Release that Witch Chapter 160: Fighting

Roland has long conceived bullets for revolving firearms. Round lead bullets and bulk gunpowder are too backward. Taking into account the processing capabilities of Anna, it is technically feasible to directly manufacture copper shell fixed ammunition. The key is how to ignite the black gunpowder filled in ammunition case without situation with a reliable bottom fire.

The bottom fire of early metal shell fixed ammunition is generally mercury threonate that is extremely sensitive to impact. Pull the trigger to trigger the firing pin, which will cause the mercury bottom of the bullet to ignite, which will ignite propellant and shoot the warhead out of the barrel.

Unfortunately, he did n’t think about the kinds of raw materials needed to make mercury arsenate. Literally, there must be nitric acid and mercury, but the handwritten reaction formula shows that these two substances The reaction only produces nitric acid * mercury.

Also, knowing the raw materials does not mean that the finished product can be produced smoothly. Whether the solution has a concentration and temperature requirements during the reaction process and whether a catalyst is required is also a key factor affecting the production of the finished product. Moreover, because of its sensitive nature, mercury thunderate easily triggers an explosion during manufacture, and will lose **** if he is not careful, so he is afraid to try it himself.

So, Roland had to back off. Second, in the case of situation using metal ammunition case, burst ignition is still used. This requires Mars to enter the interior of ammunition case and ignite gunpowder. So firstly, holes must be left at the bottom of ammunition case, and gunpowder should be prevented from leaking out at the same time.

Obviously there is an irreconcilable contradiction between these two points: the larger the opening, the faster gunpowder leaks. And if the opening is too small, it will be difficult for Mars to shoot out of gunpowder.

He needs something that can be successfully ignited by Mars, while blocking the openings to prevent gunpowder from leaking.

Roland The first thing that came to mind was Nitrocellulose, which is commonly known as cotton.

This is one of the few chemicals he remembers that can be used for weapon because its preparation material is very simple: cotton can be immersed in a mixed acid solution of two strong acids. Acid is the most commonly used sulfuric acid and nitric acid, and it is not dangerous to prepare. He originally wanted to wait for the recruitment of alchemist before conducting trial production of cotton, but now that he has made a seven-day appointment, he has decided to roll up his sleeves and end in person.

Lifting the quill, he writes his long-awaited ideas on draft paper.

The first thing is cotton, it's better to be woven and undyed gauze. Many things have been moved back from Duke, and now they are piled up in the castle warehouse. Cotton yarn needs to be degreased, otherwise the oil on the surface will hinder the nitrification. Most of the things that remove grease are transmigrator, which is familiar with sodium hydroxide, also known as caustic soda. At the same time, it is also the raw material for making soap: the joining sodium hydroxide solution in the fat is stirred and put into the mold to solidify, and the soap for washing can be obtained. But Roland has been busy developing industry and agriculture and fighting foreign enemies, and has no time to develop such daily necessities.

As for how to prepare sodium hydroxide, the simplest is probably electrolytic salt water. So the prince discovered that in order to create a new bullet, he first had to start with a DC generator.

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

Ash walked on the side of Scarlet Water River.

Since those witchs knew that she was here to persuade the Cooperation Association sisters to leave Border Town, their attitude towards her also cooled down, and she no longer had the enthusiasm when she first met last night.

Also, she noticed that most witch would practice their abilities in the castle backyard, which shows that Roland also found a way to avoid suffering from magic power phage. Originally, I wanted to use this crucial important information for witch's goodwill, and I had no other choice but to explain the advantages and disadvantages to them separately and persuade them to leave.

What surprised Ash most was that Roland Wimbledon didn't change much in appearance, but he had an indescribable temperament between his hands and feet, which was inconsistent with the image of his former sister-in-law.

Why is this happening? He used to be an incompetent man. When he encountered something, the first thing he thought of was escape, not to mention standing up for others. Even for what he did, he was afraid to take responsibility. Thinking of that harassment, but a disgusted look made him fall to the ground in panic. Tilly heard the news, but he lied that he accidentally fell and blamed Fifth Princess, why did he want to find such an ugly woman as a guard.

Since then, Ash's perception of Fourth Prince has dropped to its lowest point.

I thought that such a person could be better solved, but today's negotiations she did not have the upper hand at all, especially after the other party said that the one-on-one test, she found that even using military force intimidation would not work because The other party did not evade blame, but intended to confront answer's own doubts in a trial manner. At this time, he threatened him personally, except to reduce the goodwill of witch, there is no other use.

Ash sighed. It would be nice if she could be as clever as Tilly. Any problems will be solved in front of her. If she encounters this kind of situation, she must be able to come up with a solution? The ease and anticipation of the arrival have disappeared. If it is not to help Tilly as much as possible, Ash really wants to board the ship to Port of Clear Water immediately and leave Greycastle as soon as possible.

Unconsciously, she found that she had stepped out of the small town range. The other side of the river was no longer a lush wheat field, but a forest land that had not yet been cleared.

Just as Ash was about to turn around, there was a sudden wave of magic power behind her. She subconsciously tilted her head, pierced a dagger from her cheek, and then swept across. The surging magic power has turned into a huge wave. Ash feels that he has been stabbed with pain in half of his cheeks. 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 swept from her eyes, and forced herself to shoot out with one foot.

However, the other party disappeared out of thin air, and appeared again behind him in the blink of an eye. Ash didn't even see how the other party moved.

She pulls out the giant sword, and her body rotates once, causing sword edge to make a dull whistling. The speed is so fast that a large amount of dust is raised on the ground. No dead angle attack can relieve any threat within the blade's attack range, but this trick is invalidated in front of the opponent's weird body style, and the giant sword swept over the shadow position as if nothing had been encountered.

Oops, she thought to herself that her muscles were tight and she was about to eat the opponent's next attack, and the shadow disappeared from her. The dust slowly fell to the ground, and the man was standing not far from her, playing with the dagger in his hand.

It is Nightingale.

"Is this a warning?" Ash frowned.

"Of course not," she put her dagger in her waist, "I just want to see the strength of Exceed."

"Really? I thought you wanted to say"

"Let you quickly leave Border Town, or you will be rude to you?" Nightingale interrupted, "In that case, what is the difference between me and Cara."

Cara? Why did she mention the former leader of Cooperation Association? Ash thought puzzled.

"You can safely persuade each sister. If someone is willing to leave with you, I think His Royal Highness will not stop you, and of course I will not. But ..." Nightingale paused, "Do n’t try to hurt or threaten Your Highness Roland, otherwise Next time, I won't be deliberately offended. "Speaking here, she grinned and disappeared into the air," Enjoy life in Border Town's. "

Sure enough, let me warn myself, Ash shook his head. (To be continued.)
