The emperor held a spring ploughing ceremony and prayed to God to bless the wind and rain.

King Yue was originally an ordinary thing for His Majesty.

At this time, there is something different in the officialdom.

Several officials gathered together to talk about the day.

"Have you all heard? Today's spring ploughing is in charge of the ear, is Yue Wangtai. ”

"Shouldn't this bull-eared person be the prince?"

"You haven't heard of it, have you? Our prince was lame, and he went to catch a crocodile a few days ago, but he was bitten by a crocodile, and his life and death are unknown. ”

"The news from the palace is said to have woken up, but the hands and feet are broken, and it can't be healed."

"It seems that this Datang is about to change the prince!"

"Your Majesty has already made up your mind."

"How can an incomplete person sit as the prince of a country?"

“……”

Everyone has discussed that Datang is still very enlightened now, at least there is no such thing as 'not discussing state affairs' in a certain era.

The lower-level officials are all talking about it, and the color of the emperor's can make them guess for a long time, not to mention that it was Li Tai who led the cow this morning.

Many people already believe that Li Chengqian is about to be deposed and Li Tai will become the new prince.

Most people also think like this, after all, Li Chengqian is lame, and now I heard that he has broken his leg, how can a prince who has no feet be a prince?

Some people are already ready to move, I heard that His Royal Highness the King of Yue likes beautiful daughters, and some officials are already preparing to send their daughters to the Yue Palace.

If he has no daughter, he will find a niece, and if he has no niece, he will find a maiden of the clan.

If it really doesn't work, just recognize a promising woman as a goddaughter.

Li Tai didn't know about the things outside.

At home, I slept until the sun was high, and then I got up slowly, then after eating, I turned on the computer, searched for the design drawings of plows, hoes, shovels and other agricultural tools in later generations, and then drew according to the drawings.

As I painted, I always felt that this picture was ugly, and it was hundreds of miles away from the computer screen.

Even the straight line Li Tai can't draw well, let alone the curve, it seems that this drawing is easy to say, but when I got started, I suddenly found that it was the same thing as I thought.

It's easy to think, but it's hard to draw!

"Xiao Yan Wan, you should help me draw." Li Tai looked at the fat Jiangdong plow, and the whole person was helpless.

This is a Jiangdong plow, which is clearly a mutated big fat shrimp.

Xiao Yan Wan smiled slightly, took Li Tai's pen, and then slowly drew stroke by stroke, I have to say that this Yan family is indeed very talented in painting, although Xiao Yan Wan is not very old, but she has already practiced good calligraphy and painting, which makes Li Tai ashamed.

Finally, after a while, Xiao Yan Wan drew Jiangdong plows, shovels and other things on paper.

Li Taile took Xiao Yan Wan into the palace.

And at this time, Li Shimin was already waiting for Li Tai in the Qinzheng Palace.

"Daddy, look what I got you." Li Tai walked in, couldn't wait to spread out the white paper in his hand, and then handed it to Li Shimin.

Li Shimin picked it up and looked at it.

Then, I couldn't help but sigh.

"Daddy, what's wrong? This is not appropriate? Li Tai asked, this is a very advanced thing, okay?

"It's suitable, but it's not suitable." Li Shimin shook his head, sighed, and said, "Qingque, your thing is good, but this thing is either copper or iron, hey!" ”

"This ...... What's going on? Li Tai asked puzzledly, "This is just some iron tools." ”

"Rich people can naturally afford it, but ordinary people don't even have a penny at home, how can they afford to use such a valuable thing?" Li Shimin sighed and said, "Things are good, it's a pity, it's a pity!" ”

it!

Li Tai couldn't help but scold in his heart.

What is possible?

This is known as the richest Tang Dynasty in ancient times, and the people can't even afford to raise a piece of copper and iron? I wanted to get some steel!

Li Tai seems to have forgotten that the poor people can't even afford a piece of clothing to cover their shame, where can they afford these farm tools?

Although the smelting technology of this era was very high, iron tools were not so easy to smelt, let alone steel.

Datang lacks iron, it really lacks it.

Therefore, there are more utensils in this era, or bronze vessels.

Therefore, the ploughshare alone weighs more than ten catties, which is more than two dollars and more than two thousand Kaiyuan Tongbao.

As for other shovels and the like, they will definitely not be low.

This makes Li Shimin very embarrassed!

Datang, it's still too poor.

"Do you know how many catties of pig iron Datang produces in a year?" Li Shimin asked.

"How much?" Li Tai was very curious.

"More than 10 million catties."

"Isn't that a lot?" Li Tai couldn't help but say: "With so much iron, it is more than enough to make ironware." ”

"Do you know how much of this more than 10 million catties can really be used?"

"How much?"

"Less than a million pounds!" Li Shimin sighed and said: "If it is divided into counties, armies, and ordinary people, it is less than 10,000 catties." ”

"Dad, you didn't lie to me, did you?" Li Tai was suddenly taken aback.

I'll go, what a waste of resources do you guys have to have?

No, you're not wasting resources, you're throwing them away!

The utilization rate of this iron is too low, right?

"If there was enough iron, I would have formed an iron cavalry and swept all directions!" When Li Shimin said this, it was really domineering.

"Daddy, you...... You really didn't lie to me? Li Tai couldn't help asking, this is impossible, are you kidding, Dad?

"Hmph, this is a matter related to the livelihood of the people in the world, how can it be child's play." Li Shimin glared at a pair of tiger eyes and said, "If there is enough usable iron, how can I be deceived by those Turkic cavalry!" ”

"Actually...... Actually, I seem to have a way. Li Tai said weakly.

The utilization rate of iron ore in this era was not high, mainly because the fire was not hot enough, and there was no way to fully fuse the iron ore with some minerals or shoot out some minerals out of the iron, and the iron produced was either very broken and easy to break, or it was too soft to be used.

If this problem can be solved, then the utilization rate of iron ore can be reduced.

"What can you do?" Li Shimin looked at Li Tai, shook his head, obviously didn't believe Li Tai, and said: "Since ancient times, except for those swordsmiths who can make good iron, ordinary people can't use iron at all, even those people in the royal family can't make good iron, what can you do?" ”

"This thing is dead, people are alive, can a living person be suffocated by urine?" Li Tai pouted, he really has a way.
