As the hands of the mechanical watch turned, a circular area in the middle of the workbench gradually rose, quickly ascending into a cylinder one meter tall.
Fixed in the middle of the cylinder was a syringe, and through the transparent part of the syringe, one could see it was filled with a blue liquid.
Lin Shen originally thought it was a smart brain device or, at the very least, a projector of some sort that could provide some information. He didn't expect it to be just a hidden space containing a syringe.
Lin Shen reached out and took the syringe, the space within the cylinder was designed to store this syringe specifically, its shape perfectly fitting just that one syringe, nothing else, not even an instruction manual.
Examining the syringe in his hand, he found a steel stamp on the metal casing, with a few words engraved on it.
