Xie Luan had heard about this matter from Gu Yan.
Although Gu Yan did not tell her the details of the incident, he was probably worried that she would overthink it or that Xie Luan would be afraid.
However, Xie Luan knew.
Gu Yan suspected that Bai Weiyang was the one who killed Zhang Lan and that she and Lu Ye had been searching for evidence.
Otherwise, Xie Luan would not have subconsciously taken a step back when she saw Bai Weiyang when she opened the door.
Murderers were terrifying, and they were even more terrifying when they killed their mothers!
Bai Mengchen’s hair stood on end when she heard Xie Luan’s words.
She had also suspected this before.
When Zhang Lan died, Bai Mengchen was in Bai Weiyang’s ward with that mysterious man.
As for Bai Weiyang, she wasn’t in the ward.
Where did Bai Weiyang, who was in poor health at that time, go?
