After the battle of leaving the island, the people on the island had a full understanding of their own strength. Because of the killing of officers and soldiers, there was no revenge. The people on the island were not as afraid of the majesty of the court as before. Cheng Pan was satisfied with the change in the spiritual outlook on the island. After being satisfied, he was immersed in the busyness. The population under the jurisdiction was ten times larger, and the newly joined population had to set up management institutions and carry out education. The workshops should be expanded, the village protection team should also be expanded, and the contact systems should be established in various places. Cheng Pan distributed iron tools without hesitation and distributed rations for the collective labor clubs. Now the farmers who had passed the first summer harvest on the island have begun to exchange surplus grain for various industrial supplies. However, the farmers in the new jurisdiction joined, and a small collective commune with ten people in a small group of people still needed a set of free iron farm tools, so the steel industry was still operating at a loss.

It was already September after the initial construction of the system. Cheng Pan finally remembered that he would start building a large number of buildings and come to Pan Technology. That was the toilet.

Cheng Pan's purpose of preparing to build toilets in large scale was not for spiritual civilization construction. In ancient China, a pile of shit was born, and he had to encounter various dangers. First, dogs could eat them, people would shovel them away. If they were really dried, they would be picked up by special people who picked up dung and would be picked up by specialized men to take over the city. They would never form cliques in the city like their medieval colleagues. Since the construction of toilets was not to add cultural points, it was military. That's right, military.

Since Cheng Pan established a pure firearm unit, his disappearance has been used very quickly. This is a must. The newly formed village protection team must try their best to train them in various live ammunition. Therefore, Cheng Pan must pay attention to the feces. For soil accumulation, Cheng Pan only saw from the book that he first dug out the feces in the toilet and piled up the feces, then placed them on an open space, and then took out the soil and salt, heated it with wood ash at an 8 to 1 ratio, filtered the nitrate water with charcoal, and then boiled until it was viscous, waited for it to cool, and took out the crystals. It was simple, but it was difficult to do. First, how long does the feces piled up?

After a while, the earth nitrate will produce, and what will the earth nitrate look like. Cheng Pan has practiced it many times, but it almost tasted the taste with his mouth. People on the island were very confused when they saw their Mr. Cheng and the manure screaming. Various rumors about Cheng Pan were circulating. After two months, Cheng Pan finally tried a set of processes, but the output was still very high, and he barely produced a ton of nitrate in a month. It was completely in line with Cheng Pan's concept of mass production. In order to save gunpowder, Cheng Pan had to stop the initial crazy live-fire training method and re-establish live-fire training to 60 rounds per month.

In October, Cheng Pan was finally liberated from the pile of feces and assigned the saltpeter to a group to do it. This was a chore. In order to prevent the saltpeter team from being passively slackened, Cheng Pan specially equipped them with leather gloves, protective clothing and masks sewn with oil cloth and oil paper, gave them high salaries, and distributed soil soap made of oil and wood ash, which finally ensured production.

The shortage of gunpowder allowed Cheng Pan to maintain the musket team at 500 people. However, Cheng Pan did not stop developing more powerful weapons.

Of course, the God of War artillery will not be missed by Cheng Pan. The artillery performance that Cheng Pan pursues is not developing towards large-caliber ammunition, but pursuing mobile infantry artillery. Cheng Pan feels that his current strategy of building an army is like that of the little Japanese. All weapons are limited by resources. Large weapons are developing towards lightweight. If not, Cheng Pan does not need heavy artillery, because the Chinese city walls are different from those of the medieval European city walls. China's city walls develop in a thick direction, which is different from the tall West.

The stone castle. In the era of black gunpowder, the effect of relying on cannons alone was not great. Of course, if it was more than twenty heavy artillery fired 10 kilograms of iron eggs, it was another matter. Yangzhou was knocked out by such powerful firepower. Cheng Pan did not have such powerful firepower, and even with such resources, it would not be so irrigated. Cheng Pan decided to follow the method of the Taiping Army attacking Nanjing in siege, that is, tunnel excavation and blasting. What Cheng Pan now needs is the mobile infantry cannon that can suppress the opposite cluster.

Cheng Pan re-entered the iron plant and decided to develop a suitable artillery. Cheng Pan was self-aware and did not use too advanced artillery, but first of all, it was a front-mounted one.

Cheng Pan was preparing to cast iron cannons, so Cheng Pan used the iron casting cannon method. The specific process was to first make a cannon in sections with gypsum, then cast the iron cannon section by section, and finally combine the iron cannon. Before pouring, painted with wood ash and clay added water to the surface of the iron cannon, and then apply the second layer of paint made of extremely fine coal powder. Finally, casting. This practical activity, Cheng Pan bumped and bumped as usual, but the problem was quickly solved. Because Cheng Pan found two bell casting craftsmen, who had many years of work experience in casting large metal devices, combined with rich experience and accurate vision, the cannon was quickly made. In addition to using the iron cannon method, Cheng Pan added a rotating concave and convex ridge line to the iron cannon mold in the cannon bore, and rotated and twisted out when the cannon cooled, so that the rifle could be generated. Cheng Pan also put effort into cooling the cannon,

For this purpose, Cheng Pan specially made a long and multi-section sprayer, in order to make the internal and external cooling time of the barrel bore the same. After manufacturing a few scraps, Cheng Pan finally recorded the best data of each process. The first batch of five cannons were manufactured. This type of gun weighed one ton and fired five kilograms of special iron bullets, with round shapes, but pits of the same size and depth were evenly arranged in a circle of the bullet body to adapt to the rifle in the gun body.

, but hit the target at 2,000 meters. It was not that Cheng Pan did not want to make a shell with the appearance of Minnie bullet, but that Cheng Pan had not yet created a shrapnel bullet and had insufficient lethality with Minnie bullets, and it was not at a disadvantage in the range anyway. After many test shots, Cheng Pan calculated the reasonable charge of the cannon and the firing distance between the shells. He created a supporting elevation sight and arranged the remaining four cannons (one was damaged by a destructive experiment) at Cheng Pan's factory.

Looking at the saltpeter consumed by the cannons bit by bit, Cheng Pan felt a pain in his heart. He was not ready to manufacture a new type of artillery. The fixed-type artillery was named a Type 1 artillery by Cheng Pan. The Type 1 artillery also stopped production after twenty of the production, mainly because the ammunition could not be afforded.

Now all these twenty guns are sealed and not equipped with the village protection team. The reason is that they are also unaffordable. Cheng Pan just selected ten people from the village protection team for gunner training.
