The time-traveler Jiang Yuwei needs a phoenix seal to survive due to radiation. After seeing the tragic death of the time-traveling woman in the palace, she lies dormant in the cold palace and pretends to protect herself, relying on Feng Shui techniques to take care of the deceased. She saw through the game conspiracy between the emperor and the imperial advisor, used Feng Shui to get rid of the imperial advisor, and tricked the greedy emperor into traveling to modern times. In the end, she took control of the court with the phoenix seal in her hand, rescued the pregnant woman who time-traveled, supported the new emperor and the posthumous son, and used her immortality to control the situation behind the scenes, pushing this era towards a new order of equality between men and women.
