Instead of answering him, Ning Ji asked a question that had nothing to do with the topic at all:

"Isn't the pressure of fighting against the imperial court much greater than against the Qiang?"

Yan Yunzhou was stunned for a moment, as if he didn't expect him to ask:

"Be honest with me."

"Yes, although the Qi people are brave and good at fighting, but the number is not much, besides, we are guarding the moat, it is always better, although the imperial court has been slacking off in these years, but there are still a few veterans who fought with the first emperor, although Li Qi is not a Ming monarch these years, but his throne is inherited from the first emperor, and the name is justified.

Although many of these veterans are old, the imperial court still has an absolute advantage in numbers, and besides, the imperial court has much more food and grass than us, and it is indeed not beneficial for us to have a long-term confrontation. ”

Ning Qi listened to what he said, and remembered Zhu Di's Battle of Jingjing, too, eloquent and strategic, experienced in a hundred battles like Zhu Di, the king of Yan, the Battle of Jingjing has been fought for four years, even if the army of tigers and wolves in Yan Yunzhou's hands can be compared to Zhu Di's army, but after all, it is against the entire imperial court, and they are not considered to have an advantage.

But can Yan Yunzhou's body really withstand such a long war? The idea of suppressing TNT that night began to spark again.

Yan Yunzhou looked at him as if he was a little distracted, thinking that he was too worried, raised his hand to pour him a cup of hot tea, and comforted him softly:

"Drink some tea, you don't have to worry too much, although the number of generals in the imperial court has an advantage, but over the years, these troops have eaten empty salaries and neglected to train soldiers, and they have long lost the majesty of the first emperor, those veterans are old, and I have studied their tactics, and it is not without a chance of winning."

Ning Ji raised his hand and drank the tea in the cup, listening to Yan Yunzhou's words, he also knew that there was a chance of winning, but I am afraid it was also a miserable victory.

He closed his eyes for a moment, he didn't know if it was right to bring a weapon that didn't belong to this era here, after a moment of struggle, he opened his eyes, his eyes were clear, and he looked at the person in front of him:

"There's one thing I want to tell you."

Thinking about what Ning Qi said last time, Yan Yunzhou was extremely sensitive to this, and immediately asked almost reflexively:

"What's the matter?"

"The gunpowder made by Qingyang Dao people has insurmountable shortcomings, so they are afraid of impact and high temperature, even if they are mixed according to the ratio I gave him, this shortcoming will not be overcome, but it will be much safer and more stable than the ones he made before, and it can also be used on the battlefield.

However, I went to the bottom of the city tower yesterday to see the injured corpses, and found that the power of firearms is actually limited, many people were not actually killed by gunpowder, but were injured by the gas wave generated by the explosion of gunpowder, and more people were actually injured by swords, you actually know this, right? ”

Yan Yunzhou didn't expect that Ning Qi would see so many things just by going to the city downstairs yesterday, his expression couldn't hide his amazement and appreciation, but he said very calmly:

"I really can't hide anything from you, yes, the power of gunpowder is indeed not as miraculous as it is rumored, but because there is no gunpowder in the hands of the enemy, gunpowder is relatively rare on the battlefield, and it is powerful.

Therefore, many people have a natural fear of gunpowder in their hearts, so that as long as gunpowder appears, the enemy will be in chaos, so that they will return defeated. ”

Ning Ji saw that he didn't deny that he knew that he had already counted it in his heart, but he still said worriedly:

"But fighting with the imperial court is not like fighting with Beimu, it is likely that it will not succeed in a short period of time, once the other party realizes the fatal shortcoming of gunpowder, then their numerical advantage will be reflected."

The analytical ability of the widow king, who is very knowledgeable all the way, is not covered, even if he does not know how to fight, but he also understands that there are only more than 100,000 soldiers and horses in the north.

But the Great Liang army is by no means the only one, even if it is some ordinary troops who have not received too strong training, but the number is also real, even if the other party uses the attrition method, it is enough for them to choke.

Yan Yunzhou took a deep breath:

"Then don't let them find out that the power of gunpowder is indeed not as great as it is transmitted, but it is still powerful compared to them, as long as it is used properly, it is enough."

Yan Yunzhou has fought countless battles, and he has long understood how to use his strengths and weaknesses, and Ning Yi also understands his thoughts, but if you want the imperial court not to discover the weakness of gunpowder, then you must reduce the number of times gunpowder appears on the battlefield, which is actually a weakening of themselves.

Ning Qi suddenly spoke as if he had made up his mind:

"I can make a kind of gunpowder that is much safer than the current black powder, called TNT, this gunpowder is not afraid of impact, whether it is stored or transported, it is much safer than the current gunpowder, but the power of this gunpowder is much greater than the gunpowder made now.

It was an accident that I came to your time, but is it really right to make a very dangerous gunpowder that does not belong to this era? ”

Ning Qi's eyes inevitably brought a heavy struggle, every era has its own development trajectory, this trajectory has its own unique laws, anything beyond the existing level of production, it is very likely to break the balance of this trajectory.

Just like the invasion of alien species, it will have an extremely bad impact on the existing ecological environment, Ning Ji knows that he can't do it willfully, but he can't help but wonder in the past two days, whether it will be inevitable for him to come to this era, and there are always more or less coincidences in every era to move forward.

Just like the Ming Dynasty opened the vigorous Age of Discovery, in fact, it was just because Zhu Di wanted to find the missing Emperor Jianwen, this is not a coincidence, and is it possible that he is the coincidence and opportunity to take a step forward in this era?

A question was placed in front of the two people at the same time, Yan Yunzhou knew the truth of the guilt, and he understood the importance of a killing weapon for the ruler's ambition, and he understood Ning's struggle:

"This thing is powerful?"

Ning Yi nodded:

"Although this gunpowder is nothing in my time, the power of this gunpowder is not small, at least in my era on the battlefield a few decades ago, it is called the king of explosives, of course I can't make such a professional thing.

But compared to the current gunpowder, the power must be much greater, in fact, I thought of this gunpowder when I went to Qingyang's house that day, but I have been hesitating for the past few days. ”

Yan Yunzhou understood, he was also a little pensive, and spoke for a while:

"The danger of a weapon is not in the weapon itself, but in the person holding the weapon, the advent of such a weapon will inevitably lead to a scramble from all sides, the reason is very simple, no one wants to be a fish on the board, the husband is not guilty, Yu'an, don't do it, without it, I can also fight the world."

Now the people in the palace just knew that Tianling Zhenren had taken down the entire Yuqingguan when he made gunpowder, and if Ning Zhen would make this gunpowder way to spread it, then he didn't know how many people would become the target of scramble or assassination, and even he had a selfish intention.

He still remembered that he had told him the oath he had made: "I am determined to do my best to eradicate the sickness of mankind, to help the perfection of health, to preserve the holiness and honor of medicine, to save the dead and the wounded, and to spare no hardship." ”

Although he had only heard it once, Yan Yunzhou knew that this oath had been deeply rooted in Ning Yao's bones, and Ning Qi's hands should be for curing diseases and saving people, saving lives and helping the wounded, and should not be contaminated with the endless sea of blood.

How could he not see it, he would rather die and worry about him, so he struggled in his heart, but he still told him that he could make gunpowder, but how could he be willing to let those holy hands stained with blood.

Yan Yunzhou's attitude was indeed something that Ning Ji didn't expect, he blinked his eyes and didn't even know what to say for a moment, and only spoke for a long time:

"Is it really not needed?"

Yan Yunzhou shook his head slightly, and his hand shook Ning Yao's hand:

"There is really no need, our Director Ning is from Pudu sentient beings, and the matter of the war will be left to me, rest assured, I will take care of my body."

This matter was suppressed like this, and in the afternoon Yan Yunzhou went to the front hall as usual, but Ning Yi did not go to the wounded barracks, he sat alone at the table and looked at his hands, Yan Yunzhou's intentions he understood.

He didn't want him to get into a whirlpool of danger, and he didn't want to get blood on his hands, he knew that, but was it really right not to do it now?

Ning Qi thought about the current situation from beginning to end, in terms of circumstances, Yan Yunzhou's and Li Qi must only have one, there is no doubt that he will definitely choose Yan Yunzhou, he believes in Yan Yunzhou's military ability, but he is only afraid that his body will not be able to withstand the hardship, moreover.

As far as the world is concerned, although he has only seen Li Yan a few times, but the style of Youzhou is there, a county king who holds an abacus all day long, puts the money and grain of the entire Youzhou in his head, and cultivates fertile land so that the people of Youzhou who are poor can live a worry-free life is always better than the one on the throne now.

It is reasonable to be reasonable, this Liang Jiangshan is a fortunate thing, although the people are bitter in the war, but it is better to suffer at this time than to decay in the hands of Li Qi from then on, an emperor who can collude with foreign tribes, he does not want to think about the lower limit, so this war must be won.

Ning Yi directly pulled out a piece of paper, TNT he can indeed stop doing it now, but he can do it at any time if he wants to, or he has to straighten out the reaction process first, otherwise it will be in vain.

In fact, there is only one step in the synthesis of TNT, that is, toluene and nitric acid directly replace the reaction under the catalytic and heating conditions of concentrated sulfuric acid, and nitro replaces the hydrogen on both sides and opposite of the toluene methyl group, and trinitrotoluene, that is, TNT, can be directly obtained.

A line of chemical formula appeared on the paper in front of Ning Qi's eyes, a very classic substitution reaction, to be honest, this reaction is very simple, completed in one step, just like the reaction of preparing acetylsalicylic acid, that is, aspirin, can be obtained in one step, which seems to be very humane.

However, the problem of baldness comes again, toluene, toluene, how is he going to synthesize toluene... Ning Qi closed his eyes for a moment, vigorously recalled the chemical formula he had learned before, and finally thought of the most classic path.

That is the Friedel-Crafts alkylation reaction, benzene can be prepared, so benzene can be used to react with halogenated hydrocarbons under the catalysis of alumina, and this method can hang almost any carbon chain on the benzene ring.

And he doesn't need a complex carbon chain, he only needs to hang a carbon, that is to say, let benzene react with chloromethane, and then benzene can be directly turned into toluene.

The pen in Ning's hand circled two chemical formulas, alumina and methylene chloride, and he sat in his chair and thought about them for two quarters of an hour, not deciding how to get them.

The hair was once again caught into a chicken nest, and the pen was once again gnawed without being spared, for the first time, he felt that he and Yan Yunzhou's was too early, and asked people if he needed to make the explosives that were so awesome that they were hanging to the sky, and they didn't use it, if they used it, he wouldn't slap his face?

Chapter 84: The TNT Method (The Queen Mother's Exit)

When Yan Yunzhou came back in the evening, he saw that the back of a pen he usually used was bitten by Ning Jiao, he looked at the pages on the table that he couldn't understand, and when he was looking at it, Ning Qi came back from the wounded barracks.

"Yu'an, what are you writing about?"

In fact, Yan Yunzhou had some guesses in his heart, but Ning Zhi was not prepared to hide it from him:

"It's the way to synthesize that gunpowder, and I think it's okay if the war goes well in the future, and if it's really necessary, it's better to do something.

Who knew that I and yours were already blowing about it, and there were two things he didn't know how to do, okay, okay, don't worry about this. ”

Saying that, he pulled back the pages directly from Yan Yunzhou's hand, Yan Yunzhou knew that Ning should be measured, and couldn't help but pick up the pen that was bitten by him from the table and quipped:

"Well, I don't worry about it, it's just that you have to write something a lot."

Ning Ji saw an emboss on the pen that looked quite expensive, was silent for a moment, and then played tricks:

"You're a prince, didn't you just bite your pen? Stingy. ”

Yan Yunzhou watched him hit him upside down, smiling silently.

Ning Qi had some obsessive-compulsive disorder, the more he couldn't think about it, the more he thought about it, and at night Yan Yunzhou was all freshened up and ready to lie down, and he was still sitting at the table racking his brains and thinking.

Yan Yunzhou saw that he had eaten a little less than usual for dinner, asked him to prepare some food, got up and put it beside him:

"Come over and eat something, this thing is not in a hurry, I haven't eaten much for dinner, there are many wounded soldiers these days, you haven't rested well, come."

Ning Ji knocked his head while biting the cake:

"Hey, why did I forget the equation for lab-made methane? Shouldn't it? I can't remember it. ”

Yan Yunzhou clasped his wrist:

"Stop fighting, I can't remember if I'm stupid."

Ning Jiao was dragged to bed by Yan Yunzhou to sleep that night, Yan Yunzhou is a martial arts practitioner after all, even if his health has been bad these days, but that strength Ning Jiao can't break free.

For the first time, Ning Qi felt that the person was dragging himself like a chick, and suddenly his face was a little unbearable:

"You're still a sick person, why do you have so much strength?"

Yan Yunzhou pinched Ning Qi's wrist bone with his hand, his eyebrows and eyes were slightly raised, and the corners of his lips smiled:

"The emaciated camel is bigger than the horse, and if I can't pull you, I'm not far from dying of illness."

Ning Qi's face was black, and he didn't expect that there was such a sentence in this era, so he pulled out his wrist at once:

"Can't you talk about something auspicious?"

Ning Qi suddenly seemed to remember something, and sat a little closer to Yan Yunzhou:

"Hey, how did you learn martial arts since you were a child? Do you know how to do that? Is it the kind that can fly? ”

He has watched a lot of martial arts dramas since he was a child, and he has wanted to ask this question for a long time, but it must have been difficult to open his mouth before, but now that he has confessed his origin to this person, there is no pressure to ask.

Yan Yunzhou looked at his curious look and smiled:

"Some children of the family practiced swordsmanship when they were young, and after the founding of the Great Liang Dynasty, kendo has always been respected as the authentic martial arts, but our Yan family has guarded the northern border for generations, and the short weapons on the battlefield have suffered, so when I was young, after learning swordsmanship, I spent more time on the marksmanship passed down by scholars.

Can fly? Who are you listening to? People who practice martial arts are indeed light, and it is okay to leap with strength, but it is indeed an exaggeration to say that they can fly. ”

Ning Yi came to him and lay down, and gave Yan Yunzhou a series of martial arts films that he watched when he was a child, including but not limited to "Dragon Babu", "Heaven and Dragon Slayer", "Water Moon Cave Sky", "Xiao Shiyi Lang", yes, he has watched so many martial arts movies.

Yan Yunzhou listened to Ning Ji talk about something called TV, which could be used in various TV dramas, and felt like listening to the storyteller in the teahouse tell those bizarre stories.

Ning Qi spoke energetically, Yan Yunzhou also listened with great interest, and the two of them lay on the bed, chatting face to face:

"So, do you really don't have such martial arts here?"

Yan Yunzhou raised his hand and nodded on Ning Qi's forehead:
