"OK! Since you want to hear it, I tell you, let alone the red cannon. This thing is still my brother. If I have time, when my research institute is finished, let alone the red cannon, I can make fire guns and firearms easier than bows and arrows."

"These are pediatrics. After I train some technical talents, I'll get you all the bombs."

While talking, Zhang Feng's voice suddenly stopped.

"But look at my construction site. It's all a big mess. How do you want me to make these things for you?"

"I have time and space!"

"Even the simplest fire gun, although I said it could be made in a month, it also needs space and time, doesn't it? I'm not an immortal. I also want to change it for you at once, but do you think it's possible? It all takes time!"

Li Shimin has long been dizzy.

The more he listened, the more he felt that these things were farther away, and he gradually understood what Zhang Feng meant.

The goods are turning the corner and scolding me for being short-sighted?

But even if he knew it, Li Shimin couldn't raise his mind to find the venue. Zhang Feng's last remark about the fire gun has aroused Li Shimin's strong interest

"Feng Zi, tell me about this fire gun."

"What are you talking about? No matter how much you talk, you don't have time to do it now!"

"No, tell me. I remember I had a funny idea from the previous dynasty, like the personal sword of the Sui Yang Emperor..."

As soon as he heard the baby, Zhang Feng's ears suddenly branched up: "bring it, I'll tell you!"

Li Shimin smiled.

"You say it first."

"Are you sure this thing is really the personal sword of the Sui Yang emperor?"

Zhang Feng's eyes were burning.

Sui Yangdi!

Before he became the emperor, this ox man was also a very powerful person. Unfortunately, he was unlucky in the end and was rolled down.

There are only a few rumors about the Sui Yang emperor in later generations.

But at this time, Zhang Feng actually heard the personal sword of the Sui Yang emperor?

How can this keep him from moving?

This thing, anyway, is used by the emperor. It's also a symbol of identity.

I can't help it. Zhang Feng doesn't care about Li Shimin's encouragement. If you had this baby, you would have said it!

You said it earlier. I'll tell you everything.

"Cough, if you want to say this fire gun, the principle is very simple, and the manufacturing process is not very complex. The most important thing about this thing is simplicity. How many arrow clusters can ordinary archers assemble when they go to the battlefield?"

When Li Shimin heard the speech, he said, "it's usually thirty. If there are light cavalry, there are about forty."

"By the way, just hit 50 arrow clusters. It's all about weight. It's too heavy and affects speed. It's too little. It's not enough. It's the weakness of archers, but once you replace it with a fire gun, these are not problems. You should know that the firecracker, Lao Li? The ammunition of this thing is gunpowder!"

"The impact of gunpowder will push the iron sand to launch in a short time. The strong impact can easily penetrate the general armor. The strong impact can even shoot through the horse!"

Li Shimin was shocked.

However, as soon as Zhang Feng's painting style changed, he asked, "is it all right to take a kilogram of gunpowder alone? As long as the proportion of gunpowder is fixed in advance and the gun barrel is inserted when it needs to be used, a kilogram of gunpowder and five kilograms of iron sand, I think it should not weigh 30 arrow clusters?"

"How many times can you exchange five kilograms of iron sand with one kilogram of gunpowder?"

Where does Li Shimin know?

Zhang Feng stretched out three fingers and shook them in front of Li Shimin.

Li Shimin said, "thirty... Three hundred times?"

"Yes!"

Li Shimin was completely speechless by Zhang Feng's words.

But Zhang Feng kept on saying, "and the most important thing about this thing is a seamless steel pipe. If there is something and a smelter, I can make you a fire gun now!"

"Seriously?"

When Li Shimin heard the speech, his spirit came in an instant.

Zhang Feng was stunned and nodded subconsciously.

Seeing this, Li Shimin grabbed Zhang Feng's arm and pulled it out.

Zhang Feng was startled.

"Lao Li, we have something to say. Why did you pull me?"

"Let's go to Chang'an city. I'll find you the top blacksmith in Chang'an! Even if what you say is true, I can get it for you, even the smelting master of the Ministry of work!"

When Zhang Feng didn't say the production process of this thing, Li Shimin was really a little lost, but now?

No doubt it was a chance to survive!

As long as there is a smelter, he can get it out?

What are you waiting for?

As long as he gives an order, how many blacksmiths in Datang can not come?

what is it?

At present, the war is tight, and no one knows what will happen and what changes will happen on the front line. If we can deploy a big killing weapon earlier at this time, it will be an overwhelming guarantee for the whole war situation.

Li Shimin also saw that the Tang Dynasty could not be defeated.

Once the war is defeated, the Turkic cavalry will not be the only one facing Datang.

But everyone.

Therefore, Li Shimin wants to draw a perfect picture in his political career with a perfect war!

At this time, the fire gun is his hope.
