How to get out of icing conditions asap?
well, you'd have to fly in whatever is the shortest route out of the icing conditions, obviously.
What that would be depends on your speed, wind, climb/descent performance, and how you entered icing conditions.
If you entered icing by climbing, diving may well get you out of it (but if you were climbing to avoid terrain...).
If you were turning left, turning right might do it (but were you turning left to avoid collisions?).
Etc. Etc.
IOW there's no universal answer, it's way too situational.
