Just as Mary predicted, the person did not intend to let Mark go.
Mary frowned and said, "How can you go back on your word? My boss has already discovered that the seal has been lost. Now that I can't steal anything else for you, she definitely won't let me off. She might have already called the police! As long as you let my brother go, I'll stop contacting you. You won't be implicated…"
"Miss Mary." The man in black interrupted Mary. "It's precisely because we won't let your brother go that you must bear the responsibility yourself. If we let him go, you won't have any worries and you'll cooperate with the police investigation and betray us. Don't worry, as long as you're obedient, I won't hurt your brother. However, if you have any ill intentions, I'm sorry."
