Chapter 1241: Yan'er, You Must Remember

Rong Sheng spoke softly, "If you want to use the Soul-Consuming Needle, I can be your test subject, and I can also correct you."

In the field of medicine, she was willing to contribute herself without reservation.

Su Yingxue smiled with relief, feeling a significant weight lifted from her heart.

She tested the effectiveness of the Soul-Consuming Needle on Rong Sheng, who after experiencing it, despite the extreme pain, told Su Yingxue, "The essence of the Soul-Consuming Needle lies in the control of the magnetic field. If used properly, it can heal; used maliciously, it can reverse meridians—a technique for healing as well as for killing."

Su Yingxue looked at the set of silver needles in her hand, lost in thought.

Rong Sheng taught her about magnetic fields and continued researching with her. Although they did not complete the final needle technique, she taught Su Yingxue how to arrange the needles in an array.
