Since Zhang San put forward this demand, the General Staff immediately began to formulate specific regulations for attacking the Japanese, first of all, the transfer of ships, and the selection of the Japanese naval division for the First World War, this time a total of 120 warships were to be transferred.

There were also 20,000 marines and 20,000 army troops, and this war was also a rehearsal for the Song war, so the various units immediately set off to assemble on the northern island of Xiaoliuqiu, and the port of Naha was immediately lively.

After the final study of this operation, the preparation time was two months, and the combat time was three months, and in the later stage, it was necessary to continue to put pressure on a fleet of about 40 ships, and if the Song war was urgent, this fleet could also be temporarily transferred.

Shi Jin and Wu Song were both assigned to the attacking force as battalion commanders this time, Zhang Yuanba was also equipped with new armor and received an order to kill people at will, and a month later Zhang San arrived at Naha Port, by which time the ships had completed their assembly and intelligence gathering was being carried out in an orderly manner.

The materials are also being transported to the ports along the way according to the scheduled plan, and the Marine Corps and the Army units are also training together in Tamsui City, and the Ryukyu Army has not fought the enemy with more than 1,000 people since its establishment, so the troops drawn by Zhang San this time are very nervous, so Zhang San asked them to conduct some offensive and defensive drills.

Of course, Zhang Sanyi is still a super master in his hand, as the saying goes, a soldier is a bear, and a nest of bears will be bears. With this group of fierce generals under the leadership, it will definitely be able to play the momentum of the Ryukyu Army, and the strong army has always been not trained only by training, it is fought by winning one victory after another.

The rattan armor of the navy and the plate armor of the army must be acquainted with the bamboo armor of the Japanese country, and the spears of Zhang San's attack troops were specially changed to hardwood poles in order to cope with the chopping of the Japanese swords, and the captains of the team were also equipped with a new type of wolf milling.

This is said to be a sharp weapon to restrain the Japanese invaders, and the Japanese army uses the Japanese sword as the main weapon, and the tactics are also based on the Japanese sword, so as long as their Japanese sword is restrained, the spearmen and crossbowmen in the back can easily win.

Half a month later, the Marines and Army Corps sailed out of the port and headed to Naha for three days of rest before setting off. The naval warships officially left the port to kill the Japanese state, and there was no war letter to declare war, and Zhang San's fleet was divided into six teams of twenty ships and went to different areas when it reached the foreign sea of the Japanese state.

One of the six warbands circled the Wakuni from the west, one circumnavigated the Wakuni from the east, and two circled the islands of Kyushu and Shikoku respectively, and the last two entered the Wakoku Sea from the east and west to attack the coastal ports.

At this time, there were no big ships in the ports of the Wa Kingdom, and the sampans were also the main ones in the sailors, and a sailing ship of several hundred stones was a great warship, and the Wa Kingdom had not been invaded since ancient times, so there was no such concept of defense.

Therefore, when the fleet of the Ryukyus lit the six largest ports of the Wa Kingdom into torches, the Wa Kingdom did not react for a moment, and then all the ports with ships were taken care of, and for a time the Wa Kingdom was full of warning signals, and there was no peace in the whole country.

However, it is true that the naval division could not be established in a day or two, and the Wa Kingdom wanted to strengthen the city defenses to deal with bandits, but many of the cities of the Wa Kingdom were built by the sea and water, and if the army and marines did not arrive, the walls of these so-called cities would have been broken by a few projectiles.

Five days later, the Ryukyu fleet completely cut off the connection between Kyushu and Shikoku from Honshu, and the army began to land on Kyushu, and the cities of Kyushu could not organize any decent resistance, and often a battalion could capture a so-called city.

The Japanese kingdom was not rich without developing silver mines, and these cities often had a population of only 1,200, which was only the size of a larger town in the Great Song Dynasty.

Therefore, when the resistance in Kyushu was completely eliminated, the arrest of slaves became an orderly manhunt, and all people under the age of forty-five and over ten years old were arrested and transported to various mines and farms.

Then the rest of the old people and children were sent to Honshu to be disposed of by the Japanese government, and Zhang San's goal was to first clean up all the Japanese people on Kyushu Island, and then return to relocate a part of the population from the Great Song Dynasty.

Kyushu Island will also be renamed Zhenwa Island, the original Japanese people on Kyushu Island are about 2 million, young and middle-aged people have captured 1.3 million, hundreds of thousands of old and young people have taken more than a month to transport, as for the young and middle-aged slaves can only be slowly transported away in batches.

However, there is still a lot of work to be done on Zhenwa Island, such as building a wharf, building a military port, tidying up farmland and water conservancy facilities, and so on.

However, it is a pity that the sea-crossing operation without the right to control the sea is just to deliver food, when the Japanese state crossed more than 10,000 people, Zhang San began to cut off the sea route, and the more than 10,000 people who crossed became the army and marines sparring partners.

After this time, the Wa Kingdom seemed to be much more honest and tried to send people to contact the Ryukyu Fleet, but Zhang San was not prepared to negotiate with the Wa State now, and with the character of the Wa State, he could only subdue them if they lost their temper and surrendered.

Seeing that the contact was useless, the Wa Kingdom immediately began to recruit troops, and a defense force of 100,000 people was formed on Shikoku Island, and a standing army of 400,000 people was formed on Honshu Island, and Zhang San tightened the blockade of the sea route.

As for the powerful army of the Japanese State, Zhang San felt that as long as it dragged on, as long as Zhang San continued to attack the coastal areas of the Japanese State and create strong pressure on him, then after a long time, the huge military expenditure would naturally drag down the Japanese State, and these armies would naturally collapse without a fight.

A month later, as the rebellion on Zhenwei Island was extinguished and half of the effort was carried away, Zhang San began to have the spare energy to set his sights on other places, the Wa country has a large area of mountains and forests, so it is not easy to destroy his shipbuilding ability.

However, the Wa State had no experience in building large ships, and as long as Zhang San strengthened the inspection of the coast, there were also navigable sections of some large rivers, and as for the more upstream areas, they were only suitable for making sampans.

The sampan was not much of a threat to the running warship, because Zhang San didn't know what to do with the sampan if there were ballistae and bed crossbows, as well as grenades and hand-held incendiary bombs.

In order to keep the nerves tense at all times, Zhang San began to send ships to attack and harass coastal towns, anyway, he only picked those weak defenses to attack, and withdrew in two days regardless of whether it was successful or not.

After a few times, the Japanese army also came up with a solution, that is, to divide the army into two parts, with 200,000 people stationed in Kyoto and the remaining 200,000 troops stationed in five parts.

This made the actions of the Ryukyu Navy constrained, and Zhang San felt that it was necessary to plan a big operation to make the Japanese kingdom remember it for a long time, so Zhang San used carrier pigeons to send an order to the Ryukyus to transfer another 20,000 marines to the Ryukyu, and the newly formed cavalry unit was also transferred.
