Duan Ling Tian only knew his mysterious Eldest Senior Sister was Xu Lang's daughter. He had heard that she was even stronger than his Second Senior Brother, Lu Ji. However, he did not expect her to be capable of killing a titled Celestial Emperor. Since her cultivation base was weaker than that of a titled Celestial Emperor, this meant that she had other techniques up her sleeve to be able to kill a titled Celestial Emperor just like him.
"Little Junior Brother, you better not think you're the strongest among us just because you managed to kill Dugu Wen. Eldest Senior Sister didn't get a title from the Title Temple, but she had killed a titled Celestial Emperor in the past. In fact, her current strength is comparable to our teacher's strength," Hu Mei said teasingly. When she finished speaking, she glanced at Xu Lang.
