After hearing Chen Yenan’s account, some of Zhao Tiezhu’s questions had been answered, but new ones emerged. He asked casually, "Since you didn't find anything and the matter is long past, why did you have to kill Zhao Kexin and his wife?"
He didn't believe for a second that this was some act of aggression by Lu Qianjin.
Chen Yenan thought for a moment before replying slowly, "No one found the Longevity Flower, and the bosses weren't willing to let it go. They spent two years investigating in secret, and they came to suspect that Zhao Kexin might be in possession of those two things. After looking into the areas Qin Xiaohan had frequented, they realized Zhao Kexin’s house was the only place they hadn't searched. When they secretly tore the place apart and still found nothing, they simply killed them to cover their tracks—to ensure no one else would ever know."
