Li Yuanji did not stipulate it according to the unified standards of later generations, because it was unnecessary and unscientific.

Again, there is no comparison between the two at all.

Later generations casually pulled out a person to check the body, most of the elements in the body are actually not lacking, even if they are missing, there are only a limited few, and most of the reasons for this are caused by partial eating, most of which are mainly children.

Of course, this refers to those in normal areas, and poor areas such as mountainous areas cannot be compared.

And in the era of Datang, if you pull out a person at will, and if you don't lack a few elements on your body, you will lose.

The situation of the royal family and nobles will be much better, because they have no shortage of food and clothing, and they have enough strength to eat more nutritious food.

But it is difficult for ordinary people to do this, even if the life of Datang is much better than before, and the people are very satisfied, but in fact, from the perspective of nutrition, the entire Datang is still in the stage of 'the sick man of East Asia'.

The people are not short of food, which means that there is rice to eat in every rice bowl, and most of this rice is rice or noodles, in addition, vegetables are only a small amount, and they rely on digging in summer and life in winter.

Therefore, according to the standards of later generations, each person is only allowed to donate blood once in half a year, because according to the living standards of later generations, half a year is enough time for them to make up for the lost blood.

But now, just look at Qin Qiong and Zhang Gongjin.

These two are not rich enough to rival the country, at least they are also rich and jade, even in winter, they can often eat all kinds of green vegetables or something.

Especially Qin Qiong, when the vegetables in the greenhouse had not appeared before, whether it was Li Yuan or Li Shimin, they often asked people to send some vegetables to Qin Qiong, but even so, after so many years, the blood lost in Qin Qiong's body still has not been completely replenished.

Therefore, if you can draw less than 300 milliliters of blood at most in five years, it may not be safe under the current conditions.

And this incident once again touched Li Yuanji's heart.

He also wanted to engage in a vegetable basket project like later generations.

But after thinking about it, I felt that it was a little inappropriate, poverty limited people's abilities, and it also limited Li Yuanji's hands-on ability.

Although the situation in Datang is improving, the speed of improvement is also limited, and it is impossible to accumulate to the point where there is too much money to spend in just a few years.

"Vegetable basket project?" The ministers looked confused, when did the cabinet meeting become so down-to-earth?

"Yes!" Li Yuanji nodded affirmatively.

Although it is not suitable, it does not mean that it will never be suitable, take advantage of the time when it is not suitable, plan in advance, make some preparations that can be made, and then wait until the right time, you can quickly promote it.

It's like an army, you can practice more in peacetime, and when there is a war, you can directly pull it up to fight without having to sharpen your guns.

"Your Majesty wants to promote greenhouses on a large scale?" Ma Zhou's eyes lit up, and he saw hope in an instant, but then he fell into disappointment, and couldn't help but shake his head and said: "But the experience of the greenhouse is not suitable at the moment, first, the cost is too expensive, and second, the scope of customers is too narrow, if it is promoted on a large scale, the people are afraid that they will lose their money." ”

"Well, that's the reason!" Cheng Zhijie nodded his head seriously, he agreed with what Ma Zhou said.

Who doesn't know how many greenhouses they have made at home? Who doesn't know that he was almost killed because of these greenhouses? Almost bankrupt?

Even a big guy like Cheng Zhijie can't be lowered, let alone those people?

Although the price of vegetables in the current winter is cheaper than before, many rich people can eat it every once in a while, but this price is still too expensive, even those big dogs, it is impossible to eat every day, eat every meal, if you really want to do this, you can eat countless families in one winter.

In the final analysis, the reason for this is that the cost of the greenhouse is too expensive, to be precise, the price of glass is too expensive, this thing is good, but the average person can't accept it.

And greenhouse vegetables want to be accepted by more people, then the only result is that the price drops, can be expensive, the price of selling is twice as much as in summer, three times is not a problem, even if not everyone can accept it, at least most people will accept it, but the problem is that the price cannot be lowered at all, unless the price of glass drops significantly.

"And this thing is also inconvenient to transport, even if it is transported within a state, even if it is just picked, it is basically impossible to wait until it arrives at the place, wait, the transportation ......" Fang Xuanling said and said, suddenly stunned.

The most inconvenient is transportation, and the cost of transportation is huge, manpower, animal power, these all cost money, even now there is an official road from Chang'an to Luozhou, which can greatly improve transportation efficiency and reduce transportation costs, but this cost is still very high, it can only be said that it is lower than before.

So what if you use a train?

Tyrannical creatures......

"The problem is, but that is not the most important, any problem can be tried to solve, before there was no cement official road, everyone felt that the distance was too far, and it was not easy to walk, so we built a cement official road, the seven-day journey was reduced to five days, one way to save two days, not to mention how much cost can be saved in these two days, if it is non-stop back and forth, it is this year's time, you can run more than 20 times before.

Although this was already very convenient, I still felt that it was too slow, so I ordered the Academy of Sciences to start studying trains, and now the results you have seen are that the efficiency of transportation has increased exponentially, but the cost has decreased exponentially.

Therefore, I feel that the last thing Datang is afraid of is the emergence of problems, and the most feared thing is that problems arise, but we have no way to deal with them. Li Yuanji said slowly.

After all, they are not people who have grown up in the context of the new era, and their thinking has been solidified over the years.

In the past few years, the change is changing, but this change is very limited, and it is impossible to completely change their thinking, but some ways of dealing with problems must be changed.

All in all, Li Yuanji wants to establish a core idea for these ministers to be officials, boldly conceive, and carefully verify it.

If you can't even think about it, what else can you do?

"This thing can not be done overnight, the financial resources of the imperial court are not allowed for the time being, and the cost of glass is difficult to drop significantly, in addition to the constraints of raw materials, the output has also fallen into a bottleneck period, but as long as you are willing to study, you will find a way after all." Li Yuanji continued.

"This ......," the ministers scratched their heads and expressed helplessness.

It's not that they don't want to delve into it, it's that they really can't think of a better way.

One is transportation, the other is cost, these two difficulties completely limit their imagination, can't they build trains to every county, right? It is the Changluo Railway, which makes the ministers have a headache and can't do it, and this is still the most cost-effective way to do it.

"Using the channel of the supervisor's desk, I used a year to understand the environmental changes and the growth of plants in the entire Datang county. Each supervisor is in charge of a county, and in addition to his own feelings, he is required to find no less than 100 people in each area of the county to inquire about the climate change situation for the whole year, and finally summarize an average and summarize it into a book. Li Yuanji didn't care what these ministers thought, and he couldn't care about it, anyway, he already had a preliminary plan for the specific operation.

Statistics on the climate of each county, this thing is not difficult, mainly time-consuming, but for supervisors, it is nothing more than an additional statistical task when inspecting, and this is also very consistent with their work, because supervisors are to visit everywhere, all year round are constantly running around, to understand the people's feelings, to understand the official voice, and the climate problem, Lala often knows.

But this is not the only way to know the climate, but only as an auxiliary means of understanding, so that when a new species arrives, it can be quickly deduced which areas are suitable for the growth of this plant.

"Second, the caravan leading to the Western Regions region should bring back all kinds of specialties in the Western Regions, I refer to all kinds of seedlings, seeds, etc., and record the growth environment of this species in detail, so that after bringing it back to the Tang Dynasty, it can be quickly placed in a suitable area for planting, so as to enrich the people's rice bowls."

"Third, start training a large number of ocean-going sailors immediately, and when the problem of steam-powered ships is solved, they will start sailing." Li Yuanji finally stated his purpose.

And the so-called ocean, in fact, is to aim at North and South America, what does North and South America mean now? Corn? Potato? These eats?

No, wealth, endless wealth.

The strength of any country cannot avoid the plundering of other countries, at this time, North and South America are almost uncivilized regions, Li Yuanji has no reason to doubt that even if Datang transports a few boatloads of garbage, it can bring back a shipload of gold and silver.

Money is a good thing, no one doesn't like it, Li Yuanji also likes it very much, and none of the powerful countries in later generations didn't start by sailing.

Wang Xuance's Eastern Expeditionary Army, was it only used to fight Japan?

Fighting Japan is just military training, and the real purpose is the endless sea, which does not pose any threat to the Tang Dynasty at all.

"I don't believe that there is no other land beyond the vast sea, and the benefits of trade are well known to everyone, so I don't need to say more." Speaking of which, Li Yuanji pulled the topic back and returned to the so-called vegetable basket project again: "Rich species are the foundation that supports the prosperity of the Tang Dynasty, and the ultimate goal of my decision is to let the people of the Tang Dynasty have the food they want to eat at any time in the vegetable basket." ”
