[Spiritual qi revival + revenge + a killing spree + high-martial-arts urban fantasy]
A century ago, spiritual qi revival swept the world. Demonic beasts ran rampant, and humanity stood on the brink of annihilation.
The Sword God Liu Xuan appeared out of nowhere. With nothing but his sword, he carved out a hundred years of peace for humanity and was revered as the “Guardian Deity of the Nation.”
But his achievements eclipsed the throne. After he was gravely wounded suppressing the nation’s fortune through its dragon vein and entered a deathly seclusion,
the five great martial families he had personally supported stole his accomplishments, erased his existence, and slandered him as a “traitor to humanity.”
A century later, his only descendant, his prodigy granddaughter Liu Shiyu, was framed by the five families for colluding with the demon race.
At the Dragon Kingdom’s Heaven-Worshipping Ceremony, broadcast live to the entire world, her bloodline was stripped away and she was tortured to death!
At the instant her life force was extinguished, the Dragon Kingdom’s forbidden ground, the “Sword Mound,” exploded. A man dressed in ancient white robes slowly emerged.
That day, at last, the world remembered the fear it had forgotten for a hundred years.
“I guarded this mortal world for a century, and you killed my granddaughter?”
It's too messy; the relationships between the people are unclear.
He can manipulate cause and effect but can't resurrect his granddaughter, and his daughter-in-law is now his enemy. The relationship is so confusing, switching between ambiguity and hatred all at once.
