As Zhang Xiuer closed the door, Zhao Yang instructed Xu Xin to swallow one of the pills that had been prepared in advance. After a while, changes began to manifest in Xu Xin's body. His face turned as red as a glowing-hot branding iron, and a frightening redness spread over his entire body.
Zhao Yang knew that the medicine was taking effect, and that it was the best time to guide the flow of Qi. So, like before, he inserted eight needles into Xu Xin's head.
The Nine Reversal Needles were divided into five levels: five, six, seven, eight, and nine, categorized according to the difficulty in treating the illness.
Last time, Zhao Yang had only needed seven needles to bring Director Song back from the brink of death. Though the condition had seemed critical at the time, under the miraculous effects of the Nine Reversal Needles, only seven were required to do the job.
