Immortal Jailer: Lurking in the Heavenly Prison from the Start to Become the Big Boss

[Slow-burn + Strong Opening + Immortality + Shadow Boss + Ruthless and Decisive] Traversing to a chaotic world of immortals and martial arts, Xu Qian becomes a lowly jailer in the Heavenly Prison of the Great Xuan Dynasty. Demons and monsters rampage, eerie horrors run amok, the imperial court teems with treacherous schemes, and immortal sects regard all beings as ants.

Fortunately, he activates the [Longevity Dao Fruit], with his cultivation automatically increasing each year. As long as he doesn't die, eternal life is guaranteed!

Thus, Xu Qian adopts an eight-character motto: Steady development, prepare endless contingencies.

He sweeps floors and delivers meals in the Heavenly Prison, appearing utterly harmless, but in secret, he farms skills from demon prisoners and uses karmic divine powers to stir up tempests.

Today he picks up a bit of the Hundred Ghosts Night Parade Diagram, tomorrow he secretly learns a move of the Heaven-Cleaving Sword-Drawing Technique.

Colleagues see him as a nice guy, superiors regard him as reliable and hardworking.

Yet behind the scenes, he silently becomes the black hand shaking the world.

Until one day, the supreme Demon King breaches the imperial capital, intent on razing the Heavenly Prison.

In everyone's moment of despair, this usually meek sweeping jailer slowly raises his head...

Many years later, Xu Qian grasps the wheel of reincarnation, founds the underworld "Longevity Heavenly Prison", establishes eighteen levels of hell, and reshapes the order of yin and yang.

Looking back on the past, he smiles faintly: "Initially, I really just wanted to survive by laying low."
