"Hmm?"
In an instant, Lu Changsheng realized that there was an invisible barrier in Li Feiyu's mind, as if breaking through it would scatter his soul.
"This is... Spiritual Soul Prohibition!"
Lu Changsheng immediately knew what was happening.
This was a prohibition placed by Azure Phoenix Immortal on Li Feiyu's Sea of Consciousness, to prevent anyone from using soul searching techniques on him.
This technique was extremely exquisite and sophisticated.
Had it not been for Lu Changsheng awakening the Taichi Soul Body, his divine sense surpassing that of an ordinary Core Formation Peak, he wouldn't dare to act recklessly at this moment.
"I only need to modify some of his short-term memories recently, there shouldn't be any problems..."
Lu Changsheng's expression tensed as a golden figure emerged from his brow's Sea of Consciousness, sending out a beam of soul light that pierced directly into Li Feiyu's Sea of Consciousness.
