Half an hour later, the emergency room doors swung open, and a doctor emerged. Su Zhenggang and Leng Xuan quickly approached him.
"Dr. Chen, how is my sister?" Su Zhenggang asked anxiously, his face showing deep concern.
Dr. Chen removed his mask and gave a wry smile. "Captain Su, your sister's injuries aren't severe. She just lost too much blood. We've already transfused matching blood into her, so there's no longer any danger to her life."
Su Zhenggang breathed a sigh of relief and, trying to make light of the situation, joked with Leng Xuan, "I've always said my sister is a kindhearted person. Heaven wouldn't be that cruel, right? Haha!"
Leng Xuan also felt a weight lift from his heart and smiled faintly. However, his mind had already drifted to another matter. Who was behind this car accident? Could it be Cao Shaoyi again? If it really was him, Leng Xuan vowed not to let him live.
