Mountains and Sea in the City

What kind of world is this, full of magic, illusions, and supernatural powers. The "Department of Magic" rescued a young man with black hair today who was involved in a magical incident. The young man with black hair had no magic power in his body and was a real ordinary person, but the Forgetting Curse had lost its effect on him. My name is Xu Sheng. This world is strange and familiar, but full of all kinds of magical creatures. I was inexplicably involved in magical events. In order to survive, I joined the "Magic Department" and worked as a handyman. That day when the "Department of Magic" was exploring the ruins, they received a yellow parchment. No one could understand the complicated square symbols. The great magician said it was a formation, and some said it was a special symbol. Xu Sheng saw the yellow parchment scroll, which had "The Scroll of Immortality" written on it.
