At this moment, inside the patient's room.
Ren Feifan was being serious, with a slight twitch of his finger, a silver needle appeared between his two fingers.
Next, with a shake of Ren Feifan's arm, the silver needle was headed straight for the Guan Yuan acupoint of Man Zi's mother.
Throughout the process, Ren Feifan made a great effort to control this silver needle.
Controlling the silver needle depleted Ren Feifan's energy severely.
Luckily, Ren Feifan's cultivation had reached the Earth-level Realm, so this kind of exhaustion didn't put too much strain on him at present.
The silver needle landed on the Guan Yuan acupoint of Man Zi's mother, it shivered slightly with no intention to stop, and Ren Feifan could also clearly feel a faint Qi emanating from the needle.
