"The secret manual is real, but the most important portion had been destroyed by someone else, leaving behind an incomplete version. That is the reason why you are in such a state!" After which, Zhang Xuan did not continue to linger on the topic: "Alright, I will be performing acupuncture on you to resolve the hidden problems in your body!"
"Yes!" Du Miaoxuan took a step forward hurriedly.
With a turn of Zhang Xuan's wrist, a silver needle appeared. Then, with a flick of his finger, the needle flew straight at Du Miaoxuan.
The Library of Heaven's Path only revealed basic information and the person’s flaws; the way to solve their problems are not written in it. However, Du Miaoxuan's problem is similar that of Ling Tianyu's wife, and he had blockages in his meridians. This caused the blood of the Snow Wolf to fail in achieving its original purpose.
Zhang Xuan just had to clear the blockages to settle his problem.
