Demons run rampant, and strange horrors multiply.
The living fear demons, and the dead aren't necessarily any more peaceful.
Xu Li is just a night-shift laborer at Beichang, hauling demon corpses and spending every day among rotting flesh and bloodied bones for wages that could cost him his life at any moment.
Until one day, he gains a special power from a demon's bones, and a book titled Martial Arts Record appears before his eyes.
**Consume demon marrow to deduce martial arts and break through limits.**
Everyone knows that the Bone-Pressing Stance has only four levels.
But Xu Li trains to the fifth, the sixth...
The limits of the human body, which ordinary martial artists struggle for decades to surpass, are repeatedly shattered before his eyes.
His bones grow harder and harder, his blood and energy grow ever more vigorous, and ordinary body-tempering martial arts gradually evolve into a terrifying power beyond even the imagination of their creator.
At first, Xu Li only wants to earn more silver so his older sister can live a better life.
Later, he discovers that he has embarked on a path no one has ever walked before.
When the demons that countless martial artists dread appear before the world once more,
they finally discover that something in this world is even more terrifying than demons.
**That is Xu Li, who has tempered his body to its utmost limit.**
