In later generations, more than a hundred iron ore resources in ZJ were investigated, and twenty-two of them had proven reserves, with a total of 98 million tons.

The locations of these iron ore are relatively concentrated areas such as the area of ​​the northern part of Zhuji County, Shaoxing Prefecture to the Nizhu area in Shaoxing, Yanzhou Prefecture, Anyang area to Tongshan area, Huzhou Prefecture, CX County, Heping area to Tuwangdong area, Xianlinbu County, Yuhang County, Hangzhou Prefecture, and Baoshan Chimu Mountain in Jingn County, Chuzhou Prefecture.

Huzhou and Shaoxing are still under the control of the Qing Dynasty. In contrast, Shaoxing is actually very close to Chen Wen, especially Zhuji in the south, Xinchang and Sheng County are completely exposed to the Ming army's military. Just as the sea trade and a large amount of military pay is collected, Chen Wen plans to carry out a new round of military expansion first, in order to prepare for a chain reaction after a large-scale northward move.

This time, Zhang Bang's exploration of iron ore was the Tongshan Iron Mine in Yanzhou Prefecture, the Jin Iron Mine in Sm County, Taizhou Prefecture, and the Baoshan and Baixi Iron Mine in Chuzhou Prefecture. Among them, Tongshan Iron Mine was discovered and mined in the Tang Dynasty. However, at that time, it was mainly copper smelting, not iron smelting, and the name of Tongshan also came from this.

These places are actually not rich mines, especially Baixi Iron Mine. However, Chen Wen did not intend to use them as the pillar of development. It was just a transition. After surviving this period, Ma'anshan is enough, so what else should I consider?

Of course, in normal heavy industry, coal and iron are inseparable, but in the era in which Chen Wen lived and the industrial level of the Ming army occupied the area, coal mines are not indispensable. It can even be said that they should try to eliminate military production.

Chen Wen remembered that he had seen such a statement on the forum before, saying that the reason for the sharp decline in the quality of weapons in the Ming Dynasty was that coal was widely used to smelve iron. Various elements contained in coal that were not conducive to the quality of weapons penetrated into the iron, resulting in the quality of the iron weapons produced far lower than that of the rb Japanese swords of the same era.

This statement makes sense in principle. Chen Wen also searched online and found that the UK in the same era was forced to cast iron cannons in large quantities due to its low copper production, but its price was much more expensive than that of iron cannons in other European countries. The reason for this problem is that the British strictly prohibited the use of coal in the production of iron cannons, but used a large amount of charcoal, which even led to the extremely low forest coverage rate in the UK due to the transition from cutting to death for a long time.

In exchange for this price, the quality of British artillery and the artillery that was dominant in Europe at that time, the red artillery imitated by the Ming court was actually the British naval gun salvaged by the Dutch. Another artillery power, France, was about to be found after the Napoleon era, and even after the birth of "Miss Seventh Five", which was already very far away from today.

The strict use of charcoal to smelify iron was continued in Britain until the 18th century when coking coal began to smelify iron, but it was only slightly alleviated. In the true sense, the complete replacement of charcoal with coal can still ensure the performance of the iron cannon, but it was achieved only after the desulfurization and dephosphoration method appeared in the second half of the 19th century.

Because of his understanding of this, the jurisdiction of military manufacturing has been transferred from civil servants to his hands. The Ming army's weapons have been completely replaced by charcoal. While the cost increases, the quality of weapons has also been greatly improved. Only when the weapons are damaged in battle, cannons exploded, and other phenomena are greatly lower than those of the Qing army, which is still using coal to make iron.

During the Ming Dynasty, the steel smelting level was once ahead of the world, but the Qing Dynasty had almost no progress for more than 200 years before it was overtaken by the rapidly developing European powers. Among them, the steel-frying method and iron-frying furnace recorded in "The Heavenly Gong Kaiwu" have now begun to be used in the Ming army's military industry workshop. Chen Wen even thought about sending people to JX to invite the encyclopedia-style scientist Song Yingxing in the late Ming Dynasty. It was just that the mountains were high and the road was far away, and the Qing army's blockade failed to make a journey.

Chen Wen sent someone to do the iron ore matter, but this time he came here specifically. In addition to the Zheng family's order, Chen Wen also planned to see what progress the weapon he ordered to develop last time had reached.

"That, Duke, the minister urged me a few days ago. The basic principle has been understood. In order to achieve the effect you mentioned, there is still a problem that needs to be solved..."

After hearing Xu Yi's problem, Chen Wen was not very clear about how this was solved, so he had to let the R&D personnel of the Military Industry Department continue to experiment and not do what he thought.

"Well, Lumi guns, we still have to continue production. At the same time, I need your Military Industry Department to start putting the research and development task of the turtledove-legged gun on the agenda."

The turtledoubled gun is the largest musket with the inner diameter in the Ming Dynasty. Its mass of projectiles can be as high as 68 grams, which is already an absolute heavy convex gun. The body of the turtledoubled gun is so heavy that it requires a bracket to be effectively launched. Its range and effective killing are not comparable to the Lumi gun that Chen Wen is now equipped with, let alone a bird gun.

This time, the reason why he could think of this was actually due to Zheng Chenggong's blessing. After the Songjin War, the Ming court deliberately transferred Zheng Zhilong's navy to go north to help defend Juehua Island. Zheng Zhilong was afraid of the Qing army like a tiger and was reluctant to let FJ's sea trade profits. He used the excuse of only GD to make a sharp weapon like a turtle dove-legged gun. In the end, he spent money to connect the relationship and only transported a batch of weapons to Dengzhou.

The turtledove-legged gun is recorded in "Wu Bei Zhi", but Mao Yuanyi's book was a bit complicated and unspecified. If it weren't for Zheng Zhilong's son who wanted to buy the Lumi gun, Chen Wen would probably not remember the turtledove-legged gun that he had read in the novel before.

"This should not be too difficult. After the research and development is successful, I will study the proportion and quantity of mass production. However, that thing must be done quickly."

Xu Yi liked the work of the Military Industry Department very much, especially when he saw the weapons and armors were built to equip the army. The joy was difficult for other departments to understand. However, this research and development task was not like normal production, and it was okay to have books to record, but there were similar things like the things mentioned by Chen Wen, but there were many technical problems. In addition, he was never a scholar who was interested in these things before, so when he heard Chen Wen’s re-reported old things, Xu Yi really had a bitter face.

Nowadays, the Ming army includes Nantang, Jinwei, Shentang, Yiwu, Dongyang, Pujiang, Lishui, Chun'an and Yushan, as well as the cavalry battalion named Iron Cavalry and the yet-unnamed mule army. There are nearly 20,000 combat soldiers alone, and this is not included in the local garrisons stationed in various prefectures and counties.

With such a scale, when the troops are surrounded by heavy troops, they are actually just a temporary guarantee that they will be attacked by the Qing army and that there will be no excessive losses in the local area.

Even though Chen Wen knew little about modern naval or the navy in the Middle Ages, he could understand this principle.

However, it is not possible to get his recognition to a group of naval officers and soldiers who have not been taken for a long time to face the armed merchant ships, or even warships. In addition, whether attacking armed merchant ships will lead to the corruption of the military discipline of the naval officers and soldiers is also a big problem. It is not as good as on the road at sea. If a military judge or supervisor is used improperly, it is likely that the sailors will be backfired. We must study all the tricks here clearly before talking about them.

Because of this, Chen Wen also settled for the issue of naval troops going to sea for training and asked them to clear out the pirates on the coast of Taiwan and Wen.

On the 12th day of the 12th lunar month, the algorithm of the lunar calendar naturally cannot be linked to the Xi'an incident, let alone the Double 12 promotion. However, for the zj coastal cruise navy, this is the first time they went out to sea to clear out pirates.

Taizhou Bay is only a few dozen miles away, and a series of islands including Lighting Island, Yijiangshan Island, and Dachen Island are arranged along the coast of Taizhou.

The first attack, but the details of the target were already found here - there were only hundreds of people, several large and small ships and one or two small cannons. However, even so, adhering to the principle that the training of soldiers was to achieve success in fighting against the rabbit to enhance the confidence of the navy, the Taizhou squadron of the coastal cruise navy still dispatched more than a dozen large and small warships.

The gun ships purchased from FJ are generally almost the same as those of large merchant ships from the Netherlands and Portugal and bird ships from the same place. In Zheng Chenggong's army, a small number of them were modified from European merchant ships. The bows of this kind of warship can be equipped with a red cannon weighing three or four thousand kilograms, which are basically between eighteen and twenty-four pound cannons, and there are more than twenty ordinary cannons ranging from one to another on both sides and more than one hundred muskets.

In comparison, the rush boat is slightly smaller, with the two-layer artillery decks on both sides, and there are more than twenty gates. The double-sailed rush boat is smaller than the rush boat, but the structure is roughly the same as that.

A fleet of such a large scale may not necessarily have the confidence to win even if the Qing navy in Ningbo, let alone those little pirates.

The battle process can only be described as crushing. Moreover, this is the Ming fleet used a rushing ship and several smaller double-sailed ships to lure the enemy, and only sent a signal after receiving the fire. Originally, the Ming Navy was about to jump into the gang and fight the pirates after a round of artillery attacks, but when the main force appeared, the pirates immediately lost their fighting spirit. Because the distance was too close, only two pirate ships were able to escape. The others were either sunk directly, burned, or captured by the Ming army.

After the battle, the Ming army dispatched sailors to land on a small boat and took the village on the target island. The men, the elderly, the weak, women and children took away all the money, livestock, food, etc., and left a red pen to tell the wooden board to order them to go to the Haimen Guard to reunite with their families. Before leaving, the village was lit, and the army set off and returned, easily winning the first battle.

Throughout the twelfth lunar month, the zj coastal cruise navy was always clearing out pirates, and Chen Wen was busy in the yamen of the Duke of Xiuguo's Mansion just changed the plaque in Jinhua Prefecture.

The army is expanding, military fields are being distributed, and bulk trade with the Zheng family is in progress. Government offices including Maritime and Salt Courses are being established. In addition, autumn taxes are being collected, so there is too much to be busy.

On the 29th day of the twelfth lunar month, on the last day of the seventh year of the Yongli year, some craftsmen, officials and soldiers in the subordinate departments had already begun to take leave, but Chen Wen was summarizing the year-end with the various departments of the Xiuguo Duke's Office and the main yamen under the Governor's Office in the Grand Conference Hall.

"In the past seven years of Yongli, my king's army recovered the remaining prefectures and counties of Yanzhou, Taizhou and Wenzhou, Quzhou and Chuzhou, and expanded its power to Guangxin Prefecture in JX and XS County in Ningbo, and made great achievements today. You have made great contributions to the country. However, what I, Chen Wen, want to tell you today is that next year, the eighth year of Yongli, will be the year when my king's army rises up and recovers more lost lands, and it is also the year when the Tartars' rule in these four southeastern provinces will be completely collapsed."
