Release that Witch

160. Chapter 160 confrontation

    Roland’s bullets on runner firearms have been conceived for a long time. Round lead and bulk gunpowder are too backward. It is technically feasible to manufacture copper shell-mounted ammunition directly considering Anna’s processing capabilities. The key is how to ignite the black gunpowder filled in the ammunition case without a reliable bottom fire.

    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 mercury sulphuric acid 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 these two substances will only react. Produce 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 characteristics, 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 the metal ammunition case, the chirp ignition method was still used, which required Mars to enter the ammunition case and ignite the gunpowder. So first the hole must be left at the bottom of the ammunition case, and the gunpowder should be prevented from leaking out.

    Obviously there is an irreconcilable contradiction between these two points: the larger the opening, the faster the gunpowder leaks. If the opening is too small, the Mars shot by the meteorite will be difficult to ignite the gunpowder inside.

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

    Roland first thought of Nitrocellulose, also known as fire cotton.

    This is one of the few chemicals he remembers that can be used for weapons – because it is very simple to prepare: cotton is soaked in a mixture of two strong acids. Acid is the most commonly used sulfuric acid and nitric acid, and there is no danger in preparation. He wanted to wait for the recruitment of alchemist before the trial production of 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 cotton yarn that has been woven and undyed – this thing has moved back from Duke 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 familiar to you, namely sodium hydroxide, also known as caustic soda. At the same time, it is also the raw material for the manufacture of detergent: Joining sodium hydroxide solution into the grease, 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.

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

    Ash walked on the side of Scarlet Water River, feeling a little faint.

    Since those witches knew that her purpose in coming to this was to advise the sisters of the Operations Association to leave Border Town, her attitude towards her also cooled down, no longer the enthusiasm she saw last night.

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

    What surprised Ash most was Roland Wimbledon. He didn’t change much. He had an indescribable temperament and was incompatible with the image of the former dude.

    Why was? 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 Fifth Princess, why should I find such an ugly woman to be a guard.

    Since then, Ash’s perception of Fourth Prince has been reduced to a minimum.

    I thought that such a person could solve it, 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 work with the military force. The other party did not escape the blame, but intended to answer their own questions in a positive way. At this time, threatening him personally, in addition to reducing the goodwill of the witch, there is no other use.

    Ash sighed. If he could be as smart as Tilly, any problems would be solved in front of her. If she encountered such a situation, she would be able to come up with a solution. The ease and expectation of coming is gone. If you don’t want to help Tilly as much as possible, Ash really wants to take the boat to Port of Clear Water and leave Greycastle as soon as possible.

    Unconsciously, she found herself out of the scope of the small town, the river is no longer a lush wheat field, but a forest land that has not yet been reclaimed.

    Just as Ash was ready to turn back, there was a sudden surge in magic power behind her. She subconsciously turned her head, a dagger pricked from the cheek, and then crossed the road. The surging magic power has turned into a huge wave, and Ash feels that his cheeks are being 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 once again appeared behind his own eyes, Ash did not even see how the other party moved.

    She took out the giant sword, and the body rotated a circle, driving the sword edge to make a dull whistling, and the speed was fast, which caused the ground to raise a large amount 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 Nightingale.

    “Is this a warning?”Ash frowned.

    “Of course not,” she will beheading the waist, “I just want to see the strength of Exceed.”

    “Was I? I thought you wanted to say -“

    “–Let you leave Border Town, or you are welcome?”Nightingale interrupted. “In that case, what is the difference between me and Cara?”

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

    “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. ButNightingale paused, “Don’t try to hurt or threaten Your Royal Highness, otherwise I won’t deliberately stab the next time.”Speaking of this, she grinned and disappeared into the air. “Let’s enjoy living in Border Town’s.”

    Sure enough, I still warned myself, Ash shook his head.
