"Body reinforcing pills? Aren't you a bit too strong for them to have any use for you?"
After sealing off all the entrances to the library and going back to the surface through the tunnel connecting to Monica's mansion, I inadvertently stumbled on my former teacher.
To be frank, this was quite an excellent opportunity, as I didn't want to bother with a massive crowd of people stopping me from doing literally anything. Be it to express their gratitude, ask for information about what happened or even blame me for killing the people that they believed to protect them. Chancing upon Monica just like that, allowed me to save myself the trouble and obtain everything that I needed without going for an extra mile for hiding from everyone else with my illusions.
