After Zhang San inspected the copper mines in central Luzon, he suddenly found that he could now produce more than 80 million copper coins a year, which was almost equivalent to all the tax revenues of the Great Song Dynasty.

So Zhang San is very worried about the occurrence of inflation, so he has been thinking of a solution recently, and now there is no good way except to build more ships and spend money to buy back materials.

When attacking the capital of the northern country, Zhang San suddenly remembered an old post on the forum, saying that the Great Song Dynasty subconsciously used a currency war to bring down Liao and Jin, although Zhang San felt that it might be unreliable, but this did give Zhang San a solution to the problem.

Think about the United States in later generations, isn't it just relying on currency to harvest the world and let everyone pay for his economic problems, so Zhang San has been studying this issue recently, and now the copper coins of the Ryukyus have a high degree of recognition in the Great Song Dynasty, and the same recognition is also in other regions.

Zhang San likes this kind of behavior of using his own money to buy other people's things and strengthen himself, because the cost of Zhang San's copper coins is not large, and even Zhang San wants to make copper coins on a larger scale, and directly looks for copper mines in Chile, I believe that the copper output will be more than doubled at that time.

The war in Borneo ended so simply, Zhang San originally thought that the large-scale battle would last for two or three months, but it ended in less than half a month, and Zhang San didn't need to be too involved in the next thing.

Borneo has its own administrative team, so if Zhang San works on the island, it will be equivalent to a blind command, and Zhang San, who is idle, cannot go around to inspect, which will delay everyone's work.

If you go shopping, a few big men are not interesting, and there is nothing to visit in this broken place, Zhang San stayed for half a month, and when he saw that there was nothing to do, he returned to Ryukyu.

In order to effectively implement the theory of currency warfare, Zhang San returned to the Ryukyus and focused his attention on the Japanese Iwami, the first step was to strengthen the garrison there, and after the rotation training and expansion, Zhang San's disposable troops increased, and within a month Zhang San threw two regiments there.

On the naval side, Zhang also sent four new gunboats three years later, and Zhang San issued an order to inspect Zhenwei Island after April, and invited the two kings of the north and south of the Japanese Kingdom to watch the military parade on Zhenwei Island, and prepared to persuade the two countries to strike troops and negotiate peace.

Because the south relied on a strong population base and trade with the Ryukyus, it gradually gained the upper hand in the dispute, seeing this situation, Zhang San decided to participate in mediation, as long as the north and south were not reunified, then they would not have more energy to care about the forces outside the two sides.

Many have written about the forbearance that the Japanese people understand, and they like to be obedient on the surface and secretly accumulate strength to plot rebellion, since everyone thinks so, so Zhang San also hopes to prevent the other party.

At least now Zhang San does not want the Japanese state to involve too much of his energy, after the discussion of the General Staff, everyone feels that now an open Japanese state has no value in the strategy, and now the forcible occupation will outweigh the losses, it is better to divide the north and the south for this situation to make it more convenient for the Ryukyus to earn benefits.

As for the slave robbery, the shortage of human resources in the Ryukyus is not so obvious, but with the increase of goods, the sales market needs to be further developed, and it is better to use the army to occupy more markets than to send a large number of soldiers to maintain the order of the Japanese state.

Therefore, the General Staff vetoed Zhang San's plan to fight against the Japanese, and instead proposed a plan to attack Goryeo, Zhang San had already planned to abandon the Goryeo plan, but the General Staff did feel that the current closed environment and market in Goryeo greatly restricted the trade of the Ryukyus.

In addition, the Goryeo people were arrogant and xenophobic, and Ryukyu merchants were repeatedly discriminated against and treated unfairly in the local trade, and even when they negotiated with the local government, the government favored local merchants.

Therefore, the battle plan formulated by the General Staff was that the army would land from Incheon, and the navy would enter the Han River to attack Seoul and force the Goryeo monarchs to sign a treaty, otherwise Wang Yun would be released to support him in establishing another power in the south and splitting Goryeo.

Zhang San no longer remembers when the General Staff began to consider economic interests when they formulated the battle plan, perhaps because he repeatedly emphasized the importance of competing for Malacca with the Chola Kingdom, or because Zhang San arranged for them to study the theory of currency war.

Anyway, now the Ryukyu has been very capitalized through the explosive development of this period of time, and Zhang San is the largest capitalist in the Ryukyus, and many of the products in the Ryukyus are produced to meet the needs of other regions.

The sudden expansion of the population in the period before and after the Song War had absorbed some of the production capacity, but after a few months of adjustment, most of the factories and workshops had expanded a lot, so if new markets were not developed now, there might be overcapacity.

The campaign planned to mobilize 50,000 troops, the first part of the Bohai Fleet of the Navy and the first part of the Ryukyu Headquarters Fleet, and the campaign often lasted for a month, so that the reserves of Zhenwa Island were sufficient to maintain it.

Moreover, a month later, a batch of grain was harvested in the Ryukyus, which could be maintained even if the campaign was extended, and Zhang San of course supported such a plan, and just after reviewing the town of Wa Island, after giving the Wa Kingdom a deterrent, the Goryeo Campaign began.

In the second half of the year, after the first grain harvest of the Ryukyu immigrants, they were able to become self-sufficient, and the Ryukyu army was alive again. When the time comes, even if a full-scale war against Goryeo is launched, Zhang San will not be afraid.

In April, after Zhang San arranged the affairs on the island, he boarded the Ryukyu and headed for Zhenwa Island, where the kings of the north and south of the Wa Kingdom were also greeted at the dock in addition to the important generals on Zhenwa Island.

Because he was preparing to start the Goryeo War, this time he came with Zhang San with eight regiments of troops plus the Praetorian Guard, a total of 50,000 people, and the king of the north and south of the Wa Kingdom looked at the fleet that covered the sky and the sun, and behaved more deferentially.

After more than a year of construction, the port is now called Sasebo, and now it is called the port of Zhenwa, which can supply 20 ships to unload at a time, and the wharf can moor more than 1,000 ships.

Zhang San did not immediately meet the king of the Wa Kingdom when he arrived at the palace of Zhenwei Island, but first asked about the preparations for the military parade on the Zhenwei Island, as well as the war situation between the north and south of the Wa Kingdom.

Instead, Luan Tingyu was enabled, Luan Tingyu was first qualified, and he had served as the head of the cottage in Funiu Mountain many times, and he was careful and diligent, and his performance in a series of wars was also remarkable, Zhang San felt that he should be able to take on this big responsibility.

Luan Tingyu really did not disappoint Zhang San, during this period of time, he did a good job of managing Zhenwei Island, and the communication and coordination of the Yu Navy and Army were also in place, and he decisively attacked and arrested the head of the Matsushita family and others who tried to build a big ship in Kyoto Bay.
