Enigma05:
Does elder sis tell ZY she saw him killing Wuji? Maybe Wuji was expendable to him from the get go. But he's obviously mentally screwed up and lord knows who's side he's on.
I don't know...that has not been leaked yet. Hopefully, she tells him...As for him and Wuji...I'm still confused about that...and yeah he does.
Do you remember when GZS and JF were investigating and found out about the boy who used to be sick and suddenly got stronger? I saw a theory somewhere that GHY tested out medicines on that boy to use for his plans...
