After flipping open the notebook and seeing its contents, Rocky realized that it was actually a journal!
Era 1018, May 12th.
"The demons have been in the city for a month now, Kasin City is done for, only we are still alive..."
Upon reading the first two sentences of the journal, Rocky's brow furrowed tightly, it was clear that the journal was written after the demons entered the city, to be precise, a month after the city had been occupied, and what exactly had happened in Kasin City during this time was exactly what Rocky wanted to find out, so he hurriedly continued reading the notebook.
"I always thought I was lucky, being inside this research institute when the demons invaded the city, and that's why I managed to escape disaster, but now I find that things are not as simple as I thought because I've seen almost all the researchers here, and the defensive power of this place is so strong it's obvious that it was set up in advance, which is simply unbelievable."
