Countless bubbles drifted up and down through the air.
At first glance, these bubbles looked like soap bubbles—thin and transparent—but they were far larger.
A single glance revealed at least tens of thousands... no, perhaps even hundreds of thousands of bubbles floating endlessly in midair.
Through their outer membranes, vague figures could be seen moving inside.

Combined with the bubbles' convex-lens properties, even though figures could be seen moving within, it was impossible to make out what they looked like or what exactly they were doing inside.
Looking at the seemingly endless bubbles overhead, a trace of hesitation flashed through Angel's eyes. "These bubbles..." They looked somewhat familiar.
Before Angel could voice the latter half of that thought, Napoli walked over to his side and introduced them with considerable pride. "Every bubble up there contains a production workshop."
Countless bubbles, countless interconnected production workshops—they formed the very core of the Artifact Embryo Factory: the production area.
"So the shifting figures in the bubbles... are actually craftsmen making artifact embryos?" Angel asked after hesitating for a long while.
Napoli nodded. "That's right. Is there a problem?"
Angel fell silent for a moment. Rather than answering Napoli at once, he changed the subject and asked another question. "These bubbles were provided by the Crystal-Eyed Race, weren't they?"

"If an accident causes an explosion while a craftsman is working inside, the bubble will also release special energy to suppress the force of the explosion."
"Not only that, Bubble Crystal Shells
