The Person Who Sends the Dragon Home from the Dragon Clan

He slew the dragon of one hundred and twenty years. Nineteen dragon bone swords were inserted into his waist, and a broken harmonica was carried in his arms. Loose cultivator Tianyuan, a living legend, a person who does not exist on the roster. A letter from an old acquaintance lured him into the academy: "I discovered a special bloodline. S-level, but more complicated than S-level." The owner of that bloodline was currently worried about failing exams and having a secret love. The old man didn't know that what he was going to send home this time might be a dragon, or it might be the whole world.
