Einster:
Proof must be shown to go upstairs quiuckly. The level of Dimensional Warp you completed determines which floor you can go to.
Many accidents have happened on floors 31 and higher. To protect researchers, we are investigation those floors. For now, I can send you up to the 26th floor.
Ah, you must determine how many Warp Crystals you will pay before asking me to send you upstairs. Which floor do you want to go?
