The Side Character Only Wants to Survive to the End

[Transmigrate into a book + reborn + cultivate, fight monsters, and ascend]

Lu Xiyu had no idea why her best friend had insisted that she transmigrate into a book. And now she was stuck in a useless sect. No one was allowed to slack off. Before long, the sect was thriving again and no longer useless. But everyone still thought Lu Xiyu was a burden, and, assuming she would look down on them someday, they told her to leave the sect. That was no challenge for Lu Xiyu, though. In the end, she would become the strongest Immortal Venerable in the cultivation world.
