Capítulo 407: Investigation (Part 2)

'A physical lock? how strange'

That made no sense, after all, why would a lock be physical in melki's academy of magic, the normal one would obviously be a magic chest. 

[If you think about it, it makes sense Luke. After all, within the academy there are several skilled mages... So a physical lock avoids that problem]

Luke then tried to open the safe, using a piece of metal that was inside his inventory. The young man tried to make lock pick on the safe, but realized that this task was a bit more complex than it should normally be.

'That lock is different, I have never seen something like this'

[So... It must be some extremely important document]

'It probably is'
