"There are two versions of yellow gunpowder, 40% nitroglycerin and 60% nitroglycerin."

"Nitroglycerine, and this, this, yes, and calcium carbonate!"

"Let's get version 1 first!"

He spoke in a self-talking voice. He had already clearly remembered the contents of the book. As for the choice, he directly chose the first version.

There is no way, it is still a bit troublesome to prepare nitroglycerine by local methods, so you still have to use it sparingly.

The figure took action quickly.

Nitroglycerine has been successfully produced.

As for saltpeter and wood powder, these are readily available.

Saltpeter appeared in China a long time ago.

The only problem is calcium carbonate, but this problem is not big.

Less than half an hour.

Li Ming has already extracted a lot of calcium carbonate.

It’s just Li Ming tinkering.

The other side.

Zhao Jing has already hurriedly ran into the palace.

Reported the matter to the eunuch in charge.

The chief eunuch, faced with such an unbelievable thing, did not dare to show any signs of neglect and quickly reported it to Li Shimin.

In the bedroom.

Li Shimin and Li Ming, the cheap dad, are still busy.

On the ninth day of August in the ninth year of Takeori, Li Yuan passed the throne to him, and he ascended the throne in the Xiande Hall of the East Palace.

It wasn't until he actually took over the country that Li Shimin discovered to what extent the entire Tang Dynasty had declined.

There was a melee at the end of the Sui Dynasty, and the population of the entire Tang Dynasty was almost wiped out. At the peak of the Sui Dynasty, the population was 60 million. Today, the population is within the scope of statistics, only more than 10 million, or just over 200 households.

It’s not even just a matter of population.

The entire Tang Dynasty was in dire straits waiting to be revitalized.

In the imperial court and the Tang Dynasty, because he killed his brother and forced his father, there was always opposition.

Above the border, the Turks are even more ready to move, and it seems that they may launch a southward invasion at any time.

"I hope you can give me some time!"

Li Shimin murmured to himself, looking a little tired.

Now he can only hope that Turks can give him some time.

As long as he has time, he believes that he can quickly bring Datang out of adversity.

"Your Majesty!"

"Prince Cao's Mansion has important things to report."

While he was thinking, the voice of his personal eunuch Wang De sounded outside the door.

"Prince Cao's Mansion, Fourteenth?"

Li Shimin was stunned for a moment, and then thought of Li Ming, his fourteenth son who had just been canonized by him this year.

Then I couldn't help but have some doubts.

King Cao is different from his other sons in that he has never attracted much attention.

Why is there something important today?

But despite his doubts, Li Shimin still let the personal eunuch come in.

Soon Zhao Jing was led in.

"King Cao, what's wrong?"

Li Shimin asked Zhao Jing casually.

Zhao Jing snapped and quickly knelt down.

"Your Majesty, His Royal Highness King Cao, a few days ago, for some unknown reason, he suddenly suffered from epilepsy. His speech was strange and his behavior was strange."

"Today, I locked myself in the small courtyard again. I dug a hole in the courtyard and no one was allowed to enter."

.....

Zhao Jing was sweating profusely and without any hesitation in his words, he explained Li Ming's abnormal behavior in the past few days one by one.

Li Shimin couldn't help but frown at this statement.

"Are you saying that King Cao locked himself in a small courtyard today, dug holes, and behaved strangely?"

Li Shimin's frown deepened and he looked at Zhao Jing intently.

"Yes!"

"Yes, Your Majesty!"

Zhao Jing trembled even more and stuttered a little, but he still hurriedly answered.

"Okay, I understand, go down!"

Li Shimin waved his hand, and the beneficiary Zhao Jing went down.

It wasn't until Zhao Jing retreated that Li Shimin looked at the personal eunuch next to him.

"Wang De, why don't you go over and see what happened to King Cao?"

Li Shimin spoke.

Just when Wang De was about to respond.

Li Shimin immediately shook his head.

"Forget it, I'll go over and take a look in person!"

"I just happened to be a little bored. Let's go for a walk!"

When he spoke, Wang De's original words were no longer continued.

"Yes, Your Majesty!"

Wang De responded.

Then he quickly arranged the instructions for Li Shimin to leave the palace.

At this time, Li Shimin didn't know why, but he suddenly had a whim.

An hour later.

Ready.

Li Shimin took Wang De and several guards and stepped out of the palace.

As for safety issues, with Qin Qiong and Yuchi Gong beside him, I'm afraid no one in this world can hurt him.

Under the setting sun, Li Shimin felt inexplicably relieved as he walked into the dusk.

After wandering around for a while, he headed towards Prince Cao's Mansion.

When Li Shimin arrived.

Everyone in Prince Cao's Mansion couldn't help but be shocked.

Hurry up and go out to greet you.

At the same time, a loud voice also came into the small courtyard.

"Your Majesty has arrived!"

The eunuch's voice was sharp and could travel far.

In the small courtyard.

Li Ming, who was concentrating on preparing explosives, was frightened by the sound.

The liquid in my hand accidentally dripped instantly.

"Not good!"

His expression couldn't help but change.

The next moment, without any hesitation, he immediately jumped towards the pit next to him.

And that was the moment he fell.

The nitroglycerin on the test bench quickly produced a violent reaction.
