One Sword to Subdue the Nine Heavens

There are immortals, demons, monsters, swords, and stories. The Peerless Prodigy, Marshal of the Heavenless Demons. A traveler from another world, a nobody. Two youths born of destiny set the world ablaze with war, and will bring an end to thousands of years of conflict. No one cares what nobodies think. No one cares whether they live or die. Who knows that nobodies have blood and flesh, and anger too? Abandoning the immortal path to cultivate the sword, bearing the burden of countless killings, fighting a hundred battles without retreat, choosing death over surrender, all for peace throughout the land. A chaotic age like a poem, filled with heroes who rise in a blaze of glory.
