Jiyuan, the Demon Venerable and greatest fiend of the Three Realms, fought his way through the Immortal Realm over a thousand years of bloodshed and drove back the Heavenly Emperor. At last, the day of his ascension arrived. All the demons wept as they saw him off, but during his tribulation, the Heavenly Dao punished him, casting him into a youth-restoring tribulation and turning the peerless Demon Venerable into an adorable three-and-a-half-year-old toddler.
His former majesty was gone, replaced by a baby voice and tiny hands. He still had his magic, but his body was so fragile that the slightest exertion would cause a backlash and leave him gravely wounded. The demons were beside themselves, yet didn’t dare laugh out loud. His enemies, long lying in wait, seized the chance to stir up trouble. The Northern Border Demon Lord marched an army to force his way into the palace, only to be scared off by a single finger from the Demon Venerable.
With nowhere else to turn, the little Demon Venerable revealed a shocking secret: he was the Heavenly Emperor’s own grandson. He sent a crookedly written plea for help straight to Lingxiao Hall, asking for protection and something tasty to eat.
The Heavenly Emperor had been eager to eliminate him, but in the end, blood ties won out, and he personally led the heavenly soldiers down to the mortal realm. When the fiercest demon in the Three Realms becomes the three-year-old grandson the Heavenly Emperor must protect, the Demon Realm falls into turmoil and the Immortal Realm is shaken. Thus begins a hilarious yet intrigue-filled tale spanning the Three Realms.
