"Hiss hiss, it feels suddenly much colder." Tangmo snuggled up next to Luo'er and shivered slightly before speaking.
"Maybe it's because the space got bigger, so it's no longer as temperature controlled as before." Luo'er looked around; all he could see was darkness, their Magic Crystal flashlights illuminating nothing.
In fact, it was mainly because their equipment was not good. The principle of the Magic Crystal flashlight's illumination has been mentioned before: it uses the cold light produced by activated Runes for lighting. This technology is almost identical to electronic lighting technology on Earth, the only difference being that one relies on magic power and the other on electricity.
