The next day, Liu Minghua was still sleeping, and Niu Jinda knocked on the door and came in.

After Liu Minghua opened the door, he said, "Uncle, what's the matter so early?" It will take two hours for Your Majesty to arrive, right? ”

Niu Jinda nodded and said, "Well, just now His Majesty sent someone over to check the power of gunpowder." Also, His Majesty said before that if gunpowder is amazingly powerful, let me ask you, can't it really be used in the military? ”

Liu Minghua closed the door and said: "Uncle, you have also seen the power of gunpowder, if I say that gunpowder cannot be used in the military, I am afraid that you will not believe it." So I'm just going to say – yes! But, not now! ”

Niu Jinda was excited: "Why not now?" ”

Liu Minghua asked Niu Jinda to sit down and said, "Because, the level of supervision and ordnance supervision is not good now." Uncle, you know what? Gunpowder, which can be fired from a distance! But for long-range launches, some metal devices are needed. These metal devices cannot be built by the Prison and the Ordnance Supervisor now! ”

Niu Jinda was disappointed and said, "Won't it?" There are still a lot of powerful people in the Ordnance Warden, right? Crafting something that shoots gunpowder shouldn't be a big problem, right? ”

Liu Minghua shook his head and said, "Uncle, it's not that simple. You saw the power of gunpowder yesterday! Therefore, the metal object to be used to fire gunpowder must be very strong, and it must also have a certain toughness, and it must also take into account problems such as heat. If it is built so-so and the quality is not up to par, this metal object will explode and not only fail to hit the enemy, but also injure our own people. All in all. According to the current level of science and technology, it is really not good! ”

"What then?" Niu Jinda got anxious. It's like painting bread to satisfy hunger. It makes people look anxious, but they can't eat it.

Liu Minghua shook his head and said, "What should I do?" I still don't know how high the level of metal smelting and crafting is in the Ordnance Supervisor. I really don't know what to do......"

Before Liu Minghua finished speaking, Niu Jinda stood up and said, "Minghua wait a minute." After saying that, Niu Jinda went out.

Liu Minghua was a little stunned, so he could only sit there and wait.

After a short time, Niu Jinda brought an old craftsman and said: "Minghua, this is Zheng Dixin, the supervisor of the ordnance superintendent." Just talk to him about some metal object or something. ”

Zheng Dixin said with a smile: "Little brother Minghua, I was ordered to come over to check the power of gunpowder. Then let people go back to the palace to recover...... You see. When do we realize the power of gunpowder? ”

"Ahh Do you want to see the effect in advance? Liu Minghua was stunned, not knowing what Li Shimin was doing.

Niu Jinda hurriedly said: "Ah, the power of this gunpowder will be seen later." Zheng Jiancheng and Minghua said that gunpowder can be fired with a metal object. I don't know if the ordnance supervisor can be built? ”

Zheng Dixin smiled bitterly: "General Niu." How powerful is gunpowder. I haven't seen it before, so how can I guarantee that I can build it? ”

Gunpowder was only just developed in the early Tang Dynasty, and it had not yet been used to make firecrackers. It's just fireworks. Therefore, although Niu Jinda described the explosive power of gunpowder to Zheng Dixin, Zheng Dixin still did not believe that he had to see it with his own eyes.

Liu Minghua said: "Zheng Jiancheng, do you want to measure the explosive power of gunpowder by the standard of the Ordnance Supervisor?" And then predict if you can make that kind of metal object? ”

Niu Jinda said: "Minghua, then let's demonstrate it again!" After all, yesterday we blew up the big tree, and Zheng Jiancheng didn't see it with his own eyes. ”

Liu Minghua said: "Okay, let's do another test!" However, I am afraid that Zheng Jiancheng will not be able to measure the power of gunpowder, it mainly depends on your experience. ”

Zheng Dixin said with a smile: "Little brother Minghua, don't worry, as long as I see the power, I will know it." ”

Liu Minghua nodded, and went out to the heavily guarded gunpowder warehouse.

Liu Minghua pointed to the gunpowder and said, "Zheng Jiancheng, have you ever seen this kind of gunpowder?" ”

Zheng Dixin looked at it carefully, shook his head and said, "I haven't seen it, what is this configured with?" ”

"Zheng Jiancheng, this configuration is simple. In fact, when the Taoist alchemy, he once made this thing. "Of course, Liu Minghua can't say the formula.

Zheng Dixin also noticed that he was talking too much, so he sneered: "Oh, Taoist? It seems that I am lonely and unheard! ”

Liu Minghua smiled and said, "Let's demonstrate now!" ”

Liu Minghua sealed the gunpowder in a clay pot, then went out and buried it in an earthen pit with a pile of large stones on it.

Gunpowder must be sealed in order to explode, and if it is not sealed, it is nothing more than fireworks.

Liu Minghua asked everyone to retreat, then lit the fuse, and then ran to a safe distance.

Looking at the fuse of sparks in the distance, Zheng Dixin didn't know what it was. He just wondered how this gunpowder was going to explode, and what the effect of the explosion was!

At this moment, there was a loud bang!

A boulder pressed against the mound of earth in the distance flew into the sky! The dirt also flew high and fell everywhere. The sky is dusty!

Such a loud noise, Cheng Yanjin and Niu Jinda had just seen it yesterday, so they are quite calm now.

It's just that Zheng Dixin is not calm at all! He was completely shocked by the effect of this explosion!

After rubbing his eyes and making sure that the scene in front of him was real, Zheng Dixin was so excited that he was trembling all over!

"Hurry up, go back to the palace to report to Your Majesty, just say that this gunpowder is amazingly powerful, earth-shattering, it is simply indescribable!" Zheng Dixin said to a forbidden army.

"Good!" The forbidden army is responsible for reporting the actual effect.

Liu Minghua smiled: "Zheng Jiancheng, how is the effect?" ”

Seeing the boulder flying far away, Zheng Dixin said excitedly: "The power is huge, the power is huge!" Oh, it would be so hard for us to make that metal object, because the gunpowder was incredibly powerful! ”

Niu Jinda was disappointed for a while, and then said, "Hey, I'll talk about it later." Minghua, do you want to arrange it at this moment? Majesty should be coming soon! ”

Liu Minghua said: "Okay, let's go and arrange it." ”

…………

Two hours later, the Tang Emperor Li Shimin came to the barracks with a group of civil and military ministers.

"Haha, Minghua, it is said that gunpowder is amazingly powerful? Hurry up and demonstrate, let me and you Aiqing see it! Li Shimin was in a good mood when he saw Liu Minghua.

"Your Majesty, you ...... With so many ministers coming, if the demonstration fails, then I will be embarrassed! Only then did Liu Minghua understand why Li Shimin asked Zheng Dixin to come over in advance to check the effect of gunpowder.

Li Shimin smiled: "Aren't you known as the 'Son of God from the Sky'?" Is there anything you can't do? Hugh wants to talk nonsense, hurry up and demonstrate! ”

Liu Minghua smiled bitterly, took the flag, and waved it a few times on the top of the mountain.

At this moment, a group of ministers are talking to each other, they heard Li Shimin say that there is something that can explode a boulder? Of course they didn't believe it, so everyone was looking forward to seeing if there was anything so powerful in the world.

Dozens of seconds have passed, and why is there no movement on the mountain?

Li Shimin got up from his seat a little anxiously, walked to Liu Minghua's side and said, "Boy, why hasn't it exploded yet?" Could it be that you were on a business trip? I ......"

When Li Shimin said this, he heard a boom!

Accompanied by an earth-shattering bang, the earth shook violently!

Then, everyone was stunned to see that a cliff in front of them suddenly collapsed! Boulders are splashing and dust is flying!

"This ......" Li Shimin was dizzy for a while, stunned by this earth-shattering reality!
