Gao Junshan attaches great importance to the development of the military industry, he is more concerned about the development of the Mini gun, Sun Yuanhua made several Mini guns are failures, either the range does not meet the requirements, or the explosion of the chamber, Gao Junshan analysis, or the reason why the production of raw materials and technology can not be improved, so he decided to suspend the development of the Mini gun, and wait until his iron factory can produce a large amount of steel, and then put on the Mini gun.

In Xiangwang's Mansion, Gao Junshan put all the factory headquarters of several factories he was planning to build in Xiangyang Mansion, so that he could give timely guidance if there were problems, especially the Ministry of Military Industry.

The Ministry of Military Industry is a new organization set up by Gao Junshan in order to adapt to the current situation, and it is a management organization specifically responsible for military production, and its function is not only to manage the craftsman's workshop, but also to manage the newly built mines, shipyards, iron works, weaving factories, and fertilizer factories that Gao Junshan has put under the management of the Ministry of Military Industry.

The members of this Ministry of Military Industry are all Chongwen disciples, and Gao Junshan himself is in charge of the minister, and it consists of: Gun Department, Vehicle and Ship Department, Mining Department, Iron and Steel Department, Logistics Department, Medicine Department, and Bridge Construction Department.

It can be seen that this military industry department has the characteristics of being ahead of the times, and it is a functional unit founded by Gao Junshan according to actual needs.

Director of the Gun Division: Wu Bei, concurrently the right attendant of the Ministry of Industry;

Director of the Department of Vehicles and Ships: Li Yuanli, concurrently the right waiter of the Ministry of Industry;

Director of the Department of Mining: Ma Kongjian, concurrently the right waiter of the Ministry of Industry;

Director of the Iron and Steel Department: Lv Heju, concurrently the right attendant of the Ministry of Industry;

Director of the Logistics Department: Fang Tingjian, concurrently the right waiter of the Ministry of Industry;

Director of the Department of Medicine: Wang Chenjin, concurrently the right waiter of the Ministry of Industry;

Director of the Department of Bridge Construction: Zhang Sanzhuo, concurrently the right attendant of the Ministry of Engineering.

These seven directors are all proud protégés of Gao Junshan. He knows very well that if he wants to enter the era of hot weapons ahead of time, he must have a certain industrial base to support it, and he wants to build some basic industries in Xiangyang, provide high-quality resources for the military industry, and send his proud protégé to operate the infrastructure of Xiangyang, and he is very relieved.

……

One day, Sun and Jing rushed to see Gao Junshan.

"King Qin," Sun Hejing reported to Gao Junshan with a spring breeze on his face, "our field artillery test firing has been successful!" ”

This is great news, Gao Junshan excitedly shook Sun Hejing's hand and said, "Great! That's great! It's really a tiger father without a dog! The back waves of the Yangtze River push the front waves. The field artillery test was successful, tell me how you did it. ”

Gao Junshan was a little incoherent with excitement.

Sun Hejing said: "If the King of Qin wants to know the details, you can go to the treasury with me to have a look, and I will report to the King of Qin in detail there." ”

Gao Junshan said happily: "Go to the warehouse, go to the warehouse." ”

The warehouse where the field artillery is stored is not far from the Xiangwang Mansion, and the two took a four-wheeled carriage to the warehouse where the field artillery is stored.

As soon as you enter the warehouse, what is displayed in front of Gao Junshan is a row of nine field guns, the reason why it is called a field gun, is because it is a light artillery, which is convenient for sports and combat, and Gao Junshan visually measured that it weighs about 300 catties.

Sun Hejing introduced: "We borrowed the design concept of 'swarm bees' to transform the Franc machine into its current appearance, don't look at it bulky, it is the same as 'swarm of bees', it is also divided into two parts, the gun mount and the barrel can be separated, so that it is convenient for field combat." ”

Gao Junshan asked with concern: "How is its stability?" The recoil of the artillery is very strong. ”

Sun Hejing said confidently: "King Qin, please rest assured, you look here," he pointed to the connection between the base of the gun and the barrel, "The joint of the two parts is stuck with a barb, and after test firing, the stability is good." ”

Gao Junshan approvingly: "You have done a good job, ten times better than your father." ”

Sun Hejing was very modest: "This is inseparable from the guidance of King Qin and the teachings of my father. ”

When Gao Junshan heard Sun Hejing say this, he was very complacent, and he said flutteringly: "The son can be taught." ”

"King Qin, I haven't talked about the power of field artillery yet!"

Gao Junshan was very curious: "Is there anything else I don't know?" ”

Sun Hejing smiled proudly: "You taught me the principle of flowering shells in class, and I will use flowering shells on these cannons now." ”

The surprise in Gao Junshan's heart could not be described in words, and he was eager to know how his student Sun Hejing made the flowering bomb.

Sun Hejing didn't wait for Gao Junshan to ask, so he took him to another warehouse, where the guards were even stricter, and there was a sign at the door of the warehouse that said 'No Fireworks', it turned out that this was Sun Hejing's powder magazine.

Sun Hejing took out a flowering bomb and told Gao Junshan: "King Qin, look, this is the flowering bomb I designed, it is very similar to the 'swarm of bees', and it is also a second-level propulsion. ”

Gao Junshan took a closer look, and sure enough, it was divided into two parts, the rear propulsion part was a pure copper shell, and the explosive warhead in the front was cast iron, Gao Junshan asked: "How did you connect copper and iron together?" ”

"King Qin taught us in class that copper and iron can be welded together with tin," Sun Hejing explained, "when the cannon is fired, the shell is in the process of flying, due to the high temperature generated by combustion, the solder will melt, so that the thruster and the warhead will be separated, and at the same time of separation, the secondary gunpowder of the warhead will be activated, resulting in a secondary explosion, and the warhead will gain thrust again, and at the same time, the fire rope leading to the bomb compartment of the warhead will be ignited, and since the time to the landing place after the secondary explosion is constant, as long as the length of the fire rope is preset, The warhead will be able to explode exactly at the point of impact. ”

Gao Junshan nodded: "This is a good theory. ”

Sun Hejing said: "This is not just a theory, we have successfully exploded in practice. ”

"How's the range?"

"The range can be up to three miles."
