At this point in time, it was all or nothing for Mark. As for the CCTV cameras that Ling Tianya was talking about, he could easily swap out the tapes when their leader wasn't around. He could secretly destroy the footage.
And he didn't like Ghost Charm much anyway, so he could just kill them both together. She was intoxicated right now anyway, locked up in the storeroom.
"Mandy is right, killing you is the only solution to everything right now! As for Ghost Charm, she wouldn't have the ability to come to your rescue. I injected her with anesthetic and locked her up in the storeroom."
"Hahaha!" Mandy was laughing hysterically. "Young Mistress, it seems like no one will come to your rescue this time. No one will hear your desperate cries. I am going to pay back all the pain I had to go through because of you. I'm going to return it to you ten-fold! All the pain you're going to experience is just proof as to how much I hate you!"
