The Boy Who Slays the Dragon Will Eventually Become a Dragon

After reading the book, I discovered that I was actually the tragic loser male protagonist who was destined to die in the novel. It's a pity that I didn't read it a few more times to deepen my memory of the plot before traveling through time. What's more, it's a pity that the author of the original world is no longer around and couldn't write a complete ending. In order to avoid the outcome of being manipulated by others, I chose to deliberately hide my talent. Until the twin thrones in the world are revived one after another, only I can save the world! Many years later, I realized that fate cannot be changed - "The boy who slays dragons will eventually become a dragon!"
