Not only ships and ocean-going trade, but many industries on the island of Ryukyu were gradually opening up to private businesses, with priority given to merchants who followed in his footsteps.

For example, kiln factories, brick factories, tea mountains, mulberry gardens, etc., these industries were originally established for the construction of Ryukyu Zhang San was established easily, these facilities occupy a lot of manpower and material resources and management talents, and do not make much money, so Zhang San is ready to open all to private individuals.

In particular, the construction of tea plantations is the top priority, because the Great Song Dynasty has issued an order to change the tea of the entire Great Song Dynasty to be changed to official management in order to increase income, so the purchase of tea from the Great Song Dynasty in the future is not only expensive, but also does not necessarily guarantee the quality.

Fortunately, Zhang San has established a lot of tea mountains, and although the trees are still small, they can harvest a little. The Great Song Dynasty did not force it because of Zhang San, before Zhang San hit Yangzhou, the Great Song Dynasty had already ordered the tea franchise.

Shops on the street in Tamsui City and other cities were also allowed to trade, and various orchards and spice gardens were also opened, and in order to encourage more people to develop Luzon and Borneo, Zhang San also rented some of the plantations he had built to the Ryukyu Islanders at a low price.

Zhang San even considered opening some coal mines and iron mines to private individuals, but now there are not many mines discovered, and there are no more mines for private individuals, so these things have not been opened for the time being.

In addition to these, Zhang San is also studying the army's adjustment plan, although Zhang San has considered not having an establishment above the regimental level, lest the general's power be too great, but there is a real problem, that is, the current scope of control is too large, and there are really problems with the regiment-level units that cannot solve them.

The most typical is the Wakoku area, in case of a Wakoku riot, a group of 5,000 people is still relatively reluctant, and it is too far away from the Ryukyus, even if it is used to use carrier pigeons to deliver news and make a round trip of about five days.

Referring to the systems of other countries, Zhang San decided to establish the post of governor and grant wartime command, of course, this right needs to be reported to the Ryukyus.

In addition to the governor of Zhenwei, the next step is to set up the governor of Goryeo and the governor of North Vietnam, as well as the governor of Malacca in the future, etc., this first governor, Zhang San is ready to use Yang Tai, the first is that he is more loyal, the second is that he has this prestige, and the third is that he has this ability.

After Yang Tai left, the Praetorian Guard was expanded into three regiments, and the command was also divided into three, with Luda as the head of the army regiment, Zhao Yunlong as the commander of the cavalry regiment, and Li Jun as the commander of the Praetorian Fleet.

Originally, Zhang San planned to withdraw from the Great Song Dynasty, and immediately began to sort out the Wa Kingdom, but because of the food problem, he had to settle down for a year, so only two regiments were placed on the town of Wa Island.

These two regiments also had to assist the Northern Fleet in setting up a supply depot in Beihai Province, Beihai Province is Hokkaido, where there were originally some Ezo people who are now all used as slaves, and the reason why Zhang San attaches so much importance to this island is also for horses.

In order to prevent these people from escaping to Hokkaido, Zhang San sent ships to block the strait between Hokkaido and Honshu Island.

Later, Yanqing went deep into Mongolia and successfully established a trade channel by Hulun Lake, but if Zhang San wanted to transport Mongolian horses out of the Mongolian steppe, then he had to rely on the water transportation power of Heilongjiang.

Although Heilongjiang is frozen for several months of the year, in order to get more war horses, even if there is only a glimmer of hope, Zhang San has to fight hard, and from Hulun Lake downstream, Heilongjiang flows all the way northeast into the northern part of Sakhalin Island.

It takes seven or eight days to walk in this river, so Zhang San needs to build horse farms in the north of Sakhalin Island and Hokkaido to restore the physical strength of the horses, and the climate in Hokkaido is very suitable for the survival of Mongolian horses, so Zhang San simply changed Hokkaido Island to Beihai Province to build a horse farm.

Opposite Beihai Province is the Jurchen hinterland, if he dares to stab the Jurchen one day, Zhang San can directly send troops from Hokkaido to smash his nest, and the next step is to establish a horse farm on Jeju Island, you can control Goryeo, Liaodong, Hebei, Shandong and other large areas.

However, it is really not suitable to establish a base on Sakhalin Island in this season, so it is necessary to set up a dock warehouse in Hokkaido first, one is to prepare for the opening of trade routes north after the beginning of spring, and the other is to supply supplies for the passing exploration fleet.

Yan Qing is indeed a very good diplomatic talent, since he went to the north, just by virtue of one mouth, he has established trade relations with several tribes, relying on Lu Junyi's matchmaking, Yan Qing has actually obtained more than 5,000 horses from those tribes.

Coupled with the more than 2,000 horses that Lu Junyi helped to get, this not only allowed the cavalry of the Ryukyus to be expanded, but also the horses of the artillery unit were replenished, and at least 20,000 good horses could be provided in these places next year.

After the army returned to the Ryukyus, in addition to the two regiments stationed in the direction of the Wa Kingdom, one regiment was left in Zhoushan and Miaodao, four regiments were left in Luzon, and eight regiments were sent to Borneo, so that there were 80,000 men.

On the main island of the Ryukyus, there are also three regiments of the Praetorian Guard, as well as six new regiments and 32 battalions of conscripts, who are sent to Borneo for actual combat training after three months of recruit training.

In addition to the issue of setting up a governor, the current military reform is also a question of the organization of these conscripts, and all units do not like to use new soldiers, especially those who will be discharged after a few years of service; in everyone's opinion, this kind of soldier receives a batch every year, so it is not bad if the combat effectiveness of the troops is not to be improved, not to be reduced.

But in fact, the first few batches of conscripts could not be discharged, and when the first batch was discharged, it was estimated that it would be just in time for the Shandong Campaign, and it was estimated that they would be pulled to the front line at that time, but Zhang San could not tell the news, and at present this plan was still confidential, and it was difficult to guarantee that it would be leaked.

Therefore, Zhang San hoped that all regiments would accept a batch of such conscripts this time, not only to receive, but also to lead these soldiers well, and train these soldiers into strong troops, but judging from the news fed back from Borneo during this period of time, the performance of the conscripts was not ideal.

These conscripts fought in Borneo as battalions, but the various units did use these conscripts as coolies, either to clean up the battlefield, or to build camps and defend camps. Either it is used to transport grain and grass.

This is completely ineffective in training, so this is also the purpose of Zhang San's reform of the military system, and this method of conscription and recruitment into battalions is undesirable, so Zhang San plans to adopt a new organization method.
