Jin was no doctor, so he had nothing to contribute by staying in the surgical theatre of the recovery instance when the Panda Nurses pushed Yuan Ba into the room. It was also the first time Milk and the Panda Nurses were using it. This was because previously there was no situation that required the surgical theatre. Most injuries' recovery was aided by the System and the Panda Nurses. Milk was just hanging around to accelerate the recovery process every now and then. Though, just as Yun before her, she primarily acted as a mediator or counsellor..
However, this time was different. She would be utilizing her surgical skills which she had not been using for years, if not decades ever since she was accepted by the System. "So Milk was a doctor before? I thought she was a Priest Class with a Monk subclass? I am confused." Jin asked the System in his head to clarify as he and Yang Ling entered the upper floors of the surgical theatre to witness the surgery without becoming a hindrance.
