"Okay ..." Ling Qingxue nodded her head obediently and got into bed.
Xia ruofei climbed onto the bed and hugged Ling Qingxue's body from behind.
Very quickly, he heard Ling Qingxue's breathing slowly become even. She had clearly fallen asleep.
Xia ruofei's eyes were wide open, and he did not fall asleep for a long time.
Ling Qingxue's progress was much faster than he had expected. Once Ling Qingxue broke through to refined Qi Level 3, in addition to her spiritual power reaching the early stage of spiritual palpitations, she would be at the same level as Song Wei when he was cultivating with her spiritual body.
Furthermore, Xia ruofei's spiritual power cultivation had broken through to the spirit gathering realm. His control of his spiritual power was much better than when he was cultivating with Song Wei.
In other words, once Ling Qingxue broke through to refined Qi Level 3, she could basically start trying to practice spirit - body Fusion.
