The story takes place in the world of immortality where the rules of time and talismans are manifested. When the protagonist Han Minglang was eighty-one years old, he was abducted by the Pure Blood Society because he had a rare "Yin-Yang Harmony Body" and was forced to practice the "Yin-Yang Tonic Art" to become a furnace. In the midst of humiliation and despair, he unexpectedly glimpsed the fragments of "Xinghe Hanging Jue". Combining his profound understanding of yin and yang, he went in the opposite direction and reversed the tonic method into the "yin and yang transfer method" - instead of robbing others, he used himself as a bridge to mediate and ease the conflict between yin and yang and the five elements in others, helping them break through bottlenecks. As a result, he got acquainted with Su Wanqing, a mixed-race monk who had difficulty practicing due to his impure blood, and Lu Wuya, a demon monk who was exiled by his sect due to conflicting ideas. The three of them traveled together between the time gap and the world of talismans. Han Minglang accumulated merit and enlightenment by helping others practice, and his cultivation improved slowly but steadily. They are gradually involved in the pure-blood society's conspiracy to wipe out mixed-race descendants, and encounter constant provocations from the "Tao Heart Torturer", forcing them to re-examine their own practice concepts. In the end, Han Minglang relied on the "Xuantian Treasure Mirror" to see his own cause and effect, clearly understood that "helping others is to save oneself", understood the "unmatched true meaning" at the source of time, used the Tai Chi body to carry the yin and yang and the five elements wheel, achieved the Dharma Cloud Land, disintegrated the extreme ideas of the Pure Blood Society, and opened up a new path for the world of immortality that focuses on the cultivation of mind and is inclusive.
