What Is the Beginning? the System and I Were Opened by the Heroine.

Shen Su traveled through time. Going back to the novel I read in college, I remember that the heroine is Dan Xi, and everyone in the novel died in the ending. He thought he was a prophet, holding a script and a system that could change everything. Then he met Danxi. In thirty minutes, she revealed his identity as a time traveler, made fun of the way he was killed by a stock speculator who jumped off a building, and unboxed his system - "Developer backend, gear icon, third level permissions. I see you." The system was silent for a moment, and a prompt popped up: It is recommended to eat soft rice. Shen Su asked seriously: "Can I eat soft rice?" Dan Xi smiled: "Okay. Take care of yourself." ——But Shen Su has read the original script, and there is no character "Shen Su" in it. So how did she know him? Who is she? Etc! Original version?
