Because of the People's Army's talent absorption examination, there are still several cases in Guangzhou City, such as Lu Yu and his friends cutting off their robes and breaking their righteousness, and more people have no intention of defecting to the People's Army, and some people want to join the People's Army but are worried that the People's Army will be exterminated by the Ming Army.

However, the "Common Sense" (traditional Chinese version) sold in the Wenhua Bookstore can be called a big seller, almost literate people are one person, even Qiao Rong, the father of the Qiao sisters, also took a copy to watch, the content of the common sense book is really curious, even if it is impossible to judge the truth or falsehood, but it is still okay to see it as an interesting thing.

In addition, the content of the common sense book is indispensable, which has attracted heated discussions among many literati and scholars.

……

Foshan Town, Foshan Arsenal, and new hydraulic machine tools have been added to the production of tiger head guns, which makes many craftsmen look forward to it.

The core and most difficult part of making tiger head guns is the barrel, first the craftsman hammers a piece of iron sheet into a rough barrel by hand, and then the craftsman uses a manpower machine tool to drill and grind the rough inner wall of the barrel little by little, and the barrel after drilling and grinding can be used as a smoothbore gun.

But the tiger head gun is a rifled gun, and it is also necessary to rifle the barrel, and the difficulty of this step is not weaker than the previous step.

The first step of building the barrel cannot be changed for the time being, but the second and third steps can be changed, and with the efforts of Tang Bei and Wang Dazhui's research group, a hydraulic machine tool with the same function has been studied and manufactured to replace the manpower machine tool.

A water force and a manpower, people will be tired, but water can flow all the time, and the "power" of water is much greater than people, in the two steps of drilling and grinding the barrel and rifling, the efficiency will be greatly improved.

With the addition of more hydraulic machines, a part of the craftsmen can move on to the first step of making the barrel, and the production of the barrel increases, and the production of the tiger head gun increases.

Created a hydraulic machine tool with his own hands, Wang Dazhui was also very emotional, but he didn't expect that the hydraulic machine tool was so much easier to use than the manpower machine tool.

As a member of the People's Army, Wang Dazhui can be said to have witnessed the birth, growth and rise of the People's Army.

Wang Dazhui knew very well that as long as the People's Army was equipped with enough tiger head guns, the People's Army would be able to overthrow the Ming court, and the key was that tiger head guns were too difficult to build and the output was relatively small.

Since the People's Army occupied the territory, it has been looking for craftsmen to send to Hutou Village to increase the production of tiger head guns, and the arsenal has also developed from one to three, and even the Hutou Zhai Arsenal and Yongan County Arsenal together are far from being comparable with today's Foshan Arsenal.

It won't be long before the Hutouzhai Arsenal, located in the mountains, will be shut down.

Although the Foshan Arsenal is large and can produce more tiger head guns, but now in the battle between the People's Army and the Ming Army, it seems that the effect of grenades is greater, but there are still too few tiger head guns.

Wang Dazhui felt that if the People's Army could have a force of 10,000 people, all armed with tiger head guns, it could easily defeat an enemy ten times its size on the battlefield.

Nowadays, with the addition of hydraulic machine tools, the production of tiger head guns will continue to increase, and more tiger head guns will be equipped with the people's army, and the strength of the people's army will increase, and it will also have the confidence to face the Ming army that continues to gather.

Looking at the hydraulic machine tools, Wang Dazhui's confidence in the People's Army's overthrow of the Ming court was greatly increased.

However, there are also defects in hydraulic machine tools, hydraulic machine tools must be built near the river, which is the site limitation, such as the Hutouzhai Arsenal located in the mountains, and the arsenal in Yongan County, can not use hydraulic machine tools.

Wang Da Hammer is very much looking forward to the steam power machine tool described in Tang Bei's mouth, the steam machine tool is much smaller than the hydraulic machine tool, there is no site limit, that is the best machine tool, Wang Da Hammer has decided to join the research of the steam engine, but now it is necessary to build and improve the hydraulic machine tool, the research on the steam engine has to wait, and the steam machine tool will take a few years to be able to study.

Therefore, Wang Dazhui now focuses on hydraulic machine tools, and leads people to build more hydraulic machine tools for Foshan Arsenal to use in the manufacture of tiger head guns.

At present, one of the centers of gravity of the People's Military Government is the Foshan Arsenal, followed by the Hutouzhai Arsenal, the Yongan County Arsenal, iron ore mines and shipyards throughout Guangdong.

Hutouzhai Arsenal and Yongan County Arsenal were skipped, because of the addition of a large number of coolies, the ore output of each subway has been effectively increased, and even exceeded the iron-making capacity of various places.

The iron-making workshop was built near the iron mine to facilitate iron-making, and the crude iron from the iron-making workshop was transported to Foshan, and then further smelted by the iron-making workshop in Foshan.

Wang Mu, the minister of industry, plans to build several large steel mills on sites across Guangdong to smelt iron ore and increase steel production, but this plan will last for several years, and there is a more important precondition for railroad tracks.

With the railroad road, even if there is no train, the horse-drawn carriage can run on the railroad road, and the efficiency of transporting goods is greatly improved, which is convenient for sending iron ore from all over the country to the steel plant.

The shipyard after the steel mill can maintain the status quo, and the People's Army has no plans to expand overseas for the time being, and is not even very interested in overseas trade.

However, if we do not expand overseas now, we will continue to do so in the future, and shipyards must be retained and continue to train craftsmen and even shipbuilders.

Road repair, construction of hydraulic facilities and so on are the affairs of the Ministry of Industry, but recently Fang Nan handed over two research tasks to the Ministry of Industry, asking the Ministry of Industry to allocate manpower to complete these two tasks as soon as possible.

Two research tasks, one for cement and one for glass.

The role of cement is mainly to build roads, build water conservancy facilities, build houses and other civil engineering, with the addition of cement, the efficiency of these civil engineering projects can be improved, and the quality can be improved.

For example, road construction, in this era, the main road construction is to fill in the ground, drag the roller to roll the road surface, and at most pave a layer of small stones, which is a good official road, and it is not yet extravagant enough to pave the road with bricks.

This kind of official road is still relatively difficult to pass in rainy conditions, and if it is a cement road, it will not be muddy at all on rainy days.

There are four main functions of glass, one is used as a mirror, one is when the door and window glass improves the light in the house, one is ground into a telescope, and the other is ground into a microscope.

The importance of cement and glass is very high, if Fang Nan was born in a large family, with cement and glass, it is easy to become the richest man under the Ming Dynasty, and he can also use cement or glass technology to get on the road with the powerful.

The primary cement technology and glass technology are not very difficult, and even Fang Nan will participate in the research and point out the direction for the project team.

For Fang Nan, the first purpose of studying cement and glass is not to make money, the emergence of cement and glass will have a great impact on the military, people's livelihood, industry and other aspects of the People's Army, which is the most important.
