The Owl Array Master

Seeing Blackie cursing at him with such vigor, Zuo Li's expression kept on changed as he too wanted to curse back at the former. 

For it to be unharmed after sustaining two consecutive blows from him, with the second one launched with the Demonstone Engraving, Zuo Li could not imagine what manner of monster Blackie was. 

Zuo Li was no weakling, although his strength had not reached the third level beneath a Supreme Saint, he was not far off, and was definitely no weaker than Cang Long or Yan Ba and the likes. 

Although he did not cultivate the Demonic Tiger Roar Portrait, it was still the same demonic exercise contained in the Demonstone Engraving, and was essentially the same. Thus, he was able to unleash the Demonstone Engraving's devastating power. 

Based on Zuo Li's estimation, that blow earlier was something even a top-level sacred artifact would not be able to withstand, and inevitably suffer damage.
