If the entire value of an item of writing hinges on the revelation of a single fact, then the writing is flawed.
State the fact and be done with it.
(As I've just done here.)
If the writing has value, the fact will be immaterial to that value, and the true reward for the reader is in the telling of the story, the narrative developed, the introduction and interrelation of facts, concepts, characters, strengths, and flaws. And yes, telling those, where they are material to the story, takes time, but also is its own constant reward.
We have classics of literature and mythology. The stories are well known. The boy loses the girl, then wins her back. The dog dies. We all die. A tree grows in Brooklyn. George slays the dragon. Cinderella wins the prince. The Wicked Witch is overcome. Jesus dies, then returns. Buddha is enlightened.
Those facts don't matter to the value of the story. It's the details built up along the way, the morals and principles exposed, which do.
Build your stories around those, then pull away all that truly does not matter.
(This sounds simple. It's much harder than it seems.)
