Leng Ye was originally the surviving son of Demon Domain Lord Cang Xuan and Tianmu Clan Saint Qing Yao. He struggled to survive in the Demon Domain Death Arena since he was a child. He was trained by the Demon Domain Lord as a double agent, lurking in the Heavenly Court Immortal Book Department, waiting for opportunities to pass on information and subvert Heavenly Court. However, after stepping into the Heavenly Court, he witnessed the fireworks of the Three Realms and the complex ecology of the Heavenly Court - there were corrupt officials and there were brothers (Zhao Tianba) and allies (Lin Xianer) who treated him sincerely. He also discovered that behind the "justice" promoted by the demons was the ambition of Cangyuan (his uncle) and the crisis of the destruction of the Three Realms. As the mystery of his life experience is revealed and the all-seeing eye of the Tianmu clan awakens, he gradually gets rid of his fate as a chess piece. While dealing with heaven, the demonic realm, and mysterious forces, he reveals the truth about his mother's death, prevents the opening of the Chaos Gate, and confronts the Lord of Shadow, the Lord of the Void and other terrifying existences. In the end, he transforms from a double agent into a key force to protect the peace between the immortal and demon worlds. He sticks to his true heart in crisis after crisis, and writes a legend that spans the immortals and demons, and combines the grievances and righteousness of the three realms.
