The janitor's reaction was within Yang Yi's expectations. If they wanted to make a big deal out of this, then the janitor would have to buy the intelligence, because cooperation is cooperation, but the money that should be paid can't be less. Without evidence, the janitor leaking anything independently of the Organization of Water was meaningless, unless they had found evidence themselves.
However, the janitor would definitely not act without the Organization of Water; doing so would destroy the organization's business. Even if the janitor was tight on funds, they would never engage in such self-destructive actions.
Yang Yi hung up the phone and then pondered how to maximize his benefits from this situation, while also ensuring that the Organization of Water faced no danger.
