If they had known that Gu Ning's medicine could cure serious diseases too, they would have been shocked.
Jiang Zezheng wasn't seriously injured, and the injuries healed a lot under the effect of Gu Ning's medicine, so the others were about to leave.
Jiang Zezheng planned to call his family so that his family could come and take care of him, but Gu Ning said, "You can leave the hospital tomorrow, and your family will be worried if they know that you're injured. Why don't you make an excuse to stay here for a night and then go back home tomorrow?"
Gu Ning wasn't creating a chance for Zhu Yuanzhen and Jiang Zezheng to share some private time; she really believed that it wasn't a big deal. It was still up to Jiang Zezheng whether he would do it or not.
"Well, we're all busy today. Who should stay here to take care of Zezheng for a night?" Gao Chengyun said. He misunderstood Gu Ning, and became a wingman without delay. They were all actually free tonight.
