The Legend of Xiuling Valley

Yuze and Nanfeng are two disciples of Hongshi Tianzun. On their way back from exterminating a demon, the two of them coincidentally entered the secret realm left over from the Six Realms War ten thousand years ago. In the secret realm, Nanfeng obtained a weapon from the ancient god of war, the Tiangang Eighteen Halberd, while Yuze obtained a snake egg that had been sealed for tens of thousands of years. Because the snake egg was sealed in the dark for a long time, its spiritual energy was almost completely lost. Yuze couldn't bear to lose it, so after many twists and turns with his senior brother Nanfeng, he finally obtained the fortune-telling grass and successfully awakened the young snake. After the baby snake was born, he became a disciple of Yuze. She was around his master every day, adding a lot of comfort to his unfortunate childhood. Later, when they were playing in the human world, the young snake was unfortunately captured by a fox demon and imprisoned in an ice cellar. His life and death were uncertain for a time. Yuze lit nine ever-burning lamps for his disciple. When the last ever-burning lamp went out, his mood hit rock bottom. In order to save his disciple, he spent his entire life cultivating himself and lit the last ever-burning lamp for her. Later, in order to save Yuze, his senior brother Nanfeng escorted him to the lower world for reincarnation several times. In the end, Yu Ze and his disciple finally met each other after seven lives and thirteen tribulations, but the fate failed and the three of them ended up injured, one died and the other became possessed.
