Everywhere in the lush Chu Prince's Mansion has its own unique wonders.

However, Li Shimin was focused on the black gunpowder and was not in the mood to appreciate it.

"Your Majesty, you can't go any further. We will stand here. When Liu Yuan is ready, we will be able to see the power of black powder."

Next to a special reinforced concrete wall, Li Kuan stopped Li Shimin from walking forward.

"Kuan'er, Liu Yuan is still a hundred steps away from us. What's there to worry about? He can't see clearly even if he's too far away."

Although Li Shimin saw the power of fireworks in the opera house today, he was sitting directly in the front row.

According to his estimation, even if the black powder that Li Kuan created now was more powerful, he wouldn't be able to watch it from a hundred steps away, right?

What can you see from this far away?

"Your Majesty, a hundred steps is already a bit dangerous. Let's wait behind this wall first. There are two special viewing holes here."

In order to let Li Shimin fully realize the power of black powder, Li Kuan asked Liu Yuan to prepare several kilograms of black powder, and it was a high-quality product made in a laboratory.

The distance of one hundred steps seems quite far, but in fact it is less than one hundred meters, so it is not very safe.

If you are unlucky and a piece of gravel flies in and injures Li Shimin, it will be great fun.

Of course, Li Kuan was more worried about being hit.

"Your Highness, King of Chu, this is not your style. After all, you have fought against Tuyuhun and been to Japan. Why are you so afraid of death now?"

Yu Chigong, who followed, couldn't help but complain.

"Jingde, His Majesty the King of Chu, this is for the sake of His Majesty's safety. You must not talk nonsense."

Qin Qiong made an exception today and went out to watch "The Legend of White Snake", and then followed him to the annex of Prince Chu's Mansion with a curious look on his face.

Speaking of which, this was his first time here, and he didn't expect that there was such a large-scale courtyard outside Chang'an City.

"Hey, this is it."

Yuchi Gong had always respected Qin Qiong, his elder brother, and now that he saw him speaking, he naturally behaved like a kitten.

"Everyone stand behind the wall and the fire will start soon."

Li Kuan saw Liu Yuan signaling from a distance that he was ready, and quickly told everyone to hide.

Those who came here today are all important ministers of the DPRK. No matter who has an incident, they will not be able to communicate with each other.

Li Kuan didn't want to turn a good thing into a bad thing.

"Mysterious!"

Changsun Wuji muttered, but still followed everyone behind the wall.

"If nothing unexpected happens in a while, I will be completely embarrassed by you."

Cheng Yaojin also looked at Li Kuan with a speechless expression, feeling that he was making a fuss out of a molehill.

"Junmai, inform Liu Yuan that it's time to start." Li Kuan said to Xi Junmai, and then reminded him again, "Your Majesty, all princes, please cover your ears. You must cover your ears."

After Li Kuan finished speaking, he covered his ears first, regardless of whether everyone believed it or not.

When Li Shimin saw this scene, he also covered his ears in disbelief.

"boom……"

After a while, there was a loud noise from ahead.

Even if everyone covered their ears, they still felt their whole bodies buzzing, the ground seemed to be shaking, and they even heard a few screams.

Obviously, some of the guards who were unable to stand behind the wall were accidentally hit by the debris thrown up by the black powder explosion.

"This...is this the power of black gunpowder? It's even more powerful than the thunder and lightning."

Although Li Shimin was frightened, he quickly regained his composure.

After all, we already knew in advance that this was man-made.

However, Li Junxian was patrolling the perimeter with the Qianniu Guards. He didn't know the specific situation inside, and suddenly heard such an earth-shattering sound. His face turned pale.

He quickly mounted his horse and rushed into the palace of Prince Chu.

"His Majesty!"

Seeing that Li Shimin was safe and sound, Li Junxian finally breathed a sigh of relief.

"You guys just get out."

Li Shimin had already felt the power of this black powder. Thinking back to the time when he came here just now, many people Li Kuan refused to follow. Naturally, he didn't want too many people to know about it now.

"Your Majesty, Wei Chen, please go over and take a look at the situation at the explosion site."

Qin Qiong was eager to try it and had already seen the military use of black gunpowder.

Li Shimin: "Kuan'er, it won't explode again, will it?"

Li Kuan: "No, black powder is a disposable item. After one explosion, nothing will be left."

"Then let's all go over and see how powerful this black powder is."

After Li Shimin finished speaking, he walked out of the wall and headed towards the place where Liu Yuan had filled the black powder.

The distance of a hundred steps is only a matter of a few breaths.

However, when a large pit about one foot wide and half a person deep appeared in front of everyone, the air seemed to freeze a little.

After a cup of tea, Li Shimin finally spoke, "This place was originally flat land?"

"That's right, it was originally a flat land that was leveled with yellow mud and gravel."

Li Kuan naturally understood the meaning of Li Shimin's words.

"Your Highness King Chu, is it possible to make this black powder into a weapon like a kerosene bomb, and then throw it towards the enemy and then explode?"

Although Qin Qiong's lung disease has recovered, he still looks thin due to years of illness. However, when he said this, his face was excited, which made Li Kuan worried that he would not faint.

"Yes, my dear son-in-law, this black gunpowder is so powerful. If it is used on the battlefield, even if it doesn't kill many people, the sound alone will be enough for someone to eat a pot."

Cheng Yaojin's eyes also shone, and he felt that the black powder was really a good thing.

"It's possible, but there are many restrictions on the use of black gunpowder. It doesn't mean you can win the battle with it."

Black gunpowder had been used on a large scale to equip some armies in the Song Dynasty, but the Song Dynasty still could not defeat the Jin Kingdom, Xixia, and Mongolia.

Li Kuan didn't want everyone to pin the outcome of the war on black weapons.

After all, this is just a relatively primitive form of gunpowder. The first time it is used, the effect may be a little more significant. But once the enemy is familiar with this situation, the effect will be greatly reduced.

Besides, large-scale production of black powder is itself a troublesome matter.

Whether it's storage or transportation, it's a big problem.

It would be ridiculous if none of the enemies have been killed by then, and you will be killed and injured a lot, so that ordinary soldiers dare not use it.

"Kuan'er, does anyone know how to make this black gunpowder?"

Li Shimin looked at the big pit in front of him attentively, constantly thinking about the pros and cons in his mind.

First of all, the production method of this black gunpowder must be highly confidential. Whether it is for your own safety or to avoid spreading to enemy countries, this is necessary.

Secondly, since this thing has been produced, it must be mass-produced to be of practical significance. Where to arrange the production and who is responsible is also a problem.

When you come into contact with such a secretive person, you are bound to not have much freedom.

Finally, should I consider nipping this black powder in the bud?

Li Shimin had not considered this idea, but finally gave up.

Based on his understanding of Li Kuan, he knew that no matter what he did, he had a purpose.

Now that black gunpowder has been produced, he must have thought that this thing would do more good than harm to the Tang Dynasty.

"Your Majesty, the current black powder is produced by Weichen's son Liu Yuan."

Li Kuan must know it himself, and Li Shimin himself certainly knows it.

"I want to set up a special gunpowder bureau to be responsible for making black powder and related weapons. What do you think?"

"Your Majesty, the black powder is of great importance, and it must be handled by a special court office. Once it is determined, the minister can ask Liu Yuan to give guidance first."

"Well, today's matter will be kept secret for now. No one can spread it at will."

Faintly sensing the importance of black powder, Li Shimin felt that he had to discuss what to do with several important ministers.

However, no matter what the final result is, there is no harm in keeping today's matter secret.

Seeing that the sun had set, Li Shimin rejected the offer to stay in the Chu Palace for a meal and drove back to the palace.
