Su Li, the founder of ancient metaphysics, died from exhaustion in a battle with foreign demons. He accidentally traveled to modern times and possessed Gu Nianzhi, the real daughter of the wealthy Gu family who had just been found after being lost. The original owner, Gu Nianzhi, grew up in an ordinary family. After returning home, he was made things difficult by the fake daughter Gu Yaqin and others.
After rebirth, Su Li relied on her profound knowledge of metaphysics to see through yin and yang at a glance, and was able to subdue demons and eliminate demons. She was even more proficient in reading faces and divination. By chance, she started a live broadcast of fortune telling, accurately predicting the fate of test takers, and quickly became popular on the Internet, gaining a large number of fans. At the same time, she used metaphysics to help the Gu family resolve many crises, and gradually gained recognition from her family.
At school, Su Li met Shen Yichen, the aloof academic tyrant. Shen Yichen possesses a mysterious purple energy that can deter evil spirits, but it also attracts the covetousness of dark forces. Su Li joins hands with him to explore the secret of purple energy and fight against the darkness. As for the King of Yama who was far away in the underworld, as Su Li's junior brother in his previous life, he secretly helped after learning that his senior sister was reborn.
In the modern era where technology and metaphysics coexist, Su Li is adapting to a new identity and cultivating relationships with her four brothers, while using metaphysics to punish evil and promote good, and solve supernatural incidents. In the end, she became a legend in the metaphysical world, gained sweet love with Shen Yichen, and lived a happy life.
