In the Workshop Town Council Hall in the mountains near Kiyoshiyama Castle, Matsuura-gun, Kyushu Hiraki, was carefully checking the account book.

In addition to the previously introduced gold, silver, copper, tin, lead and coal mines, this time the account book also added sulfur, porcelain clay ore, and limestone ore.

In terms of sulfur ore, high-quality sulfur ore was found on Tianshan Mountain in Songpu County, Feiqianguo and Asu Mountain in Asu County, Feihouguo. Among them, there is only one sulfur ore in Feiqianguo, but three sulfur ore have been found in Asu Mountain in Feihou.

Sulfur is a good thing for the territory. First of all, it is an important raw material for gunpowder production in the Luo Family Weapon Workshop. Secondly, it can also be used in the marching camp. As long as you sprinkle some sulfur around the camp (be careful to dosage so as not to be used by the enemy for burning the camp), you can avoid being harassed by snakes, insects, rats and ants at night.

Finally, it can be mixed with other fertilizers for crop fertilizer. The excess sulfur can also be sold to Ming Dynasty merchants and southern barbarians to increase territory income.

Now the four sulfur mines discovered have entered the mining stage. With the internal affairs cabinet further exploring the territory, it is estimated that new sulfur deposits will be discovered in the Asushan area.

In terms of porcelain clay ore, with the help of several Ming Dynasty ceramic craftsmen, the Luo family has discovered a large number of porcelain clay ore in Imanli Bay in Matsuura County, Himakikuoku and near Arita Village. In addition, porcelain clay ore has also been found near Xiaoluta Village at the foot of Fenghoukuokuokuokuokuoku.

Ceramic vessels are quite popular in Japan, especially those that use the Ming Dynasty ceramic production technology. Although there are only a few ceramic craftsmen from the Ming Dynasty at present, Zhengliang still decided to establish workshops one by one near the three porcelain clay mines discovered above after the autumn harvest this year to produce its own ceramic vessels belonging to the Luo family. These ceramic vessels are used for external sales on the one hand and for the needs of their own territory.

In terms of limestone, a large limestone deposit was found in the Xukongzang Mountains of Feiqian Country, the Anyue Mountains of Anyue Mountains, and the Gaofeng Mountains of the Houguo, and the Asu Mountains of Feiqian Country.

In fact, although Japan lacks minerals such as abundant iron ore, it contains a large amount of raw materials for making cement, especially lime ore, which can be found almost in the mountainous areas of the Luo Family Territory. However, this mineral deposit that was eventually selected as a mining site is the best quality among many limestone ores with the largest reserves.

More importantly, the raw materials for producing cement can be easily obtained in the areas around these minerals. Therefore, the Luo family has already established cement production workshops in the local area. Just like paper workshops, villages mainly composed of craftsmen, workers and their families in the workshops have been formed near these workshops. While providing cement raw materials for various marching avenues and buildings in the territory, they also provide impetus for local economic development.

Of course, due to the lack of advanced equipment (it was impossible to exist in this era), the cement produced by these workshops is inferior, but it can fully meet the needs of the use of the marching avenue. Moreover, when combined with local mud, it can also be used as a material for building buildings. Their formation effect is better than using mud alone.

In general, the Luoshijia currently has a gold mine, four silver mines, four copper mines, one lead mine, one tin mine, four sulfur mines, one coal mine, three porcelain clay mines, four limestone mines, and also a paper workshop, a textile workshop, four cement workshops, and three ceramic workshops that are about to start construction.

After learning about all the current mineral deposits of the Luo family, Masayoshi inspected various workshops in the Workshop Town accompanied by his retainers.

In the weapons workshop, Masayoshi carefully watched the production process of long spears, bows, feather arrows, samurai swords, black hawk daggers (stimulating weapons, black hawks and reconnaissance equipment), flying fire meteor projection vehicles, cloud ladders, city-breaking vehicles, new-type complete (combined with leather armor and iron sheets), new-type armor and other weapons and armor.

Regarding the Flying Fire Meteor Projector among them, Masayoshi Hope Country's friendly soldier, Liu Ye, finds ways to improve it, so that these projectors that can only project turret stone tanks can be transformed into catapults that can project boulders. At present, due to the material limited to the actuation of starting the elastic, the material cannot withstand the problem of excessive tension caused by launching boulders, so these projectors cannot fire boulders.

Regarding this issue, Zhengliang first thought of rubber. Just to have rubber, there must be rubber trees. However, rubber trees are native to South America and were transplanted to Kew Gardens in England in 1873. In 1877, 22 three-leaf rubber trees were transported to Singapore, spread to the Malay Peninsula in 1898, and China began to introduce them in 1904. At this time, no matter in the local or in the Ming Dynasty, it is impossible to find rubber trees (as for sending people to find them back or entrusting the Southern Barbarians to help you find them specifically, you can only ask the Southern Barbarians and Ming merchants to pay attention). So rubber doesn't need to be considered.

Then the other way left is to go out to sea to hunt whales. The rubber bands on whales can be completely suitable as materials. It is not easy to hunt whales. Although there will definitely be no fewer whales on the sea at this time, the ocean is still quite large, and it is not easy to find them immediately. Moreover, with the current strength of such ships, recklessly going to hunt whales may cause their own losses. Therefore, the whales can only depend on opportunities.

After thinking about it, there was no very good way to solve the problem that the projector could not launch a boulder. Zhengliang had to give some suggestions and let everyone in the workshop think about it slowly.

Then Zhengliang inspected the firearm workshop and carefully watched the production process of gunpowder, bullets, shells, iron cannons, and large tubes. For the production of large tubes, Zhengliang's only requirement is to find a way to increase the output. At present, the Luo family only has one large tube (it was installed on the fort in Qibucheng as a defensive weapon), and two large tubes will be produced next month. However, even if all the large tubes produced this year can be successfully put into use after testing, there will be only five large tubes at most, which obviously cannot meet the needs of the Luo family's military force. Therefore, it is urgent to improve the production efficiency of large tubes.

As for gunpowder and iron cannons, Zhengliang put forward suggestions for improvement. At present, the gunpowder produced by the Luo family itself contains a lot of impurities and inconsistent material ratios during the configuration process, resulting in low power of the gunpowder and inconsistent power of the gunpowder produced in different periods. This brings great inconvenience to the iron cannons when using iron cannons, and may even cause accidents, resulting in unnecessary casualties in the iron cannons.

For this reason, Zhengliang asked the firearm workshop to create special proportional utensils so that each time the gunpowder is made, this utensil is used as a utensil, so that the power of the gunpowder can be reduced or too high due to inconsistent placement of various materials.

Regarding the impurities in gunpowder, Zhengliang asked the smelting workshop to also participate in the research on this issue and find ways to solve the problem of the reduction in the power of gunpowder due to the various raw materials containing impurities.

As for iron cannons, the Luo Family's iron cannons are currently much more advanced than those in other regions in terms of overall structure and use of wet weather. Masara once sent Kizaki Shigetachi to spend a lot of money to buy one iron cannon from Kyoto, Ome, Saga and Satsuma respectively, and then used the same ammunition to test the same to compare the differences between these iron cannons and the Luo Family's iron cannons.

Finally, it was discovered that the Luo Family's iron cannons were better from the structure, convenience of carrying and convenience of using the gun body than the iron cannons in other regions. After the test firing, it was found that the Luo Family's iron cannons can not only shoot in wet weather, but also have a shooting distance of farther than the iron cannons in other regions, at least more than ten meters away.
