Under the soft, dim yellow light of the lantern, Lin Yu saw a palm-sized portable device with a white metal casing and a row of black plastic knobs along its side.
Although he had no idea where Mans had gotten it, Lin Yu could understand its purpose just by looking at it...
This thing was indeed related to "Mental Power."
After all, it was clearly a typical Mist Island-style creation, carrying the simple yet practical technological feel of the Previous Civilization of Mist Island.
Lin Yu focused his Mental Power perception on the item. Before Mans could even introduce it, he had already figured out its use and general operating principle.
Although the technology used to manufacture this thing might have been profound, its working principle was quite straightforward.
"This thing isn't used to store Mental Power. It records the frequency bands of 'Mental Power fluctuations,' then repeatedly releases identical Mental Power fluctuations, like a 'Mental Power recorder,'" Lin Yu said. "Using it to record the 'healing' technique I perform on you so that you can continue enjoying the sensation after I leave is certainly a perfect match for the job."
The little white box stored a large amount of pure, tranquil "Mental Power."
As long as he fed his own Mental Power fluctuations into it, the box could copy, store, and release Mental Power with the same fluctuations.
The kind of soul massage he performed on Mans consumed very little energy to begin with, so the storage in this little box could be used over a thousand times.
Moreover, before it ran out, if Mans could find another identical device, he could use the new device to record and store the Mental Power fluctuations released by this one, achieving "transcription" and "refills."
If Mans also had a way to
