Lin Yun watched helplessly as the man who looked just like him undressed and helped him into his clothes. Then he took a transparent object off his index finger and stuck it on his hand—this was the Mutual Awareness.
While showing these actions, the voice-over was also explaining the original Lin Yun's plan.
"This body is a gift from heaven, with an empty Qi Sea, devoid of cultivation level, perfect to use the Soul Imprint Spell on him."
The Soul Imprint Spell is something that can only be used by those of a higher realm on those of a lower realm, forcefully infusing one's own intentions into another person.
This is a method used by people of the Demon Sect to enslave others, and the original Lin Yun learned it by leveraging his good looks and learning from the maidservant who took care of him.
It wasn't a particularly sophisticated method, nor had it drawn attention from others.
