Former comic editor Su Chen used a mysterious system called "Magic Pen" to travel back to the post-apocalyptic comic "Rust Era" where he was cut in half. The system told him that as long as he collected the "most touching stories" in the world, he could get points and redeem them for everything. So, in this wasteland where everyone is struggling to survive, a strange store opened. Its sign is crooked, there is no food or water on the shelves, only blank drawing paper and pen and ink. The "currency" it collects is stories, and the "remuneration" it pays is to allow everything in the story to briefly become reality.
