Fight to the Death Across the World

He was nothing more than an ordinary swordsman.

He was nothing more than a martial arts fanatic.

For the sake of a secret manual, he could slaughter an entire family.

To break through a bottleneck, he would challenge masters from every school, even if it meant risking his life.

He saw romantic entanglements as poison.

He treated gratitude, loyalty, and benevolence as a joke.

He was a man so obsessed with martial arts that his obsession drove him to madness.

A grandmaster, a great villain, a legendary authority of his age. He was Helian Ren.

P.S.

The protagonist is ruthless. Self-righteous readers, please give this one a wide berth.
