Lin Wei, a modern girl, travels through time with the "Palace Fighting Assistance System" and is forced to assist the cold-faced fourth prince Xie Yan in seizing the throne. After the mission was successful, she was eager to return home, but was forced to stay because of the emperor's paranoid love. When she activated the system and returned to modern times, Xie Yan became pregnant unexpectedly and followed her. The collision of two worlds and two rules begins an epic about love, freedom, responsibility and growth.
