The course continued, and Yukari learned a lot from instructor Kayama, who specializes in pathology. He promises to give Kina, who has become her friend, a copy of the "Teaching Book of Life Magic" written by Grim and Kalina.

　After the course, which was very fulfilling, Yukari returned to Shibushi City. When she went to the Adventurers' Guild for the first time in a while, she found that the topic of conversation was the defeat of the evil gods by the Grimms.

　Yukari spotted Maria at the reception desk and asked her about her story.

'Oh, you don't read the paper?'

I was too busy completing course assignments. I didn't have time to read the newspaper."

The evil god Chitkaa, who was sealed in the thirteenth layer of Narukami Dungeon, was defeated by Dr. Grimm, Arisa, and Chika-chan. They are getting great reviews."

What is an evil god?"

　Yukari tilts her head. Maria explained in detail from where she discovered the city of War Bear.

I'm like, "Wow, that's great. I'll have to hear from both of you."

　Yukari decided to contact not only Arisa and Chika but also Amane and Grim to meet. The place was Grim's mansion.

　　　◆◆◇◇◇◆◆◇◇◆◇◆◇◆◆◇◆◆◇◆◆

　It has been a while since Arisa and the other four gathered. Yukari looks at me.

Congratulations on defeating the "Evil God. It's getting great reviews. It was even in the newspaper."

　Yukari checked the newspaper at her parents' house and found an article about defeating the evil gods.

I should have gone with him.

　Amane says with regret. Yukari nods in agreement.

Yukari was in a medical mage course and Amane was working with professors on 'force brakes', right? It's not something that will affect your future."

　Alisa said pointedly, and they both agreed.

'Yes, but didn't they also raise the magic level?'

　Amane asked.

'Well, yeah. We've defeated the evil gods."

　Me, Arisa, and Chika told them the details of our defeat of the evil gods. Amane heard this and looked at Chika's tattoo.

The story has been stolen; if detected on Amazon, report the violation.

Chika and Arisa topped it off with a hover cannon. And Chika got the transfer gate key. ...... I knew I wanted to be there."

　Alisa and Chika looked at each other and laughed.

Amane and Yukari must have had their pick of the crop, too, right?"

　They nodded. It seems that Amane was able to register the magical technology that applied the "Forth Brake" as a magical patent with the Magic Office. That magical technology seems to have a wide range of applications when utilized as an emergency brake for vehicles.

　Yukari told me that with one more class, she would be able to become a certified medical mage. I was curious about the "body scan" that medical mages use for diagnosis.

Why are the results so different depending on who's using it?"

　I asked the question because I was concerned about the fact that some people are missing out on things.

That's because the BodyScan uses the user's knowledge to determine if they are sick."

　I see, if there is a lack of knowledge, the disease will not be determined to be a disease and will be overlooked. That would explain why medical mages need to have extensive knowledge of diseases.

That's a lot of work for a medical mage."

The government is thinking of increasing the number of medical mages and dividing them into specialties such as cardiovascular, gastrointestinal, and neurological."

　It would be less likely to be missed, but would require a very large number of medical mages.

And the medical mages have to give accurate information about the disease to the doctors, which is not easy.

　The medical mages seem to draw sketches to convey information, but they have a hard time drawing accurately.

You're either good at painting or you're not."

Dr. Grimm, can you do something about it?"

　According to Yukari, the information on the affected area obtained by the "body scan" will remain vividly in the memory for about five minutes due to magic. After five minutes, however, the information is erased from the memory.

　I felt uncomfortable when I heard that. Is magic erasing memories or something?　I wondered. Regardless of that question, Yukari's request was to contribute to medical care, so I decided to think about it.

By the way, I need a favor, too.

　When I remembered that I might need the magic of "Detox," I asked Yukari to store the "Detox" in a magic absorption alloy and asked Arisa to analyze it.

　Alisa turns to me and asks.

Are we going into a dungeon with poisonous demons?"

I have something I want, and I'm thinking of going on an expedition."

'Expedition. ...... I'd love to go with you, but I can't take time off from my college classes.'

　Alisa said ruefully. Even if I could take a day off from college, I would not be able to take Alisa to the blockade dungeon. Just as well, I thought, and asked about Chika and Alisa's college life.

　The next morning, after breakfast, I went to the workroom. He decided to consult with Metis and plan countermeasures for the tree dungeon.

Metis, do you have any information on tree dragons?"

Unfortunately, we have no information. But there are two possible ways to defeat them.

What is the method?

One is a long-range attack using hover cannons."

　The tree dragon's tendrils are about 70 meters long, he said. If you attack it with a hover cannon from a distance longer than that, Metis said, you might be able to take it down. He said it is not a sure thing.

What's the other way?"

'It's a fire attack. Plant-based demons tend to be weak against fire."

Come to think of it, there wasn't any life magic that could set them ablaze with flamboyance."

　There is such magic as "Heat Arrow," which heats up the body, but it does not produce flames. There are offensive magic spells such as "Prominence Nova" and "Super Nova," and Metis is referring to such magic.

Is the D-particle flammable?"

　I tilted my head. Burning is a chemical reaction, a combination of oxygen and matter; I don't think D-particles combine with oxygen, so the magic would be to envelop the object in a kind of high-temperature flame.

'So would that be the magic of wrapping them in super-heated D-particles?'

I don't think we need to be concerned about D-particles. You can collect elements in the air, heat them and turn them into plasma.

　I understand what you said, and I agree. If that is the case, a form like a jet engine might be a good choice. In this era, advanced jet engines could not be built because of the lack of electronic control, but primitive jet engines existed, and so did jet airplanes.

　Jet aircraft were developed around the time of World War II, so they use a sophisticated form of jet engines from that time.

　When I was thinking about new magic, I wondered if it was necessary.

I'm starting to think that instead of developing such magic, it would be better to use 'flash moves' to get close to them, spray oil on them, and light them on fire."

'Oil-burning temperatures may not be enough to damage the tree dragon.'

　It seems that temperature is important for damage.
