By the time Captain Wu received the call, Ling LAN had already been sedated by the medical staff and had fallen asleep on the hospital bed.
His colleagues who had stayed behind at the hospital told him that Ling LAN had woken up in the middle of the night after the surgery. When she first woke up, she was still fine. She wasn't noisy, just staring at the ceiling in a daze. It was late at night, so they didn't take any notes. They thought that they would wait for the team leader to come tomorrow morning and ask him in detail, but they still called the nurse on duty to check and confirm that there were no problems.
