"Your Majesty, Huang Ren and Ma Yuan's letter to you!"

"Well, put it on the table!"

After hearing Han Lucheng's voice, Li Yuanjia did not raise his head, but continued to draw the grid on the paper while saying something lightly.

"Yes, my lord."

Gently placing the letter on the table, Han Lucheng walked lightly to the door.

As the chief butler of the Han Wangfu, of course he won't take care of everything, in fact, trivial matters like receiving letters are usually directly given to Chunyan and Liu Mei. It's just that a few people's letters are exceptions, such as Li Zhong, Wang Pu and other directors of major workshops outside the city, such as Li Lingkui, the king of Yu, who is far away in Luzhou, and then Huang Ren and Ma Yuan, the two subordinates sent out, etc., these people's letters can only be taken over by Han Lucheng himself, and then personally delivered to Li Yuanjia's hands.

"By the way, wait a minute."

Just as Han Lucheng was about to walk out of the door of the study, Li Yuanjia suddenly remembered something, raised his head and shouted.

Han Lucheng naturally turned around quickly, walked to the desk and stood with his hands down: "King, what else do you command?" ”

"That Turkic merchant, did you ever return to Chang'an?"

"Back to the king, I haven't come back yet."

Hurriedly shaking his head, Han Lucheng replied cautiously: "But if you count the days, it should be soon, and they should be able to arrive in early May at the latest...... Lord, do we want to buy some specialties from the grassland? ”

After thinking for a while, Li Yuanjia shook his head and said, "There's no need to buy things, but when that Turkic merchant comes back, you immediately send someone to meet him and ask about spirits and tea...... Don't slack off, you know? ”

"Yes, King!"

"Hmmm......"

With a slight bow, Li Yuanjia originally wanted to send Han Lucheng out, but as soon as his hand was raised, he put it down again: "There is another thing, has the pork liver been sent out this decade?" ”

Pork liver?

After a pause, Han Lucheng figured out what Li Yuanjia was asking, and quickly shook his head and said, "Back to the king, not yet." But tomorrow is the day, and I have ordered someone to book it with the great butcher in the city, and I will send someone to fetch it early tomorrow morning, and then send it to them as soon as possible. ”

"Very good, don't forget!"

Hearing this, he nodded with satisfaction, Li Yuanjia smiled and said: "And you must remember that at the end of each month, you will send someone to ask everyone carefully to see if their night blindness has improved, and you must not forget!" ”

The use of pig liver to treat night blindness is an attempt by Li Yuanjia.

There are many causes of night blindness, but in this day and age, most of them are caused by vitamin deficiencies, that is, temporary night blindness. Only this kind of night blindness Li Yuanjia has the confidence to try, other such as congenital or acquired night blindness, often need to be treated for the cause, then Li Yuanjia is really helpless.

He had never seen this kind of disease in his previous life, so naturally it was impossible to treat it.

Therefore, the only way to spend money is to buy pork liver and give it to people who can't see at night to eat and try it. And the last time Han Lucheng was statistical, it was two months after those night blindness ate pork liver in a row.

I don't know if it's because there is too much time, or if the intake and absorption are not enough, the effect is not particularly obvious. But according to most people, it's definitely better than before!

Such a result naturally gave Li Yuanjia a lot of confidence.

Anyway, the pork liver in this year is not worth much, so Li Yuanjia ordered Han Lucheng to insist on sending three pieces a month to each person to observe the effect for a long time......

Han Lucheng naturally knew this, and immediately nodded and said, "Yes, king!" I have taken this to heart, and I will never forget it. ”

"Alright, you go down first!"

This time, Li Yuanjia didn't stay with Han Lucheng anymore, and waved his hand to let him out.

Just when the housekeeper slowed down and was ready to stop him at any time, Li Yuanjia had already begun to open Huang Ren's letter.

Don't think about it, it's definitely the return data.

So Li Yuanjia was very happy when he opened the letter, because as Huang Ren and Ma Yuan became more and more skilled and experienced, the proportion of wounded soldiers who died or became disabled due to infection became less and less - in the absence of antibiotics and modern medical conditions, it is impossible to save all of them, and Li Yuanjia's goal is to increase it to more than eighty percent!

The only pity is that the sample size is too small and the time of the trial is too short.

In particular, the previous trials were almost all done in winter, and the cold weather can suppress the possibility of bacterial infection, so the rate of cure will definitely be higher. But as the weather gets hotter and midsummer is approaching, Huang Ren and they will soon ...... No, I'm afraid they're already facing a serious challenge right now!

But anyway, it must be much stronger than before, right?

"What if...... Now it's good that there's a war! ”

Thinking about it, Li Yuanjia naturally had a thought in his heart: "It's best to have a big battle of tens of thousands of people, the kind that can hurt hundreds of people a day, and then let Huang Ren and them organize a group of people to serve in the army...... That's the really big sample size, and it's the most convincing. ”

When pondering these things in his heart, Li Yuanjia's heart was as calm as water.

A little cold-blooded, but he couldn't control himself.

Even in Europe, where modern medicine originated, surgeons were treated as vassals of internal medicine physicians until the 20th century, and were despised for an unknown number of years. It was not until the sterilization and counting, anesthesia, blood grouping, and blood transfusion techniques were gradually perfected that they gradually got rid of the bottom of the chain of contempt, and finally became an existence alongside internal medicine physicians.

Li Yuanjia knows very well in his heart that the most important thing is the effect!

Just like traditional Chinese medicine, the status of ancient times was supreme, from the Han Dynasty to the Tang Dynasty, but step by step fell into the mortal world, and was finally included in the list of "technicians", why? Isn't it because there are very few diseases that can be cured by traditional medicine? Even they had to resort to the art of forbidden spells, and set up the position of forbidden spell master in the Imperial Doctor's Department?

So the only solution is to let them see the results!

Being able to save people is fundamental!

Therefore, Li Yuanjia's first thought was war, because only war is the best technical catalyst, so that the whole court and the central government can pay attention to the debridement and suture technique he took out!

Because of excessive blood loss, shock and other factors on the battlefield, it is impossible to save everyone with this method, but as long as Huang Ren and the others can carefully clean the wounds of the soldiers, wrap the wounds with sterile bags or even clean gauze, and keep the wounded barracks clean and tidy, Li Yuanjia is sure that they will definitely be able to create a miracle on the battlefield!

Why can't Nightingale do what they can?

"Hoo ......"

Thinking about it, Li Yuanjia felt that he couldn't continue to think about it. After shaking his head and taking a long breath, he refocused his attention on the letter written by Huang Ren in his hand.

This time they followed the emperor to Jiucheng Palace, what did they gain?
