Guyue Villa was brutally wiped out overnight. The raging fire devoured a century-old foundation and destroyed the peaceful and carefree life of the young owner Shen Jinghan. At the age of thirteen, he managed to survive this catastrophe. The black iron token of his father, "Leng Yue Sword Immortal" Shen Canglan, became his only thought and symbol of identity, and it also made him shoulder the heavy mission of finding the truth and avenging his family.
On the way to escape, he met Su Muyan, a girl with a mysterious identity. On the surface, she is the caretaker of the villa's medicine garden, but in fact she has special skills, agile and quick sword skills, and knows how to use herbs to prevent poisons. It was due to Su Muyan's help that Shen Jinghan was able to escape from danger many times during numerous pursuits. The "Star Observing Mirror" that Su Muyan was entrusted by the third elder to keep, a bronze mirror full of cracks and engraved with star maps, hides the unknown secrets of Guyue Villa, and also closely connects the fate of the two.
Behind the massacre was the conspiracy of the "Blood Moon Oath", the rebellion of the second elder, and the disputes in the world caused by the "Yue Po", the treasure of Guyue Villa's sect. Shen Jinghan took the black iron token left by his father and the turquoise dagger given by Su Muyan, and embarked on the journey with Su Muyan, who was wounded by an arrow and whose life experience was a mystery. They want to go to the Yanyu Tower to search for clues, uncover the secret of the "Star Observation Mirror" on the night of the blood moon, let the "Yue Soul" find its true owner, and let the innocent souls of Guyue Villa rest in peace.
