Three days

"Then that is our way in," I nearly jump up from the desk and head to the Headmistress' office right now, but Lei's uncertain expression stops me. 

"We know what she says, but we don't know the intent or the actions behind the spell to properly unlock it," he explains. 

Right, that's a good point. I was only able to record audio, not video since that would have been too obvious. "So we need video now?"

"It's likely the office of spelled against video recording, but we can give it a try." Lei answers with a sharp nod. 

"Which will give us another chance to study it in person...So, we need to break in again?" 

"We do," Lei says simply while Teo groans. 

"You can sit this one out Teo, you've already done more than enough to help," I voice while looking into her concerned eyes. But the look she is giving me is resolute as she narrows her eyes at me.
