The centenary old Taoist "Xu Junxiao" was picked up by three senior brothers a hundred years ago. The master gave each of the four senior brothers a piece of immortality. Later, the senior brothers went down the mountain to fight against the Japanese and never returned. One day, an enemy brought the immortality energy of the three senior brothers and possessed Bai Yueguang Xiaoxue in an attempt to steal the last immortality energy from Xu Junxiao. Unexpectedly, Xiaoxue seriously injured him with the soul-suppressing talisman left by his master, and sacrificed his life to return the immortality energy of the three senior brothers to Xu Junxiao. From then on, Xu Junxiao began a century-long journey of investigating and finding the murderer. In the first hundred years, Lu Wanwan, a rich girl with ulterior motives, appeared with clues, and together with Xu Junxiao, they gradually uncovered the century-old mystery.
