The first stage was to rely on Chinese herbal fumigation, assisted by acupuncture treatment.
The second stage would eliminate fumigation and focus only on acupuncture treatment on the back.
By the third stage, things would be much more convenient, with no need for acupuncture, just requiring Fang Qinglan to take the herbal medicine daily, at which point her condition would be thoroughly stabilized.
However, the three treatment stages were intermittent, with a break needed after the first stage before the next stage of treatment could begin.
After treating Fang Qinglan last time, Chen Erniu had taken her pulse and felt that it was very steady, suggesting there shouldn't be a need for further fumigation and acupuncture treatment.
Little did he expect that Fang Qinglan would suddenly say she was feeling some discomfort, which puzzled Chen Erniu greatly.
