In the autumn of 1938, the Battle of Wuhan was in full swing. Ting Hua, a military commander codenamed "Qingming", was ordered to sneak into Japanese-occupied areas to carry out a top-secret mission. However, he soon discovered that he was facing not only the pursuit of Japan's special high school, but also an even stranger existence - every full moon night, the Japanese army's swordsman masters could turn into bloodthirsty ghosts, invulnerable to weapons and weapons, and kill people invisible.
What is even more puzzling is that all clues point to an ancient Japanese swordsmanship school-"Mingshin-ryu". This sect has been passed down for three hundred years, and each generation of sect masters has mastered a secret technique: practicing swordsmanship to the extreme, nourishing ghosts with murderous intent, and nourishing swords with ghost energy. Tinghua's real mission is to find and destroy the center of Mingxinliu and break this curse.
In the process of tracking, Tinghua constantly encounters the core members of Mingxinliu - everyone has a story of blood feud, and everyone is struggling between light and darkness. Tinghua was forced to use the means of an agent to infiltrate, instigate rebellion, and attack these people, turning them from enemies into allies, or at least into pawns.
Amidst the flash of swords and shadows, Tinghua discovered that his life experience was also related to this - his grandfather had a decisive battle with the first generation master of Mingshin Ryu in Japan and sealed that power. Now that the seal is loose, only Tinghua's bloodline can seal it again. But this requires him to pay a price: the moment the seal is completed, he himself will be drawn into endless darkness.
The suspense progresses layer by layer, and the espionage battles are intertwined. Tinghua constantly makes choices between humans and ghosts, good and evil, loyalty and betrayal. When the truth gradually emerged, he realized that the real enemy was not Mingxinliu, but the unfulfilled desire deep in the human heart.
