How to set a long story you've written on fire

There are a lot of factors that can make a reader feel a sense of immersion in an article, such as writing, plot, innovation, etc. But I personally feel that, while the other parts of the article are still good, it's especially important to control and adjust the overall rhythm, and what is the rhythm of the article? Let's put it this way, let's assume that you're on the road right now and you've planted a landmine and want to blow up your enemy, C, similar to the following picture.

And you're hiding behind a wall. Your enemy doesn't know you're hiding there, but you can see him slowly approaching, and soon he'll step on the mine and blow himself to pieces, and then you can pack up and run.

Say your enemy C is now 1 away from the mine, but then your girlfriend G shows up on the other side of the road. It is also heading in the direction of the mine.

MMP, you haven't rolled with her yet! How can you let her die just like that?

So now the story is entering its climax, because the reader is in an unpredictable panic about what's to come, the story is closed, and the reader will desperately want to know what's going to happen down the line, and the first step in writing a text that creates a desire in the reader and retains the reader is realized for the time being.

The so-called "adjusting the rhythm" is actually adjusting the distance between C and G and the mines.

With two people at about the same pace, if C and G are far apart, you have two slow strategies - one is to talk your girlfriend away from the enemy's field of vision, and the other is to have the enemy step on the bomb when your girlfriend is still out of safety range - which will result in a very soft narrative.

But fuck if C and G are close and both a few steps away from stepping on a landmine, the pace picks up all of a sudden, and you have to immediately step out from behind a wall and then stump your girlfriend, at which point the pace is significantly faster than the last.

There's also a fucking extreme case.

Just as you're about to get the fuck up, suddenly there's a DUI car behind your girlfriend, or a bus running a red light to your side, or maybe it's suddenly thundering and raining in the sky and your girlfriend quickly runs forward to get out of the rain.

Your rhythm is definitely like riding a rocket.

So pacing is all about adjusting the pace of your story to what you want it to be, by controlling the relationship between "reader expectations" and "plot setting" when you can dictate the reader's emotions (tense or otherwise).

That's all I can say for now, given my limited space and writing skills.
