A Full-Time Mage, the System Called Me to Debut

Also known as "The Versatile Mage: The Everlasting Fire" [The heroine of the dragon world view + Schrödinger's harem + the death of the music system + the strange natural dual system] Muchenyu traveled through the world of full-time mage, searched all over his body, and finally found his golden finger. I originally thought about using this to reach the top, but when I took a closer look, I saw that the other party was actually a star development system? No, in a magical world where demons are rampant and humans are in decline, who is a good person developing the entertainment industry? ! The system remained silent and silently released the debut mission. Muchen Yu refuses to obey, there are policies from above and countermeasures from below! Debut? X Become stronger? √ I originally thought that the days would pass smoothly with him escaping and the system chasing him back and forth. Unexpectedly, one day, the accompanying black bird hairpin opened the door to a new world for him. Even the celebrity development system that fell in love with and killed him was just a facade... (To make up for some minor regrets, there is a world line correction mechanism for major events; focus on full-time mages, consider interspersing a few other elements)
