The Failed Swordsman Who Became the Strongest After Spamming the 100 Million Years Button

The doctor handed me a thick sheet of documents, filled with rows of sentences with medical terms that was too difficult for me to understand.

「Kukuku, what do you think? It’s amazing, right!?」

「S-Sorry, I’m not sure what’s so amazing about it…」

Unfortunately, I don’t have deep knowledge of medicine.

All I know is applying first aid for lacerations and puncture wounds which I learned during the lessons at Thousand Blade Academy. And the general knowledge for dealing with colds, headaches, and abdominal pain.

「Oops, sorry about that! Looks like I was a little too eager!」

Dr. Hap facepalmed himself, and approached closer to me.

「This chart pertains to the records of a “certain experiment” and its results!」

「A certain experiment?」

「Indeed so! Please don’t tell anyone else about this… Actually, I secretly cultivated Allen-kun’s cells behind the scenes, added various stimuli to them, and investigated their reaction!」

「I-I see…?」

Why were my cells secretly cultivated behind the scenes?

Why did he decide to add various stimuli to it?

That sounds like an ethical and legal problem to do such a thing without the person’s permission.

But I decided to listen to the continuation of the story for the time being.

「I confirmed something unbelievable through the experiment! Allen’s cells have an “abnormal adaptability” that a normal human being simply cannot acquire – a special power that can be called “acquisition of resistance”!」

「Acquisition of Resistance?」

As I tilted my head to those mysterious words, Dr. Hap powerfully nodded.

「If you drop the cells in poison, it will produce antibodies, if you burn it with high heat, it will gain heat resistance, and if you cut it into pieces, it will adhere to each other even stronger! To put it simply, the more damage you take, the stronger you become!」

Dr. Hap said something ridiculous.

「For example, have you ever had an experience where the second attack you received during a battle wasn’t as big as the first time.」

「…Ah, come to think of it…」

Ria’s flames, Claude-san’s bombing, and more recently, Von’s sand whale, and etc…

The pain was much more bearable the second time compared to the first attack.

Apparently, I wasn’t just imagining things. It seems that the damage was actually reduced.
