When the Jiangnan of the Great Song Dynasty was in full swing, the Chola War of the Ryukyu Army also entered a critical moment, and after the Chola capital was broken and the main force was destroyed, the three countries successively invested nearly 50,000 troops each, and finally completed the landing of the three locations.

According to the agreement, the Ryukyu army would not participate in the attack on Chola, and the three countries would freely share the spoils themselves, while the Ryukyus set their sights on the island of Sri Lanka, and now the Ryukyus want to occupy the Indian subcontinent is very laborious, and even occupy there for a short time and cannot afford to wage war against the Great Song Dynasty.

Therefore, Zhang San needs to have a series of strongholds and a logistics supply base there, with the island as the lock and the sea as the chain to lock the Indian subcontinent, and Sri Lanka is an important part of this plan.

Just like the United Kingdom, isolated from the mainland, stirring up the mainland, this place will have a unique advantage, although the position is so important in Zhang San's eyes, but Sri Lanka is just a big border island in the eyes of Chola, just like the Great Song Dynasty looks at Qiongzhou.

So the occupation here did not encounter any decent resistance at all, the only trouble was the disposal of the residents of the island, Zhang San decided to deal with it according to the original plan after thinking about it.

Occupying Sri Lanka, Zhang San is equivalent to opening up the waterway between the east and the west, as long as you go around the African continent, you can reach Europe, but now Europe is a poor and barbaric place, there is no need to trek through mountains and rivers to go there.

The central axis of this world is the East Asian part centered on the Great Song Dynasty, the Indian subcontinent, Central Asia, and the Mediterranean coast, and the civilizations of these places represent the whole world.

Therefore, the occupation of Sri Lanka also means that the Ryukyus have successfully opened up the sea route from the Great Song Dynasty to the Mediterranean, although there is no Suez Canal, but the Great Song Dynasty only needs to sell goods to the Red Sea coast, and naturally some people transfer goods to the Mediterranean.

Now it is the Byzantine Empire, that is, the Eastern Roman, that is, the Eastern Empire, that is, the Eastern Mediterranean, which is nothing more than a transshipment of goods and middlemen between the East and the West, and does not block the trade routes between the East and the West, so it is still possible for the Ryukyus to do business in the Mediterranean.

After opening up the Maritime Silk Road, then the Age of Discovery, which belongs to Ryukyu, has arrived, and the current land area of Ryukyu has spanned half the world, and it is only one step away from the empire on which the sun never sets in Zhang San's dream.

But when the Ryukyus hit Sri Lanka and occupied it, Zhang San felt that his expansion seemed to have reached a new bottleneck, not because the army could not go, but because the newly occupied places could not be digested.

From the Great Song Dynasty to Sri Lanka, it was necessary to cross the East China Sea, the South China Sea, the Strait of Malacca, and cross a small half of the Indian Ocean to finally arrive, which was more than 10,000 miles, which was too far for immigrants and too far for Zhang San.

So at this point, Zhang San's road to external expansion is over, at least in the short term, he will not launch a war for external expansion, so Zhang San began to turn his eyes back to the Great Song Dynasty, and it is time to start being the master of this continent.

After the occupation of Sri Lanka by the Ryukyu Army, the three countries had a good time in Chola territory, but the distance between the two places was too long, and the three countries had no territorial claims to Chola, and after the invasion of Chola by the armies of other countries, the three countries began to plan to return home.

The materials looted by the three countries this time were sold to the Ryukyus nearby, and then they bought supplies from the north of the Ryukyus, and the three countries not only repaid the loans of the Ryukyus, but also purchased new food and weapons, and their strength quickly recovered, but the dead people could not be born in a short time.

Although the king managed to escape, he had many enemies, and after the retreat of the Three Kingdoms, the invasion of the enemy countries and the rebellions in various places reduced the territory of Chola to less than one-fifth of its original size, and it could no longer pose a threat to the Ryukyus.

I have to say that North Vietnam's luck is super good, Zhang San's goal at the end of the Chola War this time was originally his, but who knew that the Great Song Dynasty was too hot, Zhang San no longer had such a small country as air traffic control, and put all his energy on the Great Song Dynasty.

This year, taking advantage of the fact that the Great Song Dynasty was busy dealing with Fang La, Zhang San had planted a lot of personnel and materials in Shandong, and at the end of the year, Zhang San sent an additional 50,000 troops to the Miaodao Islands area, preparing to quickly occupy the Shandong region when the time was ripe.

And Zhang San's so-called timing was the timing of Wang Qing's rebellion and attack Tokyo, but these peasant armies were really more cowardly than he imagined, and they were better than he imagined, so Wang Qing didn't fight Tokyo at all, and he didn't even get out of Huainan West Road.

In this year, the Ryukyus conscripted another 150,000 reservists, and the total population of Han Chinese exceeded 15 million, and the number of other slaves exceeded 20 million, but the manpower was still insufficient.

More than 4 million people are employed in the three major industries of the Ryukyus, namely shipbuilding, coinage, and military logistics, of which 1.5 million are employed in shipbuilding and related industries.

The minting industry should have added another 200,000 to the discovery of the copper mines on the island of New Guinea, to 1.2 million, and of course more than 800,000 slaves in this industry, and nearly 1 million personnel related to the army's logistics.

Although the total number of the navy and army in the Ryukyus is only about 500,000, the population serving this army is more than 1 million, and with the employment of other industrial enterprises, more than half of the people in the whole Ryukyus work in cities or factories, and the fields are either large areas of slaves, or old and weak women and children.

This is also the reason why the vast territory occupied by the Ryukyus is always plagued by food problems, and the lack of enough people to cultivate the land is always a big problem, and the only way to solve this problem is to get more people to farm.

Moreover, the vast territory of the Han people is not the dominant ethnic group, and there is even only one Han settlement in many areas, although Zhang San has been trying to clear it, but there are still millions of indigenous people in the places that Zhang San did not take into account and the undeveloped places.

Zhang San can only take the method of arresting and clearing at the same time, but now more and more slaves are used in the Ryukyus, and slaves have begun to penetrate into all walks of life in the Ryukyus, from mining to farming, from fishing to grazing, and even many workshops in the city have begun to use cheap slaves to work.

In this way, for a long time, if there was a slave rebellion, the harm would be greater than before, so Zhang San needed more Han people to enrich the places, and the Han people only had the Great Song Dynasty, and there were many of them.

So when Zhang San set his sights on the Great Song Dynasty, the entire Ryukyu war machine was started again, and next year was preparing for a year, it was time to attack the Great Song Dynasty, and Zhang San had waited too long for this day, and many people had waited too long.
