"There's no need to clean up, right? You guys didn't produce any non-recyclable trash. These things might even become an archaeological site in the future~"
"Right~ speaking of archaeology~"
Seeing Feng Yuan pull out a high school Chinese textbook with a mischievous smile, Agunas's spectral form silently flicked its tail and said,
"Even if you leave that here, they won't be fooled. After all, Lorraine Tower hasn't exactly been careful not to drop things while time-traveling."
Feng Yuan handed the textbook to Carnas and said,
"Petrify it for me~"
"Aren't you planning to attend class? If I remember correctly, that's your textbook, right?"
Glancing at Agunas's spectral form, Feng Yuan said proudly,
"This is a copy. I can't wait to see what they'll think when they dig it up during an archaeological excavation~"
"They're probably going to curse Lorraine Tower privately."
