The entire story strictly follows the original plot of the Flower Angel animated series. A web novelist who died from overwork in her previous life transmigrates to the continent of Labelle and becomes Kuku Li, the younger sister of Kuku Lu, the sole prince of the Ancient Spirit Fairy Clan. Her human alias is Gu Li. Just as the Dark Goddess Yaga steals the Flower Codex, the Goddess Pupu La orders Kuku Li to go to Earth too. But Kuku Li is determined not to get caught up in the rat race this time. She awakens the “Lie Flat Sign-in System,” which grants her experience and god-tier rewards whenever she “watches from the sidelines” or “sleeps” at key points in the plot. Starting with the recovery of Chun, she watches Xia An'an and her brother get into trouble and suffer, while she sips milk tea nearby and levels up. As the story progresses, from life on Earth in the first season to the later Palani and Four Seasons Clock arcs, her cultivation breaks through the heavens at a bizarre pace, from magic apprentice to the Final God. Whenever the main cast faces a desperate situation, all she has to do is yawn and release a little pressure, or let the System defend automatically, to resolve the crisis. Yet she is always mistaken for someone with unfathomably deep schemes. This is a story about “you work hard to save the world, while I lie flat and watch the show,” and somehow end up invincible.
