Become a Devil from a Magician

Good news: I have traveled through time, am a magician, and have a lovely sister. Bad news: I'm disabled, my parents are dead, and it was probably my sister. As a time traveler, Luo Zhen felt that he should fight with his golden fingers. From then on, there was an indifferent demon king in every world. Loki: "What? That kid went to the dungeon to challenge the floor master again? Didn't you let him rest?" Freya: "As for the title, I think Freya's Puppet Master is pretty good." Finn: "This guy always does things that make people both love and hate him. For example, the appearance of the floor master from the Apollo Familia is definitely related to him." Riveria: "I am a troublesome but extremely talented child. Also, don't ask me my age, I am 18 years old." Grace: "If this guy wasn't so slippery, I'd really like to train him." Lefiya: "Senior Luo Zhen is the best puppet master in Orario." Aisi: "Luo Zhen is very strong." This novel and its characters are purely fictitious.
