The Extraordinary Academy was in H City, and now there's a theater in H City where they perform magic music.
Cai Zi woke up to this ability and was overjoyed.
If humans can use extraordinary powers, robots would feel it's unfair if they couldn't, especially since they now possess intelligence comparable to humans and understand almost all human emotions.
Fortunately, relevant research hadn't forgotten them and had invented corresponding solutions for them.
By attaching a synthetic component to their extraordinary battery circuit, they could construct the simplest of reactors and then, through energy training, strengthen and upgrade the reactor.
For robots to learn musical abilities was very simple; they just had to download a set of software and then upgrade their fingers or mouth.
However, making music have magic power was something difficult to achieve.
