As Zhu Fei finished speaking, the silver needle "stuck" in the Murderer's chest suddenly trembled gently.
Instantly, the Murderer felt an itchy and numbing sensation originating from the meridian at his chest, rapidly spreading throughout his body.
Normally, the Murderer prided himself on his resilience, but, faced with this sudden itchiness and numbness, his willpower collapsed in the blink of an eye.
Moreover, he was currently immobilized by Zhu Fei's silver needle and couldn't move his limbs at all.
The itchiness was becoming increasingly clear and distinct in his perception.
Almost involuntarily, the Murderer immediately let out a piercing scream.
"Stop... stop it! Zhu Fei! Stop it now AAAH!"
Amidst his screams, veins on the Murderer's forehead protruded rapidly, and the muscles in his face twisted grotesquely together.
His eyes reddening, he stared fiercely at Zhu Fei and roared, "Kill me, just kill me now AHH!"
