Chef Supreme said that because he was trying to give the Mirror God, God of Fools, and the rest of the Freedom Federation a chance.
If the Freedom Federation persisted in attacking despite the significant sacrifices made by the Radiance Federation on their behalf, they would deserve to be conquered by the Radiance Federation. This would result from their breaking of the initial agreement, thereby compelling the Radiance Federation to respond with a counterattack.
Iron Prison knew he was not skilled at acting, so he did not say anything and allowed Chef Supreme to steer the show.
The Mirror God and God of Fools were delighted by the answer. Chef Supreme and Iron Prison had really managed to help the Freedom Federation to obtain a year of time!
