The carriage prepared by the royal family took us to the mansion of the Knight of the Kingâs guard, whom the king asked me to treat yesterday.
âGood morning Luke! Iâll be counting on you again today!â
âGood morning.â
Zeno-san was there when I got off the carriageâŠthe king himself welcomes me?
ââȘ Heâs worried about his friends. Also, before masterâs mind changes, itâs the highest priority for the country to learn how to treat labor cough, so it is also an important job for the king to come and ask for help.â
âHe doesnât want to leave it to someone else and put me in a bad mood? It seems like there are people out there who wouldnât want to get involved with me because of my bad reputation.â*
ââȘ Thatâs right. In fact, thatâs very likely. Master is the âOrc Princeâ who is notorious even in neighboring countries. Itâs no wonder Zeno is cautious and moved on his own. â
By the way, Navi is waiting in the subspace.
Hati and Diana are being taken care of by Mifa and Emilia. Navi, who observed Dianaâs behavior all day yesterday, decided that there was enough common sense to let her do as she pleases. From now on, Diana will be allowed to do what she wants to some extent.
When I said that I would hold a recovery magic seminar today, Diana seemed to be more interested in the âSummoning Ceremonyâ and chose to watch it. It doesnât seem fun to come to a seminar. Besides, I didnât really want to bring my servants here because today we have a gathering of potentially infected labor cough patients. I donât think itâs something that can be passed to a god beast or a dragon species, but I didnât feel like bringing them here.
âLuke, you told me that you could treat as many people as I wanted, so today Iâm bringing 15 labor cough patients to the guest room of this mansion, that isnât too many, right?â
It doesnât matter if theyâre a lot because the patients gathered here are going to be everyoneâs practice subject after I teach them how to treat it.
âYes, no problem. By the way, I donât see them but the temple officials are here as well, right?â
âYes, theyâre waiting for us in the hall inside. There are seven people from the temple, including the Pope and the Saint. Iâve also brought three court physicians with me, can they join us?â
The court physicians? Itâs troublesome when aristocrats are involved, but considering the position of the king, itâs not good to âteach only temple officials.â
âYes, thatâs fine.â
When I entered the hall, the Pope came to greet me as the representative.
âGood morning, your Highness Luke. You discovered an effective treatment for labor cough and decided to teach it to us free of charge. I couldnât sleep last night, thinking, âIf itâs true that treatment is possible just how many lives will be savedâŠâ
âGood morning Pope. I hope my explanation is clear to everyoneââ
At first, I was thinking of wearing a mask to hide my identity, but Navi said, âhow could there be no one with appraisal magic at a gathering of high-level temple officials.â
I briefly introduced myself to everyone and asked them to take their seats in the dining room.
âWell, first of all, I will start with a lecture before the practical training. I worked hard last night to make a picture book that even a monkey can understand, so I will explain in detail how labor cough is transmitted.â
âDoes your Highness Luke think weâre on the same level as monkeys?!â
Who is thatâŠisnât he one of the court physicians that the King brought? As I recall, he was the one who was introduced as the youngest of them.
âItâs a figure of speechâŠ.even if you show it to a monkey, it wonât actually understand it.â
âWell, thatâs fineâŠI was wondering if you were making fun of us.â
ââȘ Heâs the type who makes a fool of himself. His tone is polite, but in his mind heâs looking down on master. ă
âIs that so? The King has brought a troublesome fellow.ă\
ââȘ Itâs true that heâs excellent. He seems to have liked Mifa, and he seems to have gotten irritated when he heard rumors that she had been engaged to Master, so letâs overlook it. ă\
âA court physicianâŠhas he ever seen Mifaâs breasts?â
ââȘ MasterâŠwhat are you saying nowâŠyou disappointing Princeâ*
âUghâŠbecauseâŠâ
ââȘ The examinations of the queens and princesses are done by the female physician. Sheâs also participating in the workshop this time. â
Is that so?
âLenglan! If you say anything else Iâll have you arrested! Engrave each of Lukeâs words into your head and learn firmly!â
Zeno-san is angry!
âMy King, Iâm sorry for the unnecessary remarks!â
ââȘ The court physicians were warned in advance that they should never make statements that would offend master.â
âWell, moving onâŠI will accept questions at the end, so please listen silently to my teaching until the end.â
I explained everything with the picture book I made last night. Everyone listened attentively to my explanation.
âDo you have any questions?â
The Saint raised her hand.
âYes, Holy Mother.â
âI canât believe that microorganisms do such invisible harm to the body. Iâve confirmed with my unique skill that His Highness Luke isnât lying, but I canât understand it. How did His Highness, Luke, know that something invisible existed and how did you confirm it?â
I was asked the same question by Iris yesterdayâŠafter all, âHow?â I guess thatâs where I get stuck when I think about it.
Next to the saint, the female court physician is holding her thumb and index finger in a circle and looks at her palm. What is that? The inside of the circle appears large as if she was looking through a scope.
ââȘ Itâs expansion magic. But that would only look as large as with a magnifying glass. â
When I saw the magic of the female court physician, an idea came to mind.
âThe answer to the saintâs question is the application of the magic that sensei is using right now. Have you ever wondered how the blue-black mold that grows on bread grows day by day?â
âThatâs the magic called [expansion]. Unfortunately, I canât use it. The phenomenon where blue-black mold increasesâŠ? I see. If you apply it to the explanation in the picture book, it means that parasites are growing on the bread and feeding on it.â
âThatâs right. Are there any knights with itchy feet?â
âLuke, do you mean athleteâs foot?â (Zeno)
âYes, thatâs rightâ
They donât even understand fungus, so how can they call it athletes foot?
ââȘ Even in Japan, the wordsâ athleteâs foot âandâ tamushi â {TN: google it if you want} were already used in the Edo period. It was also properly described in old literature. Since they didnât know the existence of the fungus, at that time they thought that insects in the water and insects in the rice fields sucked and itched like mosquito bites. Athleteâs foot = insects in water, Tamushi = insects in the rice fields are said to be the sources.â
âActually, itâs been bothering me for a long timeâŠ.can you do something about it?â
âThe nails arenât gone but itâs athleteâs foot.â
What? Itâs not showing with appraisal magic?
ââȘ The level of appraisal magic is too low. Athleteâs foot isnât a life-threatening illness, so at masterâs current skill level, it canât be seen by appraisal magic.â
âSince itâs not an illness, it canât be cured right?â (Zeno)
âDid the court physicians say that? No, itâs also a nasty illness that can be transmitted to others. The invisible microbes I just showed you are parasitizing between His Majestyâs toes. It can be cured as well. â
âReally!â
âBefore thatâŠI will collect a little of the skin that is the athleteâs foot.â
Letâs make a lens with water magic.
First, make pure water without any impurities and maintain the shape of the convex lens.
ââȘ Master, the idea isnât bad, but it isnât possible.ă\
âIf you stack several lenses, canât you magnify enough to see the athleteâs foot fungi?â ă\
ââȘ The lens used in a microscope is an objective lens. It has a complicated structure inside. Just collecting light like a convex lens does not provide enough precision to see bacteria. The image that Navi showed the other day is an electron microscope image. The principle is fundamentally different. â
âWell I thought it was too easyâŠâ
I have no intention of developing and providing an electron microscope.
ââȘ If itâs completely original, you can show everyone the athleteâs foot fungus right? Navi will assist you, so please create four lenses like before. â
This is what I did according to Naviâs instructions.
1. Suspend the skin collected from Zeno-san in the air with [Float]
2. Illuminate the skin from underneath with the magic [Light]
3. Add the magic of [enlargement] to the lens made by water magic.
4. Focus all four lenses created in step 3 on the skin
The fourth image was a super-enlarged piece of skin with threads that branched out like roots of a tree.
âOh, Iâve done it too!â
Looking towards the voice, the female court physician had completed my original magic, which Navi had predicted would be impossible to imitate, without her support.
âWell-done sensei! These thread-like things are the true nature of athleteâs foot. They penetrate into the skin, absorb nutrients from the skin then divide and multiply like slimes. Iris, as my first disciple, why donât you try it first? As I explained yesterday, use your magic with the image of removing this evil thing.â
Nominated among the brilliant members, Iris, nervously, treated King Zenoâs athleteâs foot.
I raise the level of appraisal magic to see if the treatment was successful.
âCongratulations Iris. The Kingâs athleteâs foot has been completely cured.â
âReally? Iâm so glad! Can labor cough be cured in the same way?â
âYou and I can only use intermediate magic, so we have to treat critically ill patients many times, but I think it will work.â
The King was happy that his athleteâs foot had been cured, but if he puts on those boots, it will come back again.
I told him that if he didnât clean everything he was using with [Clean], it would reoccur. Then, we went to the guest room where the patients were housed and started the treatment practice of the Pope and others.
âThe magic of the Pope and the Saint is amazingâŠIs that special-grade recovery magic?â
âYes, thatâs rightâŠI think His Highness Luke is more amazing. This treatment developed by His Highness is amazing. To be honest, Iâm surprised at how effective it is. How many precious lives have been lost so farâŠ?â (Pope)
âThis remedy also works for colds. This is probably the best way to cure other epidemics that can be transmitted to other people.â
âWhat! Itâs also effective against colds?â
âEach illness has a slightly different image. For example, if you have inflammation of the throat, your fever wonât go down unless you calm it down. Therefore, itâs necessary to have an image of suppressing inflammation. Although, it canât be said that the cause of the illness is completely cured. Iâm still in the process of research, so thereâre many things I still donât understand.â
When a high-ranking magician treats a patient with a severe case of labor cough using the method I taught, the patient can be completely cured with a single spell. As a teacher, I feel frustrated with this much difference in level.
âNavi, Iâm scared of the level difference âŠâ
ââȘ Thatâs right. Although the master has a higher understanding of the illness and better treatment efficiency, the results are dramatically different due to the difference between intermediate magic and special magic. The same can be said for attack magic, so level differences are scary. I want you to raise your level as soon as possible.â
On this day, 9 out of the 10 participants were able to learn this treatment. The sister who couldnât learn it was depressed, but I donât know if she didnât have enough imaging ability or she didnât understand it well enough. Well, Iâm sure sheâll be able to do it soon.
Iris, who was able to cure athleteâs foot, was also able to cure labor cough effortlessly. She showed me a very nice smile, I wonder if she was happy that she succeeded.
Oh yeah, the young court physician who was involved with me at first, is currently in a pitiful situation, surrounded by the guard knights and temple knights who had come as escorts.
Heâs surrounded by a lot of knights and is constantly treating athleteâs foot. In any case, the people gathered here today are all heavyweights in the country, so their positions and titles are all superior to the knights.
As expected, I canât casually ask the Pope or the Saint to treat athleteâs foot.
Thatâs why they flocked to the young man who had just become a court physician. My condolences.
âI have a lot of other projects I would like to research, so Iâll leave the rest to everyone here. Iâll give the picture book I made with Iris to the church, so please tell each temple branch about the cure.â
I threw the whole thing to the head of the temple before he could ask me to go to each branch and hold a seminar.
