Seeing that Patriarch Huyan was going all out caused killing intent to flicker within Meng Hao's eyes. Patriarch Huyan was in a state of mindless madness, but his battle prowess had leaped up, and was now completely beyond what it had been before!
Considering that Patriarch Huyan had entered such a state, Meng Hao had the option of simply dodging his attacks, then waiting for enough time to go by for this version of Patriarch Huyan to dissipate naturally. However, the desire for battle was thick in Meng Hao's eyes. This was a fight to prove the power of his Cultivation base and achieve mastery of his divine abilities and magical arts through actual use.
To Meng Hao, this battle was a way to gain understanding and control over himself, to grow more perfect. Now that he was facing Patriarch Huyan's most powerful divine ability, Meng Hao… had absolutely no desire whatsoever to flinch away. He would fight!
