There are two exams at the Earthria Magic Academy, a written test and a practical test.

　Assuming 100 points on one side is the highest score, the full score is calculated to be 200.

　Crunchy.
　Crunchy. Crunchy.

　There was a creepy sound of a pen being run in the quiet examination room.
　The written exam consisted of three subjects: 'General Education', 'Magical Language' and 'Magical Engineering'.

　First, general education.
　It was so easy that it is strange not to be able to solve it.

　As for the contents, there were many questions about simple mathematics using figures and reading comprehension.
　
　However, this kind of test was sometimes required even two hundred years ago.
　It's just a "general education" test, and the content hasn't changed that much compared to 200 years ago.

　In other words, it's an exam that I can't make a mistake on.

　Next is the magic language.
　The next is the magic language.　It was at the level of "I'm not sure if this is the right level for me.

　It was a low level of witchcraft in this era, and it was further lowered for students, so for me, it was a problem that was lacking.

　Of course, there was no way I could get anything but a perfect score, and if anything, I found four mistakes by the examiners.

　And the last exam was magical engineering.

　This one was a little more difficult than the first two.

　It seemed to show the mean character of the examiners.

　However, even though the hurdle has been raised a bit, of course it's still easier for me than twisting a baby's hand.

　Oh dear.
　If I keep this up, I'm going to pass the exam with perfect scores in all subjects.

　Apparently, the next one is the last question.

　Question 12 From the Last Theorem of Depolnix. Prove below that the human soul cannot be created by magic.

Hmmm?
　At the end of the day, you're popping up with a different set of questions than you've ever had before.

　The level of difficulty of the questions has also increased to a level that is unparalleled in the past.

　Perhaps this question was set up with the purpose of preventing the students from getting a perfect score.

　I can't help but feel my cheeks loosen up a bit.



　Because it was me, of all people, who created this problem in the first place.

　It was 200 years ago, when I was a child of less than 10 years old.

　Back then, the world was in the height of the Human Body Refinement Boom, and all sorts of sorcerers were searching for ways to create a human soul.

　Some of them were discovered to have been taking away the lives of numerous human beings, calling it 'experimentation' by famous magicians, and it had become a social problem.

　It's really ridiculous.
　Even though it is impossible to create a living soul through magic.

　That's why I decided to put an end to this pointless boom by publishing "The Last Theorem of Depornicus" anonymously.

　Well, it wasn't a meaningless thing for me to do, since I was able to complete the 《Transformation Magic》 as an extension of my research results at the time.

　A quiet moment.

　Even though the difficulty level had increased compared to the past, this was just a 'service problem' for me.
　After all, the first time I solved this problem was when I was a child of less than 10 years old.

　I was the only one who knew that the name "Depornix" came from the name of a dog owned by an elderly couple who lived in the neighborhood.

　So there you go.

　In hindsight, the "Last Theorem of Depornicus" that I published at the time was somehow useless and incomplete.

　Good grief.
　Even though this was in my childhood, I was ashamed of myself in the past for publishing such an incomplete work.

　I would end the written test by describing an answer that made up for the shortcomings of the existing Depornix.
