The prototype of the Geometric Lock was a three-dimensional geometric Rubik's Cube lock. It could grow large or small—when enlarged, it resembled a cramped meditation chamber; when shrunk, it was like a Rubik's Cube in one's palm.
After Angel integrated the "Spatial Embryo" into the Geometric Lock, its overall appearance did not change noticeably. However, the black-and-white squares on the cube became deeper and more remote.
The black was like the curtain of the void, flickering now and then, like starlight spilling down at a glance. The white was like hazy luminous mist, its edges bright and radiant, as though gilded by sunlight.
Aside from the deeper colors, Angel could sense that the internal space of the Geometric Lock had clearly expanded.
Previously, it could perhaps only expand to the size of a single-person meditation chamber, cramped even for someone sitting inside.
But now, it could directly expand to five or six times its original size—roughly the size of two classrooms.
However, the size of the internal space did not mean much to the Geometric Lock. It was not meant for storage; once the Geometric Lock shrank, the space inside shrank along with it.
The main use of the enlarged Geometric Space was to isolate the aura of large objects.
However, that use was not particularly important for the moment.
What Angel cared about most was still the Geometric Lock's efficiency in isolating energy auras—and whether it could isolate mysterious auras as well.
With that question in mind, Angel took out the Dream Conch.
He did not activate the Dream Conch. Instead, he used only the mysterious aura it naturally emitted to test the Geometric Lock's aura-isolation effect.
A moment later, Angel had a rough result.
The Geometric Lock's suppression and isolation capabilities had improved by roughly two to three
