－－－－

Ping Yi frowned and couldn't tell her mood. She saw her sharp eyes sweep back and forth on Li Yan several times before snorting: "Before taking your medical skills, I will tell you about medical ethics..."

Medical ethics? When Li Yan heard this, he was shocked. You are a famous doctor who killed someone, right? You actually talked about medical ethics to me? I don’t listen to your medical ethics.

He only heard Ping Yi's finger and said: "Medical skills are a very particular science. Even if a doctor prescribes medicines right ten thousand times, he may kill a patient if he accidentally makes mistakes once... Doctors are actually a kind of butcher. There is no absolute boundary between treating people and killing people..."

Li Yan was very angry and thought to himself: If this guy is going to talk about it, this guy will soon talk about her perverted theories that doctors must kill one person.

However, Ping Yizhi did not talk about her theory, but said seriously: "Therefore, a doctor must first be able to recognize medicine. All medicines and herbs must be extremely accurate in identifying everything. If you make a mistake in one herb, it may kill a person's life. The first question I gave you is to identify herbs... You wait, I will go and get herbs."

Speaking of this, her body flashed and disappeared.

Li Yan was surprised: Ping Yizhi's attainment in light skills is very high, no worse than Teacher Fan Song's.

After a while, the figure flashed again, and Ping Yixing reappeared in front of Li Yan. This time she was carrying a big vine basket, filled with various colorful herbs. When she saw it, she was afraid that there were no less than a few hundred kinds.

She threw the basket in front of Li Yan and hummed, "Take out the herbs inside and say their names and effects in turn. If you say the wrong one, even if you fail the exam."

"Wow!" The teachers next to him made a big noise. The royal sister teacher, the great god and demon Fan Song, couldn't help but say: "Teacher Ping, what Li Yan wants to take is only the third grade of elementary school. Is it necessary to have such high requirements? Generally speaking, if there is a 60-tenth degree, he can pass the test, as long as he can say 60% of the medicinal materials, it's fine."

Ping Yi pointed and snorted coldly, "You big-breasted and powerful woman know nothing!"

The teacher Yujie said furiously: "Who is the big-breasted monster? Do you, the old-fashioned virgin, want to fight me alone?"

Ping Yi pointed and snorted coldly, "I ask you, one day you were seriously injured. A doctor prescribed medicine for you, but only 60% of the medicines prescribed were correct. Another 40% of the wrong medicines were prescribed incorrectly. Can you still survive?"

Teacher Yujie thought for a while and said, "Of course I can't live."

Ping Yi pointed and sneered, "Well, that's it? The saying that medical skills are not passed or failed is only absolute right and wrong. If you are right, treat people, and if you are wrong, kill people. So I don't allow Li Yan to admit his mistakes. If you are a big-breasted monster, don't interrupt me if you don't understand."

The teacher Yujie was defeated, as Ping Yizhi said, medical skills are not comparable to other subjects, and there is no mistake at all. There can be flaws in martial arts moves, and hidden weapons are allowed to fail to hit the enemy. These small mistakes can be made up with other moves, but the doctor prescribes medicine but cannot tolerate any mistakes. If you get a mistake, you cannot get a disease. She was convinced, but she was very upset at Ping Yizhi's "big-breasted monster girl" who scolded her, and waved her fists and said, "Old virgin, wait for me, and you must look good."

The two teachers quarreled here, and the students in the audience were naturally talking. Someone stood on Li Yan's side and whispered: "Teacher Ping Yizhi has also been too strict. If you are a medical student in high school or university, you will naturally not be able to make the same mistakes. But you don't have to be so strict in the third grade of elementary school. It's not that you really have to prescribe medicine. What's the point of admitting the mistakes? There is still a lot of time to study in the future, so there is no need to get stuck like this."

The girl with pigtails said with a gaze: "It should be like this. It's difficult. No matter how difficult it is, he won't be able to get the exam. Hahahaha... His 300,000 taels belong to me."

People around him were talking, but Li Yan's face remained unchanged. He took a deep breath, first closed his eyes and meditated on what he had learned in the past month. Hu Qingniu, a doctor in Butterfly Valley, taught him for a month, and he had learned a lot of various herbs, because the medical skills of Butterfly Valley's medical immortal are not worse than those of the famous doctor in Butterfly Valley. The medicinal materials in Butterfly Valley are also as high as mountains. Li Yan spent a month studying hard and mixing with these medicinal materials every day. Why are you afraid of at this time?

He reached into the vine basket, grabbed a medicinal herb, looked carefully, and said, "This is Angelica, also known as Gangui. It is born in the valley of Sichuan and has a sweet taste and is warm. It is responsible for coughing, reversing the upper qi, warming malaria, cold and heat, and women leaking the child, causing all evil ulcers, and metal stimulation. Boil and drink it."

Ping Yiqi nodded with Hu Qingniu, obviously he was right.

Li Yan grabbed another medicinal herb and said, "This is lily of the valley, bitter, warm, and toxic. Using it as a medicine can strengthen the heart and diuresis. Using it as a poison can cause flushing on the enemy's face, nervousness and irritability, headache, hallucination, erythema, dilated pupils, vomiting, stomachache, nausea, slowing heartbeat, heart failure, coma, and death."

Ping Yiqi and Hu Qingniu nodded again.

Next, Li Yan was able to tell the story as he caught and told him. He recognized each medicinal material clearly. In a blink of an eye, hundreds of medicinal materials passed, and he had not said it wrongly.

Hu Qingniu had known this result for a long time, smiling without saying a word, his face was full of lust. He was obviously happy that he had such a student. Ping Yiqi's face remained unchanged, but he couldn't help but secretly praise him: This child is indeed amazing. He has only been able to recognize so many herbs in just a month, which is indeed amazing.

After a while, all the medicinal materials in the vine basket brought by Ping Yizhi were taken out. Li Yan actually recognized more than 200 medicinal materials, and he said nothing wrong. In fact, Ping Yizhi was not a crazy teacher. The more than 200 medicines she brought were considered common medicinal materials. She did not use those strange and strange medicines that were difficult to find for a hundred years to deliberately make things difficult for Li Yan.

The teachers and classmates on the Taiwan side were moved, and several teachers couldn't help but say, "Just relying on this skill of medicine, it should be fine to go to the third grade of elementary school, right?"

Some students were wailing: "It's over, our bet...we will definitely lose."

The most unlucky one among them is Wei Xiaobao, a girl with a braid. Every time Li Yan talks about a medicinal material, her body shook. By the time Li Yan has finished all the medicinal materials, the braided girl is already a little shaky and can't stand steadily. Her eyes are constantly turning around, thinking: After all, I will pay 3 million taels? Where can I get 3 million taels? This time... I really want to sell myself. I dress up, but I don't know how much it can be sold... It shouldn't be worth 3 million taels, right? The courtesan in Yangzhou is said to be able to make the rich young man spend ten thousand golds. I sell my body according to the courtesan standard. Even if ten thousand golds are good, ten thousand taels of gold equals 10,000 taels of silver, and what should I do if there are two million taels of silver? (Note: In ancient my country, one tael of gold was converted into ten taels of silver.)

Amid the wailing sound, everyone thought that Li Yan must have passed this time, but Ping snorted coldly and said, "Don't be anxious! Just knowing how to recognize medicine is not qualified to skip the grade... I have to ask the second question to test his ability to get medicine." She said seriously: "The medical skills of the third grade of elementary school require at least being able to be a pharmacy mate, and the thing that pharmacy mates do the most is to get medicine according to the prescription."

Ping Yi pointed and said, "I have a few prescriptions here. Li Yan, please take them out according to the order. Remember, you must do not have more or less when grabbing medicine. Just right, if you ask you to grab one or two angelica, you cannot grab nine coins. If you ask you to grab one pound of ginseng, you cannot grab one pound of 1 ounce of 1 ounce of 1 ounce of 1 ounce of 1 ounce of 1 ounce of 1 ounce of 1 ounce of 1 ounce of 1 ounce of 1 ounce of 1 ounce of 1 ounce of 1 ounce of 1 ounce of 1 ounce of 1 ounce of 1 ounce of 1 ounce of 1 ounce of 1 ounce of 1 ounce of 1 ounce of 1 ounce. You must know the severity of the medicine. You must not get a 5 ounce of 1 ounce of 1 ounce of 1 ounce of 1 ounce of 1 ounce. "

Speaking of this, Ping Yi waved his hand, and two prescriptions flew out from his sleeve, which said how much does a certain medicine cost and how many taels of a certain medicine. She added: "I allow you to weigh it with a scale."

Hearing Ping Yizhi's words, the onlookers and students started to make noise again: "This is too strict, right? How can you be so accurate? Why are you allowed to use a scale? This is not accurate to use a scale."

It turns out that ancient scales were all very old-fashioned scales with very limited accuracy. It is not a problem to use them to weigh pounds, but it is not possible to be accurate to a few dollars. One more and one less when grabbing medicine depends entirely on the experience of doctors. Famous doctors are extremely accurate in taking medicine, while quack doctors often catch mistakes. In theory, the third grade of elementary school exams should not be so strict, and it is inevitable that one or two dollars will be wrong. However, a flat finger is old-fashioned and you must be stern in everything you do. She insists on setting such strict requirements, and no one else can do anything.

Teacher Yujie waved her fist and said furiously: "Old virgin, are you deliberately making things difficult for the students in my class?"

Ping Yiqi said with a straight face: "I don't have time to make things difficult for anyone, I just respect medical ethics."

The students were also lively. The girl with pigtails in the crowd jumped up and down with joy and said loudly: "Yes, it's so strict. If you make a mistake, he will fail. He will keep him at the same level. Hahahaha... His 300,000 taels are mine."

Li Yan smiled bitterly at her and sighed: "Mistress of pigtails, you can't be so unfaithful for betting. We are friends at least. Do you want me to reconcile the grade?"

The girl with pigtails laughed and said, "I have been reincarnated. How can you be considered loyal if you don't reincarnate? For the sake of loyalty, you should also reincarnate with me."

"Damn it!" Li Yan rolled his eyes at her: "You are unkind and I am unrighteous. It seems that I have to do something wrong."

The teachers and classmates were surprised: "You have any tricks? What tricks do you have to accurately get money when grabbing medicine?"

Li Yan calmly reached into his arms and took out a lot of things, a shelf, a lever, two pallets, and a pile of copper ingots. Each copper ingot was marked with a number, including one, five, ten, twenty, fifty, one hundred, etc.

Ping Yiqi couldn't help asking, "What is this?"

Li Yan smiled and said, "Well, it's called a weight balance scale. I plan to use this thing to weigh medicine."

It turned out that during the month he was studying medicine, Li Yan had been confused about the amount of medicine taken by ancient doctors. He saw that Hu Qingniu was based on experience and grabbed the medicine casually. He said that how much money was just a few. Although he was indeed very accurate in taking medicine, it was absolutely impossible for ordinary doctors to do it. This does not conform to the concept of later generations. Later generations should never make medicine based on experience. All materials must be accurate to one gram or two grams based on scientific formulas, and liquid medicine must even be accurate to milliliters.

In order to solve the problem of inaccurate medicine, he went to the Qing Palace with a teleportation wall half a month ago. Since Wei Xiaobao had helped him get an imperial kitchen in the Qing Palace, he was considered a person with status and status. He used his identity to find Johnson Chan, who served as the Imperial Heaven Prison in the Qing Dynasty (note, Johnson Chan was an Italian, a Jesuit missionary, priest, and scholar. He lived in the Qing Dynasty for forty-seven years, and went through two dynasties in the Ming and Qing Dynasties. He made a statement in the 34th chapter of the Deer and the Cauldron). He asked him to find Western craftsmen to help him create a Western balance scale, a pile of copper weights, so that the weight of the medicinal materials can be accurately weighed.
