Cen Xiaonian really lived up to his expectations, and it only took a month to clear the pirates on the islands off the mouth of the Yangtze River and the Qiantang River.

Yang Huairen didn't know whether to be happy or angry, since he could wipe out the pirates at sea in a month, what did Cen Xiaonian do for so many years ago?

Pirates are definitely not as strong as they imagined, and the common people boast so much because the government has never been serious about suppressing them.

What is the combat power of the Changguo Army, Yang Huairen has seen it, there are forty or fifty small broken ships, and it is really impossible to think of a powerful naval army.

Looking at the pirate ships they captured, they were even more broken, as if they were about to fall apart when the wind blew, and it seemed that this group of pirates was like that.

That's the way it is in this world, sometimes things that sound scary, behind the veil of mystery, there is actually nothing real.

In the future, after the Japanese pirates and the pirates off the coast of China joined forces, they developed into a powerful pirate group, and now they are just a group of rogues who support small broken ships at sea and rob them.

Yang Huairen has now eliminated this group of pirates who have not yet become a climate, even if it is a matter of prevention.

Yang Huairen was not very interested in these things, and later Cen Xiaonian reported to him on the official affairs of the maritime administration and sent some maritime maps of the Great Song Dynasty at that time, which made Yang Huairen suddenly interested.

At this time, the sea administration will not really go deep into the ocean, but sail in the near sea not far from the land, on the one hand, the quality and sturdiness of the ship determine that it cannot resist too much wind and waves on the sea.

The second is that the size of the ship also determines that even if it is a sea ship, it needs to constantly go to land to replenish fresh water and food, and it is very dangerous to be too far away from land.

Therefore, the sea ships departing from Jiangyin Port sailed south along the coastline of the entire southeast coast of the Great Song Dynasty, sending valuables such as porcelain and silk from the Great Song Dynasty to Southeast Asian countries, and then bringing back local gold, spices, timber, and precious stones.

Yang Huairen looked all the way south along the schematic diagram of the route, and the route passed through the Qiongzhou Strait to the west, which was the Yue Li Dynasty, which was a more official name, and ordinary people called them Jiaozhi.

Jiaozhi is a contemptuous name for the barbarians living in this place by the ancient Han people, believing that their feet can hook a large arc and adapt to the living habits of climbing trees, so they are considered to be similar to monkeys, so they are called Jiaozhi.

In the Han Dynasty, Jiaozhi was still a county of the Han Dynasty, and in the Tang Dynasty, it became a vassal state, and in the Song Dynasty, Emperor Taizu gave the king of Jiaozhi Li Gongyun the king of Jiaozhi County, and was officially listed as a vassal king.

Although Jiaozhi was still a vassal state of the Song Dynasty at this time, in fact, the Song Dynasty no longer had enough ability to control Jiaozhi, and the Jiaozhi State actually established an independent regime.

The merchant ships of the Song Dynasty would go south to Champa after being supplied from Danzhou, and then to the south were Chenla and Sri Buddha, but they did not pass by Jiaozhi.

After Yang Huairen asked, he learned that the Nanyang countries were very respectful and friendly to the merchants of the Great Song Dynasty, but the Jiaozhi Kingdom not only did not respect them very much, but even robbed the merchants of the Great Song Dynasty.

Although the Jiaozhi State was called a vassal state of the Great Song Dynasty, it did not regularly pay tribute to the Song Dynasty emperor in the past 20 years, and compared with other countries in Nanyang who came to the dynasty every year, the Jiaozhi State appeared arrogant.

When there is a difficulty, he will send an envoy to pay tribute once, and after defrauding the reward of the Great Song Dynasty, he will not come for several years, although the court is unhappy, but for this kind of barbarian state, he does not care too much.

Yang Huairen thought about it for a while, and suddenly felt that the Song Dynasty was too patient with Jiaozhi, which made them more and more arrogant.

Cen Xiaonian saw that Yang Huairen was angry, and he couldn't understand why the prince was concerned about his 108,000 miles away, just a strong consolation.

Yang Huairen scolded his mother, but in his heart, he suddenly found the joy of a new continent.

The country of Cochin was later the northern part of Vietnam, and it is said that this place is rich in products, and the most produced is rice.

The land of the Song Dynasty, except for Danzhou, was basically two crops a year, and one season of wheat and one season of millet were planted in the north, which was actually enough for the people to fill their stomachs.

In the Huainan and Jiangnan areas, rice is harvested twice a year, and the yield is obviously much more than that in the north, so it has become the main grain producing area of the Great Song Dynasty.

Further south, because the population is relatively sparse and the land is not developed enough, it is basically self-sufficient in food.

If the Great Song Dynasty could have a naval army, cooperate with the infantry army to occupy the Jiaozhi State, and re-turn Jiaozhi into Jiaozhou and incorporate it into the territory of the Great Song Dynasty, then the Great Song Dynasty would not only be able to produce a large amount of food every year, but also eliminate the threat of Jiaozhi to the south in the future.

In addition, the local rice varieties are excellent, not to mention the three crops a year, I heard that farmers do not have to work too hard to cultivate the land, and they do not need to pay attention to it after basically sowing, and they can naturally have a bumper harvest after three or four months.

The Champa rice cultivated in later generations came from Champa not far from Jiaozhi, and if this was the case, the local excellent rice varieties could be introduced to the Great Song Dynasty on a large scale.

Then, the large undeveloped hilly land in the south was popularized and cultivated, and the entire south was developed into the grain base of the Great Song Dynasty, and the north could also free up space to grow other vegetables or cash crops to enrich the material life of the people of the Great Song Dynasty.

Finally, there is another point, at that time, the fishery development of the Great Song Dynasty was very extensive, and the fish eaten by the people were still mainly freshwater fish in inland rivers, and the way was mainly fishing, and there was no large-scale fish farming.

The marine fishing industry is also relatively backward, and fishermen go out to sea to fish, not more than ten miles of coastline, and there are not so many marine fish that can be caught, and the output is average.

If the shipbuilding level of the Great Song Dynasty can be raised to a higher level by taking advantage of the conquest of Jiaozhi, not only can the Great Song Dynasty naval army have larger and stronger warships, but also can build fishing boats that are more suitable for fishing.

The fact that fishing boats can go to sea farther means that they can catch more and bigger fish, which is very beneficial to enriching the dining table of the people of the Great Song Dynasty.

Commercially, if there was a place in Jiaozhi as a transit, the maritime merchants of the Great Song Dynasty could also get greater convenience, sell and buy back more goods, and obtain greater profits, without having to give up profits to the Zhenla or Sri Buddhas in vain.

It is also important to note that the war could have a great positive effect on the reforms of the Great Song Dynasty, such as solving the problem of redundant officials.

Since ancient times, the purpose of reforms has been to achieve political clarity, strengthen centralization, and at the same time promote the progress of industry, agriculture and commerce, so as to achieve economic development.

But the current new policy of the imperial court is a bit superficial and cannot solve the real problem.

For example, the new policy could not solve the redundant affairs of court officials, and the establishment of more fictitious positions to vacate substantive positions for capable officials did not actually solve this problem, but caused the official system of the Great Song Dynasty to become more and more complex, and the problem of redundant officials became more and more serious.
