Earning Points in the Cultivation World

Please Help Me Find a Cultivation Novel

Because of the original female lead, who's a scheming innocent, the heroine leaves her old sect and joins a new one as its junior sister. She keeps helping her new sect's senior brothers win the sect tournament. In one event, all the direct disciples end up in a mud pit, like that Running Man game where you have to stand on a platform in the mud when the music stops.
