God-Killing Dragon Emperor

When he was a waste, he was often bullied and lost his dignity. After gaining strength, he regained his dignity, but he also realized that the world was inherently unfair. In order to obtain his own skills, others ruined his family and had to flee. When he gained great strength, he learned that his enemy was so powerful. However, he did not become timid because of the strength of others. He grew stronger step by step, trampling powerful enemies under his feet, and completely obliterating his own enemies. Gods come to kill gods, dragons come to slay dragons.
