The Demon Refinement Technique is inherently an incomplete cultivation method. What Lin Fei is cultivating is the chapter on unblocking the meridians. However, Lin Fei has no idea what comes next. It seems like he might need something else, but this is what Lin Fei senses after cultivating.
It's like the feeling of sitting on an airplane, as if there's something down below, even if you can't see anything. That feeling of floating makes one feel uneasy. But for now, this is the only cultivation method Lin Fei has, and it works effectively for him, so he isn't planning to switch. He'll just continue cultivating slowly.
According to the Dou Sect master, the more abundant the Heaven and Earth Qi within, the stronger the power. Therefore, constant cultivation is very important for an Ancient Martial Artist.
