Eden, the dormancy area.
Countless mechanical humans are neatly queued outside, entering the factory in batches, proceeding to their respective dormancy pods to undergo the vaccine recovery process.
Compared to living creatures, these mechanical humans are much more obedient. They don't resist; they even walk to their corresponding dormancy pods, lie down, and cover themselves up before beginning their 'dormancy'. The vaccines will be extracted after the disassembly of their bodies, while the disassembled parts of the mechanical humans are sent to the mechanical processing plant for reconstruction.
The energy modules of the newly manufactured mechanical humans have also been switched to the standard power supply mode of the Star Spirit World, powered by Demon Crystals.
The entire process is automated, requiring no supervision from living creatures. Vaccines are being produced one bottle after another.
