Qin Feng went all out without any hesitation and gathered dark runes onto his dagger, as if it was shrouded by a black layer of light.
It was rare for dark abilities to showcase their presence, hence, some might not even be able to detect it.
After a few rounds of battles, Qin Feng had managed to grab hold of an opening and pierced through the arm of the elder.
Within a short period of time, the arm of the elder turned pitch-black and deteriorated continuously.
Any ordinary person would last for a short while but due to old age, it was obvious that the elder had a problem coping with the dark abilities that were devouring his life energy and striking a deadly attack onto his weak point.
"You, how dare you use poison!"
The elder roared in anger, as if Qin Feng had committed some unforgivable sin.
"Regardless of black or white cats, only its ability to take down its prey defines its capability, it is my own decision to use poison!"
