I just read it and I think the 2nd part that I said is the most reasonable answer.At chapter 1, she died and the scene was at the morgue of the hospital. Now, looked at the chapter 2. Before she was reborn, there's a line there saying,"a huge vortex twisted everything to its center and countless memory fragments instantaneously swept through Su Yayan's mind, one by one."It's easy to misunderstand that sentence simply because of a lack of details and most people would probably think that what she receive is the info about the system, but I'll explain it later in the way I understood it so I'll point out some important points first.After she was reborn, she became a host of a system and at chapter 3, it was explained that she is just a story in a book, which she actually accepted calmly.At chapter 4, it was said she is just a cannon fodder and the main character of the book is her fiance and the btch that pushed her to death. There's also a line there saying,"but after you died, the expendable youngest uncle of the Huo family, who was supposed to die, work against the natural law and order. He killed the male and female main characters, causing the whole world to collapse, that is why you are given this chance to start over."Now let's go back to the first line I shared.Based on the clues, the original timeline was destroyed because of that youngest uncle and by that, we can say that when he made the decision to kill the main characters(which is the scene in the morgue before Su Yayan was reborn), it was the turning point of the story on which the world immediately collapse and the countless memory fragments that Su Yayan received is about the future 'her' that is following that youngest uncle.We can say here that she still receive those future memories for unknown reason but with the clues that was hidden in the story, this is what I think the possible answer to this messed up start of this story.Ignore the first reply I shared.
