From Old Master Gong's words, it was not difficult to discern that he was hiding something. He just talked about how his son contracted the disease out of the blue, without any prior symptoms.
As for what his son did before he got sick and whom he had contact with, he all claimed ignorance and dismissed as unknown.
"All I know is just that," responded Old Master Gong.
"Oh, is it?"
Lin Caisang let out a cold laugh.
"Since Old Master Gong doesn't know, I presume there must be someone in the Gong Family who does? Constable Wei, would you kindly take some men to the Gong household and bring the young master's mother and her trusted family servants here. I would like to question them one by one."
"What?!"
At her words, Old Master Gong was startled. His face involuntarily turned pale.
"Miss Liu, don't you think you are crossing the line?"
"Old Master Gong, do you truly believe I am overstepping?" Lin Caisang intensified her tone, counter questioning him.
