By the fifth day of the agreement, Roland had finally prepared all the ingredients for making cotton wool.

He also made a serious mistake in electrolysis of salt water, using the copper strips left over from Anna's cutting bullet as electrodes, which resulted in the electrodes being dissolved, wasting a basin of brine - because the electrolyte was generally saturated salt water in order to avoid chlorine dissolving in water, and salt was not considered a cabbage price in this era. Therefore, when he poured out the waste brine that was infused with copper ions and caused debris precipitation, Roland felt that he had thrown away several golden dragons in vain, and finally replaced the electrodes with carbon rods to solve the problem.

After boiling caustic soda with water to remove grease and obtain absorbent cotton gauze, he took the rest of the caustic soda with him to the chemistry lab.

The esterification of the cotton wool is the most important step in the production process, and he does not know the principle, only that the gauze should be soaked in a mixed acid solution, and it can be taken out after the nitration is complete. The solution ratio and reaction time are unknown. Roland asked Caimer to divide into several groups to experiment, using hourglass to control the time, soaked small pieces of gauze repeatedly washed with water, and then soaked in sodium hydroxide solution to reflect off the excess acid, and the wet finished product was transported back to the castle and handed over to Wendy to dry.

Due to the use of fuming nitric acid with a high concentration during esterification, most of the sample products can be ignited quickly, and one part nitric acid and two parts of sulfuric acid are soaked in the best effect of the cotton wool. Once the rough recipe was obtained, the lab began mass production - the soaked and washed cotton wool was immediately transported by the soldiers of the First Army, and even the chief alchemist did not know what they were doing for it.

The air-dried gauze was cut into fingernail-sized squares by the maids, packed into boxes and sent to the North Slope Mountain, where they were finally filled in the backyard of the firing room. In the absence of machine assembly, this process can only be completed by human labor. A group of guards sat down in dispersion, gently poked the glue-stained cotton gauze into the bottom of the shell with a wooden stick, sealed the ignition hole, and then poured the granular black powder into the shell with a funnel, compacted in layers, and the loading amount of each piece was as consistent as possible.

The last step is to press the bullet, and the warhead processed by Anna fits the shell very well, and it can be gently tapped with a hammer after being pushed in with her bare hands.

The efficiency is a little low, but it can produce more than 100 rounds of ammunition a day. By the sixth day, Carter had finally used his new weapon. As the chief knight with excellent physical qualities, his shooting rate has been greatly improved after a few days of repeated practice, which is completely different from Roland's target shooting performance during military training.

After changing to flintlock fixed ammunition, Carter finally did not have to hold the musket in a strange shooting posture with his wrist drooping, as long as the sealing cotton did not break, the bullet nest could be kept clean, and at the same time, it was several times more sensitive to Mars than black powder, and the firing rate was also guaranteed.

On the last day, Roland had Carter Lannis practice rapid drawing and double-gun shooting - the recoil of a 12mm pistol was impressive even with black powder, and it was difficult to ensure the accuracy of the second shot with one hand, but in Roland's plan, it was a backwater counterattack that was accidentally trapped behind the ashes.

Carter will come on with two guns, and in a tug-of-war, ten bullets will be enough to make the difference between victory and defeat, and if he is close in the opening game, he can quickly pull out another gun and fight back. And considering that the opponent's weapon has a certain defensive ability, Roland deliberately chose a steel warhead that is not easy to deform, which increases penetration and reduces the lethality of the cavity. Coupled with the limitations of the smelting technology of this era, nine times out of ten, the ash sword was made of pig iron - the exaggerated shape did not bring about the improvement of quality, on the contrary, the bulky iron weapon was not fully forged, and the internal stress distribution was even more uneven, which could not be called a good shield. According to Roland, the greatsword is at most a tabula rasa weapon, and if the luck is not particularly bad, the probability of ricocheting is very low.

If Ash wants to defeat Carter, he must first get close to the Knight, which is the natural disadvantage of cold weapons against hot weapons. As long as it is not exaggerated to the point of being able to visualize the trajectory of the trajectory and dodge the bullet in an instant, this distance is an insurmountable chasm.

It wasn't until it was getting late that Ash waited for Maisie to fly back to the room.

"Why are you coming back later and later these days?" she asked, closing the window.

"Lightning took me to catch birds," Maisie turned back into her human form and pulled out a roasted bird's leg from her fanny pack, filling the room with the scent, "I left it for you." ”

"I've eaten it," Ash shook his head, "Is Lightning a Commonaid witch?"

"Well," she nodded vigorously, "the ability is the same as mine, and it is also flying, but it is much easier to use." After a pause, she continued, "Sister Ash, do you have to fight this one?" I think...... They won't go with you, and they're good here. ”

Ash was stunned and didn't answer.

"Because even I want to stay here," Maisie said to herself, as she sat down on the bed, "and the bed is soft and the food is hearty." I saw that at lunchtime, the lord set the table in the backyard and ate with the witches after the practice. Everyone talked and laughed, and he occasionally interjected a few sentences, which was completely different from the appearance that other nobles hated. In the afternoon, I was pulled by lightning to play Gwent cards, that is, the two of them drew ten cards and competed with each other, and the final point won by a big point, which was very interesting. They also gave me two decks, Sister Ash, do you want to play one? I'll teach you. ”

"No......" Ash shook his head and took a deep breath. She was aware of the changes in Maisie these days, but it wasn't until this moment that she suddenly realized that her thoughts seemed to have fallen into a misunderstanding.

Most witches make a living in a day of fear, and a stable and comfortable place to live is all they seek. Maisie, for example, spent her nights in a thatched hut in the slums of the royal capital like a real bird, before she was accepted by Tilly. Even when Tilly decided to cross the sea eastward, Maisie traveled from place to place to contact the hidden witches for half a year. I'm afraid it's the first time she's experienced such a comfortable and peaceful life.

It wasn't until she met Tilly that she lived a life she couldn't have imagined. Accustomed to the relative peace of life in the palace, she ignored the significance of the town to the witches - the attraction of home, which was always unparalleled in the eyes of witches. They want to stay here, and they want to protect this territory, probably like they want to protect Tiri......

If Roland Wimbledon could fend off the mad Divine Punishers, as he claimed, it would be a better option than the Fjords - a journey to a completely unfamiliar land to establish a witch kingdom sounds exciting, but no one can predict how much it will actually endure.

But if he can't resist, should the witches leave?

Ash's mood suddenly calmed down.

Thinking about it from another angle, if Tilly can't establish herself in the fjord, I'm afraid I will choose to stand by her side and protect her until the last moment. As the one who gave herself a home, she had no reason to leave first.

"This place is under the threat of the church all the time, and if it can't stop the divine punishment army, it is only a matter of time before the border town will be destroyed. ”

There really is no need for this competition...... Still, she decided to complete it, for the sake of caution, or for proof.

"What if they can stop it?" muttered Maisie.

"I want that too, so I'll help them verify that. Ash said in a deep voice.

She closed her eyes and was ready to give it her all. (To be continued.) )
