Cutting over the end of the Ming Dynasty: a dog-leg knife at the beginning

Chapter 398 Good grades
Pang Chun, Pang Xia, and other technical madmen looked at Yang Menglong sympathetically, without any intention of laughing at him.It's sad enough that people spend so much money and end up with a bunch of useless things that can't explode at all, and it's not kind to laugh at them.Fortunately, even if the collodion is useless, the nitric acid production line will not be abandoned. Isn't it possible to make nitroglycerin and collodion?Pang Xia comforted Yang Menglong: "My lord, don't be sad, at most we won't make collodion in the future, we will directly make collodion..."

Yang Menglong's eyes rolled quickly: "Colloid?"

Pang Xia said: "That's right, we directly make gun cotton, which is much easier to detonate than this!"

Yang Menglong jumped up and shouted: "Go, get some gun cotton! I don't believe in this evil!"

Pang Xia asked: "What do you want to do?"

Yang Menglong pointed at the collodion, gritted his teeth and said, "I want to try to see if the collodion can detonate it, his grandma's!"

Soon, the gun cotton came.In the same old way, stuff the cotton into a thin copper tube and seal both ends, connect the fuse, then insert the copper tube into the collodion, ignite the fuse, and then everyone hides away... …

The flame quickly devoured the fuse, quickly approached the copper pipe, and finally disappeared at the mouth of the copper pipe.

Then----

boom! ! !
A ball of orange-red flames burst out, smoke billowed up, and the ground shook violently like an earthquake. Those guys who were hiding in the distance watching the excitement softened their feet and turned into rolling gourds, with ears like It was buzzing like being slapped severely!Many stones were thrown high and fell down like hailstones, whoever hit them was unlucky, but everyone didn't react to this, all of them turned pale, obviously frightened by the thunderous explosion !
Not only them, but everyone in the military factory was frightened, and they could be seen flying around hundreds of meters away!Don't blame them, most people have never heard such a terrifying loud noise in their lives, and it is normal to be scared out of their wits.In the midst of gunpowder smoke, Yang Menglong jumped three feet high, dancing with hands and feet, jumping and shouting like crazy: "I understand, I understand, hahaha, I finally understand!"

Pang Xia called: "My lord, what do you understand?"

Yang Menglong said: "Detonator! I forgot the detonator! Without the detonator, this thing can't be detonated at all!"

Everyone was astonished: "Detonator? What the hell?"

Yang Menglong beamed with joy: "The so-called detonator is just like the small tube I made by stuffing the collodion into the copper pipe just now! It will explode by itself, and the power is huge! The pressure and high temperature generated by the explosion of the detonator will detonate the collodion. Destroy everything... still don't understand? It is equivalent to two kicks, detonating the small ones, and the big ones will explode!"

Everyone still doesn't understand.

Yang Menglong was too lazy to explain, so he got a piece of collodion, connected it to the fuse, and lit the fire.

Everyone expressed calmness, standing next to the collodion, it will not explode anyway, what are you afraid of?
As expected, the fuse burned to the end and went out, and the collodion did not respond.

Yang Menglong made a detonator out of collodion, inserted it into the collodion, connected it with a fuse and lit it.This time, everyone scrambled away like a rabbit that had been shot.As expected, more than ten seconds later, there was an even more frightening loud noise that caused severe pain in everyone's eardrums, and the collodion turned into a big fireball, blasting stones into the air!

The guy who had tasted nitric acid with his face exclaimed excitedly: "I understand! You must add a mine... a detonator to successfully detonate the collodion!"

Yang Menglong nodded again and again: "Yes, yes, it wouldn't explode without this thing!"

Pang Chun and Pang Xia laughed: "That's easy, we just need to ask people to make more detonators!"

Yang Menglong shook his head: "It's not that simple! It's unrealistic to use cotton as a detonator. It's too dangerous. It may explode before the shells fly out of the barrel. We can't connect a shell to every shell." A long fuse, right?"

Pang Xia asked: "What should we do?"

Yang Menglong looked at an empty small copper tube in his hand and said: "The next thing you have to do is to find a way to come up with a detonator that is safer and more stable, but will explode if it is subject to a violent collision or an open flame. , this is very important, without it, no matter how much collodion we make, it will be in vain!”

Pang Xia's eyes widened: "How can this be done!"

Yang Menglong shrugged and said, "I don't know either, it's up to you...Come on, I'm optimistic about you!"

A group of dynamite madmen looked at each other and wanted to cry from the bottom of their hearts.

This is a typical case where the superior speaks loudly and the subordinate breaks his leg...

The earliest detonators used to detonate yellow explosives were made of mercury fulminate. This thing is a powerful and extremely sensitive flammable and explosive substance. It is perfect for using it as a detonator or fuse.But mercury fulminate is too sensitive. In a dry state, it is as dangerous as nitroglycerin. It may explode on its own if left unmoved. This shows how deceptive it is.The most terrible thing is that the sulfuric acid used to make mercury fulminate is very pure. If the purity is not enough, the resulting mercury fulminate is often a waste product and cannot be used.Of course, Yang Menglong didn't know these things. He was not an encyclopedia, so he had no choice but to let these guys explore slowly without rushing.

With the joy of solving a big problem, Yang Menglong returned to the arsenal humming a ditty. Xiao Yufang was startled when she saw his disheveled face: "How did you make it like this? You made the big explosion just now?"

Yang Menglong nodded happily: "Yes, I made it!"

Xiao Yufang slapped her heart: "How did you do it? You almost scared me to death just now! By the way, are you injured?"

Yang Menglong said: "I'm fine! It's almost enough to see here, let's go, let's go to another place to see!"

The trip to the military factory did not bring many surprises to Yang Menglong.The breech-loading smoothbore rifles and breech-loading smoothbore cannons he dreamed of still have no trace. Mortars... The leader of the scientific research team responsible for studying mortars has been clamoring to jump off the building several times. As for rocket launchers, it is even more so. Needless to say, all the members of the team were in a daze looking at a lot of steel frames, iron pipes and other messy things.Fortunately, the application of machine tools in military factories has become more and more common, which has greatly improved production efficiency. The measurement units such as millimeters, centimeters, decimeters, and meters that he has spared no effort to promote in the past three years have also successfully replaced feet, feet, and meters. Fuzzy units such as feet and inches, and more precise measurement tools such as calipers and tape measures have also begun to be widely used. The rulers and rulers in the hands of craftsmen are also engraved with Arabic numerals, accurate to the millimeter. The precision of machine tool molds The level is improving little by little.This little bit of improvement seems very inconspicuous, and it does not seem to bring additional income. On the contrary, more money will be invested, but isn't technological innovation accumulated from this little bit of progress?

Of course, the most gratifying thing is that this bastard finally lowered his standards, and decided to produce breech-loading smoothbore guns and breech-loading smoothbore guns that are relatively less technically difficult, and then go for rifled guns. The technicians who have been driven crazy can finally breathe a sigh of relief.In fact, in this era, even if the breech-loading smoothbore gun and the breech-loading smoothbore gun do not have the advantages of range and accuracy, they can still hang the front-loading smoothbore gun. The advantage in the rate of fire is there!
The next place Yang Menglong ran to was the Institute of Agricultural Sciences.There are more than [-] great people who have studied farming technology here. The old man Mai Fengshou who is self-taught and can prepare pesticides to kill insects is the team leader. He is responsible for studying how to improve seeds and how to kill them. Insects, disease control.These old people who have been dealing with crops all their lives have contributed a lot of useful experience. For example, mixing wheat with castor oil, spirits, and even tobacco water before sowing will greatly enhance disease resistance; another example Grind the fruit or root of the Son of Heaven into powder and mix it with water and spray it on the crops, which can kill a large number of pests and so on.Now they have built a greenhouse, and in the mid-winter season, they also grow juicy greens, bright red tomatoes and even thick and long cucumbers. In the eyes of Wuyang people, these are all gathered together without doing business all day long. The old man who messed with some messy things is simply a god!
When Yang Menglong and Xiao Yufang arrived, those old men ran to the greenhouse to look at their treasures. Yang Menglong only saw the workers in the factory under the Agricultural Science Institute driving donkeys to scoop up a large number of Tianzi fruits. Grind it into a powder, and some jobs chop up the sun-dried poison ivy, ready to be rolled into a powder with a roller.Both rotenone and poison roten contain highly toxic rotenone, which are ideal pesticides. Yang Menglong followed the advice of these old farmers and allocated a sum of money to buy large quantities of rotenone and poison vine, process them into powder, and then use them in his own fields Tried it, good guy, after spraying it, the pests were dead the next day!Having tasted the sweetness, Yang Menglong immediately got excited and built the most primitive pesticide processing factory. Now this factory is stepping up production in order to provide enough pesticides for Heluo Town next spring... As soon as the weather turns warm, the pests will come There are so many crazy things, without pesticides, you just wait to cry and pass out in the toilet.Wuyangwei's Juntian can get such a good harvest this year, at least half of the credit is due to these pesticides.

The advantage of this kind of pesticide is that it is pure natural, there will be no pesticide residues, and you can eat it with confidence after the expiration date... Well, even if there are pesticide residues, people nowadays don't care.In order to survive, even the Avalokitesvara soil can be eaten as usual, and still afraid of this little pesticide residue?

Yang Menglong took a serious look at the stock of pesticides, and after learning that the stock of pesticides was enough to meet the needs of the entire Heluo Town next spring, he returned home very satisfied... The results are good, and a bumper harvest next year can be expected again!
Riding on horseback, Xiao Yufang frequently looked back at the pesticide processing factory with a thoughtful smile on her lips.She really can't understand Yang Menglong, he spends money lavishly, spends every penny he has, and spends it on unnecessary places, but now it seems that he has spent every penny On the edge of the knife, in exchange for generous rewards.

"The pests in September were very serious, and a large area of ​​vegetable fields was gnawed bare by them. Master Mai asked everyone to spray the medicine he prepared. Everyone did it with a tentative attitude of trust. Unexpectedly, early the next morning, those The insects died all over the ground." Xiao Yufang said softly, "You have done another great thing. With these medicines, everyone no longer needs to be afraid of pests."

Yang Menglong shook his head and said triumphantly, "Worship me? I'm very, very discerning!"

Xiao Yufang said: "That's right, if you don't have vision, how can you manage the current situation? By the way, you have seen the factory, where do you want to go next?"

Yang Menglong said: "Go to Fucheng. Master Fang asked me to go to Fucheng to celebrate the New Year, and said that he had something important to discuss with me. It just so happens that I plan to hold a sports meeting in Fucheng, so I'll drop by!"
