how to strike the war with Fanbang, how to fill the treasury, how to open up sea routes, etc., no wonder the old saying goes, listening to the words of the king is better than reading for ten years, Erchen listened to Yan'er's sister's words, and was very ashamed, Erchen is several years older than Yan'er's sister, but there are many fewer books to read." Li Sui said.

He still knows his father better, and knows that his father has always respected Yan Yan, and he is afraid that most of his words will be directed at Yan Yan's remarks when he goes out, so he didn't wait for his father to ask questions and said the content of Fang Cai's conversation.
