[No heroine + cultivation + dark and brutal + no saintly do-gooding + stopping killing with killing + answering violence with violence + restoring order + reclaiming the laws of Heaven]
The early chapters are mostly setup. Later, the protagonist gradually grows into a ruthless man who lives only to kill. This blurb does a poor job of describing it, so please give the novel a read.
Bai Yi, the youngest prince of the dynasty.
As his eighteenth birthday approaches, a poison plot carefully disguised as an accident plunges him into eternal darkness, destroying both his eyes.
From the moment darkness descends, the emperor who sits high on the throne and the siblings who share his blood are, to him, nothing but beasts wearing human skin. He feels no kinship with them anymore.
In this world, all living beings are treated like sacrificial dogs.
Cultivators monopolize spiritual veins and hoard spiritual energy, treating commoners like ants as fertile fields crack and harvests fail;
The demon race throws the world into chaos and massacres humankind, while immortal sects look on coldly and turn a deaf ear;
The ghost race seeks to break through the barrier and invade, washing the world in blood, yet righteous cultivators only calculate how many spirit stones they can squeeze from the chaos and how much their cultivation can advance.
Order has collapsed, good and evil have blurred, and hell is everywhere in the mortal world.
If no one will uphold justice, then I will wield the sword of slaughter.
I will not play the saint, show mercy, or harbor feelings. I will cultivate only the path of slaughter.
Blood debts must be repaid in blood. If you refuse to submit, I will fight until you die.
All who owe me, wrong me, or bring calamity upon the living shall be slain! No mercy!
