Seven-colored illusion god miasma was no ordinary miasma.
This miasma could erode magical power and the divine soul, making it impossible to use the Divine Soul Detection Art within it.
Even defensive barriers formed from magical power would be corroded and breached.
Once the seven-colored illusion god miasma entered the body and came into contact with the Primordial Spirit Avatar, anyone lacking a firm will would immediately sink into an illusion.
This was merely Misty Underworld Star's first defensive barrier.
It was said to have other defensive measures as well. For outside cultivators, slipping inside unnoticed was almost impossible.
"There are rumors that even an Eternal Giant in the human immortal realm would struggle to control themselves if the seven-colored illusion god miasma eroded their primordial spirit. I wonder if that's just boasting?"
Lin Fei's spirit body felt an eager urge to try it.
He wanted to see whether the seven-colored illusion god miasma could affect him despite the strength of his will.
A puzzled look appeared on Xiao Yifei's pretty face.
"If the seven-colored illusion god miasma is so powerful, how do the Nalan Family's cultivators get in and out? They must have some protective magical treasure, right?"
Lin Fei shook his head.
The hidden clan cultivators whose souls he had searched had all possessed relatively low cultivation, and they knew little of the Nalan Family's secrets.
"I don't know either."
"We'll wait out here. If we spot a Nalan Family cultivator flying out or trying to enter, we'll seize the chance to capture one. A soul search will tell us everything."
Lin Fei and Xiao Yifei hid in the starry void and waited quietly.
Although golden core realm cultivators could fly through the starry void, their magical power was limited, and so was the distance they could travel.
