"Congratulations on obtaining the "Steps for Preparing Nitroglycerine"...."

"What is this!"

Hearing the voice next to his ears, Li Ming was speechless and was about to throw the book aside again.

But in the middle of the movement, he suddenly stopped.

"Nitro, nitroglycerin!"

Looking at the words on the book, his mouth opened involuntarily.

At this moment, his pupils were widened and his hands were trembling.

Even to make sure that he was not dazzled, he rubbed his eyes repeatedly, and finally the text above still showed "Steps for Preparing Nitroglycerine".

"Fuck!"

Finally I couldn't bear it any longer, and a curse word came out instantly.

The whole person almost jumped up.

Nitroglycerin, this is nitroglycerin.

This is the most commonly used drug to treat angina pectoris and was invented by Nobel.

And this man invented nitroglycerin not to treat diseases, but as an explosive! It is a very strong explosive that was widely used during World War I and World War II.

Compared with black powder, which has limited power, nitroglycerine is far more powerful.

In the future, black gunpowder will not be considered an "explosive" in the classification of modern industry because of its relatively small power. At most, it will be regarded as a flammable and explosive substance. However, the power of yellow gunpowder is extraordinary.

And if he could perfect it, nitroglycerin would be much more stable than black powder.

And explosives are completely enough to enhance the national power of the Tang Dynasty.

Thinking of this, his eyes started to light up.

Then I quickly opened the book.

The steps for preparing nitroglycerin are not complicated, and there is not much content either.

Li Ming finished reading it after just a moment.

After reading it, he couldn't help but feel even more happy.

Because this so-called "Steps for Preparing Nitroglycerin" turned out to be the steps for preparing diatomaceous earth explosive developed by Nobel.

It contains extremely detailed content.

There are also extremely detailed steps.

"Come here!"

Suppressing his heart, Li Ming shouted directly outside.

Soon, a maid ran in quickly.

"Your Highness!"

The maid spoke with respect and caution.

There is no way, in the past few days, there have been rumors circulating in the palace that His Highness King Cao is not thinking normally.

"Buy some saltpeter, white ash, lard, and sugar cane for me!"

"By the way, there are these!"

After speaking, Li Ming quickly read through all the items needed to make nitroglycerine.

But after he finished reading, he found that the little maid was still cute.

He couldn't help but frown.

"Why, can't I buy these?"

Words speak.

And his voice instantly made the maid react.

"Yes, it's okay. Your Highness, please wait a moment. I'll buy it for you right away!"

Li Ming spoke again, causing the maid to react and answer quickly.

And when he heard the maid's response, he couldn't help but breathe a sigh of relief. At this time, he couldn't help but look at the book in front of him happily.

This so-called "Steps for Preparing Nitroglycerine" can be more accurately said to be the preparation of nitroglycerin by local methods.

Because of this, even more than a thousand years ago, he still had a way to prepare nitroglycerin.

And once he could successfully make it, his eyes couldn't help but light up.

This is yellow gunpowder, which is a higher level than black gunpowder. If black gunpowder still has problems here and there, then most of the problems with yellow gunpowder can be said to have been solved.

Over the past thousand years, once this yellow gunpowder appeared, it would be enough to directly elevate the military strength of the entire Tang Dynasty to a higher level.

It is actually very difficult to make an explosive package with black powder. After all, black powder needs to be large enough and adaptable to the environment to produce a huge explosion. However, yellow gunpowder does not have such a big problem.

When the time comes, a person from the Tang Dynasty will be able to blow up the surrounding enemies with just one explosive pack.

Are you still afraid that the national strength cannot be improved?

Thinking of this, he couldn't help but feel extremely hopeful.

And soon, the maid bought him what he needed.

At the same time, he has also dug several large holes in his small courtyard.

Be prepared to use it to save your life if things go wrong.

After everything was completed, he began to order everyone not to approach or disturb him.

He just started to get busy.

The preparation of nitroglycerin is not complicated.

Treat glycerol with nitric acid and sulfuric acid to obtain a liquid, which is nitroglycerin.

This is even more true now that complete information is available.

The only problem is the diatomaceous earth explosive.

This thing can really kill people if it is not handled properly. If Li Ming remembers well, Nobel, who invented yellow dynamite, had his brother killed by nitroglycerin.

Although there are complete steps, in theory there will be no problems.

But you still have to be fully prepared.

In the small courtyard, Li Ming began to tinker quickly.

As for everyone in the palace, there is a high probability that His Highness King Cao has gone crazy again.

"Your Highness, what is this?"

A maid spoke carefully and glanced into the small courtyard.

"I don't know. His Highness asked people to buy some things this time, and then dug some holes in the courtyard. I don't know what to do? He didn't let anyone in."

The other maid spoke equally carefully.

Everyone can't help but feel at a loss as His Highness has been so nervous these past few days.

Next to dozens of maids, an old eunuch couldn't help but look worried.

As the eunuch arranged to serve King Cao, Zhao Jing felt that his future was gloomy.

Although it was assigned to the feudal lord, it was indeed a very tragic ending.

But he never thought that he would be so miserable.

When you meet a master, you still have an abnormal brain.

I looked inside the small courtyard again.

Zhao Jing gritted his teeth and made a decision.

"You are here to watch His Highness."

"I'm afraid I have to report this matter to His Majesty."

He spoke and gave instructions to several people.

"Yes!"

"Yes!"

Several maids opened their mouths, wanting to say something, but in the end they nodded and responded.

Even if they report it, they might be punished.

But His Royal Highness King Cao is obviously not normal. If he keeps hiding it, they will not be able to bear if something really happens.

And after giving instructions.

Zhao Jing quickly headed towards the palace.

But in the small courtyard, Li Ming didn't know that his maids and eunuchs thought he was insane, and he had to report the situation to his cheap father.

Now, after he had been busy for more than an hour, a small ball of liquid appeared in front of his eyes.

"Hoo!"

"Success!"

Looking at this mass of liquid, his expression was tense, but the corners of his mouth couldn't help but curve.

The appearance of liquid also means that nitroglycerin has been successfully prepared.

Next, just mixing the explosives is enough.

And this is undoubtedly simpler.
Chapter completed!
