Eternal Lord

A man with supreme cultivation opened his eyes again and found that he had become a rebellious senior high school student who had just turned 18. He was surprised to find that his cultivation was still there, but was suppressed by the rules of this world and could not use it at all. In order to complete that mysterious task, he hid in the metropolis, and his layers of identity were slowly revealed. It's an imaginary world. If I don't write well, please give me some pointers. Thank you! !
