I Have Become an Agent of The Universe!

Li Ao had always been the most infamous troublemaker of the Holy Capital. Though he was talented, he spent most of his time reading rubbish novels by mortal writers, wreaking havoc in the family estate, and angering his grandfather to death. After creating a huge blunder in the Royal Palace, his grandfather locked him into the family dungeons as a punishment. But right after being locked in the dungeons, a mysterious voice called out to him, assigning him to the position of an Agent of The Universe! What is this weird system, why does it shit-talk him, and what does it mean to be an agent of the Universe? [Also on Royalroad!]
