The 085th grenade of Lin Tianyu's visit

"Not yet, it's just the shell. The second brother also has to help me find some raw materials. ”

"What ingredients?"

"One nitrate, two sulfon, and three charcoal, their weight ratio is saltpeter 75, sulfur 10, charcoal 15. It's all about grinding. ”

"Oh, what do you want is this medicine? I thought it was a medicine like mine! Where can I buy these things?" Lin Tianyu looked at Leng Xuan and couldn't think of how to buy it for a while, a little confused.

"Go and buy fireworks and firecrackers, as soon as you say that people will know the way, as long as you have money, people will give you as much as you want! This is not difficult, the difficult thing is the ironware, you have to make me three calibers, one inch, two inches and three inches, and a number of cotton paper. ”

"What the hell are you going to do?"

"Then you'll know the way, hahaha!"

"Isn't the fifth brother and sixth sister not interested in my medical skills?" Seeing that the mechanism that Leng Xuan was going to do had little to do with his medical skills and medicinal skills, Lin Tianyu seemed a little disappointed.

"Yes, after this firearms mechanism is done, I will learn medicine from my second brother, and teach me more ways to use poison to prevent poison and destroy poison?"

"I'm the god of medicine, not the god of poison, and I never get those things. Lin Tianyu's face was serious and full of atmosphere, as if he was very clear with things like poison, and when it came to poison, he still looked disdainful.

"If there is no poison, then I will not learn!"

"If you want to learn, you can have a little, but you can't learn too much, you can't ruin my reputation!" Lin Tianyu's face immediately changed, and he seemed to feel a little compromised when he stepped forward.

"Ha Luha, poison - medicine - medicine, poison and medicine are the same thing! I don't think the second brother will ask me to study medicine now, right?"

"No, absolutely not, the most important thing for you now is to cultivate and upgrade to stand, practice the eldest brother's magic skills first, and when you have time, then read the second brother's medical book, not to mention killing people and harming people, at least you can defend yourself and heal your injuries!" Lin Tianyu said and took out a book from his bag, and there was a lot of dirt and powder on the paper, and the words were not clear.

"Alas, no, no, we don't dare to touch the things that the second brother has touched. We don't want to die so fast, haha!"

"Don't worry, this is a new book, I ordered someone to copy it for you, the fifth brother can rest assured that it is absolutely safe!" It's all so dirty, and it actually says that it is a new book, and it can't be believed if it's killed, but Leng Xuan actually wants to learn medicine very much, so he deliberately accepted it very carefully, in fact, he knew that as long as Lin Tianyu was there, it didn't matter if he was poisoned.

"Then second brother, don't you want to learn some of the eldest brother's magic secrets?"

"It's okay to learn a little bit by the way? hehe. Lin Tianyu pretended to be arrogant and said it easily, but in fact, it was difficult to hide his expression of wanting to learn.

"It's a pity that the secret book of magic skills was taken away by my fourth brother, what should I do?"

"Ah!?? how can you give it to him, that's what the eldest brother gave you. Lin Tianyu was obviously disappointed and surprised.

"He's just borrowing books, but if the second brother really wants to learn, it's not impossible?"

"How to learn?" Lin Tianyu frowned, not knowing how to hang his appetite for Lu Dao Leng Xuan.

"I'll teach you, Ha Luha, you can also let the fairy teach?"

"You, will you?" Obviously, Lin Tianyu couldn't believe it.

"Didn't you see that when you first came, we were practicing the 'Clear Stream Sword Technique'? Before learning the 'Clear Stream Sword Technique', we would know the 'Divine Sword Roar', but our spiritual power is too low, and we have no realm and no power. Come second brother, you hurry up and learn "Divine Sword Roar" and go find someone to make ironware for me!" Leng Xuan didn't allow Lin Tianyu to question it, and pulled him out of the pavilion, and Lin Tianyu picked up a cup of tea, so he had to put it down again.

"You're in such a hurry to do this, what's the use of doing this?"

"It's to verify the feasibility, if it succeeds, it's a good self-defense weapon, don't underestimate it, when you have that firearm, maybe even the gods will scare me." ”

"Hehe, it's that powerful?"

"Maybe there will be, just wait and see!"

"Alas, anyway, the novelties of the fifth brother are all things we can't think of! Okay, then learn "Divine Sword Roar" first, and if you learn it, I will help you go to Luoyang to purchase it immediately!"

They stood still, and Leng Xuan gave Lin Tianyu a pair of Jingfeng's double swords.

"This Jingfeng double sword is really a good sword, and it is also a couple's sword created by Guo Jing and Du Feng back then, but unfortunately this couple died of secular persecution, but now these two swords are still extremely sharp, alas, I don't know if Brother Guo and Brother Du are still safe under Jiuquan. Come, fifth brother, please. ”

"Oh, there is such a thing? There are also people in this world who are engaged in the foundation? It's really trendy. Leng Xuan seemed to suddenly understand the origin of the names of these swords, and muttered.

"Huh?"

"It's okay, second brother, please!"

Leng Xuan was not polite, and he practiced and taught Lin Tianyu's "Divine Sword Roar" magic skill swordsmanship with a swing of his sword! A child teaches a fairy magic skill, and it is estimated that it can only be found here.

On the third day, Lin Tianyu really came over with a few packages, this time he actually rode a new mount, this time it was not a bird, Leng Xuan also asked before he knew that it was a divine beast called chasing the wind, but unfortunately this divine beast was only temporarily borrowed by Lin Tianyu for convenience, not his own. But this way people will not say that he is flying slowly.

Leng Xuan hurriedly mixed some gunpowder according to the proportion of dispensing, filled a hemispherical iron shell, found two suitable pieces of fire stone separated by cotton paper and loaded into the iron shell, filled with gunpowder, and then the two iron shells were tightened, and a firearm was done in this way, because there was a fire stone in it, it was no longer lit with a fuse, as long as it was hit, the fire stone squeezed through the cotton paper in the middle, and it would explode if it rubbed out a little spark, Leng Xuan's design is for the convenience of use.

"Second brother, fairy, you retreat, how about I experiment with this fire thunder?"

Leng Xuan threw out hard, "Boom!!" A bang exploded, and a cloud of black smoke rose, it was really a thunder on the ground, deafening, and the eardrums of the people who exploded were buzzing.

"Wow!! Fifth Brother, is it so powerful? If you get close, it won't hurt people?" Lin Tianyu was obviously surprised, and Su Muyue covered her ears and hid in the pavilion.

"It's not just an explosion, it should be killed, this is still the smallest, if you pretend to be medium, you will definitely be able to kill people!"

"It's really amazing, no wonder you say that the gods and demons are scared of you, it's really amazing, you say, what is this thing called?"

"Hehe, it's called a grenade, it's okay to fire a thunder, there's no name, just call it!"

"Ha Luha, the second brother won't study any medicine in the future, the second brother will learn to make this with you, see who is not pleasing to the eye, and directly throw a few to kill whoever will be killed, which is much more convenient and more direct than using poison!"

"This is just the first sample, and it needs to be continuously improved, how thick is this iron shell appropriate? How can I charge more charges? It must be able to blow up others, but it is also safe enough when I carry it, otherwise it will not be good to blow up myself before I hurt others!"

"Only the fifth brother can come up with such a whimsical idea, it's so creative, the fifth brother taught me this principle, and I'll help you continue to improve!" Leng Xuan praised him for being too creative, and he didn't think it was ridiculous, this was just a very simple black powder he learned in high school, and the TNT shell explosives in the world over there were called powerful, not to mention the nuclear bomb hydrogen bomb. But this kind of thing is novel enough for Lin Tianyu, he is already a little fascinated and wants to learn from Leng Xuan!

"Okay, that's for you. It just so happens that I don't have time to study this when I practice every day, so my second brother will study more when he has time, but pay attention to his own safety, try more tests, and make grenades that are both easy to use and easy to carry, and give me some when the time comes, I can take self-defense, ha, ha!"

Leng Xuan told Lin Tianyu about the proportion of gunpowder, and said why he wanted such a ratio, how these three powders reacted, and why would they explode. In fact, Lin Tianyu only understood the proportion of the dispensing, and as for the principle of the explosion, he was really confused.

But the more foggy he was, the more fascinated Lin Tianyu seemed to be, Leng Xuan didn't expect that making this self-defense firearm would make Lin Tianyu so fascinated, he felt very surprised, Lin Tianyu didn't even ask to learn "Divine Sword Howling" this time, so he hurriedly went back to develop grenades.
