Previously, she had never used it, but now it could come in handy.
Jiang Xue extended her hand, flicked her finger, and a strand of Spiritual Energy instantly shot into Cheng Li's body. With the entry of this Spiritual Energy, Cheng Li was instantly paralyzed, unable to move.
After restraining Cheng Li, Jiang Xue quickly bypassed her and headed to her room. As her friend, Jiang Xue naturally knew where Cheng Li would hide things.
So, the moment she entered, she headed straight for the bed where Cheng Li slept. She knew that the more important something was to Cheng Li, the more she liked to keep it under her pillow.
As for Cheng Li, she wasn't controlled for long. She quickly regained her freedom; if it weren't for her personal experience, she would have thought that the paralysis just now was an illusion.
