My Magic Teacher Doesn't Know Magic

In the infinite stream, Ed, who focuses on technology enhancement, found that he was trapped in a nesting doll. After GAME OVER, he traveled back to a self-made game. It was very happy not to die, but what made him immortal was that he actually became a magic teacher. System: "Please teach students how to use fireball as soon as possible." Ed: "I am enhanced by technology! Do you understand Gundam? Do you understand laser guns?" System: "After the mission is successful, you will be rewarded with a mecha design drawing." Ed: "You're so cruel!" After the task is completed. Ed: "System, what the hell is the mecha powered by magic? Where's my magic!" System: "The host is enhanced by technology... Not a magician..." Ed: "Me!!!" Ed discovered that after time traveling, he had changed, and so had the system.
