Chapter 9 Nitroglycerin
Anne has a lot of experience in the wild, and soon after entering the forest, she found a dry and warm cave, and there was a bear sleeping in the cave, she sneaked into the cave and pierced the bear's brain with a sword.
In the bear cave, except for the fishy smell, there is nothing wrong with everything else, and the bear that was stabbed to death also contributed a warm bear skin.
At this time, Lawson was so tired that he couldn't walk, he was dizzy, he could hardly do any thinking, his eyelids were sinking straight down, and after confirming that his surroundings were safe, he lay down next to the still warm bear carcass, and fell asleep in less than half a minute.
He had a dream.
In the dream, he slept beautifully, and when he woke up, he found that he was lying on the soft bed in the apartment, and the golden sunlight passed through the floor-to-ceiling windows of the balcony, just sprinkled on the quilt, and the quilt was warm and comfortable.
The quilt exudes a warm fragrance, which was just changed for him when his mother came to school two days ago, and when he thinks of his mother, Rosen's mind comes up with her nagging.
'You're such an adult, why haven't you learned to clean up your room, it's such a mess, I see which girl will take a fancy to you.' ’
'Why are there so many fast food boxes?' I'm telling you, it's not good to eat too much of these things! ’
'Rollo, I'll tell you......'
'Mom~I know~' Lawson subconsciously replied, and after speaking, his heart moved slightly: 'Huh~ I'm going back to Earth? ’
Lawson sat up on the bed, turned his head to look around, but as soon as his head moved, he felt a sharp pain on the side of his neck, and subconsciously reached out to cover it, and then looked around carefully, the warm quilt with a fragrance turned into a bear corpse with a strong smell, the golden sunlight in the dream became a small bonfire, and the apartment in the dream became a dark and narrow bear cave.
A deep sense of loss welled up in Rosen's heart: 'I disappeared suddenly, and my parents must have gone crazy.' And grandma, she's almost 80, but I can't let her know about me. ’
His mind was still in a dream, and his mind was constantly swirling with all kinds of past events living on earth, and he was stunned for a while.
"Are you awake?" There was a voice around her, it was Anne the Stalker.
When Rosen came back to his senses, he saw a tall, athletic female pursuer sitting at the mouth of the cave, holding a dagger in her hand, bleeding a hare.
She did it very carefully, and in order to prevent the smell from spreading, she dug a pit nearly 20 centimeters deep in the ground, and threw rabbit blood and rabbit internal organs into the pit, leaving only a rabbit skin.
When the rabbit's blood was gone, she refilled the pit and covered it with fallen leaves and dead branches.
When Rosen saw Anne skewering the rabbit with a fresh twig, and smearing a handful of salt on the rabbit meat, he was about to roast it on the bonfire, so he said: "There is flour in the bag, add some salt water and form a dough, and wrap it in the rabbit meat and roast it together, and the rabbit meat will be very tender and delicious when it is cooked." ”
Anne complied, and at the end she laughed: "After all, it is a rich young master, and he didn't forget to bring delicious food when he ran out." Such fine white flour costs 10 lunts per catty! ”
"Hey, hey." Rosen laughed, not defensively, and asked, "Anne, how are your injuries?" ”
Anne turned her head and smiled at Rosen, the light of the campfire reflected her face, and she was full of light: "It's okay to recover, it doesn't hurt much." ”
"Oh, that's good." Lawson looked at the sky outside the cave, it was still dark, and asked, "How long have I slept?" ”
"It didn't take long, about two hours before dawn, and it was still half a day." Anne said.
"2 hours? The timing was just right. Rosen nodded. According to his estimates, the safe time was only 3 hours, and if the vampire Viken hadn't given up on tracking, he could have come to the door at any time after 1 hour.
There is an hour left in the safe hour, and after 1 hour, the vampire Viken may come to the door at any time.
"Anne, do you still have silver powder in your hand?" Rosen asked, resting for two hours, the effect is very good, although the body has not fully recovered, but it is much better than when he was just sucked blood, although the head is still a little drowsy, but it does not affect thinking.
"And a few more."
"Where's the silver grain?" Rosen asked again.
"There are no ready-made silver nuggets, but there are a lot of silver wolves in the cash box. I can use a dagger to cut out silver grains for you. How old do you want to be? ”
"I don't know how big it will be yet." Rosen gestured with his hand again and said: "I also need a straight bamboo pipe, probably so thick, preferably more than three years old bamboo, there is a bamboo forest dozens of meters away from the entrance of the cave, can you go and help me pick a few?" ”
"Of course that's fine, but you're planning to make a bamboo bow to deal with vampires?"
Rosen smiled wryly: "Do you think the bamboo bow is useful?" ”
"It's useless."
Having said this, Anne put down the rabbit in her hand and walked out of the hole with her sword, and after about three or four minutes, she came back with a few fresh bamboos: "Do you see this? ”
Lawson examined them one by one, and finally selected a bamboo tube with an inner diameter of about 1 cm: "This one is very good, round and straight, and the right size." ”
Anne couldn't understand Rosen's thoughts at all, but she knew that time was running out right now, and the only thing she could do was to help Rosen, an alchemist, do what she could: "Now do you know how big a silver grain you need?" ”
"Well, it's about that big, and it takes about 100 or so. It would be nice if you could round them up. Rosen picked up a pebble from the ground and showed it to Anne.
Anne glared at Rosen: "Rub the round? Silver is not mud, such a hard thing, how can you rub it? ”
She wanted to help, yes, but it was an impossible task.
"Of course, one can't be rounded, but you can rub a dozen or hundreds of them together. It is best to mix some fine sand and polish the surface of the silver beads. "He doesn't have high requirements for the roundness of the silver grains, if it is an ordinary person, it will definitely not be possible, but the mutant hunter's hand strength is amazing, the 30-pound sword is like a toothpick with one hand, and the texture of the silver grain is soft, and it is not a big problem to rub it round.
"Really?" Anne looked skeptical.
"Try it and you'll know."
Lawson himself was not idle, he first put the bamboo pipe on the fire and roasted it a little, and after evaporating some water, the bamboo pipe became a lot harder.
Then, he tore off a long strip of cotton cloth from the cotton underwear he was wearing, picked up the bamboo pipe, and wrapped the strip of cloth around the outer circle of the bamboo pipe one by one, tightly wrapping it in five layers before stopping.
This is done to strengthen the bamboo pipe, so as not to blow up the chamber when it is done.
When he was done, he used a dagger to cut a wooden stopper, wrapped it in a layer of cloth, and tightly closed one end of the bamboo tube. In this way, a simple launch tube is complete.
After making the launch tube, Rosen began to prepare the propellant, which was the most critical step.
Rosen took out two pill bottles from the alchemy room at home, one containing saltpeter powder and the other containing glycerin, he mixed the two bottles together, added some water, and then shook vigorously until the solution and glycerin were completely fused together.
After doing all this, Lawson took a deep breath, gathered his mind, and focused on the solution in the bottle.
'Saltpeter is potassium nitrate, and when dissolved in water, the ionic bonds are broken to become freely moving potassium ions and nitrate ions. Glycerol, the scientific name glycerol, contains three hydroxyl groups. If I could completely nitrate glycerol by replacing three hydroxyl groups in the glycerol molecule with nitrate ions, I would be able to produce a powerful nitroglycerin. ’
Naturally, this reaction is not possible. On Earth, glycerin must be catalyzed by concentrated sulfuric acid to produce nitroglycerin and water with concentrated nitric acid, but now, Rosen has the alchemical talent of 'Friends of the Elements', which is equivalent to having a powerful catalyst.
Rosen held the medicine bottle in his hand, his body motionless, and his mind was completely focused on the solution inside the medicine bottle.
Time passed minute by minute, and on the surface, Rosen seemed to be in a daze, the only change was that his forehead was sweating all the time, and beads of sweat the size of beans kept dripping down.
After about 1 minute, the solution in the vial did not show any change, and Lawson's first attempt failed.
'Whew~Whew~'
Lawson gasped for breath, almost all over his body was soaked with sweat, and white vapor evaporated from the top of his head. In this minute, the alchemy energy he released almost exceeded the energy he had used to control the spread of the mandala poison, but he did not get any effect.
Anne on the side had been paying close attention to Rosen, and when she saw him frowning and thinking, she asked in a low voice, "Can't you?" ”
Rosen nodded slightly: "Hmm~ My method is wrong, I'll think of other ways." ”
