To tell the truth, even the explosion of black powder with sugar was not very powerful.

The crater created by about two catties of explosives is less than one meter in diameter and only half a foot deep.

More than a meter of the grass around the crater has been burned to ashes, and there are other signs of burning.

Li Zhi also looked around for some fragments formed after the explosion.

These fragments were found to be concentrated within a radius of three or four meters.

Li Zhi roughly estimated that such a bomb could only kill people within two meters of the surrounding area.

After this experiment, he was not very satisfied with the power of the explosives.

In his opinion, the damage that such explosives can cause even if they are thrown into the battlefield is limited.

Rather, it may be more of a deterrent to the enemy.

But he thought about it again and felt that this effect was okay.

Because most of today's wars are battles between siege battles and battle formations.

In such a battle, the personnel are relatively dense, and the main thing for both sides is to fight.

In such a situation, the deterrent effect of these explosives is immeasurable.

In addition, most of Datang's current neighbors are dominated by cavalry, and these bombs can frighten the war horse to a great extent, so that the enemy loses control over the war horse.

Next, Li Zhi asked Liu An to try to blow one up, and after finding that the effect was almost the same, Li Zhi took Liu An back with no interest.

Liu An himself was frightened by the bomb, and his mind is still recalling the scene of the explosion.

But he was suddenly surprised to find that his little master didn't seem to care much about all this.

So he asked suspiciously, "Your Highness, isn't Your Highness surprised that the power of this thing is so huge?" ”

Li Zhi said depressedly: "This thing is too far from the power imagined by Xiao Wang, it is simply too disappointing." ”

After hearing this, Liu An said in shock: "In the eyes of the minion, this thing is already against the sky, and His Highness is still not satisfied?" ”

Li Zhi said: "This king thinks that its power should be twice as great. ”

Liu An was taken aback by Li Zhi's words, and the current one had already had a great impact on his psychology.

If it was doubled, wouldn't it scare people to death?

Thinking of this, he glanced at Li Zhi a little strangely.

He suddenly felt that his little master was a little too cruel.

Li Zhi didn't know at this time that due to the difference in knowledge, his thoughts had been labeled as brutal by Liu An.

After he returned to the palace, he immediately sorted out a secret recipe for the manufacture of gunpowder and handed it to Li Shimin.

By the way, he also handed over the remaining two sake jars to him and told him how to use them.

In his opinion, this thing is better than nothing, so he has completely lost interest in black powder at the moment.

He was now ready to tinker with refined salt and sucrose.

In his opinion, at least these two successes can bring some benefits to the people of Datang in the future.

However, what he didn't expect was that what he didn't like was being tightly surrounded by Li Shimin and a group of ministers at the moment...

Li Shimin's current attention to Li Zhi can be described as extraordinary.

Because he has unconsciously brought too many surprises to Li Shimin.

Therefore, when Li Zhi handed over the recipe of black powder and the prepared bomb to Li Shimin, Li Shimin immediately asked the guards to take one and do a test explosion.

Because Li Zhi was too casual when explaining the characteristics of black powder, Li Shimin did not deliberately choose a secluded place.

They found a random open space outside the Taiji Hall and lit a wine jar.

So when the loud explosion sounded, almost all the officials of the three provinces and six ministries who were going to work nearby were alarmed.

Rao is a battle-hardened ruthless person like Li Shimin, who was terrified by the huge explosion.

The entire Taiji Hall soon fell into chaos in front of the door.

First, the surrounding guards quickly ran over and blocked in front of Li Shimin.

Next, Li Jing, who was born as a military general, quickly rushed out violently.

Behind him were Fang Xuanling, Wang Qi and a few younger officials.

And then there were other officials with all sorts of "weapons" in their hands.

Some of them had an inkstone in their hands, some had a broom, and some even held a vase.

Li Shimin, who came back to his senses, saw this situation and hurriedly shouted: "You Aiqing don't need to panic, I'm fine..."

Due to the chaos and commotion at the scene, Li Shimin shouted several times before finally persuading the crowd.

Next, he hurriedly sent most of the people back, leaving only Fang Xuanling and the others who were confused.

Li Shimin didn't dare to delay at this time, and hurriedly told them what had happened.

In the end, he said to a few people with an apologetic face: "I am really sorry that I disturbed you because I did not think about this matter. ”

After saying this, he clenched his fists and arched his hands to everyone.

Fang Xuanling and the others were all relieved after listening to Li Shimin's explanation.

Then everyone began to carefully observe the situation at the scene of the explosion.

Since the front of the Taiji Hall is paved with floor tiles, the power of the explosion is more intuitive.

At this time, there was a small pit with a diameter of about half a meter at the scene, and the surrounding floor tiles were either blown up or overturned.

The depth is not very deep, just the height of a brick.

There are a lot of debris scattered within a radius of three or four meters in the vicinity, and there are very few of them on the periphery.

But even that was enough to shock everyone at the destructive power of black powder.

Because there has never been a product that can cause such destruction without relying on human labor.

After observing for a while, a few people began to discuss around one of the remaining wine jars.

Li Jing opened his mouth and asked, "Your Majesty, should we open it and take a look?" ”

Fang Xuanling stopped: "This thing is so dangerous, I think it is better to be careful." ”

Wang Jue said to Li Shimin: "According to the minister, since this thing is made by His Royal Highness the King of Jin, it is better to find him and explain it in detail." ”

Li Shimin was just startled by the sound of the explosion, and his liver is still plopping with caution.

After listening to Wang Jue's words, he thought for a while and then nodded: "What Shu Jue said is reasonable, it is better to let the pheasant slave explain it clearly." ”

So Li Zhi was soon called to the front of the Taiji Hall and personally became a commentator.

He explained the properties of gunpowder as he opened the jar.

Then, in the frightened eyes of everyone, he directly took out a handful of gunpowder from it.

Everyone looked at Li Zhi's outstretched palm timidly and curiously, and found that it was just a handful of black earth.

Seeing this, Li Jing first said suspiciously: "This thing is so ordinary?"

Li Shimin said: "Although the appearance of this thing is ordinary, I am afraid that the use is not small. ”
