The Ancient Age Awakens? I Guard Humanity, Unbeatable Forever!

The seven hundred and seventy-eighth year of the Great Zhou Dynasty.

Lin Yuan transmigrates into the body of an inconspicuous executioner in the Great Zhou Demon-Suppressing Prison.

The world is in chaos. Demonic cultivators stir up rebellions, fiends slaughter entire cities to practice their arts, heretical cultivators kill to transform themselves into evil beings, monsters emerge and churn the rivers, ghosts wreak havoc in broad daylight, and evil Buddhas refine the people into fuel...

The realm is beset by turmoil, and order is on the verge of collapse.

In this perilous world, Lin Yuan stumbles upon The Book of Strange Tales. Every time he executes a criminal, he gains cultivation and rewards, and can also view a record of their crimes.

Execute the Flower-Picking Gentleman: receive the Face-Changing Disguise Technique and one hundred years of cultivation.

Execute a mighty figure from the Demon Sect: receive the Heavenly Demon Body-Severing Method and one thousand years of cultivation.

Execute the Wuwei Daoist of Taiyi: receive the Tao Te Ching, three thousand years of cultivation, and one ginseng fruit.

Execute the Bull Demon King of Ten Thousand Years: receive the Black Demon Mystic Bull Body-Tempering Scripture, five thousand years of cultivation, a mystic iron staff, and the ability to move mountains and overturn seas.

Execute the Senluo Ghost King: receive the Little Dream of a Thousand Autumns ability, eight thousand years of cultivation, and a fragment of the Netherworld Book.

Execute...

The Thirty-Six Heavenly and Seventy-Two Earthly Arts, divine abilities and cultivation methods, Daoist scrolls, the Heavenly Book and Earth Book, the Four Immortal-Slaying Swords, the Primordial One Qi, the Three Purities in One Qi, the Taiji Diagram, the Primordial Ren Water Peach Tree Root...

Years later, the Great Zhou collapses, and the world is transformed.

Nations wage war, demons and fiends run rampant, and ancient gods and demons emerge from the River of Reincarnation, looking down on the mortal world with indifference.

Yet without even realizing it, Lin Yuan discovers that he has become invincible!!
