Since returning from the He Family, Chu Keqing has shut herself in, except for the day she visited Chen Yan's house to deliver those medicinal herbs. Elder Zi has since not stepped out.
Over these days, she has been diligently studying the Cloud Sect Technique that Chen Yan corrected for her. After Chen Yan pointed out and amended those errors in the technique, Chu Keqing felt that many long-standing obstacles began to unwedge within just a few days of practice. The bottlenecks that were previously impossible to break through due to incorrect handling of Primordial Qi saw some loosening after a few days.
Even her cultivation and Tao Practice had slightly improved!
She was pleasantly surprised and gained even more reverence for Chen Yan — she had been cultivating for twenty years, and had reached a bottleneck for the past few years. Despite tirelessly practicing every day, her cultivation hadn't increased at all over the past two or three years.
