Xiao Lijin wasn't angry, she was a doctor and a woman, so having such thoughts was quite normal.
However...
"Qingzhu, if I didn't kill them, you saw it too, to protect the secret, they would have killed themselves," he said calmly.
"That's their business, not ours; I don't want to see you killing people next time."
"Okay, I promise you."
Xiao Lijin truly meant his promise to her, after all, if she didn't like him doing something, he wouldn't do it.
Bai Qingzhu also felt a bit embarrassed, she had indeed been too impulsive just now.
"Does... does it hurt here?"
He took the initiative to embrace her, "It doesn't hurt, Qingzhu, I can feel that you are concerned about me, you don't want me to kill them, actually you're afraid that many people will seek revenge on me. You're right, before I had no one to think about, Grandma and my parents had their protectors, but now I have you and Miaomiao, I can't act without considering you both. I realize my mistake."
