Shen Yan, the proud disciple of the Righteous Sect, is actually the orphan of the Demon Sect's "Shadow Pavilion", and he also bears the secret order to awaken the Demon Lord's remnant soul. When the sect was encircling and suppressing the remaining members of the Demon Sect, he accidentally discovered that the Ying Pavilion's destruction of the sect was a conspiracy set by Zhengdao. On one side is the sect's upbringing, and on the other side is the mission of his bloodline. He relied on the good and evil techniques to overcome many crises, find out the truth, and finally break the barriers between good and evil, and find a path to subvert the structure of the martial arts world.
