Just after the fifteenth day of the first lunar month, Wang Dazhui finally came to Guangzhou City with a group of craftsmen.

As soon as Wang Dazhui arrived in Guangzhou City, Wang Mu, Minister of Industry, took Wang Mu to see Fang Nan.

"Teacher."

"The Grand Governor."

"Director Wang has worked hard all the way." Fang Nan said with concern to Wang Dazhui, the director of the factory is Wang Dazhui's identity, and his full name is the director of the Hutouzhai Arsenal, or the director of the First Arsenal of the People's Army, with the rank of deputy county level.

"It's not hard, it's not hard." Wang Dazhui hurriedly replied.

Fang Nan's words made Wang Dazhui sincerely frightened, Fang Nan is no longer an ordinary mountain man in the mountains, the People's Army has occupied most of Guangdong, Fang Nan's identity is infinitely higher in Wang Dazhui's heart, as if ordinary people have seen the emperor.

There are many, many people who have changed like Wang Dazhui, this is a change in identity and status, and Fang Nan is powerless to change it back, but fortunately, Fang Nan and the students are basically the same as before.

"Director Wang, your task will be very heavy next, Foshan Town is the place with the most blacksmiths in Guangdong and even in the world, I want you to build a new arsenal in Foshan Town to build more tiger head guns for the People's Army."

"Guaranteed to get the job done." Wang Dazhui said very seriously.

Fang Nan nodded and continued: "Building a new arsenal is only one of them, there is a second important task, you come and see. ”

Fang Nan led Wang Da Hammer and Wang Mu to a table, and then Fang Nan found a few drawings and spread them out on the table.

At the first glance of the drawings, Wang Mu recognized some of the contents on the drawings, for example, the largest part of the drawings was a waterwheel.

"As you all know, the most troublesome thing about building a tiger head gun is the two processes of polishing the barrel and rifling, which are very labor-intensive, so I want you to build this machine to speed up the efficiency of polishing the barrel and rifling.

It's a waterwheel, and the water wheel is driven to turn by the flow of water, and then through here, let it turn, and then go down step by step...... Finally let our machine turn on its own. ”

Fang Nan's drawings depict a hydraulic device, turning a manpower machine into a hydraulic machine.

Compared with manpower machine tools, hydraulic machine tools undoubtedly greatly save manpower, under the same number of people, increase hydraulic machine tools, the arsenal will be able to build more tiger head guns.

Manpower machine tools, hydraulic machine tools and steam-powered machine tools must be the most efficient and trouble-free steam-powered machine tools, but with the current situation of the People's Army, if you want to study the steam engine, you need more things, maybe the third encirclement and suppression of the People's Army in the Ming Dynasty began, and the first steam engine was built.

Even if the steam engine is built, it does not mean that the steam engine can be put into use, and it is not possible to build a steam engine that meets the requirements in a short time.

It takes a lot of time to study the steam engine, this hydraulic machine tool has become the best choice for the People's Army at present, there is no suitable place to use hydraulic machine tools in Hutou Zhai and Yongan County, Foshan is located in the hinterland of the Pearl River water system, the shipping is developed, the water resources are abundant, and there are conditions for the use of hydraulic machine tools.

In fact, the advantages of Foshan's abundant water resources are also one of the important reasons for the development of Foshan's smelting industry.

Foshan does not produce iron, Foshan is located in the alluvial plain of the Pearl River Delta, and there are no decent iron ore resources nearby.

According to the records of Foshan Ming and Qing Dynasty Metallurgical Casting, the iron ore in Foshan mainly comes from Luoding, Dong'an, Nanxiong, Shaozhou, Lianzhou, Huaiji and Yangjiang.

Volume 35 of the "Liangguang Salt Law Chronicle" also recorded: "The iron that covers the world is good in Guangdong, and the essence of the Guangzhou iron is none other than Luoding, whose iron is smooth and soft, and can be dialed as a line." However, its casting is also good, and it is not good at Foshan, so Guangzhou, Nanxiong, Huizhou, Luoding, Lianzhou, Huaiji iron, are lost in Foshan cloud. ”

It can be said that there are many iron ores in other areas of Guangdong, and the iron smelted from the iron ore produced is of high quality.

Foshan does not make iron personally, iron ore is smelted in the production area, the north and west of Guangdong are full of limestone mountains, limestone reserves are huge, smelting iron ore is very convenient and convenient, and the crude iron produced is transported to Foshan through the Xijiang River and Beijiang River and then further processed.

Iron smelting is inseparable from fuel, the Pearl River Delta region does not produce coal, and the main fuel for iron making in Foshan is charcoal.

Charcoal is a solid fuel formed by incomplete combustion of wood, or pyrolysis under the condition of isolated air, Foshan is located in the subtropics, dense forests, and the raw materials for the production of charcoal are inexhaustible.

Although the calorific value of charcoal is slightly lower than that of coke, a fuel commonly used in the iron and steel industry, it is enough to melt steel, and charcoal is also used in Hutouzhai ironmaking.

Building a hydraulic machine tool is the task of Fang Nan to the Ministry of Industry, Wang Da Hammer belongs to the Ministry of Industry, and the researchers of the Ministry of Industry continue to study the hydraulic machine tool, and then Wang Da Hammer personally builds it.

Hydraulic machinery this kind of thing has been in ancient times, there are many hydraulic machinery in the Ming Dynasty, it is not difficult to build, as long as a qualified hydraulic machine tool is created, it can be quickly popularized and used, and the time should be much earlier than the Ming army launched the third encirclement and suppression of the people's army.

Building a hydraulic machine tool is Wang Dazhu's second task, and Fang Nan gave the Ministry of Industry a third task: to quickly restore the production order of various subway mines in Guangdong and expand the output of crude iron and steel.

Steel is needed to build tiger head guns, tiger head guns, Franc cannons, grenades and other cold weapons, and it is enough to expand the production of crude iron and steel, but in Fang Nan's opinion, it is far from enough, because Fang Nan has a big plan in his mind.

Steel is the foundation of industrial development, and without enough steel, it is difficult for industry to develop, provided that there is a place where steel is useful.

As early as the Qin Dynasty, there was a kind of wooden rail road similar to the modern railway, using a special carriage to travel on the wooden rail road, the friction was greatly reduced, the horse could pull a lot of goods at a time, and the driving speed was not comparable to ordinary roads.

The wooden rails of the wooden rail road need to be made of hard wood, and they also need to be treated with anti-corrosion, which is more troublesome than building a railway directly from steel.

The People's Army does not yet have trains, but it can build railways ahead of schedule, and with railways, the speed of transportation of personnel and materials through railways can be greatly improved.

The construction of the railway will definitely cost a lot of manpower, but there are not many problems for the People's Army, in the first encirclement and suppression of the People's Army by the Ming Dynasty, the People's Army captured a large number of Ming troops, part of the Ming Army was transformed by the People's Army into the People's Army, part of the Ming Army was allowed to return home as a peasant, but some were used as coolies.

In addition to the coolies who were captured by the Ming army, there were also coolies who would be degraded to the evil after the raids of large households, and there were also a large number of hooligans and ruffians who became coolies, so it can be said that the People's Army had a large number of coolies in their hands, and even these coolies had become a trouble for the People's Army, and there were not so many coolies available in the Hutouzhai mine.

Now it is good that a lot of coolies are needed to expand the production of crude iron and steel in various places, and a lot of coolies can also be used to build railways, which is a good solution to the problem of too much coolies.
