"Z Shake" was just a quick direction-changing movement. Move left, move right, while continuously moving forward. The track looked like a "Z". But when this movement was made extremely quickly, the distance moved became extremely small. If the character completed this movement in the blink of an eye, then it looked as if he hadn't moved, only a shake.
If it was just to make the character "look as if he shook", then many players could do this. But for a player to use the "Z Shake" in an actual battle, then he definitely had to be a great expert. Just relying on this small movement to dodge the attacks, it showed just how precise this person's decision making and control was.
It wasn't only Blue River, but Thundering Light and the others all understood this. At this moment, while they were still shocked by this exquisite play, they saw Stolord rush up to two Goblins and hit them with his palm. A gust of wind blew out and the two Goblins flew out.
