Release that Witch

Roland has long conceived the bullets of the runner firearms. The round lead bombs and bulk gunpowder are too backward. Considering Anna's processing ability, it is technically feasible to directly manufacture copper shell-mounted ammunition. The key is how to ignite the black powder filled in the shell without a reliable primer.

The bottom fire of the early metal shell assembly bomb is generally very sensitive to the impact of mercury sulphuric acid, the trigger is pulled to trigger the striker, and the thunder acid mercury at the bottom of the bullet is activated to ignite the shot and shoot the bullet.

It is a pity that he wants to break his head and can't think of the kinds of raw materials needed to make mercury sulphuric acid. From the literal point of view, there must be nitric acid and mercury, but the handwritten reaction can be seen that the two substances will only react. Produces nitric acid * mercury.

Moreover, it is known that the raw material is not equal to the smooth production of the finished product, whether the solution has concentration and temperature requirements during the reaction process, and the need to add a catalyst is also a key factor affecting the production of the finished product. What's more, due to its sensitive nature, mercury sulphate is easy to trigger an explosion when it is manufactured. If you don't pay attention, you will lose two fingers, so he is too late to try it.

Therefore, Roland had to retreat to the next level. In the case of using a metal casing, the ignition method was still used. This required Mars to enter the inside of the casing and ignite the gunpowder. Therefore, first the hole must be left at the bottom of the shell, and the gunpowder should be prevented from leaking out.

Obviously there are contradictions between the two points: the larger the opening, the faster the gunpowder leaks. If the opening is too small, it will be difficult for Mars, which is shot by Meteorite, to ignite the gunpowder inside.

He needs something that can be ignited by Mars and blocks the opening to prevent the gunpowder from leaking.

The first thing that Roland thought of was nitrocellulose, also known as fire cotton.

This is one of the few chemicals he remembers that can be used in weapons because its preparation is very simple: cotton is soaked in a mixture of two strong acids. Acid is the most commonly used sulfuric acid and nitric acid and is not dangerous when prepared. He wanted to wait for the alchemist to recruit the fire cotton, but now that he has set a seven-day contract, he decided to pick up his sleeve and personally end.

When he mentioned the quill, he wrote the long-conceived idea on the draft paper.

The first is cotton, preferably a textile and undyed thin cotton yarn. This thing has been moved back from the Ducal House and is now piled up in the castle warehouse. Cotton yarns need to be degreased, otherwise the grease attached to the surface will hinder the progress of nitrification. Most of the things that remove grease are well-known, that is, sodium hydroxide, also known as caustic soda. At the same time, it is also the raw material for making soap: adding sodium hydroxide solution to the oil, stirring it evenly and solidifying it into the mold to obtain the soap for washing. Only Roland has been busy developing industrial and agricultural and confronting foreign enemies. There is no time to develop such daily necessities.

As for how to make sodium hydroxide, the simplest thing is to electrolyze salt water. So the prince found that in order to build a new type of bullet, he must first start with a DC generator.

*******************

The ashes walked along the Chishui River, and the mood was faint and somewhat low.

Since the witches knew that her purpose was to advise the sisters to leave the border town, the attitude towards her also cooled down, no longer the enthusiasm she saw last night.

Moreover, she noticed that most witches would practice their abilities in the backyard of the castle, which shows that Roland also found ways to avoid suffering from magical phagosomes. The original plan to exchange this vital information for the good feelings of witches has been shattered. Apart from explaining the pros and cons to them separately and persuading them to leave, they have almost nothing to do.

The most intriguing thing about the ashes is that Roland Wimbledon has not changed much. He has an indescribable temperament in his gestures, which is incompatible with the image of his former nephew.

Why is this happening? He used to be an incompetent person. The first thing that comes to mind when he meets things is to escape. Don't say that he has come forward for others. Even if he does what he does, he is afraid of being responsible. I remembered the harassment, but a disgusting look made him fall to the ground in panic. Tilly heard the sound, but he lied that he accidentally fell, and blamed the five kings, why should I find such an ugly woman to be a guard.

Since then, Ashes’ perception of the Four Princes has been reduced to a minimum.

I thought that such a person could solve it better, but today she could not get the upper hand, especially after the other party said that one-on-one test was conducted. She found that she could not use force to force it because the other party did not escape. Responsible, but intend to positively answer their own doubts in a trial-and-error manner. At this time, he threatened him personally. Apart from reducing the goodwill of the witch, there is no other use.

Gray sighed, if you can be as smart as Tilly, any problems will be solved in front of her. If this happens, she will be able to come up with a solution. The ease and expectation of coming time has disappeared. If you don't want to help Tilly as much as possible, Ashes really wants to take the boat to the clear water port and leave the Grey Fortress as soon as possible.

Unconsciously, she found that she had walked out of the town, and the river was no longer a lush wheat field, but a forest land that had not yet been reclaimed.

Just as the ashes were ready to turn back, there was a sudden wave of magic behind her. She subconsciously turned her head, and a dagger pricked from the cheek, and then crossed the road. The surging magic has turned into a huge wave, and the ashes feel that their half cheeks are stabbed and painful. The coherent moves of the other party are obviously not what ordinary people can do. She no longer hesitated, letting her body fall completely, avoiding the dagger that had been swept away from her eyes, and kicking herself out with one foot.

However, the other party disappeared out of thin air, and appeared in the back of the eye again in the blink of an eye. The ashes did not even see how the other party moved.

She took out the giant sword and rotated her body, causing the blade to make a dull whistling, and the speed was so fast that the ground raised a lot of dust. There is no dead angle attack to relieve any threat within the range of the sword attack, but this trick fails in the face of the strange body of the other side, and the giant sword sweeps over the shadow position, just like nothing.

Oops, she thought to herself that her muscles were tight and she was ready to eat the next round of attacks. The shadow disappeared from her. The dust slowly landed, and the man was standing not far from her, playing with the dagger in his hand.

It is the nightingale.

"Is this a warning?" Ashes frowned.

"Of course not," she will beheading the waist, "I just want to see the strength of the extraordinary."

"Yes? I thought you wanted to say"

"Let you leave the town of Bianbu, or you are welcome to you?" The nightingale interrupted. "In that case, what is the difference between me and Hakala."

Hakala? Why did she mention the former leader of the Communist Youth League? I don’t think so.

"You can safely persuade every sister, if anyone is willing to leave with you, I think that His Highness will not stop you, of course I will not. But..." The night owl paused. "Don't try to hurt or threaten Your Royal Highness, otherwise The next time I won't deliberately stab." She said that she grinned and disappeared into the air. "Let's enjoy life in Bianbu Town."

Sure enough, I still warned myself, Ashes shook his head. (To be continued.)
