Room 43

Alex wanted to test out a few things and then cultivate to get back the Qi he would have used up in the future. Considering all that, he decided that 6 hours was necessary for him at the very least.

For 6 hours, it cost him exactly 480 Immortal Spirit stones.

The woman at the counter wasn't as bothered as she would have been, had she been able to properly sense what cultivation base he was in. She could tell that he was on the weaker side, but not exactly how weak.

The Immortal Concealment technique came in handy during such cases. He couldn't hide that well from people who were way stronger than him, but from someone who was just a little stronger than him, it worked amazing.

The woman handed over a small metal piece in the shape of a stamp with intricate details on it. That was the key to the room on the 12th floor. The number of the room, 43 was written on the back of the handle.
