"Is it really that bright? How does it compare to the sun?" Xu Ying pointed upwards.
"I'd rather look directly at the sun than stare at that crystal," the monster concluded.
It's actually more dazzling than the sun?
"It sounds a bit scary... Does it have a high temperature?" Xu Ying asked.
"No, just brightness, it doesn't affect the surrounding temperature," the monster said.
Oh...
This is quite different from crystals on Earth.
The light emitted from the crystal, including the treehouse core, carries a certain amount of heat. During the previous winter, as long as the treehouse core was brought out, the surrounding temperature would rise.
"If you can't look directly at it, it would be difficult to extract the Source of Life you need from the crystal," Xu Ying said.
"Not that big of a problem," Xu Xin looked out the window.
Although it was daylight in the World Tree, the sun was not visible.
"If we want to look at the sun, we just need to wear sunglasses," said Xu Xin.
