Li Ang browsed through the information in the memory hall in his mind and continued: "General, have you ever seen anyone who can't eat salt for a long time?"

"Of course I have."

Yan Yundang vaguely guessed what Li Ang was going to say, and nodded: "If you don't eat salt for a long time, your limbs will become weak, your face will look pale, and you will suffer from nausea and vomiting.

No matter how strong a man is, he will become so weak if he doesn't eat salt for a year and a half that he can't mount a horse or lift a knife."

"That's exactly the truth."

Li Ang said: "People must obtain different types of nutrients from food and water every day in order to maintain internal balance.

Once you eat less or cannot eat, you will become weak or even sick."

"Is it balancing yin, yang and five elements, qi, blood and body fluids?"

Yan Lin nodded. As a Xiantian realm warrior, General You Jinwu, he grew up in the army.

What Li Ang said has some similarities with the body refining methods taught in the military, but it is not difficult to understand - in the early stages of body refining, you also need to reuse prescriptions and take medicinal baths.

"Can..."

Yan Lin frowned and said: "The dishes my father eats are all normal, with a balance of meat and vegetables.

During this period, under the doctor’s advice, I stopped drinking alcohol.”

"The food is normal, but the problem with the Duke is in his stomach."

Li Ang said helplessly.

There are two possibilities for Yan Yundang's megaloblastic anemia. One is the lack of folic acid - vitamin b9.

The second is a lack of vitamin b12.

The daily requirement of folic acid is 200 to 400 μg. The human body stores enough folic acid for four months. As long as you consume fresh vegetables every day (overcooking or pickling vegetables will cause the loss of folic acid), there will be no problem.

Vitamin b12, synthesized by natural microorganisms, is the only vitamin that requires the help of an intestinal secretion to be absorbed.

Its storage capacity in the human body is about 2 to 5 mg, and the daily requirement is only 0.5 to 1 μg, and it can be absorbed repeatedly.

Even if you are a vegetarian who does not eat meat, it will take at least 10 to 15 years to develop vitamin B12 deficiency.

Yan Yundang is not a vegetarian or only eats non-vegetarian food.

His recipe is normal,

In other words, regardless of whether his megaloblastic anemia is caused by a lack of vitamin b9 or a lack of vitamin b12 (these two causes can only be identified through blood tests, etc., and there is currently no condition),

There must be problems with his gastrointestinal absorption function!

If there is insufficient folic acid, it means that the intestinal disease affects the absorption of folic acid.

If there is insufficient vitamin B12, it means a lack of intrinsic factor in the gastrointestinal tract, leading to vitamin B12 absorption disorder.

"Suppose a person has something wrong with his body and cannot maintain homeostasis no matter how much salt he eats, then he will become irreversibly weak."

Li Ang said: "Similarly, Duke Yan has a gastrointestinal problem. No matter how balanced he eats, his qi and blood will still become insufficient."

"The triple burner is the path of water and valley, and the place where Qi ends and begins. Does the lower burner need to reduce turbidity, and the middle burner needs to be activated?"

Qiu Zhen on the side murmured to himself.

The lower burner and middle burner he mentioned refers to the "Huangdi Neijing·Lingshu", the chest and abdomen are divided into three areas: upper burner, middle burner, and lower burner. The upper burner above the diaphragm is the upper burner, the stomach is the middle burner, and the lower burner is below the stomach.

.

Li Ang nodded, "Exactly."

"Then what can Dr. Li do?"

Yan Lin pursed her lips tightly, bowed her hands respectfully, and asked seriously.

"The way...it's hard to say."

Li Ang took a deep breath and said slowly: "The temporary solution is to eat more cooked and not overcooked livestock offal, eggs, fish, pears, and various vegetables including Langqiong Zhaobaleng.

Beef, pork, chicken, tofu, etc.

However, the probability that it will eventually be alleviated or even cured is only about 30% to 40%.”

Yan Lin was choked when he heard this, clenched his fists subconsciously, and said in a deep voice: "Why is it only 30%?"

"Gastrointestinal diseases cannot be accumulated in a day or a month."

Li Ang said: "Once the disease becomes diseased, it is extremely difficult to cure."

"Okay Lin'er,"

Yan Yundang interrupted his son who was about to ask more questions, and said slowly: "I, Yan Yundang, have been on the battlefield for more than fifty years.

When I was hungry, I gnawed on rotten horse carcasses, drank mire sewage, and even ate Guanyin soil and even the flesh and blood of demons.

Being able to live to the age of seventy is already a blessing from Haotian.

For organ lesions, 30% is enough to hope for cure.”

He stared at Li Ang deeply and asked: "Doctor Li, if this anemia disease is not cured for a long time, what will happen to me in the end?"

"...pernicious anemia will not directly cause death in the short to medium term,

But if it doesn’t get better, you may continue to have fatigue, drowsiness, numbness in your hands and feet, and jaundice.”

Li Ang whispered: "In the most serious case, it may lead to mental depression or even...insanity."

"Insanity?"

Yan Yun hesitated and then raised his head, a strange smile appeared on his face, "Hahaha, when I was young, my fellow soldiers would always laugh at me as 'Martial Madman', 'Martial Madman',

I never thought that they would all die of old age or in battle, and I would really turn into a lunatic..."

"Father!"

Yan Lin's eyes were red and she choked, but she was greeted by Yan Yundang's stern eyes, "Stand still! What does it look like for a man to cry!"

Yan Lin subconsciously raised her chest and raised her head, standing upright, with the outline of her clenched jaw appearing on her cheeks.

Just like when I was young.

Yan Yundang pursed his lips slightly with mixed emotions, stared at Li Ang and said, "I'd better thank Dr. Li.

At least let me know why I will die."

Li Ang cupped his hands and stopped talking.

In fact, the 30% chance of cure he mentioned is basically folic acid deficiency, which can be alleviated by supplementing large amounts of folic acid.

If Yan Yundang suffers from pernicious anemia due to gastric mucosal atrophy and lack of intrinsic factor in the gastric juice, resulting in vitamin B12 malabsorption...

Then there is absolutely nothing you can do.

Vitamin b12 is a red compound containing cobalt. Its atomic structure is extremely complex, with 181 atoms distributed in a magic felt shape in space.

If you want to artificially synthesize vitamin B12, you need to synthesize the various parts of vitamin B12 first, and then connect them together.

Under the current conditions, it is simply impossible to achieve it.

"Yan Jiu, please go to the warehouse and then deliver it to Dr. Li for me."

Yan Yundang let out a long sigh and raised his hand to ask the old servant butler, who was also choking, to send Li Ang out on his behalf.

The old housekeeper first went to the warehouse, then returned to the hall, and took Li Ang to the side door of the backyard. Qiu Zhen also accompanied him.

When he reached the door, the old housekeeper suddenly stood still and bowed deeply to Li Ang, "Thank you so much, Dr. Li."

"where..."

Li Ang sighed softly, returned the gift, and said hesitantly: "If the Duke's Palace wants to use pigeons to conduct experiments according to my method, it might as well set up a few more groups and feed them bran bark, bran bark mixed with a small amount of sugar, and a small amount of bran bark mixed with a small amount of sugar.

Salt chaff, only feed sugar, etc.

Wait until some pigeons become unwell before feeding them brown rice.

Use this to test whether my statement is correct or not.

As for the Duke's condition, I will go back and check the medical books and think of a solution."

"Thank you, Dr. Li."

The old butler nodded gratefully, took out five Qianguan flying tickets from Liuguang Bank from his arms, and was about to hand them to Li Ang.

"What are you doing, old man?"

Li Ang refused to accept it, but the old housekeeper said: "This is the wish of the Duke, Li Xiaolang, just accept it.

The notice posted by the Duke's Office in Chang'an already stated that any medicine prescribed by a doctor that can alleviate the disease will be rewarded with thousands of dollars.

If I can be cured, I will be rewarded five thousand guan."

After repeated refusals to no avail, Li Ang could only accept a Thousand-Guan flight ticket in the name of relieving his symptoms, got on the vehicle of the Duke's Mansion, and returned to Huaidefang.

————

It was late at night, Li Ang was lying on the bed in the bedroom, looking at the starry sky outside the screen window, his lips slightly pursed.

In the evening, the servants of Duke Yan's Mansion came again and brought over the bay-red horse that had been fostered in the pasture of the academy.
