After a long while, when the disciples had exchanged information for an extended period and had roughly understood the other participants in the trial, the ones who eventually returned to the Sect immediately regretted their decisions.
Among these disciples, a few had actually obtained some information in the Otherworld initially, but they felt it was not enough to stand out among the many disciples participating in the trial. Desiring greater recognition and rewards, they delayed until the very last moment in hopes of gathering more intelligence.
Little did they know that the information they could obtain was also accessible to others, and because they returned late, they ended up with nothing.
Moreover, such cases were not isolated; similar instances existed across the Sects of the Five Domains, otherwise Mituom Buddha wouldn't have been able to retrieve so many people from the Otherworld.
