Lu Tingchen tousled Lu Liangwei's hair in an indulgent manner. Leaning close to her ear, he asked in a low voice, "Did you do something to her?"
Lu Yunshuang had always been a cautious person, so this incident of her tripping over a threshold seemed far too outlandish.
Previously, he would never have suspected Lu Liangwei. However, since coming back from death's door, not only had her character changed completely, but she was also displaying far more intelligence.
If she had done something to Lu Yunshuang, he would definitely believe it.
Lu Liangwei knew she could not hide what she had done from Lu Tingchen, but she had never intended to keep this a secret from him anyway.
She lifted a finger and waggled it in front of him, replying in an equally low voice, "I rubbed this silver needle with a medicinal substance that's instantly able to numb one's nerves."
