We ended up running all around the place after being chased by the protein madman. Despite how heavy he looks like, he was so agile and he can run like an athlete. I have to carry Anya to make sure we can get away from the monster.
The good thing so far is that no other monsters are trying to kill us when we run around the hallways. Except for this monster, not a single monster is currently blocking our way. It was quite troublesome for me to fight smaller monsters just to escape this abomination. Thankfully, I don't have to do that and just continue to outrun this monster.
And thanks to me running around from the protein madman, I managed to cover the whole area and map it to my Insight. Still, this madman is just fast enough to keep up with me. I can't believe that even with my full speed of running by enforcing mana to my legs is not enough to outrun this abomination.
