Not mentioning how the police conducted their investigation, Chen Yu had already begun treating the patient.
No matter who the person arriving was, or what he had done, once he entered the hospital and truly needed treatment, then he was a patient, and the doctor would do his utmost to treat him.
The patient in front of Chen Yu was no different; he might have been related to the two previous homicide cases, or perhaps he was the murderer in those cases, but Chen Yu didn't care about that. For him, he just needed to consider how to cure him.
The cancer cells had spread throughout the body, which normally meant there was no need for treatment anymore, just like Chen Yu had told the two policemen, under such circumstances, doctors no longer considered treatment, but rather how to extend the patient's survival time and improve their quality of life in the last stage of life.
But for Chen Yu, he was somewhat keen to challenge the impossible.
