Ma Zhou, who was like a madman, ran to the palace with disheveled clothes and a disheveled face dancing with joy.

The black circles under his eyes indicate that he doesn't seem to be getting a good rest, but compared to the results, Ma Zhou obviously attaches more importance to the latter, this is a research discovery that can benefit Datang and all mankind, how can it not be ecstatic?

"After many arguments, I found that what you said is indeed right, Your Highness, the difference in food can indeed cause the appearance of night blindness." Ma Zhou forced himself to calm down, but he couldn't calm down, so he could only continue to talk with a wild dance.

"How do you argue?" Li Yuanji pretended to be surprised.

I could have come up with a mature answer to solve this problem, but that would only bring more trouble to myself, and it would not be conducive to subsequent arrangements.

A seemingly simple argumentation process can actually pry the entire Datang and guide Datang in the right direction, even if it can't, you can arrange it according to your expectations.

I don't want to be an emperor, I don't want to live that kind of 'hard life', but I don't dare to guarantee my son, and my grandson doesn't want to live that kind of 'hard life'.

Therefore, the only thing I can do is to help them pave the whole way, and if they have that kind of idea and talent in the future, I don't mind sending them to the throne, or leaving them a foundation enough to ascend to the throne.

It is better to teach people to fish than to teach them to fish, this is what Li Yuanji thinks at the moment, this is not to make a dowry for others, but to forbear, but to accumulate strength.

The small one visited more than 4,000 people in various places, including government soldiers, people from Chang'an City, people outside the city, fishermen by the river, hunters in the mountains, and butchers in the city, and finally found only more than 200 people who had no night blindness or only had mild night blindness.

Among the more than 200 people, the people of Chang'an and the surrounding people are mainly suffering from mild night blindness, and the situation of some government soldiers is somewhat special, they have nothing to do for a period of time after receiving the conscription, but with the increase of the time of the expedition, night blindness will begin to appear gradually, and then return home to recuperate for a few months, and the night blindness will disappear.

Fishermen and hunters, on the other hand, have little to do with it, and these two groups of people account for more than a hundred people.

Upon inquiry, Xiao found some things in common, such as fishermen often eat fish, but they don't dare to guarantee that they will have enough to eat, so they like to cook a pot of soup and eat it with meat. Hunters often eat their prey, as well as some green vegetables found occasionally, and butchers often eat some pigs under the water. That is to say, all of these people's food is related to meat, and those who suffer from night blindness have little contact with these meats, and soldiers rarely come into contact with these during the war, and they are often exposed to these after returning home, so the small ones think that eating meat can solve the problem of night blindness. Ma Zhou said with an affirmative face.

Visiting more than 4,000 people overnight, he alone can't complete it, but there is a bug in the construction site, and it is not a problem to investigate 4,000 people overnight.

"The preliminary answer is yes, but this matter is very important, and it can even affect the future of Datang, so you can't be careless, so your conclusion is too rough, and there is a lack of actual evidence to prove your results." Li Yuanji shook his head, since he did it, then he should be perfect, or as close to perfection as possible, and be perfect under the existing conditions.

What Ma Zhou really did was just investigate according to his own reminders, in other words, it is like a doctor who surveyed 100 patients with painful cancer, and found that there was a certain food in their diet, so he directly issued a conclusion, saying that this food is the root cause of cancer.

Such a conclusion simply does not hold water, because there is a lack of actual scientific evidence.

Science is still too far away for this era, but experiments are necessary and necessary, no matter how nice they say, people are just listening, but if you put direct evidence in front of them, everyone will be convinced of your answer.

Demonstrating night blindness is a large topic, and the scope involved is even more unimaginable, and it is impossible to complete such a large experiment in a few months without the knowledge in your own head as a foreshadowing.

"All of this we do is ultimately for the sake of people, but what people eat, you can't make changes without evidence, remember, in order to convince people of your answer, you must put out enough evidence, just like a case, there is no direct evidence to prove that someone is a murderer, then you can't be convicted." Li Yuanji patiently explained, deeply imprinting the word rigorous into Ma Zhou's thoughts.

"The little one knows it's wrong!" was preached by Li Yuanji, Ma Zhou's excited enthusiasm was extinguished in an instant, and he lowered his head like a chicken in soup and admitted his mistake.

"In this way, you will take people outside the city to buy a batch of game and fish during this time, and if you want to collect a batch of pigs, we will also collect a batch, let's prepare first." Li Yuanji continued to instruct, do experiments, how can you do it without goods in your hands?

"Your Highness, this ......" Ma Zhou hesitated slightly, and then looked in the direction where the East Palace was located.

"If anyone asks, say that this king plans to open a garden of ten thousand beasts." Li Yuanji said angrily, you TM buy food, not people, right? Or do you all think the king is stupid enough to rebel against these animals?

"No!" Ma Zhou nodded, and then planned to leave.

"Oh! By the way, to publicize it to the outside world, this king intends to open a Konashi on the first day of the next month, and all the elders who have a skill, regardless of age, whether they are literate or not, can come to sign up for the event, and there is no charge for any fees. Li Yuanji shouted Ma Zhou, and took advantage of the procurement to do publicity at the same time, which can be regarded as saving some money.

"No!"

In the blink of an eye, everyone was busy, and the most idle was only Li Yuanji, and the bored Li Yuanji had to run to his new palace to direct the craftsmen to decorate, anyway, there was only one request, luxurious to burst, comfortable to death, whether lying or standing, giving people only one feeling, that is, cool.

……

Unlike Li Yuanji's leisure, the interior of the East Palace was busy, the Turks finally withdrew their troops, and the threat of Chang'an was lifted, which should be a day of great joy.

But where the Turks in the north passed, there was no grass everywhere, and the loss of people and property was countless, and what was even more tragic was that the imperial court had no money to go to disaster relief.

Li Shimin wanted to suppress the family, but found that at this time, he had to ask for help from the family, except for the family, no one else could take out so much property to relieve the disaster, but if he opened his mouth, he would not be able to suppress the family in the future, which was a dilemma.

If there is only one thing that makes Li Shimin feel embarrassed, then it is enough, compared with the previous one, another thing is Li Shimin's biggest headache.

The Turks retreated, Li Yuanji was the first to make contributions, and Wei Chi Jingde followed closely behind, and he could not be rewarded for his merits, but the person who made meritorious service was Li Yuanji, the king of Qi, which made Li Shimin very painful.

But anyone who has a relationship with King Qi has a headache for Li Shimin.

If you don't reward it, people in the world will be panicked, which is not conducive to your own stable position.

reward, will elevate the identity of the king of Qi and threaten himself again.

At the beginning, Li Yuanji was asked to command the army, and even issued an edict, which was really helpless, and now when it comes to rewarding meritorious deeds, he is also helpless.

What to do?

Li Shimin once again realized the emperor's helplessness, and also realized why Li Yuan repeatedly broke his word to himself, and moved his whole body, full of helplessness.

"What do you think should be done with this matter?" Li Shimin, who had a headache, felt that there was no need to just have a headache for himself, so he threw the problem to a group of confidants and ministers.
