Listening Song to become OP

!!!Attention!!! English is not the main language, please understand if there is wrong grammar or inaccurate word choices, my initial goal in writing this fanfic is to be better at English. I can read and speak English but I have a hard time writing it and I hope you guys enjoy this fanfic. This fanfic is more of a wish-fulfillment story so if you don't like stories like that don't waste your time on this garbage. ============= let's get this straight, the old mc world was purely my imagination, because I wanted something unique and rarely used, although there are some characters that use references from the original world , but that's just for the plot(manga = money) power houses in the old world can destroy the universe easily, and that's why they fight in another dimension . The power house has the title Star Seed, a human from the ninth dimension who incarnated into a human in the first dimension. humans can only breakthrough up to the ninth dimension, only the chosen ones can penetrate the tenth and eleventh dimensions where the angels are, and the twelfth dimension is the throne of the gods. ============ disclaimer: don't think this fictional work is real
