The Long Journey After Becoming an Ancient Dragon

"I am just an ordinary man, living in an ordinary city. After my death, I was reincarnated into a magical world and ended up as an ancient dragon. This world is still in its early stages, with languages, civilizations, and knowledge gradually developing. In order to pass the time, I observe the rise and fall of civilizations, witnessing the birth of different languages, sciences, and arts. As a dragon, I watch over and accompany humanity's growth and progress through the ages, exploring the mysteries of the world and learning the meaning of eternity in my eternal existence."
