The Qimen has been lost for a long time, and Dunjia has disappeared. Who can control Yin and Yang? Who can take advantage? The abandoned baby in Gujing, is it a boy or a girl? And who saved it? Is the acquaintance between a young man from an aristocratic family and a beggar girl an act of God or man-made? Can the rebellious daughter return home? The Emperor Star wanders among the people, a pursuit and encounter across time and space, two romances, four separations of life and death, and the cause and effect is difficult to find. This is not a pseudo-fairy tale of consensual love and a perfect match. This is a fight against destiny, daring to fight against heaven, and fighting for it despite knowing that it cannot be done. Traveling through four hundred years of entangled love and hate, the love is no match for its passing time. Who will lose and who will win will not be known until the last moment.
