In the prosperous Tang Dynasty, Taoism and Buddhism coexisted, Dharma and Confucianism were selfless, and heretics would do anything to seek longevity. Liang Jiunan was reincarnated and entered the Demon-Conquering Division. He obtained the "Tai Sui Picture" and was taught the seven-star technique to conquer demons. He was trapped in the conspiracy of immortality.
However, along the way, he repeatedly solved strange cases and experienced three disasters and nine disasters. Looking back, he saw that it was a mountain of corpses and a sea of blood, and things and people had changed.
Liang Jiunan raised his eyes to look at the sky and finally swore: "I don't seek immortality, but I will achieve it after all."
"From now on, my sword will bring peace to the country and protect the peace of all living beings."
