What? You Want to Use My Music to Hatch Dragon Eggs?

This was an alternate dimension with a world of swords and magic, it was also a world dotted with giant dragons everywhere. Everyone would receive a dragon egg at a young age and would be tasked to practice musical pieces. These dragon eggs required their masters to hatch them with a musical piece. Just as all the youths were in the process of hatching their dragon eggs, Roke who was a genius musician transmigrated to this world. When he was still unfamiliar with the world, the instructor in charge of teaching them was already hurrying him to start performing. The befuddled Roke had no choice, so he just casually played the piece “Victory”. The next moment, a gigantic magic matrix appeared. His dragon egg started to crack and a strange baby dragon that even the instructor wasn’t able to identify appeared. The high priest known as the Prophet of the World gave his final prophecy before he died, “I saw the victory."
