Yujing Summoning Institute, a place led by the Summoning Court of Wuji Continent specifically for summoners, where a Beast Language User can obtain certification as a summoner once they pass the Institute's assessment.
Feng Kuo promised Yun Sheng that he would not reveal her identity, so before Yun Sheng entered the Institute, he gave her a small gift, a trinket similar to an earring, which looked like a Demon Beast Soul Stone made into a piece of jewelry called the Illusion Power Earring, and it is also a special Magic Artifact.
About Magic Artifacts, Yun Sheng had encountered them once during a nearly fatal trap set by Ding Lei in Banana Leaf Village.
Simply put, Magic Artifacts are tools made by specialized Magic Craftsmen and imbued with special magic.
In this Illusion Power Earring, there is a permanent Fog Magic. When Yun Sheng wears the earring, even if she stands in front of another person, they cannot remember her face. They would only recall a mist shrouding her face.
