If all this is true, Datang will usher in an unparalleled prosperous era, which can almost create a foundation for eternity.

Well, of course, this is just Li Shimin's idea.

If it were Li Su, of course he wouldn't think so.

It is far from enough to solve the problem of food and clothing for the people.

The irrational system and science and technology must also be developed at the same time.

If not, when the West sets off a technological upsurge, and they are stagnant, they will be beaten sooner or later.

But for Li Shimin and the ministers, the status of these three crops in their minds is too important!

This feat can be said to be chasing the three emperors and five emperors!

And the yield of these three crops is still only hearsay.

Although the ministers felt in their hearts that this number, even if it was inflated, it would not be too much.

Otherwise, it would not have solved the problem of food shortage because of these three new crops, plus fishing, and made the five surnames and seven hopes suffer heavy losses.

However, until they saw it with their own eyes, until it was fully confirmed, they were still in disbelief.

However, these three crops, especially sweet potatoes, are drought-tolerant and high-yielding, that's for sure.

The top priority now is to ask the king of Shu, where is this sweet potato suitable for planting, and it is serious to promote it as soon as possible.

And once the yield of these three crops is really confirmed, then the hero of Shu must be rewarded.

……

After sowing winter wheat, before you know it, winter has arrived.

Perhaps because of the drought, the cold air came later this winter.

In winter, ordinary people are idle and have nothing to do.

At most, they will go to the mountains to collect some firewood, make straw sandals and other trivial work.

But this year is different, and you can go to build railways this year.

Now the business of Yizhou Zhonghua Commercial Bank is getting bigger and bigger, and it is really not bad for money.

The construction of the railway is now being carried out in sections.

From Yizhou to Chang'an, many construction starts along the way.

As long as the people want to come to work, except for the first ten days of the apprenticeship, which is five cents a day, the next ten days are ten cents a day.

It is also full of three meals a day, and meat is eaten every day.

On the construction site, I work for about five hours a day.

It can be said that there is such a high wage as ten cents, even if you are only full of three meals a day, there will be a lot of laborers who come to work.

You know, if you can have a winter of chewing left, that's also a sum of food.

Not to mention, on the construction site, eating better and more than they can eat at home.

Don't you see those people who work on the construction site all year round, most of them, are fat!

The food is so good, it would be strange if it wasn't fat.

In the past, due to financial problems, there were not so many workers recruited on the construction site.

And now, because of the abundant funds, it is the people who do not refuse, and the more the merrier.

With the influx of a large number of workers, the speed of railway construction has also been greatly increased.

After another two months, just when there was still a month to celebrate the New Year, the railway was finally completed!

After the completion of the whole site, Li Su tested it through the system, found out a few defects, and ordered someone to rectify it, and then it could be put into use.

In the following time, the eyes of countless people were focused on the railway.

They all wanted to see what kind of car the Metropolitan Governor would come up with to run on this railway.

Can you still pull thousands of people at a time, or hundreds of thousands of catties of goods, as the Metropolitan Governor said?

I'm afraid I'm not bragging, right?

Don't talk about those civil and military ministers, don't talk about those people.

Even in Yizhou City, the people of Yizhou, who worship the King of Shu as a god, are a little skeptical.

On the contrary, several of Li Su's apprentices, as well as Wu Meiniang, Li Yuanfang and others, believe that he will be able to do it.

In the next time, Li Su ordered people to cover a large area on the side of the Yizhou Railway.

Prepare to lift the train crew onto the tracks.

In reality, of course, there is no need for people to carry it, and the train is not made in advance, which is just a way to hide people's ears.

In the evening, Li Su ordered martial law and entered the platform of Yizhou alone.

Then in the mall, a locomotive was purchased, as well as ten passenger cars and ten wagon cars.

After purchasing these, there is not much left, but there is still a little left.

After thinking about it, Li Su came directly to the edge of Baihua Pond and used the remaining points to buy a few sets of amusement facilities.

Of course, I think that there is no electricity yet, and these entertainment facilities can be controlled by manpower.

The most important thing about these recreational facilities is the guarantee of safety.

And just after Li Su finished buying the amusement facilities, he got a system prompt:

Ding, because the host loser value consumes more than one million loser value, and the system is currently being upgraded.

With that, the system suddenly went dark.

Li Su contacted the system again and found that he couldn't be contacted.

……

On the second day, Li Su first found someone to settle the amusement facilities.

Then he came to the platform of Yizhou Railway Station, and removed the covered tarpaulin, revealing the locomotive inside, ten passenger cars and ten freight cars.

Seeing such a behemoth, the onlookers, the guards and others were all shocked beyond measure.

Even those disciples of Li Su, as well as Shangguan Yi and others, are no exception.

In fact, the size of this train is completely beyond their imagination.

Such a large behemoth, capable of carrying thousands of people and pulling hundreds of thousands of catties of goods, seems to be able to do it.

But how can such a big behemoth run?

Well, what Li Su exchanged this time was a steam locomotive that had been eliminated in later generations.

Commonly used in later generations, there are electric locomotives and fuel locomotives.

However, these two types of locomotives, one uses electricity and the other uses fuel.

Under the current conditions, there is no way to use it.

Therefore, Li Su can only exchange for a steam locomotive.

It's just that the speed of this steam locomotive is not slow at all.

The locomotive exchanged by Li Su is among the best in terms of speed among steam locomotives.

The maximum speed can reach 200 km/h. (The UK's fastest steam locomotive, the Inspiration, can reach up to 322 km/h)

And the speed of 200 kilometers per hour, in this era, is already flying fast.

If it is not a full load, from Yizhou to Chang'an, it will take about three hours.

In one day, you can go from Chang'an to Yizhou and make a round trip.

This steam locomotive, Li Su decided to name it Pioneer.

Recently, it was the day of the Pioneer sea trial.

The first sea trial, of course, was operated by Li Su himself.

However, as the Metropolitan Governor, of course, he can't do it himself every time, so he deliberately selected a group of students to learn train driving skills.
