Nine Deaths and Immortals

"After I leave, open this jade slip." These are the words my mother said before she died. Ye Chen knelt in front of the grave for a whole day and night without crying. He stuffed the jade slip into his sleeve and walked into Qingyun Gate alone. Spiritual root test, five spiritual roots, inferior and inferior - everyone was laughing at him. Ye Chen didn't smile. On the night of my sixteenth birthday, the jade slip was finally opened. Inside is an ancient forbidden technique: "Nine Deaths and Immortality Technique". To practice it, you need to go through nine tribulations of life and death. Every time you survive a calamity, your strength doubles; if you fail to survive, your soul will be lost. The most suitable physique for this technique is the mixed spirit root. Deep in the mine, an old man who had been locked up for three hundred years accepted him as his disciple; the demon princess formed an alliance with him with a secret; in the sect competition, he risked his life to win the first place. But before he died, the old man told him: Your mother's death was related to Lu Ya, the head of Tianjian Sect. Ye Chen held the Cang Sheng Sword tightly and embarked on the road to Tianjian Sect. Is Lu Ya a benefactor or an enemy? How many of the nine tribulations of life and death can he survive? What is the truth behind the immortals in the spiritual world using the mortal world as a chessboard? Nine deaths, immortality, life towards death.
