Leon Greyrat: The Second Son - Mushoku Tensei OC

Chapter 77 - Failed Experiment

— Leon Greyrat —

While I had intended to leave for the Sword Sanctum by today, I remembered that Rudy's fifteenth birthday would be in a week, so I decided to put my departure off until then.

I would definitely be cutting it close, as the trek to the Sword Sanctum from Sharia was around a month and a half, but if I used the trick I used back when I used to travel between Roa and Buena Village in constantly healing my horse, I should be back in time to see the birth of my child.

Usually, I would either be training in my backyard, spending time with my parents, or sitting around with Roxy, but for now, I was asked to come along with Rudy to help Nanahoshi with her experiments.

I knew that this was a long process with the final goal to return Nanahoshi to her homeland, but when I asked where exactly that was...

"Ah... I'm... from another world," she said evenly.

"Oh... I see," I said, nodding.

I certainly should have been more surprised, but for some reason... hearing that didn't shock me in the slightest.

In fact, it only seemed natural to me.

I wonder why that was...

"So, what are you trying to do today?" I asked. "More specifically... why does it concern me?"

I knew nothing about summoning magic nor magic circles, and while I had mana unlike Nanahoshi, I would be out after a few circles, while Rudy had enough to do this like it was nothing.

"We're summoning an object from my world," she explained as she laid out the large magic circle. "And as for why we need you, Rudeus mentioned that you had a Demon eye that allows you to see magic. I want you to watch the experiment and see if you can tell what is happening."

"I understand. And I'm guessing that I'll also be telling you if something goes wrong?" I asked.

"That... won't happen," she said, clenching her fist. "This formula is the pinnacle of summoning magic. Everything is as perfect as possible, so... it won't happen."

"Including another teleportation disaster, right?" Rudy asked.

Uhh... what?

"I am sure," she replied. "The conservation of energy applies, so the mana will be used up in the teleportation. The only reason that happened before was due to having no way to control the extra mana, hence the magic circle and your controlled mana input."

I already knew that Nanahoshi appearing in this world was the cause of the Displacement Incident, or at least an after-affect of it, but it was nice to know that it wouldn't happen again.

"...Alright then," I nodded.

And with that, the experiment started, with Rudy crouching down to feed his insane amount of mana into the formula.

It was so damn bright... but with how much I've been using my Demon eye, I've been able to block out certain sources if I really focused.

After all, without being able to do so, I would be blinded by the latent mana in the air whenever I tried to use it.

So, I saw it.

I saw the mana flow and churn through the magic circle, speeding up in some places, jittering in another, and as it crossed a certain line of ink... it escaped.

Boom!

A small explosion erupted on the magic circle, leaving a large gash of singed paper, the smoke rising in a disappointing black plume.
