(I apologize, in Chapter 578, Yu Qing should have told Sisi about the Wanderer, not Ning Cheng. In fact, Yu Qing doesn't know Ning Cheng is the Wanderer. The original text has been amended.)
...
Ning Cheng's Divine Sense swept out, and he discovered that indeed there was no eighty-first floor above, and after going up into the void, he didn't know where one might end up. Since Ning Cheng still wanted to enter Xian Yu Star, naturally he did not wish to venture into the void.
However, Ning Cheng quickly understood that he must go up. He had searched the eightieth floor for a whole day and found no other exits except the way up.
Not wanting to be teleported to the square above, Ning Cheng could only surge upwards in flight.
When Ning Cheng's feet touched solid ground again, the void he had previously sensed with his Divine Sense had disappeared. The entrance behind him was also gone, and he was still inside a floor of the tower.
