Going out.
Downstairs.
Standing under the sun.
"Whew!"
The rolling heat waves hit her face, making it difficult to breathe in this hotness, but the temperature of the upper body seemed shielded, slightly cool, Ling Chan was amazed.
"It really is cool!"
Five minutes.
...
Ten minutes.
...
Half an hour.
...
"So effective." Ling Chan sighed, even after half an hour, it's still like this; it's really powerful. Moreover, Tang Qing mentioned that the duration is measured by days.
Twelve hours of extreme heat exposure.
Then.
The internal heat-absorbing material will reach a threshold.
At this point.
You'll need to cool it in a place below thirty degrees, but theoretically, there are few places nationwide where it's above thirty degrees all day.
Hence.
Normally, you can wear it for a long time.
And the cooling is automatic, very quick, at most half an hour to be reuseable for a day. Therefore, in most environments, there's no need for special cooling.
"Amazing!"
