Zhang San expects that the island will produce food rations for 200,000 people next year, and the scale of immigration next year will be at least 200,000, and the new workshops on the island are all for the islanders, and the only shipyard produces ships to equip Zhang San himself.

Therefore, Zhang San needs to make the island's industry profitable as soon as possible, otherwise Zhang San will not have time to enjoy the benefits of island development, and he may be dragged down, such as the sugarcane planting area opened up by Zhang San, which is for the next step of sugar production.

But before that, Zhang San now had the first income, that is, salt, and the sea water drying salt started in the second month, and Zhang San had no experience, but just found a depression from the sea that would accumulate water at high tide and fenced it off.

When the tide is high, the seawater is poured into the entrance and exit to be vigorously dried, and then the next high tide is filled with new seawater, and after one or twenty days of hard work, the salt is really dried, and then the production method is improved and the yield is increased.

The principle here is very simple, Zhang San vaguely remembers that there is a stepped salt drying method, that is, the salt pan is divided into blocks, the dried ones are merged, and the unit output is increased, and after two months of exploration, the output of sea salt has finally entered a state of steady growth.

After the large-scale salt production, it not only solved the islanders' salt eating, but also exchanged with the natives for buying quality, but an embarrassing thing happened, because Zhang San caught the slaves too hard in the early stage, so that there were no indigenous villages by the Tamsui River.

But it doesn't matter, Zhang San directly selected a group of Han people who had trade experience with the indigenous people on the original island to open up new trade routes, Zhang San did it with the mentality of making a little money, and the real money was indeed smuggled to the Great Song Dynasty.

After Zhang San mastered the salt drying method, the cost of salt production was reduced on a large scale, and as long as the next step was to contact the illegal salt dealers in the mainland, then he could obtain a stable market, not to mention that salt is also a maritime trade commodity.

Regardless of the fact that everyone is close to the sea, but not all places are suitable for salt production, and not all Divan will produce salt, not only the island natives, but also Goryeo and Wa have always imported a large amount of salt.

In three months, the new fishing boats designed by Zhang San in Hangzhou had been built, and the trawls had also been produced, and Zhang San planned to wait for the fishing boats to arrive, and start fishing and whaling near the Ryukyus.

In the past few months, Zhang San's entire energy has been focused on the development of Ryukyu Island, and a large number of personnel from Sea Shark Island have been transferred.

These people all got a share of the land on the island, as well as the marines and the soldiers and sailors on each ship, and Zhang San was also given a certain amount of land, and as long as he could write a letter to invite his relatives and friends to come to the island, in addition to his relatives and friends would get the land, the introducer would also get a land reward.

This is also the main way of personnel recruitment in recent times, some people who were originally fooled to Sea Shark Island have now got a share of the land, and they have also begun to take their families over, which further increases these people's sense of belonging to Zhang San's forces.

Of course, doing business is a long-term way, but if you want to make money quickly, you can make money. Then the Zhang family, who had been staring at it, could finally come in handy now. There is no great difficulty in robbing, the key is to enter and exit the waterways of Taihu Lake, if there are a large number of officers and soldiers on the road to round up, I am afraid it will be more troublesome to kill them.

Fortunately, Zhang San had already thought of a solution, so taking advantage of the arrival of the second batch of warships, Zhang San began to stabilize the current occupied area, dispatch elite personnel, and prepare for the next move.

A month later, the second batch of six warships that Zhang San had been waiting for finally arrived in the Ryukyus, and Zhang San immediately ordered the formation of three two-ship formations to begin to suppress the small groups of pirates on the outskirts of the Ryukyu Strait. And Zhang San also got on a warship and left the Ryukyus in the name of asking for suppression.

In fact, it was not so troublesome, but Zhang San made a small mistake at the beginning, which caused this consequence, when attacking Da Li Zhuang, Zhang San appointed Wang Jin as a law enforcement officer for fear of robbery and other things when soldiers entered the village.

This was originally nothing, but later the rapid expansion of the territory, the increase in personnel, Zhang San has not been replaced, and when Zhang San was ready to change, Wang Jin did this work hard, people had just been attached, Zhang San took his feelings seriously, and did not force him to return to the teaching position.

In addition to supervising the military law of the soldiers, Zhang San also made him a circuit judge in order to prevent conflicts between the islanders, and Wang Jin can also enforce the law impartially, but now Zhang San is going to do robbery, so it is not suitable to take him.

Not to mention bringing him, Zhang San didn't even dare to know that if this little sense of belonging that was finally established was lost because of this incident, it would be a loss. However, fortunately, in the name of clearing the pirates, Zhang San's elite transfer of 200 people still did not arouse any suspicion.

In addition to the two hundred elites, Zhang San also brought Zhang Yuanba, this humanoid crane must be indispensable, as for the generals, Zhang San transferred Du Bao, Wang Yin, Li Jun, Gan Xingtai, Wang Huan five people.

Several people converged in the sea off Hangzhou, and went to Hangzhou to get on the two 5,000-stone cargo ships prepared by the Weiyuan Dart Bureau and went to Taihu Lake, and came to Taihu Lake to meet the waiting time, Zhang San and others anchored behind a small island and began to wait quietly.

In the past few months, Zhang San has not only let Shi Qian Tan hear clearly about the deployment of Zhangjia Island, but also got acquainted with several groups of Taihu Lake water thieves, this time Zhang San's two boats and boatmen did not come over more than 500 people, these people are Zhang San's henchmen and elites, and it is impossible to use them to attack the island, so Zhang San intends to hand over the matter of attacking the island to these water thieves.

After Zhang San arrived, Shi Qian immediately began to spread the matter of the gold hidden on Taihu Island of the Zhang family to several Taihu Lake pirates, although everyone had heard about this matter for a long time, but the Zhang family was powerful and could not afford to provoke it before, and even now it is not something they can provoke.

It is also rumored on the rivers and lakes that this Zhangjia Island is like an iron wall, a defense that 10,000 people can't break, and how many good hands in the rivers and lakes are lost on the island, so there is a heart for the news of the time migration, but more is just dare to think about it.

Zhang San had long expected such a situation, so when this group of insects had no leader, among the many Taihu Lake thieves, Liu Sanye, who was selected by Shi Qian, played a role, Liu Sanye was qualified, the old prestige is high, the key is that he has a very good reputation for faith and righteousness on Taihu Lake, and he has a grudge against the Zhang family.

Of course, these are not enough for Liu Sanye to call on an army of water pirates, but a map of Zhangjia Island's defense and rumors of millions of silver in the island's silver inventory have made these water thieves have both the heart and the courage of thieves.
