Soul Eater of Immortals

A baby was born in a village with a soul-eating bead in his body. That night, the family was killed by the demons and the baby was taken away. The baby was named the demon youth: Nie Yifan. A few years later, Demon Lord She Yu told Nie Yifan that he was not his parents, but that his parents were killed by the Zhu Xian Sect, and ordered him to go to the Zhu Xian Sect to avenge his parents. In the Zhu Xian Sect, Nie Yifan fell in love with Wu Guan Wan Ning, the daughter of the Zhu Xian Sect's supreme official Yun Lei, and overcame many difficulties and obstacles to finally become the only strong man in the world: the Soul Eater.
