Lv Kai hastily stripped off his clothes.
Zhou Yu took out a pack of silver needles, walked behind him.
Then, with swift movements, he took out seven silver needles and swiftly pierced them into the seven major acupoints on Lv Kai's back.
Following that, Zhou Yu struck Lv Kai's back with a palm.
In an instant, a surge of black Qi emerged from Lv Kai's body, accompanied by a faint and eerie sound.
The entire room instantly became grim and foreboding.
When the black Qi had gathered to a certain extent, it suddenly condensed into a mass and charged toward Zhou Yu as if intending to swallow him whole.
Zhou Yu snorted coldly.
"Overestimating yourself."
He waved a palm through the air, and a current of energy surged out.
The black Qi was promptly shattered.
The defeated black Qi split into several strands, trying to hide back into Lv Kai's body.
But at that moment, the seven silver needles on Lv Kai's back burst forth with a faint silver glow, trapping all the black Qi within.
