Deep in the mountains of southern Guizhou, Guilan, the Shui, Miao and Buyi people have coexisted for generations. The ancestors of the three tribes used the eternal sacred stone as the foundation, laid earth vein seals to suppress the underground dark spirits, and established a covenant to guard the mountain for generations. Fireworks and peace have been peaceful for thousands of years. The world thinks that guarding the mountain is the supreme glory, but little does it know that the saying "Those who guard the mountain are all prisoners" hides the shackles of eternal fate.
Frost and mist appeared out of thin air, and the living fog blocked hundreds of miles of mountains. The underground dark spirit leaked out through the turbid air. Fifty-six young people who inherited the water book, Miao Gu, Zhiwen, Bayin, Lingcao, and patrolled the six great traditions simultaneously fell into the same dream of doomsday, and the catastrophe began. This group of teenagers formed a Tao-keeping Alliance of fifty-six people, with the Five Saints Meng Bufan, Meng Xiaohe, Chi Luo, Luo Yin, and Lingxi as the core. At first, people were confused and each had their own obsessions. Suspicion and estrangement almost broke up the alliance. However, through the experience of exploring cracks, resisting shadows, and facing their inner demons time and time again, they got to know each other, put aside their personal grudges, and made a pact to work together to realize the Tao.
The Dark Spirit Tribulation is just the beginning of the test. When the mountains and rivers are temporarily settled, the Heavenly Dao scam that has been dormant for eternity slowly emerges: Heavenly Dao has laid down the shackles of reincarnation in order to control the paths of all living beings, using the ninth generation of martyrs to restrain the hearts of mortals, fearing that the path of symbiosis in the world will transcend the established rules. At the same time, the Nirvana void outside the territory quietly peeks into the mortal world. The creatures in the void are bound by Nirvana's obsession and regard life as their enemy. Two powerful enemies attack from the front and back. The young boy from Guilan is forced to embark on the path to enlightenment against heaven.
From a small tribulation in the mountains to the game of the three realms, fifty-six young people have experienced dream trials, bloody battles across the world, enlightenment in secret realms, and punishments from heaven. They have sharpened their hearts in desperate situations time and time again, solved the fateful dilemma of "guarding the mountain as a prisoner", and will not compromise with the rigid way of heaven.
