Transfer Student from Underworld

When I woke up, I suddenly found that there was an underworld in my body. There was a bookstore in front of the house, and there were eight repeaters in it. They were Her Royal Highness the Princess of the Demon Realm, Yue Shuangxing, the descendant of Guigu Valley, the second female devil of the Demon Realm, the goddess Qingxiang, the immortal Fuyao, and the emperor of the human race... And I was lucky enough to become the first transfer student in history as a mortal. In the dark, there seemed to be a voice calling. On this day, Qin Wen suddenly raised his head and vowed together: Deep in the Nine Netherworld, in the Hall of Yama, there are ghost fires, burning my remaining body. As soon as the oath came out, a vague fog emerged, and the vast underworld suddenly showed the tip of the iceberg: "Welcome to the 2003 Underworld Cultivation No. 1 Middle School."
