"What kind of joke is this? A cross-world summoning of a Pillar-level Demon's Projection? How could you possibly do something like that?!"
"It's already incredibly difficult to summon those Demons from the Abyss into Night Valley's human world. Now you've crossed the world barrier, and with only an array, you think you can summon Demons that have been eternally imprisoned in the Abyss?"
Potassium Chloride instinctively denied it.
A mocking laugh came from behind him in response.
"Heh... idiot. Of course one array alone isn't enough, but I also have a 'medium.'"
As soon as he finished speaking, Potassium Chloride... and even White Sand, who lacked the ability to sense magic, felt a chaotic, violent, and uncomfortable force surge forth.
"Crash!"
Black water gushed from the luggage rack in the passenger cabin, and Potassium Chloride's expression changed slightly.
"Abyssal Undercurrent!"
But... what appeared wasn't merely the Abyssal Undercurrent.
Within the water, Potassium Chloride saw a black, translucent crystal floating.
The aura surrounding it was ancient, powerful, and evil.
"Damn it... It's a Pillar-level Demon's [Root Demon Crystal]!"
At that moment, Potassium Chloride was already seventy to eighty percent convinced that the mastermind could summon a Pillar-level Demon across worlds.
After all, a Pillar-level Demon's [Root Demon Crystal] wasn't something just anyone could obtain!
The mastermind's voice rang out leisurely once again.
"What I prepared goes beyond this... Relying solely on my own power might not be enough, but... what if I add the [Professional Item] of someone with a 'Unique Profession'?"
As soon as he finished speaking, the two of them saw a figure sway to its feet inside the business-class cabin, seemingly sleepwalking.
The figure had originally been wrapped up tightly, but now it voluntarily removed its mask and face covering.
White Sand recognized the other party at once.
