Time passed by as I continued to solve the formation; while I was doing that, the change had occurred around me.
As I had said, the Grimm Monsters have returned, and this time, they have brought the two leaders with them, but when they came, they found a surprise waiting for them too. We also have the leader of our own; she had appeared twenty minutes after the Grimm Monsters left and started to use one artifact after another to break the door.
Some of the artifacts had nearly broken the door before it had been reinforced; if that artifact of her had been a little bit stronger, she would have been able to break it.
More and more people came with passing time, while some left seeing every attempt of opening the door is getting failed. Not all of them left though, they know it is one of the best places in the Myles Campus with many good things inside, and if someone is able to open the door, they stand a chance to get those good things.
