That night, what Liu Xia Fang dyed was not cloth, but blood.
Nine-year-old Lin Xi held hands with five-year-old Lin Zhao and crawled back to earth from hell. Ten years later, one of them became the "poison doctor" who saw the evil in people's hearts, and the other became the "firefly" who purified the filth in the world.
Ku Rong Gu Dao, one body with two sides. It can both save people and destroy the world. The blood-stained enemies of the past are now in high positions of power and regard all living beings as pawns.
They forget that those who come back from hell are never human beings. They are the ghosts who come to seek their lives!
