Capítulo 600: Chapter 600 Qiao Yin's Test

Today was another day for Gu Guotai to receive treatment.

As always, the person accompanying him was his second son, Gu Chengsong.

This time, Qiao Yin actively struck up a conversation with Gu Guotai, occasionally bringing up her mother in the conversation intentionally.

Gu Guotai did not avoid any questions about her mother, and he even took the initiative to ask her, "Doctor Qiao, if it's not too much trouble, could you tell me how your mother passed away? I remember her being very healthy, and she was also a doctor, it couldn't have been due to illness, could it?"

Qiao Yin looked up at him, then glanced casually at Gu Chengsong without changing her expression, only to find that he was also waiting curiously for her answer. Apart from that, neither of them had any different expressions.

She answered in a low voice, "My mom was killed by a patient with a knife during treatment."

"What?!"

Gu Guotai was shocked, "Killed by a patient? Who? Why did he kill your mother?"
