Lin Zhao was adopted by the Yin Temple since he was a child. He was born with a strange ghost mark on his left arm and could see the souls of the dead that ordinary people could not detect. He thought he was just an abandoned orphan, but he didn't know that from birth, he had been involved in a process of sacrifice and redemption that lasted for twenty years. Bai Mingshuang, a woman in red who suddenly appeared in the temple, holding a copper bell, led him step by step to uncover the dust-laden truth: back then, the Yin Temple sacrificed seven virgins alive to suppress evil spirits, and he was the only "gatekeeper" who survived that ceremony. Bai Mingshuang's true identity is the remnant soul of the seventh virgin who died that year, and the survivor that his father desperately saved. As the dead souls awakened and the Yin Temple moved, the dust-laden secrets were revealed layer by layer. Only then did Lin Zhao realize that he was not abandoned, but protected; not used, but waited for. He must make a choice between fate and redemption, whether to repeat the sacrifice of the past, or to single-handedly break the curse of the Yin Temple that has lasted for twenty years. When the bell rings and the dead soul returns to his place, his and her fate have been tightly tied together from the moment of birth.
