A Hundred Years Guarding the Prison

After transmigrating as a lowly jailer in the Great Zhou Dynasty's Demon Suppression Bureau, Su Ruhui discovers that this world is far too dangerous. Demons and monsters run rampant, imperial authority has fallen into the hands of others, and the martial world is rife with vendettas. Human life is worth less than grass.

Fortunately, he carries an **[Ancient Yellow Springs Codex]** with him. By suppressing and recording prisoners, or even just searching their corpses, he can extract their lifetime of cultivation, their techniques, and even their remaining lifespan.

Su Ruhui makes up his mind: He won't leave seclusion until he's invincible!

He hides in a dark, damp dungeon, seeing off one demonic fiend after another.

From the Blood-Transforming Saber Art to the Indestructible Diamond Body, from martial-world secrets to divine cultivation arts, he watches dynasties rise and fall from his prison cell, calmly observing the changing clouds.

Until a hundred years later.

That year, the demon emperor dropped his disguise and sought to offer the entire city as a blood sacrifice.

That year, immortal sects from across the sea descended on flying boats, treating mortals like ants.

That year, an ancient true demon deep beneath the earth awoke, and a demonic tide swallowed the mortal world.

The Great Zhou fell. The world descended into chaos. Everyone lost hope.

Then the old jailer who had swept the grounds at the Demon Suppression Bureau for a hundred years finally stretched and walked out the door.

"I just wanted to sweep in peace. Why do you all insist on pushing me?"

That night, sword energy swept across thirty thousand miles, and a single sword cast its icy light over nineteen provinces.

That night, he tore apart Nascent Soul cultivators with his bare hands, trampled demon gods underfoot, and mended the heavens with one hand!

Five hundred years later, in neon cities where technology and cultivation coexist, people still tell tales of the one who lives behind an ancient stone stele: the man who guarded the mortal world for five hundred years... the humble sweeper.
