"How do you close it? I didn't even see a door at the stairway." Sang Ning was once again surprised and asked Louis to demonstrate.
Louis led the guests into a small cabin.
Sang Ning looked down and discovered the wonderful secret of the hotel's design. The cabins on the sea level were ordinary wooden structures both inside and out, even the floor was wooden.
However, looking up from the suite below the sea, there was a fully transparent glass dome dividing the sea, with a spiral staircase connecting the suite and the cabin, which was incredibly ingenious.
Louis demonstrated, holding a metal ring the size of a keychain near the stairway entrance, and a circular wooden door slowly appeared and closed.
Louis handed out the metal rings to the guests one by one: "This little thing is the key to each of your suites. Whether you want to open the door or close the stairway entrance, this thing can automatically sense it."
