"What major leak? That book?"
"Yes. It's the Angel Clan's forbidden spell—the Un-series Apocalypse!"
"Un-series Apocalypse? What is that?"
"All the schools of magic known to the host, be it light, darkness, life, or the elements of wind, fire, water, earth, and wood, are considered elemental. And opposed to elemental is the un-elemental."
"Un-elemental?"
"It's just that this forbidden spell is incomplete, unfinished. According to Xiaomei's speculation, a complete Un-series Apocalypse could turn a painting into blank, empty paper as if it had never existed, and even the person who painted it could be erased."
"What if it's used on a person? Wouldn't the whole person disappear?"
"Indeed, that's the forbidden spell! Xiaomei can deduce it, but it will take a very, very long time."
"Who created this Un-series Apocalypse?"
"The Fallen Angel."
