The Second World of Another World

By an accident, he came to another world, a strange world, where there is not only magical magic, but also superb technology. However, they are separated by a big river. They are two opposing forces. War is always their theme. Magic cannot defeat technology, and technology cannot defeat magic! His arrival broke the balance between the two places! He wandered between the two forces, constantly benefiting from them, learning magic and technology, and eventually became the first all-rounder from another world... Thanks to "Harry" for the cover~~
