After Returning Home
“Taking care of the slimes, checking the research plan, dinner with the Goblins, bath... I’ve done everything I needed to, so now...”
As night fell, I decided to spend the free time before bed thinking about magic with the slimes.
Then, on a whim, I called over a mud slime that was idly lingering by the waterside in the corner of my room, which I had prepared for just such occasions, and tried “shared sensations.”
“Hmm...”
This sensation sharing is one of the beast taming magic techniques, mainly used for gathering information.
Usually, it’s used to share vision, but hearing, touch, and taste can also be shared.
However, since slimes lack sensory organs, it’s said that sensation sharing has no effect on them.
That’s what Mr. Reinhardt and others told me when I was taught sensation sharing.
In practice, vision, hearing, smell, touch, taste—the five senses generally known—do not come through from the mud slime.
But the real experiment was next.
This time, I shared “mana sensing,” meaning the ability to sense mana itself.
This is a necessary step both to learn magic and to use it.
Mages, depending on the individual, can sense mana.
So this is undeniably a real “sense,” not just a feeling.
You might even call it a “sixth sense” after the five traditional senses.
From my experience researching slimes, through hypotheses and testing, my personal impression is that mana is often involved in many aspects.
For those reasons, when I tried sharing the mana sensing ability, right after feeling a slight resistance...
“! Ugh... ah!!”
What I felt was a shock—an overwhelming flood of “information.”
I couldn’t understand each piece; I could only try to withstand the torrent of data flowing in.
My body quickly grew hot; dizziness, nausea, and headaches began to arise.
It was a fatigue that reminded me of overwork in my past life.
Back then, even when feeling ill, I had to keep working.
But now is not the time to push myself, and no one will blame me for stopping.
I immediately cut the connection of the sensation sharing, blocking any further influx of information.
That gave me a moment to breathe, though I still found it difficult to stay awake for a while.
“This... needs caution and investigation of the cause...”

By the next morning, I had recovered.
I had work and study scheduled at the hospital that day, so I used spatial magic to travel to the city and then the hospital.
After changing into a white coat prepared just for me in the dressing room, I reported to the medical office’s waiting room.
Doctor Mafral, leading the group, and five other doctors from the Duke’s household had already gathered.
“Good morning!”
“Good morning. Thank you for your continued cooperation today.”
We began the morning meeting, confirming the day’s tasks.
As we reported communications about individual duties and research, there was some spare time.
So I asked a bit about last night’s symptoms, since this is an important period and I wanted to be cautious.
Even though the symptoms were temporary, I wondered if anyone knew of similar cases or causes.
The conclusion was:
“At present, there seems to be no physical problem. The cause is likely ‘mental stress’ and ‘fatigue.’ It seems you strained your mind rather than your body.”
Mental stress meaning psychological burden, and brain fatigue, probably?
“Yes. No special treatment is necessary. If anything, ‘rest’ is advised, but if you feel fine, you can continue as usual.
However, the process leading up to the symptoms is intriguing. You shared sensations with a slime, and a flood of information entered your mind... I’ve heard that inexperienced spellcasters sometimes mix the sensations from magical beasts with their own, causing nausea.”
What Doctor Mafral was referring to is similar to feeling sick from shaky camera footage.
That did happen when I first started practicing sensation sharing.
However,
“The feeling was different from what you described. It was like being forced to rapidly read through a huge stack of documents...”
