Everyone believed Fairy Su Ran was the gentlest person in the world. She always greeted everyone with a warm smile. But they didn't know that Su Ran's soul had long ago been replaced by a demon from hell: her twin sister, Su Ye.
Su Ran was hopelessly lovesick. Even after her family was destroyed, she still played the wicked female supporting character who sabotaged the romance between the male and female leads. Su Ye was reborn, but her sister was still beyond saving, so she decided to take over her body.
The transmigrator had five spiritual roots, yet became the heroine thanks to a System. She stole the fiance who should have belonged to Su Ran and took her spiritual roots, so Su Ye would take the transmigrator's System.
With Su Ye's forceful arrival, the course of events on the Tianyuan Continent, which was originally a storybook world, was completely turned around. But wasn't Su Ye, the one who changed everything, also a chess piece being moved by someone else?
