The Vanishing Wand

Looking back, the request from the Luci Kingdom was pretty damn harsh.

I knew the request to investigate the bizarre artifact Quodenenets would be difficult.

But over the course of this journey, I gradually realized that it was not only difficult but also insanely dangerous.

The core of Quodenenets is a regular 24-cell, a four-dimensional geometric structure.

Four-dimensional geometry... Four-dimensional technology is dangerous.

Nearly twenty people died in the man-made accident in the Chengdu Concession, and Hiyori nearly died in the incident involving foresight.

There is technically a safety device for returning from four-dimensional exile to the third dimension, but its operating mechanism remains unclear. If we get something wrong, it wouldn't be surprising if an entire city disappeared.

In particular, if I carelessly tamper with Quodenenets' ultra-advanced four-dimensional mechanism—a supertechnology from a magical civilization, not some product of the elementary four-dimensional geometry Mr. Yamagami and I cobbled together from Mr. Hatobat's surviving materials—it might, at worst, wipe out the entire Earth.

It's fucking dangerous.

On one hand, I want to say, "Don't make me mess with something that dangerous," but I also understand that if anyone in the world could handle it, it would have to be the world's most dexterous AAA-rank human precision operator—Oori...
