A Side Character's Path to Immortality

Wei Zhiruo suddenly woke up in a new world.
Here the Dao seekers were rushing to seek immortality, practicing day and night to grow stronger and fiercer! For her it wasn't enough to embrace cultivation, but survival meant reinterpreting everything she was familiar with. She strived ahead like a fish in the waters, getting familiar with this world's blue skies, its lilac flower fields, forging her own path ahead.
But in the midst of such struggles, she often came across strange people...
One day, she finally understood why. Wei Zhiruo hadn't just reincarnated into a simple world of cultivation! Here, in some people's mind, the life of everyone else was just an insignificant part of a book, including that of hers! What about 'Heaven's Chosen One's', 'Book-Transmigrators', 'Reborn people who were adamant on changing their past life's mistakes' - she often met such mysterious people and was often forced to play a side character inside these people's tales of grandeur!
The only way out - gather strength and become invincible!
This is the story of how Wei Zhiruo changed her side-character aura, becoming the most powerful Immortal in the Immortal Realms, and how she overturned a million years old conspiracy lurking in the shadows of Cultivation world!
