Since the Hell of Moulting was rejected by Ye Xiajie learning it would make his wife remove his skin all over and regenerate it from the start, they've skipped the said layer. They already have all the stamps printed and the stamp itself. They could leave this first phase any time they wanted and were only waiting for their teams and assembled together so they could enter the next phase.
DING!
It is the sound of an elevator opening door. It was the couple, Hei Anjing and Ye Xiajie together with their families, Zhi Yang and Zhi Yue.
Getting out of the elevator, they've finally reached the fifteenth layer. The Hell of Ripping tongues. The couple rearrange their clothes from the play they did inside the elevator. Obviously, though it wasn't as explicit as the final base, it was still wilder than what a normal couple does. The swollen lips of Hei Anjing say it all.
