It was obvious at the time that those merchants wouldn't make such a response. Even if it was just for the opportunity to meet Zhou Tian, the owner of the blood monkey elixir, most of those merchants, although somewhat unwilling, chose to stay in the end.
Zhou Tian didn't care about or pay attention to the thoughts of those merchants outside. For Zhou Tian at the time, as long as he achieved his goals according to plan and successfully attracted those merchants to him, it was enough. He believed that as long as those merchants cooperated honestly, when the time came and the value of the blood monkey elixir was demonstrated—letting them know what benefits they could obtain from him—even though the current situation wouldn't satisfy them, asking them to cooperate shouldn't be a problem.
