Soon in the small courtyard.

The explosives have been installed.

"Boom!"

The loud noise instantly spread throughout the courtyard, and the violent vibrations made everyone shake.

For better results, the ratio this time is much higher than last time.

The vibration this time will be more severe.

So much so that this moment is really like an earth dragon turning over.

If the palace was not large enough, the people around it might have been alarmed.

In the palace, many slaves and guards were a little unsteady.

And when everyone walked into the small courtyard again.

Only then did I realize that the courtyard had completely changed at this time.

In the middle, a huge pit six to seven meters wide and three to four meters deep appeared.

In the small courtyard, the flowers, trees, and rockeries that were not torn to pieces last time were almost all broken into pieces at this moment.

And because Li Ming added some iron pieces this time, pieces of iron pieces were forcibly embedded around the entire wall, causing the wall to suffer severe damage.

"This, this!"

Looking at this scene, even Li Shimin, who has been fighting for many years, cannot calm down.

As for Qin Qiong and Yu Chigong, they felt their pupils shrink, and their two copper-bell-sized eyes kept turning back and forth in the small courtyard and Li Ming.

Suddenly.

Li Shimin reacted instantly.

He quickly spoke to Wang De next to him.

"Wang De, no, Shu Bao, you go in person and pass on my order immediately to the Northern Army and mobilize troops. Jingde, you go out immediately and blockade Prince Cao's mansion. Without my order, no one can enter or leave. Anyone who violates will be killed without mercy."

!"

The words are solemn.

My breathing became heavier at this moment.

As an emperor on horseback, Li Shimin felt the huge effect of this thing almost instantly.

"Yes!"

Qin Qiong nodded. He also knew the seriousness of the matter and responded quickly.

"Uncle Bao!"

"Jingde!"

And listening to his father's words, Li Ming couldn't help but be stunned for a moment. At this time, he finally understood who the two black tower men were. They turned out to be Qin Shubao and Yuchi Gong.

While he was stunned, Qin Qiong and Yuchi Gong had already rushed away.

"Well, Father, it's actually not necessary!"

Watching the two people leave, and remembering Li Shimin's previous words, he couldn't help but smile.

"Fourteen, you may not understand. This thing is too important to Datang. We must ensure that it will not be leaked!"

Looking at Li Ming, Li Shimin's expression softened, and he no longer even called him King Cao, but Fourteen.

"Father, they actually don't know how to configure it. Although I asked them to buy the materials, it is impossible for them to make it with these materials."

Listening to Li Shimin's words, Li Ming couldn't help but breathe a sigh of relief.

The words are spoken quickly.

He didn't want to fail to make it clear.

Everyone in Prince Cao’s Mansion was immediately shocked.

In this feudal society, let alone impossible.

In order to keep the secret, it is nothing to kill some palace guards and slaves.

And listening to Li Ming's words, Li Shimin couldn't help but be startled.

"This is true!"

I couldn’t help but speak.

"Father, just look at this and you will know!"

Li Ming nodded, and then took out the nitroglycerine preparation book.

Li Shimin took it with doubts.

Then I opened the book.

The steps for preparing nitroglycerin explosives in books can be said to be extremely detailed.

Even described in a way that ordinary people can understand.

Even Li Shimin quickly understood the basics of how to make this thing.

Looking away, Li Shimin took a deep look at his son, and then nodded.

"I know!"

"However, there is still something wrong with you, Fourteen."

"Let's do this, these people will be temporarily transferred back to the palace, and I will send additional people to you!"

As he started to speak, Li Shimin seemed to be about to speak again, but Li Shimin waved his hand to stop him, and then continued to speak.

"Don't worry, I won't do anything to them, but they still don't want to leave the palace for the time being."

"Also, Fourteen, next time, don't leave this kind of thing on paper."

Li Shimin finished speaking.

After listening to the cheap daddy's words, Li Ming sighed and stopped talking.

This is most likely the best ending, at least Li Shimin didn't ask him where he got the things.

As for Li Shimin thinking that this thing was written by him, Li Ming did not explain it. After all, the texts on the books signed in the system are almost all his notes. As his cheap dad, Li Shimin can certainly tell it at a glance.

.

"My son understands."

"My son, I just accidentally discovered during this period that some of the liquid in the toy was mixed with lard, and it actually exploded, so I finally figured it out after repeated attempts."

The figure nodded, and Li Ming casually briefly told how he discovered the nitroglycerin explosive.

It also prevents my father from continuing to ask questions.

As for this reason, he can show it even if he wants to get to the bottom of it.

This is almost the same step as the discovery of nitroglycerine in the previous life, and there will be no problems.

"Hmm!"

"But be careful next time, the "explosives" you made are very dangerous!"

After nodding, Li Shimin was silent for a moment, then spoke softly and did not continue to ask further questions.

"My son, I understand."

Hearing these seemingly caring words, Li Ming was a little surprised, but he still responded quickly with gratitude.

The father and son were talking.

In my memory, it seems that I have never been so kind.

He couldn't help but feel a little happy in his heart.

While the two were talking.

The other side.

Qin Qiong quickly mobilized troops.

No one dared to leave under Yuchi Gong's guard.

Of course, everyone in the palace at this time had no idea what was going on.

At this moment, everyone couldn’t help but worry about punishment.

Only Zhao Jing was a little confused.

But he didn't dare to ask.

I don’t even dare to do anything.

Soon, people were in panic.

They were brought back to the palace.

And soon only Qin Qiong, Yu Chigong, Wang De, and Li Ming were left in the entire Prince Cao's Mansion.

Qin Qiong and Yuchi Gong, who had returned at this time, couldn't help but look at Li Ming frequently.

King Cao, this is a prince they didn’t care about at all.

Compared to the prince's attention and the dazzling looks of several other princes, this one seems to have no sense of existence.

Even if it hadn't been for the opening of the palace a few days ago, I'm afraid no one would have remembered that Li Shimin had such a prince.

But they didn't expect that today would give them such a big impact.

In the scene in the small yard, even at this moment, they seemed to feel their scalps going numb.

Even if they are powerful, it would be almost impossible to escape the scope of the explosion.
