The Silver Needle, carrying with it Northern Spiritual Energy, slowly penetrated into Xiao Kunkun's Dantian. Ling Zhenfei held his breath and focused, not daring to be careless for even a moment. The doctors and nurses observing the procedure, all professionals in traditional Chinese medicine, also understood the crucial importance of this stage and held their breaths in silence, afraid that even the slightest noise might disturb Ling Zhenfei's treatment.
Snap!
Suddenly, a faint noise was heard as Ling Zhenfei's Silver Needle seemed to strike against something hard. Then, to his surprise, it began to shake violently. Shocked and having never encountered such a situation before, he struggled to suppress the trembling of the Silver Needle, endeavoring to keep it stable, but it began to shake even more violently, now visibly shaking to the naked eye.
