Chapter 668: Ling Yun - Mu Shu*

Ling Xi sighed after she heard that. "Sometimes I can't read Ling Yun's mind, so I don't know yet how long we'll stay in Bai Zhongyi's realm, but it would be better if we go after he reaches the Emperor Realm."

"Huh?" The two spirit women were surprised, and Lei Lin asked her. "Isn't that too long, Big Sis? I know Ling Yun's cultivation is very fast, but I'm not sure if he can reach the Emperor Realm that fast, even if they are all helping him by dual cultivating with him."

Ling Xi shook her head. "There are no humans in Bai Zhongyi's realms, so the Qi there is much stronger and denser. Ling Yun doesn't need to restrain himself like when he was on earth, and he can absorb the Qi there at full speed without worrying about people's fate."

"That's true." Lei Lin nodded in agreement with that. "However, even if he managed to do so, it would only mess up his foundation. So... Ouch... why did you smack my head, Big Sis?"
