Yunling, a low-level medicine slave in Qingming Valley, seems to have little spiritual power, but in fact, in order to protect the secrets of the sect, she secretly practices the forbidden technique "Star-Guiding Needle". After the Blood Demon Palace raided the Qingming Valley, she used the "Green Sac Resuscitation" technique to treat the wounded during the day, and at night she transformed into a secret guard who used silver needles to break demons. One night while exploring the devil's cave, she unexpectedly discovered the flaws in Demon Lord Ye Jin's cultivation and his conspiracy to plunder his spiritual veins. During the many confrontations between the two, Yunling's true strength was gradually exposed, and Ye Jin became paranoid about this weak medical practitioner who could hurt him. When the Demon Palace activated the "Blood River Formation", Yunling was forced to fight head-on with the ultimate medical move.
