Lin Qingyu, the astronomical master, was framed and exiled to Yazhou. His whole family was imprisoned and everyone was destroyed. With no hope left, he was about to commit suicide by throwing himself into the sea when he heard the cry of a baby. The infant child was on the ice in the sea. Lin Qingyu chose to live with the hope of her child and life.
As Lin Pingan grew up day by day, when she was 8 years old, her adoptive father Lin Qingyu was killed by an assassin while she was fishing in the sea. Lin Pingan began his journey north to find out the truth of the matter. From the small fishing village to the capital, she met many people and unfolded various strange stories, but she never gave up seeking the truth. Finally, she entered the palace and became the envoy of the Shangshi Bureau, but there happened to be a severe drought. The day of prayer set by the Qintian Prison had no effect, and the emperor was furious. However, Lin Ping'an cleverly solved the problem by using the mysteries of celestial phenomena and officially entered the Qintian Prison. As he continues to get closer to the truth, he also continues to witness the sadness in the imperial city.
Lin Ping'an's astronomical skills were feared by others and he was framed as an ominous blade. Jian Zheng insists that only by offering sacrifices to the gods can the world be peaceful, and uses strange celestial phenomena to further intimidate. On the day of the fire sacrifice to Lin Pingan, the sun was shining brightly and the fire kept approaching, but Lin Pingan did not give up. She tore off her dress and wrapped it around her mouth and nose in a final attempt to save herself.
Lin Ping'an regained his vitality and turned from an unknown lonely evil spirit into a saintly girl who was spread by word of mouth. She also finally learned the truth about her adoptive father's murder. The former harem was intertwined with each other, and the late emperor who had given the order to silence him was already dead. In a dark and windy night, Lin Pingan sneaked into the imperial mausoleum, and the entire underground palace was set on fire and disappeared into smoke.
A few years later, on a fishing boat on the beach, Lin Ping'an set up his fishing net and quietly looked at the sky in the distance.
