Ning Bei couldn't cry or laugh.

Although the audience asked him to unify the blue star at every turn, this is very scary.

No matter what dynasty it is placed in.

But if you think about it, you will see that what they said is not without reason.

In ancient times, if you want to reclaim a piece of wasteland, it will take at least a few years or even a dozen years to turn the wasteland into fertile land.

Moreover, ordinary people do not necessarily deal with wasteland, so it is necessary to find people who are specifically responsible for dealing with wasteland.

However, if there were so many talents in ancient times, there would not be so many hungry people.

Therefore, if you want to feed so many people in the Tang Dynasty, it is much more cost-effective to open up fertile land in foreign countries than open wasteland!

It's a good deal, both in terms of time and cost!

It is only necessary to capture foreign territories with elite troops.

If you don't come to the text, you will go directly to the martial arts.

Whether other dynasties have this strength, Ningbei does not dare to guarantee.

But he can guarantee that the Tang Dynasty will definitely have this strength!

After all, what Tang Taizong advocates is force!

As soon as the iron horse of the Tang Dynasty comes out, who dares to compete!

Directly unify the bein-Americas, what will happen to the beautiful country in the future?

This is called fundamentally solving the problem of the beautiful country and preventing it from doing evil in the future!

There is also Feizhou, according to expert investigations, the land of Feizhou is very fertile, except for those deserts, the rest of the land can be regarded as a real fertile field!

What is planted on these lands is highly profitable, and it is still three crops a year!

But because of the laziness of the people of Feizhou, they wasted such good land resources!

And the benefits of Uni-Unified Blue Star are not only these, not to mention the seasonings, all can be used.

The most important thing is that you can also get potatoes and sweet potatoes!

These two vegetables are the real weapons that can save people!

Potatoes and sweet potatoes can be eaten not only as vegetables, but also as staple foods.

Their yield is not generally high, potatoes can produce three or five thousand catties per acre, and sweet potatoes can produce six thousand catties per acre!

Even if the amount of potatoes and sweet potatoes produced in ancient times was not so much, it was definitely not comparable to the production of three or five hundred catties of grain per mu in the Tang Dynasty!

How many people have to be fed with so much food!

The reason why the Qing Dynasty was able to reach a population of hundreds of millions was because of potatoes and sweet potatoes!

If you can get these two vegetables, then the people of the world will not go hungry.

Ningbei is also a farmer, so naturally he will not make money from farmers with a clear conscience.

can feed the people of the world and make money, that is the most awesome businessman!

If you don't have any idea of the unified blue star, let's take an example.

During the first industrial revolution, the Eagle Nation seized the opportunity to colonize the territories of other dynasties, robbed them of their wealth, and forced them to help them grow food and produce materials for themselves.

There are traces of the colonization of the Eagle Country all over the world, and they are all colonies of the Eagle Country, so during that period, the Eagle Country was also called the 'Empire on which the Sun Never Sets', and it was the real overlord of the earth!

The ancestor of the beautiful country is actually the Eagle Country, but later...... Everyone is good on Baidu, and there is everything on Baidu.

And what is the origin of the two world-class wars for?

It's not about redistributing Blue Star resources!

The Eagle Nation occupies almost the world's wealth, so what will the other countries that have completed the Industrial Revolution eat?

In order to get the wealth and resources you want, then you can only fight!

The strong is king!

This is the law of nature that has been passed down since ancient times!

But if Ningbei or he let Tang Taizong unify Blue Star in advance, then what happened to the other powers?

With the advice of Ningbei, a traversing person, even if it is to let Tang Taizong completely annihilate these countries, it is not a difficult matter.

Of course, if you don't unify Blue Star, you still have to see what his identity is after crossing over.

If he Ningbei is just an ordinary person, then why do you worry so much?

Honestly choose a business and do it slowly.

Everything is difficult at the beginning, first stand firm and then talk.

Ning Bei wanted to stop the audience's brains, but when he saw that some stubborn viewers were talking about Quyuan plough and cylinder car, Ning Bei instinctively chose to shut up.

Let them talk!

No matter how big their brains are, they only need to choose skills that are realistic and beneficial to them.

Restricting the audience all the time may make them even more crazy......

People often like to do the opposite.

Ningbei silently wrote down the Quyuan plow and the cylinder car, these two treasures are definitely a weapon for opening up wasteland.

The emergence of the curved plough allows people to adjust shallow tillage and deep ploughing according to their needs, and the operation is flexible, which not only saves animal power, but also reduces the physical consumption of the plough farmers, and improves the efficiency of farming.

As for the cylinder wheel, it is shaped like a spinning wheel, which will rotate with the flow of water, drawing water from the river to a high place and pouring it into the aqueduct, saving time and effort.

Speaking of which, the tube car is also a fully automatic machine, and it does not require electricity.

The next fully automatic machine may be the steam engine.

However, the steam engine was invented in 1698, and the cylinder car appeared in the Sui and Tang dynasties, hundreds of years earlier than the steam engine!

I have to say that the wisdom of the ancestors is beyond imagination!

Modern technology can have such a thing, all of which are standing on the shoulders of giants and summing up experience.

If it weren't for the failures and successful progress of our predecessors again and again, we don't know what modern times would become.

Not to mention anything else, as long as Ningbei can make them, in a short time, the problem of farming will be solved.

Moreover, these two tools are also very conducive to the reclamation of wasteland.

At that time, even if he can't buy good land, he can still get a good harvest with these two sharp weapons.

Another point is that once these two tools are made, the people will not be so tired.

They can also find time to do it...... Other jobs can increase income anyway.

This is also for the benefit of the people.

After firewood and rice, there is oil and salt.

Regarding oil, the audience has already discussed it before.

The appearance of oil was very early, and China had a tradition of cooking with oil in the Zhou Dynasty.

The word 'paste' in the Zhou Dynasty is made of animal oil.

It's just that the method of making oil is too complicated, and the ancients didn't know how to preserve it, and it usually doesn't take more than a few days before they have to make a new one.

Therefore, in ancient times, only large families who were either rich or expensive could afford to use oil.

Although the Tang Dynasty was prosperous, ordinary people still couldn't afford edible oil.

Not only could they not afford it, but the porcelain pots they used were limited by the fact that the flame temperature was not enough during production, and they could not withstand too high temperatures.

Usually, there is no big problem with cooking some rice, but if you put oil, the porcelain pot may melt on the spot......

Until the time of the Song Dynasty...... That's right, it was still the Song Dynasty, the Song Dynasty when everything began to appear, that the people could afford to buy oil.

In addition, the iron smelting technology during the Song Dynasty has been greatly developed, and the people can afford to use iron pots for cooking.

Although everything started from the Song Dynasty, the dynasty that Ningbei crossed was not the Song Dynasty!

He also wanted to eat delicious stir-fried vegetables in the Tang Dynasty, instead of boiling them every day.

Therefore, Ningbei has to find a way to get oil.

Peanuts were introduced into the country in the Qing Dynasty, and this will be ignored for the time being, and we will talk about it when we have the opportunity in the future.

Sesame seeds were introduced to China from the Han Dynasty, and sesame oil appeared very early, but the price was too high and belonged to the nobility.

Therefore, it can be said that the production technology of sesame oil can be perfected, but Ningbei is not ready to do sesame oil business.
