Zhang Ruochen was in a good mood, because he had reached the Black Realm's Advanced Stage and improved his cultivation greatly.
As soon as the day was breaking, he visited Black No.1 and asked Duanmu Xingling to fight against him as a way to improve his palm technique.
As his palm technique improved, Zhang Ruochen felt he was not far away from the success of "Dragon Shape and Elephant Shadow". He just needed an opportunity to break through it. This feeling was wonderful.
Zhang Ruochen didn't rashly break into Black No.1. He stood outside and channeled Genuine Qi into his voice. "Senior sister, I want to practice palm technique with you again. Are you in there?"
A moment later, Duanmu Xingling opened up the door and stared at Zhang Ruochen with a drowsy look. "Don't you sleep?"
Of course, warriors were also normal people who needed to rest but they just needed less. A Black Realm Warrior only needed two hours of sleep to recover energy.
