Empress Changsun went back with Jinyang, of course, she took the Princess Changle, in fact, when they came, Li Shimin thought that he would also come to Dahan in the middle to take a look and see what kind of difference there was from nine years ago, but he still didn't have a chance.

The main reason is that Li Tai's movements are too fast, or they don't think about what kind of blow this series of actions will be to the Japanese country.

Donglin Island has a population of only 400,000, and the young and middle-aged people are only about 100,000, which is only about 50,000 or 60,000 people, but in just a few months, Li Tai organized and trained 15,000 Donglin native troops.

All of them are composed of Japanese people, their training is not backward at all, they are all in accordance with the model that Li Tai and they learned in the Han Dynasty, the army training method of the Han Dynasty is completely different from the army of this era, but this kind of training method, especially the training in internal affairs, has an absolute advantage.

More than 1,000 years later, there are so many countries in the world, but all military powers must grasp one thing in the internal affairs of the army, such as the domestic tofu blocks, including the US military, which everyone thinks is lazy, and there are places that they absolutely require in terms of internal affairs.

In fact, the effect of these measures is the same, that is, the training of soldiers.

Li Tai and the others want to analyze such a result, so Li Tai naturally started to implement such a strategy directly on Donglin Island, and the transfer of so many young people is a huge pressure for a country with a population of 400,000, but it doesn't matter for Donglin Island, because they have logistical supplies.

The grain from Datang, oh no, to be precise, the grain from Dahan allows them to completely ignore the impact of these people on the land and other aspects, so the situation on Donglin Island has improved rapidly, and Li Tai's reputation on Donglin Island has reached its peak in more than half a year.

What Wa Kingdom? All the ordinary people on the eastern island don't care at all, as for those nobles...... They want to return to their previous state, but they also know that it is impossible, and they know that it is impossible, so no one likes to look for death, not to mention that Li Tai also gave them enough profits.

For example, let them operate the goods transported by the Tang Dynasty, these goods Li Tai did not operate by himself, but handed them over to some of these nobles, because they knew more about the nobles opposite, and Li Tai only had one request, to earn more gold.

Although the Wa State is a country that lacks resources, but the Wa State has a lot of gold mines and silver, so the ratio of gold and silver in their country is actually very low, at least much lower than that of the Tang Dynasty, and there are naturally not many things that silver and gold can buy as currency in their country.

And according to the words of later generations, this exchange rate alone has several times the profit, not to mention the goods themselves, in just half a year, Li Tai has gathered a huge amount of wealth, of which gold alone earned nearly fifty tons!

It's only been a few months? Fifty tons of gold is already a huge amount for the Wa Kingdom, and Li Tai's trade has single-handedly increased the proportion of gold exchanged for silver in the remaining national capitals of the Wa Kingdom.

However, according to their statistics, it is estimated that there are more than 1,000 tons of gold reserves in the Wa Kingdom.

More than 1,000 years later, about 200,000 tons of gold have been mined in the world, but this figure is inaccurate, because gold has been mined for too long in human history, no one knows how long it has been mined, and there are many countries whose gold reserves are not publicly available.

Because of its unique characteristics, gold has always been used by human beings, such as ancient Rome and even ancient Egypt, and gold mined in ancient Egypt may be used more than a thousand years later, but it is nothing more than a higher purity.

In fact, the amount of gold mined in ancient times is not a lot at all, it is estimated that there are at least tens of thousands of tons of gold in the world, and the gold mines in the Japanese country are actually not a lot, and the silver is even more, but these things are actually according to the teacher to them, the really huge output has not been discovered, and now the ones that have been found are some small production.

So much for the small production? Not to mention those huge yields?

In fact, the total amount of gold in the Japanese is about 100 tons, which is the approximate estimate of Li Tai, because they have been buying gold all the time, and the people on those islands have to use gold to pay for things.

Therefore, their domestic gold has been flowing out, and some of the things they can sell to Li Tai are not of high value, but they are more willing to let Li Tai use Datang's goods to offset their accounts, thinking that these goods can bring them more profits.

On the whole, gold and silver naturally flowed out, but what made Li Tai even happier was that the base currency used by the Wa Kingdom was actually the copper coins of the Tang Dynasty...... This is really wonderful, yes, there was no currency before the Wa Kingdom, and it was all bartered or directly replaced by grain and cloth.

Their gold and silver are actually used to make offerings to Datang, and now that Li Tai is trading with them, they naturally accept barter, or accept copper coins, which is simply beautiful for Datang.

Datang's copper coins are not how many are there for Li Tai? Copper ore is a problem for Datang, but it is not a problem for Dahan, in fact, after Datang used the silver tickets in the money bank on a large scale instead of the currency of large-scale transactions, almost all the copper coins that Datang originally stacked in the major families have flowed into the Datang bank.

And these copper coins are almost useless, because the silver tickets can already be directly circulated, so these copper coins Li Tai does not mind being directly transported to the Wa Kingdom.

It is used in exchange for gold and silver, and the Tang Dynasty also uses gold to buy things and the Han Dynasty anyway.

In addition to these most basic trades, Li Tai also developed another trade, a trade that should not have been here, and that was the slave trade. Slaves were supposed to be strictly forbidden to be exterminated by Li Tai, but this was also a time of trade, and the person who traded with the other party on behalf of Li Tai suddenly came back to report to Li Tai that the person didn't have so many things, and he couldn't exchange slaves for trade.

There was a similar trade in the Wa Kingdom before, and they themselves were used to it, but Li Tai was in contact for the first time, and when he heard the news, Li Tai was naturally overjoyed, does this still need to be thought? Of course it changed!

Now Li Taike is very clear that population is the greatest wealth.

So during this time, Li Tai has been buying a large number of slaves, and after these people bought them back, they were naturally directly relieved of their slave status by Li Tai, so they naturally hurried Li Tai, and because Li Tai didn't care about the size of the man, both men and women, for most of the year, Li Tai bought almost 100,000 slaves.

He was a little skeptical, if he continued to buy, would he be able to buy out the Japanese country?

But in fact, the number of purchases is basically the limit, and the nobles next door are not stupid, and there is no one to work for them if they are sold.

Nanikawa Hakata actually has an idea, that is, to provoke those nobles to fight with each other, as long as they fight with each other, the plundered slaves will naturally be sold if they can't solve the problem.

However, this policy was directly rejected by Li Tai for no other reason, because Li Tai did not want to continue to implement his previous policy.

The main thing is that Li Tai thought too much before, he thought that the more than 10,000 soldiers in his hands could not rule the Wa Kingdom, but in the past half a year, Li Tai has found his next direction, that is, the Wa Kingdom is too weak.

There were only 10,000 soldiers in the entire Wa Kingdom, and there were 4,000 soldiers scattered among the different nobles throughout the country, and only 6,000 belonged to the emperor.

Second, as the people under Li Tai continued to trade with the Japanese state, and Li Tai did not prohibit others from entering Donglin Island, because Li Tai has always pursued a policy, that is, if his life here is good enough, some people will take refuge, as long as there are more people to take refuge here, there will be fewer people on the other side.

It's like what his teacher did in the early stage, so he didn't refuse to come, and even came to him, made sure that he was in good condition here, and ran back to call people, and he also gave him the travel fee.

The Wa Kingdom itself is not big, which has led to Li Tai's reputation having resounded throughout the Wa Kingdom, which is why he trained the Wa soldiers because he was ready to do it directly. Since it can be solved in a devastating way, he still plays a fart farming management policy.

Therefore, because Li Tai's progress is too fast, Li Shimin is too busy to have time to come to Dahan, he has always paid attention to this matter, not only him, Li Ke and Li Chengqian actually ran to Donglin Island, and the two of them came purely for the side, and to help solve some troubles by the way.

The Wa Kingdom is so weak here, such as the real wax, the mule country and a large number of places are not much better than the Wa country, such as what Li Ke is going to go, that is, the Philippines in later generations, Indonesia and other islands are mainly indigenous, basically primitive society.

So they have to learn some experience, in fact, the main thing to learn is Li Chengqian, Li Ke has to learn much, more of his people there are indigenous, Li Ke's main goal in the future is the immigration of the Tang Dynasty.

Less than a week after Empress Changsun returned to Datang, Li Tai, who was located on Donglin Island, finally made a decision to march!

Of course, this time Li Tai is also looking for an excuse, anyway, there are so many people who trade with him every day, who provokes him is very simple, this is just an excuse, more importantly, he has a lot of slaves who sneak over from the opposite side every day, these people sneak over, and after thinking that this place is good, they want to secretly run back to bring their relatives and friends, or their families.

Because many people come by themselves when they run over, the old and weak must have no way to run over, so when they go back, it is naturally risky, in fact, when they go back, as long as they say that they are Li Tai's people, no one rushes to stop them, but there are always so blind.

Li Tai naturally has an excuse.

However, before marching, Li Tai announced the news to all the people in his entire territory, and he went under the slogan of saving the slaves, which can be imagined...... Everyone in Li Tai's entire territory was boiling, and they all enthusiastically supported Li Tai.

And these are just the effects that Li Tai has achieved in more than half a year, this time there are only about 3,000 Tang soldiers, plus 12,000 Japanese soldiers trained by Li Tai, and these Japanese soldiers are all wearing the cotton clothes, armor, and related weapons given to them by Li Tai.

The Tang fleet did only one thing in the strait in the northeast corner of Hakata Castle, transporting soldiers over.

The reason why there were 3,000 Tang soldiers was because Li Tai wanted to follow them, and similarly, these generals of the Tang Dynasty were also in command of these Japanese soldiers.

The emperor who suddenly went to war was unexpected, and although Li Tai reported to Li Shimin, Li Shimin did not give him any advice, but let him decide for himself. The reason why Li Tai chose to attack in winter is also very simple, the Japanese lack cotton clothes, and their combat effectiveness in winter is far worse than them.

Related news, Li Shimin also sent a copy to Huo Gang, in fact, Li Tai's progress was faster than everyone imagined.

In the eleventh year of the Han Dynasty and the eleventh year of Zhenguan, not long after the spring, Li Tai had already driven straight in, almost approaching Nambakyo in the Wa Kingdom.

He barely encountered any decent resistance, and there were not many soldiers who were close to him, and more importantly, ...... These soldiers did not have much incentive to resist, Li Tai's reputation was too high, and these slaves of the Wa Kingdom knew Li Tai's reputation.

Especially when Li Tai built a place, he freed all the slaves, and distributed them the grain that originally belonged to the nobles, and allocated them houses and fields, almost all the slaves went crazy.

And such news swept almost the entire Wa Kingdom under Li Tai's deliberate instructions, so in just over two months, Li Tai had already pushed outside the Namba capital of the Wa Kingdom, and he did not encounter any resistance at all before this time, and many places almost surrendered directly.

There were some nobles who didn't want to surrender and surrendered directly without hesitation after seeing the 10,000 heavily armed army, and there was no way to fight at all.

By the time they advanced here, the population under Li Tai's command was close to one million, almost half of the population of the Wa Kingdom.

Because the winter climate gets colder the further north you go, the population is not large.

To be honest, even Li Tai didn't expect him to advance so quickly, and the important thing is that because of his prestige, these lands he shot down don't need too many people to govern at all! Just after dividing the land, let them wait where they are, these Japanese people are extremely well-behaved!

To be honest, Li Tai felt it for the first time, after winning the hearts of the people, the speed of pushing a country is too much, no wonder his teacher Dahan has developed and grown so fast.
