Fang Rui's Boundless Sea simply idled his time away at the spawn point, a bend in the canyon. He was showing that he intended on standing around and waiting there.
Zhou Zekai's Cloud Piercer quickly made his way past the midpoint and then began paying attention to his surroundings. Although Fang Rui's Boundless Sea couldn't climb like a Ninja could, there were quite a few footholds on the walls. Reaching the top of the canyon wasn't a feat that only a Ninja could accomplish. It was just much easier for them.
The canyon walls continued to blur past him. Even though he had begun checking his surroundings, Cloud Piercer hadn't slowed down. He was already carrying his two guns in his hands. Boundless Sea hadn't appeared yet, but his guns were still pointed straight ahead, filled with killing intent.
The viewers watching knew that all of Zhou Zekai's efforts right now were futile because Fang Rui refused to move. There was no need for him to be so vigilant.
