Li Chenghua looked at Li Shimin so shocked?

Then, he shrugged and said, "I said [King of Jiangxia], you don't have to be so shocked, right?"

This is just a few acres of land!

There are 1,000 acres of potatoes behind it!

However, these 1,000 acres of potatoes will not mature in a month!”

"What? There are 1,000 acres left?"

Li Shimin was extremely shocked and said, "1,000 acres, how many potatoes do you have to produce?"

Li Chenghua looked like Li Shimin who was injected with chicken blood, and the stunned Li Jing and Cheng Yaojin?

Then, he said calmly: "You really need to learn mathematics well!

As I said just now, is it calculated as 5,000 kilograms per acre?

That 1,000 acres is 5 million jin!”

The output Li Chenghua mentioned was based on the [mu] and [jin] of the Tang Dynasty.

One acre of the Tang Dynasty is about 0.9 acres in the 21st century.

A pound of Tang Dynasty is heavier than a pound of future.

However, the difference is not particularly large.

"5 million jin?"

Li Shimin sat on the ground with a thump!

Then, he murmured a little in dismay: "5 million jin?

If these 5 million kilograms of potatoes are kept as seeds, they will be planted in various parts of the Tang Dynasty?

Then this output...is enough to change the fate of the people of the Tang Dynasty!"

When Li Chenghua took out the konjac before, Li Shimin was not as excited as he was now!

Because, konjac is poisonous!

It is still difficult to let ordinary people remove the poison of konjac!

But potatoes are different!

Potatoes have a shorter growth cycle than konjac! And aren't poisonous?

Therefore, this is more suitable for promotion in the entire Tang Dynasty!

Li Shimin is so shocked at this moment?

Needless to say, Li Jing and Cheng Yaojin!

In short, this magical potato? The 1,000 acres of potato yield completely shocked the three of them!

Looking at the expressions of the three people, Li Chenghua smiled and said, "Okay, let's talk about Tudou later!

Don't worry, have these 1,000 acres of potato seeds?

In the future, it will always be slowly promoted to the entire Tang Dynasty!

Well, I asked you to come today to let you see an epoch-making weapon!”

"An epoch-making weapon?"

Hearing Li Chenghua say this, Li Jing's eyes shining: "Chenghua, do you mean there is a weapon that can change the way of war and the end of war?"

Li Chenghua gave Li Jing a thumbs up and said, "No, General Li is still responding quickly!"

Get a positive answer from Li Chenghua?

Li Shimin, who came to his senses, was extremely surprised and said, "What? There is such a powerful weapon?

So Chenghua, is this weapon compared to potatoes? Which one do you think is more important?”

Lee Seung-hua waved his hand and said, "This is different!

Potatoes can solve the problem of food and clothing.

The mysterious weapon I mentioned? That can change the issue of national security!

It can even change the world's pattern!"

“…”

Looking at the three people who are silly again?

Li Chenghua smiled and said, "There is a saying in the Book of Changes - if you have any words, you don't believe it!

That means I just said it was useless!

Let's go, I'll take you to see how powerful this weapon is!"

"Okay, go, then leave!"

At this moment, Li Shimin urged Li Chenghua to see the mysterious weapon as soon as possible.

Next, Li Chenghua and his group arrived at a quarry!

Taohua Village is at the foot of Zhongnan Mountain.

Therefore, there must be a quarry.

After coming to the quarry, Li Jing was a little confused and said, "Chenghua, this...

Didn’t we tell us what weapons? Why did we come to the quarry?”

Li Chenghua pointed to the craftsman who was mining stones on the top of the mountain and said, "General Li, do you think these people who mine stones are very hard-working?"

Li Jing smiled bitterly and said, "Of course it's hard! Who doesn't know?"

Cheng Yaojin said: "Yes, I have mined stones!

Do you need to use an iron drill and a sledgehammer to dig out the stone?

This is not ordinary hard work!

Sometimes, no matter how tired you are, you can’t mine many stones in a day!”

Li Shimin looked at the stone on the top of the mountain and suddenly said, "Chenghua, you won't develop a weapon that can mine stones, right?"

Li Chenghua smiled and nodded and said, "It's almost the same! A weapon like me can greatly speed up the mining of stones!"

“…”

Listen to Li Chenghua saying this?

Li Shimin was a little confused again: "But, why do you need so many stones?

The stones here are not suitable for building grand palaces!

Besides, there are no new large palaces built in the Tang Dynasty now.”

The stones picked in the quarry in front of me are actually a bit fragmented.

Li Chenghua smiled slightly and said, "The gravel that will be mined here in the future is not for the construction of palaces!

It is used elsewhere.

Okay, let’s not talk about stones anymore! Let you see the power of [Epoch-making Weapons]!”

After saying that, Li Chenghua waved his hand.

Then, Liu Ruiting immediately directed people and prepared to conduct the experiment.

What is this epoch-making weapon that Li Chenghua mentioned?

Of course it's gunpowder!

But for this primary gunpowder?

Li Chenghua is actually not very interested!

However, Li Chenghua could not have brought out the most advanced gunpowder he had.

If that?

That will really bring chaos in the world!

Walking forward, Li Chenghua checked the leads of these gunpowder and gunpowder.

To create a fuse that can burn in water in this era?

This is still very difficult!

However, making a gunpowder lead that can prevent moisture? This is not difficult!

At this time, Li Chenghua said to Cheng Chumo: "Chumo, I will tell you that the hole you punched is done?"

Cheng Chumo immediately said: "Brother, it has been laid. According to your requirements, the thickness and depth of these holes are different!"

Li Chenghua stepped forward and checked, "This is still too shallow, deepen it a little more!"
