But that was just a normal situation, according to Zhang San's plan, four or five years later, Ryukyu would launch a campaign against the Song Dynasty to occupy the Hebei region of Shandong, so Zhang San needed more soldiers, and he also needed to train more reserves.

Therefore, Zhang San plans to train 100,000 army reserves and 40,000 naval reserves every year, which is just right for the current soldiers to push and push in batches and enhance Zhang San's control over the Ryukyus.

Soldiers are a high-quality population resource, soldiers have received good discipline education in the army, team education, Zhang San also fought in the army literacy education, and the war has cultivated a strong and resolute character of soldiers, and has the courage to face problems, these are very excellent qualities.

Therefore, retired soldiers are often excellent grassroots personnel, whether they are arming local troops, militias, or serving as policemen, etc., they are all competent, and even if they are village chiefs and town heads, they can also implement the spiritual will of the kingdom well.

In particular, Zhang San wants to occupy new land, and these retired soldiers can lead immigrants to defend their land and resist all kinds of invasions, so the promotion of the reserve military service system will have more advantages than disadvantages.

Even if it costs a little more money Zhang San doesn't have it, but we can rob it, whoever has the money will rob whom, we can't afford to raise so many troops ourselves, we can rob it, just like the one who owes repairs like the Wa State, is beating up, and then getting a million slaves.

Then they can merge the north and the south, and after the merger, they don't need to feed so many troops by themselves, and as for the defense of the territory, they can completely hand over to the Ryukyu army, and then they only need to give Ryukyu 50,000 military expenses a year.

There are many other countries like this, such as the Goryeo Kingdom, which can support a lot of troops, and the Ryukyus are now in a period of great development, as long as this group of immigrants is digested, I believe that the national strength of the Ryukyus can be raised to a higher level.

Now start preparing Zhang San believes that in five years, he will definitely have the strength to fight with the Great Song Dynasty, it sounds like five years is a long time, but a lot of preparations will start now, even a year or two ago.

For example, food reserves, weapon reserves, and food naturally needless to say, why did ancient wars like to divide troops and count roads, and when they got it, didn't they know that it was more powerful to gather their fists together? This is also a logistical constraint.

In ancient times, the transportation capacity was only a few kinds of ships, donkey carts, and even rickshaws, and a cart of material transported from the rear to the front line often had to be consumed on the road, and the farther it was transported, the greater the consumption.

It is very simple to gather a million troops in one place, but if you want to transport the food of a million army to the front line, then it is impossible to reach the distance of increasing food, and an army of 100,000 people may need the output of a million people nearby to provide it.

But after 200,000 people, it will take the output of 3 million people to support, because the food of the extra 100,000 people needs to be transported from farther places, so in ancient times, it was also a need to share the logistical pressure by always liking to divide the army and march in multiple ways.

Just like Zhang San for this campaign, he mentioned that he had hoarded grain on Sea Shark Island for two years, and after the war, the ship-by-ship shipment to Yangzhou and other places occupied almost one-third of the transportation capacity, and later changed to local grain requisition, and the situation improved.

This still relies on the advantages of sea and river transportation, it is conceivable that if there is such a war in remote areas, the loss will be many times that of now, and the situation in Shandong is like this, although it can also rely on sea transportation, but hundreds of kilometers into the land is still inseparable from land transportation.

Zhang San is not an inexperienced novice, and the transportation business of Weiyuan Dart Bureau has accumulated experience in transportation for Zhang San over the years, so Zhang San estimates that the consumption of grain and grass in this war will be twice that of the Yangzhou Campaign.

And unlike the Yangzhou Campaign, this time it can't be like Yangzhou to collect grain on the spot, because Zhang San will not grab a handful and leave, and the people's grain will be requisitioned, what will the people eat?

Therefore, Zhang San had to store enough grain for two million people to eat for a year in Shandong within five years, but fortunately, Zhang San occupied all the rice producing areas that could be harvested three times a year.

However, the biggest headache for the Ryukyus next year will also be the food problem, the new immigrants need to open up the wasteland, during which they can only consume last year's grain stockpile, and Zhang San, who has delayed the harvest of the first season, needs to make it up from many aspects.

That's nearly five million people, and the food deficit is expected to reach more than 30 days, and this is if the army is not fighting, and if there is a war next year, the food shortage may increase.

This is also one of the reasons why Zhang San is so anxious to end the war, next year Zhang San will buy grain from Southeast Asian countries on a large scale, and then work hard to build new fishing boats.

In addition to the internal reasons in various aspects, there is also an important external reason, in recent years, the Western Xia has been pressed and beaten by the Great Song Dynasty, and Tong Guan and others plan to continue to brush their prestige from them, so the Western Xia plans to use the old method when they can't resist, and even Liao resists the Song Dynasty.

According to the intelligence, Western Xia was preparing to marry the Liao State in exchange for the support of the Liao State, and then the Liao State was also concentrating its forces to prepare to put pressure on the Great Song Dynasty from the north.

Therefore, in order not to cheapen these alien races, Zhang San resolutely made peace, and now the troops are being withdrawn one after another, and the withdrawn troops are also changing their equipment in the order in which they were established, and they want to complete a lot of preparations for the compulsory military service system.

First of all, the soldiers who have reached the length of service should be selected, and those who have served for four or five years are still small soldiers or captains, and this time they will be discharged, and after retirement, these people will be enriched into military stations in various places.

Then it was necessary to integrate the militia of the villages in various places, and the village militia was still a product of the early development of the Ryukyus, and at that time there were still wild people on the Ryukyu Island, and in order to defend against the wild people, each village set up its own militia.

Now don't say that Ryukyu is the Luzon region, there are very few savage villages, of course, there are always individual fish that slip through the net, but it can't affect the overall situation, and now the savages only have two ways to either surrender or die.

Those who surrender voluntarily can also get some of the same treatment as other villages, as for those who resist stubbornly, they are all caught and sent to the mines, and the next step is Borneo, anyway, there is no shortage of manpower in mining, and there are slaves everywhere to catch.

So now the militias of Luzon and Ryukyu can choose a group of excellent ones to be directly converted into reserves, and it just so happens that the next step in the development of Borneo is the battlefield to train them, and the regular army will be used to deal with the problems of Goryeo and the Wa Kingdom.

However, these will have to wait for a while, the first is the food problem, the second is that the new weapons and new tactics need to be trained, and the third is that it will take time to change the equipment, and it will take more than a year to complete the replacement of troops with the current production capacity of the Ryukyus.
