There are two types of so-called special transport ships, one for the transport of livestock, and the other for the transport of slaves, both of which are now under construction in Luzon.

Livestock transport ships are now mainly used to transport cattle and horses, and now there is only one cow among the thirty households among the new immigrants, which is the result of Zhang San looting the entire Suzhou and Hangzhou regions, and none of them have been left behind.

Therefore, the productivity of the Ryukyus is still very low, and for farmers, if there are cattle, a farmer can cultivate 20 or 30 acres of land, but if there are no cattle, a family will not be able to cultivate 10 acres of land.

A cow can turn two to three acres a day, and then take three days to rest for a day, and it generally takes about a month for a farmer to receive the seeds, so farmers with cattle can easily plant these fields.

If there is no cattle, it is all about manpower to turn over the land, and if a person can turn over an acre of land a day, he is a well-known farmer, so the average person can at most do the husband and wife can turn over an acre of land a day.

People are much more fragile than cattle, you do this kind of work for three days is absolutely wasted, so do it and rest, a month is only more than ten acres of land, so cattle are the key to productivity, Zhang San wants to increase grain production One way is to get a lot of fertilizer, and the second is to get more cattle.

Fertilizer Zhang San now mainly relies on guano fertilizer, wherever guano is found, Zhang San will immediately send slaves to dig and sell to the islanders, on average the average yield of guano fertilizer per mu can increase the yield of at least 50%, so guano manure has always been in short supply.

With fertilizer, it can also speed up the ripening of the land, and in addition to transporting the original farmer's own, Zhang San is also making every effort to collect, but this is not easy, the first is that it is not easy to collect, and the second is that it is not easy to transport.

Zhang San built more than 100 livestock transport ships last year, which sounds like a lot, but it was needed everywhere from south to north, transporting horses from the north, and transporting cattle to Zhenwei Island, and during the Yangzhou Campaign, all the livestock transport ships were concentrated to transport the livestock raised by immigrants from the Suzhou and Hangzhou regions.

The economy of the Jiangnan region is still much better than that of the north, and more than 10 households have one ploughing cow, so Zhang San got 70,000 or 80,000 cattle from the entire south, and one boat can transport 200 to 300 heads.

This is only cattle, every household pigs, sheep, chickens, ducks, donkeys and other domestic animals, these are much more than cattle, so that there are still some pigs and sheep in the Zhoushan Islands have not been transported.

And Zhang San also wants to get a group of Arab horses from the Arab region back, so this time to build a larger livestock transport ship, Zhang San's purpose is also to see the construction of a new type of livestock transport ship.

Zhang San turned the ordinary transport ship, came to the dock area, this side is the launching outfitting, Zhang San boarded the nearest one, this kind of ship is designed according to the scale of 20,000 stones, the scale of 1,000 tons, in order to prevent livestock from being transported for a long time without activity space, a layer of horse racing track is specially set up under the deck.

Below is a two-story livestock barricade, in order to lower the center of gravity, there are few superstructures on the deck, most of the materials and personnel are below, in fact, the size of the Arabian horse is not very large and is not suitable for lifting, but since everyone says that the Arabian horse can improve the quality of the horse, Zhang San also did the same.

And to get over there the horses can also be pulled back and slowly cultivated, this is a long-term thing, sooner or later to do, early than late to do a good job, the new transport ship with the old ship can transport more than 1,000 horses at a time, so one or two trips a year.

Zhang San saw that the newly built transport ship was generally quite satisfied, because of the transport of livestock, priority was given to wind and wave protection, so the use of the Fu ship ship type, this time a total of three were built.

With the original three used together, the difference between this kind of ship and a merchant ship is that there is a certain amount of self-defense weapons, after all, the road is far away, even if the warship is sent to escort it, but it is still necessary to prevent accidents, so these ships are equipped with a certain amount of ballistas.

After reading it, Zhang San was still very satisfied with the ship, and then went to see the ship that transported slaves, as for why he wanted to build a special slave ship, it was also forced by the form, and now there are more and more slaves used in the Ryukyus, and ordinary merchant ships have repeatedly attacked merchant ship crews and slaves to escape.

Even slaves can destroy ships, last year there was a ship because of the slave mutiny, occupied the cabin, the crew locked the hatch, the ship was directly dismantled by the slaves and leaked, causing the ship to sink, and the entire ship of slaves died.

Therefore, Zhang San now needs to build a special slave ship, this kind of ship is still needed for at least one or two hundred years, and the demand is very large, so it is simply specially built, and the design concept of this slave ship is similar to the concept of transporting livestock.

The main thing is to prevent escape and ventilation, so the cabins under these slave ships are designed to be more like prisons, there is nothing in them that can be disassembled, and these slaves will definitely not be able to dismantle the ship by hand.

Ten Yunnu ships were built at a time, and one boat could transport 3,000 people, so that the monkeys of Borneo could be transported by this kind of ship when they were transported to the copper mine in the future, and in general, Zhang San was quite satisfied with the shipyard here.

After visiting the shipyard, Zhang San went to the naval barracks to see the training of the Luzon Navy, because the Luzon Navy basically had no foreign enemies, so the scale was not large, and there was only one gunboat, and ten old warships.

Now other fleets are eliminating East China Sea type warships, so these unimportant sea areas have become temporary stations for East China Sea type warships, and during this period when new ships have not been built, such as Sakhalin Island in Beihai Province and Luzon are all East China Sea type warships eliminated by other fleets.

Zhang San watched their maintenance of the boats, as well as shooting drills, and generally speaking, the training was not bad, in fact, this was just a look, and in the afternoon he went to the army camp.

In order not to bring trouble to the local government, Zhang San returned to his boat to stay at night, and the boat did not stop when Zhang San rested, but went south out of Luzon Bay.

Tomorrow Zhang San will go to see some farms and the copper mines in central Luzon. In addition to encouraging private farms, Zhang San also set up a number of government-run farms in Luzon and the Ryukyus, which mainly used Japanese slaves, and compared with private farms, the grain obtained from these farms belonged to Zhang San, so when there was a shortage of grain, Zhang San wanted to come and see the production situation here.

The next day I woke up, the ship was still moving, and it was not until noon that Zhang San came to the farm, which was the southernmost section of the island of Luzon, and when Zhang San arrived, in addition to the person in charge of the farm who greeted him, there were also a large number of black slaves kneeling on the ground.
