Li Yu looked up at Zhou Jia and said, "Xiao Xi, did you check the victim's throat during the autopsy?"
"We didn't. Coroner Yang checked the victim's stomach and organs and said that he didn't find any signs of poisoning."
"Then go back and ask the coroner to check the victim's throat or the top of the skull for any red blood halo scars."
Zhou Jia asked in confusion, "Yu'er, are there any explanations for investigating these two places?"
"I heard from my master that someone harmed people like this." Li Yu had no choice but to mention her nonexistent master again. She told Zhou Jia about the few cases she had seen in her previous life. "Xiao Xi! I don't know if I can help you, but I can provide you with an idea."
