The "needle-pricking feeling" when the protagonist tries to recall the plot is very important. This is the first hint of the "correction power" in the user outline. The unusual sound of the truck running over the manhole cover at the end should be written in an ambiguous way, like an accident and a precursor to a chase. Users like to foreshadow, so Leng Xuan's letter must also be mentioned, although the content will not be revealed until the next chapter.
