Back in the office, Roland immediately began to draw the new machine. Pen Fun Pavilion wWw. ｂiquge。 ｉｎfo

He was not idle during the days when the First Army and the witches were on their way to the royal capital, on the contrary, Roland felt that he was a little busier than ever. Even when the nightingale is not around, there is very little time to spend alone with Anna. In addition to housing a shipload of fugitives, he also had Anna work with Lucia to test the composition of the smelting products and build new smelting furnaces.

In the past, whether it was iron or steelmaking, it was carried out purely by experience and feeling, and it was not known what was contained in the smelted things, but now with the help of Lucia, Roland finally had the method to accurately determine the composition of metal ingots. With the help of the decomposition of the substance, he can repeatedly compare and obtain the detailed data required for smelting, such as the mixing time after melting, the specific amount of charcoal to be added, and whether to incorporate additives such as limestone to remove sulfur and phosphorus, or other metal raw materials to obtain alloys......

Based on these data, Roland DG can standardize the process of the smelting industry, obtaining the same quality of iron ingots or steel in multiple productions, and at the same time dispel the fog of materials technology little by little.

And the new smelting furnace was also built for this purpose.

It is a square furnace four meters long and wide and two meters high, with a bottom sloping towards one end. The thick shell is cast iron and covered with clay bricks, as well as Soroya's earth-coated earth, which is extremely heat-resistant. The lowest end has a movable gate, which is pulled by a steam engine. Considering that none of the high-level heating methods, such as oxygen blowing and electric arcing, were ready to be implemented, the furnace was not equipped with any combustion device at all, it relied entirely on Anna's black fire to smelt molten steel. After the raw materials are added according to the tested ratio and the smelting is completed, the molten steel is discharged directly from the tail gate.

The furnace can produce about 50 tons of molten steel at a time, and Anna can complete the smelting in just a quarter of an hour, plus the feeding and tapping time, it is only about half an hour, and the output can basically meet the current production of firearms and artillery. The town's smelting model now is that blast furnaces and shaft furnaces are responsible for producing large quantities of pig iron, which can be used for the manufacture of daily iron and steam engines, and can also be used as a raw material for further smelting by iron furnaces to make wrought iron or steel.

......

Roland is currently drawing a design for a set of production equipment for bullet stamping - with a stable and reliable source of steel, the processing and assembly of stamping machinery no longer has hardware difficulties, and the successful trial production of mercury thunderate makes the mass production of new bullets even more urgent. Although Anna's black fire cutting is efficient and accurate, it still takes a long time for one person to complete a full set of processes, and if the press assembly line is put into production, more than 30 ordinary people can operate it after training, and at least tens of thousands of rounds of ammunition can be produced a day, and the soldiers no longer need to manually reload ammunition.

After dinner, I drew for a long time, until the midnight bell rang outside the window, and the whole set of sketches was considered. Of course, this is only the most preliminary conceptual design, and he doesn't know if some details are feasible, and he still needs to test it before it can be finalized.

In normal times, Roland would have yawned a lot, but today he was in high spirits and didn't feel sleepy at all.

Putting away a dozen pieces of scratch paper, taking out the parchment attached to the letter of the Five Kings from the drawer, and spreading it out on the table, he finally waited for the long-awaited part—the selection of visiting witches.

The list lists about sixty auxiliary witches' abilities, and from Maisie's mouth, the total number of witches on the Sleeping Island should be around two hundred to three hundred, and it is clear that Tilly does not list all the abilities of auxiliary witches. This is also in line with a leader's approach of reaching out for friendship rather than leaving the family in the tray. The other party can do this, which is enough to express the sincerity of the alliance, Roland put on a new candle and concentrates on checking the witch abilities on the appendix.

It has to be said that it was a very difficult choice to decide, and after many comparisons, he selected a list of five visitors.

Roland then spread out a piece of parchment and began to write a reply.

Dear sister, it's a pleasure to hear from you.

I am very excited and relieved by your decision, and with your help, I am more confident that I will be able to block the attack of the church.

I was able to gain the trust and support of the witches because of this - in the entire Grey Keep continent, only the border town has completely erased the influence of the church, and the natives not only accepted the witches, but even fought side by side with them, from defending against evil beasts to fighting against the church, my people and the witches formed an inseparable whole. Now, they can be seen all over the town, and the steam engine that makes you curious is also realized with the help of witches. It's a good sign, and all I'm going to do is spread it across the West, and to the kingdom.

To do this, I must destroy the whole church, let the statement that witches are evil ones turn into dust, and save all the people from folly and ignorance. It's been a long process, and I need more assistance from you.

As for what made me make this decision, and what made me stop being as indifferent to everything as I used to, these trivial matters can be explained slowly when there is a chance, and the content of the letter is limited, so I will not repeat it.

I'm looking forward to the witches' visit next month. Don't worry about safety, I've planned a direct route for them to the border town, completely avoiding the eyes and ears of the church, and without resorting to any port. The only risk is sailing, but I think with Maisie leading the way, the chances of the ship getting lost are slim to none. I will attach a map of the specific route and send it to Sleeping Island with Maisie.

After these witches arrived in the border town, they were naturally able to participate in the teaching of the basics - the so-called knowledge promotes the evolution of witches' abilities, and I am more inclined to deepen my understanding of the world that leads to their transformation, whether it is nature, magic, and self-understanding, it is included. There's no doubt that with every witch whose abilities evolve, we have a better chance of fighting the church, and that's exactly what I agree with you.

Finally, I have put together a list of five selected witches in the hope that I will soon meet them.
