The main function of Mirror Replay was much the same as that of a recording stone: it could record scenes that had happened before and reflect them anew through a mirror.
However, while their main functions were similar, Mirror Replay contained a tiny bit—by which one meant an astronomical amount—more detail than a recording stone.
Through the mirror's ability to perfectly reflect, Mirror Replay could record every last detail of the magical fluctuations, pheromones, and even the energy feedback woven between the atmosphere of the environment and the subject at that time.
In terms of viewing experience alone, Mirror Replay was naturally far superior to a recording stone.
However, though Mirror Replay contained many details, that did not mean they were all advantages. Some details were drawbacks. For instance, it had a recording decay mechanism. The longer the interval, the more incomplete the replayed content became.
The decay period generally began half a month after the recording was made and continued for around a year. After a year, Mirror Replay completely forgot everything it had originally recorded, whereas as long as a recording stone was not destroyed, the images within it would endure forever.
This recording decay was actually a form of self-protection mechanism for living beings. After all, Mirror Replay contained far too many details. Preserving them indefinitely would only make future Mirror Replays more difficult; cumbersome and useless information filling one's thoughts would only become a burden.
