Realizing there might be attack effects he couldn't detect, Su Yu hurriedly checked his Book of Narrative again, focusing on his own story.
There still didn't seem to be any issues; all the stories appeared normal, with no sudden emergence of text or paragraphs.
Su Yu was most worried about the unknown attack modifying his past story.
Such a modification is not on a timeline level.
Simply changing the timeline means nothing to Su Yu now.
For instance, modifying the past timeline to make Su Yu die just as he crossed over to Azure Star; in that case, it seems like Su Yu is doomed, never existing from the start.
But this is merely "non-existence" on a timeline level.
On the Book of Narrative, the essence of this modification is adding a new chapter to the end of the existing story.
The content being "the timeline was modified, Su Yu died at the beginning of his crossing."
Essentially, such modifications have no impact on the stories that have already occurred.
