Everything about the West, Fang Ce did not take it to heart.

Everything is handed over to Luo Cheng, and he will act on the opportunity.

So Fang Ce was very relieved, at this time, Di Renjie had already begun to study some things that appeared in Detective Conan.

Especially a thing called fingerprints, he is particularly attentive.

Been working on this thing.

Because as long as you master this thing, basically many cases will become simpler.

Many times, criminals leave fingerprints.

And it's very easy to study this thing.

Because Fang Ce has already made a telescope, he can even use a telescope to observe the sky.

Therefore, at this time, Di Renjie, as long as he makes good use of the principle of the telescope, he can study something that can observe fingerprints and then make judgments.

Fang Ce didn't bother Di Renjie either.

It's a bit hard, but it's still a simple version.

Because some criminals don't know what their psychology is, they always like to make a bloody handprint before committing a crime to show their identity.

With this bloody handprint, you can lock this guy before this murderer commits the crime.

When the time comes, just take someone and arrest it.

So these things are still relatively simple.

Di Renjie began to study these things.

However, at this time, Sun Simiao also began to slowly recover.

The poison was too deep before, and he already understood something after Fang Ce's on-demand.

And what Fang Ce said is very right, and he can do hemp boiling.

And the long-lost hemp boiling has a perfect recipe in Fang Ce's book.

For a divine doctor of Sun Simiao's level, with good medicinal materials, it is very simple to improve an existing formula.

However, Sun Simiao is accustomed to using gold needles for anesthesia, and this kind of drug anesthesia is also a challenge for him.

But without a challenge, there's no point in it.

Sun Simiao is happy to accept the challenge.

This Huaxia Academy can be regarded as peaceful and quiet, but Chang'an at this time is not too peaceful.

The long-missing King of Wei returned to Chang'an.

was personally received by Li Shimin, after all, this child has not been seen for a long time.

Although this child is a bit rebellious, when he comes back at this time, he is still a good boy.

When he heard Li Tai's statement, he said that there was a kind of car that could carry thousands of people from one place to another place quickly, as long as a very special road was built.

When Li Shimin heard the news, his eyes immediately widened.

It's just a clapper.

Promised Li Tai.

What is the reason?

Isn't this march all about speed?

Thousands of people can quickly travel to another place at a time, and if it is ten times, isn't it tens of thousands?

Isn't that what you want in a marching war?

That's a huge invention!

And listening to Li Tai's tone, this is something he has come up with, and when he heard it, Fang Ce didn't adopt it.

Li Shimin immediately breathed a sigh of relief.

This Fang Ce is still too young.

Don't use such a good thing?

I really don't know what to say!

He is an emperor, and he still knows a lot about military and political affairs.

That's what he wants.

Li Tai can also be regarded as his favorite, and Li Shimin directly made the decision.

The rest of the work can begin.

As a first step, Li Tai decided to build a railway from Chang'an to Luoyang.

It was the first railroad he wanted to build.

It started with the simplest step.

At this time, Li Shimin didn't know what kind of setbacks were facing him.

Fang Ce didn't want to spend money indiscriminately, and Li Shimin didn't know how much he was going to spend.

Of course, Li Tai didn't say how much it would cost.

Because he doesn't know either, he is so focused on research that he doesn't care about anything outside his body.

He just wants his invention to be realized, so he doesn't care about how much money he has.

After arranging the work, let the work begin.

To make these things, how many things to buy, are verified by the people of the Ministry of Industry.

At this time, the Ministry of Industry was cooperated by a person named Yan Liben.

At this time, Yan Liben was still a middle-aged man, and he was also a celebrity in front of Li Shimin.

A master of painting.

When he received Li Tai's painting, he didn't dare to compliment.

But looking at the contents of the picture, he carefully calculated the cost.

One rail, one meter and sixty pounds of steel.

When he saw this data, Yan Liben's heart suddenly clenched.

This Nima!

How far is Luoyang to Chang'an?

Not far away, only 380 miles.

That's 190,000 meters.

Two rails are 380,000 meters.

If it is calculated as weight, it is more than 20 million catties.

Yan Liben was speechless for a moment.

More than 20 million catties of steel!

How much does it cost?

This is simply a cheat!

At this time, Yan Liben directly ran over to find Li Shimin.

"Your Majesty, this train can't be done!"

Yan Liben cried bitterly directly, and knelt in front of Li Shimin and cried.

Li Shimin was also confused, and he didn't know which play Yan Liben was singing.

"Yan Aiqing, you say, why is this?"

"Your Majesty, this Luoyang to Chang'an, according to the description of the King of Wei, this Chang'an to Luoyang to build a railway, back and forth, four steel rails, a total of 45 million catties of steel! It's appalling! It's just Chang'an to Luoyang! If it is connected to Gangnam, it is an astronomical amount! ”

Yan Liben directly told Li Shimin a number.

Li Shimin was directly trembling.

This Nima is too terrifying, isn't it?

Forty-five million catties?

Even if you melt the weapons of the whole world, it won't be enough.

And that's just what needs to be consumed between Chang'an and Luoyang.

If there were more, how much would it be?

Li Shimin rolled his eyes, and now he finally understood why Fang Ce didn't give Li Tai a chance.

With all the strength of the whole country, it is estimated that it can only be a little distance, if the entire Tang Dynasty is around, how much steel will it take?

Completely confused.

Li Shimin didn't dare to think about it anymore.

"Call this rebel to Lao Tzu!"

Li Shimin gave an order directly to Gonggong Miao next to him.

Father-in-law Miao also went to call Li Tai very quickly.

Li Shimin said to Yan Liben: "Aiqing, please get up, this time, it is your credit, I almost became a sinner, this road must not be built!" ”

Li Shimin is not a monarch who wants to save face and suffer crimes, so after he realized his mistake, he decisively stopped.

There is no need to worry about this.

He doesn't fool around.

Soon Li Tai was called over.

"Qingque, let me ask you a question, do you know how much steel is needed to build a railway from Chang'an to Luoyang?"

Li Shimin wanted to know if Li Tai knew about this.

Let's find out what he's all about.

"I know! Four steel rails, a total of more than 40 million catties, this should not be a lot. ”

Li Tai's face didn't matter, he didn't know the price at all, he only knew that he needed so much steel.

According to his father's ability, such a thing should be very simple for him to get it.

Li Shimin looked at Li Tai's breezy face, and suddenly became furious!

"Rebel!"

Li Shimin almost yelled out, and scolded Li Tai.

completely gave up his imperial prestige, and rushed directly to Li Tai and beat him violently.
