The Nine Netherworld Fighting Energy within Huang Xiaolong's body was like a runaway horse, running wild as a sign of a breakthrough.
Since starting his cultivation of Fighting Energy at the age of seven, Huang Xiaolong had made numerous breakthroughs and was naturally familiar with the signs of an impending one.
Huang Xiaolong quickly focused his mind and circulated the Asura Technique, forcibly suppressing the rampaging Nine Netherworld Fighting Energy.
Inside Huang Xiaolong's meridians and Qi Sea, the Nine Netherworld Fighting Energy circulated rapidly again and again.
At this moment, swirls of black mist began spiraling around Huang Xiaolong's body, the mist accumulating more and more until it completely enveloped him.
Huang Xiaolong's form was now faintly visible within the black mist.
