Determined the position of the Shi family in this great era, Shi Fu handed over the military power to Zheng Chenggong as promised, leaving only a few sea ships and pro-credit to engage in maritime trade. Shi Fu's attitude made Zheng Chenggong's original displeasure disappear, and the construction of the mansion was handed over to a cronie, Zheng Chenggong set off to return to Chaozhou Mansion, and even the Shi brothers also set off to return to the front of the Zuo Xianfeng Town Army.

Before leaving, Shi Fu had a secret conversation with Shi Lang, commenting on the generals under Zheng Chenggong, and when Chen Kai was mentioned, Shi Lang gritted his teeth and was very hostile. But Shi Fu didn't care about this, but focused more on Ke Chenshu.

"Zhang Jin and Chen Hui are all old acquaintances, and I can't be clearer about how good they are, so I don't need to worry about it. As for that civil official, I've met him a few times in the past few days, and he's a tough guy to deal with. But he is a civil official after all, and you don't need to pinch him to the death, which will only make the family more dissatisfied with you. If you must fight with them, it is better to give some hints to other civil officials and instigate them to fight each other, which is more decent than you always end up in person. ”

Before Zheng Chenggong set off, the Ordnance Bureau's work of replicating the spirit gun had the first batch of finished products. At the weapon test site outside the city, Chen Kai stroked the sound of the replica cannon, compared to the spirit gun, it was exactly the same, and even the scratches on the cannon sound were copied.

In this regard, Chen Kai didn't know whether to say that they kept improving, or whether to say something else. Fortunately, these unnecessary things did not consume too much labor, and Chen Kai turned a blind eye.

"It's really exactly the same, try the cannon and see the effect."

After taking a closer look, Zheng Chenggong let out an exclamation that was the same as Chen Kai. The replication was successful, and it is said that the effect of the test shot is also good, but after all, this is a copy of the spirit gun, Zheng Chenggong always has an extra thought, and the psychological estimation of shooting accuracy is inevitably higher.

Zheng Chenggong gave the order, Chen Kai waved his hand, and the carefully selected artillery team took the order and began the work of loading and aiming.

Just like the test firing outside Jieyang County, the artillery commander fiddled with those few measuring tools, and the gun gauge, gun ruler and degree plate were all copied according to the matching of the spirit gun, and the accuracy of the artificial construction was extremely high, as for the telescope, it was exchanged for the right use from the water division, because Chen Kai's Ordnance Bureau did not have the ability to independently produce telescopes now.

While fiddling with these eating guys, the gunner commanded the gunners to constantly adjust the direction and angle of the artillery. When the angle was determined, a gunner brought a cloth bag from the side, and as soon as he pulled the thread, the cloth bag opened a hole, and then poured the black things inside into the artillery.

"Packs?"

Seeing that the gunner who loaded it didn't even measure the amount of gunpowder, and poured the gunpowder in the cloth bag almost brainlessly, Zheng Chenggong was stunned for a moment, then turned his head and said to Chen Kai this "question" that had actually been confirmed by him.

"It's a fixed-pack pack."

Chen Kai nodded, he was not too surprised that Zheng Chenggong knew this kind of thing. In the final analysis, there is nothing strange about it, just like the proportion of gunpowder and the technology of granulated gunpowder, the fixed powder package has also been put into use in the Ming Dynasty, but this invention that increases the rate of fire is not small, and has no technical content at all, but finally disappeared in the smoke of the Ming and Qing dynasties.

The replication of the spirit gun made Chen Kai determined to implement the fixed medicine pack. In his opinion, it is undoubtedly necessary to spend more cloth than to speed up the firing, even if the Ordnance Bureau accepts orders for military uniforms from Zheng Hongkui and Zheng Cai, and the cloth is already tight.

The gunpowder was filled, the cannonballs were put in, and the final preparations were over, and when the order was given, the replicas of the three spirit guns erupted in turn.

The hillock at the location of two miles was specially measured distance, and the cannonballs whistled by, hitting the hillock one after another, and then through the telescope of the observation effect, Zheng Chenggong had already shown a satisfied smile without the need for an observer to report.

"No matter how difficult things are, once they are in the hands of the people, they can always give me a satisfactory result."

From one spirit weapon, after a few months, it has become four, and once Zheng Chenggong thought that this kind of "artifact" could be copied in batches, the excitement arose. In this regard, Chen Kai doesn't think it's a big deal, industrial production, in the final analysis, is the volume, but the current casting cannon industry is still a handicraft method, the speed can not be compared, but the manual accuracy is very terrible, copying a front-loading smoothbore gun, even if it is a 24-pound Hongyi cannon, in fact, it is not an incompleteable feat.

"The country's surname is too prestigious, and the lower officials just assign the tasks, all of which are the credit of the craftsmen in the casting workshop, especially the old master, the craftsmanship is really not to be said."

"Chengcheng is always saying that I have a reputation, aren't you being too humble?" Holding down Chen Kai's modesty with a smile, Zheng Chenggong then asked, "What is the speed of such a copy?" ”

Fortunately, the Linggong is a bronze cannon, and China's copper casting technology has always been developed, and the output and quality are worthy of recognition, Chen Kai quickly gave another answer that made Zheng Chenggong very satisfied. Subsequently, taking advantage of Lao Zheng's excitement, Chen Kai took out the matter of the fixed medicine package.

"It's easy to do. However, at this stage, it is still limited to those large-caliber Hongyi cannons, if each cannon has to be loaded with a medicine package, too much cloth consumption is one of them, and it will also cause inconvenience in transportation and storage. ”

In just a moment, Zheng Chenggong thought very carefully. But for Chen Kai, he is already satisfied, because he knows very well that no matter what kind of reform, if the step is too big, it will be an egg, and it must be done step by step. As for the benefits of the fixed medicine pack, anyone who has used it will understand that it is only a matter of time before it is fully rolled out.

The first batch of replication work of the spirit gun was successfully completed, the master is really the master, life experience has given him a certain degree of prediction of the future, as the spirit gun was determined to be able to carry out a more perfect copy, he unexpectedly put into a new round of replication work, and it is continuous.

To put it bluntly, the first half of his life can also cast a variety of different models of artillery, with different levels of freshness, but the second half of his life has been limited by Zheng Chenggong and Chen Kai to the 24-pounder Hongyi cannon of the Linggong model, which is boring and boring.

The "tragedy" of the second half of this master's life, Chen Kai plans to dilute it with white silver, and he firmly believes that in front of silver, all this is nothing. However, the tragedies that have occurred in Guangdong, Guangxi, Huguang, and even the whole of China are not so simple that they can be eliminated.
