Immortal in the Heavenly Prison: I Turned the Demon Emperor into a Pet

A jailer in the imperial prison from the start: while the world outside is locked in bloody conflict, I'm invincible at max level behind bars! #InvincibleLead #Immortality #Lighthearted #PlayThePigToEatTheTiger [Immortality + Imperial Prison Sign-In + Mastermind Behind the Scenes + Farming and Raising] This world is too dangerous. Dynasties rise and fall, demons run rampant, and geniuses spring up everywhere. Su Mo decides: “I'd rather die than leave the imperial prison!” As long as you can keep your head down, even immortals will turn to dust! Here, he saw off the all-conquering leader of the Demon Cult and obtained The Heavenly Demon Strategy; he outlasted the martial arts legend who had once dominated the age and inherited the Asura Blade; he even outlasted the Demon Emperor, hailed as the greatest of all time, until the beast lost its temper and became a docile fox that warmed his feet. Then one day, the Great Zhou Dynasty collapsed, and countless demons stormed the capital, intent on razing the imperial prison. Su Mo, who had quietly been sweeping the floor all along, sighed and set down his lunch bucket. “I'm just a jailer who delivers meals. Why are you making me step in?” That night, not a single demon remained in the capital, and the imperial prison was declared off-limits.
