Limitations
'Oh? Does that mean it can affect the time?' Lothur asked the system with a surprised expression on his face.
[Correct.]
'Could I use it to go back in time?' Lothur asked, imagining that he could manipulate a region of space that would take him back to when the Diamond-grade Soul Bone was destroyed right before his eyes.
[No. That would be impossible. The most the Space Watch can do is to speed up or slow down the passage of time within the region of space it created. While inside it, one would have the experience of living for years, while outside it, days or weeks would have passed.
The opposite could also happen, slowing down the passage of time within such a spatial area. In a sense, this could take the person inside that region into the future.
Time travel to the future is possible. But, to the past, it's impossible. Only the Time Crystal can do that.]
