Lin Yuan was born into a poor family. In her previous life, her eldest sister Lin Yunshang took her engagement away from her because of her humble family background. She married a sickly prince and eventually died in depression. After her rebirth, she unexpectedly obtained the ancient bloodline - "Qingluan Spirit Body", which allowed her to briefly transform into a phoenix on a full moon night and control the power of wind and thunder. However, her rebirth is not an accident, but a "system task" in the world of the book: the original owner must complete the "substitute marriage" plot to unlock the next main chapter. But Lin Yuan no longer wanted to be a chess piece, so she teamed up with her sister Lin Yunshang, who was also reborn. The two pretended to conspire, but in fact they secretly planned it: Lin Yuan sneaked into the imperial city as a substitute bride and used her powers to see through the court's conspiracy; Lin Yunshang disguised herself as a weak concubine and quietly spread the power among the people. As the two men rose in power, they discovered that the so-called "substitute marriage" was actually a trap set up by the former court's ministers, who intended to restore the old system with the help of women. From the beginning, Lin Yuan just wanted to survive, to taking the initiative to expose the corruption of the court, breaking the shackles of gender, and even led the women at the bottom to establish a "female workshop", becoming the first female leader with an independent economic system. The arc of her growth lies in her transition from passively accepting fate to actively reshaping the rules, and finally ascends to a high position in the court as "neither a man nor a woman", breaking the shackles of thousands of years of ethics.
