Then he turned to Ruby and asked sternly, "Can you guarantee it? Guarantee that you won't harm any more innocent humans? Otherwise, I'd rather deal with you myself!"
Ruby seemed to have grasped a lifeline and hurriedly swore, "I guarantee it. I swear on the soul of this body!"
"Look, I didn't even kill this body." She anxiously rolled up her sleeve, revealing a deep, healed yet still gruesome slash across her wrist. "She came from the morgue. She ended her own life—I'm only borrowing it!"
Sam softened. He looked at Wu Heng, his voice pleading. "Lohr, let her go. She helped us. We can't repay kindness with hostility."
