This Heart-protecting Mirror was obtained by Yan Mei from the Nuor Small World back in the day.
The Nuor World is a small world with no signs of life, here there are no humans, no demon beasts, no plants. The whole world except for the twin suns in the sky has nothing but an expanse of construction covering the entire continent.
This Nuor World, according to Lu Lin's conjecture, should be a world created by some advanced civilization, but for some reason, the whole world shows no signs of life.
The Nuor World is still quite famous among the Nine Sacred Lands of Longyuan. When it was first discovered, nearly all members of the Nine Major Sects went there to explore, but after thousands of years of exploration, there was not a hint of discovery.
In the Nuor World, there are only houses, buildings, and some things that will not be eroded by time, mountains, valleys, nothing else at all.
