"What is the reason?"

"Impact, that is, impact, impact can cause gunpowder to explode, then there can be no other cause on the road that can cause gunpowder to explode, that is, impact."

Yan Yunzhou may still think this answer is fresh, but for Ning Qi, isn't it common sense that gunpowder is easy to explode when hit? Or why are dangerous goods called flammable and explosive, he raised his forehead slightly, this Qingyang Taoist will not be locked in the house for a few days and have nothing to do to hit his gunpowder, right? If you don't die, it's a big fate.

Yan Yunzhou went to the house and sat down, the door outside the courtyard had been closed, and Ning Ji looked at a few gunpowder pills on the side:

"You've been working on this for the past few days?"

"Ahh

Ning Ji put down the gunpowder in his hand, and Yan Yunzhou looked at the Qingyang Daoist:

"The things you make will explode even during normal transportation, how can they be used in the army?"

Isn't it possible to use it off-the-shelf? Let's not talk about whether it can be realized, but this is easy to explode when it is collided, it is simply a first-class dangerous goods, in case the soldier accidentally bumps it when he moves, then he will not send himself to see Hades first? He pressed his eyebrows:

Qingyang Daoist lifted the hair in front of his eyes, and looked like a scientific madman:

"As long as you find a problem, you can improve it, there must be a problem with the ratio of blending, I will try again, and I will definitely make safe gunpowder."

Ning Qi looked at Qingyang's persistent and determined eyes, and sincerely admired his spirit of being willing to show up for science, which is also in this era, if it is placed in modern times, it is impossible for Nobel to owe him a prize in applied chemistry.

Ning Ji looked at the things on the table, he knew the proportion of black powder, one sulfur, two nitrate and three charcoal, but he knew that he had never done real black powder.

Black powder can be regarded as almost the most primitive gunpowder, which means that no matter how well-made gunpowder is, there is no way to overcome the natural properties of bombs that are afraid of heat and impact.

However, in ancient China, black powder was widely used in the battlefield and in the opening of mountains and rivers, which shows that mature black powder can achieve normal storage and transportation safety.

And the black powder made by Qingyang exploded in the transportation path last time because of uneven roads, which shows that his results are obviously problematic.

Because he and Yan Yunzhou made it clear, Ning Zhi no longer avoided suspicion this time, and he sat directly in front of Qingyang's table:

"That's what you use, aren't you? What is the ratio? ”

Yan Yunzhou looked at him, and the Qingyang Daoist also came over, but this time he looked at Yan Yunzhou, this gunpowder is also the biggest secret in the army, everyone knows that there is such a thing, but if you really pick up how to do it, only Yan Yunzhou's most trusted person may know. 、

Yan Yunzhou spoke directly:

"Say."

Ning Ji looked at Qingyang and pointed to the three things on the table:

"Probably, this yellow one is the least, then this one, then carbon."

Ning Ji looked at the things he pointed to in order of sulfur, potassium nitrate and carbon, listening to his sentence, he probably understood that the Qingyang Daoist was actually experimented, only knowing which was the least, which was the most, and which was about the same amount, he sighed in his heart:

"That's how you made all that gunpowder in the past?"

I don't know why Qingyang Daoist seemed to hear a feeling of contempt and speechlessness in Ning Ji's words, and he didn't know how to describe it, but if Ning Ji was asked to describe it, it would probably be a feeling of being a scumbag suddenly being named and asked by a scholar.

"Ahh

Yan Yunzhou saw the somewhat speechless expression on Ning Qi's face and spoke:

"Any questions?"

Ning Ji took a deep breath and closed his eyes, problem, of course there is a problem, a chemical experiment, it is still such a violent chemical experiment, and the amount of each reactant needs to be strictly controlled.

And the so-called gunpowder made by Qingyang, I am afraid that it can only ensure that it can be fried, each reactant is about the same amount, together it is simply a car of flammable, explosive and inferior dangerous goods, and three cars were transported, these three cars did not all explode, but only exploded one car.

He took a deep look at Qingyang:

"You haven't been blown up yet, you're really a darling of heaven."

Qingyang Daoren... Ha?

When Fang just came in, even Zhou Wei was waiting outside, so there were actually only three people in this room now, Yan Yunzhou, Ning Ji and Qingyang, and Ning Qi was no longer clumsy:

"The ratio of these three things is one to two to three, you can weigh them with a scale, and the things that come out of this way are not so unstable."

Qingyang Daoren was shocked:

"How do you know?"

"I had a dream before, and an immortal master told me in the dream, but I haven't done this thing either, I just know such a ratio, as for whether it really depends on you to try."

Qingyang Daoist heard it all in the clouds:

"The immortal master gave you a dream? It shouldn't be, the immortal master should be entrusted to me even if he dreamed. ”

Yan Yunzhou coughed lightly:

"Since there is already a possible effective method, you can try it, remember to do it during the day in the future, and don't make such a big move at night."

Qingyang Daoist suddenly came to Ning is eyes:

"Did the immortal master say anything else? Did you ignite in your dreams? ”

Rather...

"No, that's all the immortals said."

Even if Ning Qi wanted to teach more, he wouldn't, he only knew a chemical equation for the black powder reaction, and it was naturally impossible for them to do this experiment in the laboratory when they were in school, that is to say, in addition to being able to tell Qingyang the master the exact proportion of reactants, he actually didn't know much more than him.

Qingyang Daoist couldn't wait to get this answer, Yan Yunzhou and Ning Ji went back to the room together, and Ning Ji was a little silent on the way back.

Because he knew that even with this ratio, the Qingyang Dao people made a mature black powder, but this still could not change the characteristics of the black powder itself that was afraid of heat and impact.

After going back, the two of them obviously lost their sleepiness, Yan Yunzhou tossed this time at night, and his face was not very good, so he poured him a cup of hot water:

"Drink some hot warmth and warmth, and ask if you want to ask."

"You also had gunpowder in your time?"

Ning Yi laughed one:

"Yes, the weapons of our time were already very advanced, and this thing made by the Qingyang Dao people was called black powder in our place, which was a famous invention in our ancient times.

But by our time, black powder had been replaced by something else, and when I was in school, I had learned how black powder reacted, that is, how it could explode, but I never tried it. ”

Yan Yunzhou nodded, with some emotion in his eyes, the era that Ning Ji said was indeed very subversive of his imagination.

Ning Qi hesitated a little, but finally spoke:

"The power of black powder is indeed great for people who only use cold weapons, but it is not too big, even if the Qingyang Dao people improve it according to my way, the bomb itself will still be afraid of heat and impact, it can only be said to be relatively stable."

Yan Yunzhou leaned back in the chair and rubbed his sour eyebrows:

"Can you guarantee normal storage and transportation?"

Rather blame is actually not too sure:

"To be honest, I haven't seen real black powder, but our ancient black powder will be used in war, so I think there should be no problem with normal storage, but there is definitely a risk of explosion."

After all, their descendants can only prove which dynasty the black powder once existed, and as for whether the army itself caused the explosion of the black powder, he has not seen the exact record, and he can't say nonsense.

Yan Yunzhou understood what he meant:

"I see, gunpowder is a deterrent, and this thing can't be relied on alone in this battle."

Ning Ji remembered something, but after all, he couldn't help but say nothing, Yan Yunzhou smiled:

"Okay, I'm tired of the day, let's sleep."

Ning Ji followed him to the bed and didn't say anything, but after lying down, something flashed through his mind just now.

That is TNT, that is, trinitrotoluene, and he obviously knows more about TNT than black powder, which was known as the explosive of the king of explosives in World War II.

He remembered that he had read an article about the large wooden handle grenades in Germany during World War II, which were filled with TNT, which was small in size and light in weight.

But the explosion is powerful, and it is not in the same order of magnitude as black powder, and the most important thing is that TNT can be regarded as a fairly safe explosive compared to black powder.

Because TNT is not sensitive to friction, vibration, and impact, even if it is shot, it will hardly explode, and there is no speed in this era that can compare with the speed of a bullet, which means that TNT in this era can be said to be absolutely safe from open flames.

If you want to apply explosives on the battlefield, in addition to being able to blow up, you should also consider storage and transportation, if these two things cannot be solved, then the application is a dead letter.

Trinitrotoluene, Ning Ji's mind began to synthesize its path, but after thinking about it halfway, he paused again, during World War II, the common appearance on the battlefield was still soil grenades, mines.

Although he did not study the weapons of that time in detail, he also knew that the earthen grenades and mines used in the country at that time had not completely departed from the reaction of black powder.

During the First Sino-Japanese Naval War, Japan added picric acid to black powder to greatly enhance the power of explosives, but it was originally derived from the black powder reaction.

And TNT was a luxury in World War II, stability, and power are superb, if this explosive is applied in the current era, it is almost a product of the times, subverting all existences, is it really right to create such a thing in this era?

Ning Ji thought about it for a long time this night, and didn't know when he fell asleep, so he went to the wounded barracks early the next morning, and let's see the progress of the Qingyang Dao people, let's get his hospital done first.

On this morning, Yan Yunzhou's letter to Song Chengyan, the general of Liangzhou, arrived with the arrows, and the veteran in the big tent held the letter, his face was a little unsightly:

"General, is this a letter from Prince Yan? What is it? Arrowhead? ”

The people in this big tent are all people that Song Chengyan trusts, and he handed over the arrow cluster:

"Look at it, this is the arrow used by the Qiang clan that appeared on the battlefield of Baicheng."

Seeing this different kind of arrow, the faces of the soldiers below were not good-looking, they naturally had noticed Ruoqiang's abnormal movements, Ruoqiang borrowed the Daoshan country and the northern herd, the Qian tribe had an affair, and at this moment the northern border was fighting, according to the usual time, they should have stopped Ruoqiang's movements.

When they got the news, Song Chengyan was already ready to play the troops, but he was stopped by a secret letter from the capital, and the treasure seal covered in the secret letter could not be faked.

But this secret letter did not let them face up to Ruoqiang who tried to collude with Beimu and the Qian people, but let them stand still, and if they saw it, they didn't see it.

Song Chengyan's face was extremely ugly, and Yan Yunzhou did not mean to ask the teacher in the whole letter, but instead opened his mouth to understand his difficulties:

"General Song saw the words like meeting, how did this letter come from to think that the general army was clear, the general guarded Liangzhou for many years, Jin Chu was deeply admired, I think no one can know more than the general about Ruoqiang's forging technology, this arrow cluster has recently appeared in the hands of the Qian, the general is difficult This king has also heard.

However, the northern border is unstable, and the turmoil in the Western Regions is not a trivial matter, and it may cause a catastrophe if it continues to sit idly by, and the king has to go to the court. ”

On the other hand, the adjutant general was also very uneasy when he saw this letter:

"General, this arrow cluster is made by Ruoqiang and can't run, this arrow cluster appeared on the northern battlefield, which has confirmed the fact that Ruoqiang colluded with Beimu and the Qian tribe.

If Prince Yan brought this matter to the court, it would definitely be our first to bear the brunt, and that day, the person who wore the secret letter passed the decree and destroyed the secret letter, and there was no proof of death at all, if it made a big fuss in the court, this..."

He didn't finish his words, but Song Chengyan didn't know what he meant, the people who came to deliver the decree that day not only had a secret letter covered with a treasure seal, but also a letter from their family members who were summoned to the capital.

They can not believe that there is no public will, but they always know the letters of their families, and this is a silent threat.

The situation between the emperor and Yan Yunzhou became more and more tense at this moment, and this letter clearly showed that the emperor did not hesitate to connive at Ruoqiang and the collusion between the Beimu and the Qian people in order to restrain Yan Yunzhou.

But this matter is impossible to put on the surface, so there is that secret letter and a handwritten letter from their family.

And now that Ruoqiang's weapons have appeared on the battlefield in the north, Yan Yunzhou will definitely not tolerate it, after he goes to the imperial court, with the knowledge of all the civil and military officials, it is impossible for the emperor or the Wei family to admit the fact of that secret letter.

When the time comes, it will only be them who will be responsible for directing the northern border into a crisis.

"General, what shall we do? It is impossible for the court to recognize the secret letter. ”
