After everyone discussed how to deal with the 100,000 forbidden army of the Great Song Dynasty, several important strategists stayed behind to discuss the next strategic direction, whether the old question was to go south or north.

The victory of the Wa Kingdom greatly encouraged the confidence of the people, and the army faction, led by Yang Tae, Wang Yin, and others, believed that it was necessary to maintain the superiority of the north and focus the migration on the islands of Sikoku and Goryeo in the Wa Kingdom.

As for the aborigines of these places, they were used as slaves for the Ryukyus, and in the future they could establish advance bases here to restore the homeland of the Han and Tang dynasties, and the newly emerging Jurchens could also attack their flanks from here.

The naval faction, led by Gan Xingtai and Lehe, felt that they should control more shipping lanes, and control the shipping lanes of the entire Great Song Dynasty, Liao Kingdom, Goryeo and Wa Kingdom in the Ryukyus, bringing more than 30 million guan per year.

There is also an important place in the south called the Strait of Malacca, and as long as it is occupied, the Ryukyus can earn more than 50 million yuan a year from the tax revenue of ships alone, and the income from port trade and so on is even more considerable.

Moreover, to control a larger sea area, more warships are needed, and more warships and the navy needs to be further expanded, and there is no serious land-sea dispute in the Ryukyus, but Zhang San said in his lesson that the Han regime has always been a land-based country.

Zhang San said that the so-called land power type of country is mainly based on land, the army, and the control of the mainland, and the navy can only be regarded as a naval division and an appendage of the army.

Unlike the Ryukyus, when it was founded, it was based on islands, with a small territory, poor resources, limited species, and surrounded by the sea, and all resources and strategic space needed to be acquired from the sea, so the Ryukyus developed as a sea power-based country.

Then Zhang San also talked about it, and told these important generals about his Zhang San's theory of sea power, within the territory of China, there are many mountains, many people, and little farmland, and the Chinese population will continue to grow in the future, but how to solve the contradiction of limited land and more people and less land?

To the north is the plateau grassland, cold, with scarce precipitation, only suitable for grazing, and to the west is blocked by the alpine desert, and it is not suitable for large-scale cultivation for 5,000 miles to the west, so the surplus population needs new land settlement.

Combined with the reasons for the change of dynasty that Zhang San explained to you before, everyone instantly felt that they had a heavy responsibility on their shoulders, and those who originally felt that the way to force Han people to emigrate by robbing people was wrong! The inhuman voice disappeared in an instant.

Therefore, China needs long-term peace and stability, so China's sword must open the way for China's plow! So when this assertion was formed, these soldiers were full of lust for domination over the land they could cultivate and the new world.

The navy has an innate advantage over this operation, so the navy hopes to open up more territory, and the army has always been limited because the expansion scale of the navy has been limited, so the army hopes to expand the scale and solve the problem of the Great Song Dynasty first in considering external expansion.

Zhang San naturally has his own judgment on this, after this year's war, Ryukyu will have a honeymoon period of three to five years with the Great Song Dynasty, and in addition to repairing relations with the Great Song Dynasty in the past few years, Ryukyu will have to do a lot of things.

For example, to solve the resource dilemma of Ryukyu, the most discovered in Ryukyu is copper ore, and the coal mine is indeed only freshwater, and iron ore is found in Luzon, but there is no coal mine in Luzon for smelting.

With the current transportation capacity, it is a very uneconomical transaction to transport resources from one place to another for smelting. Even if it is mainly shipped, the cost of the same goods is half or twice as high as others, which is not only a waste of money but also a waste of human resources.

Therefore, Zhang San needs to find a new location for the operation of the coal and iron complex, such a place is either very close to the two mines, or the transportation is convenient, such a place Zhang San knows a lot, but unfortunately it is not needed.

Let's not talk about the Ruhr area, what Zhang San can remember now is only Anshan, Baotou, Panzhihua, etc. in China, which have nothing to do with Zhang San now, and Zhang San has no strength to operate.

In addition to the Liao and Song countries, Zhang San searched around the map and found only two suitable places, one is Goryeo, it is said that there is coal and iron in the north of Goryeo, and Sanpang has exported these ores to China.

But this will be the frontier position against the Jin State in the future, in case it is mined by itself, and the Jin State will come to grab it, isn't it the rhythm of going to war with them in advance? Besides, where the cold traffic conditions are not good, the main thing is cold!

There is also a place where there is coal and iron near Jiaozhi in North Vietnam, and think about Shilu in Hainan, where the iron ore taste must be good, North Vietnam is now ruled by the Li Dynasty, and the occupation of South Vietnam is hot, the national consumption is very strong, and it is not very strong, and more importantly, where is the homeland of the Han and Tang Dynasties, if Zhang San occupies it, it will be at least one step closer to Fanbanghua.

There is also the next stage of the war against Goryeo and the Wa Kingdom, Goryeo must be cleaned up, the slaves of the Stick Country have a brand advantage, and the Silla Maiden brand of the people was once a household name in the Tang Dynasty.

Captured all of them as daughters-in-law for his own soldiers, because Zhang San found that the last time he used a Japanese slave as a daughter-in-law, he was unanimously supported by the majority of officers and soldiers, so Zhang San decided to expand the scope of these options.

At that time, as long as Zhang San's soldiers can't find a wife, they can apply, and if the application is passed, they can send a wife and pick their own, and they can choose from the Wa Kingdom, Goryeo, North Vietnam, Luzon, Jurchen, Khitan, Mongolian, etc.

There is also the Wa State, the reason why there is still a fight against the Wa State, it is because after Zhang San and the analysis of the General Staff, the Wa State still needs to be further weakened, and the current two islands of the Wa State have a population of more than 8 million, which is very unfavorable to Zhang San's rule.

Therefore, when the war in the Great Song Dynasty ended, the Wa State still had to find an excuse to repair it, and it was best to reduce the population to less than three million, and the same was true for Goryeo, which needed to reduce the population.

It is best for Zhenwei Island and Shikoku Island to be included in Zhang San's system, and it is necessary to make the Han population in this area more than one million after decades of adjustment, so that it will eventually become a Han-dominated area after decades of adjustment.

Through the influence of education and culture, the Goryeo and Wakoku people were eventually turned into historical terms, so as to ensure the long-term peace and stability of the region, and of course, this process also provided a large number of slaves for the Ryukyus.

Recently, with the continuous southward transportation of the Japanese slaves, various places have reported that the Japanese slaves are much easier to manage than the monkeys in the south, not only working steadfastly, but also very obedient, and their brains are easy to use.

Therefore, in order to obtain such high-quality slaves, Zhang San also needs to continue to use troops in these places.
