Zhu Youjian made a decree and promoted Tang Ruowang to Langzhong of the Fire Gun Bureau of the Ministry of Industry, and led the official position of Shao Zhan of the Zhan Mansion.

This is a four-grade official, in the past, it was a noble official position that belonged to the Qingliu officials of Hanlin, and the subordinate officials of the Prince's East Palace were basically a process that officials had to go through from Hanlin to the cabinet.

However, Zhu Youzhen asked Tang Ruowang to be the Shao Zhan Shi of the Zhan Mansion, not to let him join the cabinet, but to show that he attaches great importance to scientific research.

Tang Ruowang, who took off his blue clothes and changed into red robes, looked at the four thousand craftsmen dumbfounded.

He never imagined that he would have to manage so many people to make flintlock pistols with him.

"Your Majesty is obviously wrong, this is not something that can be made by a large number of people", John Tang complained in a low voice, and sat down at the wooden table and began to think about how to start the manufacture of flintlock pistols.

The 4,000 craftsmen were also dumbfounded, and the craftsmen assigned to the Iron and Steel Smelting Bureau all had official status, official uniforms and silver dollars. Why didn't this foreigner who cared about himself move for a long time, just sitting in place and looking at the picture, why was he stunned?

There were 3,000 men in the Artillery Bureau, and the idea was the officials and craftsmen who had previously been responsible for casting the guns and involved in the storage and transportation of the artillery.

Zhu Youzhen had already asked Sun Yuanhua's second son Hedou to be the Langzhong of the Artillery Bureau a few days ago, and at the same time led Shang Bao Sicheng.

In the fifth year of Chongzhen, because of Wen Tiren's frame-up, Sun Yuanhua was killed, and Zhu Youzhen also restored Sun Yuanhua's reputation a few days ago.

And Sun Yuanhua's third son was also summoned to Nanjing by Zhu Youzhen, and Sun Hedou inherited his father's artillery-casting skills, so it was naturally appropriate for Sun Hedou to lead the artillery bureau.

Sun Heding was the Langzhong of the Gunpowder Bureau of the Ministry of Industry, but there were not many craftsmen in the Gunpowder Bureau, but there were more than 1,000 people.

Zhu Youzhen asked Sun Yuanhua's eldest son, Sun Heding, to manage the Gunpowder Bureau, because he wanted to appease the unjustly killed ministers and sympathize with his children, and also took into account that Sun Heding had followed his father since he was a child.

At least, Sun Heding is better at gunpowder research and development than the sour Confucians who only read the Four Books and the Five Classics.

As for Wang Gongchang, which specializes in the production of unconventional weapons such as earth-shaking thunder, 10,000 enemies and other defensive and melee explosive weapons.

Zhu Youzhen also let Sun Hejing be the Ministry of Works, and Langzhong temporarily took charge of Wang Gong's factory.

Sun Heding, Sun Hedou, and Sun Hejing are naturally different from Tang Ruowang, and the three of them have now reported to their officials and craftsmen, and the three of them have also received Xu Guangqi's teaching in Shanghai from their fathers, and they are more familiar with the firearms manufacturing process, and they began to draw up plans according to Zhu Youzhen's instructions as soon as they came.

Zhu Youzhen's requirements for artillery are the same as those for firearms, and they do not need to be varied, but they must also have key points and a clear direction for improvement.

Western artillery uses the weight of shells as the standard to divide artillery, and Zhu Youzhen also requires that the artillery of the Ming Dynasty should also have artillery types that meet different firing ranges, and divide the artillery by the caliber of the barrel, which is more convenient for the shell to be paired with the barrel, and it is more convenient to compare the weight of the shell.

Artillery division is one thing, there is a drawback of the Ming artillery also has to be corrected, due to the influence of the previous craftsman system, R & D investment and enthusiasm is not enough, most of the Ming artillery comes from imitation, but the imitation of the Fran cannon and the Hongyi cannon are not the most suitable field artillery, the former is too small, the latter is too big and heavy, one is suitable for naval warfare and one is suitable for defending the city.

For field warfare, the tiger squat cannon used by the Qi family army as a curved artillery is quite suitable for field warfare in mountains and jungles, similar to mortars.

That is to say, Daming also needs to independently develop a series of flat-fire guns for land field warfare, which can meet the requirements of different ranges according to the caliber.

The most important improvements to the Daming artillery were not the above, but the application of ranging rulers and aiming gates.

The ranging ruler and aiming door are equivalent to the eyes of artillery, and the previous Daming artillery had no eyes, and it was all based on the experience of artillery, which was naturally inefficient, and even injured their own infantry camp.

The biggest difference between the Ming artillery and the Western artillery is not the forging of the barrel, which can be improved by the improvement of the Iron and Steel Smelting Bureau, but what really needs to be cast by the Artillery Bureau is the eyes of these artillery.

I don't know if Tang Ruowang deliberately hid his personal interests or the domestic geometry of the Ming Dynasty did not follow up, and no one has realized that artillery also needs to be aimed and ranged.

Artillery firing has a lot to do with the application of trigonometric functions and geometry, so Xu Guangqi's translation of "Geometric Original" is really not because of a momentary interest, and even opened a new school in Shanghai to teach apprentices, teaching people like Sun Yuanhua, but it is a pity that this Xu Ge Lao, who laid the foundation for the natural science of the Ming Dynasty, has passed away, otherwise, Zhu Youzhen's golden finger can be opened even bigger.

The improvement of gunpowder is more realistic and feasible is the paper shell loading bomb, Zhu Youzhen has asked Sun Heding to do it, and then it needs gunpowder granulation, this "Ji Xiao New Book" has been mentioned, for Sun Heding, the difficulty is not great, the entire ordnance institute, the first to put into mass production is the gunpowder paper shell bullet of the gunpowder bureau.

The research and development of gunpowder naturally takes a long way, from pyrotechnic powder to smokeless gunpowder, which requires the improvement of chemical technology, especially the emergence of nitrification explosives. Of course, the ignition material used to fire the musket is also closely related to the improvement of the chemical process.

Wang Gongchang, Zhu Youzhen did not have any clear requirements, he allowed the young and frivolous Sun Hedou to use his young and frivolous thinking to fool around, as long as he could kill people on the battlefield, any croton, sulfuric acid, and mercury could be messed around casually.

As mentioned earlier, the chemical process naturally has to be mentioned by Zhu Youjian for the construction of the Daming Academy of Sciences and the Academy of Engineering.

Theory lays the foundation of technology, and Daming not only lacks professional chemical process research institutions, but also lacks natural science theory establishment institutions.

Zhu Youzhen does not want the social elites of the Ming Dynasty in the future to continue to spend their wisdom on the correct pronunciation of ancient poems.

Spending the spirit of exploring the truth and spending it on mathematics, physics, chemistry and ideological construction may bring greater social significance.

The Daming Academy of Sciences is the center of future theoretical research, the Academy of Engineering is the center of technical research, and there may be a series of universities that do both.

This may definitely put a lot of financial pressure on the Ming court in the future, but the wealth he brought to the Ming Dynasty is also immeasurable.

Nanjing Xuyuan, the former Yongle period of the Han Dynasty Mansion was allocated by Zhu Youzhen to Fang Yizhi to do the base of the Ming Academy of Sciences, these gardens are also in vain, so that it becomes a holy place of learning and does not need to spend money to choose land to build houses.

As for the Daming Engineering Institute, Zhu Youzhen directly requisitioned Wei Guogong's other Ye Yuyuan, with Xu Wenjue as the head of the Academy of Engineering, and temporarily developed cinchona frost here.
