The dark light that Jiang Li struck out entered the outer sect disciple's head. A thin, pale green, and translucent line floated in the air and connected Jiang Li's finger to the disciple's head.
After waiting silently for a few minutes, Jiang Li hooked his finger, and the green threads pulled out the black light that had entered the other party's head.
This black light was none other than the ghost that Jiang Li had captured.
At the late-stage Qi Refinement realm, Jiang Li could already use the Ghost Wood Art to summon a few ghosts to serve him.
The green line was the Ghost Wood Art's binding on the ghost, preventing it from escaping even if it left Jiang Li's consciousness. It could only obediently work for him.
This ghost had a certain ability to read minds. Although it was not strong, it could still be used.
Jiang Li sent it into the brain of the disciple in front of him to see if he could read any useful memories.
