Chopper spoke up at this point. "Seeing such a tragic sight, we wanted to do something for them right away, but the remaining gas was dangerous to us too, so we left the town first."
Luffy sat on Duke Quannan and said, "So that's how it was."
Everyone looked at Duke Quannan, and the entire place fell silent as they recalled Zou from ten days ago.
"How did things become this disastrous? The entire country is covered in poisonous gas. Chopper, do you have any good ideas?" Sanji asked Chopper.
