The blood moon is in the sky, and monsters are rampant. Qinghe, a cynical little Taoist priest, was ordered to go down the mountain and team up with the upright policeman Wang Zhiliang to uncover the Nether Sect's shocking conspiracy to open the "Road to Heaven" with the blood sacrifice of all souls. When saving the common people requires paying a price for loved ones, when the morality of guardianship is tainted by the intrigues of the court, when the survival of the world faces a cold "ultimate evaluation"——
Two mortals, passed down for three generations, wrote a tragic song about sacrifice, inheritance and choice under the bloody moonlight.
This is not only a story about slaying demons, but also the ultimate question of "Where is the Tao?": On the mountain? In the court? In an earth-shattering spell? Perhaps, the answer lies in every choice made by ordinary people despite knowing the difficulties but still moving forward.
