Green Bamboo and Black Bamboo are originally two green and black snakes that have been practicing for thousands of years. In order to refine their demonic power and absorb pure yang energy in order to pursue the great road, they transformed into twins and stepped into the mortal world.
On one side is the fate of demons seeking Taoism and inseparable from pure Yang essence; on the other side is the heartbeat and fetters brought by the good intentions of the world; on the other side, they have to absorb the Yang essence of evil people to enter the Taoism; on the other side, they need to accumulate virtue and do good deeds to offset their debts; on the other side, there is the emotional Buddhist monk who abides by the rules and regulations; on the other side, there are the rebels in troubled times who are ambitious, bloodthirsty and cruel. Qingzhu is calm and restrained, focusing on balancing practice and cause and effect; Mozhu is simple and straightforward, and can't hide his desire for pure Yang energy. The love debt between the two sisters will never be repaid.
The confrontation between humans and monsters, the intertwining of good and evil, the disputes in troubled times, and the catastrophe of love. A pair of twin snake sisters wander between good and evil, making step-by-step choices among desire, morality, love and the great road, composing a record of spiritual practice in the world that is both evil and good, half turbid and half pure.
