It took me nearly five and half hours to break the formation; I would have finished a little sooner if I am not busy with little something. Now that I am ready, it is time to opened the door.

Zip!

I did waste any time projected the formation on the door. "Hehe, Human, if you think you could open the door that I could not afte" It laughed and mocked me when suddenly it stopped when runes lighted up and the door opened, and I moved swiftly inside.

The Blood Rhinoman had remained stumped for a fraction of a second before it entered behind me.

Bang!

Not only that, but it had also attacked back the other Elite Grimm Monster who was trying to enter behind it. The other Grimm Monster cursed at it and tried to enter again, but by the time it could take a step inside, the door had already been closed.

I was a little stumped seeing something like it happened; it had been quite a while since I had seen the tribal rivalry among the Grimm Monsters.
