A voice echoes in the whole area, which is heard by everyone affected by the illusionary formation made by the Fae Race.
{Intruders! Prove that you are not our enemy but escaping this illusion you are in. If successful, you shall be welcomed as a guest. Once you fail, there will only be death waiting for you.}
The separated individuals had all heard this voice. After this voice had spoken, they were surrounded by a white fog that pulled them into some kind of illusion. This illusion is born from the hidden fear in their lives.
However, this kind of illusion is useless for some people. For example, people who don't have fear are simple, like Taiyang. People who experienced death like Tan Bingyu or Yue Xuexia are strong-willed and observant; distinguishing the truth from an illusion is normal for her.
