A hand suddenly gripped Fang Ling's nape forcefully, and with a surge of spiritual power and a slight shake, Fang Ling's spine emitted a series of crisp cracking sounds.
The body that Fang Ling had just tensed up in readiness to counterattack instantly turned limp like a noodle, and even the spiritual power that had just surfaced retreated back into his body due to Ye Zhen's shake.
"Ye... Zhen... what... what are you doing?"
This move of Ye Zhen terrified Fang Ling so much that his voice cracked as if he were about to cry. Ye Zhen's action had been too sudden, and the spot he had seized was the back of the neck. With a forceful shake, Fang Ling would be bedridden for the rest of his life.
The moment Ye Zhen expelled spiritual power from his hand, Fang Ling would meet his demise right there.
Such methods were only used seriously.
"Sister Caiyi, help me, Ye Zhen has gone mad, save me..." Tears streamed down Fang Ling's face, half from pain and half from fright.
