Magic from Another World

A strange thunderstorm came, and more than 40 people in the class were collectively reincarnated into different timelines in a different world. Some people ascend to the throne and their names will remain in history; some people fall into darkness and will be infamous for thousands of years. And I, starting from scratch, personally developed my own magic system, vowing to show the whole world how cool magic should be! Former classmates meet again. Are they close friends or mortal enemies? What kind of shocking secret is hidden behind this bizarre thunderstorm in which everyone is reincarnated? All the truths and legends will be unearthed by me, starting from scratch! (There is no Holy Mother, no wisdom, and there will be no thunderstorm elements, so please rest assured)
