the next day.

Li Chenghua was still sleeping in Mingyue Tower, but Cheng Yaojin knocked on the door and came in.

After Li Chenghua opened the door, he said, "Uncle, what's wrong with it so early? Haven't I agreed on gunpowder?"

Cheng Yaojin said: "Well, His Majesty just sent someone to say that gunpowder should continue to hold on!

What stone should I use gunpowder to blow up?

What are you doing with gunpowder?”

Li Chenghua was stunned for a moment, then smiled and said, "It seems that Ma Zhou's plan for water conservancy will show His Majesty?

Well, what are you doing about rock-fried? You will understand in the future!

Well, since you have to hurry up, let’s go and check if some equipment has been made?"

Cheng Yaojin nodded and said, "Then let's go!"

On the way, Cheng Yaojin was a little puzzled: "Chenghua, military weapons surveillance can also be used as surveillance equipment, why do you need to find a general to serve as a surveillance?"

Li Chenghua said: "Because, the overall level of the supervisor will be better!

Uncle, gunpowder is powerful!

Whether it is production or future use?

All require some metal devices.

These metal devices will now be used as supervisors and military equipment supervisors. I want them to build them to see who is more advanced!

Production equipment may be simpler.

But those equipment that can fire gunpowder is more complicated!

According to my speculation, I'm afraid neither of these two places will meet the standards!"

Cheng Yaojin said in surprise: "No way?

There are still many powerful craftsmen who will work as supervisors and military weapons supervisors!

It shouldn't be a big problem to create a gunpowder-launched device, right?"

Li Chenghua shook his head and said, "Uncle, it's not that simple.

Before, you have also seen the power of gunpowder!

Therefore, those metal objects that emit gunpowder must be very strong!

Moreover, constant strength requires a certain degree of resilience!

Of course, the problem of heating during use must also be considered.

If it is made carelessly and the quality is not up to standard, the metal object will explode!

If that happens, not only will it not be able to defeat the enemy, but it will also injure us Tang Dynasty soldiers!

In short, according to the current level of technology, if they don’t improve, that’s really not possible!”

What Li Chenghua said is of course a simple artillery!

In this era, to be honest, building artillery is easier than making muskets!

Making muskets, especially more advanced muskets, sometimes the barrel needs to be rifled!

This is very difficult for the technology of the Tang Dynasty.

Of course, this is a pediatrics for the technology of Taohua Village!

It is easy to make guns in Taohua Village.

However, in order to avoid affecting this historical time and space, Li Chenghua did not make it on a large scale!

"Ah, it's so complicated? What should I do?"

Niu Jinda was anxious. This was like painting cakes to satisfy hunger. It made people anxious, but they couldn't eat it.

Li Chenghua shook his head and said, "What should I do? Go and have a look before doing it!

Now I don’t know how high the level of metal smelting and building of military equipment will be…”

While talking, they arrived at the Military Equipment Supervision.

When Niu Jinda heard that Li Chenghua was looking for a master here, he immediately went to call someone.

Not long after, Niu Jinda brought an old craftsman and said, "Chenghua, this is Zheng Wujiancheng of the Military Arts Supervision.

Just tell him about metal objects."

Zheng Wu smiled bitterly and said, "General Niu, I have never seen the power of gunpowder. How can I guarantee that I can build it?"

Gunpowder had just developed in the early Tang Dynasty and had not yet been used to make firecrackers, but just set off fireworks.

Therefore, although Niu Jinda described the power of gunpowder explosion to Zheng Wu?

However, Zheng Wu still didn't believe that he had to see it with his own eyes.

Li Chenghua said: "Zheng Jiancheng, do you want to measure the explosive power of gunpowder based on the standards of military weapon supervision? Then predict whether it can be made of which metal object?"

Niu Jinda said: "Chenghua, then let's demonstrate it again! After all, yesterday we exploded the big tree and exploded the stones on the mountain, and Zheng Jiancheng did not see it with his own eyes."

Lee Seung-hua said: "Okay, let's do another experiment!

However, how powerful gunpowder is, I'm afraid Zheng Jiancheng cannot measure it. It mainly depends on your experience."

Zheng Wu smiled and said, "Don't worry, brother Chenghua, as long as I see the power, I will know it."

Li Chenghua nodded and went out to the gunpowder warehouse guarded by heavy troops.

After all, Li Chenghua has stored the hundreds of kilograms of gunpowder here.

Li Chenghua pointed to the gunpowder and said, "Zheng Jiancheng, have you seen this kind of gunpowder before?"

Zheng Wu looked carefully, shook his head and said, "I have never seen it, what kind of configuration is used?"

"Zheng Jiancheng, this configuration is simple. In fact, this thing was created when Taoist alchemy was refining."

Of course, Li Chenghua can't talk about the formula.

Zheng Wu also realized that he was talking too much, so he smiled and said, "Oh, Taoism? It seems that I am ignorant!"

Lee Seung-hwa smiled and said, "Let's demonstrate now!"

Li Chenghua put the gunpowder in a pottery pot to seal it, then went out and buried it in a pit with a pile of big stones on it.

Gunpowder must be sealed to explode. If it is not sealed, it is just a fireworks.

Li Chenghua asked everyone to retreat, then lit the fuse, and ran to a safe distance.

Looking at the gunpowder leads splashing in the distance, Zheng Wu didn't know what it was. He just wondered how this gunpowder would explode and what the explosion effect would be!

At this moment, there was a loud bang!

The huge rocks pressed on the mound of soil in the distance flew into the sky! The soil also flew high and fell everywhere. The sky was filled with dust!

Cheng Yaojin and Niu Jinda had just seen such a loud noise yesterday, so they are still calm now.

However, Zheng Wu was not calm at all! He was completely shocked by the explosion effect!

After rubbing his eyes and confirming that there was a real scene in front of him, Zheng Wu was so excited that his whole body was trembling!

Li Chenghua smiled and said, "Zheng Jiancheng, how effective is it?"

Seeing the big stone flying far away, Zheng Wu said excitedly: "It is powerful, powerful!

Oh, so it seems that it is very difficult for us to create that metal object, after all, this gunpowder is amazing!"

Lee Seung-hua said: "Then let's build equipment for producing gunpowder first!

As for those equipment that fire gunpowder? Look at these drawings..."

Three days later, under the guidance of Li Chenghua, the first batch of gunpowder was finally produced!

Then Li Chenghua asked Cheng Chumo to take people to blow up the stones and prepare to lay the canal!

But soon, Cheng Chumo came over and told Li Chenghua that they encountered a lot of things when mining the rocks! Several accidents occurred!

They are all a little helpless now.

If these are accidents that cannot be avoided and are impeached by the censor, it will be troublesome.
Chapter completed!
