Yanhe entered the "Expired Cannery" instance for the first time. He used the ultraviolet lamps and sealed raincoats he had hoarded to escape the corrosive fog, and bribed experienced players with unexpired cans to obtain clues to the rules, and passed the level in the first battle. After that, she made precise use of the system space: using the mechanical parts stored in the "Clock Cemetery" to quickly repair clocks, and using a portable recorder to record coded lines in the "Echo Theater". On the way, she refused the requests for supplies from her "Notre Dame teammates" but distributed compressed biscuits to the injured little girl. As the difficulty of the dungeon escalated, she discovered that there was a secret of "layer space" hidden behind the conspiracy, and the "old calendar" she had hoarded could predict changes in the dungeon rules. In the end, with a warehouse full of supplies as her confidence, she led a few survivors to challenge the core of the conspiracy.
