Bai Ling stood up almost immediately in shock, "He's locked up?" ”

"No, it's not......," Bai Shijun patted his daughter's arm soothingly, "It's him who wants to tinker with something behind closed doors, and we cleaned up the firewood room in the west together yesterday so that he can tinker alone." ”

Bai Ling had a false alarm, and then he realized that if Bai Yi was really locked up by Jinyiwei, it was unlikely that his father would be able to write at his desk as usual.

"Would you like to go to your brother's?" Bai Shijun asked.

Bai Ling stroked his heart and shook his head slightly, "Then there's no hurry...... Since he's busy, let's keep him busy first, and I'm not going to bother. ”

Bai Ling's gaze fell on Bai Shijun's desk, where there were many sheets of paper spread out and full of words, each loose paper with a date and a note in a red pen.

"Dad was just repairing a book?" Bai Ling stepped closer and bent down to look.

"Hmm." Bai Shijun stroked his beard and sighed with a smile, "I've been stuck in this place in front of me for a long time, and I don't have a clue today." ”

Bai Ling carefully pulled out a piece of paper from the table and looked at it carefully, judging from the date, it should be a manuscript left by his father five years ago, recording the increase and decrease of the medication he gave to a child in Qingyang for five days, and the course of the child's illness in those five days—this is one of the few children who has saved a life from the mouth of the epidemic.

Every piece of paper here is such a case.

Bai Shijun's words are concise, but the details are very detailed, on the one hand, because he has been writing hard all these years, and he has a rare pen power in the choice of words and sentences.

On the other hand, because he almost never saves what he should have done today until the next day, he writes every piece of first-hand information here in the night of the day.

No matter how big or small the details are, whenever he thinks of hearing and seeing, Bai Shijun will write them all down, and then make a choice when he sorts them out afterwards.

So every case in the manuscript retains the most vivid details.

In the past, neither she nor Bai Yi cared about what Bai Shijun was doing, which may be the instinctive arrogance of all traversers.

In a world where the sky is round, where bacteria and viruses are unknown, where there are no antibiotics, no human cognition based on anatomical experiments, and even the most people do not have even the most ordinary common sense of hygiene, it is difficult for medicine to bring any cure in the face of vicious diseases.

The average life expectancy of an entire society is less than 30 years old, which is the best interpretation of the medical level here.

Where there is a miracle doctor who can cure the disease, where there is any ancient secret home remedies, in the face of modern medicine, all homeopathic treatments are vulnerable.

Before the emergence of the technological revolution of mankind, eternity was like a long night.

She and Bai Yi are both people who have lived in the light before, and because they have seen the light, they can never go back to the darkness.

"Where are you stuck?" Bai Ling asked seriously, "Can Dad talk to me?" ”

Bai Shijun sighed, "Actually, I discussed with Bai Yi a few days ago, and none of these treatments have been treated with 'control variables', so now I can't tell which key variable is working." ”

Bai Ling was stunned.

"Control...... Variables. ”

She was a little unaccustomed to hearing such words from her father's mouth.

Bai Shijun nodded, and continued, "Bai Yi said that when increasing or decreasing the dosage, at least one 'control group' should be set up, so that we can know whether the herbs are working. But there are also many problems with this, one is that people send their children here to treat diseases, not to let you test medicines, so it is immoral to use them as a comparison;

"Besides, each child's physique is different, and it is useless for you to control the increase or decrease of the dosage of a medicine......

Bai Ling listened carefully to what Bai Shijun said, and it could be seen that Bai Yi and Bai Shijun had a lot of discussions together in the past few days.

Bai Ling suddenly remembered that when Bai Yi entered the palace the day before yesterday, he said that if his father's book could be handed down, he would probably be the pioneer of ancient evidence-based medicine.

Now it seems that this is true, because although Bai Shijun did not conduct any subjective controlled experiments, but because of his detailed case descriptions and detailed comparisons, he can actually reflect the simple "evidence-based thinking".

In other words, medicine is not a philosophical or witchcraft or other mystical miscellaneous, and all treatment decisions should be based on empirical evidence based on clinical research.

But there are no microscopes, no separators, no petri dishes......

Bai Shijun's question is destined to wait hundreds of years before human beings can give an answer.

Looking at his father's solemn expression, Bai Ling smiled, "Actually, I feel that the problem of the controlled experiment is not completely unsolvable?" ”

"Huh?" Bai Shijun raised his head.

Bai Ling scratched his head, a little uncertain, "For example...... Try experimenting on animals first? ”

Bai Shijun immediately put on an expression of "not feasible".

"Bai Yi thought of going with you, saying that he could try mice and rabbits." When Bai Shijun said this, he shook his head again and again, "How can this work, people have twelve meridians, five internal organs, how can rabbits and mice be compared with people, no, no, no!" ”

Bai Ling smiled, the genetic sequence of the mouse is extremely similar to that of humans, and it is susceptible to various diseases, and it reproduces quickly and cheaply, and it is easy to feed...... It's a natural laboratory animal.

But for a while, she couldn't explain this to her father.

Bai Ling got up with a smile and walked out, "Dad, you should be busy first, I'll go to Bai Yi and talk for a while." ”

Bai Shijun waved his hand and laughed as he listened to Bai Ling's departing footsteps.

This girl, just now said that since Bai Yi is busy, she won't bother.

He also got up and sat back at the table, continuing to worry about the case at the table.

Think again......

Bai Shijun sighed, even if he couldn't find cause and effect, he would think of a way to sort out a context of these things.

The firewood room in the northwest corner of the hospital is the most remote place in the entire hospital.

All the offices of the Tai Yi are concentrated in the front and middle courtyards, and the northeast corner is the most lively - there is a gathering place for most of the Tai Hospital's apprentices, where all the Chinese medicine is boiled, and it is done by the apprentices who have just started and the experienced doctors are watching.

So as soon as he walked to the backyard, Bai Ling asked about a sky-high smell of medicine, but this smell was not pungent, and it was not difficult to endure it once he got used to it.

In order to prevent fire, the firewood room is far away from the fire room, and there are more than a dozen firewood rooms in the northwest corner, generally half of which is firewood, and the other half is empty, in case of emergency.

On weekdays, except for some people who carry firewood and decoction medicine, the firewood room in the northwest corner is almost empty.

But today, this place can probably only be described as "heavily guarded".
