章節 60: 57 Doomsday Girls Disappearance 2

GPS stands for "Global Positioning System" in English, which theoretically can cover most of the Earth's surface and near-Earth space, or at least that's what my online research suggested.

However, now I couldn't receive the GPS signal from Mazao's device.

How should I interpret this situation? Had Mazao gone to an area with poor signal, or was there a problem with the device?

I should first rule out the battery life of the bracelet. The red GPS bracelet on Mazao's left wrist had a standby time of three months, and it was fully charged when I put it on her; secondly, it shouldn't be water damage from her bathing, as I had specifically confirmed that the bracelet was highly water-resistant.

Maybe she had realized there was a problem with the bracelet and immediately destroyed it… Was that really the case? Given the gentle way she spoke to me when we parted, it was hard to imagine she realized my true intentions towards her.
