Having mastered the Daoist arts, you're telling me you're in a world of demons and monster

On the verdant mountain, Jiang Xuanjing diligently cultivated the Heavenly Book's Daoist arts for years, finally achieving mastery. One day, he descended the mountain, sword in hand, only to find that across this vast land—in the imperial court, the emperor was incompetent, and the officials wicked; in the martial world, demons roamed freely, and evil spirits plagued the world. Humans ate humans, and demons ate humans too. The common people were drowning in misery, with no way to seek salvation. In such a wicked world, Jiang Xuanjing gazed at the supreme Daoist arts within the Heavenly Book and knew that by slaying demons and eliminating evil, he could obtain the Heavenly Book's Daoist arts. For sixty years, a Daoist, sword in hand, swept away all the demons and monsters of the world! Looking back, he saw only great joy on earth, while in the heavens above, countless immortals coldly surveyed the land. "I have come to the heavens only to demand that you 'demons' die! To prove the Great Dao of our generation!"
