The boundless huge Black Dragon seemed to be reflected outside the void, as if about to swallow the entire Guanjiangkou in one bite.
The grey color engulfed the whole world at that moment.
Only when Su Tu withdrew his stance did the grey gradually recede.
Meanwhile, the Heaven-Howling Dog watching all this had long been dumbfounded, staring at Su Tu with incredulous eyes.
"What is this spear called?"
Su Tu turned to the Heaven-Howling Dog and asked, his voice carrying a hint of hidden joy.
This was his first time using a spear, and yet it felt incredibly smooth. This exhilarating feeling was something he quite liked, and there seemed to be some terrifying presence residing in this spear.
The 'grey' was just a corner of that existing power overflowing, and even that corner already possessed such terrifying might.
With this spear, Su Tu, originally already astonishing in combat, felt even more divinely aided.
"Black Dragon Celestial Extremes..."
