Grey stood in the same position, holding his sword casually. The attack he used against the two young ladies was very simple, explosive speed.
'My physical strength should be around the Fifth or Sixth stage now.' He thought to himself while looking at the dumbfounded group of three.
The group looked at him with dread, with a hint of fear appearing in their eyes. Grey's capabilities scared them. Having such speed meant that it was almost impossible for their attacks to hit him since he could easily dodge it.
"Wait, he's also a Lightning Elementalist!" The second young man in the group exclaimed.
When Grey used inscriptions the first time, he attacked with the fire element, but his blade was coated with the lightning element. This explained his explosive speed, but to a certain extent. After all, he wasn't the only Lightning Elementalist in the world, but the group hadn't seen anyone that's as fast as him.
