"I'll lend you a blade to cut down every enemy you have. You have three years to repay me with ten treasures of equal value, or... I'll take back this blade and your life."
Chen Yan, the good-for-nothing third young master of the Tian Gong Chen Clan, a renowned weaponsmithing family in the Eastern Domain, is found to have an "Absolute Spirit Constitution," which makes cultivation impossible. While his family looks down on him, he unexpectedly awakens memories of a past life: he was the Godslayer Smith, who forged forbidden weapons for the War Against the Gods.
In this world, demonic beasts run rampant and evil spirits are everywhere, yet the art of forging weapons is crude and primitive. Chen Yan rises to prominence with his astonishing Spirit-Sealing Forge technique, sealing the souls of demonic beasts inside weapons to give them life and supernatural abilities. He forges blades of vengeance for the desperate and establishes three rules: he forges, gifts, and lends weapons. Those unable to pay can borrow a blade, but once the deadline passes, the Weapon Hall will collect its due.
From saving a one-armed hunter and a blind musician to giving hope to a sword cultivator whose sword bone was stolen and an alchemist whose innate flame was taken, he gathers ten borrowers and quietly establishes the Divine Weapons Hall. Its name resounds across the continent through countless tales of underdogs turning their lives around, drawing Chen Yan into conflicts with ancient weaponsmithing guilds, greedy sects, and even awakening gods.
However, Chen Yan gradually discovers that his awakened Myriad Weapons Divine Body and the ancient Path of Spirit Sealing conceal an ultimate secret: when the sealing art reaches its peak, it will no longer be limited to demonic beasts and spirits. It will be able to seal laws and refine the world itself. After ending the war between gods and demons that sweeps across the heavens, Chen Yan faces a devastated world and the restless spirits of the Weapon Hall, and makes a choice no one has ever made before.
