[Author’s Note: There are two types of chain bullets. One is called a light chain bullet. The two iron balls connected by the iron chain are hollow, the firing distance is relatively far, and the trajectory is relatively floating. The other is called a heavy chain bullet. The two iron balls connected by the iron chain are solid, the firing distance is relatively close, and the orbit is relatively stable. Professional navies, such as the British Royal Navy in the 18th and 19th centuries, have clear regulations on the use of light chain bullets and heavy chain bullets.]

"Yeah, very good!"

Zhang Zhun nodded and said in admiration.

At that time, the most powerful weapon must be the Red Armored Cannon. After the Hu Ben Army mastered this weapon, it could make itself stronger. No one ever complained about the number of advanced weapons, especially the navy. It was impossible to challenge the Zheng Zhilong Pirate Group directly, without large gunships equipped with Red Armored Cannons.

After pondering for a while, Zhang Zhun added: "But it is not enough. We must continue to explore the potential of the Red Cannon, reduce the weight, increase the range and rate of fire. It would be even better if the mobility of the Red Cannon cannon can be increased."

Both Sun Qinkai and Mo Ru agreed.

Zhang Zhun asked again: "How is the research on Napoleon's cannon?"

Sun Qinkai hurriedly said, "Sir, please come here."

Zhang Zhun nodded and followed behind him.

The group came to the casting workshop next to it and entered a large house. There were many cannon samples, semi-finished products, defective products, scraps, and all kinds of cannons. Some cannons look very strange, and Zhang Zhun had never seen them. Many cannons have only models for the time being.

Sun Qinkai still worked very hard. Perhaps he had no talent and could not learn without a teacher, but he was absolutely persevering in his research on cannons. Before he studied the Red Cannons, he had been trying to see if other types of cannons could achieve the performance of the Red Cannons. The various cannons placed here are all masterpieces of his research.

Zhang Zhun saw a sample of the Napoleon cannon at a glance. This sample is at the front. Although it is a bit rough, it is undoubtedly a sample of the Napoleon cannon. The cannon car looks like a round wheel, a supporting cannon stand, an ammunition carriage, and a pulling wooden shaft. The Napoleon cannon that Zhang Zhun remembers is not much different from the sample in front of him. It seems that Sun Qinkai and Mo Ru have a strong comprehension ability.

The entire sample is made of wood in a one-to-one ratio. There must be special people responsible for the parts of each link, and it is impossible to assemble them for the time being. Therefore, Sun Qinkai made this sample. According to his estimate, there is no problem in principle and composition. The key now is the parts, especially the material problem of the barrel. The real Napoleon cannon is made of bronze, and Sun Qinkai is currently using steel instead of bronze.

Zhang Zhun circled the sample a few times and said affirmatively: "That's right, this is basically what it looks like."

Sun Qinkai breathed a sigh of relief and said excitedly: "That's good! We will try repeatedly based on this situation until we can be put into use. Li Fenglai is adjusting the quality of the steel. If there is no accident, we may be able to cast the first gun barrel that can be put into use at the end of this month."

Zhang Zhun encouraged, "We Chinese are never inferior to foreigners in mind. We can definitely do what foreigners can do. We don't have bronze, and we can use steel instead. As long as we have good steel, we are not afraid of not being able to cast a good gun barrel."

Mo Ru said next to him: "Sir, give this kind of cannon a better name!"

Zhang Zhun nodded, pondered for a moment, and said slowly: "Ben Lei Cannon... what do you think?"

Mo Ru thought for a moment, and said with a high high, "It moves like a rabbit, and it's like a thunderbolt. I think it's like. What we want is the quick reaction ability of the thunderbolt cannon and the high firing rate."

Sun Qinkai naturally had no objection and thought Mo Ru's explanation was very reasonable, so this copycat version of Napoleon cannon was named the Thunder Cannon. This name is a bit vulgar. Fortunately, the cultural level of the Tiger Ben Army soldiers is not high, and the more popular the name, the better. If you are too difficult to describe, you might not remember it.

Subsequently, Sun Qinkai introduced the design data of the Thunderbolt Cannon in detail. According to Sun Qinkai's design, the caliber of this copycat Napoleon cannon is about 120 mm and has a range of about 1,000 meters. It should not be much different from what Zhang Zhun described. Of course, this is just a theoretical design. In fact, due to the material problem of the design to the barrel, this performance data cannot be considered true at present.

Zhang Zhun was not very concerned about the performance data. The most important reason why he wanted to copy the Napoleon cannon was its good mobility and a complete set of arrangements that could fight anytime and anywhere. It was his original intention to move like a rabbit and a speed of thunder. Simply put, everything should be fast. The movement speed is fast, the firing speed is fast, and the continuous shooting speed is even faster. It would be best if two shells could be fired in one minute.

This is a real field artillery. You can pull it away at any time, stop at any time, and fire it on the spot. Even if you suddenly encounter an attack from the Tartar cavalry in the field, you can fire it quickly. Although the flying dragon cannon and the red cannon may be much higher than the Napoleon cannon in other aspects, it is still impossible to do this.

Considering the speed of the Tartar cavalry, in addition to requiring a quick entry into the combat state, the rate of fire should also be as fast as possible. Therefore, the zodiac code-name shooting method should also be promoted to the Napoleon cannon. As long as everything is standardized, processed, and conditioned reflex, firing cannons does not require passing through cannons at all, and the rate of fire will naturally be much faster.

In the artillery casting factory, Zhang Zhun stayed for two days and studied the problem of counterfeiting Napoleon cannons (Thunderbolt cannons) in detail with Sun Qinkai, Mo Ru and others, and passed on all the knowledge he knew to two people to speed up the counterfeiting of Napoleon cannons.

Two days later, Zhang Zhun returned to the Grand Governor's Office in Fushan City.
