The Cause

"Go!" I told Bob.

We started walking slowly, me in one direction, Bob in the other.

Evelyn and the others looked at us strangely. Even the bisons in the distance stopped grazing and turned to stare.

After about twenty meters, I shouted, "Stop, Bob!"

I summoned my gunblade.

"Indra!"

It appeared in my right hand, majestic as always.

Then I released it, making it vanish into thin air.

"Okay, Bob. Walk again!" I called out.

We continued. At around forty meters, I repeated the process. I was still able to summon Indra without issue.

Then we reset and did it again. Sixty meters. Eighty meters. Each time, I tested the summon.

"How far do you want us to keep walking, Alan?!" Bob shouted. His voice was faint at this distance.

"Just keep going!" I yelled back.

We reached around a hundred meters.

"Okay, stop!" I shouted again.

Bob halted.
