These indigenous soldiers, can be said to be natural warriors, not only very hard-working, as long as the training is good, the sense of obedience is also very strong, at the same time, they live in the jungle all the year round indigenous warriors, extremely good at jungle warfare, although they do not like to use muskets and other hot weapons, but they are extremely good at using a variety of cold weapons to fight, bows and arrows blow arrows, which are not valued by the sea wolf, cold weapons, in their hands can play a very strong combat effectiveness, so that many sea wolf officers are surprised.

In the previous Xiaotian anti-bandit operations on the land in Fujian, it can be said that there are these indigenous soldiers, they are good at hiding, tracking, setting traps, sneak attacks, reconnaissance and other operations, often out of nowhere, unexpectedly attack the enemy, in the mountains and forests of Fujian to suppress bandits, it can be said that there is no disadvantage, so that many veterans of the sea wolves, are amazed by their ability.

Of course, the sea wolf depends on the natural industry, Yu Xiaotian since the seventh year of the apocalypse, a large number of earthen blast furnaces in freshwater have been built.

During the initial operation of these soil blast furnaces, the production was very unstable, and the product quality could not be guaranteed.

But even in this case, Yu Xiaotian still insisted on the production of the earth blast furnace, found a group of capable craftsmen, and made detailed records of the feeding ratio of each furnace, as well as the furnace temperature and other data, and then according to the situation of the product, constantly summarized and analyzed, and accumulated experience.

After more than two years of continuous testing, these craftsmen have basically mastered some preliminary production techniques, which can produce some relatively good steel, the waste rate of raw materials has also been reduced a lot, and the accident rate has also been greatly reduced.

By the time of Chongzhen's fourth year, the number of earthen blast furnaces in Tamsui had reached more than 30, which could produce dozens of tons of steel per day, and these steels were not only used in the production of muskets, but also used in many industries, although they still could not meet the needs of the sea wolves, but after all, they had taken a valuable step.

In addition, Yu Xiaotian has not dared to be lazy in the past few years, in addition to being busy with the construction of the army in Fujian, as long as he has a little leisure, he will quickly get into a big room specially set up behind his mansion, while often racking his brains to draw some mechanical drawings, while commanding dozens of skilled carpenters and blacksmiths to make various mechanical models, or to explore some mechanical processing technology.

Yu Xiaotian only hated that when he was in college, he didn't learn more mechanical knowledge, and now when he uses it, he hates that his accumulation is too little, so that many problems that seem easy to solve in later generations have become insurmountable problems in his hands, and he can only keep racking his brains to explore.

In May of the third year of Chongzhen, the first hydraulic machinery factory in Tamsui finally produced the first "qualified" wheel bearing, and installed it on a carriage for testing, this carriage is powered by oxen, carrying nearly a ton of goods, running for hundreds of miles, the bearing is damaged, although it can only be regarded as a defective product in later generations, but in this era, it is already an absolute black technology.

The successful development of bearings, for the industrialization process of the sea wolf, and laid a solid foundation, as various types of bearings began to be produced in small batches, some machinery began to replace the bearings in the first batch, greatly reducing the power loss, but also greatly improved the production accuracy of some soil machine tools.

Soon after, Yu Xiaotian experimentally used the soil gear hobbing machine to manufacture industrial gears according to the principle of involute, and a few months later, this kind of gear also began to be applied to the machinery factory, and the first batch of modern and primitive industrial machine tools began to be officially put into use.

Of course, the failure rate of these machines is so high that it can be said to be outrageous, and it is not too much to say that their quality is miserable, but this is the first step after all, as long as it is taken, it will be solved gradually sooner or later.

And the progress of industry, but also let all walks of life have really enjoyed the superiority, not to mention the military benefits, even the lowest level of sugar liao, the Ming Dynasty sugar liao, the use of rollers are all wooden, plus the transmission mechanism is also wooden, when used, the juice yield of rolled sugarcane can not even reach 40 percent or even lower, even the stone is not as good, but it has been used for hundreds of years, there is no improvement.

The waste caused by this is huge, it is unimaginable, a large amount of sugarcane can not be rolled out of sugarcane juice, so it is treated as waste, so when the seawolf is preparing to build the sugar house, it directly abandons this wooden rolling mill, and uses cast iron to make iron rolls, coupled with the application of bearings and gears, so that the juice yield of the sea wolf's sugar mill can be increased to seventy, and when repeatedly squeezed, it can even reach more than eighty percent.

In this way, the same sugarcane, in the sugar liao of the sea wolf, can be squeezed out of the sugarcane juice, than the sugar liao squeezed out of the sugar liao in Guangdong, Guangxi on land, nearly twice as much, the sugar yield is naturally twice as high, plus after repeated summing up experience, the quality of the sucrose produced by the sea wolf's sugar liao has improved rapidly, the color of the delicate white sugar is white, refreshing and clean, and the selling price is naturally high.

In this way, the benefits of one acre of sea wolf's sugar cane field are at least more than twice that of the sugar cane field in Guangxi on land, and the cost of manpower and material resources is much lower than that there, so it naturally makes a lot of profits.

The sea wolf also attaches great importance to the application of various scraps, after the sugarcane juice is extracted, the remaining bagasse can be used to make wine, and the sugarcane wine brewed has a sweet and sour taste in the taste, which is actually very popular with the Dutch and Portuguese, and a large number of exports are exchanged for silver.

This is just a typical example, and things like this are reflected in various fields, such as carpentry, farm tools, vehicles, etc., all of which have benefited a lot.

If you want to say that the biggest benefit, I am afraid that it is still the military aspect, the application of bearings and gears, so that the handling performance of the ship has been improved again, and the operation performance of heavy artillery has also been improved, becoming much lighter.

Especially in the army, after the bearing is used on the gun carriage of some artillery, it is much lighter to tow, and after the addition of a screw that can adjust the height and elevation angles, the operation is also much simpler and more accurate.

Of course, this is not the most important, the most important thing is that with the production of steel and the application of various primitive machine tools, Seawolf's wolf tooth rifle finally began to use steel instead of the original wrought iron, so that the service life of the barrel has been greatly improved, the previous maximum of 100 bullets, can grind the rifling bald, so that the wolf tooth rifle, has never been able to fully replace the South Japanese flintlock pistol.

However, after switching to steel as the raw material for the production of the barrel, coupled with the continuous improvement of the original machine tool, the service life of the barrel of the wolf's tooth rifle has increased from dozens of rounds to hundreds of rounds, and the life of the barrel rifling has increased more than ten times.

A new wolf's tooth rifle can at least be used for a period of time, which has reduced the pressure on logistics a lot, and there is no need for the logistics department to reserve a large number of barrels and replace them at any time.

Without a large reserve of reserve barrels, the production of wolf-tooth rifles has also been greatly increased, and the army of the Seawolf Group can finally be replaced with wolf-tooth rifles in large quantities, and the combat effectiveness can be improved by more than a few percent, and the army equipped with wolf-tooth rifles on the battlefield can almost crush the enemy ten times their size.

In the past, because the life of the barrel of the wolf's tooth rifle was too short, so that the officers did not dare to let the soldiers shoot live ammunition frequently, they could only use long-term gun aiming training, and use ordinary Nanji-style rifles to conduct live-fire training, such training results must not be very good, a large number of soldiers who use wolf-tooth rifles can not give full play to the advantages of long-distance accurate shooting of rifled guns on the battlefield, and can only ensure a relatively accurate shooting hit rate of about 100 meters.

However, after improving the barrel material, the barrel life has been greatly improved, and the officers are no longer as stingy as before, so that soldiers can use the wolf's tooth rifle more for live-fire training, and better master the performance of the wolf's tooth rifle for long-distance precision shooting. It has the ability to effectively snipe enemies from a distance of 200 meters.

Even those sharpshooters have also made a lot of profits, in the past, because they did not dare to shoot a large number of live ammunition, the ability to snipe targets from a long distance could not be fully utilized, but now they can carry out a lot of live ammunition training, so that their shooting accuracy has also been effectively improved, coupled with the improvement of processing accuracy, so that the accuracy of the wolf's tooth rifle has improved a lot compared with before, so that some sharpshooters can actually hit the enemy at a distance of 400 meters.

Think about it, the enemy's artillery may not be able to hit 400 meters, but the enemy's gunners are within the effective sniper distance of their own marksmen, and the sharpshooters can easily suppress the enemy's artillery on the battlefield.
