"No, I can't undo it, but I can make it less painful when it flares up." She was just a witch doctor.
"However… I can help you plant a Gu bug in Lu Fenying."
"What do you mean?" Gu Bailu asked anxiously.
"If he uses the slave mark flute, the Gu will make him suffer a backlash. In other words, he'll feel as much pain as you do when he uses the slave mark flute." The witch doctor's empty eye sockets looked at Qian'er.
Qian'er shook her head. "I'm not scared of pain. I'm scared of being controlled."
That was the main reason why she wanted to leave. She would be able to endure the pain, but she would do something humiliating if her mind was controlled.
"The Backlash Gu is simple: You can do whatever he does to you." The witch doctor chuckled, which was an extremely scary sound.
Gu Bailu grabbed her hand in delight. "Really?"
That would be great!
