After I Abducted the Demon Lord's Son, the Entire Immortal Realm Panicked

I thought I had done something incredibly important. I had secretly brought the Demon Lord's most beloved youngest son from the Demon Realm and personally delivered him to the Immortal Lord, bowing deeply and saying, "Your Excellency, the Demon Realm's hostage has been delivered." The Immortal Lord looked at me, his face gradually turning pale, as white as paper. Before I could react, my senior brother had already rushed in from outside the mountain gate, panting heavily as he tackled me, his voice trembling: "It's terrible! The Demon Lord has gone mad! He's grabbing the Grand Elder's beard, rolling on the ground demanding his son, saying he'll slaughter anyone who steals his child! Who did it? Who did it? Speak up!"
