The Old Demon Lord and the New World

Thousands of years ago, he was Di Jing, the king of the demons, and the most powerful being in the Yuxu Realm. Perhaps due to the balance of heaven, the human race gave birth to Li Hongchen, who was extremely talented and unparalleled in ancient and modern times. After being defeated by Li Hongchen, his body was sealed in the ruins. He escaped from the ruins, his Dharma body was burned out, and he returned to his teenage appearance. Looking back on the past ten thousand years, the name that once made the entire Yuxu world tremble has become a legend. He didn't hate it. Li Hongchen made him feel the joy of fighting for the first time in his life, and the freedom from being bound by power and responsibility. He was confused as to why Li Hongchen gave him an eye, a double pupil, an opportunity to escape, and then disappeared. He changed his name to Lingjun and sat in the classroom of an ordinary higher cultivation middle school. This world is completely different from what he remembers. Humans and demons have classes in the same teaching building, spells are included in the college entrance examination syllabus, and mobile phones and flying swords are both in students' schoolbags. The battlefield that was once filled with blood is now a playground paved with plastic tracks. Wearing the unaccustomed Chinese tunic uniform, he listened to classes, did homework, and was dragged to the cafeteria by his deskmate to grab stir-fried pork. While he was silently adapting to this unfamiliar peaceful world, he was thinking about the answers to the questions Li Hongchen left for him. He discovered that there were still undercurrents of the new world surging under the peace, and even the faint pain of old scars. Does the new world still need a demon king?
