In the early eighteenth year of Zhenguan, Zhang De, as an engineering dog, was a little unable to understand the truth. In Lao Zhang's view, there is no reason, so many places in China can't be planted, and so many domestic markets have not been developed, why should you go out to the waves and go to the sea?

Just because of the legend of gold and silver, or the iron mountain of copper?

It's not scientific.

Of course, Lao Zhang spread the map and chart on the table, and the scene was still spectacular. The estuary area of the South China Sea was more or less glued and filled by the Tang people.

From the Red River Delta in Jiaozhou, to the Mekong River Delta in Linyi Chenla, and then to the Chao Phraya River Delta, wherever a good port can be established and enclosed for stationing, there are ships built in the eighth and fourteenth years of Zhenguan.

This is a rather complicated era, the Tang people are not a small country and a small maritime people, for sea navigation, the comfort requirements are extremely high, so the general offshore is flat sand boats and the like. But for the sake of profit, the adventurers at the bottom of the north and south are willing to board the flat-headed pointed bottom boat......

This is an era when the number of sailors is far from enough, and the elimination rate is at least 20%. Twenty out of a hundred sailors died, much more terrifying than on the battlefield.

Even so, whether it is a horse or a boat, the north and south bottoms have to be on it.

"I see, the Guangzhou shipping company can occupy an area in Linyi, but it is actually because it helps to scare off the enemies of Wendan in Wuwen Mountain? And helped to beat the Zhenla people out of the Luolun River? ”

"The Fan family, the lord of Linyi, has always admired the Celestial Empire, and he paid tribute in the former Sui Dynasty, and in the fourth year of Wude and eight years of Wude, he also sent envoys to pay tribute. Now the biggest fire bead in Daming Palace is the Fan family's tribute. ”

"Is that the glass-like South China Sea Fire Bead?"

"Exactly."

"This Linyi is really docile, and the people of Guangzhou occupy 30,000 acres of land this year. Although they were all invited by the Fan family to help suppress the bandits, these 30,000 acres of land are all connected and very fertile. ”

"The states of the South China Sea are really strange, Zhenla can't beat the bandits, so they ask the Tang people to help. Lin Yi can't beat Zhenla, so please ask the Tang people to help. What is this? If you change to Turkic, I'm afraid you will have to fight against the Tang people first, or you will never ask the Tang people to go. ”

"It's just a small country, what do you know? Dingkou is not as good as a state in China, and such a lord is afraid that his life is not as good as that of the county order. How can you care about this? If he is rich and prosperous, he will be afraid, but in this situation, he has no doubt that he has him. ”

Within the Tang Dynasty, it was natural to feel that the countries of the South China Sea were simply in the water, allowing the Tang people's merchant fleet to occupy the territory.

However, the Tang people naturally don't think that they are really the thief, and there is a sentence "children swagger through the market with gold", isn't it? One day when Lin Yi loses the national honor, there really won't be anything to worry about, even if Lin Yi Fan has always been docile, but it's their business?

At this time, the routines of the north and south of the Tang Dynasty were different, and the southern country was especially prominent in Guangzhou Jiaozhou, and Li Daoxing was also quite hard for his "son". In addition to vigorously recruiting doctors, there is a branch of Tongren Medical Hall in Jiaozhou, ditching and dredging is done almost all year round.

Since stabilizing the situation in Jiaozhou, Li Daoxing has spent a lot of money and invited Wang Taishi's disciples to survey and map. At present, there is a data that is not known much in China, and only the officials of the six ministries and above can know. For this data, Li Daoxing also specially asked Zhang De to help forward a letter of "Jiaozhou Land Shu" to the eldest grandson Wuji, and then the eldest grandson Wuji gave it to his brother-in-law.

Li Daoxing spent more than a year surveying and mapping the arable land in Jiaozhou and came to the conclusion that it was more than 20 million mu. According to this data, at least half of the rice fields in Wuhan are at present, and the agricultural time in Jiaozhou is quite early, and the planting can be started in February, and the rice varieties used are relatively peculiar, which is Linyi early rice. Because Linyi is also known as Champa or Champa, this kind of early rice is also called Champa rice.

This kind of rice seed, which can be harvested in two months, enables Jiaozhou to have three harvests in a year. In the past few years, the investment in water conservancy was not large, and the grain output of Jiaozhou and Guangzhou did not show any advantages, but in the face of Li Daoxing, he smashed out the coffin to pave the way for his "son" and vigorously "invested" in Jiaozhou, and Jiaozhou's grain output, whether it was the total output or the yield per mu, has surpassed that of Guangzhou.

The population gap between the two states is huge, and there are also a large number of sugarcane fields, but the growth of grain production in Jiaozhou is very amazing compared to Guangzhou.

Since Li Daoxing took control of Jiaozhou, water conservancy projects have included the Jiaozhou Weir similar to Dujiangyan. Because of the construction of Jiaozhou Weir, the reconstruction of Jiaozhi City in this place, after the court was sparse, the county Jiaozhi was placed. Therefore, Jiaozhou weir is also called Jiaozhi weir.

After Jiaozhi County divides the water, the lower reaches of the Xidao River tend to be more gentle, the navigation capacity is great, to the eighteenth year of Zhenguan, the scene of Hebei slender man dragging eight years to build a big boat, is extremely spectacular.

And this section of the gentle river, because it is different from the West Dao River, most people in Guangzhou take the Jiaozhou Barbarian Zhu Kite Department as the name, call it the Zhu Yuan River, and also call the Zhu Yuan River. But no matter how it is called, the Jiaozhou Barbarian Zhu Kite Department no longer exists, after Li Daoxing gained a firm foothold, the surrounding 267 Jiaozhou Barbarian departments and holes were suppressed and appeased, including the Zhu Kite Department.

At present, the largest gathering place of the Zhu Yuan tribe should be a stone mine area in Danzhou.

The vigorous development of Jiaozhou was not unnoticed by the foreign dynasties, especially the successive establishment of Jiaozhi County and Zhuyuan County in Jiaozhou, which shows that the number of local population registered and the number of acres of land registered have a considerable scale.

And not only the imperial court, but also the civil forces did not let Jiaozhou go, whether it was because of Zhang De or Wang Xiaotong, or Li Daoxing and Li Jingren father and son themselves, Jiaozhou attracted a large number of private forces in Jingxiang and Jiangnan.

Even if it is not a powerful force, but it adds up, just a few years later, the low-level people in the south who are fighting in Jiaozhou can be regarded as "having a head and a face" in Jiaozhou, and the profits in Jiaozhou have enabled these people to "return to their hometowns", which has further stimulated the "low-level township party" to take risks overseas.

The cognitive convergence of the government and the opposition has also made Jiaozhou gradually have the conditions for another "important town" in the South China Sea after Guangzhou. In addition to Cheng Chubi's successful experience in the Western Regions, the high-ranking officials with real power above the level of the six ministries also decided to continue to implement the policy of "from point to area" and "business focus".

As a result, Zhang De spread out the map of the South China Sea and found that the Tang Dynasty forces, either like nails or rice cakes, were clinging to each other and never left the key advantageous areas.

This is the dual result of the imperial court's policy and the people's will, even if Zhang De feels that it is unbelievable and incomprehensible, it really happens like this and continues to spread.

"It's really a little sleepy, and I have a pillow."

After thinking about it several times, Lao Zhang, at his desk, remembered the current Tianzhu Civil War, and the Western Turks "exchanging slaves for slaves", and couldn't help but feel a little emotional.
