Travel Through Time to Be a Brave Man, God Gave Me the Talent to Transform into a Dragon

[Western Fantasy + Time Travel + Brave + System + 1v1 without harem] What should I do if I am summoned to a different world to be a brave man, but get the identity of a dragon first? As soon as Lin Xiao was summoned to a different world to be a brave man, he discovered that he had acquired the talent of "transforming into a dragon", and even his race seemed a little wrong. Others are not all brave dragon slayers who eventually become evil dragons. How come I seem to be an evil dragon at the beginning? When the other brave men go to fight the evil dragon, I can't be the spy who tells the truth. Do I have to fight myself? Question: If I do some evil first, prove my identity as an evil dragon, and then surrender to myself, will the system reward me? Okay, just kidding, actually my wish is... World peace—— [When seeing Lin Xiao's performance, Great Magician Edgar: 6, how did you learn Dragon Word Magic without any teacher... Evil Dragon: 6, the new clansman appeared out of nowhere...
