I'd like you to take a look at this medical record right away!

　The thick document he handed me was lined with difficult letters that looked like medical terms, and just looking at it made my eyes sting.

I'm not sure how I feel about that.　Isn't that great?

"I'm sorry. I'm sorry, I don't know what's so great about it. ......

　Unfortunately, I don't have a deep knowledge of medicine.
　The only things I know are the first aid for lacerations and stab wounds that I learned in my classes at the Thousand Blade Academy, and the most common ways to deal with colds, headaches and stomachaches.

Oops, that was rude!　That was a bit brash!

　Dr. Hapu tapped the top of his own head, then nudged his face toward me.

This chart contains the records and results of a certain experiment!

"An experiment?

"Yes, yes!　From here on out, I'd like you to keep this to yourself. ...... In fact, I've been secretly cultivating Allen's cells, applying various stimuli to them, and studying their reactions!

"Oh, I see. ......?

　Why were they secretly culturing my cells in the background?
　Why did you want to add various stimuli to them?
　Isn't it an ethical and legal problem to do such a thing without your permission?

　To be honest, there were many things that bothered me, but I decided to listen to the rest of the story.

The results of the experiment revealed something outrageous!　Allen's cells had an unusual adaptive ability that no normal human being could have - a special power that could be called 'acquired tolerance'!

"What, acquired tolerance ......?

　When I tilted my head at the completely unfamiliar term, Dr. Hap nodded vigorously, "Mm! Dr. Hap nodded vigorously.

If you're not sure what you're looking for, you can always ask your doctor.　Well, to put it simply, the more wounds Allen-kun gets, the infinitely stronger he becomes!

　Dr. Hapu snorted and said something outrageous.

"For example, have you ever experienced something like this before?　For example, have you ever been in a battle where the first time you were attacked, the second time was somehow not so bad?

I'm sure you'll be happy to hear that. ......

　You'll be able to get a lot more than the first time you're attacked.
　The second attack was far less painful than the first.

　Apparently, it was not just a misunderstanding, but the damage was actually reduced.
