In the evening, Old Yang and I sat in the hospital room accompanying our son.

I spoke about the discovery I made during the day: "The person who entered our apartment is the stepson from the marriage six years ago between Lu Jiajia and Su Fugui, who served more than five years in prison. The person following you is named Lu Jiajia, supposedly Zhang Fengxia's 'cousin,' but their household registrations are poles apart."

The young girl we encountered at the coffee room door, who glared at me angrily, should also be part of their group.

Old Yang rubbed his chin and analyzed in detail:

"These cases are typical examples of controlling victims mentally to commit crimes."

"The manipulators don't commit the crimes themselves. They use methods such as restricting personal freedom, abusing, inciting, and causing victims to harm each other, leading them into a state of learned helplessness and despair."

"By that time, humanity, bottom line, morals, and the law would no longer matter."

"Summer Assad's ex-wife must have been like this; she was certainly brutally trained before killing the first person."

"Unfortunately, she refused to say anything for the sake of her daughter."

We were whispering while our son listened from the back. Suddenly, he shouted, "The girl who pushed me down the stairs is one of them!"

"How do you know?" Old Yang frowned and asked.

We have a mutual understanding not to reveal details of unresolved cases to others.

Now that he can deduce it, there must be other clues.

Son: "She wasn't that strong; I normally wouldn't have fallen that hard. I was just too surprised at the time to grab the handrail in time."

Me: "What did she say?"

Son: "She said you would get her mother killed, and that all those who died were guilty of huge and unforgivable crimes."

Old Yang: "For the child to say that, it shows they aren’t randomly targeting wealthy bosses; it's more like revenge."

Me: "Feng Qihang previously refused to call the police, saying he did something wrong, together with other workers, taking his brother's compensation money. Could Summer Assad be one of those workers?"

Old Yang: "And there's also Lu Jiajia and Su Fugui."

I nodded and looked at my son.

Only when we confirm this group's crimes will I be relieved.

I'm just afraid that the closer we get to the truth, the more desperate they will become.
