"To think that once upon a time, I slaughtered immortals, punished demons, and took over the underworld...!"

Gu TianLang was once the infamous emperor of the underworld where he ruled over immortals and demons alike with an iron fist. Keyword here, “was.” When he incurs the wrath of the Heavenly Dao—an ancient ruler who has attained immortality and a demonic higher power—his people turn on him and lay siege to his castle. Surrounded and outnumbered, Gu TianLang gets ruthlessly and publicly stripped of his powers, smote, and dies.

Only, thanks to a mysterious jade, he wakes up 500 years later! Will he be able to exact his revenge on the Heavenly Dao and get his kingdom back?!
