I was a small fish when I reincarnated, but I heard I can become a dragon, so I'll do my best

After being reborn in a strange new world, I found myself as a tiny fish swimming in a vast river. My memories of my previous life were hazy, almost nonexistent. But then, a mysterious presence—calling itself the Voice of Heaven—whispered in my mind, revealing an incredible destiny. If I worked hard and grew stronger, I could evolve into a mighty dragon. The idea ignited a fire within me. Eager to rise from the weakest creature to the most powerful, I threw myself into the hunt, chasing experience points and leveling up. Magic, skills, and hidden abilities I never imagined possible existed in this world. My journey had begun, starting from the humblest of forms—a mere fish—but my ambitions soared as high as the heavens themselves. The path to greatness wouldn’t be easy, but I was determined to reach the top.
