Nie Rong and Nie Yuan flew in the sky outside the Imperial City. At the beginning, they’d intentionally slowed down for the sake of taking care of Duan Ling Tian, but along with them slowly increasing their speed, when they noticed that Duan Ling Tian followed unhurriedly by their sides from the beginning until the end, they couldn’t help but be stunned.
"Father’s cultivation is at the fourth level of the Void Prying Stage, whereas, my cultivation is at the third level of the Void Prying Stage… Little Tian is actually capable of following unhurriedly behind me while I’m flying at full speed now, and he seems to be at ease like Father." Nie Yuan couldn’t help but gasp. "Wouldn’t that mean that Little Tian’s current cultivation is already at the fourth level of the Void Prying Stage or above?"
Nie Yuan was shocked, and Nie Rong was equally shocked.
