"That's what I've been investigating." Eventually, Mu Lin didn't inform Tang Qishan about the Sky Network Organization, or Mi Zheng's identity.
The reason she told him some of the truth was that she needed his help; however, Tang Qishan was not satisfied with the answer she presented, "Did you find anything?" He wanted to know.
Mu Lin nodded, "Yes, which is why I came to see you. I want to know the whole truth about what happened back then. I hope you can tell me everything about what I'm looking for, Uncle Tang."
"You're suspecting that my elder brother's death has to do with what happened back then." As a businessman, he couldn't possibly fail to connect such simple dots.
Combining what Mu Lin was saying now with her previous questions, Tang Qishan could entirely tell; she simply didn't believe his elder brother would do such a thing, which was very comforting.
Good! Excellent!
