    ??????????????? ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

    Tie Heng was thinking about something in his mind, but he always paid attention to the changes in the medicinal materials in the alchemy furnace in front of him.  At this moment, wisps of white smoke came out of a circle of small ventilation holes on the stove lid, and it became thicker and thicker. Tie Heng knew it was time to add the last few ingredients.

    Refining elixirs generally uses cauldrons or alchemy furnaces of various sizes. The former are mostly used to make ointments, which makes it easier to observe the changes in the medicine with your eyes.  The latter is refining pill powder, most of which need to be sealed and simmered, and the lid cannot be opened easily. They can only rely on the smell overflowing from the ventilation holes on the furnace cover and the color and density of the smoke to judge. Among them, the former  This is particularly important, which is why Liu Jiaoyu said that qualified pharmacists have a nose with a sensitive sense of smell.

    "Tie Heng, why don't you add the ingredients?" Tang Tang had already opened the stove lid and put the several ingredients he had prepared into it one after another. He stirred it carefully twice and hurriedly closed it again.  She turned around and found Tie Heng sitting still, so she couldn't help but remind him anxiously.

    "No hurry!" Tie Heng replied with a smile.

    He is not in a hurry, but Tang Tang is worried.  Everyone was refining Qingjing Powder, and the time for each stage was almost the same. Seeing other students around them completing this step, only Tie Heng did not move. When the little girl was worried, she couldn't help but be curious, because Tie Heng often  Give her an unexpected surprise.

    "What are you going to do?" Tang Tang couldn't help but ask him.

    "You'll know later." Tie Heng blinked his right eye at her and said mysteriously.

    "Oh!" Tang Tang is not the kind of girl who likes to ask questions. After hearing what Tie Heng said, she stopped asking questions and just watched curiously and obediently.

    "Tangtang!" Lu Shan on the other side called her softly, and the girl turned around.  "What tricks is he doing again?"

    "I don't know either, he refused to say." Tang Tang also lowered his voice.

    "Hmph! He has the most weird ideas. I don't know what weird things he will make!" Lu Shan said disdainfully, but in fact, she was just as curious as her friend.  After spending time with Tie Heng, Lu Shan was unknowingly attracted by some of his whimsical ideas, and her attention to him increased day by day.

    "Do you still remember the Bingliang Wan last time? He actually wanted to change the taste, and the resulting Bingliang Wan was honey-sweet and introduced all kinds of bugs from the yard into the classroom. The teacher actually praised him for doing a good job  , saying that this new military food pill is suitable for trapping spirit insect demons. Huh! He is obviously doing something crazy" Lu Shan looked very angry, but she looked at Tang Tang next to her.  Have fun "Pfft".

    "Sister Lu, are you very unconvinced?" Tang Tang asked quietly.

    "Not convinced?" Lu Shan was stunned for a moment, but she quickly came to her senses.  "No? Who wants to be dissatisfied with him? I'm not that boring. I'm just I'm just"

    Lu Shan could no longer speak under the gaze of her friend's clear eyes. In the end, she could only glare at Tang Tang, turned her face away angrily, and stopped making any excuses.

    Tang Tang covered his mouth and laughed for a while.  Turning back, she looked at Tie Heng worriedly and prayed secretly.  "It doesn't matter what you do, just don't invite so many bugs in again."

    Since the beginning of the school year, as time goes by, basic courses have gradually begun to deepen, and many subjects have carried out practical courses.  Among them, the alchemy course is the one that requires the most hands-on experience and accumulation of experience.  Because he was only performing some simple refining work, Liu Jiaoyu did not arrange for students to go to the special alchemy room in the school, but taught everyone in the school.  More than a month ago, something happened when Tie Heng was refining the primary elixir Bingliang Pills.  Bingliang Pill is not so much a medicine as it is a kind of food.  A grain as big as a soybean can keep the eater from feeling hungry for half a day without eating.  But that time, Tie Heng changed the formula after successfully refining a few soldier grain pills. He used some cheap raw materials on hand to mix a pill that exuded a sweet and fragrant smell. As a result, the courtyard around the school was ready to hibernate.  All the insects that had spent the winter were lured out, causing a lot of trouble.

    Tie Heng here is naturally unaware of the worries of the two girls on the side. He is staring at the alchemy furnace in front of him with all his concentration.

    "The heat is almost done." The best time to add the subsequent raw materials has long passed, but Tie Heng is not anxious at all. What he wants is more heat in the medicine.

    In his hand, there are several raw materials that have been cut, mashed, juiced, ground, etc., and they can barely be distinguished as some plants, the scent glands of certain animals, and a few small amounts of ore debris.

    Seeing that the time was right, Tie Heng picked up the furnace cover with one hand, opened a gap, and moved his fingers with the other hand.He quickly put several raw materials into the furnace in the predetermined order, then gently mixed them with the stirring rod, and then closed the lid again. The whole process only took a dozen breaths, and the next step was to continue.  Wait patiently.

    Liu Jiaoyu had another chance to talk, but the students could only listen silently and pretend to listen carefully. It was definitely hard work.  Tie Heng couldn't help but think that after Liu Jiaoyu's teaching method of fatigue bombardment, it was hard to say anything else, but his ability to resist interference when refining alchemy must be much stronger than others.

    About half a quarter of an hour later, the refining of Qingjing Powder has reached the final step of refining spiritual power.  Tie Heng was later than the others in the previous stage, so he was naturally the last one to put the magic formula into the alchemy furnace.

    When he opened the stove lid and scooped the frost-like medicinal powder inside into a small porcelain box, many students were already holding their own refined medicines for Liu Jiaoyu to taste and grade, and they lined up in a long line in the aisle.  .

    "There are too many impurities. I'll give you a middle-range one. You can take care of yourself in the future, but you can't be careless anymore. Do you understand?" Liu Jiaoyu returned the small porcelain box in his hand to Luo Yao and scolded him sternly.

    "Understood, sir." Luo Yao secretly took a bite. Just now he saw Liu Jiaoyu's frown, and he was worried that he would only get an inferior price.

    "Next." Liu Jiaoyu stopped paying attention to him and called Luo Ming behind him. He took the small porcelain box handed to him with both hands. After opening it, he gently fanned his nose twice with one hand.  It was cold and freezing, and the windows in the classroom were closed tightly, so the room was filled with various smells, including the smoke of charcoal fire, the aroma of herbs, and the weird smell of other raw materials.  Liu Jiaoyu was actually able to judge the quality of the students' works in such an environment without even lighting the powder. His sense of smell was indeed astonishingly sharp.

    "It's quite pure, the proportions of the various raw materials are well controlled, and the heat is acceptable. It's just that the final refining was a little too hasty, and the efficacy of the medicine was somewhat affected, and the spices you chose were not fully exerted." Liu Jiao  Yu took a deep breath, shook his head and said, "You can get a good grade. If you pay more attention, your grades can go to a higher level."

    "Yes, sir, students will definitely work hard in the future." After getting a good score, Luo Ming answered loudly and happily.

    The next few students received different evaluations. Two of them failed to refine and turned into waste after one furnace, so they could only receive inferior evaluations.  None of the others got the distinction, until it was Lu Shan and Tang Tang's turn.

    "You two girls, give it to me together!" Lu Shan and Tang Tang performed well in every class and were naturally loved by all the gentlemen, including Liu Jiaoyu.  He knew that the two girls were good friends, so he deliberately tasted their works at the same time so as to compare them.

    "Hmm!" Liu Jiaoyu just sniffed it lightly and then made a long nasal sound, obviously in admiration.  "Not bad, very good. You two are very good."

    He praised them several times, then took out a handful of medicinal powder from each of the two small porcelain boxes, observed and smelled them in front of his eyes.  After a while, two wisps of flame suddenly rose on Liu Jiaoyu's palm, and the medicinal powder slowly melted, exuding a similar but distinctive fragrance, which soon filled the classroom, and many students were taking deep breaths.  , and then let out a long sigh of relief.

    "The purity is very good, which shows that the two of you have handled the selection of raw materials, processing and subsequent steps very well. Even a formal pharmacist can only do this." Liu Jiaoyu continued to comment.  road.

    "What's even better is the spices you each selected. One of the main ingredients is the saliva of the tapestry bird, and the other uses the heart of the red wain wood. Haha, it seems that you all have family backgrounds. Some of the gentlemen are like me.  I don¡¯t know the secret recipe! Well, the ingredients are just right. The former can relieve inner worries, and the latter can make people recover from mental fatigue. Wonderful, really wonderful! "

    Qingjing Powder is a first-grade yellow grade incense used for meditation. Its function is to enhance people's sense of smell, and its fragrance can relax the body and mind, calm the blood and eliminate distracting thoughts. It can effectively improve the user's concentration during meditation.  And his perception of the spiritual energy of heaven and earth is more keen.  Generally speaking, pharmacists will add some additional spices during refining according to personal preferences to achieve better results.  Take the works of two girls as an example. Eliminating worries and restoring mental fatigue are special effects that other people¡¯s Qingjing Powder does not have.

    Lu Shan and Tang Tang looked at each other, seeing surprise on each other's faces.  They didn't expect Liu Jiaoyu's nose to be so powerful. He could distinguish the characteristics of their respective works in such a messy smell environment after only smelling such a small amount of smell. This surprised them.

    "I will give each of you a first class." Liu Jiaoyu said with a smile, and then with a stroke of his pen,Mark down the results for the two girls in the comment book.

    "Thank you, sir." The two girls thanked him handsomely.

    "Don't let down your guard in the future. Your qualifications are far superior to those of ordinary people. Sir, I am very optimistic about your future achievements. If there is a senior pharmacist among you, sir, I will be considered a successor. Maybe I can even borrow your skills."  "Guang, leave your name in the history books!" Liu Jiaoyu joked brightly, and then turned to other students.  "Don't look at Qing Jing Powder, which is sold everywhere in the market. You can buy a small pack for four or five silver dollars. It seems very inconspicuous, but it is the basis of all incense elixirs, including those high-end meditation incense.  It is developed from it. If you want to achieve something in the future, you need to study these basic knowledge carefully at this moment, but don't let this great time go by."

    The students all said they would keep it in mind, but they didn¡¯t really listen to it, and only they knew it.  However, when Liu Jiaoyu saw the serious expressions of Lu Shan and Tang Tang, he couldn't help but feel that he had not wasted his words.
