Since Bai Xianer had already turned into a human, that meant she had passed the Heaven's Tribulation test. Her tribulation was a success.
Bai Xianer was the challenger of the tribulation. The only reason she dared to continue chatting with Ling Yun and put on her clothes was because she felt that the black tribulation clouds above her disappeared completely. She knew that her Heaven's Tribulation had passed.
Ling Yun's tribulation experiences were padded as well. He had even gone through the terrifying Heaven's Tribulation during his tribulation phase. Obviously, he knew that Bai Xianer had already passed her tribulation. Otherwise, there was no way he would have rushed over so nonchalantly.
As for the tribulation clouds above them, Ling Yun's full attention was on Xian Er. In that moment, he didn't think about it any further. He instinctively thought that the Heaven's Tribulation was different because he was in a different world.
