During a fission chain reaction, the correct fact is: The number of freely-moving neutrons increases over time.
In a fission reaction, when an atomic nucleus splits, it releases neutrons. These emitted neutrons can then induce further fission reactions in nearby nuclei, leading to a chain reaction. Therefore, as the reaction proceeds, the number of neutrons available to continue the process increases, at least initially.
