The more Luke approached the old library, the more he found goblins and had to take them down. It seemed that they didn't know that survivors were there, but they were searching in the right area… to the point where Luke began to wonder if it was a good idea to lead footsteps toward that place. However, when he shared his concerns with Shalia and Rina, Shalia used her magic to manipulate the snow and erase those. That consumed a constant amount of mana, so Luke had to fight the goblins without relying on magic… even more so when she had to bury the corpses deep in the snow.
When the sun was starting to set, Luke found the library. He had to look for quite a while since the building wasn't that tall and was mostly buried by the ice and snow. After walking around the building, Luke found an open window. It was big enough for an armored adult to use, and all the others had been frozen. It was clear that such a thing had been made by human hands.
