I Ask You to Save the World, and You Go on Stage to Sing and Drive the Gods and Demons Crazy

Gods and demons are coming, doomsday catastrophe, I have bound the [playing system]! Others fight bloody battles, but I can level up just by singing on stage! A song "Dingjun Mountain", the sword comes! Cut off the head of the evil god! As soon as "Havoc in Heaven" comes out, sticks start! Overthrow the Demon Temple! The whole world thought I was a lunatic hiding behind the scenes, but little did they know that the gods and demons regarded me as taboo! The aloof God King knelt down and wailed: "Please stop singing! I will kowtow to you!" I put on facial makeup and a big cloak, looked at the shivering gods and demons in the audience, and smiled slightly. "Don't worry, tonight's finale is "Gods and Demons"!"
